vue的搭建项目

请求的封装，先在src下面创建一个utils的文件夹，文件夹里面有ajax.js loading.js index.js to

1 请求的封装 ajax文件 需要引入的文件在后面

/*

const done = function(h){
    return this.then(h).catch(({ code, msg }) => {
        console.error('請求出錯啦 =>', code, msg)
    })
}

　　toast文件

 */
const toast = (t, fn) => {
    if (window.toast){

    const tip = document.createElement('div')
    tip.className = 'ui-toast'
    tip.innerHTML = `<p>${ t }</p>`
    document.body.appendChild(tip)
    setTimeout(() => tip.classList.add('active'), 0)
    window.toast = tip

    setTimeout(() => {
        // if (!window.toast){
        //     return
        // }

        tip.classList.remove('active')
        setTimeout(() => {
            try {
                document.body.removeChild(tip)
            }
            catch(e){}
            finally {
                window.toast = null
            }

            fn && fn()
        }, 300)
    }, 1500)
}

export default toast

　　最后在main.js里面使用他

 前端获取Token，后台需要配置

Access-Control-Expose-Headers : 'Authorization'
response.setHeader("Cache-Control","no-store");
