android开发学习 ------- volley网络请求的实例

在  http://www.sojson.com/httpRequest/  上对http进行访问，将此访问在android中的应用

****************************************************************************************

对于上边的请求，在Android中这样写就可以成功：(请求参数是json，返回值也是json)

public void test(String customerId, String pinNumber){
        String url = "https:xxxxxx";

       Map<String, String> params = new HashMap<String, String>();
       params.put("email", customerId);
       params.put("password",pinNumber);
       JSONObject json = new JSONObject(params);
      //这里不用 JsonObjectRequest ,这个太多的坑了
       StringRequest request = new StringRequest(Method.POST,url,json,new Response.Listener<String>() {
           @Override
           public void onResponse(String response) {
               try {
                   JSONObject resp = new JSONObject(response);
                   String success = resp.getString("success");
                   String msg = resp.getString("msg");
                   if(success.equals("true")){
                       //返回true，,意思是后台db中找到此用户，然后跳转到MainPagerActivity界面
                       Log.e("log","success return true , msg - :"+msg);                                         

                   }else{
                       //success = false,意思是后台db没有找到此用户

                       }
                   }

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

           }
       }, new Response.ErrorListener() {
           @Override
           public void onErrorResponse(VolleyError volleyError) {
               Log.e("log","error");
           }
       }
       ){
           public Map<String, String> getHeaders() {
               HashMap<String, String> headers = new HashMap<String, String>();
               headers.put("Authorization", "xxxxxxxxxx");
               return headers;
           }

       };

       request.setRetryPolicy(new DefaultRetryPolicy(60 * 1000, 1, 1.0f));
       request.setTag(this);
       mRequestQueue.add(request);

   }
