可以用axios.all 一次性发起多个接口请求

 

    function r1() {
        return axios.get(url1)
    }
    function r2() {
        return axios.get(url2)
    }
    function r3() {
        return axios.get(url3)
    }
    await axios.all([r1(),r2(),r3()]).then(axios.spread((r1,r2,r3)=>{
        article = r1.data
        taglist = r2.data
        hot_article = r3.data
    }))
