一個類似字節的對象是不需要'str'

我想爲Flask創建一個本地HTTP服務器。一個類似字節的對象是不需要'str'

服務器啓動成功，但是當我嘗試運行本地主機：5000在網頁瀏覽器我得到這個錯誤

class webserverhandler(BaseHTTPRequestHandler): 

def do_GET(self): 
    try: 
     if self.path.endswith("/"): 
      self.send_response(200) 
      self.send_header('Content-Type','text/html') 
      self.end_headers() 

      output="" 
      output+="<html><body>Hello</body></html>" 

      self.wfile.write(output) 
      print (output) 
      return 

    except IOError: 
     self.send_error(404,"File Not Found %s" % self.path) 


def main(): 
try: 
    port=5000 
    server=HTTPServer(('',port),webserverhandler) 
    print ("webserver running on %s" % port) 
    server.serve_forever() 


except KeyboardInterrupt: 
    server.socket.close()

self._sock.sendall(b) 
TypeError: a bytes-like object is required, not 'str'

任何人都可以幫我嗎？

你有沒有試過'self.wfile.write（output.encode（））'？ –

您可以將output可變編碼成bytes_object這樣的：

self.wfile.write(output.encode())

看來你使用的是Python3，默認情況下字符串文字是unicode（str）對象。使用b -prefix

output = b"" 
output += b"<html><body>Hello</body></html>"

創建bytes -object。
