Android 自定义 URL 方案拒绝工作/OAuth 后如何导航回 Android 应用程序

Question

编辑，请看我在这个问题下面的第二个答案，以获得更简洁、更简单的问题显示

我终于无计可施了。我正在使用 titanium 开发跨平台应用程序（IOS 和 Android），并通过休息电话连接到 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！那么让我们开始吧。

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

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 "allow" 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，这是进行 salesforce 登录调用的地方
我的 AuthService.js 文件，这是在 index.js
my tiapp.xml 为 android 自定义 url 方案保存配置内容

index.js

var Auth = require('AuthService');

Auth.openLogin();

AuthService.js 只有"openLogin"函数在这里很重要。

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，我只包括我的 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>

向 Salesforce 注册的回调 Url：

我试过的： 我在这个问题上用谷歌搜索了自己。我的大部分修补工作都是对我的 "tiapp.xml" 进行调整，以更改 android 标签中这些属性的属性和值，以及对 [=90] 中的 "redirect_rui" 值进行许多调整=] 文件和 salesforce "callback 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，我查看并尝试了一些解决方案： https://gist.github.com/jasonkneen/5736738

你能不能试一试，看看是否可行。您还可以查看此 Git Post.

请求您尝试并告诉我们，如果这不起作用，那么我们可以尝试其他方法。

Answer 2

经过大约 64 小时的互联网搜索和无数次尝试，我终于找到了解决此问题的方法。耶我！我必须承认我对这个问题花了多长时间才解决感到有点羞愧。

问题： 在 salesforce 授权后无法找到导航回 android 应用程序的方法（自定义 url 方案非常痛苦 android).

解决方案：四处搜索后，我发现了一个来自 salesforce 的代码示例，它完成了我在这里尝试做的事情：

https://developer.salesforce.com/page/Developing_Mobile_Applications_with_Force.com_and_Appcelerator_Titanium

这是上面文章中提供的 github link，其中包含非常需要的代码：

https://github.com/appcelerator-developer-relations/Force

TLDR： 这里真正的关键是不要使用带有 android 和钛的自定义 url 方案。相反，上面列出的 github 代码在 web 视图中打开 auth 页面，然后使用侦听器在 auth 完成后关闭该 webview 并打开您需要的任何视图。

说明： 要在 IOS 上导航回我的应用程序，我所要做的就是按顺序在我的 tiapp.xml 文件中添加几行使用自定义 url 方案。它工作得非常迅速和简单，没有任何头痛。自然地，我假设自定义 url 方案是 android 的方式，简单吧？错误的。我花了很多时间如上所述尝试在 android 上制作自定义 url 方案但无济于事。网上似乎有很多关于 android 自定义 url 方案的信息，但其中 none 对我有用，相信我，我尝试了很多东西（毕竟它大约需要 64 小时） .最后我只是试图在网上找到一个代码示例来完成我想要的。这是我找到的那个。

Answer 3

在为模式识别设置清单方面，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>

然后我会在那个 activity 中有一个方法可以检查您的架构是否在意图中。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 显示意图 。这实际上意味着在浏览器中输入 url 并按 go 将不起作用。它仅在用户单击 link 或您触发意图时触发。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;
    }

} );

Answer 4

有一些在我看来合法的解决方法。因此，与 shouldOverrideUrlLoading() 一起，WebViewClient 允许覆盖 onErrorRecieved() 并且实际上它将 failingUrl 作为参数传递。

private val webViewClient = object : WebViewClient() {

        @Suppress("OverridingDeprecatedMember")
        override fun onReceivedError(view: WebView?, errorCode: Int, description: String?, failingUrl: String?) {
