发送表单urlen codeD参数POST请求的Andr​​oid凌空抽射 [英] Send form-urlencoded parameters in post request android volley

问题描述

我想打一个POST JSONObjectRequest与形式urlen codeD参数。我怎样才能做到这一点？我试过以下code，但无济于事。

I want to make a POST JSONObjectRequest with form urlencoded parameters. How can I do this? I've tried the following code, but to no avail.

final String api = "http://api.url";
final JSONObject jobj = new JSONObject();
jobj.put("Username", "usr");
jobj.put("Password", "passwd");
jobj.put("grant_type", "password");

final JsonObjectRequest jor = new JsonObjectRequest(Request.Method.POST, api, jobj, new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    Toast.makeText(getApplicationContext(), "Login Successful!", Toast.LENGTH_LONG).show();
  //do other things with the received JSONObject
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    Toast.makeText(getApplicationContext(), "Error!", Toast.LENGTH_LONG).show();
               }
            }) {
                @Override
                public Map<String, String> getHeaders() throws AuthFailureError {
                    Map<String, String> pars = new HashMap<String, String>();
                    pars.put("Content-Type", "application/x-www-form-urlencoded");
                    return pars;
                }
            };
  //add to the request queue
  requestqueue.AddToRequestQueue(jor);

我得到的API调用400错误的请求！我怎样才能解决这个问题？

I'm getting a 400 bad request with the api call! How can I fix it?

推荐答案

亚特很长很长的斗争，找到了解决办法。你需要重写getBodyContentType（），并返回应用程序/ x-WWW的形式urlen codeD;字符集= UTF-8;

Ater a long long struggle, found the solution. You need to override getBodyContentType() and return "application/x-www-form-urlencoded; charset=UTF-8";

StringRequest jsonObjRequest = new StringRequest(Request.Method.POST,
            getResources().getString(R.string.base_url),
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {

                    MyFunctions.toastShort(LoginActivity.this, response);
                }
            }, new Response.ErrorListener() {

                @Override
                public void onErrorResponse(VolleyError error) {
                    VolleyLog.d("volley", "Error: " + error.getMessage());
                    error.printStackTrace();
                    MyFunctions.croutonAlert(LoginActivity.this,
                            MyFunctions.parseVolleyError(error));
                    loading.setVisibility(View.GONE);
                }
            }) {

        @Override
        public String getBodyContentType() {
            return "application/x-www-form-urlencoded; charset=UTF-8";
        }

        @Override
        protected Map<String, String> getParams() throws AuthFailureError {
            Map<String, String> params = new HashMap<String, String>();
            params.put("username", etUname.getText().toString().trim());
            params.put("password", etPass.getText().toString().trim());
            return params;
        }

    };

    AppController.getInstance().addToRequestQueue(jsonObjRequest);
