首先封装get:(get.js)

import 'whatwg-fetch'
import 'es6-promise'

export function get(url) {
	// var result = fetch('http://www.mockhttp.cn'+url, { //打包apk时候使用
	var result = fetch(''+url, {
		credentails: 'include',
		mode: "cors",
		headers: {
			'Accept': 'application/json, text/plain, */*',
			'Content-Type': 'application/x-www-form-urlencoded'
		}
	});
	return result;
}
封装post:(post.js)

import 'whatwg-fetch'
import 'es6-promise'

//将json对象拼接成 key=val&key=val 的字符串形式
function obj2params(obj) {
	var result = '';
	var item;
	for(item in obj){
		result += '&' + item + '=' +encodeURIComponent(obj[item]);
	}

	if(result) {
		result = result.slice(1);
	}
	return result;
}

//发送 post 请求(首先会发送option)
export function post(url, paramsObj) {
	var result = fetch(url, {
		method: 'post',
		mode:'cors',
		headers: {
			'Accept': 'application/json',
			'Content-Type': 'application/x-www-form-urlencoded'
		},
		body: obj2params(paramsObj)
	});

	return result;
}
引用:(对外提供出口index.js)

import { get } from '../get'
import { post } from '../post'

export function postGpio(param) {
    const result = post('*******',param)
    return result
}
在jsx中调用:(写了一个函数 调用就行)

postMessage(param) {
        //send message
        var params = {}
        params.whichGpio = param
        const result = postGpio(params)
        result.then(res => {
            return res.json()
        }).then(json => {
            // get result
            const data = json
            if(data.code == '1'){
                Toast.success('Send success !', 2);
            }
        }).catch(ex => {
            // 发生错误
            console.error('获取数据出错, ', ex.message)
        })
    }
