如何使用重定向帆布授权的Facebook应用程序？ [英] How to authorize Facebook app using redirect in canvas?

问题描述

我试图进入使得Facebook应用程序，但我遇到了麻烦授权在画布里面一个重定向方案工作。

I'm trying to get into making Facebook apps but I'm having trouble getting authorization working in a redirect scheme inside the canvas.

使用JavaScript API，我得到了它在弹出方案轻松的工作pretty：

Using the javascript api, I got it working pretty easily in a popup scheme:

$("#loginButton").click(function(e) {
    FB.login(function(response) {
        if (response.perms) {
            perms();
        }
}, {perms : 'publish_stream'});

不过，在弹出的应该是一个不必要的额外的点击，因为每一个其它应用我看甚至呈现你的登陆页面之前请求授权。像这样的：

But the popup should be an unnecessary extra click, because every other application I see requests the authorization before even showing you the landing page. Like this:

我的身影，他们只是使用重定向方案。所以，我整天都在尝试不同的方法我可以找到：

I figure they're simply using a redirect scheme. So I spent the entire day trying the different ways I could find:

header("Location: https://graph.facebook.com/oauth/authorize?client_id=" . $gAppId . "&redirect_uri=" . urlencode($gUrl) . "&perms=publish_stream");

header("Location: http://www.facebook.com/login.php?v=1.0&api_key=" . $gApiKey . "&next=" . urlencode($gUrl) . "&canvas=");

header("Location: http://www.facebook.com/connect/uiserver.php?app_id=" . $gAppId . "&next=" . urlencode($gUrl) . "&return_session=0&fbconnect=0&canvas=1&legacy_return=1&method=permissions.request");

但所有的人，而不是显示的授权请求的东西，表明这样一个链接：

But all of them, instead of showing the authorization request stuff, show a link like this:

欢快的，如果我在新标签中打开的iframe的地址，我得到的授权请求像我想要的。但我想它立即显示，不需要额外的点击，像所有其他应用程序。

Hilariously, if I open the iframe's address in a new tab, I get the authorization request like I wanted. But I want it to display immediately, without an extra click, like every other app.

下面是一个应用程序，是做授权，要求所有在一气呵成的权限，以重定向形式的例子，甚至显示登陆页面之前：

Here's an example of an app that is doing authorization and requesting permissions all in one go, in redirect form, before even displaying the landing page:

www.facebook.com/send.fortune.cookies

www.facebook.com/send.fortune.cookies

他们是如何做的？

推荐答案

我知道这是个月大，现在......但是这是你应该做的添加权限检查到你的画布。

I know that this is months old now... but this is what you should do to add permission checking to your canvas.

if ($session) {
  try {
    $uid = $facebook->getUser();
    $me = $facebook->api('/me');
    $accesstoken=$session['access_token'];
  } catch (FacebookApiException $e) {
    error_log($e);
  }
} 

if($me)
{
   // do what you have to do
}else {
    $loginUrl = $facebook->getLoginUrl(
        array(
            'canvas' => 1,
            'fbconnect' => 0,
            'req_perms' => 'publish_stream'
        )
    );
    echo '<script>top.location="'.$loginUrl.'";</script>';
    //echo '<fb:redirect url="' . $loginUrl . '" />';
   //header('Location: '.$loginUrl);
}
