Saya mencoba mengunggah file menggunakan Alamofire. Unggahan berfungsi dengan baik saat menggunakan File (NSUrl ), namun, sepertinya saya tidak tahu cara menggunakan NSDataopsi ini?

Inilah yang saya miliki sebagai ujian:

 var url:NSURL = NSURL.URLWithString("http://localhost:8080/bike.jpeg")

 var err: NSError?
 var imageData :NSData = NSData.dataWithContentsOfURL(url,options: NSDataReadingOptions.DataReadingMappedIfSafe, error: &err)

 Alamofire.upload(.POST, "http://localhost:8080/rest/service/upload/test.png", imageData)
        .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
            println(totalBytesWritten)
        }
        .responseJSON { (request, response, JSON, error) in
            println(request)
            println(response)
           println(JSON)
 }

Saya mendapatkan kode status 415?

Selain itu, bagaimana saya dapat mengirim parameter tambahan dalam unggahan?

Terima kasih

EDIT

Saya tidak menyetel Jenis Konten yang benar:

var manager = Manager.sharedInstance
manager.session.configuration.HTTPAdditionalHeaders = ["Content-Type": "application/octet-stream"]


let imageData: NSMutableData = NSMutableData.dataWithData(UIImageJPEGRepresentation(imageTest.image, 30));

Alamofire.upload(.POST, "http://localhost:8080/rest/service/upload?attachmentName=file.jpg",  imageData)
        .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
            println(totalBytesWritten)
        }
        .responseString { (request, response, JSON, error) in
            println(request)
            println(response)
            println(JSON)
}

Masih tidak tahu cara mengirim parameter tambahan bersama dengan unggahan.

Berikut adalah fungsi sederhana yang membutuhkan target upload url, parameter, dan imageData dan mengembalikan URLRequestConvertible dan NSData yang dibutuhkan Alamofire.upload untuk mengupload gambar dengan parameter.

// this function creates the required URLRequestConvertible and NSData we need to use Alamofire.upload
func urlRequestWithComponents(urlString:String, parameters:Dictionary<String, String>, imageData:NSData) -> (URLRequestConvertible, NSData) {

    // create url request to send
    var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
    mutableURLRequest.HTTPMethod = Alamofire.Method.POST.rawValue
    let boundaryConstant = "myRandomBoundary12345";
    let contentType = "multipart/form-data;boundary="+boundaryConstant
    mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")



    // create upload data to send
    let uploadData = NSMutableData()

    // add image
    uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"file.png\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
    uploadData.appendData(imageData)

    // add parameters
    for (key, value) in parameters {
        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
    }
    uploadData.appendData("\r\n--\(boundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)



    // return URLRequestConvertible and NSData
    return (Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
}    

Berikut adalah contoh cara menggunakannya (lihat BUAT DAN KIRIM PERMINTAAN):

// init paramters Dictionary
var parameters = [
    "task": "task",
    "variable1": "var"
]

// add addtionial parameters
parameters["userId"] = "27"
parameters["body"] = "This is the body text."

// example image data
let image = UIImage(named: "177143.jpg")
let imageData = UIImagePNGRepresentation(image)



// CREATE AND SEND REQUEST ----------

let urlRequest = urlRequestWithComponents("http://example.com/uploadText/", parameters: parameters, imageData: imageData)

Alamofire.upload(urlRequest.0, urlRequest.1)
    .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
        println("\(totalBytesWritten) / \(totalBytesExpectedToWrite)")
    }
    .responseJSON { (request, response, JSON, error) in
        println("REQUEST \(request)")
        println("RESPONSE \(response)")
        println("JSON \(JSON)")
        println("ERROR \(error)")
}    

Dan jika Anda membutuhkan file php untuk url target (dengan folder 'unggah' di direktori yang sama):

// get picture variables
$file       = $_FILES['file']['tmp_name'];
$fileName   = $_FILES['file']['name'];
$fileType   = $_FILES['file']['type'];

// check extension
$allowedExts = array("jpg", "jpeg", "png");
$rootName = reset(explode(".", $fileName));
$extension = end(explode(".", $fileName));

