【错误记录/web.py】RuntimeError: generator raised StopIteration(in __iter__ raise StopIteration())

错误详情

• web.py版本0.40

  Traceback (most recent call last):
    File "/home/pi/.local/lib/python3.7/site-packages/web/httpserver.py", line 239, in __iter__
      raise StopIteration()
  StopIteration
  
  The above exception was the direct cause of the following exception:
  
  Traceback (most recent call last):
    File "/home/pi/.local/lib/python3.7/site-packages/cheroot/server.py", line 1280, in communicate
      req.respond()
    File "/home/pi/.local/lib/python3.7/site-packages/cheroot/server.py", line 1083, in respond
      self.server.gateway(self).respond()
    File "/home/pi/.local/lib/python3.7/site-packages/cheroot/wsgi.py", line 145, in respond
      for chunk in filter(None, response):
  RuntimeError: generator raised StopIteration

  添加最后两行

  def __iter__(self):
      # ...
      try:
          path = self.translate_path(self.path)
          etag = '"%s"' % os.path.getmtime(path)
          client_etag = environ.get("HTTP_IF_NONE_MATCH")
          self.send_header("ETag", etag)
          if etag == client_etag:
              self.send_response(304, "Not Modified")
              self.start_response(self.status, self.headers)
              return
      except OSError:
          pass  # Probably a 404
      except StopIteration: # 添加
          return # 添加
