Environment

tcb.SYMBOL_CURRENT_ENV

Field description: This field is used during initialization to specify the environment for requesting the current cloud function.

Note: Starting from v3, if the env parameter is not specified during initialization init({}), the current cloud function environment ID will be used by default instead of the default CloudBase environment. To use the default CloudBase environment, specify init({env: tcb.SYMBOL_DEFAULT_ENV}).

Sample code

import tcb from '@cloudbase/node-sdk'

// Initialize using the current cloud function environment
const app = tcb.init({ env: tcb.SYMBOL_CURRENT_ENV })

exports.main = async (event, context) => {
  //Business logic.
}

parseContext

1. Interface Description

Function: Parse environment variables in the cloud function environment. (Parameters can be obtained directly from the cloud function's entry parameter context.)

Interface declaration: parseContext(context): Object

2. Response

Field	Type	Required	Description
memory_limit_in_mb	Number	Yes	Cloud function memory limit
time_limit_in_ms	Number	Yes	Execution time limit
request_id	String	Required	Request ID
environ	Object	Yes	Environment variable object (containing user-defined custom environment variable values)
function_version	String	Yes	Cloud function version
function_name	String	Yes	Cloud function name
namespace	String	Yes	Namespace

3. Sample Code

import tcb from '@cloudbase/node-sdk'

exports.main = async (event, context) => {
    // The context parameter is taken from the context object of the cloud function's entry function handler
    const envObj = tcb.parseContext(context)
    // Print cloud function environment variables
    console.log(envObj)
