获取 com.android.volley.ServerError

Question

使用 Volley 进行 PUT 请求

Log.i("JsonObject 是",finaljsonData.toString());
输出：-

{“stats”：[{“med_id”：1，“med_name”：“晚上”，“start_date”：1476107306168，“end_date”：1476193706168，“坚持”：{“taken_on”：[1476107704867]，“missed_on”： []}}]}

代码：

    JsonObjectHeader customRequest=new JsonObjectHeader(Request.Method.PUT,url, finaljsonData, listener, errorListener);
    RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext());
    requestQueue.add(customRequest);

JsonObjectHeader 类是：-

public class JsonObjectHeader extends JsonRequest<JSONObject> {

    public JsonObjectHeader(int method, String url, String requestBody, Response.Listener<JSONObject> listener, Response.ErrorListener errorListener) {
        super(method, url, requestBody, listener, errorListener);
    }

    public JsonObjectHeader(String url, JSONObject jsonRequest, Response.Listener<JSONObject> listener,
                            Response.ErrorListener errorListener) {
        this(jsonRequest == null ? Method.GET : Method.POST, url, jsonRequest,
                listener, errorListener);
    }

    public JsonObjectHeader(int method, String url, JSONObject jsonRequest,
                            Response.Listener<JSONObject> listener, Response.ErrorListener errorListener) {
        super(method, url, (jsonRequest == null) ? null : jsonRequest.toString(), listener,
                errorListener);
    }

    @Override
    protected Response<JSONObject> parseNetworkResponse(NetworkResponse response) {

        try {
            Log.i("Response parse","Yes");
            String jsonString = new String(response.data,
                    HttpHeaderParser.parseCharset(response.headers));
            Log.i("Json String",jsonString);
            Log.i("Response Complete",response.toString());
            Log.i("Response Data",response.data.toString());
            return Response.success(new JSONObject(jsonString),
                    HttpHeaderParser.parseCacheHeaders(response));
        } catch (UnsupportedEncodingException e) {
            return Response.error(new ParseError(e));
        } catch (JSONException je) {
            return Response.error(new ParseError(je));
        }

    }

    @Override
    public Map<String, String> getHeaders() throws AuthFailureError {
        HashMap<String, String> headers = new HashMap<String, String>();
        headers.put("Content-Type", "application/json; charset=utf-8");
        headers.put("x-access-token", Constants.getTokenDB());
        return headers;

    }

}

LogCat 输出：

我尝试过使用PostMan。所以它工作正常：所以我认为没有服务器错误

Answer 1

您以字符串形式发送的 json 正文，请尝试将其作为 json 对象发送。服务器可能需要一个 json 对象。否则，标题值可能会出现问题。检查邮递员您从那里发送的标头是否与您从应用程序发送的标头相同。
