Python使用指定端口进行http请求的例子

class SourcePortAdapter(HTTPAdapter): """"Transport adapter" that allows us to set the source port.""" def __init__(self, port, *args, **kwargs):  self.poolmanager = None  self._source_port = port  super().__init__(*args, **kwargs) def init_poolmanager(self, connections, maxsize, block=DEFAULT_POOLBLOCK, **pool_kwargs):  self.poolmanager = PoolManager(   num_pools=connections, maxsize=maxsize,   block=block, source_address=('', self._source_port))s = requests.Session()s.mount('https://baidu.com', SourcePortAdapter(54321))s.get('https://baidu.com')

c = pycurl.Curl()c.setopt(c.URL, 'https://curl.haxx.se/dev/')c.setopt(c.LOCALPORT, 54321)c.setopt(c.LOCALPORTRANGE, [52314,56321,5532])c.perform()c.close()

curl --local-port 12520 http://baidu.com
