从 Google Cloud Endpoint 开始,tic tac toe 示例(请参阅https://github.com/GoogleCloudPlatform/appengine-endpoints-tictactoe-java

然后,在最新的 Android Ellipse 插件中通过 Ellipse 创建一个“AppEngine Connected Android Project”(参见https://developers.google.com/eclipse/docs/endpoints-androidconnected-gae

现在这会创建没有身份验证的端点。

// @Api(name = "messageEndpoint")
//NO AUTHENTICATION; OPEN ENDPOINT!

现在尝试使用 tic tac toe 应用程序作为示例添加身份验证。

@Api(name = "messageEndpoint",
version = "v1",
clientIds = {Ids.WEB_CLIENT_ID, Ids.ANDROID_CLIENT_ID, Ids.IOS_CLIENT_ID, com.google.api.server.spi.Constant.API_EXPLORER_CLIENT_ID},
audiences = {Ids.ANDROID_AUDIENCE}

)

如果出现 oauth 异常,请添加以下内容:

//public void sendMessage(@Named("message") String message)
  //throws IOException {

public void sendMessage(@Named("message") String message)
  throws OAuthRequestException,IOException {

并使用 api explorer https://[your-app-id].appspot.com/_ah/api/explorer 进行测试,我将 [your-app-id] 替换为我的特定应用程序 ID。

我的问题是为什么井字游戏示例有标题:“www-authenticate: GoogleLogin realm="https://www.google.com/accounts/ClientLogin", service="xapi" 和

一般来说,我们如何向“App Engine Connected Android Project”生成的端点添加身份验证?

从 web 应用程序、android 客户端或 iOS 客户端,我们可以从 api explorer 测试它吗?

“一般来说,我们如何向“App Engine Connected Android Project”生成的端点添加身份验证?”

这样做的说明在这里:
https ://developers.google.com/appengine/docs/java/endpoints/consume_android#making-authenticated-calls

您还将在此处(在后续页面上)看到有关 iOS 和 Javascript 的说明。

在服务器端,您需要将 User 对象添加为端点方法的第一个参数。

我不知道你其他问题的答案。
