如何从共享的play.golang.org网址中检索golang代码

I need to read golang code from the play.golang.org link and save to a .go file. I'm wondering if there is any public API support for play.golang.org. I googled but no hints. Has anyone attempted anything similar?

    To get the text of a shared playground program, append ".go" to the URL. For example, you can get the text of the program at https://play.golang.org/p/HmnNoBf0p1z with https://play.golang.org/p/HmnNoBf0p1z.go.

    You can upload a program by posting the program text to https://play.golang.org/share. The response is the ID of the shared program. This program uploads stdin to the playground and prints the ID of the uploaded program to stdout:

    package main
    
    import (
        "io"
        "log"
        "net/http"
        "os"
    )
    
    func main() {
        req, err := http.NewRequest("POST", "https://play.golang.org/share", os.Stdin)
        if err != nil {
            log.Fatal(err)
        }
        resp, err := http.DefaultClient.Do(req)
        if err != nil {
            log.Fatal(err)
        }
        defer resp.Body.Close()
        io.Copy(os.Stdout, resp.Body)
    }  
    

    Assuming the above program is in upload.go, the following shell script prints HmnNoBf0p1z.

    go run upload.go << EOF
    package main
    
    import (
        "fmt"
    )
    
    func main() {
        fmt.Println("Hello, playground")
    }
    EOF
    

    If you want to download the program as a file using a browser, then add the query ?download=true to the .go URL. Example: https://play.golang.org/p/HmnNoBf0p1z.go?download=true
