錯誤Volley庫com.android.volley.ParseError：org.json.JSONException：

Question

我嘗試使用Volley Library發出PUT請求。 我已經獲得了請求，並使用了覆蓋方法getParam（）來放置請求，但是對於此請求，我需要發送我之前創建的jsonOjbect。

但是在響應中，我有：

08-25 09:44:34.638: I/ViewPdf:  SaveDataToProxy ERROR(8512): 
error: com.android.volley.ParseError: org.json.JSONException: Value <br of type 
java.lang.String cannot be converted to JSONObject

這是我的方法連接：

public void SaveDataToProxy(JSONObject jsonObject){

    // Tag used to cancel the request
    String tag_json_obj = "json_obj_req";

    String url = Properties.getUrl_proxy() + ":" + Properties.getPort_proxy() +"/api/points/"+this.id_point;
    Log.i("url",url); 

    final ProgressDialog pDialog = new ProgressDialog(this);
    pDialog.setMessage("Loading...");
    pDialog.show(); 

    JsonObjectRequest jsObjRequest = new JsonObjectRequest
    (
            Request.Method.PUT, url, jsonObject, new Response.Listener<JSONObject>()
            {
                @Override
                public void onResponse(JSONObject response)
                {
                        Log.i(TAG + ":  SaveDataToProxy SUCCESS", "response: " + response);
                }

            }, new Response.ErrorListener() 
            {
                @Override
                public void onErrorResponse(VolleyError error) 
                {
                    Log.i(TAG + ":  SaveDataToProxy ERROR", "error: " + error);
                }
             }
    )

    {
        @Override
        public Map<String, String> getHeaders() throws AuthFailureError 
        {
            HashMap<String, String> headers = new HashMap<String, String>();
            headers.put("Content-type", "application/json");

            return headers;
        }
    };

    AppController.getInstance().addToRequestQueue(jsObjRequest, tag_json_obj); 
}

這是我發送的JSONObject.toString（）：

    null

我希望你能幫助我=）

編輯1：這是我的完整堆棧跟蹤，我們只能看到連接，而沒有什么很重要的...

這不是您的問題，這是服務器端的問題，服務器不會向您返回有效的json 。 它實際上會返回您的html代碼，以查看其返回的確切內容，只需為瀏覽器安裝add on，例如RESTClient for mozilla並將您的請求按相應的類型（post-get -...）發送到服務器，然后查看服務器結果。
