python - 在使用 Python 的 POST 多部分请求期间连接中止

Question

我正在尝试使用 Python 将 .csv 文件上传到服务器。

这是我制作的代码：

import requests
import json
import globals
from pathlib import Path
import mimetypes
from requests_toolbelt.multipart.encoder import MultipartEncoder

def upload():
    uploadfile = open(globals.uploadfilepath,"r")
    filename = globals.uploadfilepath.split("\\")[-1]
    length = Path(globals.uploadfilepath).stat().st_size
    meta = '\"FileCount\":1,\"FileIndex\":1,\"FileSize\":' + str(length) + ',\"FileVersion\":\"\"'
    mime = MultipartEncoder(
    fields={'FileMetaData': meta,
            'file': (filename, open(globals.uploadfilepath, 'rb'), 'application/csv')}
    )
    url = globals.protocole + "://" + globals.ip + "/UploadFile"
    head = {'authentificated=true;username=admin','Content-Type': mime.content_type}
    
    resp = globals.envoi.post(url,data=mime, headers=head, verify=False)

如您所见，我使用 requests 和 requests-toolbelt 包。

当我使用 Firefox 上传文件时，我已经能够使用 WireShark 查看包，而当我使用 python 上传文件时，一切看起来都相似，只是在使用 Python 时我从未得到任何对我的请求的答复。

这是我收到的错误：

我不明白问题出在哪里。

任何帮助都应该不胜感激。
