如何服务React [英] How to serve React
问题描述
我有一个简单的React应用程序,我想从我的Go服务器后端提供服务.我听说此过程类似于提供静态html文件,但似乎无法正常工作.
I have a simple React application I would like to serve from my Go server back end. I hear the process is similar to serving a static html file, but I just can't seem to get it to work.
当我尝试在浏览器上查看该应用程序时,它显示此页面无法正常工作",并且本地主机已重定向了太多次"
When I try to view the app on the browser it says "This page isn't working" and that "localhost has redirected too many times"
这是我在本地运行服务器以及尝试处理React应用程序的代码
Here is the code where I am running the server locally as well as trying to handle the react application
func main() {
r := mux.NewRouter()
// handle app
buildHandler := http.FileServer(http.Dir("./client/build/index.html"))
r.PathPrefix("/").Handler(buildHandler)
staticHandler := http.StripPrefix("/static/", http.FileServer(http.Dir("./client/build/static")))
r.PathPrefix("/static/").Handler(staticHandler)
r.HandleFunc("/", index).Methods("GET")
srv := &http.Server{
Handler: r,
Addr: "127.0.0.1:8080",
WriteTimeout: 15 * time.Second,
ReadTimeout: 15 * time.Second,
}
// serve
fmt.Println("Server started on PORT 8080")
log.Fatal(srv.ListenAndServe())
}
这是索引路由的代码
func index(w http.ResponseWriter, r *http.Request) {
// not sure if this is necessary
http.ServeFile(w, r, "index.html")
}
我相信解决方案很简单,而且我很可能在某个地方犯了一个小错误.
I believe the solution is simple and that I am most likely making a small error somewhere.
推荐答案
在您的情况下,仅需要构建处理程序.它必须指向目录而不是文件.除路由外,其他处理程序已过时.
In your case only build handler is needed. It must point to directory not a file. Rest of the handlers are obsolete except the case of routing.
package main
import (
"fmt"
"github.com/gorilla/mux"
"log"
"net/http"
"time"
)
func main() {
r := mux.NewRouter()
r.HandleFunc("/route1", index).Methods("GET")
r.HandleFunc("/route2", index).Methods("GET")
buildHandler := http.FileServer(http.Dir("client/build"))
r.PathPrefix("/").Handler(buildHandler)
srv := &http.Server{
Handler: r,
Addr: "127.0.0.1:8080",
WriteTimeout: 15 * time.Second,
ReadTimeout: 15 * time.Second,
}
fmt.Println("Server started on PORT 8080")
log.Fatal(srv.ListenAndServe())
}
func index(w http.ResponseWriter, r *http.Request) {
http.ServeFile(w, r, "client/build/index.html")
}
只有标准库才能实现同样的效果.
The same can be achieved with the standard library only.
package main
import (
"fmt"
"log"
"net/http"
"time"
)
func main() {
r := http.NewServeMux()
r.HandleFunc("/route1", index)
r.HandleFunc("/route2", index)
buildHandler := http.FileServer(http.Dir("client/build"))
r.Handle("/", buildHandler)
srv := &http.Server{
Handler: r,
Addr: "127.0.0.1:8080",
WriteTimeout: 15 * time.Second,
ReadTimeout: 15 * time.Second,
}
fmt.Println("Server started on PORT 8080")
log.Fatal(srv.ListenAndServe())
}
func index(w http.ResponseWriter, r *http.Request) {
http.ServeFile(w, r, "client/build/index.html")
}
