Question

我正在开发一个项目，该项目需要使用curl的用户访问令牌。用户将输入他的用户名和密码。他将使用curl登录到facebook。登录部分有效。我还获得了一个令牌，其中包含pipline，如：xxxxxxx | xxxxxxxxxxxxxxxxx，但我想要一个访问令牌发布到登录用户墙。

我使用的代码是：

// your facebook credentials
$username = "xxxxxxxxxxxxxxxx";
$password = "xxxxxxxx";

// access to facebook home page (to get the cookies)
$curl = curl_init ();
curl_setopt ( $curl, CURLOPT_URL, "http://www.facebook.com" );
curl_setopt ( $curl, CURLOPT_FOLLOWLOCATION, 1 );
curl_setopt ( $curl, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $curl, CURLOPT_ENCODING, "" );
curl_setopt ( $curl, CURLOPT_COOKIEJAR, getcwd () . '/cookies_facebook.cookie' );
curl_setopt ( $curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)" );
$curlData = curl_exec ( $curl );
curl_close ( $curl );

// do get some parameters for login to facebook
$charsetTest = substr ( $curlData, strpos ( $curlData, "name=\"charset_test\"" ) );
$charsetTest = substr ( $charsetTest, strpos ( $charsetTest, "value=" ) + 7 );
$charsetTest = substr ( $charsetTest, 0, strpos ( $charsetTest, "\"" ) );

$locale = substr ( $curlData, strpos ( $curlData, "name=\"locale\"" ) );
$locale = substr ( $locale, strpos ( $locale, "value=" ) + 7 );
$locale = substr ( $locale, 0, strpos ( $locale, "\"" ) );

$lsd = substr ( $curlData, strpos ( $curlData, "name=\"locale\"" ) );
$lsd = substr ( $lsd, strpos ( $lsd, "value=" ) + 7 );
$lsd = substr ( $lsd, 0, strpos ( $lsd, "\"" ) );

// do login to facebook
$curl = curl_init ();
curl_setopt ( $curl, CURLOPT_URL, "https://login.facebook.com/login.php?login_attempt=1" );
curl_setopt ( $curl, CURLOPT_FOLLOWLOCATION, 1 );
curl_setopt ( $curl, CURLOPT_RETURNTRANSFER, 1 );
curl_setopt ( $curl, CURLOPT_POST, 1 );
curl_setopt ( $curl, CURLOPT_SSL_VERIFYPEER, false );
curl_setopt ( $curl, CURLOPT_POSTFIELDS, "charset_test=" . $charsetTest . "&locale=" . $locale . "&non_com_login=&email=" . $username . "&pass=" . $password . "&charset_test=" . $charsetTest . "&lsd=" . $lsd );
curl_setopt ( $curl, CURLOPT_ENCODING, "" );
curl_setopt ( $curl, CURLOPT_COOKIEFILE, getcwd () . '/cookies_facebook.cookie' );
curl_setopt ( $curl, CURLOPT_COOKIEJAR, getcwd () . '/cookies_facebook.cookie' );
curl_setopt ( $curl, CURLOPT_USERAGENT, "Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9.2) Gecko/20100115 Firefox/3.6 (.NET CLR 3.5.30729)" );



$url = "https://graph.facebook.com/oauth/access_token";
$postString = "client_id=XXXXXXXX&client_secret=XXXXXXXXXXXXXXX&type=client_cred";

curl_setopt($curl, CURLOPT_URL, $url);
curl_setopt($curl, CURLOPT_FAILONERROR, 1);
curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($curl, CURLOPT_POST, 1);
curl_setopt($curl, CURLOPT_POSTFIELDS, $postString);
$access_token = str_replace( "access_token=", "", curl_exec($curl) );

echo $access_token;

Answer 1

为什么要使用卷曲？你不能使用PHP SDK？这更容易......

但我觉得你错过了pase权限参数。

Answer 2

SDK PHP库（您可以找到更新版本here）也使用cURL。我们是否有机会重新发明轮子？

如何使用php curl获取有效的fb access_token？
