如何在 Hana DB 上连接 SSL - SAP [SQL 错误 4321 - 只允许安全连接]

Question

在 link SAP - Go (golang) Support 之后编写了以下代码：

package main

import (
    "database/sql"
    _ "github.com/SAP/go-hdb/driver"
    "log"
)

const (
    driverName = "hdb"
    hdbDsn     = "hdb://user:password@hostname:port"
)

func main() {

    db, err := sql.Open(driverName, hdbDsn)

    if err != nil {
        log.Print("error on sql open => " ,err)
    }

    err = db.Ping()

    if err != nil {
        log.Print("error on db.Ping() => " ,err)
    }

}

但我有以下问题:

2019/11/04 14:59:24 error on db.Ping() => SQL Error 4321 - only secure connections are allowed

我也试过这个：

hdbDsn     = "hdb://user:password@hostname:port?encrypt=true"

但无法连接到 Hana 数据库。

有人可以帮助我吗？

Answer 1

纯 Go HANA SQL 客户端库很可能不支持加密（类似于纯 Python 客户端）。您应该使用官方 HANA go 客户端 (https://help.sap.com/viewer/0eec0d68141541d1b07893a39944924e/2.0.04/en-US/0ffbe86c9d9f44338441829c6bee15e6.html) 并设置连接属性：

加密=真
验证证书=假

Answer 2

经过大量测试，我找到了这个姑息解决方案：

package main

import (
    "crypto/tls"
    "database/sql"
    "github.com/SAP/go-hdb/driver"
    _ "github.com/SAP/go-hdb/driver"
    "log"
)

const (
    HOST     = "host"
    PORT     = ":port"
    USERNAME = "user"
    PASSWORD = "password"
)

func main() {
    c := driver.NewBasicAuthConnector(
        HOST+PORT,
        USERNAME,
        PASSWORD)

    tlsConfig := tls.Config{
        InsecureSkipVerify: false,
        ServerName:         HOST,
    }

    c.SetTLSConfig(&tlsConfig)

    db := sql.OpenDB(c)

    var id int
    var name string
    res := db.QueryRow("SELECT * FROM SCHEMA.TABLE LIMIT 1")

    res.Scan(&id, &name)

    log.Println("res ", id, name)

}
