React Native如何用调用RestFul API

场景

利用React Native开发一个电商类的App,电商系统选择开源电子商城ECmall,ECmall移动端API利用UniConnector生成。调用前需要进行Token认证,认证通过可访问订单、发货单等。

第一步 安装React Native REST Client

npm install --save react-native-rest-client

第一步 在React Native应用中,创建ECmall RestFul Api实例,并继承RestClient class

import RestClient from ‘react-native-rest-client‘;

export default class ECmallRestApi extends RestClient {
  constructor () {
    // 初始化base URL,由于API是UniConnector自动生成,填写UniConnector网关地址
    super(‘http://d.uniconnector.com‘);
  }
};

第二步 设置调用Ecmall RestFul Api的Token

import RestClient from ‘react-native-rest-client‘;

export default class ECmallRestApi extends RestClient {
  constructor () {
    //初始化base URL,由于API是UniConnector自动生成,填写UniConnector网关地址
    super(‘http://d.uniconnector.com‘, {
      headers: {
        //X-UniConnector-Api-Key为UniConnector授权Key名称,d3a124f1-bd1f-1ea0-aac0-2b658e1dcxxx为申请授权的ApiKey
        X-UniConnector-Api-Key : ‘d3a124f1-bd1f-1ea0-aac0-2b658e1dcxxx‘
      }
    });
  }
};

第三步 调用ECmall的RestFul Api

import RestClient from ‘react-native-rest-client‘;

export default class ECmallRestApi extends RestClient {
  constructor () {
    //初始化base URL,由于API是UniConnector自动生成,填写UniConnector网关地址
    super(‘http://d.uniconnector.com‘, {
      headers: {
        //X-UniConnector-Api-Key为UniConnector授权Key名称,d3a124f1-bd1f-1ea0-aac0-2b658e1dcxxx为申请授权的ApiKey
        X-UniConnector-Api-Key : ‘d3a124f1-bd1f-1ea0-aac0-2b658e1dcxxx‘
      }
    });
  }

  // 获取订单信息
  getOrderById (orderId) {
    // 根据OrderId查询订单信息
    return this.GET(‘/ecm_order‘, { orderId });
  }

  //获取指定商铺的商品信息
  getStoreGoods (storeId) {
    // 根据商铺Id,查询商铺下所有的商品
    return this.GET(‘/ecm_goods‘, { storeId });
  }

  //发布一个商品
  publishGood(storeId, goodsName, description, price, ...) {
    return this.POST(‘/ecm_order‘, { storeId, goodsName, description, price, ...});
  }
};
