php实现支付宝授权登录

第一步:

登录到蚂蚁金服开放平台 https://open.alipay.com/platform/home.htm,前提是有商户号。创建应用之后,然后到开发者中心开通对应功能。如图:

 

第二步:

到应用信息里面填写应用网关授权回调地址应用网关填写域名即可,如:www.baidu.com;授权回调地址则需要具体到页面或者方法,如:www.baidu.com/aliLogin.php。

 

 

第三步:

填写接口加签方式。去官方下载签名生成器,然后生成一对秘钥(应用公钥和应用私钥),设置好应用公钥之后,能拿到对应的支付宝公钥。(重点是 应用私钥和支付宝公钥

 

 

第四步:

数据表的设计。可以新建数据表存储支付宝返回数据,也可以在用户表里面新加字段存储。我的实现方法是后者,如图:

下面代码可以看到支付宝返回数据存入对应字段

 

第五步:

下载sdk,地址   https://doc.open.alipay.com/docs/doc.htm?spm=a219a.7629140.0.0.iw1InW&treeId=193&articleId=103419&docType=1 。根据以上步骤拿到的appid,应用私钥(RSA_PRIVATE_KEY)和支付宝公钥(ALIPAY_RSA_PBULIC_KEY),开始调用支付宝接口获取数据。上代码:

/**
     * 支付宝授权登录
     */
    public function aliLogin(){
        //获取配置文件的ali参数
        $ali_config = C("ALI_CONFIG");

        //应用的APPID
        $app_id = "2017061407485473";
        //【成功授权】后的回调地址
        $my_url = "http://".$_SERVER['HTTP_HOST']."/Home/User/aliLogin";

        //Step1:获取auth_code
        $auth_code = $_REQUEST["auth_code"];//存放auth_code
        if(empty($auth_code)){
            //state参数用于防止CSRF攻击,成功授权后回调时会原样带回
            $_SESSION['alipay_state'] = md5(uniqid(rand(), TRUE));
            //拼接请求授权的URL
            $url = "https://openauth.alipay.com/oauth2/publicAppAuthorize.htm?app_id=".$app_id."&scope=auth_user&redirect_uri=".$my_url."&state="
                . $_SESSION['alipay_state'];

            echo("<script> top.location.href='" . $url . "'</script>");
        }
        //Step2: 使用auth_code换取apauth_token
        if($_REQUEST['state'] == $_SESSION['alipay_state'] || 1)
        {
            vendor("Alipay.AopClient"); //引入sdk
            $aop = new \AopClient();
            $aop->gatewayUrl             = "https://openapi.alipay.com/gateway.do";
            $aop->appId                   = $app_id;
            $aop->rsaPrivateKey           = $ali_config['RSA_PRIVATE_KEY'];  //应用私钥
            $aop->alipayrsaPublicKey   = $ali_config['ALIPAY_RSA_PBULIC_KEY'];  //支付宝公钥
            $aop->apiVersion              = '1.0';
            $aop->signType                = 'RSA2';
            $aop->postCharset             = 'utf-8';
            $aop->format                    = 'json';

            //根据返回的auth_code换取access_token
            vendor("Alipay.AlipaySystemOauthTokenRequest");  //调用sdk里面的AlipaySystemOauthTokenRequest类
            $request = new \AlipaySystemOauthTokenRequest();
            $request->setGrantType("authorization_code");
            $request->setCode($auth_code);
            $result = $aop->execute($request);
            $access_token = $result->alipay_system_oauth_token_response->access_token;

        //Step3: 用access_token获取用户信息
            vendor("Alipay.AlipayUserInfoShareRequest");  //调用sdk里面的AlipayUserInfoShareRequest类
            $request = new \AlipayUserInfoShareRequest();
            $result = $aop->execute ( $request, $access_token);
            $responseNode = str_replace(".", "_", $request->getApiMethodName()) . "_response";
            $resultCode = $result->$responseNode->code;
            if(!empty($resultCode)&&$resultCode == 10000){
                $user_data = $result->$responseNode;
                $m = M("Member");
                $data = array();
                $data['sex']              = $user_data->gender=='m'?1:2;
                $data['province']      = $user_data->province;
                $data['city']             = $user_data->city;
                $data['person_name']   = $user_data->nick_name;
                $data['ali_openid']    = $user_data->user_id;
                $data['ali_name']      = $user_data->nick_name;
                $data['ali_img']       = $user_data->avatar;
                $data['addtime']       = date("Y-m-d H:i:s", time());
                $data['person_img']       = $user_data->avatar;
                $data['signtime']       = date("Y-m-d H:i:s", time());

                $user = M("Member")->where(array("ali_openid"=> $user_data->user_id))->find();

    //判断是否是第一次登录
                if($user){
                    $res = M("Member")->where(array("ali_openid"=> $user_data->user_id))->setField("signtime", date("Y-m-d H:i:s", time()));
                    if($res){
                         //成功登录业务逻辑
                       
                    }else{
                        $this->error("操作异常,拒绝访问!", U('user/login'));
                    }
                }else{
                    $res=$m->add($data);
                    if($res){
                         //成功登录业务逻辑


                    }else{
                        $this->error("操作异常,拒绝访问!", U('user/login'));
                    }
                }

            } else {
                $this->error("操作异常,拒绝访问!", U('user/login'));
            }

        }
    }
