完全禁用 grequests 日志记录

Question

如何抑制从 grequests 收到的以下调试错误消息？

Traceback (most recent call last):
  File "/usr/local/lib/python2.7/dist-packages/gevent/greenlet.py", line 327, in run
    result = self._run(*self.args, **self.kwargs)
  File "/usr/local/lib/python2.7/dist-packages/grequests.py", line 71, in send
    self.url, **merged_kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 456, in request
    resp = self.send(prep, **send_kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/sessions.py", line 559, in send
    r = adapter.send(request, **kwargs)
  File "/usr/local/lib/python2.7/dist-packages/requests/adapters.py", line 384, in send
    raise Timeout(e, request=request)
Timeout: HTTPSConnectionPool(host='itunes.apple.com', port=443): Read timed out.
<Greenlet at 0x7ff0c8165910: <bound method AsyncRequest.send of <grequests.AsyncRequest object at 0x7ff0c880b8d0>>(stream=False)> failed with Timeout

这是我到目前为止尝试过的方法：

# disable requests/grequests logging
logging.getLogger("requests").setLevel(logging.CRITICAL)
logging.getLogger("grequests").setLevel(logging.CRITICAL)
logging.getLogger("urllib3").setLevel(logging.CRITICAL)
logging.getLogger("gevent").setLevel(logging.CRITICAL)

这里出现错误：

rs = (grequests.get(url, headers=headers, cookies=cookies, proxies=proxies, timeout=timeout) for url in urls)
res_items = grequests.map(rs) # <-- this command produces all the errors

我收到了数以千计的此类消息，我不想看到这些消息。我还在很多其他地方使用 log.debug，所以不想在程序范围内更改调试级别。我如何只抑制 grequests 调试消息？

Answer 1

为此你需要做三件事：

(1) 确保您安装了最新版本的 grequests：

sudo pip install git+https://github.com/kennethreitz/grequests.git

(2) 拥有 grequests.map 函数的处理程序：

def exception_handler(request, exception):
    pass # suppress errors on grequests.map

res_items = grequests.map(rs, exception_handler=exception_handler)

(3) 抑制 urllib3 警告：

import urllib3
urllib3.disable_warnings()
logging.captureWarnings(True)

现在，应该不会再有来自 grequests 的警告了。
