如何在 golang 中的 SSH 中获取身份验证回调的连接字符串?

php editor Youzi will introduce to you how to get the connection string of the authentication callback in SSH in golang. In the SSH protocol, the authentication callback is an important link, which is used to verify the client's identity and establish a secure connection. In order to obtain the connection string for the authentication callback, we can use the functions and methods provided by the ssh package in golang with the correct parameters and settings. In the following article, we will explain this process in detail to help you handle SSH connections and authentication flexibly in golang.

Question content

My server configuration code is:

serverConfig := ssh.ServerConfig{
        PublicKeyCallback: func(c ssh.ConnMetadata, pubKey ssh.PublicKey) (*ssh.Permissions, error) {
        ...
    }
}

I start the ssh connection using something like ssh://user@host:port/path. How do I get the path part of the ssh connection string in this callback or any other callback that can check the user key/password?

Solution

SSH is different from http, which contains ssh://user@host:port/path. The format is indeed user@host:port but it does not require ssh:// and path construction. In your question, PublicKeyCallback is using the public key. If you are performing a custom action, do it outside of PublicKeyCallback.

The above is the detailed content of How to get connection string for authentication callback in SSH in golang?. For more information, please follow other related articles on the PHP Chinese website!

Go Error Handling: Best Practices and PatternsGo Error Handling: Best Practices and PatternsMay 04, 2025 am 12:19 AM

In Go programming, ways to effectively manage errors include: 1) using error values ​​instead of exceptions, 2) using error wrapping techniques, 3) defining custom error types, 4) reusing error values ​​for performance, 5) using panic and recovery with caution, 6) ensuring that error messages are clear and consistent, 7) recording error handling strategies, 8) treating errors as first-class citizens, 9) using error channels to handle asynchronous errors. These practices and patterns help write more robust, maintainable and efficient code.

How do you implement concurrency in Go?How do you implement concurrency in Go?May 04, 2025 am 12:13 AM

Implementing concurrency in Go can be achieved by using goroutines and channels. 1) Use goroutines to perform tasks in parallel, such as enjoying music and observing friends at the same time in the example. 2) Securely transfer data between goroutines through channels, such as producer and consumer models. 3) Avoid excessive use of goroutines and deadlocks, and design the system reasonably to optimize concurrent programs.

Centralized Error Handling Strategies in GoCentralized Error Handling Strategies in GoMay 03, 2025 am 12:17 AM

Centralized error handling can improve the readability and maintainability of code in Go language. Its implementation methods and advantages include: 1. Separate error handling logic from business logic and simplify code. 2. Ensure the consistency of error handling by centrally handling. 3. Use defer and recover to capture and process panics to enhance program robustness.
