CodeIgniter development of the method of implementing Alipay Interface Call Example _php instance

This paper illustrates the method of CodeIgniter development to realize the call of Alipay interface. Share to everyone for your reference, specific as follows:

Get ready:

1, Alipay official Download the latest Interface class library
2, after decompression, the directory, "Instant to account Transaction interface-create_direct_pay_by_user\demo\create_direct_pay_by_user-php-utf-8\lib" Copy to application\ Third_party directory, and renamed Lib as Alipay
3, the same copy Cacert.pem file to the "Application\third_party\alipay" directory, this is not necessary, in the SSL channel to use the certificate

Code instance:

The following list only controller part of the code, view and model according to their actual needs to write

<?php if (! defined (' BasePath ')) exit (' No Direct script access allowed ');
  /** * alipy Payment interface * @author onwulc@163.com * * */class Alipay extends Ci_controller {private $alipay _config;
