Regular expression for verifying mobile phone number

---

First first need to register a third-party site, I recommend a site mutually million wireless , after registering each user can send 50 SMS free.

Let's take the C# implementation of mobile phone sending verification code as an example. The basic idea is to generate a 4-digit random number locally, then splice it into a string with the local user name + password + random number, convert it into binary data, and send it to the website of "Muyi Wireless" in the form of a network stream , The next job website will do it for you.

Specific implementation-encapsulate a class, U layer directly call

public class Phone
{
     public static string PostUrl = ConfigurationManager.AppSettings["WebReference.Service.PostUrl"];//写在了配置文件中
     /// <summary>
     /// 实现发送验证码
     /// </summary>
     /// <param name="phoneno">手机号</param>
     /// <returns>验证码</returns>
     public static  int PhoneNo(string phoneno)
     {
         string account = "******";//登录“互亿无线网站”查看用户名 登录用户中心->验证码通知短信>产品总览->API接口信息->APIID
         string password = "*******"; //登录“互亿无线网站”查看密码 登录用户中心->验证码通知短信>产品总览->API接口信息->APIKEY
         string mobile = phoneno;
         //string mobile = Request.QueryString["mobile"];
         Random rad = new Random();
         int mobile_code = rad.Next(1000, 10000);   //生成随机数
         //textBox3.Text = mobile_code.ToString();返回值
         string content = "您的验证码是：" + mobile_code + " 。请不要把验证码泄露给其他人。";



         string postStrTpl = "account={0}&password={1}&mobile={2}&content={3}";  //用户名+密码+注册的手机号+验证码

         UTF8Encoding encoding = new UTF8Encoding();  //万国码
         byte[] postData = encoding.GetBytes(string.Format(postStrTpl, account, password, mobile, content)); //将字符串postStrTpl中的格式项替换为四个个指定的 Object 实例的值的文本等效项。再转为二进制数据

         HttpWebRequest myRequest = (HttpWebRequest)WebRequest.Create(PostUrl);//对统一资源标识符 (URI) 发出请求。 这是一个 abstract 类。
         myRequest.Method = "POST";
         myRequest.ContentType = "application/x-www-form-urlencoded";
         myRequest.ContentLength = postData.Length;

         Stream newStream = myRequest.GetRequestStream(); //
         // Send the data.
         newStream.Write(postData, 0, postData.Length);
         newStream.Flush();
         newStream.Close();

         HttpWebResponse myResponse = (HttpWebResponse)myRequest.GetResponse();
         if (myResponse.StatusCode == HttpStatusCode.OK)
         {
             StreamReader reader = new StreamReader(myResponse.GetResponseStream(), Encoding.UTF8);

             //code状态返回值；msg查询结果描述
             string res = reader.ReadToEnd();
             int len1 = res.IndexOf("</code>");
             int len2 = res.IndexOf("<code>");
             string code = res.Substring((len2 + 6), (len1 - len2 - 6));

             int len3 = res.IndexOf("</msg>");
             int len4 = res.IndexOf("<msg>");
             string msg = res.Substring((len4 + 5), (len3 - len4 - 5));
             //MessageBox.Show(msg);
             return mobile_code;
         }
         else
         {
             return 0;
             //访问失败
         }
     }
       
 }

The content of the configuration file is as follows

<appSettings>
	<!--发送验证码的接口-->
	<add key="WebReference.Service.PostUrl" value="http://106.ihuyi.cn/webservice/sms.php?method=Submit"/>
	<add key="WebReference.sms" value="http://106.ihuyi.cn/webservice/sms.php?smsService"/>

Regular expression for verifying mobile phone number

/// <summary>
/// 验证手机号的正则表达式
/// </summary>
/// <param name="phoneid">手机号</param>
/// <returns>bool值</returns>
public static bool VailPhoneCode(string phoneid)
{
       string str = @"^1[3-9]\d{9}$";  
       Regex regex = new Regex(str);//正则表达式类
       if (regex.IsMatch(phoneid))//Regex验证
       {
            return true;
       }
       else
       {
            return false;
       }
}

I have other languages ​​here to implement the source code of the verification code sent by the mobile phone. You can send me private messages. Send it to you privately.
