Express中的res.redirect有问题

我一直在尝试从搜索表单中输入我的位置，它会登录到控制台，但是res.redirect不会将我带到新的URL。 （给出的URL仅是示例）

const express = require('express');
const cors = require('cors');

// Utils
const geocode = require('./utils/geocode');
const forecast = require('./utils/weatherstack');

const app = express();

app.use(express.json());
app.use(express.urlencoded({ extended: false }));
app.use(cors())

let location;

app.post('/search-location', async (req,res) => {
    try {
        location = await req.body.location
        return res.redirect('')
    } catch (e) {
        res.status(500).send(e)
    }    
})

app.listen(9000, () => {
  console.log("server is up and running on 9000");
})

我精简了您的代码，以下代码段为我提供了正确的重定向：

const express = require('express');

const app = express();

app.post('/search-location', async (req,res) => {
    try {
        return res.redirect('https://www.google')
    } catch (e) {
        res.status(500).send(e)
    }    
})

app.listen(9000, () => {
  console.log("server is up and running on 9000");
})

curl -X POST localhost:9000/search-location

您的问题很可能是location = await req.body.location，因为req.body.location不是一个承诺（只是客户端解析的POST正文对象，无法等待它。

也许您打算将其包装在函数中：

location = await computeFunction(req.body.location)
