Question

我使用Node.js时遇到问题我通过GET请求将数据发送到特殊脚本，该脚本应读取此数据并将其写入MySQL。以下是GET请求的示例（很长）：

我做了很少的实验，我发现它在PHP中工作正常，我的代码（仅用于输出）：

<?php
echo $_GET["bssid"]." ".$_GET["mac"]." ".$_GET["rssi"]." ".$_GET["hotspots_list"];
 ?>

但不在Node.js中！这是我的Node.js代码：

var express = require("express");
var app = express();
var mysql = require('mysql');
var connection = mysql.createConnection({
  host     : 'host',
  user     : 'user',
  password : 'pswd',
  database : 'db'
});
var bssid, mac, rssi, hotspots_list;
const port = 3000; 
const host = "0.0.0.0";

app.get('/', function (request, response) {
  //Writing data to vars
  bssid = request.query.bssid;
  mac = request.query.mac;
  rssi = request.query.rssi;
  hotspots_list = request.query.hotspots_list;
  //Sending request to MySQL server
  connection.query(`INSERT INTO locations (mac, bssid_current, rssi_currnet, hotspots_list) VALUES ('${mac}','${bssid}','${rssi}','${hotspots_list}')`);
  //Debugging line
  console.log(`BSSID: ${bssid}`);
  //Response
  response.statusCode = 200;
  response.setHeader('Content-Type', 'text/plain');
  return response.send('Done');
});

app.listen(port, host, () => {
  console.log(`Server running!`);
});

在您的代码中，您的路线为/。您正试图通过/server.js

访问它

您添加两种解决方案 app.get('/server.js', [...])或您从网址中删除server.js后访问它。

无法获取和阅读GET请求