// create new file name
$time = time();
$newName = $rootName.$time.'.'.$extension;

// temporarily save file
$moved = move_uploaded_file($_FILES["file"]["tmp_name"], "uploads/".$newName );
if ($moved) $path = "uploads/".$newName;

$body = $_POST['body'];
$userId = $_POST['userId'];


$time = time();
if ($moved) {
    $fullUrl = "http://antiblank.com/testPhotoUpload/".$path;
    $arrayToSend = array('status'=>'success','time'=>$time,'body'=>$body,'userId'=>$userId, "imageURL"=>$fullUrl);
} else {
    $arrayToSend = array('status'=>'FAILED','time'=>$time,'body'=>$body,'userId'=>$userId);
}

header('Content-Type:application/json');
echo json_encode($arrayToSend);

Unggahan multi-bagian dijadwalkan untuk disertakan dengan rilis Alamofire (1.3.0) berikutnya. Sementara itu, dengan menggunakan informasi di utas ini, saya telah membuat kelas yang menyederhanakan pengunggahan file dan menyertakan parameter tambahan ("input" biasa) dalam permintaan bersama dengan satu atau lebih file. Tanpa berasumsi bahwa file dari jenis tertentu atau penggunaan Router.

FileUploader.swift:

import Foundation
import Alamofire

private struct FileUploadInfo {
  var name:String
  var mimeType:String
  var fileName:String
  var url:NSURL?
  var data:NSData?

  init( name: String, withFileURL url: NSURL, withMimeType mimeType: String? = nil ) {
    self.name = name
    self.url = url
    self.fileName = name
    self.mimeType = "application/octet-stream"
    if mimeType != nil {
      self.mimeType = mimeType!
    }
    if let _name = url.lastPathComponent {
      fileName = _name
    }
    if mimeType == nil, let _extension = url.pathExtension {
      switch _extension.lowercaseString {

      case "jpeg", "jpg":
        self.mimeType = "image/jpeg"

      case "png":
        self.mimeType = "image/png"

      default:
        self.mimeType = "application/octet-stream"
      }
    }
  }

  init( name: String, withData data: NSData, withMimeType mimeType: String ) {
    self.name = name
    self.data = data
    self.fileName = name
    self.mimeType = mimeType
  }
}

class FileUploader {

  private var parameters = [String:String]()
  private var files = [FileUploadInfo]()
  private var headers = [String:String]()

  func setValue( value: String, forParameter parameter: String ) {
    parameters[parameter] = value
  }

  func setValue( value: String, forHeader header: String ) {
    headers[header] = value
  }

  func addParametersFrom( #map: [String:String] ) {
    for (key,value) in map {
      parameters[key] = value
    }
  }

  func addHeadersFrom( #map: [String:String] ) {
    for (key,value) in map {
      headers[key] = value
    }
  }

  func addFileURL( url: NSURL, withName name: String, withMimeType mimeType:String? = nil ) {
    files.append( FileUploadInfo( name: name, withFileURL: url, withMimeType: mimeType ) )
  }

  func addFileData( data: NSData, withName name: String, withMimeType mimeType:String = "application/octet-stream" ) {
    files.append( FileUploadInfo( name: name, withData: data, withMimeType: mimeType ) )
  }

  func uploadFile( request sourceRequest: NSURLRequest ) -> Request? {
    var request = sourceRequest.mutableCopy() as! NSMutableURLRequest
    let boundary = "FileUploader-boundary-\(arc4random())-\(arc4random())"
    request.setValue( "multipart/form-data;boundary=\(boundary)", forHTTPHeaderField: "Content-Type")
    let data = NSMutableData()

    for (name, value) in headers {
      request.setValue(value, forHTTPHeaderField: name)
    }

    // Amazon S3 (probably others) wont take parameters after files, so we put them first        
    for (key, value) in parameters {
      data.appendData("\r\n--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
      data.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
    }

    for fileUploadInfo in files {
      data.appendData( "\r\n--\(boundary)\r\n".dataUsingEncoding(NSUTF8StringEncoding)! )
      data.appendData( "Content-Disposition: form-data; name=\"\(fileUploadInfo.name)\"; filename=\"\(fileUploadInfo.fileName)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

