Question

我的代码只需要通过代理连接到网页页面，但是当到达＆＃34; urllib2.urlopen＆＃34;时，总是会收到以下错误：句：

log( string nameValue) {
    attrs::mutable_constant< string > Name(nameValue);
    logger::get().add_attribute("Name", Name);
    Name.set(nameValue);
    cout << "name is: " << Name;
}

在Anaconda中运行Python 2.7，Windows 7 64位。

我的代码：

Traceback (most recent call last):

您可以使用urllib2.ProxyHandler，试试这个：

def urllib2_HTTP_test():
    proxy = urllib2.ProxyHandler({'http': '<proxy>:<port>'})
    opener = urllib2.build_opener(proxy)
    urllib2.install_opener(opener)
    status = urllib2.urlopen("http://www.python.org:80").getcode()
    assert status == 200

或使用pycurl，因为我更喜欢这样的东西：

import pycurl

def pycurl_HTTP_test(url, proxy, proxy_usr):
    c = pycurl.Curl()
    c.setopt(c.URL, url)
    c.setopt(pycurl.PROXY, proxy) #<-- ex. 'http://proxy:port'
    c.setopt(pycurl.PROXYUSERPWD, proxy_usr) #<-- ex. 'usr:pass'
    c.setopt(c.FAILONERROR, True)
    c.setopt(pycurl.VERBOSE, False)
    c.setopt(pycurl.FOLLOWLOCATION, 1)
    try:
        c.perform()
    except pycurl.error, error:
        errno, errstr = error
        print 'An error occurred: ', errstr
    status = c.getinfo(pycurl.HTTP_CODE)
    assert status == 200

if __name__ == "__main__":
    url = "http://www.python.org:80"
    proxy = 'http://proxy:port'
    proxy_usr = 'usr:pass'
    pycurl_HTTP_test(url, proxy, proxy_usr)
