tornado 入门之（异步、同步实现-ab测压）酱酱仙的博客【6】

根据tornado官方示例代码，做对百度网站异步访问的ab测试

这种异步方式适用于爬虫 http://www.tornadoweb.org/en/stable/networking.html

同步测试代码：

import tornado.web
import tornado.ioloop
import tornado.httpclient

class IndexHandler(tornado.web.RequestHandler):
    def get(self):
        wd = self.get_argument('wd')
        client = tornado.httpclient.HTTPClient()
        # https://www.baidu.com/s?wd=python
        response = client.fetch('https://www.baidu.com/s?wd=%s' %wd)
        print(response)
        self.write('同步测试')

def make_app():
    return tornado.web.Application(handlers =[
        (r'/',IndexHandler),
    ])

if __name__ == '__main__':
    app = make_app()
    app.listen(8888)
    tornado.ioloop.IOLoop.current().start()

异步测试代码：

import tornado.web
import tornado.ioloop
import tornado.httpclient

class IndexHandler(tornado.web.RequestHandler):
    @tornado.web.gen.coroutine
    def get(self):
        wd = self.get_argument('wd')
        client = tornado.httpclient.AsyncHTTPClient()
        # https://www.baidu.com/s?wd=python
        response = yield client.fetch('https://www.baidu.com/s?wd=%s' %wd)
        print(response)
        self.write('异步测试')

def make_app():
    return tornado.web.Application(handlers =[
        (r'/',IndexHandler),
    ])

if __name__ == '__main__':
    app = make_app()
    app.listen(8888)
    tornado.ioloop.IOLoop.current().start()
