ValueError：检查主机名需要使用Fiddler 4的服务器主机名 [英] ValueError: check_hostname requires server_hostname using Fiddler 4

问题描述

最近发布的question有一些有用的答案，但与我的不同。我在一台ArcGIS Pro笔记本上运行urllib3 1.26.4和Python3.7。我还打开了Fiddler 4，因为我想在排除脚本故障时跟踪网络流量。当我打开Fiddler时，我只得到以下错误。如果我关闭Fiddler，我会得到<Response [200]>。不能在Fiddler打开的情况下使用requests模块吗？我是小提琴新手。

截断脚本：

import requests

#url
idph_data = 'https://idph.illinois.gov/DPHPublicInformation/api/covidVaccine/getVaccineAdministrationCurrent'
#headers
headers = {'user-agent': 'Mozilla/5.0'}

response = requests.get(idph_data, headers=headers, verify=True)

错误：

推荐答案

我已更新到最新版本requestsv2.7.0，不再收到该错误。如果这是与我使用的2.25.1版相关的版本特定问题，我不确定。我还没有看到任何这方面的证据。

在与我的Python可执行文件相同的目录中的Windows命令提示符中：

python -m pip install requests==2.7.0

现在，如果我运行带有Fiddler捕获的原始脚本，我得到的HTTP状态为200，并且我的脚本不再向我显示该错误。
