got未写入软件包数据

Posted 2023-03-13

如果Golang未写入软件包数据，可能是因为以下原因：
1. Golang程序没有正确安装，请重新安装。
2. 环境变量设置不正确，请检查环境变量配置是否正确。
3. 没有正确下载Golang的软件包，请重新下载所需的软件包。
4. 操作系统的权限不足，导致无法写入软件包数据，请检查系统权限并更改权限为可写。 参考技术A 我正在尝试探索 Go 并发性。这里Grabber()打印并写入执行结果。程序打印预期结果，但不将其写入urls.txt. 谁能向我解释我在这里缺少什么？

main.go

package main

import (

"bufio"

"fmt"

"io/ioutil"

"log"

"net/http"

"os"

"regexp"

"strings"

"sync"

)

var wg sync.WaitGroup

var mt sync.Mutex

// Final Literation

func main()

file, err := os.Open("ip.txt")

if err != nil

log.Fatal(err)



defer file.Close()

scanner := bufio.NewScanner(file)

for scanner.Scan()

go Grabber(scanner.Text())

wg.Add(1)



wg.Wait()

if err := scanner.Err(); err != nil

log.Fatal(err)





// stringInArray do If string in list return true false otherwise.

func stringInArray(a string, list []string) bool

for _, b := range list

if b == a

return true





return false



// Grabber Do Search the bing and collect array of sitelist

func Grabber(ip string)

defer wg.Done()

var output []string

outfile, err := os.Create("urls.txt")

if err != nil

log.Fatal(err)



defer outfile.Close()

if ip == ""



page := 1

for page < 251

client := &http.Client

req, err := http.NewRequest(

http.MethodGet,

fmt.Sprintf(

"http://www.bing.com/search?q=ip:%s+&count=50&first=1",

ip,

),

nil,

)

if err != nil



req.Header.Set("User-Agent", "Mozilla/5.0 (Windows NT 6.1; rv:57.0) Gecko/20100101 Firefox/57.0")

res, err := client.Do(req)

if err != nil

fmt.Println("Invalid Request")



defer res.Body.Close()

body, err := ioutil.ReadAll(res.Body)

if err != nil

fmt.Println("Couldn't Read")



ip.txt 作为输入
