android - BasicNetwork.performRequest : Unexpected response code 500 for http://192. 168.1.195:85/tranxavApi/public/api/signup

Question

也许这个问题之前已经发布过，但它并没有解决我的问题。我正在尝试使用 laravel 作为后端将数据从 android 发送到 mysql 数据库。我开发了restful Api。这是我的代码。

         try {
                RequestQueue requestQueue = Volley.newRequestQueue(SignUpActivity.this);

                JSONObject jsonBody = new JSONObject();
                jsonBody.put("username","amz");
                jsonBody.put("email","amz@gmail.com");
                jsonBody.put("password","fashion");
                jsonBody.put("vCode","12345");
                jsonBody.put("type","coupons");
                final String requestBody = jsonBody.toString();

                StringRequest stringRequest = new StringRequest(Request.Method.POST, url, new Response.Listener<String>() {
                    @Override
                    public void onResponse(String response) {
                        Log.i("VOLLEY", response);
                    }
                }, new Response.ErrorListener() {
                    @Override
                    public void onErrorResponse(VolleyError error) {
                        Log.e("VOLLEY", error.toString());
                    }
                }) {
                    @Override
                    public String getBodyContentType() {
                        return "application/json; charset=utf-8";
                    }

                    @Override
                    public byte[] getBody() throws AuthFailureError {
                        try {
                            return requestBody == null ? null : requestBody.getBytes("utf-8");
                        } catch (UnsupportedEncodingException uee) {
                            VolleyLog.wtf("Unsupported Encoding while trying to get the bytes of %s using %s", requestBody, "utf-8");
                            return null;
                        } catch (Exception e) {
                            e.printStackTrace();
                            return null;
                        }
                    }
                    @Override
                    protected Response<String> parseNetworkResponse(NetworkResponse response) {
                        String responseString = "";
                        if (response != null) {
                            responseString = String.valueOf(response.statusCode);
                            // can get more details such as response.headers
                        }
                        return Response.success(responseString, HttpHeaderParser.parseCacheHeaders(response));
                    }
                };
                requestQueue.add(stringRequest);
            } catch (JSONException e) {
                e.printStackTrace();
            }

Laravel 代码

 public function signUp(Request $request){
    $success = "Successful";
    $validator = Validator::make($request->all(), [
        'email' => 'required|email|max:255|unique:users',
        'password' => 'required|min:5'
    ]);

    if ($validator->fails()){
        return response()->json(['error'=>$validator->errors()], 401);
    }
    User::create([
        'email' => $request->get('email'),
        'username' => $request->get('username'),
        'password' => Hash::make($request->get('password')),
        'vCode' => $request->get('vCode')
    ]);

    return response()->json(['success'=> $success], $this->successStatus);
}

将此添加到您的代码中

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

                return params;  
        }
    };
