Go语言中如何处理并发文件的文件系统文件日志和审计日志问题？

package main

import (
    "fmt"
    "os"
)

func main() {
    fileName := "log.txt"
    file, err := os.Create(fileName)
    if err != nil {
        fmt.Println("创建文件失败：", err)
        return
    }
    defer file.Close()

    content := "这是一条日志"
    _, err = file.WriteString(content)
    if err != nil {
        fmt.Println("写入文件失败：", err)
        return
    }

    fmt.Println("日志写入成功")
}

package main

import (
    "fmt"
    "os"
    "sync"
)

func main() {
    fileName := "log.txt"
    file, err := os.Create(fileName)
    if err != nil {
        fmt.Println("创建文件失败：", err)
        return
    }
    defer file.Close()

    var wg sync.WaitGroup
    var mu sync.Mutex

    content := "这是一条日志"

    for i := 0; i < 10; i++ {
        wg.Add(1)
        go func(i int) {
            defer wg.Done()
            mu.Lock()
            defer mu.Unlock()

            _, err := file.WriteString(fmt.Sprintf("%s-%d
", content, i))
            if err != nil {
                fmt.Println("写入文件失败：", err)
                return
            }
        }(i)
    }

    wg.Wait()

    fmt.Println("日志写入成功")
}

        return
    }
    defer file.Close()
