JSON Request / Response

[tylerd (Tyler)]

Greetings!

Just wondering if it is possible to store key/value pairs in an external config.json file and be able to access those values to use within an HTTP header?

For example, if i have

{
“MyNamespace”:["/mynamespace"]
}

in an external file (which i can access now) and would like to use the MyNamespace value and set it in

req.Header.Set("X-Namespace", <use_MyNameSpaceHere>)

Any ideas if this would work? I’m struggling to figure this one out.

Thanks in advance!

If your JSON config file holds the response header kv pairs in something like:

{
   ..,
   "responseheaders":{"Cache-Control":"no-store"},
   ...
}

that is read into a configuration struct with the following member:

type Context struct {
   ...
   ResponseHeaders  map[string]string
   ...
}
var Ctx Context

Then you can load the response header like this:

func myFileServer(w http.ResponseWriter, r *http.Request) {
   ...
    // load Header k:v pairs
   for k, v := range Ctx.ResponseHeaders {
      w.Header().Set(k, v)
   } 
   ...
}
