Android 自定义 URL 方案拒绝工作/如何在 OAuth 之后导航回 Android 应用程序

Question

编辑，请查看我在这个问题下方的第二个答案，以获得更简洁、更简单的问题显示

---

我终于忍无可忍了。我正在使用 titanium 开发跨平台应用程序(IOS 和 Android)，并通过 rest 调用连接到 salesforce api。我在这个问题上花了 3 天 20 个小时，但仍然卡住了。任何支持将不胜感激!因此，让我们开始吧。

我想要它做什么:该应用程序启动，检查用户是否已使用 oauth2 授权获得 token ，如果没有，则向用户提供 salesforce 登录屏幕。用户输入凭据并点击“允许”按钮，然后我们被重定向回应用。

问题:从上面我想要它做的事情的描述来看，除了最后一行以粗体显示外，其他一切都有效。一旦用户点击“允许”按钮，我们就会收到这个未知的 url 方案错误:

代码:该代码几乎由 3 个不同的重要区域组成

• 我的 index.js 文件，这是调用 salesforce 登录的地方
• 我的 AuthService.js 文件，它是在 index.js 中调用 salesforce url 信息的地方
• 我的 tiapp.xml，其中包含 android 自定义 url 方案的配置内容

index.js

var Auth = require('AuthService');

Auth.openLogin();

AuthService.js 只有“openLogin”功能在这里非常重要。

var loginWindow;

module.exports = {

  get: function () {
    console.log("made it into the auth.get function");
    return Ti.App.Properties.getObject('auth');
  },

  set: function (data) {
    Ti.App.Properties.setObject('auth', data);
    console.log("auth set function was executed!!!");
  },

  erase: function () {
    Ti.App.Properties.removeProperty('auth');
  },

  openLogin: function () {

    console.log("made it into openLogin!!");


   var webview = Titanium.UI.createWebView({url:'https://login.salesforce.com/services/oauth2/authorize' +
      '?response_type=token&display=touch' +
      '&redirect_uri=testapp://app.open' +
      '&client_id=' + Ti.App.Properties.getString('salesforce_client_id')});


      //console.log("Webview URL: " + webview.getUrl());

    loginWindow = Titanium.UI.createWindow();
    loginWindow.add(webview);
    loginWindow.open({modal:true});



    // attempt to log url to console here
    //console.log("this is the webview URL during callback: " +  webview.getUrl());

  },

  closeLogin: function () {
    loginWindow.close();
  }

};

tiapp.xml 为了简洁起见，我只包含了我的 android 部分

<android xmlns:android="http://schemas.android.com/apk/res/android"> 
        <manifest android:versionCode="1" android:versionName="1.00">
            <uses-permission android:name="android.permission.INTERNET"></uses-permission>
            <uses-permission android:name="android.permission.ACCESS_NETWORK_STATE"></uses-permission>
            <uses-permission android:name="android.permission.ACCESS_COARSE_LOCATION"></uses-permission>
            <uses-permission android:name="android.permission.ACCESS_FINE_LOCATION"></uses-permission>
            <uses-permission android:name="android.permission.ACCESS_WIFI_STATE"></uses-permission>
        </manifest>


        <activity
      android:name=".TesterActivity"
      android:exported="true"
      android:label="@string/app_name" >
      <intent-filter>
          <data android:host="app.open" android:scheme="testapp" />
          <action android:name="android.intent.action.VIEW" />
          <category android:name="android.intent.category.BROWSABLE" />
          <category android:name="android.intent.category.DEFAULT" />
      </intent-filter>
  </activity>

    </android>

在 Salesforce 中注册的回调 Url:

我尝试过的:我在这个问题上用谷歌搜索了自己。我的大部分修补工作是对我的“tiapp.xml”进行调整，以更改 android 标记中这些属性的属性和值，以及对“AuthService.js”文件和 salesforce 中的“redirect_rui”值进行许多调整“回调 url”字段(因为这些值必须匹配，否则会出现 uri 不匹配错误)。

为了解决我的问题，以下是我看过并尝试过的一些解决方案: https://gist.github.com/jasonkneen/5736738

Answer 1

在为模式识别设置 list 方面，您最终应该得到类似于以下内容的内容

<manifest ...>
    ...
    <application ...>
        ...
        <activity ...
            android:exported="true"> <!-- Make it exported -->
            <intent-filter>
                <action android:name="android.intent.action.MAIN" />
                <category android:name="android.intent.category.LAUNCHER" />
            </intent-filter>
            <intent-filter android:label="...">
                <action android:name="android.intent.action.VIEW" />
                <category android:name="android.intent.category.DEFAULT" />
                <category android:name="android.intent.category.BROWSABLE" />
                <data android:scheme="testapp" />
                <data android:host="app" /> <!-- cover all your bases -->
                <data android:host="app.open" />
            </intent-filter>
        </activity>
    </application>
</manifest>

然后我会在该 Activity 中有一个方法可以检查您的模式是否在 Intent 中。类似于以下内容:

protected void onCreate(final Bundle savedInstanceState) {
    ...
    checkIntent( getIntent() );
} 

protected void onNewIntent(final Intent intent) {
    ...
    checkIntent( intent );
}

private void checkIntent(Intent intent) {
    if ( intent.getDataString() != null && Intent.ACTION_VIEW.equals(intent.getAction()) ) {
        //If we reached here we have some kind of deep link or custom schema
        //so lets identify which schema
        if ( "testapp".equals(data.getScheme().toLowerCase()) ) {
            //my tests were able to reach here
        }
    }
}

Android 的一个怪癖是，对于更高版本，用户必须显示 Intent 。这实际上意味着在浏览器中输入 url 并按 go 是行不通的。它仅在用户单击链接或您触发 Intent 时触发。当您只想检测来自您自己的 WebView(而不是外部浏览器)的重定向时，您可以解决这个问题:

myWebView.setWebViewClient( new WebViewClient() {

    @Override
    public boolean shouldOverrideUrlLoading(WebView view, String url) {
        if (url.startsWith("testapp://")) {
            Intent intent = new Intent(Intent.ACTION_VIEW);
            intent.setData( Uri.parse(url) );
            view.getContext().startActivity( intent );
            return true; //with return true, the webview wont try rendering the url
        }
        return false;
    }

} );
