麻煩整合與科爾多瓦的應用程序Facebook驗證

Question

對不起，長職位，但我會在這裏堅果..

我一直坐在現在這個問題3天 - 我使用Javascript來寫一個混合移動應用我已經整合了Facebook登錄按鈕。我已經添加了Openfb.js api來處理我的master.js中的登錄和所需的功能。

Facebook身份驗證工作完美，它打開登錄頁面，具有特定應用程序所需的登錄頁面，並允許您登錄後，返回「成功」，你將被重定向到應用程序再次（inAppBrowser），但你不要登錄到應用程序，並引導到main.html中頁面..我從字面上手忙腳亂這裏和它快把我逼瘋了。

下面發起Facebook登錄按鈕被點擊時的功能：

function facebookLogin() { 
    showLoading(true); 
    openFB.login(
     function (response) { 
      if (response.status === 'connected') { 
       getFacebookInfo(); 
       //showMessage('Facebook login succeeded, got access token: ' + response.authResponse.token); 
      } else { 
       showMessage('Facebook login failed: ' + response.error); 
      } 
     }, 
    { scope: 'email' }); 
} 

在此之後是getFacebookInfo功能：

function getFacebookInfo() { 
    openFB.api({ 
     path: '/me', 
     success: function (facebookData) { 
      debugger; 
      var data = new Object(); 
      var now = new Date(); 

      var dataLogin = new Object(); 
      data.profilePicture = new Object(); 

      data.username = facebookData.first_name + ' ' + facebookData.last_name; 
      data.password = randomPassword(); 

      console.log(data.username); 
      data.email = facebookData.email; 
      data.gender = facebookData.gender; 
      data.firstName = facebookData.first_name; 
      data.surname = facebookData.last_name; 
      data.mode = 'facebook'; 
      var dt = new Date(); 
      data.dateOfBirth = dt.getFullYear() + '/' + (dt.getMonth() + 1) + '/' + dt.getDate(); 
      postData("users", data, successFacebookRegistration); 
      //getData("users", dataLogin, successLogin);    
     }, 
     error: function (data, obj) { 
      debugger; 
      showMessage('An error occurred acquiring account information from Facebook'); 
     } 
    }); 
} 

的OpenFB.js低於：

/** 
* OpenFB is a micro-library that lets you integrate your JavaScript application with Facebook. 
* OpenFB works for both BROWSER-BASED apps and CORDOVA/PHONEGAP apps. 
* This library has no dependency: You don't need (and shouldn't use) the Facebook SDK with this library. Whe running in 
* Cordova, you also don't need the Facebook Cordova plugin. There is also no dependency on jQuery. 
* OpenFB allows you to login to Facebook and execute any Facebook Graph API request.

它同時使用科爾多瓦，它不使用cookie和session狀態發揮好是我的經驗。我的直覺是，Facebook設置了一個身份驗證cookie--即時被刪除。 所以你可能會做的一切正確，只是科爾多瓦讓你過度。

因此，您可能必須編寫一個自定義插件，用於在webview之外存儲Facebook身份驗證狀態。

你針對iOS或Android，或兩者兼而有之？我知道在iOS上創建一個自定義Facebook插件來處理身份驗證實際上非常簡單（我自己也是這樣做的）。它存儲的認證狀態外的WebView的和應用程序數據本身，使切換頁面，即使它會記住驗證狀態。

需要說明的是，在我的iOS應用科爾多瓦大幅做工作後，科爾多瓦的多個漏洞已經開始越滾越大......並決定只寫它本身。 FOR IOS

自定義插件這裏假設你有關於插件如何對科爾多瓦工作在iOS的想法。此外，還包括如何分享別人的牆上鍛鍊活動代碼;）
