自己手動解析:

 {"body" :   {"mobile":"13714664734","email":"","icon":"","open_id":"f5994ced6530405ebc07f8fecd1beb12","country_code":"86","user_name":"13714664734","is_update_name":"0"},

"code":"0","msg":"成功"}

{}:是對象--->sonObject = new JSONObject(response);jsonBody = jsonObject.optJSONObject("body");String mobile= jsonBody .optString("mobile");{   "body":    {      "PRoducts": [      {         "describe": "無流量限制",         "type": 1,    //產品類型(0:虛擬 1:實際)         "      }],      "coupons": [      {         "name": "折扣券",     //優惠券名稱         "describe": "",    //優惠券描述      }],      "amount": 12.11,  //訂單總金額      "order_num": "12000100", //訂單流水號       },   "code": "0",   "msg": "成功"}

[]:是集合 :

JSONArray jsonArrayProList = jsonBody.optJSONArray("products");

jsonArrayProList  是集合,定義循環,解析多個products.

JSONObject jsonObjectOne = jsonArrayProList.optJSONObject(i);String     describe      = jsonObjectOne.optString("describe");
