目录

• 在主界面获取到url的信息  html
• 将存储到localStorage中的信息发生请求   vue

<script>
 
  let getRequest = function () {
    var url = location.href
    // 从 URL 中提取查询参数部分
    const queryParamsString = url.split('?')[1];
    // 使用 URLSearchParams 解析查询参数
    const queryParams = new URLSearchParams(queryParamsString);
    // 获取特定参数的值
    const userName = queryParams.get('userName');
    const loginMode = queryParams.get('loginMode');
    localStorage.setItem("userName",userName)
    localStorage.setItem("loginMode",loginMode)
  }
 
  getRequest()
</script>

  created() {
    this.loginInfo.userAcct = localStorage.getItem("userName") || "";
    this.loginInfo.loginMode = localStorage.getItem("loginMode") || "";
    if (this.loginInfo.userAcct !== "" && this.loginInfo.loginMode !== "") {
          // 直接在localstroage获取的信息 调用登录接口
        $login(this.loginInfo)
        .then((res) => {

    // this.getRemInfo();
    this.enterEvent(); // 回车键登录
  },
