如果用户喜欢某个页面，如何发布到新闻Feed？ [英] How to post to a news feed if a user has liked a page?

问题描述

最近，我听说，通过Facebook Open Graph API，可以发布如果用户喜欢某个页面，可以使用该用户的新闻稿。

我一直尽力跟随该示例，并且创建了一个虚拟页面。

As根据我的理解，有必要做以下事情：

1. 创建必要的Open Graph标签，包括您的Facebook应用程序
   
   
   
   
   • 我已经使用 Open Graph Debugger
   
   


2. 在页面上添加一个相似的按钮


3. '像'页面



4. 获取访问令牌发布消息）

     curl -F grant_type = client_credentials -F client_id = MY_APP_ID -F client_secret = MY_APP_SECRET -F redirect_uri = https：//graph.facebook.com/oauth/access_token https://graph.facebook.com/oauth / access_token 
     




5. 发布到Feed

   
   
   -F'message = Hello Likers'-F'id = http：//dl.dropbox.com/u/3618086/test.html
   'https://graph.facebook.com/feed
   

在这一点上，消息应该发送给喜欢该页面的任何人。相反，我收到以下错误：

  {
error：{
message （＃100）http：\ / \ / dl.dropbox.com\ / u\ / 3618086\ / / test.html无法解析为有效的用户ID，
type： OAuthException，
code：100 
} 
} 
  

在这一点上，我很困惑。我已阅读了以下相关问题：

• / li>
  

• 如何以编程方式发布到与喜欢页面相关联的Facebook Feed？


• Facebook例外＃100：无法解析为有效的用户ID


• 如何以编程方式发布到一个喜欢的网页的Facebook Feed？


• 无法发布到Facebook feed

并尝试了他们的建议，但没有任何成功。我错过了哪一步？

我可以提供更多的细节;我只是不想要这个问题太久了。

解决方案

好吧，我想出了我的问题。我在下面列出我的解决方案，以获得别人的利益。

上面列出的步骤确实是正确的，但有一些事情需要进一步解释

发布给喜欢Facebook上的项目的人

步骤1 ：创建Facebook应用程序

• 您需要访问 Facebook Developers 页面，并创建一个新的应用程序
  
  
  
  • 您不应该需要一个命名空间或应用程序的webhosting
  
  


• 填写您的申请资料
  
  
  
  • 主要地，您需要选择 Facebook登入。 站点URL 应与您的站点托管的位置相同。在我的例子中，我正在托管我的保管箱共享文件夹，所以我使用 http://dropbox.com
  
  
  • 设置你的应用程序域到您的站点URL的主机名。在我的情况下，这是 dropbox.com ，这将允许Facebook使用 *。dropbox.com 。我也可以特别做到 dl.dropbox.com
  
  

步骤2：创建虚拟页面

创建虚拟页面非常重要。我发现我的大部分问题是由初始页面设置错误引起的。如果你创建一个虚拟页面，你可以尝试（或至少创建另一个虚拟页面）直到一切正常。

• Make确保您的页面正确，特别是打开的图形标签。 正确是什么样子？您可以查看我的虚拟页面，但我已经包含< HEAD> 以下：

    <？xml version =1.0 = UTF-8 >？; 
  <！DOCTYPE html PUBLIC -  // W3C // DTD XHTML 1.0 Strict // ENhttp://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd\"> 
  < html lang =enxml：lang =enxmlns =http://www.w3.org/1999/xhtmlxmlns：fb =http://www.facebook.com / 2008 / fbmlxmlns：og =http://ogp.me/ns#> 
  < head> 
  < title>测试< / title> 
  < link href =http://dl.dropbox.com/u/3618086/test2.html =canonical/> 
  < meta property =fb：app_idcontent =YOUR_APP_ID> 
   
  < meta property =og：typecontent =product> 
  < meta property =og：titlecontent =PAGE TITLE/> 
  < meta property =og：descriptioncontent =PAGE DESCRIPTION/> 
  < meta property =og：imagecontent =http://www.stanford.edu/group/cardinalballet/Pictures/WebsitePics/portrait-placeholder.jpg> 
   
  < meta property =og：site_namecontent =SITE_NAME/> 
  < meta property =og：urlcontent =http://dl.dropbox.com/u/3618086/test2.html> 
  < / head> 
    

  
  
  

  
  
  • 这个关键的部分是 fb ：app_id （应该是您的Facebook应用程序ID），而 og：type 。有多个类型，某些没有发布权限。有关详细信息，请访问 Open Graph API文档。我最初喜欢我的页面，当它是一篇文章，这引起了我的许多问题。
  
  
  • 您还可以使用 Open Graph Debugger
  
  



• 将类似按钮添加到页面，以及Facebook SDK。

步骤3：像页面

整个过程中最直接的部分。访问您的虚拟页面，然后按 按钮。

步骤4：发送消息

假设您已经正确完成了以前的步骤，最后一点也应该是直截了当的。我在我的例子中使用 curl ，但您应该可以使用任何POST请求获取它。

• 获取访问令牌。

    curl -F grant_type = client_credentials -F client_id = MY_APP_ID -F client_secret = MY_APP_SECRET -F redirect_uri = https：// graph。 facebook.com/oauth/access_token https://graph.facebook.com/oauth/access_token 
    




• 获取产品页面的ID。

    curl -g https://graph.facebook.com/\？ id \ = PAGE_URL 
    




• 向喜欢您的产品页面的所有人发送消息。 / p>
  
  

    curl -F'access_token = ACCESS_TOKEN'-F'message = MESSAGE'-F'id = ID_FROM_PREVIOUS_ACTION'https：// graph 
   
   $ h 
   
   
   
   
  步骤5：成功！
   
   
   
  在这一点上，希望一切顺利。作为喜欢该页面的用户，请查看他们的新闻资讯。您应该看到一个帖子，其中包含您的页面上的标题，图像和描述。 Hooray。
   
   
   
   ...这就是我如何解决它。希望这对其他人来说是有价值的。如果我错过了任何细节，我会很乐意。
   
  Recently, I heard that, with the Facebook Open Graph API, it is possible to post to a user's newsfeed if they have liked a page.
  
