Python SSL connection "EOF occurred in violation of protocol"
提问by user962563
I'm using Django Celery task to connect to Facebook Graph API with requests lib using Gevent. Issue I'm constantly running at is that every now and then I get EOF occurred in violation of protocol exception. I've searched around and various sources offer different fixes but none seems to work.
我正在使用 Django Celery 任务通过 Gevent 请求库连接到 Facebook Graph API。我经常遇到的问题是，我时不时地发生违反协议异常的 EOF。我四处搜索，各种来源提供了不同的修复方法，但似乎都不起作用。
I've tried monkey patching the ssl module(gevent.monkey.patch_all()) and some others too but no luck.
我试过猴子修补 ssl 模块(gevent.monkey.patch_all()) 和其他一些，但没有运气。
I'm not even sure if this is openssl issue as some sources might suggest as I haven't encountered it before applying Gevent optimisation
我什至不确定这是否是 openssl 问题，因为某些来源可能会建议，因为我在应用 Gevent 优化之前没有遇到过
Connection error: [Errno 8] _ssl.c:504: EOF occurred in violation of protocol
Traceback (most recent call last):

raise SSLError(e)
SSLError: [Errno 8] _ssl.c:504: EOF occurred in violation of protocol
I'm using latest 1.0rc Gevent version.
我正在使用最新的 1.0rc Gevent 版本。
Another issue that keeps poping up time to time although URL is correct is: Retrying (5 attempts remain) after connection broken by 'error(2, 'No such file or directory')': /ID/events?limit=5000&fields=description,name,location,start_time,end_time&access_token=TOKEN
尽管 URL 正确，但仍不时出现的另一个问题是：在连接因“错误（2，“没有这样的文件或目录”）而中断后重试（剩余 5 次尝试）：/ ID/events?limit=5000&fields=description ,name,location,start_time,end_time&access_token= TOKEN

I installed the latest Python 2.7 (2.7.11) and the problem went away. I believe the problem might even be solved back in 2.7.6 (I was using 2.7.5 on Mac OSX).
我安装了最新的 Python 2.7 (2.7.11)，问题就解决了。我相信这个问题甚至可以在 2.7.6 中解决（我在 Mac OSX 上使用 2.7.5）。

I was having the same error during fetching tweets for my machine learning . Doing the pip install of the following helped me. This works:
我在为我的机器学习获取推文时遇到了同样的错误。执行以下 pip 安装对我有帮助。这有效：
pip install ndg-httpsclient
pip install pyopenssl
pip install pyasn1
It removed my SSLError: EOF occurred in violation of protocol (_ssl.c:590) error.
它删除了我的 SSLError: EOF 发生违反协议 (_ssl.c:590) 错误。
Hope it helps.
