Omniauth Facebook authentication on localhost
提问by Ryan Foster
I am trying to set up Omniauth as described in this Railscast. While it works with Twitter, I am unable to get it working with Facebook. I also set up 'http://localhost:3000' as siteurl and 'localhost' as domain but still see the following error message in the browser:
我正在尝试按照Railscast 中的描述设置 Omniauth 。虽然它适用于 Twitter，但我无法让它与 Facebook 一起使用。我还设置了 ' http://localhost:3000' 作为 siteurl 和 'localhost' 作为域，但仍然在浏览器中看到以下错误消息：
Invalid redirect_uri: Given URL is not allowed by the Application configuration.
Does anyone of you have any suggestions on how to fix this? Thanks in advance.
你们中有人对如何解决这个问题有任何建议吗？提前致谢。

Take a look at the redirect in the URI. Mine read localhost:3000 so I changed the Site URL to "http://localhost:3000/" and it worked.
查看 URI 中的重定向。我的读取 localhost:3000 所以我将站点 URL 更改为“http://localhost:3000/”并且它起作用了。

Here's what worked for me.
这对我有用。
Right now Facebook does not allow setting the Site Domain to an IP, so it's not possible to set the Site URL to http://127.0.0.1:3000/because then Facebook will complain that the URL does not match the domain.
现在 Facebook 不允许将站点域设置为 IP，因此无法将站点 URL 设置为 IP，http://127.0.0.1:3000/因为 Facebook 会抱怨 URL 与域不匹配。
So in your Facebook App set the:
所以在你的 Facebook 应用程序中设置：
Site URL: http://localhost:3000/
Domain: localhost
When you access the app on your dev machine make sure you type in localhost:3000 in the browser. If you use 127.0.0.1:3000 OmniAuth will use that in the callback url it sends to Facebook and then Facebook will throw the error Ryan mentions above.
当您在开发机器上访问应用程序时，请确保在浏览器中输入 localhost:3000。如果您使用 127.0.0.1:3000 OmniAuth 将在它发送到 Facebook 的回调 url 中使用它，然后 Facebook 将抛出上面 Ryan 提到的错误。

I switch to http://lvh.me:3000in my local browser to test facebook locally. Then in facebook app settings, make lvh.me your domain.
我在本地浏览器中切换到http://lvh.me:3000以在本地测试 facebook。然后在 facebook 应用程序设置中，将 lvh.me 设为您的域。
lvh.me is a registered domain pointing to 127.0.0.1 that a developer bought to test subdomains locally.
lvh.me 是指向 127.0.0.1 的注册域名，开发人员购买该域名是为了在本地测试子域名。

Try using
尝试使用
http://0.0.0.0:3000/
for the 'Site URL'. This works for me. (Also, I don't have anything in the 'Site Domain' field.)
对于“站点 URL”。这对我有用。（此外，我在“站点域”字段中没有任何内容。）

If you are on OSX you can use pow http://pow.cx/to rename localhost to
如果您使用的是 OSX，则可以使用 pow http://pow.cx/将 localhost 重命名为
http://yourapp-dev
(is not really renamed, it's added)
（没有真正重命名，它是添加的）
you can set that as a valid domain name on facebook.
您可以将其设置为 Facebook 上的有效域名。
