Response parameters


Name	Type	Example	Description
ETag	String	e19d5cd5af0378da05f63f891c74****	The value that is used to ensure that the modified function is consistent with the function that is expected to be modified.
codeChecksum	String	2825179536350****	The CRC-64 value of the function code package.
codeSize	Long	421	The size of the function code package. Unit: byte.
createdTime	String	2020-04-01T08:15:27Z	The time when the function was created.
description	String	test_description	The description of the function.
environmentVariables	Map		The environment variables that you configured for the function. You can obtain the values of the environment variables from the function. For more information, see Overview.
functionId	String	aa715851-1c20-4b89-a8fb-***	The ID that is generated by the system for the function. Each function ID is unique in Function Compute.
functionName	String	function_name	The name of the function.
handler	String	index.handler	The handler of the function. For more information, see Function handler.
lastModifiedTime	Long	2020-04-01T08:15:27Z	The time when the function was last updated.
memorySize	Integer	256	The memory size for the function. Unit: MB. The memory size is a multiple of 64 MB. The memory size that is available for an instance varies based on the instance type. For more information, see Instance specifications.
runtime	String	python3	The runtime environment of the function. The following runtime environments are supported: Node.js 6.x, Node.js 8.x, Node.js 10.x, Node.js 12.x, Node.js 14.x, Python 2.7, Python 3, Java 8, Java 11, PHP 7.2, .NET Core 2.1, Go 1.x, custom runtimes, and custom container runtimes. For more information about the runtime environments that are supported by Function Compute, see Supported function runtime environments.
timeout	Integer	60	The timeout period for the execution of the function. Unit: seconds. Default value: 60. Valid values: 1 to 86400. When this period ends, the execution of the function is terminated.
initializationTimeout	Integer	60	The timeout period for the execution of the initializer function. Unit: seconds. Default value: 3. Valid values: 1 to 300. When this period ends, the execution of the initializer function is terminated.
initializer	String	index.handler	The handler of the initializer function. The format of the value varies based on the programming language that you use. For more information, see Initializer function.
caPort	Integer	9000	The port on which the HTTP server listens for the custom runtime or custom container runtime.
customContainerConfig	CustomContainerConfigInfo		The configurations of the custom container runtime. After you configure the custom container runtime, you can use custom container images to execute functions.
