京东电商API

大家好~~2016年了~转眼过去三年了...一年没有更新博客了.. ..在上一年里,遇到了几个好哥们,一起写程序一起装逼,以下给大家讲述一下工作上遇到的技术问题,由于这个我開始弄的时候也比較麻烦,不知道从何下手,网上资料除了京东的手冊,其余都没有资料,so~请看

一:首先登录授权获取access_token( 请填好自己的參数 )

'https://auth.360buy.com/oauth/authorize?response_type=code&client_id='.Yii::$app->params['JD_client_id'].'&redirect_uri='.Yii::$app->params['JD_callback'],

控制器(因为时间问题,我就不封装url了)

public function actionCallBack(){

        $url = 'https://auth.360buy.com/oauth/token?grant_type=authorization_code&client_id='.Yii::$app->params['JD_client_id'];
        $url.='&redirect_uri='.Yii::$app->params['JD_callback'].'&code='.Yii::$app->request->get('code').'&client_secret='.Yii::$app->params['JD_app_secret'];

        $result = Common::CURL_GET($url);#这个哪来的呢?事实上就是一个curl操作
        echo '<pre>';
        print_r($result);
        echo '</pre>';
        exit;
    }

Common::GET

 public static function CURL_GET($url)
    {
        $ch = curl_init($url);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
        //https 请求
        if (strlen($url) > 5 && strtolower(substr($url, 0, 5)) == "https") {
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
        }

        $output = curl_exec($ch);
        return $output;
    }

请登录

接下你会接受到返回的access_token,(请保存起来)

然后使用access_token请求接口(  事实上就用到一个curl和一个签名 )

<span style="white-space:pre">	</span> $jd = new JdClient();//这个文件请看下
         $jd->appKey = Yii::$app->params['JD_client_id'];
         $jd->appSecret = Yii::$app->params['JD_app_secret'];
         $jd->accessToken = 'cb0ef5c2-1feb-466a-afe2-ffd5a8294cdd';
         $jd->serverUrl = 'https://api.jd.com/routerjson';
         $jd->method = 'jingdong.dsp.adkcunit.adgroup.get';
         $resp = $jd->execute(['param'=>['id'=>1]], $jd->accessToken);