      }
      else { // ToDo: report error
        return nil

    }

    data.appendData("\r\n--\(boundary)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

    return Alamofire.upload( request, data )
  }

}

Ini akan digunakan seperti ini:

// This example uploads a file called example.png found in the app resources

let fileURL = NSBundle.mainBundle().URLForResource("example", withExtension: "png")
let fileUploader = FileUploader()
// we can add multiple files
// this would be equivalent to: <input type="file" name="myFile"/>
fileUploader.addFileURL(fileURL!, withName: "myFile")
// we can add NSData objects directly
let data = UIImage(named: "sample")
fileUploader.addFileData( UIImageJPEGRepresentation(data,0.8), withName: "mySecondFile", withMimeType: "image/jpeg" )
// we can also add multiple aditional parameters
// this would be equivalent to: <input type="hidden" name="folderName" value="sample"/>
fileUploader.setValue( "sample", forParameter: "folderName" )
// put your server URL here
var request = NSMutableURLRequest( URL: NSURL(string: "http://myserver.com/uploadFile" )! )
request.HTTPMethod = "POST"
fileUploader.uploadFile(request: request)

Kode di jawaban @ antiblank tidak berfungsi untuk saya. Saya telah membuat beberapa perubahan dan sekarang berfungsi:

func urlRequestWithComponents(urlString:String, parameters:NSDictionary) -> (URLRequestConvertible, NSData) {

    // create url request to send
    var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
    mutableURLRequest.HTTPMethod = Alamofire.Method.POST.rawValue
    //let boundaryConstant = "myRandomBoundary12345"
    let boundaryConstant = "NET-POST-boundary-\(arc4random())-\(arc4random())"
    let contentType = "multipart/form-data;boundary="+boundaryConstant
    mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")


    // create upload data to send
    let uploadData = NSMutableData()

    // add parameters
    for (key, value) in parameters {

        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

        if value is NetData {
            // add image

            //uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"; filename=\"\(postData.filename)\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

            // append content disposition
            var filenameClause = " filename=\"\(postData.filename)\""
            let contentDispositionString = "Content-Disposition: form-data; name=\"\(key)\";\(filenameClause)\r\n"
            let contentDispositionData = contentDispositionString.dataUsingEncoding(NSUTF8StringEncoding)
            uploadData.appendData(contentDispositionData!)


            // append content type
            //uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!) // mark this. 
            let contentTypeString = "Content-Type: \(postData.mimeType.getString())\r\n\r\n"
            let contentTypeData = contentTypeString.dataUsingEncoding(NSUTF8StringEncoding)
            uploadData.appendData(contentTypeData!)
            uploadData.appendData(postData.data)

        }else{
            uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
        }

    // return URLRequestConvertible and NSData
    return (Alamofire.ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
}

MENGGUNAKAN:

let docDir:AnyObject = NSSearchPathForDirectoriesInDomains(.DocumentDirectory, .UserDomainMask, true)[0]
let imagePath = docDir + "/myPic.jpg"

var imageData = NSData(contentsOfFile: imagePath, options: NSDataReadingOptions.DataReadingMappedIfSafe, error: nil)
var parameters = [
            "pic"           :NetData(nsData: imageData!, filename: "customName.jpg"),
            "otherParm"     :"Value"
        ]


    let urlRequest = self.urlRequestWithComponents("http://www.example.com/upload.php", parameters: parameters)

NetData dari https://github.com/nghialv/Net/blob/master/Net/NetData.swift

Kode upload.php:

<?php
// In PHP versions earlier than 4.1.0, $HTTP_POST_FILES should be used instead
// of $_FILES.

