我想使用 go mux 在子路径（例如 http://localhost:3000/app/）下显示编译的 Angular 项目在没有子路径“app/”的情况下，它可以按预期工作但是当我使用 http.StripPrexix("/app/, ..) 处理程序添加子路径时，仅找到并呈现索引 html，但没有所有 css、js 文件。测试代码package mainimport ( "log" "net/http" "github.com/gorilla/mux")func main() { mux := mux.NewRouter() fs := http.FileServer(http.Dir("./static/")) // Serve static files mux.PathPrefix("/app/").Handler(http.StripPrefix("/app/", fs)) log.Println("Listening...") http.ListenAndServe(":3000", mux)}索引.html<!doctype html><html><head> <meta charset="utf-8"> <title>TestProject</title> <base href="/"> <meta name="viewport" content="width=device-width, initial-scale=1"> <link rel="icon" type="image/x-icon" href="favicon.ico"><link rel="stylesheet" href="styles.3ff695c00d717f2d2a11.css"></head><body> <h1>Should work</h1> <app-root></app-root><script src="runtime.359d5ee4682f20e936e9.js" defer></script><script src="polyfills.bf99d438b005d57b2b31.js" defer></script><script src="main.5dd083c1a27b2a7e410a.js" defer></script></body></html>工作项目下载该项目还包括要服务的静态文件https://filehorst.de/d/dubJmmsz目标服务不同路径下的不同项目关注这个问题我究竟做错了什么？如何在 eg: localhost:3000/app/ 下为整个项目服务

gorilla mux 文档提到了如何处理 Angular SPA 应用程序。
但是，由于您希望将 SPA 根目录基于子目录，因此您还需要在 HTML/JS 中进行更改。基本目录应该是一个变量，与 SPA 的前缀相同。我相信这更像是一个设计问题
否则，由于除索引之外的其余文件都在根目录下解析，因此其余文件需要回退到“/”并且都已配置。
router.PathPrefix("/app").Handler(spa)
router.PathPrefix("/").Handler(spa)
所以尝试如下。我尝试了以下静态文件夹：
package main
import (
"log"
"net/http"
"os"
"path/filepath"
"time"
"github.com/gorilla/mux"
)
type spaHandler struct {
staticPath string
indexPath string
}
func (h spaHandler) ServeHTTP(w http.ResponseWriter, r *http.Request) {
// get the absolute path to prevent directory traversal
path, err := filepath.Abs(r.URL.Path)
if err != nil {
// if we failed to get the absolute path respond with a 400 bad request
// and stop
http.Error(w, err.Error(), http.StatusBadRequest)
return
}
// prepend the path with the path to the static directory
path = filepath.Join(h.staticPath, path)
// check whether a file exists at the given path
_, err = os.Stat(path)
if os.IsNotExist(err) {
// file does not exist, serve index.html
http.ServeFile(w, r, filepath.Join(h.staticPath, h.indexPath))
return
} else if err != nil {
// if we got an error (that wasn't that the file doesn't exist) stating the
// file, return a 500 internal server error and stop
http.Error(w, err.Error(), http.StatusInternalServerError)
return
}
// otherwise, use http.FileServer to serve the static dir
http.FileServer(http.Dir(h.staticPath)).ServeHTTP(w, r)
}
func main() {
router := mux.NewRouter()
spa := spaHandler{staticPath: "static", indexPath: "index.html"}
router.PathPrefix("/app").Handler(spa)
srv := &http.Server{
Handler: router,
Addr: ":3000",
// Good practice: enforce timeouts for servers you create!
WriteTimeout: 15 * time.Second,
ReadTimeout: 15 * time.Second,
}
log.Fatal(srv.ListenAndServe())
}
