Request syntax

GET /services/{serviceName.qualifier}/functions HTTP/1.1

Request parameters

Parameter	Type	Position	Required	Example	Description
serviceName	String	Path	No	service_name	The name of the service.
qualifier	String	Path	No	test	The version or alias of the service.
limit	Integer	Query	No	20	The maximum number of resources to be returned. Default value: 20. The value cannot exceed 100. The number of returned resources is smaller than or equal to the specified number.
nextToken	String	Query	No	next_service	The token used to obtain more results. If the number of resources exceeds the limit, the nextToken parameter is returned. Include this parameter in subsequent invocations to obtain more results. You do not need to provide this parameter in the first invocation.
prefix	String	Query	No	prefix_text	The prefix that the names of returned resources must contain.
startKey	String	Query	No	next_service	The starting position of the result list. Results are sorted in the alphabetical order and those results following startKey (inclusive) are listed.

Response parameters

Parameter	Type	Example	Description
functions	Array		An array that consists of the information of functions.
codeChecksum	String	282517953635042****	The CRC-64 value of the function code package.
codeSize	Long	421	The size of the function code package. Unit: byte.
createdTime	String	2020-04-01T08:14:58Z	The time when the function was created.
customContainerConfig	CustomContainerConfig		The configuration of the custom container. After you configure the custom container runtime, you can use custom container images to execute functions.
description	String	test_description	The description of the function.
environmentVariables	Map		The environment variables configured for the function. The values of the environment variables are obtained from the function. For more information, see Overview.
functionId	String	e68905d5-f81c***	The ID generated by the system for each function. It must be globally unique.
functionName	String	function_name	The name of the function.
handler	String	index.handler	The handler of the function. The format is determined by the programming language. For more information, see Function handlers.
lastModifiedTime	Long	2020-04-01T08:14:58Z	The last time when the function was updated.
memorySize	Integer	256	The memory size of the function. Unit: MB. The memory size is a multiple of 64 MB. Instance types have different memory specifications. For more information, see Instance types.
runtime	String	python3	The runtime environment of the function. 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 expires, 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 expires, the execution of the initializer function is terminated.
initializer	String	index.handler	The handler of the initializer function. The format is determined by the programming language. 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.
nextToken	String	next_service	The token used to obtain more results. If this value is not returned, all results are returned.
