在android studio中使用JSON正文的Google截击POST请求？

Question

这是我用来发出POST请求的一段代码。

RequestQueue requestQueue = Volley.newRequestQueue(MainActivity.this);

            String url = "myUrl.....";
            StringRequest stringRequest = new StringRequest(Request.Method.POST, url, response -> {
                Toast.makeText(MainActivity.this, "Response: "+response, Toast.LENGTH_SHORT).show();
                try {
                    JSONObject mainObject = new JSONObject(response);
                    error = mainObject.getBoolean("error");
                    //Toast.makeText(getApplicationContext(), error, Toast.LENGTH_SHORT).show();
                } catch (JSONException e) {
                    e.printStackTrace();
                }

                if(!error){
                    SharedPreferences.Editor editor = sharedPreferences.edit();
                    editor.putString(userNameShared, email);
                    editor.putString(passwordShared, password);
                    editor.commit();
                    startActivity(new Intent(MainActivity.this, MainActivityDashboard.class));
                }
                else{
                    editTextEmail.setError("Invalid e-mail");
                    editTextPassword.setError("Invalid password");
                    return;
                }

            }, error -> Toast.makeText(MainActivity.this, "Error: "+error.getMessage(), Toast.LENGTH_SHORT).show()){
                @Override
                protected Map<String, String> getParams() throws AuthFailureError
                {
                    Map<String,String> params = new HashMap<String, String>();
                    params.put("email", email);
                    params.put("password", password);
                    params.put("rememberPassword", false);
                    params.put("ip_address", ipAddress);
                    params.put("isCaptchaEnabled", false);
                    return params;
                }

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

            requestQueue.add(stringRequest);
        });

在以前的项目中，一切都很好地工作，但现在的问题是，我想在帖子正文中包括布尔值和字符串值。

正文如下：{"email"："[e-mail]"，"密码"："Somepassword"，"rememberPassword"： false，"ip_address"："152.57.31.41"，"isCaptchaEn的"： false}

我不熟悉API调用和JSON。我试着在谷歌上搜索答案，但每个人都在使用地图

答案相当简单。我们可以使用JsonObjectRequest并将参数传递给它。这是我的工作代码，以防有人面临同样的天真问题。

String postUrl = "yourURL.....";
            RequestQueue requestQueue = Volley.newRequestQueue(this);

            JSONObject postData = new JSONObject();
            try {
                postData.put("email", editTextEmail.getText().toString());
                postData.put("password", editTextPassword.getText().toString());
                postData.put("rememberPassword", false);
                postData.put("ip_address", "1.41");
                postData.put("isCaptchaEnabled", false);

            } catch (JSONException e) {
                e.printStackTrace();
            }

            JsonObjectRequest jsonObjectRequest = new JsonObjectRequest(Request.Method.POST, postUrl, postData, new Response.Listener<JSONObject>() {
                @Override
                public void onResponse(JSONObject response) {
                    Toast.makeText(getApplicationContext(), "Response: "+response, Toast.LENGTH_LONG).show();
                }
            }, new Response.ErrorListener() {
                @Override
                public void onErrorResponse(VolleyError error) {
                    error.printStackTrace();
                }
            });

            requestQueue.add(jsonObjectRequest);
