如何使用php curl获取有效的fb access_token？

Question

我正在研究一个需要使用curl的用户访问令牌的项目。 用户将输入他的用户名和密码。他将使用curl登录Facebook。登录部分起作用。我还得到一个令牌，其中包含管道：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;

为什么使用卷曲？你不能使用PHPSDK？它更容易...

但我想你错过了pase权限参数。

Answer 2

的SDK PHP库（你可以找到一个更新版本here）使用卷曲了。我们是否有机会重新发明轮子？
