正如你所看到的,我使用开罐器访问不同的网站,使用饼干罐。我可以设置一个头文件,这样每次网站时,头文件都被应用了吗?
As you can see, I use opener to visit different websites, using a cookie jar. Can I set a header so that each time a website is it, the header is applied?
推荐答案您可以直接添加头文件到由 build_opener 返回的 OpenerDirector 对象。从 urllib2文档中的最后一个示例:
You can add the headers directly to the OpenerDirector object returned by build_opener. From the last example in the urllib2 docs:
OpenerDirector automatically adds a User-Agent header to every Request. To change this:
import urllib2 opener = urllib2.build_opener() opener.addheaders = [('User-agent', 'Mozilla/5.0')] opener.open('www.example/')
另外,请注意添加一些标准标题(Content-Length,Content-Type和Host)当请求被传递给urlopen()(或OpenerDirector.open())时。
Also, remember that a few standard headers (Content-Length, Content-Type and Host) are added when the Request is passed to urlopen() (or OpenerDirector.open()).
