用于AppEngine的RESTFul服务框架 [英] RESTFul Service Framework for AppEngine

问题描述

我正在研究一个涉及Google AppEngine PAAS的移动和网络客户端的项目。我希望在我的AppEngine应用程序中使用RESTFul web服务。我已经浏览了Stackoverflow，以了解可以与AppEngine一起使用的RESTFul服务框架（GWT）和移动（Android）客户端。尽管 Restlet 似乎为AppEngine，GWT和Android提供了版本，但到目前为止，我已经将其降至 RestEasy 主要由于此问题。

以前有一些问题，讨论RESTFul框架 a>但我认为这种比较不适用于此，现在很常见。听到有经验的开发人员对这套平台可用的框架以及优点和缺点的看法是有帮助的。

解决方案

您可能希望考虑使用 Google Cloud Endpoints ，它在Google I / O上被宣布为App Engine的受信任测试程序功能，现在每个人都可以使用它。借助端点，您可以注释简单的Java（或Python）类和方法来描述您的API。例如，这是一个简单的类，用于从井字游戏中获取和检索高分列表：

  @Api （name =tictactoe）
 public class ScoreEndpoint {
 @ApiMethod（name =scores.get）
 public Sc​​ore get（@Named（id）String id）{
 PersistenceManager pm = getPersistenceManager（）; 
分数分数= pm.getObjectById（Score.class，id）; 
 pm.close（）; 
的回报分数; 
} 
 
 @ApiMethod（name =scores.list）
 public List< Score> list（）{
 PersistenceManager pm = getPersistenceManager（）; 
 Query query = pm.newQuery（Score.class）; 
 return（List< Score>）pm.newQuery（query）.execute（）; 
 
 
 $ / code $ / pre 
 $ b 
特征
 
 
 
 
 
 支持Java和Python运行时
  
 
 基于Google API基础架构与许多用于Google自己的API的相同工具和库一起工作，例如 API Explorer 和 API控制台 
 
 
 自动生成的静态类型适用于Android和iOS的客户端库  - 这些库使用与Google相同的 Java 和 Objective-C 库用于访问其他Google提供的API，例如Calendar API   
 
 动态类型的JS客户端库  - 同样，用于访问JS中由Google提供的其他API的相同库
 
 
 内置对OAuth 2的支持
  
 
 与Google Plugin for Eclipse集成  - 这允许您自动创建基于模型的API或App Engine应用程序来备份现有的Android应用程序
 
 
 支持本地开发  - 您可以使用App Engine开发环境构建和测试您的API，就像其他App Engine功能一样

I am working on a project that involves mobile and web clients with Google's AppEngine PAAS. I would like to use RESTFul webservices with my AppEngine app.

I have looked over Stackoverflow for references to RESTFul service frameworks that can be used with AppEngine for both web (GWT) and mobile (Android) clients. Although Restlet seems to provide editions for AppEngine, GWT and Android, so far I've got it down to RestEasy mostly due to this question. 

There have been questions previously that discuss RESTFul frameworks but I don't think the comparisons apply well to this, now quite common, case. It would be helpful to hear experienced developers' views on the frameworks available for this set of platforms and merits versus demerits of each.
解决方案
You might wish to consider using Google Cloud Endpoints, which was announced as a trusted tester feature for App Engine at Google I/O, and is now available to everyone. With Endpoints, you annotate simple Java (or Python) classes and methods to describe your API. For example, this is a simple class to get and retrieve a list of high scores from a Tic Tac Toe game:
@Api(name = "tictactoe")
public class ScoreEndpoint {
  @ApiMethod(name = "scores.get")
  public Score get(@Named("id") String id) {
    PersistenceManager pm = getPersistenceManager();
    Score score = pm.getObjectById(Score.class, id);
    pm.close();
    return score;
  }

  @ApiMethod(name = "scores.list")
  public List<Score> list() {
    PersistenceManager pm = getPersistenceManager();
    Query query = pm.newQuery(Score.class);
    return (List<Score>) pm.newQuery(query).execute();
  }
}


Features


Support for Java and Python runtimes
Built on Google's API infrastructure - it works with many of the same tools and libraries used for Google's own APIs, such as the APIs Explorer and APIs Console
Automatically-generated, statically-typed client libraries for Android and iOS - these libraries are using the same Google-authored Java and Objective-C libraries you would use to access other Google-provided APIs such as the Calendar API
Dynamically-typed JS client library - again, the same library you use to access other Google-provided APIs in JS
Built in support for OAuth 2
Integration with the Google Plugin for Eclipse - this allows you to automatically create an API based on a model, or an App Engine application to back an existing Android app
Support for local development - you can build and test your API using the App Engine development environment, just as with other App Engine features
