How do i pass a Golang variable to Bash Script?
问题
script.sh
>
#!/bin/shdbt run --select $model_tag --profiles-dir .
想要运行这个 shell 脚本，从我的 .go 文件中获取变量 model_tag
invoke.go
>
package mainimport ("fmt""log""net/http""os""os/exec")func handler(w http.ResponseWriter, r *http.Request) {log.Print("helloworld: received a request")mt := r.Header.Get("Model-Tag")cmd := exec.CommandContext(r.Context(), "/bin/sh", "script.sh")cmd.Env = append(os.Environ(), fmt.Sprintf("model_tag=%s", mt))cmd.Stderr = os.Stderrout, err := cmd.Output()if err != nil {w.WriteHeader(500)}w.Write(out)}func main() {log.Print("helloworld: starting server...")http.HandleFunc("/", handler)port := os.Getenv("PORT")if port == "" {port = "8080"}log.Printf("helloworld: listening on %s", port)log.Fatal(http.ListenAndServe(fmt.Sprintf(":%s", port), nil))}
在这里，mt 是从请求中接收到的头部信息，我需要在执行 shell 脚本之前将其传递给脚本。
如何在使用 go 文件执行 shell 脚本之前设置 model_tag = mt？
尝试直接设置 model_tag = mt，会抛出语法错误。

Want to run this shell script that takes the Variable model_tag from my .go file
invoke.go
>
package mainimport ("fmt""log""net/http""os""os/exec")func handler(w http.ResponseWriter, r *http.Request) {log.Print("helloworld: received a request")mt := r.Header.Get("Model-Tag")cmd := exec.CommandContext(r.Context(), "/bin/sh","script.sh")cmd.Stderr = os.Stderrout, err := cmd.Output()if err != nil {w.WriteHeader(500)}w.Write(out)}func main() {log.Print("helloworld: starting server...")http.HandleFunc("/", handler)port := os.Getenv("PORT")if port == "" {port = "8080"}log.Printf("helloworld: listening on %s", port)log.Fatal(http.ListenAndServe(fmt.Sprintf(":%s", port), nil))}
Here, mt is the header being received from a request, that i need to pass to the shell script before execution?
How do i set model_tag = mt before executing the shell script using the go file?
Tried setting model_tag = mt directly, throws a syntax error

在执行运行 script.sh 的命令之前，执行以下操作：
os.Setenv("model_tag", mt)
英文:
Before executing your cmd which runs script.sh, do a
os.Setenv("model_tag", mt)

尝试使用以下代码：
cmd := exec.CommandContext(r.Context(), "/bin/sh", fmt.Sprintf("model_tag=%s script.sh", mt))
请注意，这是一段Go语言代码，用于执行Shell命令。
英文:
try with
cmd := exec.CommandContext(r.Context(), "/bin/sh",fmt.Sprintf("model_tag=%s script.sh",mt))
