Go语言命令行参数字符串如何转换为自定义结构体？

package main

import (
    "flag"
    "fmt"
)

type poc struct {
    method     string
    headers    headers
    path       string
    body       string
    expression int
}

type headers struct {
    useragent    string
    accept       string
    xforwardedfor string
    contenttype  string
    referer      string
    acceptlanguage string
    cookie       string
}

var h1 = poc{
    method: "get",
    path:   "/resin-doc/viewfile/?file=index.jsp",
    body:   "",
    expression: 200,
    headers: headers{
        useragent:    "mozilla/5.0 (windows nt 6.1; wow64) applewebkit/537.36 (khtml, like gecko) chrome/63.0.3239.132 safari/537.36",
        accept:       "",
        xforwardedfor: "",
        contenttype:  "",
        referer:      "",
        acceptlanguage: "",
        cookie:       "",
    },
}

package main

import (
    "flag"
    "fmt"
)

// ... (Poc and headers struct definitions remain the same) ...

func main() {
    var module string
    flag.StringVar(&module, "m", "H1", "module: all")
    flag.Parse()

    pocMap := map[string]poc{
        "H1": h1,
        // Add other Poc structs here as needed
    }

    poc, ok := pocMap[module]
    if !ok {
        fmt.Println("Invalid module name")
        return
    }

    method, path, header, body := getpocinfo(poc)
    fmt.Printf("%s:%s:%s:%s\n", method, path, header, body)
}

func getpocinfo(id poc) (method string, path string, header string, body string) {
    method = id.method
    path = id.path
    header = id.headers.useragent //Corrected to access useragent
    body = id.body
    return
}
