两种版本,测试go下载略快,具体自行测试
先利用github官方的api获取最近的 releases信息
https://api.github.com/repos/仓库路径/releases/latest
,go http请求获取 api信息,得到下载链接,再用 http下载文件保存到服务器指定路径
运行示例 go run /goFile/githubDow.go \ -r /BoyceLig/Clash_Chinese_Patch/ \ -p /www/wwwroot/download.gojw.xyz/
#查看帮助
go run /goFile/githubDow.go -help
代码如下(示例):
package main import ( "fmt" "io" "net/http" "os" "encoding/json" "io/ioutil" "strings" "flag" "strconv" ) var repo = flag.String("r", "", "仓库名 /2dust/v2rayN/") var localPath = flag.String("p", "保存路径", " /www/wwwroot/download.gojw.xyz/") var indexs = flag.String("n", "0", "默认0,releases中第几个链接序号,从0开始,如下载第1个和第6个 0,5 ") var remvStrs = flag.String("remove", "", "删除文件关键词 如 clash ") func main() { flag.Parse() // 自动文件下载,比如自动下载图片、压缩包 var rep=*repo var localPathstr=*localPath //先删除特殊关键字文件 v2rayNG files, _ := ioutil.ReadDir(localPathstr) var remvStr =[...]string{*remvStrs} for _, f := range files { for _,r := range remvStr { if r!="" && strings.Contains(f.Name(),r) { os.Remove(localPathstr+f.Name()) } } } r, err := http.Get("https://api.github.com/repos"+rep+"releases/latest") if err != nil { panic(err) } defer func() {_ = r.Body.Close()}() body, _ := ioutil.ReadAll(r.Body) var xxm mybody err = json.Unmarshal(body, &xxm) var indexs=*indexs indexArr := strings.Split(indexs,",") for _,i := range indexArr { //字符串转int i,_ := strconv.Atoi(i) url := xxm.Assets[i].BrowserDownloadURL filenameArr := strings.Split(url,"/") filename := filenameArr[len(filenameArr)-1] fmt.Println("正在下载---------"+filename) DownloadFileProgress(url,localPathstr+filename) } } func downloadFile(url, filename string) { r, err := http.Get(url) if err != nil { panic(err) } defer func() {_ = r.Body.Close()}() f, err := os.Create(filename) if err != nil { panic(err) } defer func() {_ = f.Close()}() n, err := io.Copy(f, r.Body) fmt.Println(n, err) } type Reader struct { io.Reader Total int64 Current int64 } func (r *Reader) Read(p []byte) (n int, err error){ n, err = r.Reader.Read(p) r.Current += int64(n) fmt.Printf("\r进度 %.2f%%", float64(r.Current * 10000/ r.Total)/100) return } func DownloadFileProgress(url, filename string) { r, err := http.Get(url) if err != nil { panic(err) } defer func() {_ = r.Body.Close()}() f, err := os.Create(filename) if err != nil { panic(err) } defer func() {_ = f.Close()}() reader := &Reader{ Reader: r.Body, Total: r.ContentLength, } _, _ = io.Copy(f, reader) } type mybody struct { Assets []Assets `json:"assets"` } type Assets struct { BrowserDownloadURL string `json:"browser_download_url"` }
直接运行:
go run 文件名.go
编译成二进制运行:
go build 文件名.go
./文件名 -help //获取参数提示
./文件名 -r 仓库路径 -p 本地路径
