Question

即使提供的REST端点已启动并且有效，下面的代码也会返回异常。正确处理它，因为DEBUG提示符显示了GET请求的链接。无论提供的REST端点如何，它都在http.request行失败。这是通过点击Run＆＃39; MyScript＆＃39;来执行的。在intelliJ 14.1 ..这段代码有什么缺失吗？资料来源：github.com/jgritman/httpbuilder/wiki/GET-Examples

11：42：30.897 [main] DEBUG groovyx.net.http.HTTPBuilder - GET http://ajax.googleapis.com/ajax/services/search/web?v=1.0&q=Calvin+and+Hobbes

Caught: java.net.UnknownHostException: ajax.googleapis.com

MyScript.groovy

import groovyx.net.http.ContentType
import groovyx.net.http.HTTPBuilder
import groovyx.net.http.RESTClient
import groovyx.net.http.Method

def http = new HTTPBuilder()

http.request( 'http://ajax.googleapis.com', Method.GET, ContentType.JSON ) { req ->
uri.path = '/ajax/services/search/web'
uri.query = [ v:'1.0', q: 'Calvin and Hobbes' ]
headers.'User-Agent' = "Mozilla/5.0 Firefox/3.0.4"
headers.Accept = 'application/json'

response.success = { resp, reader ->
    assert resp.statusLine.statusCode == 200
    println "Got response: ${resp.statusLine}"
    println "Content-Type: ${resp.headers.'Content-Type'}"
    println reader.text
}

    response.'404' = {
        println 'Not found'
    }
}

运行MyScript.groovy例外

REST客户端的groovy未知主机异常
