javascript - 异步/等待永远卡住

Question

编写一个使用 async/await 的 web 应用程序，但卡在 var r1 = await fetch(url).then((r) => r.text()) 行似乎正在处理的位置永远。我在端口 80 上监听的 Web 服务器甚至没有收到请求。

const fetch = require ('fetch-node')
const express = require('express');
const app = express();

var savedResolve;

app.listen(8079, '127.0.0.1', function() {
    console.log('listening on 8079')
})
app.get('/*', async function (req, res) {
    console.log(req.path)
    res.setHeader('Content-Type', 'text/html');
    await task()
    res.send('Done')
})


async function task() {
    console.log("starting..")
    var url = "http://localhost/prod/te.php";
    var r1 = await fetch(url).then((r) => r.text())
    console.log(r1)
    return "done"
}

有什么想法吗？提前致谢!

感谢@deryck 的建议，在 fetch 调用行附近添加 try 和 catch，得到以下错误

node-fetch和 fetch-node是两个不同的库。

根据显示的代码，node-fetch 是应该使用的库。
