企业微信支付 发红包和给员工付款功能

前提：​

企业微信官方提供的SDK中并没有企业微信支付这块的代码。

我的环境​

我是用lumen框架进行开发的， 整个系统是用模块化的思想开发的。

介绍​

1. 修改官方SDK代码​

官方的SDK里面有一些错误的地方，比如静态方法里面用了$this 这些都要自己使用的时候去改过来。

我们用要改的地方是

文件 wework\app\SDK\weworkapi\api\src\CorpAPI.class.php

    static private function _HttpPostXml($url, $args)
    {
        $postData = Utils::Array2Xml("xml", $args);
        $rspRawStr = HttpUtils::postXmlCurl( $postData,$url,true);
        return Utils::Xml2Array($rspRawStr);
    }

文件 \wework\app\SDK\weworkapi\utils\HttpUtils.class.php

    /**
     * 以post方式提交xml到对应的接口url
     *
     * @param WxPayConfigInterface $config  配置对象
     * @param string $xml  需要post的xml数据
     * @param string $url  url
     * @param bool $useCert 是否需要证书，默认不需要
     * @param int $second   url执行超时时间，默认30s
     * @throws WxPayException
     */
    public static function postXmlCurl( $xml, $url, $useCert = false, $second = 30)
    {
        $ch = curl_init();
        $curlVersion = curl_version();
        $ua = "WXPaySDK/3 (".PHP_OS.") PHP/".PHP_VERSION." CURL/".$curlVersion['version']." ".'1508124981';

        //设置超时
        curl_setopt($ch, CURLOPT_TIMEOUT, $second);


        curl_setopt($ch,CURLOPT_URL, $url);
        curl_setopt($ch,CURLOPT_SSL_VERIFYPEER,TRUE);
        curl_setopt($ch,CURLOPT_SSL_VERIFYHOST,2);//严格校验s
        curl_setopt($ch,CURLOPT_USERAGENT, $ua);
        //设置header
        curl_setopt($ch, CURLOPT_HEADER, FALSE);
        //要求结果为字符串且输出到屏幕上
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);

        if($useCert == true){
            //设置证书
            //使用证书：cert 与 key 分别属于两个.pem文件
            //证书文件请放入服务器的非web目录下
            $sslCertPath = storage_path('cert'.DIRECTORY_SEPARATOR.'apiclient_cert.pem');
            $sslKeyPath = storage_path('cert'.DIRECTORY_SEPARATOR.'apiclient_key.pem');
//            dump($sslCertPath);
//            dump($sslKeyPath);
            curl_setopt($ch,CURLOPT_SSLCERTTYPE,'PEM');
            curl_setopt($ch,CURLOPT_SSLCERT, $sslCertPath);
            curl_setopt($ch,CURLOPT_SSLKEYTYPE,'PEM');
            curl_setopt($ch,CURLOPT_SSLKEY, $sslKeyPath);
        }
        //post提交方式
        curl_setopt($ch, CURLOPT_POST, TRUE);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $xml);
        //运行curl
        $data = curl_exec($ch);

        //返回结果
        if($data){
            curl_close($ch);
            return $data;
        } else {
            $error = curl_errno($ch);
            curl_close($ch);
            throw new WxPayException("curl出错，错误码:$error");
        }


    }

2. 配置类 trait类​

这是我的一个配置的trait类，这些写的好处是，可以在每个模块的Controller类中，使用构造函数初始化。 模块的各个类里面使用这些参数，

namespace App\Traits;

trait WorkConfig
{
    protected $api;
    protected $corpid;
    protected $appid;
    protected $agentid;
    protected $redirect_uri;
    protected $token;
    protected $encodingAESKey;
    protected $key;
}

下面是我封装的发红包和给员工付款功能代码。

签名的步骤太复杂，不去自己写的话，不知道会有这么多坑。 关键是官方的文档里写的还挺清楚，怪我没认真看。
好了。我用2天完成的，不知道你们会花费多久时间完成。
