httplib python/wxpython。襪子流錯誤

Question

我想檢查幾個網址，看他們是否回來，然後再進一步處理它們，我有self.myList中的URL列表，然後通過httplib HTTP連接運行這些URL以獲取響應，但是我從cmd中的httplib獲得了一大堆錯誤。

代碼工作，因爲我已經與下面的測試，它正確地回來，並設置在wx.TextCtrl值：

#for line in self.myList: 
      conn = httplib.HTTPConnection("www.google.com") 
      conn.request("HEAD", "/") 
      r1 = conn.getresponse() 
      r1 = r1.status, r1.reason 
      self.urlFld.SetValue(str(r1)) 

它只是似乎並不當我通過它的工作來自myList的超過1個網址。

for line in self.myList: 
      conn = httplib.HTTPConnection(line) 
      conn.request("HEAD", "/") 
      r1 = conn.getresponse() 
      r1 = r1.status, r1.reason 
      self.urlFld.SetValue(line + "\t\t" + str(r1)) 

我得到CMD的錯誤是

Traceback (most recent call last): 
File "gui_texteditor_men.py", line 96, in checkBtnClick 
conn.request("HEAD", "/") 
File "C:\Python27\lib\httplib.py", line 958, in request 
self._send_request(method, url, body, headers) 
File "C:\Python27\lib\httplib.py", line 992, in _send_request 
self.endheaders(body) 
File "C:\Python27\lib\httplib.py", line 954, in endheaders 
self._send_output(message_body) 
File "C:\Python27\lib\httplib.py", line 814, in _send_output 
self.send(msg) 
File "C:\Python27\lib\httplib.py", line 776, in send 
self.connect() 
File "C:\Python27\lib\httplib.py", line 757, in connect 
self.timeout, self.source_address) 
File "C:\Python27\lib\socket.py", line 553, in create_connection 
for res in getaddrinfo(host, port, 0, SOCK_STREAM): 
socket.gaierror: [Errno 11004] getaddrinfo failed 

編輯，使用更新裏urlparse代碼。我已經導入了urlparse。

for line in self.myList: 
      url = urlparse.urlparse(line) 
      conn = httplib.HTTPConnection(url.hostname) 
      conn.request("HEAD", url.path) 
      r1 = conn.getresponse() 
      r1 = r1.status, r1.reason 
      self.urlFld.AppendText(url.hostname + "\t\t" + str(r1)) 

與回溯，

C:\Python27\Coding>python gui_texteditor_men.py 
Traceback (most recent call last): 
File "gui_texteditor_men.py", line 97, in checkBtnClick 
conn = httplib.HTTPConnection(url.hostname) 
File "C:\Python27\lib\httplib.py", line 693, in __init__ 
self._set_hostport(host, port) 
File "C:\Python27\lib\httplib.py", line 712, in _set_hostport 
i = host.rfind(':') 
AttributeError: 'NoneType' object has no attribute 'rfind' 

我現在有www.google.com和www.bing.com在.txt文件，當它拋出這個錯誤。

編輯2 @綾，

看起來失敗，原因是2個網址之間的 「\ n」。我以爲我用.strip（）編碼去除「\ n」，但似乎沒有任何效果。

Failed on u'http://www.google.com\nhttp://www.bing.com' 
Traceback (most recent call last): 
File "gui_texteditor_men.py", line 99, in checkBtnClick 
conn.request("HEAD", url.path) 
File "C:\Python27\lib\httplib.py", line 958, in request 
self._send_request(method, url, body, headers) 
File "C:\Python27\lib\httplib.py", line 992, in _send_request 
self.endheaders(body) 
File "C:\Python27\lib\httplib.py", line 954, in endheaders 
self._send_output(message_body) 
File "C:\Python27\lib\httplib.py", line 814, in _send_output 
self.send(msg) 
File "C:\Python27\lib\httplib.py", line 776, in send 
self.connect() 
File "C:\Python27\lib\httplib.py", line 757, in connect 
self.timeout, self.source_address) 
File "C:\Python27\lib\socket.py", line 553, in create_connection 
for res in getaddrinfo(host, port, 0, SOCK_STREAM): 
socket.gaierror: [Errno 11004] getaddrinfo failed 

我又看看我.strip（）當我打開文件，

if dlg.ShowModal() == wx.ID_OK: 
     directory, filename = dlg.GetDirectory(), dlg.GetFilename() 
     self.filePath = '/'.join((directory, filename)) 
     self.fileTxt.SetValue(self.filePath) 
     self.urlFld.LoadFile(self.filePath) 
     self.myList = self.urlFld.GetValue().strip() 

，現在回跡與 「失敗的u'h'」

感謝

Answer 1

如果self.myList包含的URL列表，你不能直接在HTTPConnection構造像你這樣在這裏使用他們...

for line in self.myList: 
    conn = httplib.HTTPConnection(line) 
    conn.request("HEAD", "/") 

HTTPConnection構造函數應該只傳遞URL的主機名部分，並且請求方法應該被賦予路徑部分。你需要分析的東西，如網址...

import urlparse 

for line in self.myList: 
    url = urlparse.urlparse(line) 
    conn = httplib.HTTPConnection(url.hostname) 
    conn.request("HEAD", url.path) 

更新

您可以更改代碼...

for line in self.myList: 
    try: 
     url = urlparse.urlparse(line) 
     conn = httplib.HTTPConnection(url.hostname) 
     conn.request("HEAD", url.path) 
     r1 = conn.getresponse() 
     r1 = r1.status, r1.reason 
     self.urlFld.AppendText(url.hostname + "\t\t" + str(r1)) 
    except: 
     print 'Failed on %r' % line 
     raise 

...和包括全力輸出跑步呢？

更新＃2

我不太知道什麼self.fileTxt和self.urlFld應該做的，但如果你只是從self.filePath念臺詞，你只需要...

if dlg.ShowModal() == wx.ID_OK: 
    directory, filename = dlg.GetDirectory(), dlg.GetFilename() 
    self.filePath = '/'.join((directory, filename)) 
    self.myList = [line.strip() for line in open(self.filePath, 'r').readlines()]
