| ## 描述 |
| |
| `jwe-decrypt` 插件,用于解密 APISIX [Service](../terminology/service.md) 或者 [Route](../terminology/route.md) 请求中的 [JWE](https://datatracker.ietf.org/doc/html/rfc7516) 授权请求头。 |
| |
| 插件增加了一个 `/apisix/plugin/jwe/encrypt` 的内部 API,提供给 JWE 加密使用。解密时,秘钥应该配置在 [Consumer](../terminology/consumer.md)内。 |
| |
| ## 属性 |
| |
| Consumer 配置: |
| |
| | 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 | |
| |---------------|---------|-------|-------|-----|-------------------------------------------------------------| |
| | key | string | True | | | Consumer 的唯一 key | |
| | secret | string | True | | | 解密密钥,必须为 32 位。秘钥可以使用 [Secret](../terminology/secret.md) 资源保存在密钥管理服务中 | |
| | is_base64_encoded | boolean | False | false | | 如果密钥是 Base64 编码,则需要配置为 `true` | |
| |
| :::note |
| |
| 注意,在启用 `is_base64_encoded` 后,你的 `secret` 长度可能会超过 32 位,你只需要保证在 Decode 后的长度仍然是 32 位即可。 |
| |
| ::: |
| |
| Route 配置: |
| |
| | 名称 | 类型 | 必选项 | 默认值 | 描述 | |
| |----------------|---------|-------|---------------|----------------------------------------------------------------------------| |
| | header | string | True | Authorization | 指定请求头,用于获取加密令牌 | |
| | forward_header | string | True | Authorization | 传递给 Upstream 的请求头名称 | |
| | strict | boolean | False | true | 如果为配置为 true,请求中缺失 JWE token 则抛出 `403` 异常。如果为 `false`, 在缺失 JWE token 的情况下不会抛出异常 | |
| |
| ## 启用插件 |
| |
| 首先,基于 `jwe-decrypt` 插件创建一个 Consumer,并且配置解密密钥: |
| |
| :::note |
| |
| 您可以这样从 `config.yaml` 中获取 `admin_key` 并存入环境变量: |
| |
| ```bash |
| admin_key=$(yq '.deployment.admin.admin_key[0].key' conf/config.yaml | sed 's/"//g') |
| ``` |
| |
| ::: |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/consumers -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "username": "jack", |
| "plugins": { |
| "jwe-decrypt": { |
| "key": "user-key", |
| "secret": "-secret-length-must-be-32-chars-" |
| } |
| } |
| }' |
| ``` |
| |
| 下一步,基于 `jwe-decrypt` 插件创建一个路由,用于解密 authorization 请求头: |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/routes/1 -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "methods": ["GET"], |
| "uri": "/anything*", |
| "plugins": { |
| "jwe-decrypt": {} |
| }, |
| "upstream": { |
| "type": "roundrobin", |
| "nodes": { |
| "httpbin.org:80": 1 |
| } |
| } |
| }' |
| ``` |
| |
| ### 使用 JWE 加密数据 |
| |
| 该插件创建了一个内部的 API `/apisix/plugin/jwe/encrypt` 以使用 JWE 进行加密。要公开它,需要创建一个对应的路由,并启用 [public-api](public-api.md) 插件: |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/routes/jwenew -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "uri": "/apisix/plugin/jwe/encrypt", |
| "plugins": { |
| "public-api": {} |
| } |
| }' |
| ``` |
| |
| 向 API 发送一个请求,将 Consumer 中配置的密钥,以参数的方式传递给 URI,用于加密 payload 中的一些数据。 |
| |
| ```shell |
| curl -G --data-urlencode 'payload={"uid":10000,"uname":"test"}' 'http://127.0.0.1:9080/apisix/plugin/jwe/encrypt?key=user-key' -i |
| ``` |
| |
| 您应该看到类似于如下内容的响应结果,其中 JWE 加密的数据位于响应体中: |
| |
| ``` |
| HTTP/1.1 200 OK |
| Date: Mon, 25 Sep 2023 02:38:16 GMT |
| Content-Type: text/plain; charset=utf-8 |
| Transfer-Encoding: chunked |
| Connection: keep-alive |
| Server: APISIX/3.5.0 |
| Apisix-Plugins: public-api |
| |
| eyJhbGciOiJkaXIiLCJraWQiOiJ1c2VyLWtleSIsImVuYyI6IkEyNTZHQ00ifQ..MTIzNDU2Nzg5MDEy.hfzMJ0YfmbMcJ0ojgv4PYAHxPjlgMivmv35MiA.7nilnBt2dxLR_O6kf-HQUA |
| ``` |
| |
| ### 使用 JWE 解密数据 |
| |
| 将加密数据放在 `Authorization` 请求头中,向 API 发起请求: |
| |
| ```shell |
| curl http://127.0.0.1:9080/anything/hello -H 'Authorization: eyJhbGciOiJkaXIiLCJraWQiOiJ1c2VyLWtleSIsImVuYyI6IkEyNTZHQ00ifQ..MTIzNDU2Nzg5MDEy.hfzMJ0YfmbMcJ0ojgv4PYAHxPjlgMivmv35MiA.7nilnBt2dxLR_O6kf-HQUA' -i |
| ``` |
| |
| 您应该可以看到类似于如下的响应内容,其中 `Authorization` 响应头显示了有效的解密内容: |
| |
| ``` |
| HTTP/1.1 200 OK |
| Content-Type: application/json |
| Content-Length: 452 |
| Connection: keep-alive |
| Date: Mon, 25 Sep 2023 02:38:59 GMT |
| Access-Control-Allow-Origin: * |
| Access-Control-Allow-Credentials: true |
| Server: APISIX/3.5.0 |
| Apisix-Plugins: jwe-decrypt |
| |
| { |
| "args": {}, |
| "data": "", |
| "files": {}, |
| "form": {}, |
| "headers": { |
| "Accept": "*/*", |
| "Authorization": "{\"uid\":10000,\"uname\":\"test\"}", |
| "Host": "127.0.0.1", |
| "User-Agent": "curl/8.1.2", |
| "X-Amzn-Trace-Id": "Root=1-6510f2c3-1586ec011a22b5094dbe1896", |
| "X-Forwarded-Host": "127.0.0.1" |
| }, |
| "json": null, |
| "method": "GET", |
| "origin": "127.0.0.1, 119.143.79.94", |
| "url": "http://127.0.0.1/anything/hello" |
| } |
| ``` |
| |
| ## 删除插件 |
| |
| 要删除 `jwe-decrypt` 插件,您可以从插件配置中删除插件对应的 JSON 配置,APISIX 会自动加载,您不需要重新启动即可生效。 |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/routes/1 -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "methods": ["GET"], |
| "uri": "/anything*", |
| "plugins": {}, |
| "upstream": { |
| "type": "roundrobin", |
| "nodes": { |
| "httpbin.org:80": 1 |
| } |
| } |
| }' |
| ``` |
