    2.7 代理 proxies
        # 无验证
            proxie_dict = {
                "http": "61.172.249.96:80",
                "https": "http://61.185.219.126:3128",
            }
            ret = requests.get("https://www.proxy360.cn/Proxy", proxies=proxie_dict)
            
        
        # 验证代理
            from requests.auth import HTTPProxyAuth
            
            proxyDict = {
                'http': '77.75.105.165',
                'https': '77.75.106.165'
            }
            auth = HTTPProxyAuth('用户名', '密码')
            
            r = requests.get("http://www.google.com",data={'xxx':'ffff'} proxies=proxyDict, auth=auth)
            print(r.text)

    2.8 文件上传 files
        # 发送文件
            file_dict = {
                'f1': open('xxxx.log', 'rb')
            }
            requests.request(

            )
            
    2.9 认证 auth
    
        内部:
            用户名和密码,用户和密码加密,放在请求头中传给后台。
            
                - "用户:密码"
                - base64("用户:密码")
                - "Basic base64("用户|密码")"
                - 请求头:
                    Authorization: "basic base64("用户|密码")"
            
        from requests.auth import HTTPBasicAuth, HTTPDigestAuth

        ret = requests.get('https://api.github.com/user', auth=HTTPBasicAuth('wupeiqi', 'sdfasdfasdf'))
        print(ret.text)
        
    2.10 超时 timeout 
        # ret = requests.get('http://google.com/', timeout=1)
        # print(ret)
    
        # ret = requests.get('http://google.com/', timeout=(5, 1))
        # print(ret)
        
    2.11 允许重定向  allow_redirects
        ret = requests.get('http://127.0.0.1:8000/test/', allow_redirects=False)
        print(ret.text)
        
    2.12 大文件下载 stream
        from contextlib import closing
        with closing(requests.get('http://httpbin.org/get', stream=True)) as r1:
        # 在此处理响应。
        for i in r1.iter_content():
            print(i)
