| ## 描述 |
| |
| Credential 是存放 [Consumer](./consumer.md) 凭证配置的对象。 |
| 一个 Consumer 可以使用不同类型的多个凭证。 |
| 当你需要为一个 Consumer 配置不同类型的多个凭证时,就会用到 Credential。 |
| |
| 目前,Credential 可以配置的身份认证插件包括 `basic-auth`、`hmac-auth`、`jwt-auth` 以及 `key-auth`。 |
| |
| ## 配置选项 |
| |
| 定义 Credential 的字段如下: |
| |
| | 名称 | 必选项 | 描述 | |
| |---------|-----|-----------------------------------------------------| |
| | desc | 否 | Credential 描述。 | |
| | labels | 否 | Credential 标签。 | |
| | plugins | 否 | Credential 对应的插件配置。详细信息,请参考 [Plugins](./plugin.md)。 | |
| |
| :::note |
| |
| 如需了解更多关于 Credential 对象的信息,你可以参考 [Admin API Credential](../admin-api.md#credential) 资源介绍。 |
| |
| ::: |
| |
| ## 使用示例 |
| |
| [Consumer 使用示例](./consumer.md#使用示例) 介绍了如何对 Consumer 配置认证插件,并介绍了如何配合其他插件使用。 |
| 在该示例中,该 Consumer 只有一个 key-auth 类型的凭证。 |
| 现在假设用户需要为该 Consumer 配置多个凭证,你可以使用 Credential 来支持这一点。 |
| |
| :::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') |
| ``` |
| |
| ::: |
| |
| 1. 创建 Consumer。不指定认证插件,而是稍后使用 Credential 来配置认证插件。 |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/consumers \ |
| -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "username": "jack" |
| }' |
| ``` |
| |
| 2. 为 Consumer 配置 2 个 启用 `key-auth` 的 Credential。 |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/consumers/jack/credentials/key-auth-one \ |
| -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "plugins": { |
| "key-auth": { |
| "key": "auth-one" |
| } |
| } |
| }' |
| ``` |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/consumers/jack/credentials/key-auth-two \ |
| -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "plugins": { |
| "key-auth": { |
| "key": "auth-two" |
| } |
| } |
| }' |
| ``` |
| |
| 3. 创建路由,设置路由规则和启用插件配置。 |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/routes/1 \ |
| -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "plugins": { |
| "key-auth": {} |
| }, |
| "upstream": { |
| "nodes": { |
| "127.0.0.1:1980": 1 |
| }, |
| "type": "roundrobin" |
| }, |
| "uri": "/hello" |
| }' |
| ``` |
| |
| 4. 测试插件 |
| |
| 分别使用 `auth-one` 和 `auth-two` 两个 key 来测试请求,都响应正常。 |
| |
| ```shell |
| curl http://127.0.0.1:9080/hello -H 'apikey: auth-one' -I |
| curl http://127.0.0.1:9080/hello -H 'apikey: auth-two' -I |
| ``` |
| |
| 为该 Consumer 启用 `limit-count` 插件。 |
| |
| ```shell |
| curl http://127.0.0.1:9180/apisix/admin/consumers \ |
| -H "X-API-KEY: $admin_key" -X PUT -d ' |
| { |
| "username": "jack", |
| "plugins": { |
| "limit-count": { |
| "count": 2, |
| "time_window": 60, |
| "rejected_code": 503, |
| "key": "remote_addr" |
| } |
| } |
| }' |
| ``` |
| |
| 分别使用这两个 key 连续 3 次以上请求该路由,测试返回 `503`,请求被限制。 |
