 　　　　Note: The underlined part is openId domain name and a callback to be acquired, and location.href = url when the page is first rendered automatically get openId, of course, these preparations or

 1 //截取URL字段
 2     GetQueryString: function(name) {
 3       var reg = new RegExp("(^|&)" + name + "=([^&]*)(&|$)", "i");
 4       var r = window.location.search.substr(1).match(reg);
 5       if (r != null) {
 6         return unescape(r[2]);
 7       }
 8       return null;
 9     },
10     getToken: function() {
11       //判断是否有openid
12       if (this.$cookieStore.getCookie("openid") == null) {
13         var url =
14           "https://open.weixin.qq.com/connect/oauth2/authorize?appid=wx1234567890&redirect_uri=" +
15           encodeURIComponent(
16             "https://www.baidu.com/"
17           ) +
18           "&response_type=code&scope=snsapi_base&state=STATE#wechat_redirect&connect_redirect=1#wechat_redirect";
19         location.href = url;
20         var code = this.GetQueryString("code");
21         // console.log(code);
22         axios({
23           url: "接口名" + code
24         }).then(res => {
25           // console.log(res);
26           if (res.data.code == 0) {
27             this.$cookieStore.setCookie("openid", res.data.result);
28           }
29         });
30       } else {
31         this.openid = this.$cookieStore.getCookie("openid");
32       }
33     },
