account Number:*******

Password:*******

Http://www.rcscloud.cn/common/API

Step 2 : Add account signatures and SMS Templates

Step 3 : Download the template

4th Step: Create a new project in your project gmkcollege.rcscloud and put two files in App_Code into your project, notice that you modify the namespace

5th Step: Front End

<tr class= "Margin-top" > <TD class= "Padding-top text-center" > Mobile phone number </td> <td><input type= "text" class= "inputs" id= "phone" name= "Phone" > </td> <td><input type= "button" value= "Get Verification Code" id= "SMS" onclick= "SendEmail ()" ></td> </tr> <tr> <TD class= "Padding-top text-center" > Verification Code </td> <td><input type= "text" class= "inputs" id= "code" name= "code" ></td> </tr>

Step 6 :js processing

$ (function () { $ ("#sms"). Click (function () { Sendcode ($ ("#sms")); }); v = getcookievalue ("secondsremained");//Get Cookie value if (V > 0) { SetTime ($ ("#sms"));//Start Countdown } }) Send Verification Code function Sendcode (obj) { var PhoneNumber = $ ("#Phone"). Val (); var result = Isphonenum (PhoneNumber); if (result) { Sending a mobile phone using AJAX to the backend text messaging interface $.post ("/college/code", {Phone:phonenumber}, function (data) { if (data = = "OK") { Alert ("Verification code sent successfully!"); } else { Alert ("The verification code sent failed, please resend!"); } }); Addcookie ("secondsremained", 60, 60);//Add cookie record, effective time 60s SetTime (obj); Start the countdown. } } Start the countdown. var countdown; function SetTime (obj) { Countdown = Getcookievalue ("secondsremained"); if (countdown = = 0) { Obj.removeattr ("Disabled"); Obj.val ("Get Verification Code"); Return } else { Obj.attr ("Disabled", true); Obj.val ("Resend (" + Countdown + ")"); countdown--; Editcookie ("secondsremained", Countdown, Countdown + 1); } SetTimeout (function () {settime (obj)}, 1000)//every 1000 milliseconds } Verifying the phone number is legal function Isphonenum (phonenumber) { var Myreg =/^ ((13[0-9]{1}) | ( 15[0-9]{1}) | (18[0-9]{1})) +\D{8}) $/; if (!myreg.test (PhoneNumber)) { Alert (' Please enter a valid mobile number! ‘); return false; } else { return true; } } Add a cookie when sending a verification code function Addcookie (name, value, expireshours) { var cookiestring = name + "=" + escape (value); Determine if the expiration time is set, 0 is invalid when the browser is closed if (expireshours > 0) { var date = new Date (); Date.settime (Date.gettime () + expireshours * 1000); cookiestring = cookiestring + "; expires=" + date.toutcstring (); } Document.cookie = cookiestring; } Modify the value of a cookie function Editcookie (name, value, expireshours) { var cookiestring = name + "=" + escape (value); if (expireshours > 0) { var date = new Date (); Date.settime (Date.gettime () + expireshours * 1000); Unit is milliseconds cookiestring = cookiestring + "; expires=" + date.togmtstring (); } Document.cookie = cookiestring; } Get the value of a cookie by name function Getcookievalue (name) { var strcookie = Document.cookie; var Arrcookie = Strcookie.split (";"); for (var i = 0; i < arrcookie.length; i++) { var arr = arrcookie[i].split ("="); if (arr[0] = = name) { Return unescape (arr[1]); Break } else { Return ""; Break } } }

7th Step: Processing in the background controller

US-san Melt cloud Verification code sent Public ActionResult Validatecode () { String Code = getrandomstring (6); Send Template SMS string result = Rcscloudrestapi.sendtplsms ( "F3b70fc99e1040b99657da1f9411df05", request["Phone"], "@[email protected]=" +code, "" ); To set the verification code to cache var codeinfo = (Object) Code; Cacheopt.setcache ("Code", Codeinfo, Convert.ToInt32 (60)); return Json (Result); } #region generate 6-bit verification code public string getrandomstring (int ilength) { String buffer = "0123456789"; A random character can also be a Chinese character (any) StringBuilder sb = new StringBuilder (); Random r = new Random (); int range = buffer. Length; for (int i = 0; i < ilength; i++) { Sb. Append (buffer. Substring (R.next (range), 1)); } Return SB. ToString (); } #endregion

Step 8 : Cache processing

public class Cacheopt { <summary> Setting up the cache </summary> <param name= "CacheKey" ></param> <param name= "Objobject" ></param> <param name= "Seconds" > Expires after how many seconds </param> public static void Setcache (String CacheKey, Object Objobject, Long Seconds) { System.Web.Caching.Cache Objcache = Httpruntime.cache; Objcache.insert (CacheKey, objobject, NULL, System.DateTime.Now.AddSeconds (Seconds), TimeSpan.Zero); } <summary> Get data cache </summary> <param name= "CacheKey" > Keys </param> public static Object GetCache (String CacheKey) { System.Web.Caching.Cache Objcache = Httpruntime.cache; return Objcache[cachekey]; } }
