python flask如何解决同时请求同一个请求的阻塞问题？

Question

fromflaskimportFlask
importtime
app=Flask(__name__)
@app.route('/test)
defsayHello():
time.sleep(10)
return'hello'
@app.route('/hi')
defsayHi():
return'hi'
if__name__=='__main__'
app.run(debug=True，threaded=True)
如上述代码所示，倘若在浏览器打开多张空白页，然后都去请求127.0.0.1:5000/test，会发现进入了阻塞状态,每一张页面会等待它之前的那个请求结束后在加载当前页面。但是去访问127.0.0.1:5000/hi却不会收到前面那个网址的影响
所以，我应该如何实现我多个请求去访问127.0.0.1:5000/test这个不受其他的影响，能够同时加载？

可以用gevet啊fromgeventimportmonkeyfromgevent.pywsgiimportWSGIServermonkey.patch_all()fromflaskimportFlaskimporttimeapp=Flask(__name__)@app.route('/test',methods=['GET'])defsayHello():time.sleep(10)return'hello'@app.route('/hi',methods=['GET'])defsayHi():return'hi'if__name__=='__main__':http_server=WSGIServer(('',5000),app)http_server.serve_forever()测试结果：127.0.0.1--[2017-12-1222:35:10]"GET/test/HTTP/1.1"2001260.000000127.0.0.1--[2017-12-1222:35:11]"GET/test/HTTP/1.1"2001260.000000127.0.0.1--[2017-12-1222:35:11]"GET/test/HTTP/1.1"2001260.000000127.0.0.1--[2017-12-1222:35:12]"GET/test/HTTP/1.1"2001260.000000127.0.0.1--[2017-12-1222:35:12]"GET/test/HTTP/1.1"2001260.000998127.0.0.1--[2017-12-1222:35:13]"GET/test/HTTP/1.1"2001260.001001127.0.0.1--[2017-12-1222:35:14]"GET/test/HTTP/1.1"2001260.000000127.0.0.1--[2017-12-1222:35:14]"GET/test/HTTP/1.1"2001260.001014127.0.0.1--[2017-12-1222:35:15]"GET/test/HTTP/1.1"2001260.001000127.0.0.1--[2017-12-1222:35:15]"GET/test/HTTP/1.1"2001260.000000127.0.0.1--[2017-12-1222:35:18]"GET/asyn/HTTP/1.1"20012610.000392

我认为访问hi也会受到test的影响。言归正传，你可以使用gevent，在文件开头：fromgeventimportmonkeymonkey.patch_all()