  I have been trying my best to follow along with the example, and have created a dummy page.
  
  As far as I understand it, it is necessary to do the following:
  
  Create the necessary Open Graph tags, including the one for your Facebook app
  
  
  I've tested it using the Open Graph Debugger
  
  Add a like button to the page
  'Like' the page
  Obtain an access token (to post the message)
  curl -F grant_type=client_credentials -F client_id=MY_APP_ID -F client_secret=MY_APP_SECRET -F redirect_uri=https://graph.facebook.com/oauth/access_token https://graph.facebook.com/oauth/access_token
  
  Post to the feed
  curl -F 'access_token=ACCESS_TOKEN_FROM_STEP_4' -F 'message=Hello Likers' -F 'id=http://dl.dropbox.com/u/3618086/test.html' https://graph.facebook.com/feed
  
  It's at this point that the message should be sent to anyone who liked the page. Instead, I get the following error:
  {
      "error": {
          "message": "(#100) http:\/\/dl.dropbox.com\/u\/3618086\/test.html does not resolve to a valid user ID",
          "type": "OAuthException",
          "code":100
      }
  }
  It's at this point that I'm confused. I've read through these related questions:
  
  
  How do I publish to the group of people who liked a webpage or object?
  How do you programmatically publish to the Facebook feed associated with a 'liked' page?
  Facebook Exception #100 : Does not resolve to a valid user ID
  How to programmatically publish to a facebook feed for a liked webpage?
  Unable to publish to facebook feed
  
  
  And have tried their suggestions, but nothing has been successful. What step am I missing?
  
  I can provide further details; I just didn't want the question to get too long.
  解决方案
  Alright, I figured out my problem. I'm including my solution below for the benefit of others.
  
  The steps I've listed above are indeed correct, but there are a few things that warrant further explanation to avoid the pitfalls that I fell into.
  
  Posting to people who have liked an item on Facebook
  
  Step 1: Create a Facebook App
  
  
  You'll need to visit the Facebook Developers page and create a new application
  
  You should not need a namespace, or webhosting for your application
  
  Fill out the details for your application
  
  Primarily, you'll need to select "Website with Facebook Login". The site URL should be the same as where your site is hosted. In my example, I am hosting in my dropbox shared folder, so I used http://dropbox.com
  Set your App Domain to the hostname of your site URL. In my case, this is dropbox.com which will allow Facebook to use *.dropbox.com. I also could have done dl.dropbox.com specifically.
  
  
  
  Step 2: Create the dummy page
  
  It is very important that you create a dummy page. I found that most of my problems were caused by setting up the initial page wrong. If you create a dummy page, you can experiment (or at least create another dummy page) until everything is working.
  
  
  Make sure that your page is correct, especially the open graph tags. What does correct look like? You can check out my dummy page, but I've included the <HEAD> below:
  <?xml version="1.0" encoding="UTF-8"?>
  <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
  <html lang="en" xml:lang="en" xmlns="http://www.w3.org/1999/xhtml" xmlns:fb="http://www.facebook.com/2008/fbml" xmlns:og="http://ogp.me/ns#">
  <head>
      <title>Test</title>
      <link href="http://dl.dropbox.com/u/3618086/test2.html" rel="canonical" />
      <meta property="fb:app_id" content="YOUR_APP_ID">
  
      <meta property="og:type" content="product">
      <meta property="og:title" content="PAGE TITLE" /> 
      <meta property="og:description" content="PAGE DESCRIPTION" /> 
      <meta property="og:image" content="http://www.stanford.edu/group/cardinalballet/Pictures/WebsitePics/portrait-placeholder.jpg">
  
      <meta property="og:site_name" content="SITE_NAME"/>
      <meta property="og:url" content="http://dl.dropbox.com/u/3618086/test2.html">
  </head>
  
  
  
  The critical piece of this are the fb:app_id (which should be your Facebook application id), and og:type. There are multiple types, and certain ones don't have publish permissions. For more information, visit the Open Graph API documentation. I initially liked my page when it was an article, which caused many of the problems that I had.
  You can also check the page for Open Graph errors using the Open Graph Debugger
  
  Add the like button to the page, along with the Facebook SDK.
  
  
  Step 3: Like the page
  
  The most straightforward part of the entire process. Visit your dummy page, and press the Like button.
  
  Step 4: Send a message
  
  Assuming that you've done the previous steps correctly, the last bit should also be straightforward. I use curl in my example, but you should be able to get it using any sort of POST request.
  
  
  Obtain an access token. 
  curl -F grant_type=client_credentials -F client_id=MY_APP_ID -F client_secret=MY_APP_SECRET -F redirect_uri=https://graph.facebook.com/oauth/access_token https://graph.facebook.com/oauth/access_token
  
  Obtain the id of your product page.
  curl -g https://graph.facebook.com/\?id\=PAGE_URL
  
  Post a message to all people who liked your product page.
  curl -F 'access_token=ACCESS_TOKEN' -F 'message=MESSAGE' -F 'id=ID_FROM_PREVIOUS_ACTION' https://graph.facebook.com/feed
  
  
  
  Step 5: Success!
  
  At this point, hopefully everything has gone well. As the user who liked the page, check out their news feed. You should see a post with the title, image, and description that were on your page. Hooray.
  
  ...And that's how I solved it. Hopefully this will be valuable to other people. I would be glad to elaborate if I have missed any details.
