Python3 urllib.parse

urllib.parse分为URL parsing and URL quoting，即网址解析和网址引用。

URL解析函数专注于将URL字符串拆分为其组件，或将URL组件组合到URL字符串中。

urllib.parse.urlparse(urlstring, scheme='', allow_fragments=True) >>> from urllib.parse import urlparse >>> o = urlparse('http://www.cwi.nl:80/~guido/Python.html') >>> o ParseResult(scheme='http', netloc='www.cwi.nl:80', path='/~guido/Python.html', params='', query='', fragment='') >>> o.scheme 'http' >>> o.port 80 >>> o.geturl() 'http://www.cwi.nl:80/~guido/Python.html' >>> from urllib.parse import urlparse >>> urlparse('//www.cwi.nl:80/~guido/Python.html') ParseResult(scheme='', netloc='www.cwi.nl:80', path='/~guido/Python.html', params='', query='', fragment='') >>> urlparse('www.cwi.nl/~guido/Python.html') ParseResult(scheme='', netloc='', path='www.cwi.nl/~guido/Python.html', params='', query='', fragment='') >>> urlparse('help/Python.html') ParseResult(scheme='', netloc='', path='help/Python.html', params='', query='', fragment='')

urllib.parse.urlsplit(urlstring, scheme='', allow_fragments=True) 使用方法同上

合并URL

urll.parse.urlencode()

urllib.parse.urlunsplit(parts)

urllib.parse.urljoin(base, url, allow_fragments=True) >>> from urllib.parse import urljoin >>> urljoin('http://www.cwi.nl/~guido/Python.html', 'FAQ.html') 'http://www.cwi.nl/~guido/FAQ.html'
