Python http.client getaddrinfo失敗

我正在使用http.client嘗試從主機讀取xml文件。我會使用urllib2，但是我得到一個BadStatusLine，因爲在xml頭部之前有3個空格（我無法改變它）。這就是爲什麼我正在嘗試這條路線。Python http.client getaddrinfo失敗

我現在卡住了，我不斷收到錯誤（getaddrinfo失敗）。

下面是我的代碼，下面是回溯。有人可以提醒我做錯了什麼嗎？

僅供參考的，關於瀏覽器的工作原理地址爲http://machineIP:81/command=AB&time=2013-06-02

我沒有問題，訪問XML的方式。

感謝您提前提供任何幫助！

代碼：

import http.client 
import datetime 

IP = input("Enter the IP: ") 
PT = str(81) 
F1 = datetime.date.today() - datetime.timedelta(days=2) 

print("Reading File...") 
html = http.client.HTTPConnection('http://' + IP , port= PT) 
html.request("GET", '/command=AB&time=' + str(F1)) 
r1 = html.getresponse() 

print("Writing to file...") 
out = r1.read() 
f = open('Files/' + IP + '-' + str(F1) + '.xml', 'wb') 
print("Writing to file...") 
f.write(out) 
f.close() 
print("Done.")

嘗試刪除'的 'http：//''您前面加上到IP。 – ejno

這工作，但現在我再次得到一個badstatusline？我無法更改我得到的文件，並且它通過瀏覽器正常工作。有任何想法嗎？ – mad5245

所以我想通了。爲了避免badStatusLines和其他類似的錯誤，我使用了socket/urllib2。這樣你就可以從網頁獲得原始信息，而不必擔心任何你無法控制的問題。

這裏是添加了套接字的代碼片段。

socket.setdefaulttimeout(timeout) 
req = urllib2.Request(host) 
response = urllib2.urlopen(req)

這是迄今爲止我發現的唯一成功。感謝ejno讓我走上正軌。

Windows在最後（'\ n'）添加了一個「新行」字符，它與unix Windows = CRLF不同。我正在閱讀Windows ASCII文本文件並遇到類似的問題。如果我只是將文件讀入列表並打印出來，它會在兩者之間添加一條空行。這給了我一個線索。我使用的是建立在urllib3之上的Requests庫。

如果我使用

r = requests.get(url.strip('\n'))

它工作得很好。

r = requests.get(url)

彈出有錯誤
