问题描述
我已经在Eclipse中使用 生成的服务有一个名为DeviceInfoEndpoint的生成端点。代码如下所示以及web.xml中的代码。假设我在本地托管端口8888,应该访问哪个URL listDeviceInfo()?我尝试了以下方法: 获取DeviceInfoEndpoint.java: Web.xml: API请求路径通常应符合以下要求: 如果您有兴趣获取/更新/删除特定资源,请将ID添加到末尾。在你的例子中,这表明你应该查询: (当您映射到 通常,APIs Explorer位于 I've generated a Google Endpoint AppEngine project in Eclipse by using the The service generated has one generated endpoint called DeviceInfoEndpoint. The code is shown below as well as the code in web.xml. Which URL should I access listDeviceInfo() with given that I'm hosting on port 8888 locally? I've tried the following: Exerpt of DeviceInfoEndpoint.java: Web.xml: API request paths should generally conform to the following: If you're interested in fetching/updating/deleting a specific resource, add an ID to the end. In your example, that suggests you should be querying: (which maps to In general, the APIs Explorer available at 这篇关于访问Hello-World Google云端点服务的URL是什么?的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持!

生成了一个Google Endpoint AppEngine项目,如。然而,那篇文章并未描述 ,官方的Google文档也描述得不好,哪个URL可以在本地访问该服务?
