nodeJS中如何用async,await获取并操作request返回值?

let router = new Router();
router.get('/info', async(ctx) => {
    let result = await request.get('http://api/xxxx');
    ctx.body = result;
});

这样是可以在/info页面上获取到request返回值的,但是如何对其内部进行操作?我使用console.log(result.xxx)输出都是undifined(假设api返回的是json)


刚出去吃饭去了···

const apireq = url => new Promise((resolve, reject) => request.get(url, (err, response, body) => {
    if (err) {
    reject(err);
    } else {
    resolve(body);
    }
}));

现在貌似支持promise了,不用额外引入@熊丸子...

var Promise = require('Promise');

function callApi(){
    return new Promise(function(resolve,reject){
        setTimeout(function () {
            resolve("aaa");
        }, 2000);
    });
}

async function runAsync(){
    let myVal = await callApi();
    console.log(myVal);
}


runAsync();

我写了一段你可以参考下。
