我使用Grails 2.3.x创建了一个REST Web服务,如下所示:
import grails.rest.RestfulController
class CityController extends RestfulController{
static responseFormats = ['json', 'xml']
CityController() {
super(City)
}
}
这是我的域类:
import groovy.transform.ToString
import groovy.transform.EqualsAndHashCode
/**
* City
* A domain class describes the data object and it's mapping to the database
*/
@ToString(includeNames = true, includeFields = true, excludes = 'dateCreated,lastUpdated,metaClass')
@EqualsAndHashCode
class City {
/* Default (injected) attributes of GORM */
Long id
Long version
/* Automatic timestamping of GORM */
Date dateCreated
Date lastUpdated
String cityName
String postalCode
String countryCode // either iso2 or iso3
static constraints = {
postalCode blank:false, nullable:false
cityName blank:false, nullable:false
countryCode minSize:2, maxSize:3, blank:false, nullable:false, matches: "[A-Z]+"
}
}
这是urlMapping
class UrlMappings {
static mappings = {
"/$controller/$action?/$id?(.$format)?"{
constraints {
// apply constraints here
}
}
"/"(view:"/index")
"500"(view:'/error')
//
// RESTService api
"/api/city"(resources: 'city')
}
}
当我尝试使用curl获取数据时,我设法使用以下代码获取结果:
curl -X GET -H "Accept:application/json" http://localhost:8080/ComuneUtenti/city
但是,当我尝试将数据发布到WS时,出现以下错误:
curl: (6) Could not resolve host: countryCode
curl: (6) Could not resolve host: postalCode
curl: (3) [globbing] unmatched close brace/bracket in column 6
{"errors":[{"object":"comuneutenti.City","field":"postalCode","rejected-value":null,"message":"property [postalCode] of class [class comuneutenti.City] cannot be null"},{"object":"comuneutenti.City","field":"cityName","rejected-value":null,"message":"property
[cityName] of class [class comuneutenti.City] cannot be null"},{"object":"comuneutenti.City","field":"countryCode","rejected-value":null,"message":"property[countryCode] of class [class comuneutenti.City] cannot be null"}]}
这是我的帖子:
curl -H "Content-Type:application/json" -X POST -d '{"cityName":"NewYork", "countryCode":"IT", "postalCode": "00166"}' http://localhost:8080/ComuneUtenti/api/city
我想念什么?
我正在使用Grails 2.3.10
可以使用Postman调用相同的WS。
谢谢
最佳答案
您是否尝试过erichelgeson的建议?
正确的 curl 方法是
curl -H "Content-Type:application/json" -X POST -d '{"cityName":"NewYork", "countryCode":"IT", "postalCode": "00166"}' http://localhost:8080/ComuneUtenti/api/city
请注意JSON有效负载周围的单引号。
要查看实际情况,可以使用echo命令。
$ echo {"hello":"world"}
{hello:world}
$ echo '{"hello":"world"}'
{"hello":"world"}
