写个页面检查阿里云的账号存在与否
之前无聊写了个阿里云账号注册的页面，主要是检查账号是否存在，现在分享下：
主要通过webrequest实现：
1. 写个阿里云邮箱类：
using System;using System.Collections.Generic;using System.Web;/// <summary>/// Summary description for AliEmal/// </summary>public class AliEmail{ public ContentClass content; public bool hasError;}public class ContentClass{ public string message; public int status; public bool success;}
2. 写个邮箱验证类：
using System;using System.Collections.Generic;using System.Net;using System.Net.Mail;using System.Text;using System.Text.RegularExpressions;using System.Web;/// <summary>/// Summary description for Util/// </summary>public class AliUtil{ public AliUtil() { } // // TODO: Add constructor logic here // #region 验证邮箱验证邮箱 /**/ /// <summary> /// 验证邮箱 /// </summary> /// <param name="source"></param> /// <returns></returns> public static bool IsEmail(string source) { return Regex.IsMatch(source, @"^\w+([-+.']\w+)*@\w+([-.]\w+)*\.\w+([-.]\w+)*$", RegexOptions.IgnoreCase);

3. 写个简单的前台验证页面：
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="AliCheck.aspx.cs" Inherits="AliCheck" %><!DOCTYPE html><html xmlns="http://www.w3.org/1999/xhtml"><head runat="server"> <title></title></head><body> <form id="form1" runat="server"> <div> <div> 阿里云邮箱： <asp:TextBox ID="AliEmailName" runat="server"></asp:TextBox> <asp:Button ID="Check" runat="server" Text="检查是否存在" OnClick="Check_Click" /> <div style="color:red;" id="showError" runat="server"></div> </div> </div> </form></body></html>
4.写个验证页面后台：
using System;using System.Collections.Generic;using System.IO;using System.Net;using System.Text;using System.Threading;using System.Web;using System.Web.UI;using System.Web.UI.WebControls;public partial class AliCheck : System.Web.UI.Page{ public T Deserializer<T>(string jsonString) { T item = default(T); item = Newtonsoft.Json.JsonConvert.DeserializeObject<T>(jsonString); return item; } protected void Page_Load(object sender, EventArgs e) { } public string CheckTest(string email) { string responseBody = string.Empty; string serverUri = string.Format("https://passport.alipay.com/register/emailRpc/checkEmail.json"); string requestBody = string.Format("email={0}&fromSite=6&_csrf_token=TB2pedPPWRa0ly94qNozE5", email.Replace("@","%40")); ////set limit for supporting 200 connection ServicePointManager.DefaultConnectionLimit = 200; HttpWebRequest request = (HttpWebRequest)WebRequest.Create(serverUri); ////extend timeout for decrease request timeout re-trying times request.Timeout = 60 * 1000; request.Method = @"PUT"; request.ContentType = "application/x-www-form-urlencoded; charset=UTF-8"; UTF8Encoding encoding = new UTF8Encoding(); byte[] data = encoding.GetBytes(requestBody); request.ContentLength = data.Length; request.KeepAlive = true; request.Accept = "application/json, text/javascript, */*; q=0.01"; request.Headers.Set("Cache-Control", @"no-cache"); request.Referer = "https://passport.alipay.com/register/register.htm?fromSite=6¶ms=%7B%22site%22%3A%226%22%2C%22ru%22%3A%22http%3A%2F%2Fbuy.aliyun.com%2F%22%7D"; request.UserAgent = "Mozilla/5.0 (compatible; MSIE 10.0; Windows NT 6.2; WOW64; Trident/6.0)"; request.Headers.Set("Cookie", @"_umdata=5A25312D486F1DD6724ACD835355F6D7578488DB731A9A20CC7F64E6E8EE8F56B5D2A44298446384A482322D8118098ECAEDCEACF887A1CD93603238261471E839CB6075F6DCEA1B; cna=hOp6DPkMlF4CAafc6OGg639S; ALIPAYJSESSIONID=RZ02mGHIM9XnmVgsHI8rD5gmaLXOfkauthRZ02; ctoken=1bt0CRyVd15nSnCX0RHEAI2T7PsExY; umt=HB7279bc2f80e20b02ad3c6a4f6d573692; ac-stat=no; JSESSIONID=PO966Z91-R05SQP6XK00KCQCZTNYY1-AXMUZ1ZH-RVPO1; _ufaon_=6; ALI_USER_REGISTER_TOKEN=b37b07d33b6de91b787781a6d32c844c; tmp0=eNrz4A12DQ729PeL9%2FV3cfUxiK7OTLFSCvC3NDOLsjTUDTIwDQ4MMIvwNjDwdg50jgrxi4w01HWM8A2NMozy0A0KC%2FA3VNJJLrEyNDGwMLG0sDA1NjW00ElMRhPIrbAyqI0CAGg3HQg%3D"); bool isSent = false; int retryCount = 0; string errorStr = string.Empty; while (!isSent && retryCount <= 100) { retryCount++; try { using (Stream newStream = request.GetRequestStream()) { newStream.Write(data, 0, data.Length); } isSent = true; } catch (Exception exc) { if (!errorStr.Contains(exc.ToString())) { errorStr += exc.ToString(); } ////Re-try when operation timeout if (!exc.ToString().Contains("The operation has timed out")) { LogError(exc.ToString()); } Thread.Sleep(1000); } } if (retryCount > 100) { string err = string.Format("request.GetRequestStream try 100 times and timeout! detail error: {0}", errorStr); LogError(err); return err; } HttpWebResponse response = (HttpWebResponse)request.GetResponse(); using (StreamReader stream = new StreamReader(response.GetResponseStream(), Encoding.UTF8)) { responseBody = stream.ReadToEnd(); } ////need to close or abort request for each call to fix timeout issue, otherwise it will fail when the 3rd call! if (request != null) { request.Abort(); } if (response.StatusCode != HttpStatusCode.OK) { string err=string.Format("Failed, error:{1}", response.ToString()); LogError(err); return err; } if (response != null) { response.Close(); } return responseBody; } public void LogError(string content) { File.AppendAllText("log.log","ERROR: "+content + Environment.NewLine); } protected void Check_Click(object sender, EventArgs e) { if (!AliUtil.IsEmail(AliEmailName.Text.Trim())) { showError.InnerHtml = "邮箱不合法！"; return; } AliEmail email = Deserializer<AliEmail>(CheckTest(AliEmailName.Text.Trim())); if (email.hasError == false && email.content.success == true) { showError.InnerHtml = "恭喜您！可以注册！"; } else { showError.InnerHtml=email.content.message; } //showError.InnerHtml = CheckTest(AliEmailName.Text.Trim()); }}
