Java implementation to send SMS verification verification code function

These days, the boss let me get a message verification code to send the function, the use of the letter easy access to the SMS platform interface, and then in Java using httpclient analog POST request or GET request (see the message platform requirements, the general situation is a POST request), Invoke the interface provided by the SMS platform (Follow the interface specification of the SMS platform). See the code specifically:

When using httpclient, you need to introduce it in your project:

Commons-httpclient-3.1.jar

This jar package,

Project structure:

1. Create an HTTP impersonation Request tool class, then write a post method or Get method

2, in the creation of a class, generate verification code, and then pass the corresponding parameters (different SMS platform interface will have different parameter requirements, the general text message platform provided by the interface document will be available, directly read the document and then as required)

          Public StaticStringCreaterandomvcode(){//Verification CodeString Vcode =""; for(inti =0; I <6; i++) {Vcode = Vcode + (int) (Math.random () *9); }returnVcode; }/** * Test * Method Description * @Discription: Extension description * @param args * @return void * @Author: Feizi * @Date: April 17, 2015 PM 7:26:36 * @ModifyUser: Feizi *

          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 in doubt please consult 400-069-2886 (Customer service telephone)" XXX Center ")); }}

Then execute, the general situation of the parameter is passed correctly, according to the specification of the interface document to operate, will send a successful, mobile phone can receive the verification code, and then may appear the problem is: Send the text message content may appear in Chinese garbled, and then will send unsuccessful, According to the requirements of the SMS platform for the corresponding code can be. It is usually UTF-8 encoded.
