[HTTP/3](https://en.wikipedia.org/wiki/HTTP/3) 是 Hypertext Transfer Protocol(HTTP) 的第三个主要版本。与依赖 TCP 的前辈不同HTTP/3 基于 [QUIC (Quick UDP Internet Connections) protocol](https://en.wikipedia.org/wiki/QUIC)。它带来了多项好处,减少了延迟并提高了性能:
* 实现不同网络连接之间的无缝过渡,例如从 Wi-Fi 切换到移动数据。
* 消除队头阻塞,以便丢失的数据包不会阻塞所有流。
* 在 TLS 握手的同时协商 TLS 版本,从而实现更快的连接。
* 默认提供加密,确保通过 HTTP/3 连接传输的所有数据都受到保护和保密。
* 在与客户端已建立连接的服务器通信时提供零往返时间 (0-RTT)。
APISIX 目前支持下游客户端和 APISIX 之间的 HTTP/3 连接。尚不支持与上游服务的 HTTP/3 连接。欢迎社区贡献。
:::caution
此功能尚未经过大规模测试,因此不建议用于生产使用。
:::
本文档将向您展示如何配置 APISIX 以在客户端和 APISIX 之间启用 HTTP/3 连接,并记录一些已知问题。
## 使用示例
### 启用 HTTP/3
将以下配置添加到 APISIX 的配置文件。该配置将在端口 `9443`(或其他端口)上启用 HTTP/3
```yaml title="config.yaml"
apisix:
ssl:
listen:
- port: 9443
enable_http3: true
ssl_protocols: TLSv1.3
```
:::info
如果您使用 Docker 部署 APISIX请确保在 HTTP3 端口中允许 UDP例如 `-p 9443:9443/udp`。
:::
然后重新加载 APISIX 以使配置更改生效:
```shell
apisix reload
```
### 生成证书和密钥
HTTP/3 需要 TLS。您可以利用购买的证书或自行生成证书。
如自行生成,首先生成证书颁发机构 (CA) 密钥和证书:
```shell
openssl genrsa -out ca.key 2048 && \
openssl req -new -sha256 -key ca.key -out ca.csr -subj "/CN=ROOTCA" && \
openssl x509 -req -days 36500 -sha256 -extensions v3_ca -signkey ca.key -in ca.csr -out ca.crt
```
接下来,生成具有 APISIX 通用名称的密钥和证书,并使用 CA 证书进行签名:
```shell
openssl genrsa -out server.key 2048 && \
openssl req -new -sha256 -key server.key -out server.csr -subj "/CN=test.com" && \
openssl x509 -req -days 36500 -sha256 -extensions v3_req \
-CA ca.crt -CAkey ca.key -CAserial ca.srl -CAcreateserial \
-in server.csr -out server.crt
```
### 配置 HTTPS
可选择性地将存储在 `server.crt` 和 `server.key` 中的内容加载到环境变量中:
```shell
server_cert=$(cat server.crt)
server_key=$(cat server.key)
```
创建一个保存服务器证书及其密钥的 SSL 对象:
```shell
curl -i "http://127.0.0.1:9180/apisix/admin/ssls" -X PUT -d '
{
"id": "quickstart-tls-client-ssl",
"sni": "test.com",
"cert": "'"${server_cert}"'",
"key": "'"${server_key}"'"
}'
```
### 创建路由
创建一个路由至 `httpbin.org`:
```shell
curl "http://127.0.0.1:9180/apisix/admin/routes" -X PUT -d '
{
"id":"httpbin-route",
"uri":"/get",
"upstream": {
"type":"roundrobin",
"nodes": {
"httpbin.org:80": 1
}
}
}'
```
### 验证 HTTP/3 连接
验证前需要安装支持 HTTP/3 的 curl如 [static-curl](https://github.com/stunnel/static-curl) 或其他支持 HTTP/3 的 curl。
发送一个请求到路由:
```shell
curl -kv --http3-only \
-H "Host: test.com" \
--resolve "test.com:9443:127.0.0.1" "https://test.com:9443/get"
```
应收到 `HTTP/3 200` 相应如下:
```text
* Added test.com:9443:127.0.0.1 to DNS cache
* Hostname test.com was found in DNS cache
* Trying 127.0.0.1:9443...

## 已知问题
- 对于 APISIX-3.9, Tongsuo 相关测试用例会失败,因为 Tongsuo 不支持 QUIC TLS。
- APISIX-3.9 基于 NGINX-1.25.3,存在 HTTP/3 漏洞CVE-2024-24989、CVE-2024-24990
