Question

我正在尝试将包含文件的多部分表单数据从一个api发布到另一个。为此，我使用axios和一个FormData库来处理要发送的数据

import { ReadStream } from "fs"
import Axios from "axios"
import * as fs from "fs"
const FormData = require('form-data')

let formData: FormData = new FormData()      
formData.append('name', name)
formData.append('allowPrint', 'false')
const file: ReadStream = fs.createReadStream(name)
formData.append('content', file, name)

return Axios.post(fileAPIUrl + "/file", formData, {
       headers: {
       "Origin": origin,
       "Authorization": "Bearer " + securityToken,
       "Content-Type": "multipart/form-data"
       }, responseType: "json"
})

我应该收到一个json，其中包含我刚刚上传的文件的ID。我知道其他api可以正常工作，因为从前端开始工作，我可以从前端发布包含更多信息的文件，但是如果我从后端使用此网址，则会收到以下错误：

You are likely using an old version; this bug has been fixed in https://github.com/follow-redirects/follow-redirects/issues/50/.
