使用 REST 删除 http [英] http delete with REST

问题描述

我目前正在使用 Jersey 框架(JAX-RS 实现)来构建 RESTful Web 服务.项目中的资源类已经实现了标准的 HTTP 操作——GET,POST &删除.我试图弄清楚如何将请求参数从客户端发送到这些方法.

I am currently using Jersey Framework (JAX-RS implementation) for building RESTful Web Services. The Resource classes in the project have implemented the standard HTTP operations - GET,POST & DELETE. I am trying to figure out how to send request parameters from client to these methods.

对于 GET 它将在查询字符串中(使用 @QueryParam 提取)，POST 将是名称/值对列表(使用 @FormParam 提取)发送请求正文.我使用 HTTPClient 对它们进行了测试并且工作正常.对于 DELETE 操作，我没有找到关于参数类型/格式的任何结论性答案.DELETE 操作是否接收查询字符串中的参数(使用 @QueryParam 提取)或正文中(使用 @FormParam 提取)?

For GET it would be in the query string(extract using @QueryParam) and POST would be name/value pair list (extract using @FormParam) sent in with the request body. I tested them using HTTPClient and worked fine. For DELETE operation, I am not finding any conclusive answers on the parameter type/format. Does DELETE operation receive parameters in the query string(extract using @QueryParam) or in the body(extract using @FormParam)?

在网络上的大多数 DELETE 示例中，我观察到使用 @PathParam 注释进行参数提取(这将再次来自查询字符串).

In most DELETE examples on the web, I observe the use of @PathParam annotation for parameter extraction(this would be from the query string again).

这是将参数传递给 DELETE 方法的正确方法吗?我只是想在这里小心一点，以免违反任何 REST 原则.

Is this the correct way of passing parameters to the DELETE method? I just want to be careful here so that I am not violating any REST principles.

推荐答案

是的，这取决于你，但是当我了解 REST 思想时，DELETE URL 应该删除 GET URL 请求返​​回的内容.例如，如果

Yes, its up to you, but as I get REST ideology, DELETE URL should delete something that is returned by a GET URL request. For example, if

GET http://server/app/item/45678

返回 id 为 45678 的项目，

returns item with id 45678,

DELETE http://server/app/item/45678

应该删除它.

因此，我认为使用 PathParam 比使用 QueryParam 更好，因为 QueryParam 可以用于控制工作的某些方面.

Thus, I think it is better to use PathParam than QueryParam, when QueryParam can be used to control some aspects of work.

DELETE http://server/app/item/45678?wipeData=true
