I am unable to connect to my <em>MySQL</em> database on Azure using Go. I am seeing:
API server listening at: 127.0.0.1:XXXXX

panic: driver: bad connection
goroutine 1 [running]:
db.ConnectToDB(0x134c7aa, 0x5, 0xc0000e6000, 0x9b)
/Users/myuser/go/src/db/db-connection.go:113 +0x249
main.main()

I tried instructions at https://docs.microsoft.com/en-us/azure/mysql/connect-go
package db
import (
"database/sql"
"fmt"
"os"
_ "github.com/go-sql-driver/mysql"
_ "github.com/lib/pq"
)
func ConnectToMydb() {
mysqlInfo := fmt.Sprintf("myusername@myservernameshort:mypassword@tcp" +
"(myservenameshort.database.windows.net:1433)/mydbname?" +
"&allowNativePasswords=true&tls=true&timeout=30s"
)
db, err := sql.Open("mysql", mysqlInfo)
if err != nil {
panic(err)
}
defer db.Close()
err = db.Ping()
if err != nil {
panic(err)
}
fmt.Println("Successfully connected mydb!")
}
My JDBC equivalent connection string is as follows:
jdbc:sqlserver://myservernameshort.database.windows.net:1433;database=mydbname;encrypt=true;trustServerCertificate=false;hostNameInCertificate=*.database.windows.net;loginTimeout=30
and that works.
The instructions at the following link were not clear if I need to go that route:
https://godoc.org/github.com/go-sql-driver/mysql#RegisterTLSConfig
Please guide how I can proceed/ if you need more information/ what I could try

问题描述：访问https出现hostname in certificate didn't match问题，本地测试正常原因是本地环境支持了SNI（Server Name Indication），虚拟主机大力发展起来，造成了一个IP会对应多个域名的情况，SNI就是专门用于解决这个问题，它允许客户端在发起SSL握手请求时，就提交请求的Host信息，使得服务器能够切换到正确的域并返回相应的证书。

第一步，查看mysql是否支持SSL
mysql> show variables like '%ssl%';
如果出现以下结果表示支持，如果没有考虑更换版本，或者编译一个带有SSL版本的mysql

首先跟大家说明一点，我们做 IT 类的外包开发，是非标品开发，所以很有可能在开发过程中会有这样那样的需求修改，而这种需求修改很容易造成扯皮，进而影响到费用支付，甚至出现做完了项目收不到钱的情况。
那么，怎么保证自己的薪酬安全呢？
我们在开工前，一定要做好一些证据方面的准备（也就是“讨薪”的理论依据），这其中最重要的就是需求文档和验收标准。一定要让需求方提供这两个文档资料作为开发的基础。之后开发...
