After I watched this video, I try it myself. However, I get the panic error panic: open templates/index.html: The system cannot find the path specified. The Complete erroe message is like the following.
Hello, Go Web Development 1.3
panic: open templates/index.html: The system cannot find the path specified.
goroutine 1 [running]:
panic(0x789260, 0xc082054e40)
F:/Go/src/runtime/panic.go:481 +0x3f4

main.main()
E:/Users/User/Desktop/codespace/go_workspace/src/go-for-web-dev/src/1.3_UsingTemplate.go:11 +0x20d
I have tried different string like "templates/index.html", "index.html", "./template/index.html"... Also, I try to copy the entire template folder into pkg, bin...But I get the same error message.
The following is the go program (1.3_UsingTemplate.go).
package src
import (
"fmt"
"net/http"
"html/template"
)
func main() {
fmt.Println("Hello, Go Web Development 1.3")
templates := template.Must(template.ParseFiles("templates/index.html")) //This line should have some problem
http.HandleFunc("/", func(w http.ResponseWriter, r *http.Request) {
if err := templates.ExecuteTemplate(w, "index.html", nil); err != nil {
http.Error(w, err.Error(), http.StatusInternalServerError)
}
})
fmt.Println(http.ListenAndServe(":8080",nil))
}
File Structure
Update
To solve this problem, I need to first change the current working directory to the folder containing the *.go file. Then, execute go run {filename.go}. In GoClipse, is there any setting can be set to the Run Configurations for automatically changing the current working directory to the folder containing the *.go file?
