为什么我的Facebook Connect按钮带我错误的网址？ [英] Why is my Facebook Connect button taking me to the wrong URL?

问题描述

如果我在PHP SDK中调用名为getLoginUrl（）的方法，它将返回正确的登录URL。此URL包含多个参数，其中一个是我的API密钥，它是正确的。这是我的连接按钮应该带我的URL。

但是，当我实际点击我的网站上的连接按钮时，会弹出一个弹出窗口，并说无效API密钥指定。有一点检查，我看到这个弹出窗口中的URL表示api_key = undefined。实际上，该URL与登录URL应该是完全不同的。

任何想法为什么会发生这种情况？
只有冲突我可以想象是codeigniter或jQuery。

很难更具体。我猜想这将需要很好的了解Facebook SDK的答案。

非常感谢。 ：）

解决方案

如果需要，PHP应该只处理登录回调，应该通过javascript完成登录。

FB api初始化：

 < div id =fb-root>< / DIV> 
< script src =http://connect.facebook.net/en_US/all.js>< / script> 
< script> 
 FB.init（{
 appId：appId，
 status：true，
 cookie：true，
 xfbml：true 
}）; 
< / script> 
  

然后可以在某些按钮上触发fb登录对话框：

  FB.login（function（response）{
 // callback 
}，{perms：'publish_stream'}）; 
  

还要确保您的fb应用程序在连接选项卡下有正确的设置 - 连接网址和基本域应该设置。如果他们链接到错误的域名，您将无法登录。

I'm trying to link my website with Facebook.

If I call the method in the PHP SDK called getLoginUrl(), it returns the correct login URL. This URL contains a number of parameters, one of which is my API key and it is correct. This is the URL that my Connect button is supposed to take me to.

However, when I actually click the Connect button on my site, a popup opens and says "Invalid API key specified". With a bit of inspection, I see that the URL in this popup says "api_key=undefined". In fact, the URL is completely different to what the login URL should be.

Any idea why this is happening? Only conflicts I can imagine are codeigniter or jQuery.

It's hard to be more specific. I'm guessing this will require good knowledge of the Facebook SDK to answer.

Thanks a lot. :)

解决方案

PHP should handle only login callback if necessary, login should be done through javascript.

FB api initialization:

<div id="fb-root"></div>
<script src="http://connect.facebook.net/en_US/all.js"></script>
<script>
    FB.init({
        appId  : appId,
        status : true,
        cookie : true,
        xfbml  : true
    });
</script>

Then you can trigger fb login dialog on some button:

FB.login(function(response) {
    //callback
}, {perms:'publish_stream'});

Also make sure you have correct settings in your fb app under "Connect" tab - "Connect URL" and "Base Domain" should be set. If they link to a wrong domain you won't be able to login.
