pyinstaller 打包无窗口python http.server无法启动

最近在写一个简单的文件服务器用来访问静态文件，遇到在pyinstaller无窗口模式下无法启动的问题，记录一下解决方案。

• 原因：http.server需要将记录输出到窗口，而pyinstaller打包无窗口模式没有地方输出

  class BaseHTTPRequestHandler(socketserver.StreamRequestHandler):
      ...
  
      def log_message(self, format, *args):
          """Log an arbitrary message.
  
          This is used by all other logging functions.  Override
          it if you have specific logging wishes.
  
          The first argument, FORMAT, is a format string for the
          message to be logged.  If the format string contains
          any % escapes requiring parameters, they should be
          specified as subsequent arguments (it's just like
          printf!).
  
          The client ip and current date/time are prefixed to
          every message.
  
          Unicode control characters are replaced with escaped hex
          before writing the output to stderr.
  
          """
  
          message = format % args
          sys.stderr.write("%s - - [%s] %s\n" %
                           (self.address_string(),
                            self.log_date_time_string(),
                            message.translate(self._control_char_table)))
  
  

• 解决方案：

  import os
  import http.server
  import socketserver
  
  DIRECTORY = os.path.join(os.path.abspath(os.path.dirname(__file__)), "static", "js")
  PORT = 38121
  
  class SimpleHTTPRequestHandlerWithDirectory(http.server.SimpleHTTPRequestHandler):
  
      def __init__(self, *args, **kwargs):
          super().__init__(*args, directory=DIRECTORY, **kwargs)
  
      # 重写这个防止服务打包后起不来
      def log_message(self, format, *args):
          pass
  
  def run_server(port=PORT):
      # 创建并启动服务器
      try:
          with socketserver.TCPServer(("", port), SimpleHTTPRequestHandlerWithDirectory) as httpd:
              # print("Serving at port", port)
              httpd.serve_forever()
      except OSError as e:
          print(e)
          pass
  
  if __name__ == '__main__':
      run_server()
