浙里办微信小程序单点登录流程

1.获取浙里办跳转地址中ticket或者微信小程序中的ticketId

    let ticket = getQueryString("ticket", window.location.href);
    let sp = getQueryString("sp", window.location.href);
    let ticketId = getQueryString("ticketId", window.location.href);
    if (ticket) {
      ticket = ticket.replace("#/", "");
    }

    console.log("拿到用户信息后跳转到测试地址前", sp, ticket, ticketId);
    if (sp) {
      sp = sp.replace("#/", "");
      console.log("拿到用户信息后跳转到测试地址", sp, ticket);
      if (sp.indexOf("?") != -1) {
        window.location.href = sp + "&ticket=" + ticket;
      } else {
        window.location.href = sp + "?ticket=" + ticket;
      }
      console.log("ticket", ticket);

      return false;
    }

2.判断一下当前环境并且去缓存中拿到用户信息

    const sUserAgent = window.navigator.userAgent.toLowerCase();
    const bIsAlipayMini =
      sUserAgent.indexOf("miniprogram") > -1 &&
      sUserAgent.indexOf("alipay") > -1;

    const isWx = sUserAgent.indexOf("micromessenger") > -1;

    let userInfo = window.sessionStorage.getItem("userInfo");

3.判断一下是否存在用户信息，如果存在按照当前环境去进行跳转

    if (!userInfo) {
      console.log("进入userInfo-----ticketId", isWx, ticketId);
      if (isWx) {
        // 微信小程序中的单点登录组件，获取 ticketId
        this.wxApply();
        console.log("微信小程序--走链接后", window.location.href);
      } else if (bIsAlipayMini && !ticket && !ticketId) {
        //支付宝app
        this.watchApply();
      } else if (!ticket && !ticketId) {
        //浙里办app
        this.watchApp();
      }
      if (ticket) {
        console.log("ticket--存在", ticket);
        this.getUserInfo(ticket);
      }
   }
