golangで作るQUICプロトコル(HTTP3リクエストの送信と受信)
はじめに
前回までの記事でQUICプロトコル上でTLS1.3のハンドシェイクが完了しました。
TLS1.3のハンドシェイクが完了したということは、Application Data=HTTPとかをサーバとやり取りできるということになります。
今回はサーバにHTTP3のリクエストを送り、メッセージを受信してみます。
ソースは以下にあります。
HTTP2とHTTP3
HTTP2からストリームとフレームという仕組みが用いられて、1つのTCPコネクションがストリームとなり、
ストリーム内で複数のフレームがHTTPヘッダやデータとしてやり取りされます。
HTTP2とHTTP3で大きく仕組みに違いはありません。
※ちゃんとRFC読んでないですがたぶん、hpackがqpackになったりプライオリティが廃止されたりとか？
ASCII文字の圧縮と展開はHTTP2と同じHuffmanテーブルを利用するので同じです。
以前にHTTP2プロトコルを作成していたので、Huffmanエンコードとデコードは以前の実装をそのまま使ってます。
HTTP3のヘッダはHTTP2のhpackではなく、QPACK: Field Compression for HTTP/3としてRFC9204で再設計されました。
つまりHTTP3のヘッダはqpackで作成しないといけないので、まずqpackを実装する必要があります。
qpackの実装
qpackにはhpackと同様に静的テーブルと動的テーブルがあります。
静的テーブルはRFCのAppendix A. Static Tableにある0〜98のものです。
この静的テーブルにない独自のヘッダを使用したい場合は、動的テーブルにヘッダと値をセットします。
サーバにGETを送るだけなら静的テーブルだけで事足りるので、動的テーブルの仕組みは解説しません。
というか実装してないのでわかっていません、どなたか教えてください。
とりあえず静的テーブルを↓のように配列で持ちます。
type Http3Header struct {
Name string
Value string
}
var Http3StaticTable = []Http3Header{
{Name: ":authority"},
{Name: ":path", Value: "/"},
~省略~
{Name: "x-forwarded-for"},
{Name: "x-frame-options", Value: "deny"},
{Name: "x-frame-options", Value: "sameorigin"},
}
静的テーブルを参照してヘッダを作る関数です。
NewHttp3Headerにはヘッダのnameとvalueを渡してテーブルを検索します。
func NewHttp3Header(name, value string) (headerByte []byte) {
index, staticval := getHttp3HeaderIndexByNameAndValue(name, value)
if staticval {
/*
0 1 2 3 4 5 6 7
+---+---+---+---+---+---+---+---+
| 1 | T | Index (6+) |
+---+---+-----------------------+
*/
headerVal, _ := strconv.ParseUint(fmt.Sprintf("11%06b", index), 2, 8)
headerByte = append(headerByte, byte(headerVal))
} else {
/*
0 1 2 3 4 5 6 7
+---+---+---+---+---+---+---+---+
| 0 | 1 | N | T |Name Index (4+)|
+---+---+---+---+---------------+
| H | Value Length (7+) |
+---+---------------------------+
| Value String (Length bytes) |
+-------------------------------+
*/
var headerIndex uint64
// 15以下なら
if index <= 15 {
// Name Indexの前の先頭4bitは0101で固定
headerIndex, _ = strconv.ParseUint(fmt.Sprintf("0101%04b", index), 2, 8)
headerByte = append(headerByte, byte(headerIndex))
} else {
// Name Indexの前の先頭4bitは0101で固定
headerIndex, _ = strconv.ParseUint(fmt.Sprintf("0101%04b", 15), 2, 8)
index -= 15
headerByte = append(headerByte, byte(headerIndex))
headerIndex, _ = strconv.ParseUint(fmt.Sprintf("%08b", index), 2, 8)
headerByte = append(headerByte, byte(headerIndex))
}
// 文字列をHuffuman Encodeする
encodeVal := HuffmanEncode(value)
headerVal, _ := strconv.ParseUint(fmt.Sprintf("1%07b", len(encodeVal)), 2, 8)
headerByte = append(headerByte, byte(headerVal))
headerByte = append(headerByte, encodeVal...)
