Menambahkan header untuk HttpURLConnection

Saya mencoba menambahkan header untuk permintaan saya menggunakan HttpUrlConnectiontetapi metode setRequestProperty()ini tampaknya tidak berfungsi. Sisi server tidak menerima permintaan apa pun dengan tajuk saya.

HttpURLConnection hc;
    try {
        String authorization = "";
        URL address = new URL(url);
        hc = (HttpURLConnection) address.openConnection();


        hc.setDoOutput(true);
        hc.setDoInput(true);
        hc.setUseCaches(false);

        if (username != null && password != null) {
            authorization = username + ":" + password;
        }

        if (authorization != null) {
            byte[] encodedBytes;
            encodedBytes = Base64.encode(authorization.getBytes(), 0);
            authorization = "Basic " + encodedBytes;
            hc.setRequestProperty("Authorization", authorization);
        }

Saya telah menggunakan kode berikut di masa lalu dan itu berhasil dengan otentikasi dasar yang diaktifkan di TomCat:

URL myURL = new URL(serviceURL);
HttpURLConnection myURLConnection = (HttpURLConnection)myURL.openConnection();

String userCredentials = "username:password";
String basicAuth = "Basic " + new String(Base64.getEncoder().encode(userCredentials.getBytes()));

myURLConnection.setRequestProperty ("Authorization", basicAuth);
myURLConnection.setRequestMethod("POST");
myURLConnection.setRequestProperty("Content-Type", "application/x-www-form-urlencoded");
myURLConnection.setRequestProperty("Content-Length", "" + postData.getBytes().length);
myURLConnection.setRequestProperty("Content-Language", "en-US");
myURLConnection.setUseCaches(false);
myURLConnection.setDoInput(true);
myURLConnection.setDoOutput(true);

Anda dapat mencoba kode di atas. Kode di atas adalah untuk POST, dan Anda dapat memodifikasinya untuk GET

Hanya karena saya tidak melihat sedikit informasi ini di jawaban di atas, alasan cuplikan kode yang semula diposting tidak berfungsi dengan benar adalah karena encodedBytesvariabelnya adalah a byte[]dan bukan Stringnilai. Jika Anda meneruskan byte[]ke a new String()seperti di bawah ini, cuplikan kode berfungsi dengan baik.

encodedBytes = Base64.encode(authorization.getBytes(), 0);
authorization = "Basic " + new String(encodedBytes);

Jika Anda menggunakan Java 8, gunakan kode di bawah ini.

URLConnection connection = url.openConnection();
HttpURLConnection httpConn = (HttpURLConnection) connection;

String basicAuth = Base64.getEncoder().encodeToString((username+":"+password).getBytes(StandardCharsets.UTF_8));
httpConn.setRequestProperty ("Authorization", "Basic "+basicAuth);

Akhirnya ini berhasil bagi saya

private String buildBasicAuthorizationString(String username, String password) {

    String credentials = username + ":" + password;
    return "Basic " + new String(Base64.encode(credentials.getBytes(), Base64.DEFAULT));
}

Kode Anda baik-baik saja. Anda juga dapat menggunakan hal yang sama dengan cara ini.

public static String getResponseFromJsonURL(String url) {
    String jsonResponse = null;
    if (CommonUtility.isNotEmpty(url)) {
        try {
            /************** For getting response from HTTP URL start ***************/
            URL object = new URL(url);

            HttpURLConnection connection = (HttpURLConnection) object
                    .openConnection();
            // int timeOut = connection.getReadTimeout();
            connection.setReadTimeout(60 * 1000);
            connection.setConnectTimeout(60 * 1000);
            String authorization="xyz:xyz$123";
            String encodedAuth="Basic "+Base64.encode(authorization.getBytes());
            connection.setRequestProperty("Authorization", encodedAuth);
            int responseCode = connection.getResponseCode();
            //String responseMsg = connection.getResponseMessage();

            if (responseCode == 200) {
                InputStream inputStr = connection.getInputStream();
                String encoding = connection.getContentEncoding() == null ? "UTF-8"
                        : connection.getContentEncoding();
                jsonResponse = IOUtils.toString(inputStr, encoding);
                /************** For getting response from HTTP URL end ***************/

            }
        } catch (Exception e) {
            e.printStackTrace();

        }
    }
    return jsonResponse;
}

Pengembalian kode respon 200 jika otorisasi berhasil

Dengan RestAssurd Anda juga dapat melakukan hal berikut:

String path = baseApiUrl; //This is the base url of the API tested
    URL url = new URL(path);
    given(). //Rest Assured syntax 
            contentType("application/json"). //API content type
            given().header("headerName", "headerValue"). //Some API contains headers to run with the API 
            when().
            get(url).
            then().
            statusCode(200); //Assert that the response is 200 - OK

Langkah 1: Dapatkan objek HttpURLConnection

URL url = new URL(urlToConnect);
HttpURLConnection httpUrlConnection = (HttpURLConnection) url.openConnection();

Langkah 2: Tambahkan header ke HttpURLConnection menggunakan metode setRequestProperty.

Map<String, String> headers = new HashMap<>();

headers.put("X-CSRF-Token", "fetch");
headers.put("content-type", "application/json");

for (String headerKey : headers.keySet()) {
    httpUrlConnection.setRequestProperty(headerKey, headers.get(headerKey));
}
