尝试上传文件时使用HTTP 500

Question

这是我的Box上传POST，用于将文件上传到特定文件夹：

POST /api/2.0/files/content HTTP/1.1
Authorization: Bearer ACCESS_TOKEN
Accept: application/json
User-Agent: SOASoftware/7-HttpCore/4
Transfer-Encoding: chunked
Content-Type: multipart/form-data
Host: upload.box.com
Connection: Keep-Alive

attributes='{"name":"lead.txt", "parent":{"id":"2890481033"}}'&file=C:\SOA\Software\sm70\instances\nd\leads.txt
-----------------------------9051914041544843365972754266
<file-data>
-----------------------------9051914041544843365972754266

但是我得到了这个回复，但这并不能帮助我理解问题所在：

HTTP/1.1 500
Age: 0
Date: Fri, 02 Jan 2015 09:06:09 GMT
Connection: close

EMPTY MESSAGE

谁能告诉我在导致HTTP 500的请求中我做错了什么？

Answer 1

看来您的分段请求格式不正确。 最简单的方法是使用SDK或查找可以为您构建多部分请求的库。

如果您确实要手动构建请求，那么以下是一个上传请求的示例：

POST https://upload.box.com/api/2.0/files/content HTTP/1.1
Host: upload.box.com
Authorization: Bearer ACCESS_TOKEN
Content-Length: 346
Content-Type: multipart/form-data; boundary=------------------------393329c2f2238ab4

--------------------------393329c2f2238ab4
Content-Disposition: form-data; name="attributes"

{"name":"my-file.txt", "parent":{"id":"0"}}
--------------------------393329c2f2238ab4
Content-Disposition: form-data; name="file"; filename="my-file.txt"
Content-Type: application/octet-stream

<file-data>
