上传oss图片文件时需要的jwt令牌获取

src\utils\cookies.js

import Cookies from 'js-cookie';


// 获取令牌
export const getToken = () => sessionStorage.getItem('jwtToken');

ps:如果出现模块找不到,不存在的时候,直接

npm install 模块

例如:

Module not found: Error: Can't resolve 'js-cookie' in 'D:\bishe\project\sems-front\src\utils'

解决方法:

这个错误表明你的项目无法找到js-cookie模块,这意味着你可能还没有安装它或者路径配置有问题。js-cookie是一个用于操作浏览器Cookies的小型JavaScript库。

解决方案

安装 js-cookie

确保你已经安装了js-cookie。你可以通过运行以下命令来安装它:

npm install js-cookie --save

或者如果你使用的是Yarn:

yarn add js-cookie

测试:

ps:OSS折磨死我了,踩了无数的坑,全靠各种搜索资料,卡了我2天,呜呜呜,麻了,有什么不知道的真可以问我,呜呜呜,你们踩的坑我应该都踩过,麻了

未完。。。
