Question

我请求Google Places API，并希望以XML格式获取响应。我这样做：

def http = new HttpURLClient( )
def resp = http.request(url:uRL)
render(text: resp.getData(), encoding:"UTF-8", contentType:"text/xml")

它返回数据，但没有XML标记。所以普通数据为字符串。我100％肯定，我从Google获得了XML格式的数据。谷歌的回复看起来像（这显示了浏览器）：

<PlaceSearchResponse>
<status>OK</status>
<result>
<name>Beth-El Synagogue</name>

我只是想再次呈现回复。那么，顶部的代码有什么问题？ THX。

Answer 1

首先将XML解析为文本：

import groovy.xml.XmlUtil
....
def http = new HttpURLClient( )
def resp = http.request(url:uRL)
def xmlAsText = XmlUtil.serialize(resp.data)
render(text: xmlAsText, encoding:"UTF-8", contentType:"text/xml")

Grails渲染XML丢失xml格式和标签
