Question

我在以下远程服务器设置上使用Python 3.6.5：

服务器：Windows 10

Python：3.6.5

请求：2.18.4

Pentaho：8.0

当我对服务器命令提示符中的URL运行request.get时，它会按预期获得JSON：

>>> import requests
>>> response = requests.get(url, headers=headers)
>>> json = response.json()
>>> print(json)
{'d': {'results': [{'_ ...

然而，当我在CPython中为Pentaho 8.0运行相同的脚本时，我得到了

RecursionError：超出最大递归深度

脚本：

import requests
import json


# By Filename
url = "https://myco.sharepoint.com/teams/dg/l/_api/web/lists/GetByTitle('eRetail%20Data%20Sources')/items?..."

authtoken = "Bearer eyJ..."

headers = {
    "Content-Type": "application/json;odata=verbose",
    "Accept": "application/json;odata=verbose",
    "Authorization": authtoken
}

response = requests.get(url, headers=headers)

json = response.json()
print('===========================')
print(json)

Answer 1

如果安装了gevent，则需要对python socket进行猴子补丁合作（请参阅documentation或this github issue）。

因此gevent.monkey.patch_all()丢失或没有足够早地被调用。

# at the beginning of the script
import gevent.monkey
gevent.monkey.patch_all()

# all the other stuff below, like for example
import requests

Answer 2

请勿猴子修补ssl：

from gevent import monkey
monkey.patch_all(ssl=False)

Answer 3

from gevent import monkey as curious_george
# curious_george.patch_all(thread=False, select=False)
def stub(*args, **kwargs):  # pylint: disable=unused-argument
    pass

Answer 4

<强>更新

我发现我的问题是因为我在我的应用程序的另一个地方引入了locust，它使用了gevent == 1.2.2。在我注释掉gevent import语句之后，这个递归问题就消失了。如果您在应用程序中的某个位置引入了gevent，那么值得一试。

我最近遇到了同样的错误，并没有找到任何解决方法。在我的情况下我不得不使用http而不是https，尽管它确实危险。
