func_vpc	func_vpc	Virtual Private Cloud (VPC) configuration. See Table 6.

Table 3 func_code parameters
Parameter	Type	Description
file	String	Function code (deprecated).
link	String	Function code link (code can be downloaded through the OBS SDK).

Table 4 strategy_config parameter
Parameter	Type	Description
concurrency	Int	0: The function is disabled. -1: The function is enabled.

Example

Example request
