本篇主要记录下使用python的requests模块发送GET请求的实现代码.

向服务器发送get请求： 无参数时：r = requests.get(url) 带params时:r = requests.get(url,params=params) 带params和headers时：r = requests.get(url,params=params，headers=headers) 代码如下：

#coding=utf-8import unittestimport requestsclass GetTest(unittest.TestCase):    def setUp(self):        host = 'https://httpbin.org/'        endpoint = 'get'        self.url = ''.join([host, endpoint])    def test1(self):        u'''get无参数测试'''        r1 = requests.get(self.url)# 向服务器发送请求        code = r1.status_code #状态码        self.assertEqual(200,code)        print(r1.text) # unicode型文本    def test2(self):        u'''get带参数测试'''        params = {
   'show_env': '1'}        r2 = requests.get(self.url,params=params)        self.assertEqual(200, r2.status_code)    def test3(self):        u'''get带参数、带headers测试'''        params = {
   'show_env': '8'}        headers = {
   'Connection': 'keep-alive', 'Accept-Encoding': 'gzip, deflate',                   'Accept': '*/*','User-Agent': 'python-requests/2.18.3'}        r = requests.get(self.url, params=params,headers=headers)        r3 = r.json()        print(r3)        connect = r3.get('headers').get('Connection')        self.assertEqual('close', connect)  #断言 校验header里的Connection值    def tearDown(self):        passif __name__ == "__main__":    unittest.main()
