无法在数字'1'上创建属性'route'

Question

使用 RestAPI，我尝试通过这些简单的代码从数据库中删除一条记录。

import { Component } from '@angular/core';
import { RestangularModule, Restangular } from 'ngx-restangular'; 
import { HomePage } from '../pages/home/home';
@Component({
templateUrl: 'app.html'
})
export class MyApp {
rootPage:any = HomePage;
constructor(private restangular: Restangular) {
this.restangular.one('v1/my_products', '5b3621ce1dbaba5598cdbe08')
.get()
.subscribe((res: any) => {
res.data.remove();
})
}
}

奇怪的是，文档已成功删除，但我总是收到以下错误，并且我的应用程序已关闭

与 ngx-restangular@1.0.13 - 3.0.0 的情况相同

怎么了？

Answer 1

我不知道这是否是最好的解决方案。但是，我刚刚找到了解决此问题的解决方案。

RestangularProvider.addResponseInterceptor((data, operation, what, url, response) => 
{
switch (operation) {
case 'post':
case 'put':
case 'remove':
if (!data)
return {};
default: {
if (typeof data === 'number') { return {} }
if (typeof data === 'object') { return data }
}
}
});

Answer 2

向@jlcj致敬

这是@jlcj答案的延伸，也是我迄今为止找到的最佳解决方案。

我的应用程序正在运行 ngx-restangular v5.0.0

Restangular 需要一个对象作为后端服务器的响应。因此，如果您希望从后端服务器返回一个数字，则必须将数据包装在大括号 { data } 中作为对象。否则，将出现错误"无法在编号 1 上创建属性路由"。

RestangularProvider.addResponseInterceptor((data, operation, what, url, response) =>
{
switch (operation) {
case 'post':      
case 'put':
case 'remove':
if (!data)
return {};
default: {
if (typeof data === 'number') { return { data } }
if (typeof data === 'object') { return data }
}
}
});
