python - Flask 在被请求太频繁时给出 "error 32 broken pipe"

Question

我写了一个非常简单的 flask 服务器。此服务器响应 GET 并返回我的 home.html。 我在 127.0.0.1:5000 上访问该站点

到目前为止一切都很好。

但是，如果我尽可能快地多次按“刷新”(在我的计算机上为 Command+R)几秒钟，那么，我的 flask 会出现此错误并发生故障。

Exception in thread Thread-1: Traceback (most recent call last): File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 801, in bootstrap_inner self.run() File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/threading.py", line 754, in run self.__target(*self.__args, **self.__kwargs) File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 659, in inner srv.serve_forever() File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 499, in serve_forever HTTPServer.serve_forever(self) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 238, in serve_forever self._handle_request_noblock() File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 297, in _handle_request_noblock self.handle_error(request, client_address) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 295, in _handle_request_noblock self.process_request(request, client_address) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 321, in process_request self.finish_request(request, client_address) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 334, in finish_request self.RequestHandlerClass(request, client_address, self) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/SocketServer.py", line 655, in __init self.handle() File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 216, in handle rv = BaseHTTPRequestHandler.handle(self) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/BaseHTTPServer.py", line 340, in handle self.handle_one_request() File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 251, in handle_one_request return self.run_wsgi() File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 193, in run_wsgi execute(self.server.app) File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 184, in execute write(data) File "/usr/local/lib/python2.7/site-packages/werkzeug/serving.py", line 152, in write self.send_header(key, value) File "/usr/local/Cellar/python/2.7.11/Frameworks/Python.framework/Versions/2.7/lib/python2.7/BaseHTTPServer.py", line 401, in send_header self.wfile.write("%s: %s\r\n" % (keyword, value)) IOError: [Errno 32] Broken pipe

我相信这就是发生的事情:当我的服务器试图将 html 传输到我的浏览器时，我按下了刷新并破坏了管道。所以我的服务器感到困惑然后给出错误。

如何解决这个问题？或者这个网站根本无法使用，因为任何不断询问我的页面的人都可以破坏我的网页。

谢谢!

您可以按照 this 中的建议尝试使用 app.run(threaded=True)所以回答。
