rya*_*yan 7 python urllib urllib2
在Python中,我可以使用urllib2(和urllib)打开外部URL,例如Google.但是,我在打开localhost URL时遇到了问题.我有一个在端口8280上运行的python SimpleHTTPServer,我可以使用http:// localhost:8280 /成功浏览.
python -m SimpleHTTPServer 8280
值得注意的是,我正在运行Ubuntu,它运行CNTLM以处理对我们公司Web代理的身份验证.因此,wget实际上并不适用于localhost,所以我不认为这是一个urllib问题!
测试脚本(test_urllib2.py):
import urllib2
print "Opening Google..."
google = urllib2.urlopen("http://www.google.com/")
print google.read(100)
print "Google opened."
print "Opening localhost..."
localhost = urllib2.urlopen("http://localhost:8280/")
print localhost.read(100)
print "localhost opened."
输出:
$ ./test_urllib2.py
Opening Google...
<!doctype html><html><head><meta http-equiv="content-type" content="text/html; charset=ISO-8859-1"><
Google opened.
Opening localhost...

httplib.BadStatusLine
解决方案:问题确实是因为我在我们的企业Web代理后面使用CNTLM(具体原因导致了我无法确定的问题).解决方案是使用ProxyHandler:
proxy_support = urllib2.ProxyHandler({})
opener = urllib2.build_opener(proxy_support)
print opener.open("http://localhost:8380/").read(100)
由于loki2302指着我这里.
检查问题是否真的出在打开本地主机上，或者 JBoss 是否给出了无效响应（浏览器以某种方式解决了问题）：
wget http://localhost:8280/你可以尝试运行一个简单的 Python HTTP 服务器来测试 JBoss 以外的东西：
python -m SimpleHTTPServer 8280
