无法使用Google App Engine中的SSL + Golang连接到Google Cloud SQL [英] Cannot connect to Google Cloud SQL using SSL + Golang from Google App Engine

问题描述

谷歌表示，你可以使用Golang和 go-sql-driver 连接到Google Cloud SQL，如下所示：

  importdatabase / sql
 import _github.com/go-sql-driver/mysql
 $ b $ db，err：= sql .Open（mysql，user @ cloudsql（project-id：instance-name）/ dbname）
  

ref： https://cloud.google.com/appengine/ docs / go / cloud-sql / reference

...然而，这（对我来说）会产生一个x509证书错误：

$ b

x509：证书适用于projectName：instanceName，而不是
projectName

我无法弄清楚如何解决这个问题。根据Google自己的文档，在连接字符串中再次添加实例名称（即使它已经在那里）并没有帮助，也不是正确的。

有没有人设法做到这一点工作？什么是错的？

解决方案

您是否使用SSL连接？此错误消息表明，当您使用mysql驱动程序注册自定义TLSConfig时，必须设置 ServerName 属性，除 之外指定 project-id：instance-name 内部 sql.Open（）。

如从文档使用TLS设置，但添加 ServerName 在 RegisterTLSConfig 的调用中：

  mysql.RegisterTLSConfig（custom，& tls.Config {
 RootCAs：rootCertPool，
证书：clientCert，
 ServerName：projectName：instanceName，$ b $然后追加？tls = nameOfYourCustomTLSConfig  >  

>

  db，err：= sql.Open（mysql，user @ cloudsql（project-id：instance-name ）/ dbname？tls = custom）
  

Google says you can connect to Google Cloud SQL using Golang and the go-sql-driver like so:

import "database/sql"
import _ "github.com/go-sql-driver/mysql"

db, err := sql.Open("mysql", "user@cloudsql(project-id:instance-name)/dbname")

ref: https://cloud.google.com/appengine/docs/go/cloud-sql/reference

... However, this (for me) generates a x509 certificate error:

x509: certificate is valid for projectName:instanceName, not projectName

I cannot figure out how to solve this. Adding the instance name again (even though it's already there) in the connection string does not help, nor is correct according to Google's own docs.

Has anyone managed to make this work? What is wrong?

解决方案

Are you connecting with SSL? This error message indicates that must set the ServerName property when you register your custom TLSConfig with the mysql driver, in addition to specifying the project-id:instance-name inside sql.Open().

e.g. Use the TLS setup from the docs, but add a ServerName in your call to RegisterTLSConfig:

mysql.RegisterTLSConfig("custom", &tls.Config{
            RootCAs:      rootCertPool,
            Certificates: clientCert,
            ServerName:   "projectName:instanceName",
        })

Then append ?tls=nameOfYourCustomTLSConfig

db, err := sql.Open("mysql", "user@cloudsql(project-id:instance-name)/dbname?tls=custom")
