php实现抖音开放平台账号授权获取码code、获取access_token

直接上代码

public function index(){
	$code = $_GET['code'];
	$dyClientKey = xxx;
	$dyClientSecret = xxx;
	if(empty($code)){
		$redirect_uri = "http://www.xxx.com";//授权回调域名(要和在抖音平台申请的网站应用回调域名要一致) 用来接收抖音平台返回的code
		$redirect_uri = urlencode($redirect_uri);
		$url = "https://open.douyin.com/platform/oauth/connect/?client_key={$dyClientKey}&response_type=code&scope=user_info,video.create&redirect_uri={$redirect_uri}";
		header("Location:" . $url);
	}else{
		$get_access_token_url = "https://open.douyin.com/oauth/access_token?client_key={$dyClientKey}&client_secret={$dyClientSecret}&grant_type=authorization_code&code={$code}";
		$access_token_info = $this->getJson($get_access_token_url);
        echo '
';
        var_dump($access_token_info);
	}
}
//curl请求
public function getJson($url){
	$ch = curl_init();
	curl_setopt($ch, CURLOPT_URL, $url);
	curl_setopt($ch, CURLOPT_HTTP_VERSION, CURL_HTTP_VERSION_1_0);
	curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
	curl_setopt($ch, CURLOPT_HEADER, FALSE);
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);//为true，则会跟踪爬取重定向页面，否则，不会跟踪重定向页面
	$output = curl_exec($ch);
	curl_close($ch);
	return json_decode($output, true);
}
