# 閘道規則 API 範例
下列範例示範如何使用 CLI 和 AWS Python SDK (Boto3) AWS 管理閘道規則。
## 建立具有靜態組態套件覆寫的規則
下列範例會建立將特定 IAM 主體繫結至組態套件版本的規則。使用此方法來進行 QA 或偵錯。
**Example**
1. 執行以下命令：
```
aws bedrock-agentcore-control create-gateway-rule \
--gateway-identifier my-gateway-abc1234567 \
--priority 100 \
--description "Pin QA role to bundle version" \
--conditions '[
{
"matchPrincipals": {
"anyOf": [
{
"iamPrincipal": {
"arn": "arn:aws:iam::123456789012:role/QARole",
"operator": "StringEquals"
}
}
]
}
}
]' \
--actions '[
{
"configurationBundle": {
"staticOverride": {
"bundleArn": "arn:aws:bedrock-agentcore:us-west-2:123456789012:configuration-bundle/myBundle-abc1234567",
"bundleVersion": "1234abcd-12ab-34cd-56ef-1234567890ab"
}
}
}
]'
```
1.
```
import boto3
client = boto3.client("bedrock-agentcore-control", region_name="us-west-2")
response = client.create_gateway_rule(
gatewayIdentifier="my-gateway-abc1234567",
priority=100,
description="Pin QA role to bundle version",
conditions=[
{
"matchPrincipals": {
"anyOf": [
{
"iamPrincipal": {
"arn": "arn:aws:iam::123456789012:role/QARole",
"operator": "StringEquals",
}
}
]
}
}
],
actions=[
{
"configurationBundle": {
"staticOverride": {
"bundleArn": "arn:aws:bedrock-agentcore:us-west-2:123456789012:configuration-bundle/myBundle-abc1234567",
"bundleVersion": "1234abcd-12ab-34cd-56ef-1234567890ab",
}
}
}
],
)
print(f"Rule ID: {response['ruleId']}")
```
## 建立全部擷取的預設規則
下列範例會建立沒有條件的規則。此規則符合所有流量，並做為預設值。指派高優先順序號碼，讓更具體的規則優先。
**Example**
1. 執行以下命令：
```
aws bedrock-agentcore-control create-gateway-rule \
--gateway-identifier my-gateway-abc1234567 \
--priority 1000000 \
--description "Default configuration bundle for all traffic" \
--actions '[
{
"configurationBundle": {
"staticOverride": {
"bundleArn": "arn:aws:bedrock-agentcore:us-west-2:123456789012:configuration-bundle/myBundle-abc1234567",
"bundleVersion": "1234abcd-12ab-34cd-56ef-1234567890ab"
}
}
}
]'
```
1.
```
import boto3
client = boto3.client("bedrock-agentcore-control", region_name="us-west-2")
response = client.create_gateway_rule(
gatewayIdentifier="my-gateway-abc1234567",
priority=1000000,
description="Default configuration bundle for all traffic",
actions=[
{
"configurationBundle": {
"staticOverride": {
"bundleArn": "arn:aws:bedrock-agentcore:us-west-2:123456789012:configuration-bundle/myBundle-abc1234567",
"bundleVersion": "1234abcd-12ab-34cd-56ef-1234567890ab",
}
}
}
],
)
print(f"Rule ID: {response['ruleId']}")
```
## 建立具有加權組態套件分割的規則
下列範例會建立規則，以分割兩個組態套件版本之間的流量，以進行 A/B 測試。在此範例中，80% 的流量使用變體 A，20% 使用變體 B。
**Example**
1. 執行以下命令：
```
aws bedrock-agentcore-control create-gateway-rule \
--gateway-identifier my-gateway-abc1234567 \
--priority 500 \
--description "A/B test: 80/20 traffic split" \
--actions '[
{
"configurationBundle": {
"weightedOverride": {
"trafficSplit": [
{
"name": "variant-a",
"weight": 80,
"configurationBundle": {
"bundleArn": "arn:aws:bedrock-agentcore:us-west-2:123456789012:configuration-bundle/myBundle-abc1234567",
"bundleVersion": "1234abcd-12ab-34cd-56ef-1234567890ab"
},
"description": "Control variant"
},
{
"name": "variant-b",
"weight": 20,
"configurationBundle": {
"bundleArn": "arn:aws:bedrock-agentcore:us-west-2:123456789012:configuration-bundle/myBundle-abc1234567",
"bundleVersion": "12345678-1234-5678-9abc-123456789012"
},
"description": "Treatment variant"
}
]
}
}
}
]'
```
1.
