python - 连接中止。，Django 中的错误(104， 'Connection reset by peer')

Question

我在 Django 中创建了一个 API，并在其中调用接受 XML 数据的第三方 API。对于 30 行 XML，它工作正常，对于更多行，会抛出错误“连接已中止。”，错误(104，“连接由对等方重置”)”。第三方还提供了一个 UI，因此我可以测试他们接受的最多 5000 行并返回正确的结果。这两个 API 均未关闭连接。可能是什么问题？

预期结果

对于请求中的更多数据，post 请求应该可以正常工作，因为它对于较少的数据也可以正常工作。

实际结果

复制步骤

import requests

recievers = ''
url = 'https://example.com/sms/'
for x in xrange(0, len(users)):
    y = x + 1
    body_content = body
    phone = mobile_no
    recievers = recievers + "<SMS>.......</SMS>"

xml = "<?xml version=\"1.0\" encoding=\"ISO-8859-1\"?>\n<!DOCTYPE MESSAGE SYSTEM \"http://127.0.0.1:80/sms/ttr/sms.ptp\">\n<MESSAGE VER=\"1.2\">\n<USER USERNAME=\""+username+"\" PASSWORD=\""+password+"\" />"+recievers+"\n</MESSAGE>"

querystring = {"data": xml,"action":"send"}
headers = {'content-type': "application/xml"}
response = requests.request("POST", url, headers=headers, params=querystring)

Answer 1

尝试将“params=querystring”替换为“data=querystring”

 response = requests.request("POST", url, headers=headers, data=querystring)

params 似乎用于 GET 请求，并且可能会导致您的请求 URL 在 30 行 XML 后变得太长。
