const redirectUrl = encodeURIComponent(window.location.href)

    let login_url = `https://open.weixin.qq.com/connect/oauth2/authorize?appid=${config.wxAppId}&redirect_uri=${redirectUrl}&connect_redirect=1&response_type=code&scope=snsapi_userinfo&state=LOGIN_H5#wechat_redirect`;

    window.location.href = login_url

获取到的code换不到基础信息
