当前微信接口类已实现以下接口，代码上如果不够简洁的，请自行处理。
1.获取access_token
2.获取用户基本信息
3.生成带参数二维码
4.新增永久素材
5.新增临时素材
6.发送微信模版
7.网页授权获取用户基本信息
8.分享朋友圈
关于需要使用poststr字符串可以在asp.net 页面进行poststr配置
//获取素材列表
var jsonitem = new
{
type = "image",
offset = 0,
count = 999
};
JavaScriptSerializer js = new JavaScriptSerializer();
string poststr = js.Serialize(jsonitem);
