1、获取code 根据code 获取openId
getUrlKey:function(name){//获取url 参数 return decodeURIComponent((new
RegExp('[?|&]'+name+'='+'([^&;]+?)(&|#|;|$)').exec(location.href)||[,""])[1].replace(/\+/g,'%20'))||null;
} function getCodeApi(state){//获取code let
urlNow=encodeURIComponent(window.location.href); let scope='snsapi_base';
//snsapi_userinfo //静默授权 用户无感知 let appid='wx4cc5d5c123123123'; let
url=`https://open.weixin.qq.com/connect/oauth2/authorize?appid=${appid}&redirect_uri=${urlNow}&response_type=code&scope=${scope}&state=${state}#wechat_redirect`;
window.location.replace(url); } created(){ let code=getUrlKey("code");
if(code){ //调用接口获取openId
参考文档https://mp.weixin.qq.com/wiki?t=resource/res_main&id=mp1421140842
getOpenIdApi(code).then(res=>{ let openId=res.openId;
window.location.replace("/#/login"); }).catch(res=>{
window.location.replace("/#/login"); }) }else{ getCodeApi("123"); } }
