如何将Facebook评论添加到单页应用程序

回答晚了，但也许它会帮助某人。对我来说，在单页应用程序上呈现独特的 fb 注释的关键是FB.XFBML.parse();

每次我想呈现独特的评论时：

1. 更改网址，每个fb评论线程分配给特定的网址所以我可能有 www.someurl.com/#123、www.someurl.com/#456、www.someurl.com/#789，每个都有自己的 fb 评论线程。在AngularJs中，这可以通过$location.hash('123');

来完成

2. 创建一个新的 fb 注释div，其中"数字"等于"123"、"456"或"789"

   <div class="fb-comments" data-href="http://someurl.com/#{{number}}" data-numposts="5" data-width="100%" data-colorscheme="light"> </div>

3. 调用执行 fb SDK 的函数

   function FBfun(path) {
     setTimeout(function() { // I'm executing this just slightly after step 2 completes
       window.fbAsyncInit = function() {
         FB.init({
           appId : '123456789123',
           xfbml      : true,
           version    : 'v2.2'
         });
       };
       (function(d, s, id){
         var js, fjs = d.getElementsByTagName(s)[0];
         if (d.getElementById(id)) {return;}
         js = d.createElement(s); js.id = id;
         js.src = "//connect.facebook.net/en_US/sdk.js";
         fjs.parentNode.insertBefore(js, fjs);
       }(document, 'script', 'facebook-jssdk'));
       FB.XFBML.parse(); // This is key for all this to work!
     }, 100);
   }
   

我将脚本添加到应用程序中.js例如

   initializeFB: function () {
        if (!isFBInitialized.isInitialized) {
            FB.init({
                appId: 'xxxxxxxxxxxx',
                appSecret: 'xxxxxxxxxxxxxxx',
                // App ID from the app dashboard
                channelUrl: '//mysite//channel.html', // Channel file for x-domain comms
                status: true,                                 // Check Facebook Login status
                cookie: true, // enable cookies to allow the server to access the session
                xfbml: true                                  // Look for social XFBML plugins on the page to be parsed
            });

            (function (d, s, id) {
                var js, fjs = d.getElementsByTagName(s)[0];
                if (d.getElementById(id)) { return; }
                js = d.createElement(s); js.id = id;
                js.src = "//connect.facebook.net/en_US/all.js";
                fjs.parentNode.insertBefore(js, fjs);
            }(document, 'script', 'facebook-jssdk'));
            // Here we subscribe to the auth.authResponseChange JavaScript event. This event is fired
            // for any auth related change, such as login, logout or session refresh. This means that
            // whenever someone who was previously logged out tries to log in again, the correct case below 
            // will be handled. 
            FB.Event.subscribe('auth.authResponseChange', function (response) {
                // Here we specify what we do with the response anytime this event occurs. 
                if (response.status === 'connected') {
                    // The response object is returned with a status field that lets the app know the current
                    // login status of the person. In this case, we're handling the situation where they 
                    // have logged in to the app.
                    testFBAPI();
                } else if (response.status === 'not_authorized') {
                    // In this case, the person is logged into Facebook, but not into the app, so we call
                    // FB.login() to prompt them to do so. 
                    // In real-life usage, you wouldn't want to immediately prompt someone to login 
                    // like this, for two reasons:
                    // (1) JavaScript created popup windows are blocked by most browsers unless they 
                    // result from direct user interaction (such as a mouse click)
                    // (2) it is a bad experience to be continually prompted to login upon page load.
                    FB.login();
                } else {
                    // In this case, the person is not logged into Facebook, so we call the login() 
                    // function to prompt them to do so. Note that at this stage there is no indication
                    // of whether they are logged into the app. If they aren't then they'll see the Login
                    // dialog right after they log in to Facebook. 
                    // The same caveats as above apply to the FB.login() call here.
                    FB.login();
                }
            });
            isFBInitialized.isInitialized = true;
        }
    },

并在视图中调用它附加如

             app.initializeFB();

那么它工作得很好

我的 React 应用程序的步骤 3 变为（更友好）：

componentDidMount() {
    window.fbAsyncInit = () => {
        window.FB.init({
            appId: '572831199822299',
            xfbml: true,
            version: 'v4.0',
        });
    };
    (function (d, s, id) {
        const fjs = d.getElementsByTagName(s)[0];
        if (d.getElementById(id)) { return; }
        const js = d.createElement(s);
        js.id = id;
        js.src = '//connect.facebook.net/ru_RU/sdk.js';
        fjs.parentNode.insertBefore(js, fjs);
    }(document, 'script', 'facebook-jssdk'));
    setTimeout(() => {
        window.FB.XFBML.parse();
    }, 100);
}
