封装fecth请求

import 'whatwg-fetch';

export function fetchData(endpoint) {
    let myHeader = {
        headers: {
            "Authorisation": sessionStorage.getItem('openid'),
            "Accept"       : 'application/json',
            'Content-Type' : 'application/json'
        },
        method : 'GET',
    };
    return fetch(endpoint, myHeader)
        .then(res=> {
            return res.json()
        })
        .catch(e=> {
            console.log(e.message)
        })
}
export function postData(endpoint, method = 'post', body = {}) {
    let methods  = ['GET', 'POST', 'DELETE', 'PUT'];
    let myHeader = {
        headers: {
            "Authorisation": sessionStorage.getItem('openid'),
            "Accept"       : 'application/json',
            'Content-Type' : 'application/json'
        },
        method : methods[methods.indexOf(method.toUpperCase())],
        body   : body
    };
    return fetch(endpoint, myHeader)
        .then(res => {
            return res.json()
        })
        .catch(e => {
            console.log(e.message)
        })
}
export function obj_to_query(path = '/', obj) {
    let parts = [];
    for (let key in obj) {
        if (obj.hasOwnProperty(key)) {
            parts.push(encodeURIComponent(key) + '=' + encodeURIComponent(obj[key]));
        }
    }
    return path + "?" + parts.join('&');
}

使用get请求

export function fetchStockData(total, timeRange=''){
    return (dispatch, getState)=>{
        const club = getState().getClub.club;
        return fetchData(obj_to_query(URL + "/",{
            m   : 'Home',
            c   : 'Bosspage',
            a   : 'getCommodityList',
            club: club,
            total_c:total,
            timeRange:timeRange
        })).then(data=>{
            dispatch(setAddCommodity(data));
            dispatch(setMiddleData(data));
        })
    }
}
使用post请求

export function fetchProcurement(club,name,commodity,number,primeCost,url=''){
    return(dispatch,getState)=>{
        return postData(obj_to_query(URL + "/",{
            m   : 'Home',
            c   : 'Bosspage',
            a   : 'procurement',
        }),'post',JSON.stringify({
            club:club,
            name:name,
            commodity_id:commodity,
            number:number,
            primeCost:primeCost,
            document_url:url,
        }))
            .then(res=>{
                console.log('res',res);
                if(res.status == '0001'){
                    alert('入库成功')
                }else {
                    alert('商品库存写入失败')
                }
            })
            .catch(()=>alert('入库失败'))
    }
}
