怪異的「STR」對象不是可調用的蟒蛇

好傢伙在我的代碼我得到這個堆棧：怪異的「STR」對象不是可調用的蟒蛇

Traceback (most recent call last): 
    File "main.py", line 30, in <module> 
    print nova.put_server_metadata("48f366bd-e9c9-47b5-a41f-ca9bcac2d945","labeltest","2.0") 
TypeError: 'str' object is not callable

，但我不知道，這個錯誤，我試圖把打印我的方法「put_server_metadata」裏面，但它不是在屏幕上打印時，按照代碼：

主要類：

import novaapiclient 
import novaauth 

if __name__ == "__main__": 

    nova = novaapiclient.NovaAPIClient("http://192.168.100.142:35357/v2.0/tokens") 

    nova.makeAuth("adminUser", "secretword", "2ad1fc162c254e59bea043560b7f73cb") 

    print nova.put_server_metadata("48f366bd-e9c9-47b5-a41f-ca9bcac2d945","labeltest","2.0")

而且我put_server_metadata代碼：

def put_server_metadata(self, serv_id, label, version): 
     if self.auth.isAuthed(): 

      c = pycurl.Curl() 
      printer = cStringIO.StringIO() 

      url = self.auth.getComputeURL() + "/servers/%s/metadata" % serv_id 
      json_put = file('json_server_put_metadata.json','r+w') 
      new_js = str(self.put_server_metadata) % (label, version) 

      json_put.seek(0) 
      json_put.write(new_js) 
      json_put.truncate() 
      json_put.close() 

      json_to_send = file('json_server_put_metadata.json','r+w') 
      siz = os.path.getsize("json_server_put_metadata.json") 

      tok = str(self.auth.getAuthToken()) 

      final_tok = "X-Auth-Token: %s" % tok 
      content_len = "Content-length: %d" % siz 
      cont_type = "Content-Type: application/json" 
      accept = "Accept: application/json" 

      c.setopt(pycurl.URL, url) 
      c.setopt(pycurl.PUT, 1) 
      c.setopt(pycurl.HTTPHEADER, [final_tok, cont_type, accept, content_len]) 
      c.setopt(pycurl.INFILE, json_to_send) 
      c.setopt(pycurl.INFILESIZE, siz) 
      c.setopt(pycurl.WRITEFUNCTION, printer.write) 
      c.setopt(pycurl.VERBOSE, 1) 
      c.perform() 
      c.close() 

      return printer.getvalue() 
     else: 
      return "Not authorized"

我的猜測是'nova.put_server_metadata'正在反彈到你沒有顯示的代碼中的字符串。 – geoffspear 2012-04-27 12:39:08

從錯誤消息看來，put_server_metadata被用作方法和字符串。同時下列提示：

def put_server_metadata(self, serv_id, label, version): # a method 
    ... 
    new_js = str(self.put_server_metadata) % ... # not consistent with 
               # put_server_metadata being a method

如果是你的話，我會通過爲put_server_metadata所有出現的代碼進行搜索，並將從那裏。

是的，我已更改屬性的名稱，它的工作原理，謝謝！ – guisantogui 2012-04-27 13:00:16
