Question

在我的网址映射中，我定义了此映射：

"/$controller/$action?/$id?(.$format)?"{}

现在我要添加一组版本2服务。

例如： URI上的一项新服务：/api/myaction

并且我希望能够定义一个新端点/api/v2/myaction，其中 myaction 将映射到一个名为 myactionV2

的新动作。

有许多方法可以做到这一点，而最佳解决方案取决于您未包括在问题中的某些因素。这是最贴近问题和OP上面添加的注释的解决方案。

package demo.v1

class ApiController {
    static namespace = 'v1'

    def myaction() {
        render 'This request was handled by version 1 of the api'
    }
}

package demo.v2

class ApiController {
    static namespace = 'v2'

    def myaction() {
        render 'This request was handled by version 2 of the api'
    }
}

package demo.v3

class ApiController {
    static namespace = 'v3'

    def myaction() {
        render 'This request was handled by version 3 of the api'
    }
}

package javaheadendpoints

class UrlMappings {

    static mappings = {
        "/$controller/$action?/$id?(.$format)?"{
            constraints {
                // apply constraints here
            }
        }

        "/$controller/$namespace/$action/$id?(.$format)?" {
            // ...
        }

        "/"(view:"/index")
        "500"(view:'/error')
        "404"(view:'/notFound')
    }
}

发送请求会产生我认为的请求行为：

$ curl http://localhost:8080/api/v1/myaction
This request was handled by version 1 of the api
$ curl http://localhost:8080/api/v2/myaction
This request was handled by version 2 of the api
$ curl http://localhost:8080/api/v3/myaction
This request was handled by version 3 of the api

其他选项包括使用Version http标头，但是由于上面的某些措辞，我认为这并不是您想要的。

我希望有帮助。

Answer 2

不应该那样做，我建议的方法是分成两个控制器

/api1/myaction

/api2/myaction

或正在行动

/api/myaction1

/api/myaction2
