所谓 hot functions 实际上就是长时间运行的functions ，简单理解类似后台任务
fnproject 使用 类似 http的处理方式
package main
import (
"bufio"
"bytes"
"fmt"
"io/ioutil"
"net/http"
"os"
"strconv"
)
func main() {
for {
res := http.Response{
Proto: "HTTP/1.1",
ProtoMajor: 1,
ProtoMinor: 1,
StatusCode: 200,
Status: "OK",
}
r := bufio.NewReader(os.Stdin)
req, err := http.ReadRequest(r)
var buf bytes.Buffer
if err != nil {
res.StatusCode = 500
res.Status = http.StatusText(res.StatusCode)
fmt.Fprintln(&buf, err)
} else {
l, _ := strconv.Atoi(req.Header.Get("Content-Length"))
p := make([]byte, l)
r.Read(p)
fmt.Fprintf(&buf, "Hello %s\n", p)
for k, vs := range req.Header {
fmt.Fprintf(&buf, "ENV: %s %#v\n", k, vs)
}
}
res.Body = ioutil.NopCloser(&buf)
res.ContentLength = int64(buf.Len())
res.Write(os.Stdout)
}
}
format (mandatory) either "default" or "http". If "http", then it is a hot function.
idle_timeout (optional) - idle timeout (in seconds) before function termination, default 30 seconds.
