vue-router.esm.js:2065 Uncaught (in promise) NavigationDuplicated: Avoided redundant navigation to current location: "/search/hw".

错误信息 "vue-router.esm.js:2065 Uncaught (in promise) NavigationDuplicated: Avoided redundant navigation to current location: "/search/hw"" 表明在点击同一个跳转路由时，出现了重复导航的错误。这个错误可以通过重写 `push` 和 `replace` 方法来解决。在目录router的index.js中重写这两个方法，可以处理异常并避免重复导航的错误。

代码示例：

let originPush = VueRouter.prototype.push;
let originReplace = VueRouter.prototype.replace;

VueRouter.prototype.push = function(location, resolve, reject) {
  if (resolve && reject) {
    originPush.call(this, location, resolve, reject);
  } else {
    originPush.call(this, location, () => {}, () => {});
  }
}

VueRouter.prototype.replace = function(location, resolve, reject) {
  if (resolve && reject) {
    originReplace.call(this, location, resolve, reject);
  } else {
    originReplace.call(this, location, () => {}, () => {});
  }
}

这样重写之后，再点击同一个跳转路由时就不会再出现重复导航的错误了。
