问题发现
文件上传出现：Required request part ‘file’ is not present 这个错误且后端接口通过postman能够请求成功，但前端怎么也上传不成功，明明配置好了请求头而且数据也放置在了data中如：![vue[文件上传Required request part ‘file‘ is not present]](https://image.shishitao.com:8440/aHR0cHM6Ly9waWFuc2hlbi5jb20vaW1hZ2VzLzcxMC84NWRkNzEzYTc0NjIxYzE2NWJiYjYyYTk0YzU5ZDIwNi5wbmc%3D.png?w=700&webp=1 "vue[文件上传Required request part ‘file‘ is not present]")
![vue[文件上传Required request part ‘file‘ is not present]](https://image.shishitao.com:8440/aHR0cHM6Ly9waWFuc2hlbi5jb20vaW1hZ2VzLzc2My8wYWY1ZWIxN2RkMDMwZmFmMzZiYWYyMmFmZjQzMzMxMy5wbmc%3D.png?w=700&webp=1 "vue[文件上传Required request part ‘file‘ is not present]")
问题解决
通过FormData进行文件数据的封装保存，然后直接放入data中即可![vue[文件上传Required request part ‘file‘ is not present]](https://image.shishitao.com:8440/aHR0cHM6Ly9waWFuc2hlbi5jb20vaW1hZ2VzLzI3Ni9jNzgxNzg0MWU5OThmOWU4YWM5Mjk4ZmJjYzU0YzBlYy5wbmc%3D.png?w=700&webp=1 "vue[文件上传Required request part ‘file‘ is not present]")

然而请求头Content-type格式和请求权限都配置好了，然后body中放置了内容，然后报错

使用axios配置请求信息![vue[文件上传Required request part ‘file‘ is not present]](https://image.shishitao.com:8440/aHR0cHM6Ly9waWFuc2hlbi5jb20vaW1hZ2VzLzc3OS9iMjI2ZGUwMmUyMmVhMTRmMjA4YzAwYTU4ODZmMjhhMy5wbmc%3D.png?w=700&webp=1 "vue[文件上传Required request part ‘file‘ is not present]")
