Why does the page accessing the Go project display a 404 error after it is built? How to solve it?

Troubleshooting and solving the access page after the Go project is built.

After the Go language project is successfully built, the access page shows an error of 404, which is a common development problem. This article will analyze this problem in depth and provide effective solutions.

Problem description

The developer successfully built the Go project using go build -o test . command, but after deploying to the server, accessing the page returned a 404 error. The developer suspects that static files (HTML, CSS, JavaScript, etc.) are not included correctly.

Problem analysis

The go build command only compiles Go code and does not automatically process static files. Static files require additional processing to be properly accessed. Server configuration, especially the configuration of static file services, can also cause problems.

Solution

1. Using Go's built-in http.FileServer : Go's http.FileServer can easily handle static files. Add the following code to your Go program:

    package main
   
   import (
       "net/http"
   )
   
   func main() {
       http.Handle("/", http.FileServer(http.Dir("./static")))
       http.ListenAndServe(":8080", nil)
   }

   Make sure your static files are in the static directory.

2. Embed static files using go-bindata : The go-bindata tool allows you to embed static files into Go executable files. In your main.go :

    package main
   
   import (
       "net/http"
       _ "github.com/go-bindata/go-bindata/testdata" // Replace with your binda package)
   
   func main() {
       http.Handle("/", http.FileServer(http.FS(bindata.AssetFS()))) // Use binddata.AssetFS()
       http.ListenAndServe(":8080", nil)
   }

   You need to use the go-bindata command to generate the bindata.go file and include it in your project.

3. Check server configuration: Make sure that the server is configured correctly, especially when using reverse proxy or load balancing, make sure they forward requests correctly to your Go program. Check that the server is pointing to your executable correctly and that the static file path is correct.

Through the above method, you should be able to solve the problem of 404 error after the Go project is built. The key is to ensure that static files are processed and served correctly. If the problem persists, please check your routing configuration and server logs for more information.
