java - 使用JSON和 Volley 发送数据

我正在尝试使用Volley和JSON将数据发送到Web服务，但是我不知道如何将数据正确地放入我的字符串请求中



我的代码

String url = "http://api.jasamedika.co.id/service/pegawai/1200034";

    final ProgressDialog loading = ProgressDialog.show(getContext(), "Uploading...", "Please wait...", false, false);
    StringRequest stringRequest = new StringRequest(Request.Method.POST, url,
            new Response.Listener<String>() {
                @Override
                public void onResponse(String response) {
                    Log.e(TAG, "Response: " + response.toString());

                    try {
                        JSONObject jObj = new JSONObject(response);
                        succes = jObj.getInt(TAG_SUCCESS);

                        if (succes == 1) {
                            Toast.makeText(getContext(), jObj.getString(TAG_MESSAGE), Toast.LENGTH_LONG).show();
                            //kosong();
                        } else {
                            Toast.makeText(getContext(), jObj.getString(TAG_MESSAGE), Toast.LENGTH_LONG).show();
                        }
                    } catch (JSONException e) {
                        e.printStackTrace();
                    }
                    //menghilangkan progress dialog
                    loading.dismiss();
                }
            },
            new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    //menghilangkan progress dialog
                    loading.dismiss();
                    //menampilkan toast
                    Toast.makeText(getContext(), error.toString(), Toast.LENGTH_LONG).show();
                    Log.e(TAG, error.getMessage().toString());
                }
            }) {
        @Override
        protected Map<String, String> getParams() {
            //membuat parameters
            Map<String, String> params = new HashMap<String, String>();
            //menambah parameter yang di kirim ke web servis
            params.put("Content-Type", "application/json");

            params.put("ID",id.getText().toString().trim());
            params.put("Nama", nama.getText().toString().trim());
            params.put("Jenis_Kelamin", jenis_kelamin.getText().toString().trim());
            params.put("Tgl_Lahir",tgl_lahir.getText().toString().trim() );
            params.put("ID_Jabatan",id_jabatan.getText().toString().trim());
            params.put("Salary",salary.getText().toString().trim());
            //kembali ke parameters

            Log.e(TAG, "" + params);
            return params;
        }
    };

    AppController.getInstance().addToRequestQueue(stringRequest, tag_json_obj);
}

错误信息

最佳答案

在您的代码中

  StringRequest stringRequest = new StringRequest(Request.Method.POST,
  url,new Response.Listener<String>() {})

更改为

 StringRequest stringRequest = new StringRequest(Request.Method.PUT, url,
   new Response.Listener<String>() {})
