Question

我想发送JSON请求

   for (let i = 0; i < this.myLaptopNamesList.length; i++) {
  alert(""+i);
  let LaptopMake1 = 'LaptopMake'+i;
  let LaptopSerial1='LaptopSerial'+i;
  alert(""+LaptopMake1+""+LaptopSerial1)
  alert(""+this.myLaptopNamesList[i].name+""+this.myLaptopNamesList[i].number)
 let  customLaptop: {};

  customLaptop = {
    LaptopMake1: this.myLaptopNamesList[i].name,
    LaptopSerial1: this.myLaptopNamesList[i].number
  };
  this.newCusomLaptop = customLaptop;
}

我从我的for循环获得了laptopMake和LaptopSerial。我该如何发送请求？

Answer 1

您需要使用Http

中的@angular/http

import { Injectable } from '@angular/core';
import { Http, Response } from '@angular/http';
import { Observable } from 'rxjs/Observable';
import 'rxjs/Rx';

@Injectable()
export class AppProvider {
constructor(private http: Http) {}

public postRequest(customLaptop: any):Observable<SearchCriteriaObject> {
    let url:string = 'url you want to post to';

    return this.http.post(url, customLaptop)
      .map((res:Response) => res.json());
  }
}

在你的component.ts中你可以调用这个方法并订阅响应。

import { AppProvider } from 'location of app provider';

export class Component {
    constructor(private provider: AppProvider){}

    this.provider.postRequest(this.customLaptop)
        .subscribe((data: any) => {
            // do something on success
        }, (error: any) => {
            // do something on error
        })
}
