Question

UPDATE:

最后，我最终通过Eclipse使用apache cordova/phonegap for android和xcode for iOS。这是唯一适用于我首选设置的解决方案。

Previous post:

我想在我的混合应用程序中实现facebook登录。我已经在facebook文档中做了很少的研究，但我没有发现任何有用的东西。如果你能给我一些提示，那将非常有帮助。我将奖励那些可以告诉我该怎么做的人的赏金。

我不想通过Phonegap / cordova和其他框架，因为我需要花费大量时间来研究这些框架。

Hybrid apps - like native apps, run on the device, and are written with web technologies (HTML5, CSS and JavaScript). Hybrid apps run inside a native container, and leverage the device’s browser engine (but not the browser) to render the HTML and process the JavaScript locally. A web-to-native abstraction layer enables access to device capabilities that are not accessible in Mobile Web applications, such as the accelerometer, camera and local storage.

如果有人有任何解决方案并愿意提供帮助，请告诉我。

我尝试过Javascript SDK，但没有运气。

代码：

<div id="fb-root"></div>
<script>
 window.fbAsyncInit = function() {
  FB.init({
    appId      : 'xxxx', // App ID
    channelUrl : '//xxxx/channel.html', // Channel File
    status     : true, // check login status
    cookie     : true, // enable cookies to allow the server to access the session
    xfbml      : true  // parse XFBML
  });

  // Here we subscribe to the auth.authResponseChange JavaScript event. This event is fired
  // for any authentication 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.     
      testAPI();
    } 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 interaction from people using the app (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();
    }
  });
  };

  // Load the SDK asynchronously
  (function(d){
   var js, id = 'facebook-jssdk', ref = d.getElementsByTagName('script')[0];
   if (d.getElementById(id)) {return;}
   js = d.createElement('script'); js.id = id; js.async = true;
   /* js.src = "//connect.facebook.net/en_US/all.js"; */
   js.src="https://connect.facebook.net/en_US/all.js";
   ref.parentNode.insertBefore(js, ref);
  }(document));

  // Here we run a very simple test of the Graph API after login is successful. 
  // This testAPI() function is only called in those cases. 
  function testAPI() {
    console.log('Welcome!  Fetching your information.... ');
    FB.api('/me', function(response) {
      console.log('Good to see you, ' + response.name + '.');
    });
  }
</script>

<!--
  Below we include the Login Button social plugin. This button uses the JavaScript SDK to
  present a graphical Login button that triggers the FB.login() function when clicked.

<!-- <fb:login-button show-faces="true" width="200" max-rows="1"></fb:login-button> -->

<!-- End script of Facebook Login -->

Answer 1

Facebook app details 您目前是在本地计算机上测试它还是在服务器上托管HTML？如果在服务器上 - 您的域名是什么？

在应用领域更新它（见图）
在“使用Facebook登录的网站”
用于测试问题，从testAPI（）中删除FB.api调用。只是发出警报。
从标准浏览器进行测试。如果它有效 - 你的FB定义没有任何问题。

Answer 2

而不是FB.Event.subscribe

使用 FB.getLoginStatus

FB.getLoginStatus(function(response) {
  if (response.status === 'connected') {
    // the user is logged in and has authenticated your
    // app, and response.authResponse supplies
    // the user's ID, a valid access token, a signed
    // request, and the time the access token 
    // and signed request each expire
    var uid = response.authResponse.userID;
    var accessToken = response.authResponse.accessToken;

    FB.api('/me', function(response) {
        console.log(response);
    }); 

  } else if (response.status === 'not_authorized') {
    // the user is logged in to Facebook, 
    // but has not authenticated your app
  } else {
    // the user isn't logged in to Facebook.
  }
 });

我偶然发现了一个不同的解决方案，它对我来说非常好用，甚至更好，没有本机代码库！这里的诀窍是绕过Facebook JavaScript SDK库并直接使用Facebook REST api端点。

我正在使用OpenFB javascript库（https://github.com/ccoenraets/OpenFB）来简化这项工作，而不是自己编写调用，但你可以这样做。我已经概述了如何让它在下面工作的步骤。

1）创建一个Facebook应用并更新基本和高级下的URL设置，以允许使用Facebook或您的本地网址进行回调。然后复制Facebook ID准备好下一步

2）如果您还没有，请下载并安装Cordova以将工具放入命令行。然后导航到您的Sites文件夹并运行以下命令来创建项目并添加您的平台：

cordova create your-project-name
cordova platform add ios
cordova platform add android

3）现在我们需要添加一个Cordova插件来处理来自facebook登录的弹出窗口。要添加插件，请使用以下命令：

cordova plugin add org.apache.cordova.inappbrowser

4）现在我们只需要在新的Cordova项目中下载和配置OpenFB。对于此示例，我们将使用它们提供的测试页面，因此从OpenFB Github页面下载它并将文件解压缩到cordova项目/ www /文件夹中。在此之后打开index.html并使用步骤1中的Facebook App ID编辑以下行：

openFB.init({appId: 'YOUR_FB_APP_ID'});

5）您现在应该可以运行示例并使用本地浏览器设置登录。

6）要在iOS模拟器上进行测试，您需要安装xCode，然后运行命令：

cordova emulate ios

要在Android模拟器上进行测试，您需要安装Android SDK，然后运行命令：

cordova emulate android

要在连接有线缆的iOS设备上进行测试，请运行以下命令：

cordova run ios

要在连接有线缆的Android设备上进行测试，请运行以下命令：

cordova run android
