python3 AttributeError: 'NoneType' object has no attribute 'split'


 1 from wsgiref.simple_server import make_server
 2  
 3 def RunServer(environ, start_response):
 4     start_response('200 ok',[('Content-Type','text/html')])
 5     return '<h1>Hello world</h1>'
 6 
 7 if __name__ == '__main__':
 8     httpd = make_server('127.0.0.1',9000,RunServer)
 9     print('servering HTTP on port 9000')
10     httpd.serve_forever()
Code

运行时报错:

self.status.split(' ',1)[0], self.bytes_sent
AttributeError: 'NoneType' object has no attribute 'split'

 

解决办法如下:

return ['<h1>Hello world</h1>'.encode('utf-8'),]
