I came across this issue when running a wordpress web site. I tried all sorts of things to fix it and wasn't sure how, ultimately the issue was because I was using DNS forwarding with masking, and the links to external sites were not being addressed properly. i.e. my site was hosted at http://123.456.789/index.html but was masked to run at http://somewebSite.com/index.html. When i entered http://123.456.789/index.html in the browser clicking on those same links resulted in no X-frame-origins issues in the JS console, but running http://somewebSite.com/index.html did. In order to properly mask you must add your host's DNS name servers to your domain service, i.e. godaddy.com should have name servers of example, ns1.digitalocean.com, ns2.digitalocean.com, ns3.digitalocean.com, if you were using digitalocean.com as your hosting service.

如果在尝试嵌入Vimeo内容时遇到此错误，请更改iframe的src，从:https://vimeo.com/63534746更改为:http://player.vimeo.com/video/63534746

当我尝试在iframe中嵌入moodle 2时，我也有同样的问题，解决方案是站点管理►安全►HTTP安全并检查允许框架嵌入

我几乎尝试了所有的建议。然而，唯一真正解决这个问题的是:

在PHP文件所在的文件夹中创建一个.htaccess文件。 将这一行添加到htaccess: 报头总是不设置x帧选项

通过来自另一个域的iframe嵌入PHP之后应该可以工作。

此外，你可以在你的PHP文件的开头添加:

header('X-Frame-Options: ALLOW');

然而，在我的情况下，这是不必要的。

唯一一个有一堆答案的问题。欢迎来到这个指南，我希望我在最后期限那天晚上10:30为它工作时能有这个指南……facebook在canvas应用上做了一些奇怪的事情，好吧，你已经被警告过了。如果你还在这里，你有一个Rails应用程序将出现在Facebook Canvas后面，那么你将需要:

Gemfile:

gem "rack-facebook-signed-request", :git => 'git://github.com/cmer/rack-facebook-signed-request.git'

配置/ facebook.yml

facebook:
  key: "123123123123"
  secret: "123123123123123123secret12312"

配置/ application.rb

config.middleware.use Rack::Facebook::SignedRequest, app_id: "123123123123", secret: "123123123123123123secret12312", inject_facebook: false

配置/初始化/ omniauth.rb

OmniAuth.config.logger = Rails.logger
SERVICES = YAML.load(File.open("#{::Rails.root}/config/oauth.yml").read)
Rails.application.config.middleware.use OmniAuth::Builder do
  provider :facebook, SERVICES['facebook']['key'], SERVICES['facebook']['secret'], iframe:   true
end

application_controller.rb

before_filter :add_xframe
def add_xframe
  headers['X-Frame-Options'] = 'GOFORIT'
end

你需要一个控制器来调用Facebook的画布设置，我使用/canvas/，并使路由到这个应用程序的主SiteController:

class SiteController < ApplicationController
  def index
    @user = User.new
  end
  def canvas
    redirect_to '/auth/failure' if request.params['error'] == 'access_denied'
    url = params['code'] ? "/auth/facebook?signed_request=#{params['signed_request']}&state=canvas" : "/login"
    redirect_to url
  end
  def login
  end
end

login.html.erb

<% content_for :javascript do %>
  var oauth_url = 'https://www.facebook.com/dialog/oauth/';
  oauth_url += '?client_id=471466299609256';
  oauth_url += '&redirect_uri=' + encodeURIComponent('https://apps.facebook.com/wellbeingtracker/');
  oauth_url += '&scope=email,status_update,publish_stream';
console.log(oauth_url);
  top.location.href = oauth_url;
<% end %>

配置我认为来自omniauth的例子。 宝石文件(这是关键!!)来自:slideshare things i learned… 这个堆栈问题有整个Xframe的角度，所以你会得到一个空白，如果 你不需要把这个头文件放到应用控制器中。 我的男人@rafmagana写了这个heroku指南，现在你可以用这个答案来做轨道，也可以用巨人的肩膀走路。

FWIW:

当这个“破坏者”代码出现时，我们遇到了需要杀死iFrame的情况。因此，我使用PHP函数get_headers($url);在iFrame中显示远程URL之前检查它。为了获得更好的性能，我将结果缓存到一个文件中，这样就不会每次都建立HTTP连接。
