# golang WebDav服务 #

golang官方提供了webdav服务包，但是，功能比较有限，这里主要针对一个端口，多目录做解释

# 普通WebDav服务 #

package main
    
    import (
        "net/http"
        "golang.org/x/net/webdav"
    )
    
    func main() {
        
        http.ListenAndServe(":8080", &webdav.Handler{
        
            FileSystem: webdav.Dir("."),
            LockSystem: webdav.NewMemLS(),
        })
    }

# 一个端口共享多用户/多目录 #

package main
    
    import (
    	"fmt"
    	"golang.org/x/net/webdav"
    	"log"
    	"net/http"
    	"strings"
    )
    
    func Dav_Load() {
        
    	s_mux := http.NewServeMux();
    	fs := &webdav.Handler{
        
    		Prefix:     "/dav/",
    		FileSystem: webdav.Dir("F:/"),
    		LockSystem: webdav.NewMemLS(),
    	}
    
    	fs2 := &webdav.Handler{
        
    		Prefix:     "/dav2/",
    		FileSystem: webdav.Dir("E:/"),
    		LockSystem: webdav.NewMemLS(),
    	}
    	s_mux.HandleFunc("/", func(w http.ResponseWriter, req *http.Request) {
        
    		//log.Println(req.RequestURI)
    		// 获取用户名/密码
    		username, password, ok := req.BasicAuth()
    		if !ok {
        
    			w.Header().Set("WWW-Authenticate", `Basic realm="Restricted"`)
    			w.WriteHeader(http.StatusUnauthorized)
    			return
    		}
    		// 验证用户名/密码
    		if username != "a" || password != "b" {
        
    			http.Error(w, "WebDAV: need authorized!", http.StatusUnauthorized)
    			return
    		}
    
    		//switch req.Method {
        
    		//case "PUT", "DELETE", "PROPPATCH", "MKCOL", "COPY", "MOVE":
    		//	http.Error(w, "WebDAV: Read Only!!!", http.StatusForbidden)
    		//	return
    		//}
    		if strings.HasPrefix(req.RequestURI, fs.Prefix) {
        
    			fs.ServeHTTP(w, req)
    			//fmt.Println("fs call")
    			return
    		}
    		if strings.HasPrefix(req.RequestURI, fs2.Prefix) {
        
    			fs2.ServeHTTP(w, req)
    			//fmt.Println("fs2 call")
    			return
    		}
    
    		// else
    		w.WriteHeader(404)
    	})
    
    	dav_addr := fmt.Sprintf(":%v", 8082)
    	log.Println("Dav Server run ", dav_addr)
    	err := http.ListenAndServe(dav_addr, s_mux)
    	if (err != nil) {
        
    		fmt.Println("dav server run error:", err)
    	}
    }
    
    func main() {
        
    	Dav_Load()
    }
