Copy from: https://zetcode.com/golang/exec-command/ Go exec command tutorial shows how to execute shell commands and programs in Golang. The Run function starts the specified command and waits for it to complete, while the Start starts the specified command but does not wait for it to complete; we need to use Wait with Start. Go os/exec The os/exec package runs external commands. It wraps os.StartProcess to make it…
Trước đó mình đã có 1 bài hướng dẫn các bạn tạo cli tool cho riêng mình bằng Golang. Sau khi code xong chúng ta sẽ public cli.Nhưng chúng ta không thể build Binary trên từng hệ điều hành rồi mới push chúng lên release được. chúng ta sẽ dùng 1 lệnh và build chúng…

Giờ mình sẽ cần tạo 1 page chứa…
Here are some Go packages similar in functionality to go-cache: Coding To print each individual value stored under the myKey key in BigCache, you can split the retrieved concatenated string into its constituent parts. Since the values are concatenated with spaces as separators, you can use strings.Split to divide the string into separate values and…

To receive results in the main function from StartKafkaConsumer, you can use a Go channel. Channels are a powerful feature in Go for communication between goroutines. Here’s how you can modify your program: 1. Modify StartKafkaConsumer to Use Channels Update the StartKafkaConsumer function to send Kafka messages through a channel. You’ll also need to pass…
