要获取AWS CloudFormation中ApiGateway资源的PathPart属性,可以使用AWS CloudFormation模板中的AWS::ApiGateway::RestApi和AWS::ApiGateway::Resource资源来定义API网关和资源,然后通过AWS::ApiGateway::Method资源来定义方法,并使用AWS::ApiGateway::Deployment资源部署API。
以下是一个示例CloudFormation模板,它定义了一个具有根路径和两个子路径的API网关:
{
"AWSTemplateFormatVersion": "2010-09-09",
"Resources": {
"MyApiGateway": {
"Type": "AWS::ApiGateway::RestApi",
"Properties": {
"Name": "MyApiGateway"
}
},
"RootResource": {
"Type": "AWS::ApiGateway::Resource",
"Properties": {
"RestApiId": {
"Ref": "MyApiGateway"
},
"ParentId": {
"Fn::GetAtt": ["MyApiGateway", "RootResourceId"]
},
"PathPart": "myapi"
}
},
"SubResource1": {
"Type": "AWS::ApiGateway::Resource",
"Properties": {
"RestApiId": {
"Ref": "MyApiGateway"
},
"ParentId": {
"Ref": "RootResource"
},
"PathPart": "resource1"
}
},
"SubResource2": {
"Type": "AWS::ApiGateway::Resource",
"Properties": {
"RestApiId": {
"Ref": "MyApiGateway"
},
"ParentId": {
"Ref": "RootResource"
},
"PathPart": "resource2"
}
},
"GetMethod": {
"Type": "AWS::ApiGateway::Method",
"Properties": {
"HttpMethod": "GET",
"ResourceId": {
"Ref": "RootResource"
},
"RestApiId": {
"Ref": "MyApiGateway"
},
"AuthorizationType": "NONE",
"Integration": {
"IntegrationHttpMethod": "GET",
"Type": "HTTP",
"Uri": "http://example.com"
}
}
},
"Deployment": {
"Type": "AWS::ApiGateway::Deployment",
"Properties": {
"RestApiId": {
"Ref": "MyApiGateway"
}
}
}
}
}
在这个示例中,我们定义了一个名为"MyApiGateway"的API网关,并创建了一个根路径为"/myapi"的资源。然后,我们创建了两个子路径为"/resource1"和"/resource2"的资源。最后,我们定义了一个GET方法,并将其关联到根路径资源。
要获取PathPart属性,可以使用CloudFormation输出(Output)。例如,可以通过以下方式输出根路径资源的PathPart属性:
"Outputs": {
"RootResourcePathPart": {
"Value": {
"Fn::GetAtt": ["RootResource", "PathPart"]
}
}
}
使用以上示例模板进行部署后,您可以查看CloudFormation堆栈的输出,以获取根路径资源的PathPart属性值。
