Question

面对这样的问题，我无法将 Cloud Functions连接到Cloud SQL 数据库

我用来连接数据库的代码：

var mysql = require('mysql');
exports.mysql = function handler(req, res) {
    var c = mysql.createConnection({
        socketPath: '/cloudsql/' + 'instance Connection Name',
        user: 'root',
        password: 'lns12345',
        database: 'Sample'
    });
    c.connect();
    c.query('SELECT * from user', req.body.user, function(e, results) {
        //made reply here
        if (results) {
            console.log('Database succeed')
        } else {
            console.log('new error created')
        }
        console.log('my E result is :', e)
        console.log('My results is :', results)
    });

};

我收到的错误消息：

Error: function crashed. Details:
connect ECONNREFUSED /cloudsql/'instance Connection Name'

我在Cloud Functions中获得的详细日志：

用实际的连接名称替换@NgModule({ entryComponents: [AComponent, BComponent, ...] ... }) export class AppModule { constructor() {} ngDoBootstrap(app: ApplicationRef) { if (Math.random() > 0.5) { appRef.bootstrap(AComponent, '#app'); } else { appRef.bootstrap(BComponent, '#app'); } }占位符

错误：功能崩溃。详细信息：connect ECONNREFUSED / cloudsql / <实例连接=“ =” name =“” >>
