我正在使用实现 WSGI 请求和响应的 Bottle 框架,并且由于单线程问题,我将服务器更改为 PythonWSGIServer 并使用 Apache bench 进行了测试,但结果包括与此问题类似的错误损坏管道如何防止 errno 32 损坏管道?. 我已经尝试了答案,但无济于事。

  Traceback (most recent call last):
  File "/Library/Python/2.7/site-packages/paste/httpserver.py", line 1068, in process_request_in_thread
    self.finish_request(request, client_address)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 323, in finish_request
    self.RequestHandlerClass(request, client_address, self)
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 641, in __init__
    self.finish()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 694, in finish
    self.wfile.flush()
  File "/System/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/socket.py", line 303, in flush
    self._sock.sendall(view[write_offset:write_offset+buffer_size])
error: [Errno 32] Broken pipe

服务器代码如下所示,我不知道如何使用线程池改善连接?

from paste import httpserver

    @route('/')
    def index():
        connection = pymongo.MongoClient(connectionString)
        db = connection.test
        collection = db.test
        return str(collection.find_one())

    application = default_app()
    httpserver.serve(application, host='127.0.0.1', port=8082)

问题在于 WSGIServer 是同步服务器,不适用于高并发用户同时发送请求。为了绕过这些回退,有很多第三方框架可以使用。其中流行的是 Gevent greenlet 库、Tornado 和 CherryPy。它们都基于事件驱动和异步方法,使它们能够处理多个并发用户。
