【问题描述】:
我正在尝试构建一个接受 XML 的 REST 服务并将其转换为 JSON 并调用接受 JSON 的外部服务并将我的 JSON 放入其中。我可以把 json 放在没有漂亮的地方,但我想把 json 放在漂亮的格式中。请建议怎么做,下面是我的代码...
package com.mypackge
import grails.converters.JSON
import grails.rest.RestfulController
import grails.plugins.rest.client.RestBuilder
class RestCustomerController extends RestfulController {
/*
static responseFormats = ['json', 'xml']
RestCustomerController() {
super(Customer)
}
*/
def index() {
convertXmlToJson()
}
def myJson = ''
def convertXmlToJson() {
def xml = ''' <Customer>
<customerid>9999999999999</customerid>
<ssn>8888</ssn>
<taxid>8888</taxid>
<address>
<addressline1>Yamber Ln</addressline1>
<addressline1>8664 SE</addressline1>
<city>CCCCC</city>
<state>CC</state>
<zipcode>97679</zipcode>
</address>
<firstname>Scott</firstname>
<middlename></middlename>
<lastname>David</lastname>
<account>
<accountno>576-294738943</accountno>
<accounttype>Lease</accounttype>
<accountsubtype></accountsubtype>
<accountstatus>complete</accountstatus>
<firstname>Scott</firstname>
<middlename></middlename>
<lastname>David</lastname>
<businessname></businessname>
<billingsystem>yoiuhn</billingsystem>
<brand></brand>
<plantype></plantype>
<billingaddress>
<addressline1>Yamber Ln</addressline1>
<addressline1>8664 SE </addressline1>
<city>CCCCC</city>
<state>CC</state>
<zipcode>97679</zipcode>
</billingaddress>
<job>
<jobid>8276437463728</jobid>
<jobstatus>SUCCESS</jobstatus>
</job>
</account>
</Customer>
'''.stripMargin()
// Parse it
def parsed = new XmlParser().parseText( xml )
def myId = parsed.customerid.text()
// Deal with each node:
def handle
handle = { node ->
if( node instanceof String ) {
node
}
else {
[ (node.name()): node.collect( handle ) ]
}
}
// Convert it to a Map containing a List of Maps
def jsonObject = [ (parsed.name()): parsed.collect { node ->
[ (node.name()): node.collect( handle ) ]
} ]
def json = new groovy.json.JsonBuilder(jsonObject) //.toPrettyString()
// Check it's what we expected
def mmyresp
try{
mmyresp = putRequest(myId,json)
}catch(Exception e) {
mmyresp = 'Please Validate JSON ....'
}
}
def putRequest(String id, JSON myJson) {
String url = "http://foo.com/customer/external/"+id
def rest = new RestBuilder()
def resp = rest.put(url){
contentType "application/json"
json{
myJson
}
}
return resp
}
}
记录按以下格式添加...
{"Customer":[{"customerid":["9999999999999"]},{"ssn":["8888"]},
{"taxid":["8888"]},{"address":[{"addressline1":["Yamber Ln"]},
{"addressline1":["8664 SE"]},{"city":["CCCCC"]},{"state":["CC"]},{"zipcode":["97679"]}]},
{"firstname":["Scott"]},{"middlename":[]},{"lastname":["David"]},{"businessname":[]},
{"account":[{"accountno":["576-294738943"]},{"accounttype":["Lease"]},{"accountsubtype":[]},
{"accountstatus":["complete"]},{"firstname":["Scott"]},{"middlename":[]},{"lastname":["David"]},
{"businessname":[]},{"billingsystem":["yoiuhn"]},{"brand":[]},{"plantype":[]},
{"billingaddress":[{"addressline1":["Yamber Ln"]},{"addressline1":["8664 SE"]},
{"city":["CCCCC"]},{"state":["CC"]},{"zipcode":["97679"]}]},{"job":[{"jobid":["8276437463728"]},
,{"jobstatus":["SUCCESS"]}]}]}]}
但我希望它以漂亮的格式插入。我尝试了.toPrettyString(),但在尝试作为 json 放置时出现了强制转换异常。我是第一次尝试 REST 服务,不知道我在哪里做错了。请就此向我提出建议。
