For any HTTP status other than 200, it seems the 'Unexpected response code 400' is a problem. Does anyone have a way to bypass this 'error'? Code: protected void getLogin() { final String mURL = "https://somesite.com/api/login"; EditText username = (EditText) findViewById(R.id.username); EditText password = (EditText) findViewById(R.id.password); // Post params to be sent to the server HashMap

Android Volley框架的几种post提交请求方式

首先简单描述一下Google的Android开发团队在2013年推出的一个网络通信框架Volley.它的设计目标是进行数据量不大,但通信频繁的网络操作,而对于大数据量的网络操作,比如下载文件等,Volley的表现就不尽如人意。 在app开发中,我们最常见的就是从app客户端向服务端发一个http请求.对于两种基本的web请求方式get和post来说,get请求方式相对比较简单,在此略过不表.本文重点描述一下通过volley进行几种post提交的方式. 1.客户端以普通的post方式进行提交,服务端返回字符串 RequestQueue requestQueue = Volley.newRequestQueue(getApplicationContext()); StringRequest stringRequest = new StringRequest(Request.Method.POST,httpurl, new Response.Listener<String>() { @Override public void onResponse(String response) { Log.d(TAG, "response -> " + response); } }, new Response.ErrorListener() { @Override public void

I am using the Apache Sling JSONObject to model my JSON Object and turn it into a String, so if the Sling JSONObject can be set to output a tidy string (which I do not think it can) that would work too. If i need a 3rd party lib i would prefer one w as few dependencies as possibles (such as Jackson which only requires the std JDK libs). 回答1: You don't need an outside library.
