自定义资源缓存参考
本文将详细介绍实现缓存自定义资源的终结点的要求。 如果不熟悉 Azure 自定义资源提供程序,请参阅自定义资源提供程序概述。
定义缓存资源终结点
可以通过将 routingType
指定为“Proxy, Cache”来创建代理资源。
自定义资源提供程序示例:
{
"properties": {
"resourceTypes": [
{
"name": "myCustomResources",
"routingType": "Proxy, Cache",
"endpoint": "https://{endpointURL}/"
}
]
},
"location": "eastus",
"type": "Microsoft.CustomProviders/resourceProviders",
"id": "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.CustomProviders/resourceProviders/{resourceProviderName}",
"name": "{resourceProviderName}"
}
生成代理资源终结点
实现 "Proxy, Cache" 资源终结点的终结点必须处理 Azure 中新 API 的请求和响应。 在本例中,resourceType 将为 PUT
、GET
和 DELETE
生成一个新的 Azure 资源 API,以对单个资源执行 CRUD,并执行 GET
以检索所有现有资源。
注意
Azure API 会生成请求方法 PUT
、GET
和 DELETE
,但是缓存终结点只需处理 PUT
和 DELETE
。
我们建议终结点也实现 GET
。
创建自定义资源
Azure API 传入请求:
PUT https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.CustomProviders/resourceProviders/{resourceProviderName}/myCustomResources/{myCustomResourceName}?api-version=2018-09-01-preview
Authorization: Bearer eyJ0e...
Content-Type: application/json
{
"properties": {
"myProperty1": "myPropertyValue1",
"myProperty2": {
"myProperty3" : "myPropertyValue3"
}
}
}
然后,此请求将以以下形式转发到终结点:
PUT https://{endpointURL}/?api-version=2018-09-01-preview
Content-Type: application/json
X-MS-CustomProviders-RequestPath: /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.CustomProviders/resourceProviders/{resourceProviderName}/myCustomResources/{myCustomResourceName}
{
"properties": {
"myProperty1": "myPropertyValue1",
"myProperty2": {
"myProperty3" : "myPropertyValue3"
}
}
}
终结点的响应随后将转发回客户。 响应应返回:
- 有效的 JSON 对象文档。 所有数组和字符串都应嵌套在顶级对象下。
-
Content-Type
标头应设置为“application/json; charset=utf-8”。 - 自定义资源提供程序会覆盖请求的
name
、type
和id
字段。 - 自定义资源提供程序将仅返回缓存终结点的
properties
对象下的字段。
终结点响应:
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
{
"properties": {
"myProperty1": "myPropertyValue1",
"myProperty2": {
"myProperty3" : "myPropertyValue3"
}
}
}
自定义资源提供程序会自动为自定义资源生成 name
、id
和 type
字段。
Azure 自定义资源提供程序响应:
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
{
"name": "{myCustomResourceName}",
"id": "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.CustomProviders/resourceProviders/{resourceProviderName}/myCustomResources/{myCustomResourceName}",
"type": "Microsoft.CustomProviders/resourceProviders/myCustomResources",
"properties": {
"myProperty1": "myPropertyValue1",
"myProperty2": {
"myProperty3" : "myPropertyValue3"
}
}
}
删除自定义资源
Azure API 传入请求:
Delete https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.CustomProviders/resourceProviders/{resourceProviderName}/myCustomResources/{myCustomResourceName}?api-version=2018-09-01-preview
Authorization: Bearer eyJ0e...
Content-Type: application/json
然后,此请求将以以下形式转发到终结点:
Delete https://{endpointURL}/?api-version=2018-09-01-preview
Content-Type: application/json
X-MS-CustomProviders-RequestPath: /subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.CustomProviders/resourceProviders/{resourceProviderName}/myCustomResources/{myCustomResourceName}
终结点的响应随后将转发回客户。 响应应返回:
- 有效的 JSON 对象文档。 所有数组和字符串都应嵌套在顶级对象下。
-
Content-Type
标头应设置为“application/json; charset=utf-8”。 - 仅当返回 200 级别的响应时,Azure 自定义资源提供程序才会从其缓存中删除该项。 即使资源不存在,终结点也应返回 204。
终结点响应:
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
Azure 自定义资源提供程序响应:
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
检索自定义资源
Azure API 传入请求:
GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.CustomProviders/resourceProviders/{resourceProviderName}/myCustomResources/{myCustomResourceName}?api-version=2018-09-01-preview
Authorization: Bearer eyJ0e...
Content-Type: application/json
此请求不会转发到终结点。
Azure 自定义资源提供程序响应:
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
{
"name": "{myCustomResourceName}",
"id": "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.CustomProviders/resourceProviders/{resourceProviderName}/myCustomResources/{myCustomResourceName}",
"type": "Microsoft.CustomProviders/resourceProviders/myCustomResources",
"properties": {
"myProperty1": "myPropertyValue1",
"myProperty2": {
"myProperty3" : "myPropertyValue3"
}
}
}
枚举所有自定义资源
Azure API 传入请求:
GET https://management.azure.com/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.CustomProviders/resourceProviders/{resourceProviderName}/myCustomResources?api-version=2018-09-01-preview
Authorization: Bearer eyJ0e...
Content-Type: application/json
此请求不会转发到终结点。
Azure 自定义资源提供程序响应:
HTTP/1.1 200 OK
Content-Type: application/json; charset=utf-8
{
"value" : [
{
"name": "{myCustomResourceName}",
"id": "/subscriptions/{subscriptionId}/resourceGroups/{resourceGroupName}/providers/Microsoft.CustomProviders/resourceProviders/{resourceProviderName}/myCustomResources/{myCustomResourceName}",
"type": "Microsoft.CustomProviders/resourceProviders/myCustomResources",
"properties": {
"myProperty1": "myPropertyValue1",
"myProperty2": {
"myProperty3" : "myPropertyValue3"
}
}
}
]
}
