Linkedin

Question

我正在尝试使用 linkedin API 为请求令牌交换授权码。但是我尝试总是出错：

{ ["error_description"]=> string(107) "missing required parameters, includes an invalid parameter value, parameter more than once. : client_secret" ["error"]=> string(15) "invalid_request" }

我的代码如下：

 public function authorization($authCode)
    {
        //define enviroment and path
        $host = "https://www.linkedin.com/uas/oauth2/accessToken";

        // Generate urlencode data
        $data_string = 'grant_type=authorization_code';
        $data_string .= '&code='.$authCode;
        $data_string .= '&redirect_uri='.redirectUrl;
        $data_string .= '&client_id='.publicKey;
        $data_string .= '&client_secret'.secretKey;
        var_dump($data_string);


        // set up the curl resource
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, $host);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
        curl_setopt($ch, CURLOPT_POST, true);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
        curl_setopt($ch, CURLOPT_HEADER, false);
        curl_setopt($ch, CURLOPT_VERBOSE, true);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
        curl_setopt($ch, CURLOPT_HTTPHEADER, array(
            'Content-Type: application/x-www-form-urlencoded',
        ));

        // execute the request
        $output = curl_exec($ch);

        //echo($output) . PHP_EOL;
        $output = json_decode($output);
        var_dump($output);

        echo $output->access_token;

        // close curl resource to free up system resources
        curl_close($ch);
    }

简单的函数调用如下：

if(!empty($_GET['code']))
{
    $state = $_GET['state'];
    $authCode = $_GET['code'];
    $LinkedIn->authorization($authCode);
}

我尝试通过邮递员使用我的数据发出此请求，并且我成功获得了访问令牌，所以我这里有一些我看不到的错误。

这里有人可以告诉我我做错了什么吗？谢谢

我认为你需要在 client_secret

之后加上一个 'equal to' 符号

$data_string .= '&client_id='.publicKey;
$data_string .= '&client_secret='.secretKey;
var_dump($data_string);
