Question

我收到错误消息“Bad Gateway

代理服务器收到无效来自上游服务器的响应“使用以下代码：

import requests

url = "https://apis.company.com/v3/media"
attachments = 'media': ('x.mp3', open('x.mp3', 'r'))}
headers = {'content-type': "multipart/form-data",'cache-control': "no-cache" 
          'Authorization':"Bearer zzz" }
response = requests.post(url, files=attachments, headers = headers)
print response.text

我正在请求Quickstart文档中的示例，其中显示“您还可以将元组列表传递给数据参数”：http://docs.python-requests.org/en/master/user/quickstart/#post-a-multipart-encoded-file

导致此错误的原因是什么？如何解决？

主要问题是我在标题中设置了内容类型。此代码有效：

    import requests

    url = 'https://apis.company.com/v3/media'
    token = 'token-goes-here'

    headers = { 'Authorization' : 'Bearer ' + token }

    filename = 'x.mp3'

    with open(filename, 'rb') as media_file:

    attachments = {
'media': (filename, media_file, 'application/octet-stream')
 }

    response = requests.post(url, files = attachments, headers = headers)

    print response.text

使用带有多部分编码文件的Python请求模块发出“错误网关”错误
