Java implements the SMS Verification Code sending Function

Java implements the SMS Verification Code sending Function

In the past few days, the boss asked me to GET a function to send text message verification codes, using the SMS platform interface of Xinyi, and then using HttpClient in Java to simulate POST or GET requests (see the requirements of the SMS platform, generally, POST requests are used to call the interfaces provided by the SMS platform (follow the API specifications of the SMS platform ). Specific Code:

When using HttpClient, you must introduce:

Commons-httpclient-3.1.jar

This jar package,

Project Structure:

1. Create an Http simulated request tool class, and then write a POST method or GET method. <喎?http: www.bkjia.com kf ware vc " target="_blank" class="keylink"> VcD4NCjxwcmUgY2xhc3M9 "brush: java;"> /*** File Description * @ Description: Extension Description * @ Copyright: 2015 dreamtech.com.cn Inc. all right reserved * @ Version: V6.0 */package com. demo. util; import java. io.

2. Create a class, generate a verification code, and then pass the corresponding parameters (different SMS platform interfaces have different parameter requirements. This is generally available in the interface documentation provided by the SMS platform, directly read the document and follow the instructions)

/*** File Description * @ Description: Extension Description * @ Copyright: 2015 dreamtech.com.cn Inc. all right reserved * @ Version: V6.0 */package com. demo. util; import java.net. URLEncoder; import java. util. hashMap; import java. util. map;/*** @ Author: feizi * @ Date: 9:24:48, January 1, April 17, 2015 * @ ModifyUser: feizi * @ ModifyDate: 9:24:48, January 1, April 17, 2015 * @ Version: v6.0 */public class SendMsgUtil {/*** Method for sending SMS messages * @ Discription: extension Description * @ param phones * @ param content * @ return String * @ Author: feizi * @ Date: 7:18:08, January 1, April 17, 2015 * @ ModifyUser: feizi * @ ModifyDate: april 17, 2015 7:18:08 */@ SuppressWarnings (deprecation) public static String sendMsg (String phones, String content) {// SMS interface URL submission address String url = SMS interface URL submission address; Map
  
   
Params = new HashMap
   
    
(); Params. put (zh, user account); params. put (mm, user password); params. put (dxlbid, SMS category number); params. put (extno, extended number); // mobile phone number. Multiple numbers are separated by commas. put (hm, phones); // URLEncoder the text message to encode params. put (nr, URLEncoder. encode (content); return HttpRequestUtil. getRequest (url, params);}/*** randomly generated 6-digit random Verification Code * method Description * @ Discription: Extension Description * @ return String * @ Author: feizi * @ Date: April 17, 2015 7:19:02 * @ ModifyUser: feizi * @ ModifyDate: April 17, 2015 7:19:02 */public static String createRandomVcode () {// verification code String vcode =; for (int I = 0; I <6; I ++) {vcode = vcode + (int) (Math. random () * 9);} return vcode;}/*** test * method Description * @ Discription: Extension Description * @ param args * @ return void * @ Author: feizi * @ Date: April 17, 2015 7:26:36 * @ ModifyUser: feizi * @ ModifyDate: April 17, 2015 7:26:36 */public static void main (String [] args) {// System. out. println (SendMsgUtil. createRandomVcode (); // System. out. println (& ecb = 12. substring (1); System. out. println (sendMsg (18123456789,15123456789, dear user, your verification code is + SendMsgUtil. createRandomVcode () +, valid for 60 seconds. If you have any concerns, please contact 400-069-2886 (Customer Service Hotline) [XXX center ]));}}
   
  

Then execute the following command. Generally, if the parameter is correctly transmitted and the operation is performed according to the specifications in the interface documentation, the verification code will be sent successfully, and the mobile phone will receive the verification code. Then the possible problem is: the text message may contain garbled Chinese characters, and cannot be sent successfully. encode the text message according to the requirements of the SMS platform. Generally, it is a UTF-8 code.
