Go API client for vpn

POC Docs for VPN gateway as service

Overview

The IONOS Cloud SDK for GO provides you with access to the IONOS Cloud API. The client library supports both simple and complex requests. It is designed for developers who are building applications in GO . The SDK for GO wraps the IONOS Cloud API. All API operations are performed over SSL and authenticated using your IONOS Cloud portal credentials. The API can be accessed within an instance running in IONOS Cloud or directly over the Internet from any application that can send an HTTPS request and receive an HTTPS response.

Installing

Use go get to retrieve the SDK to add it to your GOPATH workspace, or project's Go module dependencies.

go get github.com/ionos-cloud/sdk-go-bundle/products/vpn.git

To update the SDK use go get -u to retrieve the latest version of the SDK.

go get -u github.com/ionos-cloud/sdk-go-bundle/products/vpn.git

Go Modules

If you are using Go modules, your go get will default to the latest tagged release version of the SDK. To get a specific release version of the SDK use @ in your go get command.

To get the latest SDK repository, use @latest.

go get github.com/ionos-cloud/sdk-go-bundle/products/vpn@latest

Environment Variables

⚠️ Note: To overwrite the api endpoint - api.ionos.com, the environment variable $IONOS_API_URL can be set, and used with NewConfigurationFromEnv() function.

Examples

Examples for creating resources using the Go SDK can be found here

Authentication

Basic Authentication

• Type: HTTP basic authentication

Example

import (
	"context"
	"fmt"
	"github.com/ionos-cloud/sdk-go-bundle/shared"
	vpn "github.com/ionos-cloud/sdk-go-bundle/products/vpn"
	"log"
)

func basicAuthExample() error {
	cfg := shared.NewConfiguration("username_here", "pwd_here", "", "")
	cfg.LogLevel = Trace
	apiClient := vpn.NewAPIClient(cfg)
	return nil
}

Token Authentication

There are 2 ways to generate your token:

Generate token using sdk for auth:

    import (
        "context"
        "fmt"
        "github.com/ionos-cloud/sdk-go-bundle/products/auth"
        "github.com/ionos-cloud/sdk-go-bundle/shared"
        vpn "github.com/ionos-cloud/sdk-go-bundle/products/vpn"
        "log"
    )

    func TokenAuthExample() error {
        //note: to use NewConfigurationFromEnv(), you need to previously set IONOS_USERNAME and IONOS_PASSWORD as env variables
        authClient := auth.NewAPIClient(authApi.NewConfigurationFromEnv())
        jwt, _, err := auth.TokensApi.TokensGenerate(context.Background()).Execute()
        if err != nil {
            return fmt.Errorf("error occurred while generating token (%w)", err)
        }
        if !jwt.HasToken() {
            return fmt.Errorf("could not generate token")
        }
        cfg := shared.NewConfiguration("", "", *jwt.GetToken(), "")
        cfg.LogLevel = Trace
        apiClient := vpn.NewAPIClient(cfg)
        return nil
    }

Generate token using ionosctl:

Install ionosctl as explained here Run commands to login and generate your token.

    ionosctl login
    ionosctl token generate
    export IONOS_TOKEN="insert_here_token_saved_from_generate_command"

Save the generated token and use it to authenticate:

    import (
        "context"
        "fmt"
        "github.com/ionos-cloud/sdk-go-bundle/products/auth"
         vpn "github.com/ionos-cloud/sdk-go-bundle/products/vpn"
        "log"
    )

    func TokenAuthExample() error {
        //note: to use NewConfigurationFromEnv(), you need to previously set IONOS_TOKEN as env variables
        authClient := auth.NewAPIClient(authApi.NewConfigurationFromEnv())
        cfg.LogLevel = Trace
        apiClient := vpn.NewAPIClient(cfg)
        return nil
    }

Certificate pinning:

You can enable certificate pinning if you want to bypass the normal certificate checking procedure, by doing the following:

Set env variable IONOS_PINNED_CERT=<insert_sha256_public_fingerprint_here>

You can get the sha256 fingerprint most easily from the browser by inspecting the certificate.

Depth

Many of the List or Get operations will accept an optional depth argument. Setting this to a value between 0 and 5 affects the amount of data that is returned. The details returned vary depending on the resource being queried, but it generally follows this pattern. By default, the SDK sets the depth argument to the maximum value.

Changing the base URL

Base URL for the HTTP operation can be changed by using the following function:

requestProperties.SetURL("https://api.ionos.com/cloudapi/v6")

Debugging

You can inject any logger that implements Printf as a logger instead of using the default sdk logger. There are log levels that you can set: Off, Debug and Trace. Off - does not show any logs Debug - regular logs, no sensitive information Trace - we recommend you only set this field for debugging purposes. Disable it in your production environments because it can log sensitive data. It logs the full request and response without encryption, even for an HTTPS call. Verbose request and response logging can also significantly impact your application's performance.

package main

    import (
        vpn "github.com/ionos-cloud/sdk-go-bundle/products/vpn"
        "github.com/ionos-cloud/sdk-go-bundle/shared"
        "github.com/sirupsen/logrus"
    )

func main() {
    // create your configuration. replace username, password, token and url with correct values, or use NewConfigurationFromEnv()
    // if you have set your env variables as explained above
    cfg := shared.NewConfiguration("username", "password", "token", "hostUrl")
    // enable request and response logging. this is the most verbose loglevel
    shared.SdkLogLevel = Trace
    // inject your own logger that implements Printf
    shared.SdkLogger = logrus.New()
    // create you api client with the configuration
    apiClient := vpn.NewAPIClient(cfg)
}
