Cherrypy _cp_dispatch奇怪的行爲與URL沒有結尾斜槓：POST然後GET

我正在用_cp_dispatch測試CherryPy。但是，當我發送1個單獨帖子時，_cp_dispatch被調用兩次，而不是一次。首先爲預期的職位，然後第二次與一個get：爲什麼？Cherrypy _cp_dispatch奇怪的行爲與URL沒有結尾斜槓：POST然後GET

的代碼：

import os 
import cherrypy 

class WebServerApp: 

    def __init__(self): 
     self.index_count = 0 
     self.cpdispatch_count = 0 

    def __del__(self): 
     self.exit() 

    def _cp_dispatch(self, vpath): 
     self.cpdispatch_count += 1 
     cherrypy.log.error('_cp_dispatch: ' + str(vpath) + ' - index count:' + str(self.cpdispatch_count)) 

     if len(vpath) == 0: 
      return self 

     if len(vpath) == 2: 
      vpath.pop(0) 
      cherrypy.request.params['id'] = vpath.pop(0) 
      return self 
     return vpath 

    @cherrypy.expose 
    def index(self, **params): 
     try: 
      self.index_count += 1 
      cherrypy.log.error('Index: received params' + str(params) + ' - index count:' + str(self.index_count)) 
     except Exception as e: 
      cherrypy.log.error(e.message) 

    def exit(self): 
     cherrypy.log.error('Exiting') 

    exit.exposed = True 

ws_conf = os.path.join(os.path.dirname(__file__), 'verybasicwebserver.conf') 
if __name__ == '__main__': 
    cherrypy.quickstart(WebServerApp(), config=ws_conf)

的配置文件：

r = requests.post("http://127.0.0.1:1025/id/12345")

表示cp_dispatch日誌結果被稱爲3次：1在

[global] 
server.socket_host = "127.0.0.1" 
server.socket_port = 1025 
server.thread_pool = 10 
log.screen = True 
log.access_file = "/Users/antoinebrunel/src/Rankings/log/cherrypy_access.log" 
log.error_file = "/Users/antoinebrunel/src/Rankings/log/cherrypy_error.log"

與請求的交啓動和兩次郵政

任何想法爲什麼_cp_dispatch被調用兩次的單個帖子？

- 編輯我懷疑一些301重定向在內部進行，因爲它出現在日誌中。
