basic-auth
描述#
basic-auth 插件为消费者添加了基本访问身份验证,以便消费者在访问上游资源之前进行身份验证。
当消费者成功通过身份验证后,APISIX 会在将请求代理到上游服务之前向请求添加其他标头,例如 X-Consumer-Username、X-Credential-Identifier 和其他消费者自定义标头(如果已配置)。上游服务将能够区分消费者并根据需要实现其他逻辑。如果这些值中的任何一个不可用,则不会添加相应的标头。
属性#
消费者/凭证端:
| 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 |
|---|---|---|---|---|---|
| username | string | 是 | 消费者的唯一基本认证用户名。 | ||
| password | string | 是 | 消费者的基本认证密码。密码在存储到 etcd 之前会使用 AES 加密。你也可以将其存储在环境变量中并使用 env:// 前缀引用,或存储在 HashiCorp Vault 等密钥管理器中并使用 secret:// 前缀引用。 |
Route 端:
| 名称 | 类型 | 必选项 | 默认值 | 有效值 | 描述 |
|---|---|---|---|---|---|
| hide_credentials | boolean | 否 | false | 若为 true,则不将 Authorization 请求标头传递给上游服务。 | |
| anonymous_consumer | string | 否 | 匿名消费者名称。如果已配置,则允许匿名用户绕过身份验证。 | ||
| realm | string | 否 | basic | 在身份验证失败时,401 Unauthorized 响应中 WWW-Authenticate 标头的域值。该参数在 Apache APISIX 3.15.0 及以上版本中可用。 |
示例#
以下示例演示了如何在不同场景中使用 basic-auth 插件。
note
admin_key=$(yq '.deployment.admin.admin_key[0].key' conf/config.yaml | sed 's/"//g')
在路由上实现基本身份验证#
以下示例演示如何在路由上实现基本身份验证。
- Admin API
- ADC
- Ingress Controller
创建消费者 johndoe:
curl "http://127.0.0.1:9180/apisix/admin/consumers" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"username": "johndoe"
}'
为消费者创建 basic-auth 凭证:
curl "http://127.0.0.1:9180/apisix/admin/consumers/johndoe/credentials" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"id": "cred-john-basic-auth",
"plugins": {
"basic-auth": {
"username": "johndoe",
"password": "john-key"
}
}
}'
创建一个带有 basic-auth 的路由:
curl "http://127.0.0.1:9180/apisix/admin/routes" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"id": "basic-auth-route",
"uri": "/anything",
"plugins": {
"basic-auth": {}
},
"upstream": {
"type": "roundrobin",
"nodes": {
"httpbin.org:80": 1
}
}
}'
创建带有 basic-auth 凭证的消费者以及配置了 basic-auth 插件的路由:
consumers:
- username: johndoe

- name: basic-auth
type: basic-auth
config:
username: johndoe

使用有效凭证进行验证#
使用有效凭证发送请求:
curl -i "http://127.0.0.1:9080/anything" -u johndoe:john-key
你应该会看到类似于以下内容的 HTTP/1.1 200 OK 响应:
{
"args": {},
"headers": {
"Accept": "*/*",
"Authorization": "Basic am9obmRvZTpqb2huLWtleQ==",
"Host": "127.0.0.1",
"User-Agent": "curl/8.6.0",

},
"origin": "192.168.65.1, 205.198.122.37",
"url": "http://127.0.0.1/anything"
}
使用无效凭证进行验证#
使用无效凭证发送请求:
curl -i "http://127.0.0.1:9080/anything" -u johndoe:invalid-password
你应该看到以下 HTTP/1.1 401 Unauthorized 响应:
{"message":"Invalid user authorization"}
不使用凭证进行验证#
发送不携带凭证的请求:
curl -i "http://127.0.0.1:9080/anything"
你应该看到以下 HTTP/1.1 401 Unauthorized 响应:
{"message":"Missing authorization in request"}
隐藏上游的身份验证信息#
以下示例演示了如何通过配置 hide_credentials 来防止客户端凭证(Authorization 标头)被发送到上游服务。APISIX 默认情况下会将包含客户端凭证的 Authorization 标头转发到上游服务,这在某些情况下可能会导致安全风险,你应该考虑按本示例更新 hide_credentials。
- Admin API
- ADC
- Ingress Controller
创建消费者 johndoe:
curl "http://127.0.0.1:9180/apisix/admin/consumers" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"username": "johndoe"
}'
为消费者创建 basic-auth 凭证:
curl "http://127.0.0.1:9180/apisix/admin/consumers/johndoe/credentials" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"id": "cred-john-basic-auth",
"plugins": {
"basic-auth": {
"username": "johndoe",
"password": "john-key"
}
}
}'
不隐藏凭据#
使用 basic-auth 创建路由,并将 hide_credentials 配置为 false(默认配置):
curl "http://127.0.0.1:9180/apisix/admin/routes" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"id": "basic-auth-route",

"hide_credentials": false
}

将消费者自定义 ID 添加到标头#
以下示例演示了如何在 Consumer-Custom-Id 标头中将消费者自定义 ID 附加到经过身份验证的请求,该 ID 可用于根据需要实现其他逻辑。
- Admin API
- ADC
- Ingress Controller
创建带有自定义 ID 标签的消费者 johndoe:
curl "http://127.0.0.1:9180/apisix/admin/consumers" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"username": "johndoe",
"labels": {

