Grails REST with @Resource - PUT没有更新 [英] Grails REST with @Resource - PUT is not updating

问题描述

我现在正在学习grails（2.4.0），并且自动生成REST方法有一个奇怪的问题。所以，我有一个简单的域

p>

  @Resource（uri ='/ unit'，formats = ['json']）
 class Unit {
字符串名称; 
} 
  

我可以使用GET / POST / DELETE方法成功列出/创建/删除实例，但PUT方法什么都不做：

  curl -i -X PUT -HContent-Type：application / json-d '{name：fail，id：65}'localhost：8080 / app / unit / 65 
 HTTP / 1.1 200 OK 
服务器：Apache-Coyote / 1.1 
位置：http：// localhost：8080 / app / unit / 65 
内容类型：application / json; charset = UTF-8 
传输编码：分块
日期：Sun，01 Jun 2014 09:25:02 GMT 
 
 {class：app.Unit，id：65，name：test} 
  

后续的GET请求也会返回name：test而不是name：fail

我可以做错了吗？

解决方案

这是一个只涉及更新（而不是新创建的实例）的错误。我已经完成了修复，我们将在2.4.1中包含此修复程序。请参阅 https://jira.grails.org/browse/GRAILS-11462 。 p>

缺点是即使请求有一个正文，请求参数也会进行更新。解决方法是更改​​，以便更新完成时，如果请求具有正文，则使用正文，如果不正确，则使用请求参数。

对不起，感谢您的输入。

I'm learning grails (2.4.0) right now and have a weird problem with automatically generated REST methods.

So, i have a simple domain

@Resource(uri = '/unit', formats = ['json'])
class Unit {
    String name;
}

I can successfully list/create/delete instances with GET/POST/DELETE methods, but PUT method does nothing:

curl -i -X PUT -H "Content-Type: application/json" -d '{"name":"fail", "id":65}' localhost:8080/app/unit/65
HTTP/1.1 200 OK
Server: Apache-Coyote/1.1
Location: http://localhost:8080/app/unit/65
Content-Type: application/json;charset=UTF-8
Transfer-Encoding: chunked
Date: Sun, 01 Jun 2014 09:25:02 GMT

{"class":"app.Unit","id":65,"name":"test"}

subsequent GET requests will also return name:test instead of name:fail

What i can be doing wrong?

解决方案

This is a bug which only relates to updates (not to newly created instances). I have worked up the fix and we will have this fix included in 2.4.1. See https://jira.grails.org/browse/GRAILS-11462.

The short of it is that updates are being done with the request parameters, even if the request has a body. The fix is to change that so when the update is done, if the request has a body then the body is used and if it does not, the request a parameters are used.

Sorry for the trouble and thanks for the input.
