Merhaba Bir grants huzurlu bir kod var. Bir Json alma ve silme isteğini mükemmel yaparım. Benim sorunum: json ile bir Put veya post isteği yapmak istiyorum ama bunu yapmak için bir program kullanırsam, bir hata vardır ve bunu yapamam! İşte benim kod : Bir sınıfı:POST/PUT Json RESTful isteği ile ilgili sorunlar Grails
package catalogo.json
class Catalogo {
String nombre
String descripcion
String url
Set <Parametros>parametros =[]
static hasMany = [parametros:Parametros]
int numeroParametros = parametros.size()
}
Diğeri sınıfı:
package catalogo.json
class Parametros {
String tipoParametro
String json
static constraints = {
tipoParametro(nullable:true)
json(nullable:true)
}
}
Ben istekte benim json koymak nasıl bilmiyorum. Onu koyduğumda hata yapar.
Örnek:
I POST talebi PUT. Burada gövde application/json
(veya text/json
aynı hatadır) Karakter Kümesi-utf-8
{"descripcion": "bla", "nombre" : "lalala", "numeroParametros":3, "parametros":[{
"tipoParametro":"string", "json":"bla"}],"url":"http://www.google.com"}
Ve hatası:
