我如何知道我的访问令牌是否已过期。
我正在使用尝试捕获
try {
$result = file_get_contents('https://www.googleapis.com/calendar/v3/calendars/primary/events?access_token='.$accesstoken);
print_r($result);
}
catch(Exception $e){
echo "Get new token";
}
但它仍然从file_get_contents中得到错误,然后打印"获取新令牌"
如果我想使用卷曲
$ch = curl_init();
curl_setopt($ch,CURLOPT_URL,'https://www.googleapis.com/calendar/v3/calendars/primary/events?access_token='.$accesstoken);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$result = curl_exec($ch);
curl_close($ch);
那么我该怎么做才能发现这里的错误呢?
//if error because access token is invalid,
do here
// my fixed solution
$response= json_decode($result);
if($response->error){ // if result has errors
echo "Get new token";
}
探测此url:
https://www.googleapis.com/oauth2/v1/tokeninfo?access_token={accessToken}
会给你:
{
"audience":<your_client_id>,
"user_id":<user_id_if_userinfo.profile_was_authorized>,
"scope":"<authorized_scope_1> <authorized_scope_1>",
"expires_in":<time_to_live>
}
或错误:
{"error":"invalid_token"}
捕获异常。检查HTTP错误代码是否为401(未经授权)。这意味着您的访问令牌已过期,此时是您刷新访问令牌的时间。
