微信接口小例

微信基础类：用于连接微信的API，获取或发送数据。

public class WeixinSms
    {
        private WeiXinConfig wxConfig;

        public WeixinSms(WeiXinConfig config)
        {
            this.wxConfig = config;
        }

        public string Send(JMSendSms jmsms)
        {
            string url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token=" + WeiXinBase.GetAccessToken(this.wxConfig);
            return WeiXinBase.HttpPost(url, JsonHelper.ToJson<JMSendSmsAll>(jmsms));
        }

        public string SendAll(JMSendSmsAll jmall)
        {
            string url = "https://api.weixin.qq.com/cgi-bin/message/mass/sendall?access_token=" + WeiXinBase.GetAccessToken(this.wxConfig);
