handler	Handler of the function in the format of "xx.xx". It must contain a period (.). For example, for Node.js function myfunction.handler, the file name is myfunction.js, and the entry point function is handler.
memory_size	Memory (MB) consumed by the function. The value can be 128, 256, 512, 768, 1,024, 1,280, 1,536, 1,792, 2,048, 2,560, 3,072, 3,584, 4,096, 8,192, or 10,240.
cpu	CPU usage of a function.
code_type	Function code type. Options: inline: inline code zip: ZIP file jar: JAR file (mainly for Java functions) obs: function code stored in an Object Storage Service (OBS) bucket
code_url	When code_type is set to obs, this parameter indicates the address of a function code package in OBS. When code_type is set to inline, zip, or jar, this parameter is left blank.
code_filename	Function file name. When code_type is set to zip or jar, this parameter is required. When code_type is set to obs or inline, this parameter is not required.
code_size	Code size in bytes.
user_data	Name/Value information defined for the function. For example, if a function needs to access a host, define Host={host_ip}. You can define a maximum of 20 such parameters, and their total length cannot exceed 4 KB.
digest	SHA512 hash value of function code, which is used to determine whether the function is changed.
version	Function version, which is automatically generated by the system. The version name is in the format of "vYYYYMMDD-HHMMSS" (v+year/month/day-hour/minute/second).
image_name	Internal identifier of a function version.
xrole	Agency used by the function. You need to create an agency on the Identity and Access Management (IAM) console. This field is mandatory when a function needs to access other services.
app_xrole	Agency used by the function app. You need to create an agency on the IAM console. This field is mandatory when a function needs to access other services.
description	Description of the function.
version_description	Description of the function version.
last_modified	Time when the function was last updated.
func_code	Function code. See Table 2.
depend_list	Dependency list.
strategy_config	Function policy configuration. See Table 3.
extend_config	Function extension configuration.
dependencies	Dependency list. See Table 5.
initializer_handler	Initializer of the function in the format of "xx.xx". It must contain a period (.). For example, for Node.js function myfunction.initializer, the file name is myfunction.js, and the initialization function is initializer.
initializer_timeout	Maximum duration the function can be initialized. Value range: 1s–300s.
func_vpc	Virtual Private Cloud (VPC) configuration. See Table 4.
mount_config	File system configuration. See Table 6.

size	Int	No	Size of the dependency package.
name	String	No	Name of the dependency package.

Function URN Format

urn:fss:<region_id>:<project_id>:function:<package>:<function_name>[:<version>|:!<alias>]

Note

A function URN is divided into eight fields by colons. The value of region_id is included in the system configuration. You can set this parameter to the same as that in the backend. The content in the brackets ([]) is a function version or alias. If you enter an alias, add an exclamation mark (!) in front of it for easy identification.

When a function URN is used as an API parameter, you can provide it in a simplified format as follows:

1 field: <function_name>. project_id is obtained from a token, package is default, and version is latest.
2 fields: <package>:<function_name>. project_id is obtained from a token, and version is latest.
3 fields: <project_id>:<package>:<function_name>. version is latest.
4 fields: <project_id>:<package>:<function_name>:<Version or Alias>.
7 fields: urn:fss:<region_id>:<project_id>:function:<package>:<function_name>. version is latest.
8 fields: urn:fss:<region_id>:<project_id>:function:<package>:<function_name>:<Version or Alias>.
