用于 Python 的 Azure App Configuration SDK

具有功能标志和动态设置的集中式配置管理。

安装

pip install azure-appconfiguration

环境变量

AZURE_APPCONFIGURATION_CONNECTION_STRING=Endpoint=https://<name>.azconfig.io;Id=...;Secret=...
# Or for Entra ID:
AZURE_APPCONFIGURATION_ENDPOINT=https://<name>.azconfig.io

认证

连接字符串

from azure.appconfiguration import AzureAppConfigurationClient

client = AzureAppConfigurationClient.from_connection_string(
    os.environ["AZURE_APPCONFIGURATION_CONNECTION_STRING"]
)

Entra ID

from azure.appconfiguration import AzureAppConfigurationClient
from azure.identity import DefaultAzureCredential

client = AzureAppConfigurationClient(
    base_url=os.environ["AZURE_APPCONFIGURATION_ENDPOINT"],
    credential=DefaultAzureCredential()
)

配置设置

获取设置

setting = client.get_configuration_setting(key="app:settings:message")
print(f"{setting.key} = {setting.value}")

带标签获取

# Labels allow environment-specific values
setting = client.get_configuration_setting(
    key="app:settings:message",
    label="production"
)

设置配置

from azure.appconfiguration import ConfigurationSetting

setting = ConfigurationSetting(
    key="app:settings:message",
    value="Hello, World!",
    label="development",
    content_type="text/plain",
    tags={"environment": "dev"}
)

client.set_configuration_setting(setting)

删除设置

client.delete_configuration_setting(
    key="app:settings:message",
    label="development"
)

列出设置

所有设置

settings = client.list_configuration_settings()
for setting in settings:
    print(f"{setting.key} [{setting.label}] = {setting.value}")

按键前缀过滤

settings = client.list_configuration_settings(
    key_filter="app:settings:*"
)

按标签过滤

settings = client.list_configuration_settings(
    label_filter="production"
)

功能标志

设置功能标志

from azure.appconfiguration import ConfigurationSetting
import json

feature_flag = ConfigurationSetting(
    key=".appconfig.featureflag/beta-feature",
    value=json.dumps({
        "id": "beta-feature",
        "enabled": True,
        "conditions": {
            "client_filters": []
        }
    }),
    content_type="application/vnd.microsoft.appconfig.ff+json;charset=utf-8"
)

client.set_configuration_setting(feature_flag)

获取功能标志

setting = client.get_configuration_setting(
    key=".appconfig.featureflag/beta-feature"
)
flag_data = json.loads(setting.value)
print(f"Feature enabled: {flag_data['enabled']}")

列出功能标志

flags = client.list_configuration_settings(
    key_filter=".appconfig.featureflag/*"
)
for flag in flags:
    data = json.loads(flag.value)
    print(f"{data['id']}: {'enabled' if data['enabled'] else 'disabled'}")

只读设置

# Make setting read-only
client.set_read_only(
    configuration_setting=setting,
    read_only=True
)

# Remove read-only
client.set_read_only(
    configuration_setting=setting,
    read_only=False
)

快照

创建快照

from azure.appconfiguration import ConfigurationSnapshot, ConfigurationSettingFilter

snapshot = ConfigurationSnapshot(
    name="v1-snapshot",
    filters=[
        ConfigurationSettingFilter(key="app:*", label="production")
    ]
)

created = client.begin_create_snapshot(
    name="v1-snapshot",
    snapshot=snapshot
).result()

列出快照设置

settings = client.list_configuration_settings(
    snapshot_name="v1-snapshot"
)

异步客户端

from azure.appconfiguration.aio import AzureAppConfigurationClient
from azure.identity.aio import DefaultAzureCredential

async def main():
    credential = DefaultAzureCredential()
    client = AzureAppConfigurationClient(
        base_url=endpoint,
        credential=credential
    )
    
    setting = await client.get_configuration_setting(key="app:message")
    print(setting.value)
    
    await client.close()
    await credential.close()

客户端操作

| 操作 | 描述 | |-----------|-------------| | get_configuration_setting | 获取单个设置 | | set_configuration_setting | 创建或更新设置 | | delete_configuration_setting | 删除设置 | | list_configuration_settings | 带过滤器列出 | | set_read_only | 锁定/解锁设置 | | begin_create_snapshot | 创建时间点快照 | | list_snapshots | 列出所有快照 |

最佳实践

1. 使用标签区分环境（开发、预发布、生产）
2. 使用键前缀组织设置（如 app:database:*）
3. 使用快照进行版本化配置发布
4. 使用只读保护关键设置不被意外修改
5. 使用异步客户端处理高并发场景
6. 使用 Entra ID而非连接字符串以获得更好的安全性
