我想用axios发送一个post请求到我的web服务器。我有一个客户端,它接受用户输入来填充一个字符串数组,然后用axios发送一个post请求,由服务器处理:
if (parsedInput > 0 && parsedInput <= 8) {
let listOfNames = [];
for (let i=0; i<parsedInput; i++) {
let name = await rl.question(`Enter name #${i}\n`);
listOfNames.push(name);
console.log(`Added ${name} to list of players\n`);
}
axios.post('http://localhost:3000/start', {
names: listOfNames,
})
.then(function (response) {
console.log(response);
})
.catch(function (error) {
console.log(error);
});
}
我的服务器虽然还没有处理请求,只是应该打印出来,它收到了来自客户端的请求:
const express = require('express');
const app = express()
const port = 3000
var listOfNames = [];
app.post('/start', async (req, res) => {
listOfNames = req.body.names;
console.log(listOfNames);
res.status(200).send("Names added");
});
app.get('/', function(req, res, next) {
res.send("Welcome to the homepage of bowling");
})
app.listen(port, () => {
console.log('Listening to request on port 3000');
});
就在我发送名称数组时,我收到了这个ECONNRESET错误。

很抱歉的文本转储,不知道是否有任何有用的信息在JSON对象。我的服务器从来没有结束打印的名字列表,所以我假设它从来没有真正得到后请求。我该如何修复这个ECONNRESET错误。

根据您的Express版本,您可能需要在处理程序之前使用
bodyParser