}
}'
为消费者创建 basic-auth 凭证:
curl "http://127.0.0.1:9180/apisix/admin/consumers/johndoe/credentials" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"id": "cred-john-basic-auth",
"plugins": {
"basic-auth": {
"username": "johndoe",
"password": "john-key"
}
}
}'
创建一个带有 basic-auth 的路由:
curl "http://127.0.0.1:9180/apisix/admin/routes" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"id": "basic-auth-route",
"uri": "/anything",
"plugins": {
"basic-auth": {}
},
"upstream": {
"type": "roundrobin",
"nodes": {
"httpbin.org:80": 1
}
}
}'
创建带有 basic-auth 凭证的消费者以及启用 basic-auth 插件的路由:
consumers:
- username: johndoe
labels:
custom_id: "495aec6a"
credentials:
- name: basic-auth
type: basic-auth
config:
username: johndoe

plugins:
basic-auth: {}
upstream:

port: 80
weight: 1
将配置同步到网关:
adc sync -f adc.yaml
通过 Ingress Controller 配置资源时,目前不支持消费者自定义标签,请求中不会包含 X-Consumer-Custom-Id 标头。暂时无法通过 Ingress Controller 完成此示例。
使用有效凭证向路由发送请求进行验证:
curl -i "http://127.0.0.1:9080/anything" -u johndoe:john-key
你应该看到一个带有 X-Consumer-Custom-Id 的 HTTP/1.1 200 OK 响应,类似于以下内容:
{
"args": {},
"data": "",
"files": {},
"form": {},
"headers": {
"Accept": "*/*",
"Authorization": "Basic am9obmRvZTpqb2huLWtleQ==",
"Host": "127.0.0.1",
"User-Agent": "curl/8.6.0",
"X-Amzn-Trace-Id": "Root=1-66ea8d64-33df89052ae198a706e18c2a",
"X-Consumer-Username": "johndoe",
"X-Credential-Identifier": "cred-john-basic-auth",
"X-Consumer-Custom-Id": "495aec6a",
"X-Forwarded-Host": "127.0.0.1"
},
"json": null,
"method": "GET",
"origin": "192.168.65.1, 205.198.122.37",
"url": "http://127.0.0.1/anything"
}
匿名消费者的速率限制#
以下示例演示了如何为普通消费者和匿名消费者配置不同的速率限制策略,其中匿名消费者不需要进行身份验证,并且配额较少。
- Admin API
- ADC
- Ingress Controller
创建普通消费者 johndoe 并配置 limit-count 插件以允许 30 秒内的配额为 3:
curl "http://127.0.0.1:9180/apisix/admin/consumers" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"username": "johndoe",
"plugins": {
"limit-count": {
"count": 3,
"time_window": 30,
"rejected_code": 429,
"policy": "local"
}
}
}'
为消费者 johndoe 创建 basic-auth 凭证:
curl "http://127.0.0.1:9180/apisix/admin/consumers/johndoe/credentials" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"id": "cred-john-basic-auth",
"plugins": {
"basic-auth": {
"username": "johndoe",
"password": "john-key"
}
}
}'
创建匿名用户 anonymous,并配置 limit-count 插件,以允许 30 秒内配额为 1:
curl "http://127.0.0.1:9180/apisix/admin/consumers" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"username": "anonymous",
"plugins": {
"limit-count": {
"count": 1,
"time_window": 30,
"rejected_code": 429,
"policy": "local"
}
}
}'
创建一个路由并配置 basic-auth 插件来接受匿名消费者 anonymous 绕过身份验证:
curl "http://127.0.0.1:9180/apisix/admin/routes" -X PUT \
-H "X-API-KEY: ${admin_key}" \
-d '{
"id": "basic-auth-route",
"uri": "/anything",
"plugins": {
"basic-auth": {
"anonymous_consumer": "anonymous"
}
},
"upstream": {
"type": "roundrobin",
"nodes": {
"httpbin.org:80": 1
}
}
}'
配置具有不同速率限制的消费者以及接受匿名用户的路由:
consumers:
- username: johndoe
plugins:
limit-count:
count: 3
time_window: 30
rejected_code: 429

ApisixConsumer CRD 目前不支持在消费者上配置插件(authParameter 中允许的身份验证插件除外)。此示例无法通过 APISIX CRD 完成。
为了验证,请使用 johndoe 的凭证发送五个连续的请求:
resp=$(seq 5 | xargs -I{} curl "http://127.0.0.1:9080/anything" -u johndoe:john-key -o /dev/null -s -w "%{http_code}\n") && \
count_200=$(echo "$resp" | grep "200" | wc -l) && \
count_429=$(echo "$resp" | grep "429" | wc -l) && \
echo "200": $count_200, "429": $count_429
你应该看到以下响应,显示在 5 个请求中,3 个请求成功(状态代码 200),而其他请求被拒绝(状态代码 429)。
200: 3, 429: 2
发送五个匿名请求:
resp=$(seq 5 | xargs -I{} curl "http://127.0.0.1:9080/anything" -o /dev/null -s -w "%{http_code}\n") && \
count_200=$(echo "$resp" | grep "200" | wc -l) && \
count_429=$(echo "$resp" | grep "429" | wc -l) && \
echo "200": $count_200, "429": $count_429
你应该看到以下响应,表明只有一个请求成功:
200: 1, 429: 4
