PHP解密支付宝小程序的加密数据、手机号的示例代码

1.小程序端代码示例

?

1 2 3 4 5 6 7 8 9 10 11 12 13

my.getPhoneNumber({   success: (res) => {   let encryptedData = res.response;   my.httpRequest({    url: '你的后端服务端' ,    data: encryptedData,   });   },   fail: (res) => {   console.log(res);   console.log( 'getPhoneNumber_fail' );   }, });

2.PHP后端解密示例

public static function decryptData( $encryptedData , $key = '开发设置-接口内容加密方式-查看-字符串' )   {   $encrys = json_decode( $encryptedData , true);   $encryptedData = $encrys [ 'response' ];   $str = base64_decode ( $encryptedData );   $screct_key = base64_decode ( $key );     //设置全0的IV   $iv_size = mcrypt_get_iv_size(MCRYPT_RIJNDAEL_128, MCRYPT_MODE_CBC);   $iv = str_repeat ( "\0" , $iv_size );     $decrypt_str = mcrypt_decrypt(MCRYPT_RIJNDAEL_128, $screct_key , $str , MCRYPT_MODE_CBC, $iv );   $decrypt_str = self::stripPKSC7Padding( $decrypt_str );   return $decrypt_str ;   }     public static function stripPKSC7Padding( $source )   {   $char = substr ( $source , -1);   $num = ord( $char );   if ( $num == 62) return $source ;   $source = substr ( $source , 0, - $num );   return $source ;   }

3.解密返回