}
fmt.Printf("Name is %s, Values is %s, byte is %x\n", name, value, headerByte)
return headerByte
}
静的テーブル見てもらえばわかるように、valueの値が固定のになるものと任意の値が入るものがあります。
例えば index=17 の:methodはvalueが固定なのでindexの17だけ送れば、静的テーブルを参照してGETとわかるのでわざわざ文字を送る必要はありません。
index=0 の:autorityはサーバのアドレスをセットするのですが(HTTP1.1でいうHostヘッダ)、サーバのアドレスは127.0.0.1だったりgoogle.comだったりと値はいろいろ異なります。
index=17の:method GETを送りたい場合は、4.5.2. Indexed Field Lineを使用します。
0 1 2 3 4 5 6 7
+---+---+---+---+---+---+---+---+
| 1 | T | Index (6+) |
+---+---+-----------------------+
1bit目のTは静的テーブルなら1、動的テーブルなら0が入ります。
3~7bitでindexを表すので、index=17を2進数にして当てはめると以下のようになります。
0 1 2 3 4 5 6 7
+---+---+---+---+---+---+---+---+
| 1 | T | Index (6+) |
+---+---+-----------------------+
| 1 | 1 | 0 | 1 | 0 | 0 | 0 | 1 | → D1
+---+---+-----------------------+
11010001を16進数にするとD1になるので、index=17の:method GETはD1になります。
固定値ではなく任意の値、例えばindex=0 の:autorityで127.0.0.1:18843を送るときは、4.5.4. Literal Field Line with Name Referenceを使います。
0 1 2 3 4 5 6 7
+---+---+---+---+---+---+---+---+
| 0 | 1 | N | T |Name Index (4+)|
+---+---+---+---+---------------+
| H | Value Length (7+) |
+---+---------------------------+
| Value String (Length bytes) |
+-------------------------------+
index=0 の:autorityで127.0.0.1:18843で↑を当てはめると以下のようになります。
2byte目の0bitにHuffmanエンコードしていることを表す1のフラグが立ち、1~7bit目にLengthが入ります。
3byte目以後にエンコードした127.0.0.1:18843をセットします。
0 1 2 3 4 5 6 7
+---+---+---+---+---+---+---+---+
| 0 | 1 | 0 | 1 | 0 | 0 | 0 | 0 | → 50
+---+---+---+---+---------------+
| 1 | 0 | 0 | 0 | 1 | 0 | 1 | 1 | → 8b
+---+---------------------------+
| Huffmanエンコードした127.0.0.1:18843 → 089d5c0b8170dc0bcd34cf
+-------------------------------+
なので:autorityで127.0.0.1:18843は508b089d5c0b8170dc0bcd34cfになります。
文字のHuffmanエンコード・デコードはHTTP2を作った時の実装をそのまま使っているので、知りたいかたはそちらを見てください。
HTTP3リクエストの送信
前回の記事でHandshake Doneを受信するとこまで説明しているので、続きから解説します。
STREAMフレームを入れたShort Header Packetを作成して送信します。
shortByte := short.CreateShortHeaderPacket(tlsinfo, quic.NewControlStream())
tlsinfo.QPacketInfo.ShortHeaderPacketNumber++
parsed, recvPacket = quic.SendQuicPacket(conn, [][]byte{shortByte}, tlsinfo)
//fmt.Printf("recv http3 setting packet is %x\n", recvPacket)
if len(recvPacket) == 0 {
fmt.Println("all packet is parsed")
short = parsed.Packet.(quic.ShortHeader)
}
frames = short.ToPlainQuicPacket(short, tlsinfo)
for _, v := range frames {
fmt.Printf("frames is %+v\n", v)
}
19.8. STREAM Framesは以下のフォーマットです。
Short Header PacketでApplication Dataのやり取りに使うフレームです。
Stream DataにHTTP3のデータが入ります。
STREAM Frame {
Type (i) = 0x08..0x0f,
Stream ID (i),
[Offset (i)],
[Length (i)],
Stream Data (..),
}
キャプチャしたパケットを見るとまずクライアントはサーバに、SETTINGSフレームを送っているので同じようにします。
STREAMフレームのデータに000400をセットします。
※STREAMフレームにセットされたHTTP3のSETTINGS
STREAMフレームを作成したら、フレームを暗号化してからヘッダを保護してサーバに送信します。
フレームの暗号化とヘッダ保護はLong Header Packetとやり方は同じで前回までの記事で説明しているので、割愛します。
func NewControlStream() (data []byte) {
// Stream Type : HTTP3 Control Stream
data = []byte{0x00}
// Type : HTTP3 Settings
data = append(data, 0x04)
// set Length
data = append(data, 0x00)
// Stream Frame にセット
stream := StreamFrame{
Type: []byte{0x08},
StreamID: []byte{0x02},
StreamData: data,
}
return toByteArr(stream)
}
サーバにHTTP3のSETTINGSフレームを送ったら、サーバにリクエストを送信します。
NewHttp3RequestでSTREAMフレームのデータにHTTP3のリクエストをセットします。
func NewHttp3Request() (data []byte) {
// Stream Type : Control Stream
header := CreateHTTP3HeaderByteArray()
// Type : Header
data = append(data, 0x01)
// set Length
data = append(data, byte(len(header)))
// set header data
data = append(data, header...)
