尝试从云功能连接到 Cloud-sql sql-server 时出现连接错误

Question

我正在使用 firebase 函数连接到云-sql（Microsoft SQL 服务器）。我尝试了以下通过 public ip:

连接到 SQL 服务器

/*Tedious Start*/
var TediousConnection = require('tedious').Connection;
var TediousRequest = require('tedious').Request;
var TediousTypes = require('tedious').TYPES;
const config = {
  user: 'admin',
  password: 'password',
  server: '12.345.5.678',
  database: 'mma',
  //host: 'myproject:us-central1:my-db'
};
app.get('/mssql/', async(req, res) => {
  var sql = require('mssql');
  sql
    .connect(config)
    .then(function() {
      //6.
      var request = new sql.Request();
      //7.
      request
        .query('SET NOCOUNT ON;select * from student')
        .then(function(recordset) {
          // send records as a response
          res.send(recordset.recordset);
          sql.close();
        })
        .catch(function(err) {
          //8.
          console.log(err);
          sql.close();
        });
      res.end();
    })
    .catch(function(err) {
      //9.
      console.log(err);
    });
});

我收到以下错误：

{ ConnectionError: Failed to connect to 12.345.5.678:1433 in 15000ms

  name: 'ConnectionError' }

我认为 cloudfunction 无法访问 sql 服务器。我还尝试添加服务帐户以获得云sql 权限。

我认为我的云函数有问题，并尝试使用云函数中的 cloudsql-postgresql。我能够从云功能成功连接到 ClouSQL-postgresql。

例如，在云sql-postgresql 的情况下，主机使用 unix 域套接字采用类似于以下的值：

config.host = `/cloudsql/${process.env.CLOUD_SQL_CONNECTION_NAME}`;

如果是 Cloudsql-mssql，我将提供服务器的 IP 地址。我不知道我错过了什么。我需要处理防火墙问题吗？

根据 documentation:

Cloud Functions does not support connecting to Cloud SQL for SQL Server over public IP. Use private IP instead

相反，您应该使用实例的专用 IP 地址和端口 1433 直接连接。
