文章讲述了在项目测试中，使用requests.get函数调用接口时遇到超时错误，原因是默认的User-Agent被识别为爬虫。解决方法是添加通用的User-Agent请求头，模拟浏览器行为，从而成功避免了服务器拒绝。

摘要生成于 C知道 ，由 DeepSeek-R1 满血版支持， 前往体验 >

背景：

项目测试中需要模拟三方调用接口，

使用

res = requests.get(url=url, params) 

一直报错超时

  File "D:\pythonProject2\venv\lib\site-packages\requests\adapters.py", line 501, in send
    raise ConnectionError(err, request=request)
requests.exceptions.ConnectionError: ('Connection aborted.', TimeoutError(10060, '由于连接方在一段时间后没有正确答复或连接的主机没有反应，连接尝试失败。', None, 10060, None))

原因分析：

在requests请求中，添加请求头，是常见的处理反扒的一种措施。

如果不传参数，request会使用默认请求头，

User-Agent：python-request， 这种会被识别成爬虫程序，服务器拒绝掉超时

处理方案：

加个通用的请求头，指定请求设备信息之类

headers={'User-Agent': 'Mozilla/5.0 (Windows NT 6.0; WOW64; rv:24.0) Gecko/20100101 Firefox/24.0'}

然后再测试，则成功

网上说的什么只需要在请求头中加verify=False，完美解决的什么话，根本试了没用好吧，还有安装几个request辅助模块的方法，也试过了，没有用。。。首先这个error是时有时无的，所以我就想到了用多次循环来进行requests请求，然后做个异常处理不就行了吗，下面是具体操作： 这个是访问github的API的实例操作： import requests requests.packages.urllib3.disable_warnings() #执行API调用并储存响应 url='https://api.github.com/search/repositories?q=language:

这个原因是因为把fiddler开着的，这个时候去请求就会报错，解决方法是降低requests的版本即可。 pip3 uninstall requests pip3 install "requests==2.20" 可以使用 pip list查看各个模块的版本，我之前的版本是2.26，降到2.20后就可以了。 ...

安装visdom 切换到conda对应的环境下，使用conda install visdom，报错无法安装，查询后发现使用pip安装可以成功，不知为何，命令如下： pip install visdom 运行visdom 如果要在python代码中使用visdom，必须先到安装visdom的conda环境下启动visdom服务： python -m visdom.server 服务启动后会给出如下提示： 39: DeprecationWarning: zmq.eventloop.iolo.
