路线联盟

const express = require('express')
const router = express.Router()
const connection = require('../../Config/database')
const controllerAdmin = require('../../controllers/Administration')
const controlleruser = require('../../controllers/Alliances')
router.get('/Administration/Alliances', (req, res) => controllerAdmin.findcidade3(connection, req, res))
router.get('/Administration/Alliances/limitado', (req, res) => controlleruser.findAlianca(connection, req, res))


module.exports = app => app.use('/', router)

我的应用

require('./routes/Administration/Alliances')(app)

我的连接数据库

const mysql = require('mysql')
const config = require( "./config.json" )
const connection =mysql.createConnection({
 host:config.host,
 user:config.user,
 password:config.password,
 database:config.database,
// port:config.port
});

connection.connect((err) =>{
    if(err){
        console.log(err)
        process.exit(0)
    }else{
    console.log('database on')
}
})

我做错了什么我找不到解决方案

最佳答案

不确定您要问什么，但是，如果要在同一路由/ API中调用多个函数，可以执行以下操作：

使用expressJs可以使用next函数，例如：

app.get('/Administration/Alliances', (req, res, next) => {
    //Do something here and to add data to your request use
    req.body.newData = 'newData';
    //after this just call next function
    next();
}, (req, res, next) => {
    //Can continue this cycle of calling next function until last `sendResponse` function is reached.
    //Can even set `error` in request for `sendResponse`
    req.error = "Some error";
    next();
}, (req, res) => {
    if(req.error) {
        res.status(400).send(req.error);
    } else {
        res.status(200).send(req.body.result);
    }
});
