Question

Sto usando i componenti Httpclient-4.5.2.jar e httpcore-4.4.4.jar HttpClient e sto ricevendo l'errore.

Exception in thread "main" java.lang.NoSuchFieldError: INSTANCE 
at org.apache.http.conn.ssl.SSLConnectionSocketFactory.<clinit>(SSLConnectionSocketFactory.java:144) 
at org.apache.http.impl.client.HttpClientBuilder.build(HttpClientBuilder.java:966) 

Il mio codice sorgente come segue.

try { 
     System.out.println("came to try catch"); 
     HttpClient httpClient = HttpClientBuilder.create().build(); 
     HttpPost request = new HttpPost("https://bizz.mobilezz.lk/apicall/loanprepaidapi/v1"); 
     StringEntity params =new StringEntity("{\"mobile\":\"776037285\",\"path\":\"IVV\",\"loanAmount\":\"200000\"}"); 
     request.addHeader("content-type", "application/json"); 
     request.addHeader("Authorization", "Bearer casmk34233mlacscmaacsac"); 

     request.addHeader("Accept", "application/json");   
     request.setEntity(params); 
     HttpResponse response = httpClient.execute(request); 
     System.out.println("response is :"+response.getStatusLine()); 

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

Please help me per sbarazzarsi di questo errore. Sto cercando di inviare la richiesta in modalità post e ottenere una risposta JSON.

Ho trovato una risposta alla mia domanda e la pubblicazione per il vostro riferimento.

HttpClient client = new DefaultHttpClient(); 
     HttpPost post = new HttpPost(
       "https://bizz.mobilezz.lk/apicall/loanprepaidapi/v1"); 

     JSONObject json = new JSONObject(); 
     StringEntity params = new StringEntity("{\"msisdn\":\"" + mobile 
       + "\",\"channel\":\"SDD\"}"); 

     new StringEntity(json.toString()); 
     post.addHeader("Host", "mife.dialog.lk"); 
     post.addHeader("content-type", "application/json"); 
     post.addHeader("Authorization", "Bearer " + access_token); 
     post.addHeader("Accept", "application/json"); 

     // System.out.println("status code is:" + status); 
     post.setEntity(params); 
     HttpResponse response = client.execute(post); 
     int status = response.getStatusLine().getStatusCode(); 
     System.out.println("status code is :" + status); 
     resCode = Integer.toString(status); 
     if (status != 401) { 
      if (status != 409) { 
       BufferedReader rd = new BufferedReader(
         new InputStreamReader(response.getEntity() 
           .getContent())); 
       String response1 = readAll(rd); 
       System.out.println(response1); 
       JSONObject obj = new JSONObject(response1); 
       resCode = obj.getString("resCode"); 
       resDesc = obj.getString("resDesc"); 
       System.out.println(resCode); 
       System.out.println(resDesc); 
      } 
     } 
     System.out.println("reason code is :" + resCode);
