调用/ v2 / me时出现“资源我不存在” API错误

Question

当我尝试调用URL GET：/ v2 / me时，收到错误消息“资源不存在”。

获取：https://api.linkedin.com/v2/me?projection=(id,firstName,lastName,profilePicture)

收到来自https://www.linkedin.com/oauth/v2/accessToken

的令牌

授权网址：

$url = 'https://www.linkedin.com/oauth/v2/authorization'
        .'?response_type=code'
        .'&client_id='."77uuvjhz11mi71"
        .'&redirect_uri='."http://localhost/linkedin"
        .'&state=123123123'
        .'&scope=r_liteprofile%20r_emailaddress%20w_member_social';

请求：

...
$linkedin->getAccessToken($_GET['code']);
...
$this->setMethod("GET");
$this->setUrl("https://api.linkedin.com/v2/me?projection=(id,firstName,lastName,profilePicture)");
$this->setHeaders([
    "Authorization: Bearer ".$this->accessToken,
]);
$resp = $this->sendRequest();

响应：

  +"status": 404
