ES6 从入门到精通 # 17：Promise 的基本使用

 let pro = new Promise((resolved, rejected) => {
 })
 console.log(pro)

let pro = new Promise((resolved, rejected) => {
    let res = {
        code: 200,
        desc: "处理成功",
        data: {
            name: "kaimo"
        }
    }
    setTimeout(() => {
        if(res.code === 200) {
            resolved(res.data);
        } else {
            rejected(res.desc);
        }
    }, 1000)
})
pro.then(val => {
    console.log(val)
}, err => {
    console.log(err)
})

let pro = new Promise((resolved, rejected) => {
    let res = {
        code: 500,
        desc: "服务器内部异常",
    }
    setTimeout(() => {
        if(res.code === 200) {
            resolved(res.data);
        } else {
            rejected(res.desc);
        }
    }, 1000)
})
pro.then(val => {
    console.log(val)
}, err => {
    console.log(err)
})

function getData(ms) {
    return new Promise((resolved, rejected) => {
        setTimeout(() => {
            resolved("如果你追到我，我就让你嘿嘿嘿");
        }, ms)
    })
}
getData(1000).then(res => {
    console.log(res)
})
