Python http.client getaddrinfo失败

我正在使用http.client尝试从主机读取xml文件。我会使用urllib2，但是我得到一个BadStatusLine，因为在xml头部之前有3个空格（我无法改变它）。这就是为什么我正在尝试这条路线。Python http.client getaddrinfo失败

我现在卡住了，我不断收到错误（getaddrinfo失败）。

下面是我的代码，下面是回溯。有人可以提醒我做错了什么吗？

仅供参考的，关于浏览器的工作原理地址为http://machineIP:81/command=AB&time=2013-06-02

我没有问题，访问XML的方式。

感谢您提前提供任何帮助！

代码：

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.")

尝试删除'的 'http：//''您前面加上到IP。 – ejno

这工作，但现在我再次得到一个badstatusline？我无法更改我得到的文件，并且它通过浏览器正常工作。有任何想法吗？ – mad5245

所以我想通了。为了避免badStatusLines和其他类似的错误，我使用了socket/urllib2。这样你就可以从网页获得原始信息，而不必担心任何你无法控制的问题。

这里是添加了套接字的代码片段。

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

这是迄今为止我发现的唯一成功。感谢ejno让我走上正轨。

Windows在最后（'\ n'）添加了一个“新行”字符，它与unix Windows = CRLF不同。我正在阅读Windows ASCII文本文件并遇到类似的问题。如果我只是将文件读入列表并打印出来，它会在两者之间添加一条空行。这给了我一个线索。我使用的是建立在urllib3之上的Requests库。

如果我使用

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

它工作得很好。

r = requests.get(url)

弹出有错误
