使用Python请求的重定向错误过多 [英] Too many redirects error using Python requests
问题描述
HTTP请求在我的本地主机上运行良好，但是使用服务器上的python请求库运行相同的HTTP请求会返回"Too Many Redirects"错误
HTTP requests are working fine on my localhost, but running the same HTTP requests using the python requests library on my server returns a "Too Many Redirects" error
当我输入
localhost/terminal/jfk
在浏览器中，我得到了预期的json字典.
in a browser, I get a json dictionary as expected.
但是，当我使用服务器上的python请求库在python中运行以下命令时
However, when I run the following in python using the python requests library on my server
requests.get('http://splitmyri.de/terminal/jfk')
我从请求模块收到重定向过多"错误.
I receive a "Too Many Redirects" error from the requests module.
关于导致错误的原因有何想法?还是建议缩小潜在原因?
Any thoughts as to what's causing the error? Or recommendations for narrowing potential causes?
推荐答案
阿莎，
在您回答这确实是您的网站之后，我检查了为什么我得到了一个空的GoDaddy.com页面.问题是您的splitmyri.de的DNS条目返回了两个不同的A记录...
After you responded that this really is your site, I checked out why I was getting an empty GoDaddy.com page. The problem is that your DNS entry for splitmyri.de is returning two different A records...
使用107.10.141.119 分析结果:
我的/etc/hosts 文件中的硬编码 107.10.141.119 splitmyri.de 使我可以查询107.10.141.119，该查询在中返回这是我的网站"> index.html (然后我检查了 http://splitmyri.de/terminal/并得到了一个空的json哈希，具有mime类型= [application/json]).检查此地址的反向条目将返回一个Amazon AWS主机(我期望用于真实网页的那种条目).现在您上面的代码可以按预期工作...
Analyzing results, using 107.10.141.119:
Hard coding 107.10.141.119 splitmyri.de in my /etc/hosts file allowed me to make queries to 107.10.141.119, which returns "this is my site" in index.html (then I checked http://splitmyri.de/terminal/ and got an empty json hash, with a mime type=[application/json]). Checking the reverse entry for this address returns an Amazon AWS host (the kind of entry I expect for a real web page). Now your code above works as expected...

使用68.178.232.100分析结果:
对68.178.232.100的查询执行相同的钻取操作将获得一个空的GoDaddy.com页面.对这个地址进行反向映射会发现一个驻留域的典型条目.如您在尝试中看到的那样，在此处发送请求会返回 TooManyRedirects ...