```
import boto3
client = boto3.client("bedrock-agentcore-control", region_name="us-west-2")
response = client.create_gateway_rule(
gatewayIdentifier="my-gateway-abc1234567",
priority=500,
description="A/B test: 80/20 traffic split",
actions=[
{
"configurationBundle": {
"weightedOverride": {
"trafficSplit": [
{
"name": "variant-a",
"weight": 80,
"configurationBundle": {
"bundleArn": "arn:aws:bedrock-agentcore:us-west-2:123456789012:configuration-bundle/myBundle-abc1234567",
"bundleVersion": "1234abcd-12ab-34cd-56ef-1234567890ab",
},
"description": "Control variant",
},
{
"name": "variant-b",
"weight": 20,
"configurationBundle": {
"bundleArn": "arn:aws:bedrock-agentcore:us-west-2:123456789012:configuration-bundle/myBundle-abc1234567",
"bundleVersion": "12345678-1234-5678-9abc-123456789012",
},
"description": "Treatment variant",
},
]
}
}
}
],
)
print(f"Rule ID: {response['ruleId']}")
```
**注意**
若要在 A/B 測試期間維持一致的使用者體驗，請在閘道調用請求中包含 `X-Amzn-Bedrock-AgentCore-Runtime-Session-Id`標頭。如需詳細資訊，請參閱[加權規則的工作階段黏性](gateway-rules-session-stickiness.md)。
## 建立具有目標路由的規則
下列範例會建立規則，將符合特定路徑模式的請求路由至目標。
**Example**
1. 執行以下命令：
```
aws bedrock-agentcore-control create-gateway-rule \
--gateway-identifier my-gateway-abc1234567 \
--priority 150 \
--description "Route /my-target-canary requests to canary target" \
--conditions '[
{
"matchPaths": {
"anyOf": [
"/my-target-canary/*"
]
}
}
]' \
--actions '[
{
"routeToTarget": {
"staticRoute": {
"targetName": "my-target-canary"
}
}
}
]'
```
1.
```
import boto3
client = boto3.client("bedrock-agentcore-control", region_name="us-west-2")
response = client.create_gateway_rule(
gatewayIdentifier="my-gateway-abc1234567",
priority=150,
description="Route /my-target-canary requests to canary target",
conditions=[
{
"matchPaths": {
"anyOf": ["/my-target-canary/*"]
}
}
],
actions=[
{
"routeToTarget": {
"staticRoute": {
"targetName": "my-target-canary",
}
}
}
],
)
print(f"Rule ID: {response['ruleId']}")
```
## 建立具有加權目標路由的規則
下列範例會建立在兩個目標之間分割流量的規則。在此範例中，90% 的流量路由至主要目標，10% 的流量路由至 Canary 目標。
**Example**
1. 執行以下命令：
```
aws bedrock-agentcore-control create-gateway-rule \
--gateway-identifier my-gateway-abc1234567 \
--priority 300 \
--description "Canary deployment: 90/10 target split" \
--actions '[
{
"routeToTarget": {
"weightedRoute": {
"trafficSplit": [
{
"name": "primary",
"weight": 90,
"targetName": "my-target-primary",
"description": "Primary target"
},
{
"name": "canary",
"weight": 10,
"targetName": "my-target-canary",
"description": "Canary target"
}
]
}
}
}
]'
```
1.
```
import boto3
client = boto3.client("bedrock-agentcore-control", region_name="us-west-2")
response = client.create_gateway_rule(
gatewayIdentifier="my-gateway-abc1234567",
priority=300,
description="Canary deployment: 90/10 target split",
actions=[
{
"routeToTarget": {
"weightedRoute": {
"trafficSplit": [
{
"name": "primary",
"weight": 90,
"targetName": "my-target-primary",
"description": "Primary target",
},
{
"name": "canary",
"weight": 10,
"targetName": "my-target-canary",
"description": "Canary target",
},
]
}
}
}
],
)
print(f"Rule ID: {response['ruleId']}")
```
## 建立具有合併條件和動作的規則
下列範例會建立同時具有條件類型和動作類型的規則。請求必須至少符合每個條件類型的一個項目 （跨類型AND 邏輯）。
**Example**
1. 執行以下命令：
```
aws bedrock-agentcore-control create-gateway-rule \
--gateway-identifier my-gateway-abc1234567 \
--priority 50 \
--description "QA role on /my-target-canary paths: pin bundle and route to canary" \
--conditions '[
{
"matchPrincipals": {
"anyOf": [
{
"iamPrincipal": {
"arn": "arn:aws:iam::123456789012:role/QARole",
"operator": "StringEquals"
}
}
]
}
},
{
"matchPaths": {
"anyOf": [
"/my-target-canary/*"
]
}
}
]' \
--actions '[
{
"configurationBundle": {
"staticOverride": {
"bundleArn": "arn:aws:bedrock-agentcore:us-west-2:123456789012:configuration-bundle/myBundle-abc1234567",
"bundleVersion": "1234abcd-12ab-34cd-56ef-1234567890ab"
}
}
},
{
"routeToTarget": {
"staticRoute": {
"targetName": "my-target-canary"
}
}
}
]'
```
1.
