vue跳转新页面后,清除url里面的参数,就是上一个页面带过来的参数,只用一次
mounted () {
this.$nextTick(() => {
let url = this.getnewurl()
window.history.replaceState(null, null, url);
})
},
methods: {
//根据参数名去清除,可以多个
getnewurl () {
let url = document.location.href;
let reg = /[^\w](url参数名|url参数名)=?([^&|^#]*)/g;
url = url.replace(reg, "");
reg = /&&/g;
url = url.replace(reg, "");
reg = //g;
url = url.replace(reg, "#");
reg = /\?#/g;
url = url.replace(reg, "#");
// url = url.replaceAll(document.domain,"");
// url = url.replaceAll("http://","");
// url = url.replaceAll("https://","");
reg = /\?#/g;
url = url.replace(reg, "#");
return url;
},
点击 登录按钮
调取后端接口
接口返回跳转链接
,前端新窗口打开链接
并调接口将链接中的参数传给后端
,后端返回成功
即页面直接跳转首页
1.点击 登录按钮 调接口 获取到 要跳转的链接 使用 window.open
新页面打开
2.获取到跳转链接后 在mounted 中判断,该链接中 是否有code参数,有则拿到code值,调第二个接口,接口返回成功后,跳转首页

当用户点击退出登陆后,页面会跳到带有参数的登录页,而不是一开始的登录页,跳转到带有参数的登录页又会直接进入首页。所以 考虑到这个问题,在代码中加了一步 去掉返回链接中的 参数 功能
这样就可以 点击退出登录 跳转登录页 就不会立马又跳回首页啦
