Volley使用POST方法将JSONObject发送到服务器

您可以使用以下工作示例代码。我测试过了 希望这可以帮助！

       try { jsonBody = new JSonObject(); jsonBody.put("Title", "VolleyApp Android Demo"); jsonBody.put("Author", "BNK"); jsonBody.put("Date", "2015/08/26"); requestBody = jsonBody.toString(); StringRequest stringRequest = new StringRequest(1, url, new Response.Listener<String>() {     @Override     public void onResponse(String response) {         textView.setText(response);     } }, new Response.ErrorListener() {     @Override     public void onErrorResponse(VolleyError error) {         textView.setText(error.toString());     } }) {     @Override     public String getBodyContentType() {         return String.format("application/json; charset=utf-8");     }     @Override     public byte[] getBody() throws AuthFailureError {         try {  return requestBody == null ? null : requestBody.getBytes("utf-8");         } catch (UnsupportedEncodingException uee) {  VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s",          requestBody, "utf-8");  return null;         }     } }; MySingleton.getInstance(this).addToRequestQueue(stringRequest);        } catch (JSonException e) { e.printStackTrace();        }

更新： 要创建JSONObject作为您的要求，请使用以下命令：

        JSonObject jsonObject = new JSonObject();        try { jsonObject.put("11", 3); jsonObject.put("12", 4); jsonObject.put("13", 5); JSonObject jsonObject2 = new JSonObject().put("answers", jsonObject); jsonObject2.put("user_id", 12);         } catch (JSonException e) { e.printStackTrace();        }
