In recent years, with the continuous popularity of Go language applications, the problem of Golang exec garbled characters has also begun to attract widespread attention. When using the golang exec command to execute external commands, garbled characters often occur, which makes many developers have to spend a lot of time dealing with this problem in actual development. What exactly is causing this problem? How to solve it? This article will elaborate on the root cause of the problem and the solution.
The root cause of the Golang exec garbled code problem
First of all, let’s look at the root cause of the Golang exec garbled code problem. In fact, the occurrence of this problem is related to Chinese encoding. The Golang exec command will follow the encoding of the current operating system when executing external commands. Therefore, if the encoding of the current operating system is inconsistent with the encoding of the external command being executed, garbled characters will occur. For example, in the Windows operating system, if the current encoding is GBK and the encoding of the executed external command is UTF-8, the output result will be garbled.
Methods to solve the Golang exec garbled code problem
We have the following solutions to the root cause of the Golang exec garbled code problem.
Method 1: Use Unicode encoding
Unicode can represent characters in all languages, so using Unicode encoding can effectively solve the problem of Golang exec garbled characters. For specific implementation, we can use the utf8 package in the Go language to convert strings. The sample code is as follows:
cmd := exec.Command("cmd", "/C", "echo", "你好") buf, err := cmd.Output() if err != nil { fmt.Println(err) return } fmt.Println(string(buf))
Method 2: Set the environment variable of the external command
Another way to solve the Golang exec garbled problem is to set the environment variable of the external command. In specific implementation, we can use the Setenv method in the os package to set the environment variables of external commands. The sample code is as follows:
cmd := exec.Command("cmd", "/C", "echo", "你好") cmd.Env = append(cmd.Env, "CHCP 65001") buf, err := cmd.Output() if err != nil { fmt.Println(err) return } fmt.Println(string(buf))
Method 3: Specify the encoding in the external command
In addition, we can also specify the encoding in the external command to solve the Golang exec garbled problem. In specific implementation, we can use the chcp command to set the current encoding. The sample code is as follows:
cmd := exec.Command("cmd", "/C", "chcp 65001 && echo 你好") buf, err := cmd.Output() if err != nil { fmt.Println(err) return } fmt.Println(string(buf))
Summary
Golang exec garbled code problem is a common problem in Golang development, but by analyzing the root cause of the problem, we can use a variety of methods to solve this problem. In general, we can use Unicode encoding, set environment variables of external commands, or specify encoding in external commands to solve the Golang exec garbled problem. I hope this article can help everyone understand and solve this problem.
