GET

TornadoHTTPClient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)

IOLoop.instance().run_sync(get)

上传文件

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)

IOLoop.instance().run_sync(run)

给请求传递参数

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)

IOLoop.instance().run_sync(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")))

IOLoop.instance().run_sync(run)

设置User-Agent

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
# ...

指定HTTP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)

IOLoop.instance().run_sync(run)

使用代理

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()

IOLoop.instance().run_sync(run)

Cookie

TornadoHTTPClient会自动记录和装载Cookie, 可以通过 TornadoHTTPClient实例属性 cookie 获取Cookie
