我正在尝试在Linkedin上自动托管，并遵循本教程：http://www.tricksofit.com/2015/09/get-user-access-token-for-linkedin#.Vy13KYR97IU
我得到这个错误：
致命错误：在第23行调用C:''xammp''examp''htdocs''linkedin''one''callback.php中未定义的函数http（）
请有人帮我解决它。
require_once("OAuth.php");
$data = array(
'consumer_key' => 'xxxxxxxxxxxxx',
'consumer_secret' => 'xxxxxxxxxxx',
'callback_url' => 'http://localhost/linkedin/one/callback.php'
);
if(isset($_REQUEST['oauth_verifier'])){
$data['oauth_token'] = $_SESSION['oauth_request_token'];
$data['oauth_token_secret'] = $_SESSION['oauth_request_token_secret'];
$method = new OAuthSignatureMethod_HMAC_SHA1();
$consumer = new OAuthConsumer($data['consumer_key'], $data['consumer_secret']);
$token = new OAuthConsumer($data['oauth_token'],$data['oauth_token_secret']);
$args = array();
$request = OAuthRequest::from_consumer_and_token($consumer, $token, 'GET', "https://api.linkedin.com/uas/oauth/accessToken", $args);
$request->set_parameter("oauth_verifier", $_REQUEST['oauth_verifier']);
$request->sign_request($method, $consumer, $token);
$request = http($request->to_url(),false);
function http($url, $post_data = null) {
$ch = curl_init();
if(defined("CURL_CA_BUNDLE_PATH"))
curl_setopt($ch, CURLOPT_CAINFO, CURL_CA_BUNDLE_PATH);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
if(isset($post_data))
{
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_data);
}
$response = curl_exec($ch);
curl_close($ch);
return $response;
}
parse_str($request, $token);
$tokens = new OAuthConsumer($token['oauth_token'], $token['oauth_token_secret'], 1);
$access_token = serialize($tokens);
}
当您在另一个函数中定义一个函数时，就会发生undefined function错误。
function foo() {
$request = http();
echo $request;
function http() {
return "aaa";
}
}
foo();
您需要在当前功能范围之外定义http()：
function foo(){
$request = http();
echo $request;
}
function http() {
return "aaa";
}
foo();