// Stream Frame にセット
// 最下位BitのFINビット=1で送るのでTypeは9
stream := StreamFrame{
Type: []byte{0x09},
StreamID: []byte{0x00},
StreamData: data,
}
return toByteArr(stream)
}
ヘッダの作成では以下のような値をセットしてます。
authorityが固定値なのはまぁダメですけどね笑
func CreateHTTP3HeaderByteArray() []byte {
header := []byte{0x00, 0x00}
header = append(header, NewHttp3Header(":authority", "127.0.0.1:18443")...)
header = append(header, NewHttp3Header(":method", "GET")...)
header = append(header, NewHttp3Header(":path", "/")...)
header = append(header, NewHttp3Header(":scheme", "https")...)
header = append(header, NewHttp3Header("accept-encoding", "gzip")...)
header = append(header, NewHttp3Header("user-agent", "quic-go HTTP/3")...)
return header
}
リクエストが出来たら暗号化してサーバに送信します。
h3request := short.CreateShortHeaderPacket(tlsinfo, quic.NewHttp3Request())
parsed, recvPacket = quic.SendQuicPacket(conn, [][]byte{h3request}, tlsinfo)
if len(recvPacket) == 0 {
fmt.Println("all packet is parsed")
short = parsed.Packet.(quic.ShortHeader)
}
frames = short.ToPlainQuicPacket(short, tlsinfo)
for _, v := range frames {
fmt.Printf("frames is %+v\n", v)
}
サーバからデータが返ってくるので複合してからQUICのフレームとしてパースします。
パースしたSTREAMSフレームのデータにHTTP3のフレームが入っているので、DATAフレームからサーバのメッセージを読み取ります。
parsed, recvPacket = quic.ReadNextPacket(conn, tlsinfo)
if len(recvPacket) == 0 {
fmt.Println("all packet is parsed")
short = parsed.Packet.(quic.ShortHeader)
}
frames = short.ToPlainQuicPacket(short, tlsinfo)
for _, v := range frames {
fmt.Printf("HTTP3 Header frames is %+v\n", v)
}
stream := frames[1].(quic.StreamFrame)
fmt.Printf("frame %+v\n", stream)
h3data := quic.ParseHTTP3(stream.StreamData)
fmt.Printf("message from http3 server is %s\n", h3data[1].Payload)
これで処理は終わりです。
quic-goのサーバにクライアント側のコードを実行してみます。

message from server : hello from quic-go HTTP3 server !!
ちゃんとサーバからメッセージを受信しました。
おわりに
というわけで自作したQUICプロトコル上で、自作したHTTP3を動かしてみました。
コードはぐちゃぐちゃですし、quic-go以外の実装のサーバには試してないので、たぶん動かないでしょうw
QUICがUDP上で信頼性を保つための仕組み、ACKフレームもちゃんとサーバに送り返していません(手抜き)
Ethernetからいろいろと作り始めてQUIC,HTTP3まで来たのはなかなか感慨深いものがありますね〜
RFCやgoのソースを読むのが苦ではなくなりましたし(相変わらず書けはしないのですが...)、自作プロトコルのコードが動いたときの喜びといったらね。
自作OS,自作キーボードなど流行っていますが、僕は自作プロトコルスタック推していきたいですね。
TCPIPとかTLSとか作っているので、よかったらご笑覧ください。
