HTTP post en Java ne publie pas côté serveur [dupliquer]

Cette question a déjà des réponses ici: Comment utiliser java. net. URLConnection pour déclencher et gérer les requêtes HTTP? (11 réponses) Fermé il y a 5 ans.

J'essaie de publier des données en utilisant HTTP post mais je ne vois pas les données à l'autre extrémité (serveur). Lorsque j'exécute le programme, je reçois un code de réponse 200 (succès) mais lorsque je vérifie par recoupement, aucune donnée n'est trouvée à l'autre extrémité

private void sendPost() throws Exception {

    String url = "https://example.com/post/index.php";
    URL obj = new URL(url);

    HttpsURLConnection con = (HttpsURLConnection)obj.openConnection();


    //add reuqest header
    con.setRequestMethod("POST");
    con.setRequestProperty("User-Agent", USER_AGENT);
    con.setRequestProperty("charset", "utf-8");



    String urlParameters = "username=userpv&password=pvpwd&admin_username=&admin_password=&action=add&requisition_number=403555&return_url=&error_url=www.some.com&error_format=1";

    // urlParameters string is very long

    con.setDoOutput(true);
    DataOutputStream wr = new DataOutputStream(con.getOutputStream());
    wr.writeBytes(urlParameters);
    wr.flush();
    wr.close();

    int responseCode = con.getResponseCode();
    System.out.println("\nSending 'POST' request to URL : " + url);
    System.out.println("Post parameters : " + urlParameters);
    System.out.println("Response Code : " + responseCode);

    BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));


    String inputLine;
    StringBuffer response = new StringBuffer();

    while ((inputLine = in.readLine()) != null) {
        System.out.println(inputLine);
    }
    in.close();

    //print result
    //System.out.println(response.toString());

}

Quelqu'un peut-il me dire ce qui ne va pas avec mon code?

J'ai testé votre code avec cette url 'https://posttestserver.com/post.php?dir=example " et cela semble ok. Êtes-vous sûr que le problème n'est pas du côté du serveur?

   public static void main (String[] args) throws IOException {

      String url = "https://posttestserver.com/post.php?dir=example";
      URL obj = new URL(url);

      HttpsURLConnection con = (HttpsURLConnection)obj.openConnection();

      //add reuqest header
      con.setRequestMethod("POST");
      con.setRequestProperty("User-Agent", "AGENT");
      con.setRequestProperty("charset", "utf-8");     

      String urlParameters = "username=userpv&password=pvpwd&admin_username=&admin_password=&action=add&requisition_number=403555&return_url=&error_url=www.some.com&error_format=1";

      // urlParameters string is very long

      con.setDoOutput(true);
      DataOutputStream wr = new DataOutputStream(con.getOutputStream());
      wr.writeBytes(urlParameters);
      wr.flush();
      wr.close();

      int responseCode = con.getResponseCode();
      System.out.println("\nSending 'POST' request to URL : " + url);
      System.out.println("Post parameters : " + urlParameters);
      System.out.println("Response Code : " + responseCode);

      BufferedReader in = new BufferedReader(new InputStreamReader(con.getInputStream()));

      String inputLine;
      StringBuffer response = new StringBuffer();

      while ((inputLine = in.readLine()) != null) {
          System.out.println(inputLine);
      }
      in.close();

      //print result
      //System.out.println(response.toString());      
   }
