TornadoHTTPClient 对tornado.curl_httpclient.CurlAsyncHTTPClient的封装, 支持cookie
python setup.py installTornadoHTTPClient的get方法可以发起一个get请求
from tornado import gen
from tornado.ioloop import IOLoop
from tornadohttpclient import TornadoHTTPClient
# 实例化
http = TornadoHTTPClient()
@gen.coroutine
def get():
# 发出get请求
response = yield http.get("http://www.linuxzen.com")
print(response.body)
# 异步发出请求
IOLoop.instance().run_async(get)from tornado import gen
from tornado.ioloop import IOLoop
from tornadohttpclient import TornadoHTTPClient
# 实例化
http = TornadoHTTPClient()
@gen.coroutine
def run():
response = yield http.upload("http://paste.linuxzen.com", "img",
"img_test.png", callback=callback)
print("打开图片链接", end=" ")
print(response.effective_url)
# 异步发出请求
IOLoop.instance().run_async(run)TornadoHTTPClient 的 get/post方法的第二个参数data可以定义请求时传递的参数data的类型为字典或者((key, value), )类型的元组或列表,例如使用百度搜索TornadoHTTPClient
from tornado import gen
from tornado.ioloop import IOLoop
from tornadohttpclient import TornadoHTTPClient
# 实例化
http = TornadoHTTPClient()
@gen.coroutine
def run():
response = yield http.get("http://www.baidu.com/s", (("wd", "tornado"),))
print(response.effective_url)
# 异步发出请求
IOLoop.instance().run_async(run)以上也使用与POST方法, 比如登录网站
from tornado import gen
from tornado.ioloop import IOLoop
from tornadohttpclient import TornadoHTTPClient
# 实例化
http = TornadoHTTPClient()
@gen.coroutine
def run():
yield http.post("http://ip.or.domain/login", (("username", "cold"), ("password", "pwd")))
# 异步发出请求
IOLoop.instance().run_async(run)from tornadohttpclient import TornadoHTTPClient
http = TornadoHTTPClient()
http.set_user_agent( "Mozilla/5.0 (X11; Linux x86_64)"\
" AppleWebKit/537.11 (KHTML, like Gecko)"\
" Chrome/23.0.1271.97 Safari/537.11")
# 后续的请求都会使用此 User-Agent 头
# ...TornadoHTTPClient 的get/post方法的 headers关键字参数可以自定额外的HTTP头信息, 参数类型为一个字典
指定User-Agent头
from tornado import gen
from tornado.ioloop import IOLoop
from tornadohttpclient import TornadoHTTPClient
# 实例化
http = TornadoHTTPClient()
@gen.coroutine
def run():
headers = dict((("User-Agent",
"Mozilla/5.0 (X11; Linux x86_64)"\
" AppleWebKit/537.11 (KHTML, like Gecko)"\
" Chrome/23.0.1271.97 Safari/537.11"), ))
yield http.get("http://www.linuxzen.com", headers=headers)
# 异步发出请求
IOLoop.instance().run_async(run)TornadoHTTPClient 的set_proxy方法可以设置代理, 其接受四个参数, 分别是代理的 主机名/ip 代理的端口 代理用户名 代理用户密码, 如无认证只传前两个即可, unset_proxy可以取消代理
from tornado import gen
from tornado.ioloop import IOLoop
from tornadohttpclient import TornadoHTTPClient
# 实例化
http = TornadoHTTPClient()
@gen.coroutine
def run():
http.set_proxy("127.0.0.1", 8087)
response = yield http.get("http://shell.appspot.com", callback=callback)
print response.body
http.unset_proxy()
# 异步发出请求
IOLoop.instance().run_async(run)TornadoHTTPClient会自动记录和装载Cookie, 可以通过 TornadoHTTPClient实例属性 cookie 获取Cookie
