抖音小程 服务端OpenAPI 开发示例

开发流程如下图

为方便开发 我用的是沙盒模式

开放平台前三个接口开发流程如下，我的代码没做相关优化

代码如下

1、 接口调用凭证

 //接口调用凭证
    public function getAccessToken()
    {
        $uri = 'https://open-sandbox.douyin.com/api/apps/v2/token';
        $options = [
            'body' => json_encode([
                'appid' => 'tt5d842b39c2bb31',
                'secret' => '9208a4e3130eb24cf9fcbc4a4906765c1',
                'grant_type' => 'client_credential']),
            'headers' => [
                'Content-Type' => 'application/json'
            ]
        ];
        $response = (new \GuzzleHttp\Client)->post($uri, $options);
        $body = $response->getBody();
        $stringBody = (string)$body;
        $result = json_decode($stringBody, true);
        if ($result['err_no'] == 0) {
            return $result['data']['access_token'];
        }
        return null;
    }

2、登录 （通过小程序login接口获取到登录凭证后，开发者可以通过服务器发送请求的方式获取 session_key 和 openId）。

//通过小程序login接口获取到登录凭证后，开发者可以通过服务器发送请求的方式获取 session_key 和 openId。
    public function code2Session()
    {
        $uri = 'https://open-sandbox.douyin.com/api/apps/v2/jscode2session';
        //客户端获取并传过来
        $code = 'T9loKB1gsyl92x5s7wiTwKteJgeA5Pjq21JNWPtXfx1BUXz0PIzl2ruw2fnPjc9VDA97LlXkKvQW6qTM-0jUNN-frfnVZ5nBluYdVos3FJw8mGe0iaHJHkXq7i4';
        $options = [
            'body' => json_encode([
                'appid' => 'tt5d842b39c2b6',
                'secret' => '9208a4e3130eb2408fcf9fcbc4a496',
                'code' => $code]),
            'headers' => [
                'Content-Type' => 'application/json'
            ]
        ];
        $response = (new \GuzzleHttp\Client)->post($uri, $options);
        $body = $response->getBody();
        $stringBody = (string)$body;
        $result = json_decode($stringBody, true);
        if ($result['err_no'] == 0) {
            return $result['data'];
        }
        return ['openid' => '_000DO0RDLCqmW1_EcB4GXidO-bl8T', 'session_key' => ''];
    }

3、数据缓存

//数据缓存
public function setUserstorage()
    {
        $user = $this->code2Session();
        $body = [
            'kv_list' => [
                ['key' => 'name', 'value' => 'yang']
            ]
        ];
        //用户登录态签名
        $signature = hash_hmac('sha256', json_encode($body), $user['session_key']);
        $uri = 'https://open-sandbox.douyin.com/api/apps/set_user_storage';
        $response = (new \GuzzleHttp\Client)->post($uri, [
            'query' => [
                'access_token' => $this->getAccessToken(),
                'openid' => $user['openid'],
                'signature' => $signature,
                'sig_method' => 'hmac_sha256',
            ],
            'body' => json_encode($body),
            'headers' => [
                'Content-Type' => 'application/json'
            ]
        ]);
        $body = $response->getBody();
        $stringBody = (string)$body;
        $result = json_decode($stringBody, true);
        dd($result);
    }
