vue报错Path "/main" was passed with params but they will be ignored. Use a named route alongside params instead.

这个错误提示是因为你在路由跳转时传递了参数，但是没有使用命名路由，导致参数被忽略了。解决方法是在定义路由时使用命名路由，并在跳转时使用该命名路由，并将参数作为参数对象的属性传递。例如：

定义路由时：

const routes = [
  {
    path: '/main/:id',
    name: 'main',
    component: Main
  }
]

跳转时：

this.$router.push({ name: 'main', params: { id: 123 }})

这样就可以正确传递参数并跳转了。

Extraneous children found when component already has explicitly named default slot. These children will be ignored.vue(39)

The warning message "Extraneous children found when component already has explicitly named default slot. These children will be ignored." is usually encountered in Vue.js when you try to pass children to a component that already has an explicitly named default slot.

In Vue.js, a component can have multiple slots to render different content. By default, any content that is not explicitly assigned to a named slot is rendered in the default slot. However, if a component already has a named default slot, any additional children passed to the component will be ignored and produce this warning.

To resolve this issue, you have a few options:

1. If you intended to pass the children to the default slot, make sure that the component does not have any explicitly named default slot. Remove any `slot` attribute with a specific name from the component's template.

2. If you want to assign the children to a named slot, make sure to update the component's usage accordingly. Pass the children as a separate prop or wrap them in a container element and assign that container to the named slot.

Here's an example to illustrate the second option:

<template>
  <div>
    <slot name="header"></slot>
    <slot></slot>
  </div>
</template>

<script>
export default {
  name: 'MyComponent',
}
</script>

In your parent component:

<template>
  <my-component>
    <template v-slot:header>
      <!-- header content goes here -->
    </template>

    <!-- other content goes here -->
  </my-component>
</template>

<script>
import MyComponent from '@/components/MyComponent.vue'

export default {
  components: {
    MyComponent,
  },
}
</script>

By assigning the children to the named slot, you can avoid the warning message and ensure that the content is rendered correctly within the component.

vue报错TypeError: Router.use() requires a middleware function but got a Object

这个错误提示表明在Vue应用程序的路由中使用了不正确的中间件。路由中间件是用于处理传入请求的函数，如果你想在路由中使用中间件函数，你需要确保传入的中间件是一个函数。如果你使用的是第三方中间件，请确保正确导入该中间件并使用正确的参数。

如果你自己编写路由中间件，可以确保中间件函数按照以下格式编写：

function myMiddleware(req, res, next) {
  // 处理请求
  next();
}

其中，`req`表示请求对象，`res`表示响应对象，`next`表示将控制传递给下一个中间件的函数。如果你使用的中间件不符合这个格式，你需要将其更改或更换为符合要求的中间件。

如果你确定中间件函数正确，但仍然遇到此错误，请检查路由定义中是否有错误。可能存在无效的路由定义或者路由定义中未使用正确的中间件。
