wxxcx

Laravel 5 WeChat applet extension

The official encryption and decryption SDK of the mini program is already very clear, but it has been changed to Laravel style, which is just like a bricklayer. As for reinventing the wheel, I found that other people's extensions had code errors when decrypting user information, and there was no mention of the need to install a Laravel Curl extension. I had to write a 0.0 myself based on their source code, without relying on other extensions, just install and use it directly.

Mini program API interface

• User login: wx.login
• Get user information: wx.getUserInfo

Install

The encryption function mcrypt_module_open() of PHP7.1 has been abandoned due to obsolescence. People using PHP7.1 version please install version 2.0 code

Execute the following command to install the latest stable version:

PHP < 7.1

composer require iwanli/wxxcx=1. *

PHP > 7.1

composer require iwanli/wxxcx=2. *

Or add the following information to your composer.json file:

PHP < 7.1

 "iwanli/wxxcx" : " ^1.0 "

PHP > 7.1

 " iwanli/wxxcx " : " ^2.0 "

Then register the service provider to the specific location in Laravel: providers array in /config/app.php :

 Iwanli  Wxxcx WxxcxServiceProvider::class,

Publish configuration file:

php artisan vendor:publish --tag=wxxcx

After the command is completed, a wxxcx.php configuration file will be added to your configuration folder such as: /config/wxxcx.php .

After generating the configuration file, fill in AppID and AppSecret of the mini program into the /config/wxxcx.php file

Use in Laravel 5 controller (example)

 . . .

use Iwanli  Wxxcx  Wxxcx ;

class WxxcxController extends Controller
{
    protected $ wxxcx ;

    function __construct ( Wxxcx $ wxxcx )
    {
        $ this -> wxxcx = $ wxxcx ;
    }

     */
    public function getWxUserInfo ()
    {
        //code 在小程序端使用 wx.login 获取
        $ code = request ( ' code ' , '' );
        //encryptedData 和 iv 在小程序端使用 wx.getUserInfo 获取
        $ encryptedData = request ( ' encryptedData ' , '' );
        $ iv = request ( ' iv ' , '' );

        //根据 code 获取用户 session_key 等信息, 返回用户openid 和 session_key
        $ userInfo = $ this -> wxxcx -> getLoginInfo ( $ code );

        //获取解密后的用户信息
        return $ this -> wxxcx -> getUserInfo ( $ encryptedData , $ iv );
    }
}

User information return format:

 {
    "openId": "xxxx",
    "nickName": "晚黎",
    "gender": 1,
    "language": "zh_CN",
    "city": "",
    "province": "Shanghai",
    "country": "CN",
    "avatarUrl": "http://wx.qlogo.cn/mmopen/xxxx",
    "watermark": {
        "timestamp": 1495867603,
        "appid": "your appid"
    }
}

The applet obtains code, iv, and encryptedData and sends a request to the server. Sample code:

 //调用登录接口
wx . login ( {
    success : function ( response ) {
        var code = response . code
        wx . getUserInfo ( {
            success : function ( resp ) {
                wx . request ( {
                    url : 'your domain' ,
                    data : {
                        code : code ,
                        iv : resp . iv ,
                        encryptedData : resp . encryptedData
                    } ,
                    success : function ( res ) {
                        console . log ( res . data )
                    }
                } )
            }
        } )
    } ,
    fail : function ( ) {
        ...
    }
} )
