##自带的urllib/urllib2库

URL_IP = 'http://127.0.0.1:8000/ip'URL_GET = 'http://127.0.0.1:8000/get'def use_simple_urllib2():    response = urllib2.urlopen(URL_IP)    print('>>>>Response Headers:')    print(response.info())    print('>>>>Response Body:')    print(''.join([line for line in response.readlines()]))def use_params_urllib2():    params = urllib.urlencode({
   'param1':'Hello','param2':'World'})    print params    response = urllib2.urlopen('?'.join([URL_GET,'%s'])%params)    print('>>>>Response Headers:')    print(response.info())    print('>>>>Status Code:')    print(response.getcode())    print('>>>>Response Body:')    print(''.join([line for line in response.readlines()]))复制代码

##第三方requests库

import jsonimport requestsimport timeURL = 'https://api.github.com'def build_url(endpoint):    return '/'.join([URL,endpoint])def better_print(json_str):    return json.dumps(json.loads(json_str),indent=4)def reuqest_method():    t1 = time.time()    response = requests.get(build_url('users/HuYaming520'))    t2 = time.time()    print('请求耗时%ss'%(t2-t1))#通过status_code判断请求是否成功：200成功    print(response.status_code,response.reason)#通过text获取请求返回数据    print(better_print(response.text))def params_request():    t1 = time.time()    response = requests.get(build_url('users'),params={
   'since':11})    t2 = time.time()    print('请求耗时%ss'%(t2-t1))    print(better_print(response.text))    print(response.request.headers)    print(response.url)if __name__ == '__main__':    print('请求中...')    reuqest_method()    print('请求完成...')复制代码
