如何为angular2上的GET请求设置全局超时

npm install @angular/http

import { NgModule } from '@angular/core';
import { HttpModule, Http } from '@angular/http';

@NgModule({
  imports: [HttpModule],
  providers: [Http]
})
export class AppModule { }

import { Http } from '@angular/http';

constructor(private http: Http) { }

import { RequestOptions, URLSearchParams } from '@angular/http';

const requestOptions = new RequestOptions();
requestOptions.timeout = 5000; // 设置超时时间为5秒

this.http.get('https://example.com/api/data', requestOptions)
  .subscribe(response => {
    // 处理响应数据
  }, error => {
    // 处理错误
  });
