使用BOTO3授予AWS Api网关权限以调用Lambda函数

我试图使用BOTO3创建一个调用lambda函数的Api Gateway方法 . 到目前为止，我一直无法找到如何授予必要的权限 .

奇怪的是，通过AWS控制台手动设置lambda方法名称会自动设置权限 . 我无法在代码中复制此内容 .

这是我用来设置网关的代码：

# Create a rest api
self.rest_api = self.apigateway.create_rest_api(
    name='AWS_CMS_Operations'
)

# Get the rest api's root id
root_id = self.apigateway.get_resources(
    restApiId=self.rest_api['id']
)['items'][0]['id']

# Create an api resource
api_resource = self.apigateway.create_resource(
    restApiId=self.rest_api['id'],
    parentId=root_id,
    pathPart='AWS_CMS_Manager'
)

# Add a post method to the rest api resource
api_method = self.apigateway.put_method(
    restApiId=self.rest_api['id'],
    resourceId=api_resource['id'],
    httpMethod='POST',
    authorizationType='NONE'
)

# Add an integration method to the api resource
self.apigateway.put_integration(
    restApiId=self.rest_api['id'],
    resourceId=api_resource['id'],
    httpMethod='POST',
    type='AWS',
    integrationHttpMethod='POST',
    uri=self.create_api_invocation_uri()
)

# Set the put method response for the api resource
self.apigateway.put_method_response(
    restApiId=self.rest_api['id'],
    resourceId=api_resource['id'],
    httpMethod='POST',
    statusCode='200',
    responseModels={
        'application/json': 'Empty'
    }
)

# Set the put integration response for the api resource
self.apigateway.put_integration_response(
    restApiId=self.rest_api['id'],
    resourceId=api_resource['id'],
    httpMethod='POST',
    statusCode='200',
    responseTemplates={
        'application/json': ''
    }
)

# Create a deployment of the rest api
self.apigateway.create_deployment(
    restApiId=self.rest_api['id'],
    stageName='prod'
)

# Give the api deployment permission to trigger the lambda function
self.lmda.add_permission(
    FunctionName=self.lmda_function['FunctionName'],
    StatementId='apigateway-production-aws-cms',
    Action='lambda:InvokeFunction',
    Principal='apigateway.amazonaws.com',
    SourceArn=self.create_api_permission_uri(api_resource)
)

除了为网关设置适当的权限以调用lambda之外，一切正常 .
