error in created hook: "referenceerror: axios is not defined"

这个错误提示是在创建钩子函数时出现了问题，具体是因为axios未定义。可能是因为没有正确引入axios库或者没有在组件中声明axios。需要检查代码中是否正确引入了axios，并且在组件中声明了axios。

Error in created hook: "ReferenceError: axios is not defined"

This error indicates that the axios library is not imported or defined in the file where the created hook is used. To fix this error, you need to import axios in the file where you are using it.

Here is an example of how to import axios in a Vue component:

<template>
  <div>
    <!-- Your component code here -->
  </div>
</template>

<script>
import axios from 'axios';

export default {
  name: 'MyComponent',
  created() {
    axios.get('/api/data')
      .then(response => {
        console.log(response.data);
      })
      .catch(error => {
        console.log(error);
      });
  }
}
</script>

<style>
/* Your component styles here */
</style>

In this example, we import axios using `import axios from 'axios';` at the beginning of the script section. We then use axios in the created hook to make an HTTP GET request to an API endpoint.

Error in created hook: "ReferenceError: request is not defined"

这个错误提示表明在created钩子函数中使用了一个未定义的变量request。可能的原因是没有正确导入或声明request变量。解决方法是检查代码中是否正确导入了需要使用的模块或变量，并确保变量名没有拼写错误。
