如何使用Python使用多/表单数据进行POST请求?

Question

我对API的东西很陌生。

我必须用以下"格式"向API发出POST请求

content-type: multipart/form-data
Content-Disposition: form-data; name=""; filename=""
Content-Type: application/vnd.openxmlformats-officedocument.spreadsheetml.sheet
Form data:
file = file.xlsx

如何使用Python执行API请求?

使用请求库，我可以执行它吗:

requests.post(
'api_url', 
headers = {'Content-Type':'application/vnd.openxmlformats-officedocument.spreadsheetml.sheet'},
data = {"filename.xlsx": open(filepath, "rb")}
)

感谢

我更喜欢池管理器，因为它可以很容易地管理超时、重试等:

import urllib3
from urllib3.util import Retry, Timeout
http_client = urllib3.PoolManager(retries=Retry(connect=5, read=2, redirect=5),
timeout=Timeout(connect=5.0, read=10.0),
num_pools=2)
data = {'asd': 'asd'}
request = http_client.request('POST', "http://localhost:8081",  fields=data, encode_multipart=True)

这将给你:

>nc -l 127.0.0.1 8081
POST / HTTP/1.1
Host: localhost:8081
Accept-Encoding: identity
Content-Length: 125
Content-Type: multipart/form-data; boundary=6ce0c07687204c761cc1e5a6d6f6046e
User-Agent: python-urllib3/1.26.4
--6ce0c07687204c761cc1e5a6d6f6046e
Content-Disposition: form-data; name="asd"
