java - 错误 Volley 库 com.android.volley.ParseError : org. json.JSONException:

Question

我尝试使用 Volley 库发出 PUT 请求。我已经使用 g Override 方法 getParam() 获取请求并发出请求，但对于此请求，我需要发送我之前创建的 jsonOjbect。

但在我的回复中:

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

所以这是我的方法连接:

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); 
}

这是我发送的 JSONObject.toString() :

    null

    null

我希望你能帮助我 =)

这不是你的问题，这是服务器端的问题，服务器没有返回有效的 json 给你。它实际上返回给您 html 代码，为了查看它返回的确切内容，只需为浏览器安装插件，例如 mozilla 的 RESTClient 并发送您的通过相应类型(post-get-...)向服务器请求，然后查看服务器结果。
