java - 获取 com.android.volley.ServerError

Question

使用 volley 的 PUT 请求

Log.i("JsonObject is",finaljsonData.toString());Output:-{"stats":[{"med_id":1,"med_name":"Evening","start_date":1476107306168,"end_date":1476193706168,"adherence":{"taken_on":[1476107704867],"missed_on":[]}}]}

Code:

    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

您要作为字符串发送的 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 postman 中您从那里发送的 header 是否与您从应用程序发送的 header 相同。
