golang http 返回html文件_Go实战——golang实现MP4视频文件服务器

生命不止，继续 go go go !!!

有点忙，有点懈怠，继续。

关于golang实现的静态文件服务器之前有写过：
Go实战–golang实现静态文件服务器(文件查看，文件上传，文件下载)

正好，最近在做视频方面的东西，那么先来个简单的，实现一个提供mp4视频文件的服务器吧，并且通过浏览器访问播放。

MP4文件服务器

package mainimport (    "log"    "net/http"    "os"    "time")func ServeHTTP(w http.ResponseWriter, r *http.Request) {    video, err := os.Open("./test.mp4")    if err != nil {        log.Fatal(err)    }    defer video.Close()    http.ServeContent(w, r, "test.mp4", time.Now(), video)}func main() {    http.HandleFunc("/", ServeHTTP)    http.ListenAndServe(":8080", nil)}1234567891011121314151617181920212223

package mainimport "io/ioutil"import "log"import "net/http"import "strings"type viewHandler struct{}func (vh *viewHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {    path := r.URL.Path[1:]    data, err := ioutil.ReadFile(string(path))    if err != nil {        log.Printf("Error with path %s: %v", path, err)        w.WriteHeader(404)        w.Write([]byte("404"))    }    if strings.HasSuffix(path, ".html") {        w.Header().Add("Content-Type", "text/html")    } else if strings.HasSuffix(path, ".mp4") {        w.Header().Add("Content-Type", "video/mp4")    }    w.Write(data)}func main() {    http.Handle("/", new(viewHandler))    http.ListenAndServe(":8080", nil)}123456789101112131415161718192021222324252627282930313233

Golang audio/video library and streaming server

我们先浅尝辄止，简单使用一下：

package mainimport (    "fmt"    "github.com/nareix/joy4/av"    "github.com/nareix/joy4/av/avutil"    "github.com/nareix/joy4/format")func init() {    format.RegisterAll()}func main() {    file, _ := avutil.Open("test.mp4")    streams, _ := file.Streams()    for _, stream := range streams {        if stream.Type().IsAudio() {            astream := stream.(av.AudioCodecData)            fmt.Println(astream.Type(), astream.SampleRate(), astream.SampleFormat(), astream.ChannelLayout())        } else if stream.Type().IsVideo() {            vstream := stream.(av.VideoCodecData)            fmt.Println(vstream.Type(), vstream.Width(), vstream.Height())        }    }    file.Close()}123456789101112131415161718192021222324252627282930

输出：
AAC 48000 FLTP 1ch
H264 960 720