```
import boto3
client = boto3.client("bedrock-agentcore-control", region_name="us-west-2")
response = client.create_gateway_rule(
gatewayIdentifier="my-gateway-abc1234567",
priority=50,
description="QA role on /my-target-canary paths: pin bundle and route to canary",
conditions=[
{
"matchPrincipals": {
"anyOf": [
{
"iamPrincipal": {
"arn": "arn:aws:iam::123456789012:role/QARole",
"operator": "StringEquals",
}
}
]
}
},
{
"matchPaths": {
"anyOf": ["/my-target-canary/*"]
},
},
],
actions=[
{
"configurationBundle": {
"staticOverride": {
"bundleArn": "arn:aws:bedrock-agentcore:us-west-2:123456789012:configuration-bundle/myBundle-abc1234567",
"bundleVersion": "1234abcd-12ab-34cd-56ef-1234567890ab",
}
}
},
{
"routeToTarget": {
"staticRoute": {
"targetName": "my-target-canary",
}
}
},
],
)
print(f"Rule ID: {response['ruleId']}")
```
**注意**
此規則只有在發起人是 QA 角色且請求路徑符合 時才會相符`/my-target-canary/*`。必須滿足這兩個條件。
## 取得閘道規則
下列範例會擷取特定閘道規則的詳細資訊。
**Example**
1. 執行以下命令：
```
aws bedrock-agentcore-control get-gateway-rule \
--gateway-identifier my-gateway-abc1234567 \
--rule-id 12345678-1234-1234-1234-123456789012
```
1.
```
import boto3
client = boto3.client("bedrock-agentcore-control", region_name="us-west-2")
response = client.get_gateway_rule(
gatewayIdentifier="my-gateway-abc1234567",
ruleId="12345678-1234-1234-1234-123456789012",
)
print(f"Priority: {response['priority']}")
print(f"Status: {response['status']}")
print(f"Actions: {response['actions']}")
```
## 更新閘道規則
下列範例會更新現有閘道規則的優先順序和描述。
**Example**
1. 執行以下命令：
```
aws bedrock-agentcore-control update-gateway-rule \
--gateway-identifier my-gateway-abc1234567 \
--rule-id 12345678-1234-1234-1234-123456789012 \
--priority 200 \
--description "Updated priority for QA rule"
```
1.
```
import boto3
client = boto3.client("bedrock-agentcore-control", region_name="us-west-2")
response = client.update_gateway_rule(
gatewayIdentifier="my-gateway-abc1234567",
ruleId="12345678-1234-1234-1234-123456789012",
priority=200,
description="Updated priority for QA rule",
)
print(f"Status: {response['status']}")
```
## 列出閘道規則
下列範例列出閘道的所有規則。結果會依優先順序遞增排序。
**Example**
1. 執行以下命令：
```
aws bedrock-agentcore-control list-gateway-rules \
--gateway-identifier my-gateway-abc1234567
```
1.
```
import boto3
client = boto3.client("bedrock-agentcore-control", region_name="us-west-2")
response = client.list_gateway_rules(
gatewayIdentifier="my-gateway-abc1234567"
)
for rule in response["gatewayRules"]:
print(f"Rule: {rule['ruleId']}, Priority: {rule['priority']}, Status: {rule['status']}")
```
## 刪除閘道規則
下列範例會刪除閘道規則。
**Example**
1. 執行以下命令：
```
aws bedrock-agentcore-control delete-gateway-rule \
--gateway-identifier my-gateway-abc1234567 \
--rule-id 12345678-1234-1234-1234-123456789012
```
1.
```
import boto3
client = boto3.client("bedrock-agentcore-control", region_name="us-west-2")
response = client.delete_gateway_rule(
gatewayIdentifier="my-gateway-abc1234567",
ruleId="12345678-1234-1234-1234-123456789012",
)
print(f"Status: {response['status']}")
```
