gunicorn和websockets

Question

我試圖讓http://www.gelens.org/code/gevent-websocket/運行並不斷收到以下錯誤。

socket_id=1 already closed. 
    result = self._run(*self.args, **self.kwargs) 
    File "/home/walt/virtualenv/ws/local/lib/python2.7/site-packages/gevent/pywsgi.py", line 571, in handle 
    handler.handle() 
    File "/home/walt/virtualenv/ws/local/lib/python2.7/site-packages/gevent/pywsgi.py", line 180, in handle 
    result = self.handle_one_request() 
    File "/home/walt/virtualenv/ws/local/lib/python2.7/site-packages/gevent/pywsgi.py", line 314, in handle_one_request

    return self._handle_websocket() 
    File "/home/walt/virtualenv/ws/local/lib/python2.7/site-packages/geventwebsocket/handler.py", line 50, in _handle_websocket

    log.write(self.format_request() + '\n') 
AttributeError: 'Logger' object has no attribute 'write'

Answer 1

運行gunicorn -k "geventwebsocket.gunicorn.workers.GeventWebSocketWorker" example:app示例時，我得到了與gevent-websocket 0.3.4和gevent 0.13.6相同的錯誤。

問題來自gevent和gunicorn之間的期望不匹配。 Gevent的pywsgi模塊需要一個實現了write方法的記錄器對象，例如文件對象，標準輸出等。然而，Gunicorn傳入一個包含方法（調試，信息，錯誤，關鍵，警告等）的對象。

問題代碼pywsgi：

def log_request(self): 
    log = self.server.log 
    if log: 
     log.write(self.format_request() + '\n') 

爲了解決這個問題我自己，我砍死了在GEVENT的叉行，並將其更改爲以下內容：

def log_request(self): 
    log = self.server.log 
    if log: 
     if hasattr(log, "info"): 
      log.info(self.format_request() + '\n') 
     else: 
      log.write(self.format_request() + '\n') 

Answer 2

請使用GEVENT和GEVENT-的WebSocket PyPI上的最新版本。

Answer 3

使用@ bkad的

代碼並添加到主主應用程序文件

def log_request(self): 
    log = self.server.log 
    if log: 
     if hasattr(log, "info"): 
      log.info(self.format_request() + '\n') 
     else: 
      log.write(self.format_request() + '\n') 

import gevent 
gevent.pywsgi.WSGIHandler.log_request = log_request 

到赫德，這樣我就不必修改第三方庫。
