Grails 2.4.3：使用REST服务 [英] Grails 2.4.3: Consume a REST Service

问题描述

如何在Grails 2.4.3中使用RESTful Web服务。我也需要使用基本身份验证。

你会认为这个问题已经很好的回答了，但我真的很努力地找到一个。许多答案都指向了Grails休息插件的方向，我尝试过，但无法为我工作。我认为我可能只是在努力处理文档并将其用于错误。

解决方案

//grails.org/plugin/rest-client-builderrel =noreferrer> REST客户端生成器插件，它的记录效果更好，对我来说效果更好。感谢Graeme Rocher！这里有一个简单的例子，希望对其他人有帮助。

  import grails.plugins.rest.client.RestBuilder 
 import grails.transaction.Transactional 
 
 @Transactional 
 class BatchInstanceService {
 
 def getBatch（String id）{
 String url =https：// foo.com/batch/$id
 
 def resp = new RestBuilder（）。get（url）{
 header'Authorization'，'Basic base64EncodedUsername& Password'
} 
 
 
  

这里是测试类。

  import grails.test.mixin。* 
 
 import org.apache.commons.httpclient。* 
 import org.apache.commons.httpclient.methods。* 
 import org.springframework.http.HttpStatus 
 
 import spock.lang.Specification 
 
 @TestFor（BatchInstanceService） 
 class BatchInstanceServiceSpec extends Specification {
 
 voidtest get batch（）{
 when：
 def resp = service.restart（'BI1234'）
 
 then：
 resp.status == HttpStatus.OK.value 
} 
} 
  

返回的对象 resp ，是 ResponseEntity 课程。

我真的希望这有助于。如果有更好的例子，请发布链接。谢谢！

How do I consume a RESTful web service in Grails 2.4.3. I also need to use Basic Authentication.

You would think there would be an good answer to this question already, but I have really struggled to find one. Many answers point me in the direction of the Grails rest plugin, which I have tried but could not get to work for me. I think I am probably just struggling with the docs and using it wrong.

解决方案

I found the REST Client Builder Plugin, which was better documented and worked much better for me. Thanks to Graeme Rocher for that! Here's a simple example that will hopefully be helpful to others.

import grails.plugins.rest.client.RestBuilder
import grails.transaction.Transactional

@Transactional
class BatchInstanceService {

    def getBatch(String id) {
        String url = "https://foo.com/batch/$id"

        def resp = new RestBuilder().get(url) {
            header 'Authorization', 'Basic base64EncodedUsername&Password'
        }
    }
}

And here's the test class.

import grails.test.mixin.*

import org.apache.commons.httpclient.*
import org.apache.commons.httpclient.methods.*
import org.springframework.http.HttpStatus

import spock.lang.Specification

@TestFor(BatchInstanceService)
class BatchInstanceServiceSpec extends Specification {

    void "test get batch" () {
        when:
        def resp = service.restart('BI1234')

        then:
        resp.status == HttpStatus.OK.value
    }
}

The object returned, resp, is an instance of the ResponseEntity class.

I really hope this helps. If there are better examples please post links to them. Thanks!
