envoyer la valeur d'en-tête à l'aide de HttpUrlConnection

Question

J'ai essayé d'envoyer une réponse au serveur en utilisant la valeur d'authentification, qui me le fournit au moment de la connexion. Le serveur accepte uniquement les demandes lorsque cette valeur est envoyée. Cependant, cela fonctionne bien avec postman (see snapshot) mais pas avec mon code.

Code

URL url = new URL(strings[0]); 
      HttpURLConnection con = (HttpURLConnection) url.openConnection(); 
      String token = "" + new String(accessToken); 
      con.setRequestMethod("GET"); 
      con.setRequestProperty("AuthToken", token); 
      con.setReadTimeout(15000); 
      con.setConnectTimeout(15000); 
      con.setDoOutput(false); 

J'ai aussi essayé de cette façon

String token = "AuthToken :" + new String(accessToken); 
con.setRequestProperty("Authorization", token); 

Answer 1

Essayez celui

URL url = new URL(strings[0]); 
     HttpURLConnection con = (HttpURLConnection) url.openConnection(); 
     String token = "" + new String(accessToken); 
     con.setRequestMethod("GET"); 
     con.setRequestProperty("AuthToken", token); 
     con.setReadTimeout(15000); 
     con.setConnectTimeout(15000); 
     con.setDoOutput(false); 

Answer 2

Essayez de cette façon ..

String token = new String(new Base64().encode(accessToken.getBytes())); 
con.setRequestProperty("AuthToken", token); 

Answer 3

Essayez de remplacer myURLConnection.setRequestMethod ("GET"); avec myURLConnection.setRequestProperty ("Request Method", "GET");

S'il vous plaît trouver le code ci-dessous:

URL myURL = new URL(serviceURL); 
HttpURLConnection myURLConnection = (HttpURLConnection)myURL.openConnection(); 
String userCredentials = "username:password"; 
String basicAuth = "Basic " + new String(new Base64().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);
