如何将漂亮的JSON放入REST api

Question

我试图建立它接受一个REST服务XML并将其转换成JSON并调用它接受外部的服务JSON,把我JSON进去.我能够把json放得很漂亮,但是我想以漂亮的格式把json放进去.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>

                                                            <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
    }

}

记录以下面的格式添加......

{"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"]}]}]}]}

但我希望以漂亮的格式插入.我试过.toPrettyString()但是当试图把它作为json时得到了铸造异常.我是第一次尝试REST服务,不知道我做错了什么.请建议我这个.

您应该在中设置以下字段Config.groovy.

grails.converters.default.pretty.print = true

这将为xml和json打印.

您可以选择将其设置为xml或json,如下所示:

对于json:

grails.converters.json.pretty.print = true

对于xml

grails.converters.xml.pretty.print = true

Config.groovy参赛样本是:

environments {
    development {
        grails.converters.json.pretty.print = true 
    }
 } 

希望能帮助到你!!!