$uploaddir = 'uploads/';
// PS: custom filed name : pic
$uploadfile = $uploaddir . basename($_FILES['pic']['name']);

if (move_uploaded_file($_FILES['pic']['tmp_name'], $uploadfile)) {
   $array = array ("code" => "1", "message" => "successfully");  
} else {
   $array = array ("code" => "0", "message" => "Possible file upload attack!".$_FILES['pic']['name']); 
}

echo json_encode ( $array );

Pemakaian

let rep = (asset as ALAsset).defaultRepresentation()
let ref = rep.fullResolutionImage().takeUnretainedValue()
Photo.upload(UIImage(CGImage: ref)!, filename: rep.filename())
    .progress { (bytesWritten, totalBytesWritten, totalBytesExpectedToWrite) in
        println(totalBytesWritten)
    }
    .responseJSON { (request, response, JSON, error) in
        println(JSON)
    }

Meskipun ada jawaban lain yang menyarankan cara membuat permintaan multi bagian secara manual, Anda mungkin ingin tetap menggunakan AFNetworking. Meskipun ditulis dalam Objective-C, Anda masih bisa menggunakannya di proyek Swift Anda (lihat Swift dan Objective-C di Proyek yang Sama ). Bagaimanapun, kode Swift untuk mengirimkan permintaan multi bagian menggunakan AFNetworking adalah sebagai berikut:

let data = UIImagePNGRepresentation(image)

let manager = AFHTTPSessionManager()

manager.POST(uploadURLString, parameters: nil, constructingBodyWithBlock: { formData in
    formData.appendPartWithFileData(data, name: "image", fileName: "test.png", mimeType: "image/png")
}, success: { operation, responseObject in
    println(responseObject)
}) { operation, error in
    println(error)
}

Xcode mengganggu memiliki masalah mengenali id<AFMultipartFormData>parameter ini formData, jadi Anda tidak menikmati penyelesaian kode editor khas dari appendPartWithFileDatametode atau parameternya, tetapi ketika Anda mengkompilasinya, dan menjalankannya, itu berfungsi dengan baik.

Anda mendapatkan 415 karena kehilangan tipe konten dalam permintaan Anda. Di bawah ini adalah total soution untuk upload gambar di Swift 2 dan AlamoFire

import UIKit
import Alamofire

class ViewController: UIViewController {

@IBOutlet var imageView: UIImageView!
@IBOutlet var btnUpload: UIButton!
override func viewDidLoad() {
    super.viewDidLoad()
}

func successDataHandler(responseData:String){

Di bawah ini adalah Swift dan Kode Php

Kode Swift -> Apple Swift versi 3.0.1 (swiftlang-800.0.58.6 clang-800.0.42.1) Target: x86_64-apple-macosx10.9

   class  func upload(jsonObject: AnyObject , files : Array<Any>? = nil  , completionHandler :  CompletionBlock? = nil ,failureHandler : FailureBlock? = nil )
{

    Alamofire.upload(multipartFormData:
        { (multipartFormData) in

            if let  filesO = files
            {
                for i in (filesO.enumerated())
                {
                    let image = UIImage(named: "\(i.element)")

                    let data = UIImageJPEGRepresentation(image!, 1)!

                    multipartFormData.append(data, withName: "imgFiles[]" , fileName: "\( NSUUID().uuidString).jpeg" , mimeType: "image/jpeg")
                  // imgFiles[] give array in Php Side
                  // imgFiles   will give string in PHP String


                }

            }


            for  (key, value)  in jsonObject as! [String : String]
            {

                 multipartFormData.append(value.data(using: String.Encoding.utf8)!, withName: key)

            }}          
    },
                     to:baseURL)

Kode PHP untuk Mendapatkan Parameter dan File

Berikut Parameter Ditangani dalam $ _Request

Dan File ditangani di $ _File

Format dalam $ _File data (Array, Dictionary atau String) akan bergantung pada Request in swift side, Disini Lihat baris ini dalam kode

multipartFormData.append (data, withName: "imgFiles []", fileName: "(NSUUID (). uuidString) .jpeg", mimeType: "image / jpeg")

di sisi Php withName: "imgFiles []" memberikan array nama, format, Type

Misalnya

"name": ["06748B86-478E-421B-8470-6262755AC149.jpeg", "E70269E9-FB54-4BFD-B807-7E418C81540D.jpeg"], "type": ["image / jpeg", "image / jpeg" ], "tmp_name": ["/ tmp / phpz3UAPq", "/ tmp / phpCAPExG"], "error": [0,0], "size": [2779495,2067259]}

