## Debugging a Web Application Example
|
||||
|
||||
Here is an example of how you can use `spew.Sdump()` to help debug a web application. Please be sure to wrap your output using the `html.EscapeString()` function for safety reasons. You should also only use this debugging technique in a development environment, never in production.
|
||||
|
||||
```Go
|
||||
package main
|
||||
|
||||
import (
|
||||
"fmt"
|
||||
"html"
|
||||
"net/http"
|
||||
|
||||
"github.com/davecgh/go-spew/spew"
|
||||
)
|
||||
|
||||
func handler(w http.ResponseWriter, r *http.Request) {
|
||||
w.Header().Set("Content-Type", "text/html")
|
||||
fmt.Fprintf(w, "Hi there, %s!", r.URL.Path[1:])
|
||||
fmt.Fprintf(w, "<!--\n" + html.EscapeString(spew.Sdump(w)) + "\n-->")
|
||||
}
|
||||
|
||||
func main() {
|
||||
http.HandleFunc("/", handler)
|
||||
http.ListenAndServe(":8080", nil)
|
||||
}
|
||||
```
