使用Volley发送POST参数和标题时的代码响应代码400

我已经尝试了每种方法都可用于stackoverflow但结果保持不变。使用Volley发送POST参数和标题时的代码响应代码400

I want to send params and also api key in the Authorization field of header using volley.

这是代码片段。

holder.comment_button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(View view) { 
      String POSTCOMMENT_URL = Utility.getIPADDRESS()+"comments"; 
      volleySingleton = VolleySingleton.getInstance(); 
      requestQueue = volleySingleton.getRequestQueue(); 
      JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, POSTCOMMENT_URL, null, new Response.Listener<JSONObject>() { 
       @Override 
       public void onResponse(JSONObject response) { 
        Log.e("Response: " , response.toString()); 
        Toast.makeText(myApplication.getApplicationContext(),response.toString(),Toast.LENGTH_LONG).show(); 
       } 
      }, new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError error) { 
        Toast.makeText(myApplication.getApplicationContext(),"Error", Toast.LENGTH_LONG).show(); 
       } 
      }){ 
       @Override 
       public String getBodyContentType() { 
        return "application/x-www-form-urlencoded; charset=UTF-8"; 
       } 
       @Override 
       public Map<String, String> getHeaders() throws AuthFailureError { 
        Map<String, String> params = new HashMap<>(); 
        params.put("Authorization", getApiKey()); 
        return params; 
       } 

       @Override 
       protected Map<String, String> getParams() { 
        Map<String, String> params = new HashMap<>(); 
        params.put("pid", "39"); 
        params.put("comment", "mobile testing"); 
        return params; 
       } 

      }; 
      requestQueue.add(jsonObjectRequest); 
     } 
    });

我得到这个错误：

[5333] BasicNetwork.performRequest: Unexpected response code 400 for http://www.XXXXXXXXXXX.com/comments

我已经测试使用先进的REST客户端的端点，它的工作原理，并与先前添加的注释返回的JSONObject。

下面是结果：

{ 
"error": false 
"message": "comment added successfully added!" 
"comment_id": "12" 
"user_id": "12" 
"pid": "39" 
"comment": "testing for stackoverflow" 
"date of comment": "2016-07-30 13:49:08" 
}

400是什么意思？ – greenapps

由于格式错误，服务器无法理解请求。总之_Bad网络request_。 –

'String POSTCOMMENT_URL = Utility.getIPADDRESS（）+“comments”;'。那应该是'String POSTCOMMENT_URL = Utility.getIPADDRESS（）+“/ comments”;'？如果不是，那么函数名称会令人困惑。 – greenapps

好，经过长期的研究和愚蠢而宝贵的变化之后，它终于为我工作。

这里是工作代码：

holder.comment_button.setOnClickListener(new View.OnClickListener() { 
     @Override 
     public void onClick(final View view) { 

      final String api_key = getApiKey(); 
      String POSTCOMMENT_URL = Utility.getIPADDRESS()+"comments"; 
      volleySingleton = VolleySingleton.getInstance(); 
      requestQueue = volleySingleton.getRequestQueue(); 
      StringRequest stringRequest = new StringRequest(Request.Method.POST, POSTCOMMENT_URL, new Response.Listener<String>() { 
       @Override 
       public void onResponse(String response) { 
        Toast.makeText(myApplication.getApplicationContext(),response,Toast.LENGTH_LONG).show(); 
       } 
      }, new Response.ErrorListener() { 
       @Override 
       public void onErrorResponse(VolleyError error) { 
        Toast.makeText(myApplication.getApplicationContext(),error.toString(),Toast.LENGTH_LONG).show(); 
       } 
      }) { 

       @Override 
       public Map<String, String> getHeaders() throws AuthFailureError { 
        Map<String, String> params = new HashMap<>(); 
        params.put("Authorization", api_key); 
        return params; 
       } 

       @Override 
       protected Map<String, String> getParams() { 
        Map<String, String> params = new HashMap<>(); 
        params.put("pid", "40"); 
        params.put("comment", "testing"); 
        return params; 
       } 

      }; 
      requestQueue.add(stringRequest); 
     } 
    });

Note: It worked for me, I'm not sure about others.

的变化是：更改JsonObjectRequest到StringRequest和删除任何内容类型不作任何区别，所以我删除它。

Also, make sure all the params have some values i.e test it by logging.
