如何将正文标题添加到Fprintf输出？

package main

import (
    "fmt"
    "os"
)

func main() {
    title := "Hello, World!"
    content := "This is the content of the article."

    // 打开文件，准备写入
    file, err := os.Create("output.txt")
    if err != nil {
        fmt.Println("Failed to create file:", err)
        return
    }
    defer file.Close()

    // 将正文标题添加到输出中
    _, err = fmt.Fprintf(file, "Title: %s\n\n%s", title, content)
    if err != nil {
        fmt.Println("Failed to write to file:", err)
        return
    }

    fmt.Println("Content written to file successfully.")
}
