windows tornado+flask发布问题

Question

from flask import Flask,request,render_template
from tornado.wsgi import WSGIContainer
from tornado.httpserver import HTTPServer
from tornado.ioloop import IOLoop

app = Flask(name)
@app.route(’/’, methods=[‘GET’])
def index(name = None):
if request.method == ‘GET’:
name = "WEB SERVER"
return render_template(‘index.html’,name=name)

if name == ‘main’:
try:
http_server = HTTPServer(WSGIContainer(app))
http_server.listen(5000)
IOLoop.instance().start()
app.debug = True
#app.run(host=‘0.0.0.0’, port=80, debug=True)
except:
pass

运行这个文件，也不提示错误，系统直接退出了，
运行后程序直接退出了，无法启动多并发处理
改成那个注释的语句：
app.run(host=‘0.0.0.0’, port=80, debug=True)
是没有问题的

你好

参考下这个文章，我当时没遇到，你看看这个是否可以

你好

if name == ‘main’:

 if __name__ == "__main__":
 
这种错误太低级了。本身都可以看出来的，或者对比下源码

  源码里是if __name__ == "__main__":
  只是复制到提问里，少了两个下划线，代码是我直接从你的git上全文件复制的，所以不是这个问题，我有编写了一个最简单的文件，如下，
  from flask import Flask, request, render_template
  from tornado.wsgi import WSGIContainer
  from tornado.httpserver import HTTPServer
  from tornado.ioloop import IOLoop
  
  app = Flask(__name__)
  
  
  @app.route('/', methods=['GET'])
  def index(name=None):
      if request.method == 'GET':
          name = "WEB SERVER"
          return render_template('index.html', name=name)
  
  
  def main():
      http_server = HTTPServer( WSGIContainer(app) )
      http_server.listen( 5000 )
      IOLoop.instance().start()
  
  if __name__ == "__main__":
      try:
          import sys
          sys.exit( main() )
      except Exception as e:
          import traceback
          traceback.print_exc()
  
  
  也是同样的错误，所以我怀疑是环境的问题，但是不知道是什么问题，网上查了很多资料，没看懂，错误截图我是实在截取不下来，
  所以把错误复制出来，您给看看，就差最后一步发布了，因为我这里的客户用的服务器是win系统，
  上面还有其它服务软件，没法装linux系统的
  
  错误提示如下：
