提示共享用户安装应用

Question

我正在使用Google Drive SDK，我制作了一个带共享功能的简单应用。遗憾的是，当文档与未安装我的应用程序的用户共享时，系统会提示他们显示以下消息：

You do not have StoryPad installed
This item was created with StoryPad, a Google Drive app you have not installed.

但是，他们没有看到安装此应用的链接或选项。有没有办法配置它，以便提示他们在这个屏幕上安装？我不希望用户不得不四处寻找安装此应用程序的方法，因为他们会离开。

以下是它的外观截图：

查看Google Drive SDK文档，在error handling section中，您似乎捕获了错误：

 `403: The authenticated user has not installed the app with client id {clientId}
 The user has not installed the requesting app, or has uninstalled it.`

记录的建议行动是：

 Direct the user to the Chrome Web Store to install the app.

您没有列出您正在使用的语言，因此JavaScript中的示例（上述引用页面中也列出了其他语言）可能是：

request.execute(function(resp) {
    if (!resp.error) {

      //Excellent, everything is working correctly! Proceed to show your file.

    } else {

      console.log('Error code: ' + resp.error.code);

      if (resp.error.reason == "appNotInstalled") {

        //Here is where you implement the action to inform the user where to download your app.
        alert("You need to install StoryBoard to view this file! Please proceed here: http://<link to your app>");

      }

      // More error information can be retrieved with resp.error.errors.
    }
});
