POST Method override

[Dexus]

Hello @kataras,

would it be possible to add a optional "Method Override"?

Like https://www.npmjs.com/package/method-override or http://fandry.blogspot.com/2012/03/x-http-header-method-override-and-rest.html

While some Firewalls do not support PUT, DELETE or PATCH request, I would like to know what would the best way to implement it for requirements like this.

Best Regards, Josef

Hello Josef,

It can be implemented as a Router Wrapper. I can write a small builtin wrapper for that later on today.

Just to be clear on this @Dexus , you want something like this, right?:

app := iris.New()

app.Post("/path", func(ctx iris.Context){
    // handle post
   ctx.WriteString("post")
})

app.Delete("/path", func(ctx iris.Context){
    // handle DELETE or POST with X-HTTP-Method == 'DELETE'
    //  -> req.Method = DELETE
   ctx.WriteString("delete")
})

fetch("/path", {
    method: 'POST',
    headers: {
      "X-HTTP-Method": "DELETE"
    },
  })
  .then((resp)=>{
       //  resp == "delete" ? // <-------------
 })).catch(...)

That's exactly what I mean. I don't know if you can do the control via form field as well. In the past, with Nginx and Apache, I had both the header and the form variant (input called _method).
Thank you very much.

Nice! Don't worry, it will be based on the resources you posted above:

• form field
• url query
• header (x-http-method, x-method-override, x-http-method-override)
• custom getter

@Dexus it's done. Please test it in your app whenever you have time.

import "github.com/kataras/iris/middleware/methodoverride"

Test (&Example): https://github.com/kataras/iris/blob/master/middleware/methodoverride/methodoverride_test.go.

iris/middleware/methodoverride/methodoverride_test.go

Lines 12 to 26 in a14a345

	app := iris.New()
	mo := methodoverride.New(
	// Defaults to nil.
	//
	methodoverride.SaveOriginalMethod("_originalMethod"),
	// Default values.
	//
	// methodoverride.Methods(http.MethodPost),
	// methodoverride.Headers("X-HTTP-Method", "X-HTTP-Method-Override", "X-Method-Override"),
	// methodoverride.FormField("_method"),
	// methodoverride.Query("_method"),
	)
	// Register it with `WrapRouter`.
	app.WrapRouter(mo)

Override all default values with: methodoverride.New(methodoverride.Only(options...))

Works as expected and now makes it easier to use appropriate APIs under firewall fire. Thank you very much @kataras!

Nice! You are welcome @Dexus! I thank you for the feature request
