feat: change the type of Data in protobuf render for avoiding panic

Is your feature request related to a problem? Please describe.

hertz/pkg/app/server/render/protobuf.go

Lines 59 to 62 in 48fb76f

	bytes, err := proto.Marshal(r.Data.(proto.Message))
	if err != nil {
	return err
	}

r.Data is an empty interface object, panic occurs when r.Data doesn't implement proto.Message.

Describe the solution you'd like
Before:

hertz/pkg/app/server/render/protobuf.go

Lines 49 to 52 in 48fb76f

	// ProtoBuf contains the given interface object.
	type ProtoBuf struct {
	Data interface{}
	}

hertz/pkg/app/context.go

Lines 866 to 869 in 48fb76f

	// ProtoBuf serializes the given struct as ProtoBuf into the response body.
	func (ctx *RequestContext) ProtoBuf(code int, obj interface{}) {
	ctx.Render(code, render.ProtoBuf{Data: obj})
	}

After:

type ProtoBuf struct {
	Data proto.Message
}

func (ctx *RequestContext) ProtoBuf(code int, obj proto.Message) {
	ctx.Render(code, render.ProtoBuf{Data: obj})
}

Changing the type of Data in protobuf render directly is a solution. When obj doesn't implement proto.Message, compiling will failed. I think it is more useful to avoid panic in runtime.

Proposal: Add reload mechanism to html render

Describe the solution you'd like

Add or replace the way of rendering HTML in order to let the server reload HTML templates without restarting.

Describe alternatives you've considered

A timer or a file system watcher may help to decide whether to reload or not.

Additional context

Be aware of performance overhead. DO NOT reload it every time when render api is called.

		panic("can't find any http method")
	}
	for _, httpMethod := range httpMethods {
		if matches, err := regexp.MatchString("^[A-Z]+$", httpMethod); !matches || err != nil {

basic auth middleware example in cloudwego.io is not working

Describe the bug

basic-auth middleware example in cloudwego.io is not working.

When I tried to build for it, an error occured.

main.go:7:2: no required module provides package github.com/cloudwego/hertz/pkg/app/middlewares/basic_auth; to add it:

Then I found that required module should be github.com/cloudwego/hertz/pkg/app/middlewares/server/basic_auth instead of github.com/cloudwego/hertz/pkg/app/middlewares/basic_auth.

However, compile failed again when I solved the problem above.

Close connection after responding a short connection request (http1 case)

Is your feature request related to a problem? Please describe.

In #23, if http1 server does not close connection after responding the short connection request from ab(apache bench), ab will wait until timeout.

Describe the solution you'd like

A quick way to make it work is closing the connection from the server side.

Describe alternatives you've considered

Be careful about the error processing logic. Do not break any other rule other than this "short connection" case

Additional context

Before: Hertz assumes that the initiator of the short connection will actively disconnect the connection.

about Tracer add more simple demo or example

In addition, can you give an example that is more friendly to newbies and can be used out of the box, although there is an example in the hertz example, it does not meet the basic needs.
