以下命令有效，但我无法使用python-requests（2.18.4）重现它：
curl -X POST -H "Authorization: Bearer ..." \
-H "Content-Type: multipart/form-data" \
-F 'metadata={...}
-F 'data=@data.bz2;type=application/octet-stream'
https://www....com
使用下面的send_devices，我收到＆＃34;不支持的媒体类型＆＃34;＆＃34;
def send_devices(basic_auth):
endpoint_api = ' https://www....com'
with open('data.bz2','rb') as payload:
response = requests.post(endpoint_api, data={'metadata': ...,
'data': payload},
headers={'Authorization': 'Bearer {0}'.format(basic_auth})
经过一些评论后，我也尝试了，现在的错误是＆＃34;无效的元数据Json字符串＆＃34;：
def send_devices(basic_auth):
endpoint_api = ' https://www....com'
files = {'file': ('data.bz2', open('data.bz2', 'rb'), 'application/octet-stream')}
response = requests.post(endpoint_api, data={"metadata": {"extensions":{"urnType":"IDFA"}}},
files=files, headers={'Authorization': 'Bearer {0}'.format(basic_auth)})

确保有效负载格式正确。您的有效负载中的第二个对象中似乎缺少“{”。
HTTP 415不支持的媒体类型客户端错误响应代码表示服务器拒绝接受请求，因为有效内容格式的格式不受支持。

你应该把它作为文件（而不是数据）。
r = requests.post(url, files={'file': open('data.bz2', 'rb')})
工作正常。

在第二个示例中，需要在相同的文件dict上添加额外的帖子数据。即使不是一个字典：
'data': ('data.bz2', open('data.bz2', 'rb'), 'application/octet-stream'),
解决方案：
'metadata': ('metadata.csv', json.dumps({"extensions": ...}))}
