从rc-1升级到rc-3后,JSON.stringfy()
方法会在每个值的开头和结尾返回\
的值:
{
\"perfil\":\"CLIENTE\", ...
}
我该如何解决这个问题?
代码段:
post(url, data) {
console.log(JSON.stringify(data));
return Observable.create(observer =>
this.http.post(this.restConfig.baseUrl + url, JSON.stringify(data), {
headers: this.getDefaultHeaders()
}).subscribe(
data => this.next(observer, data)
, err => {
console.log(err);
if (err.status === 401) {
this.redirectAuth();
}
observer.error(err);
}
)
);
}
我的Java RESTful服务无法解析输出:
Unexpected token (VALUE_STRING), expected FIELD_NAME: missing property 'perfil' that is to contain type id (for class br.com.inbit.medipop.model.entities.impl.Cliente) at [Source: java.io.ByteArrayInputStream@79f844cf; line: 1, column: 1]

})
public abstract class Usuario {
@NotNull

@Column(insertable = false, updatable = false)

...
}
stringfy
之前的数据:
{"perfil":"CLIENTE","pessoa":{"tipo":"FISICA","sexo":"MASCULINO","nome":"Marcos Kichel","cpf":"911.111.064-36","rg":"1234"},"dependentes":[],"email":"anackichel@gmail.com"}

您似乎正在对已经字符串化的内容进行字符串化。取出JSON.stringify(),你应该好好去。

此处的问题实际上并非由转义引号引起,而是perfil
字段的错误数据类型。在您的Java代码中,它应该是一个对象,而在json中,您传递String值"CLIENTE"
。
因此,要么确保在" perfil"内发送一个对象。字段或将perfil
字段的类型从PerfilUsuario
更改为字符串