Kode PHP

 if (isset($_FILES['imgFiles']) and strlen($orderId) > 0) {

        foreach ($_FILES['imgFiles']['tmp_name'] as $key => $tmp_name) {

            $file_name = $key . $_FILES['imgFiles']['name'][$key];
            $file_size = $_FILES['imgFiles']['size'][$key];
            $file_tmp = $_FILES['imgFiles']['tmp_name'][$key];
            $file_type = $_FILES['imgFiles']['type'][$key];
 if (is_dir("$desired_dir/" . $file_name) == false) {
                //move_uploaded_file($file_tmp, "user_data/" . $file_name);
                move_uploaded_file($file_tmp, $desired_dir . "/" .
           $file_name);
            } else {         //rename the file if another one exist
                $new_dir = $desired_dir . "/" . $file_name . time();
                rename($file_tmp, $new_dir);
            }

Saya mengambil jawaban antiblank dan membungkus ini semua menjadi 1 fungsi dengan penangan penyelesaian. Pikir itu mungkin berguna untuk seseorang. Ini sedikit 'lebih kasar' daripada jawaban antiblank karena saya hanya mengambil respons string dari file PHP (bukan JSON).

Begini cara Anda menyebutnya:

let imageData = UIImagePNGRepresentation(myImageView.image)

uploadImage("http://www.example.com/image_upload.php", imageData: imageData, subdir: "images", filename: "imageID.png")
    { (req, res, str, err) -> Void in
        // do whatever you want to to for error handling and handeling success
    }

Berikut fungsinya sendiri:

func uploadImage(urlToPHPFile: String, imageData: NSData, subdir: String, filename: String, completionHandler:(request:NSURLRequest, response:NSURLResponse?, responseString:String?, error: NSError?) -> ()) {

    func urlRequestWithComponents(urlString:String, parameters:Dictionary<String, String>, imageData:NSData) -> (URLRequestConvertible, NSData) {
        // create url request to send
        var mutableURLRequest = NSMutableURLRequest(URL: NSURL(string: urlString)!)
        mutableURLRequest.HTTPMethod = Method.POST.rawValue
        let boundaryConstant = "myRandomBoundary12345";
        let contentType = "multipart/form-data;boundary="+boundaryConstant
        mutableURLRequest.setValue(contentType, forHTTPHeaderField: "Content-Type")

        // create upload data to send
        let uploadData = NSMutableData()

        // add image
        uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Disposition: form-data; name=\"file\"; filename=\"file.png\"\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData("Content-Type: image/png\r\n\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
        uploadData.appendData(imageData)

        // add parameters
        for (key, value) in parameters {
            uploadData.appendData("\r\n--\(boundaryConstant)\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)
            uploadData.appendData("Content-Disposition: form-data; name=\"\(key)\"\r\n\r\n\(value)".dataUsingEncoding(NSUTF8StringEncoding)!)
        }
        uploadData.appendData("\r\n--\(boundaryConstant)--\r\n".dataUsingEncoding(NSUTF8StringEncoding)!)

        // return URLRequestConvertible and NSData
        return (ParameterEncoding.URL.encode(mutableURLRequest, parameters: nil).0, uploadData)
    }

    let parameters = [
        "subdir" : subdir,
        "filename": filename
    ]
    let urlRequest = urlRequestWithComponents(urlToPHPFile, parameters, imageData)

    AlamoFire.upload(urlRequest.0, urlRequest.1)
        .responseString(completionHandler: { [weak self] (req, res, str, err) -> Void in
            if let strongSelf = self {
                completionHandler(request: req, response: res, responseString: str, error: err)

            }
        }
    )
}

Dan ini file phpnya.

$subdir = $_POST['subdir'];
$filename = $_POST["filename"];

$targetPath = $subdir.'/'.$filename;

$moved = move_uploaded_file($_FILES["file"]["tmp_name"], $targetPath );
if ($moved) {
    echo "OK";
}
else {
    echo "Error: file not uploaded";
}
