On the trigger list page of a function, click HTTP trigger and view the suffix of the value of Trigger URL. The suffix is the trigger identifier, which is in Function name-Version number format. As shown in the following figure, myhandlerxxxx-$latest is the HTTP trigger identifier, in which myhandlerxxxx is the function name, and $latest is the version number.

Calling a Function in an App

Import required modules.

import { cloudFunction } from '@kit.CloudFoundationKit';
import { BusinessError } from '@kit.BasicServicesKit';
import { hilog } from '@kit.PerformanceAnalysisKit';

Call call() to set a function and pass the function name to the method. The execution result will be returned.

(Optional) Set timeout to the timeout interval for calling the function, in milliseconds.
(Optional) Set version to the function version. The default value is $latest.
(Optional) If the function has input parameters, the data parameter can be converted into a JSON object or JSON character string.

Return the result asynchronously through a promise:

cloudFunction.call({
  name: 'sort', // Replace sort with the actual function name.
  version: '$latest', // If no version number is specified, the default value $latest is used.
  timeout: 10 * 1000, // Timeout interval, in milliseconds. The default value is 70 x 1000 milliseconds.
  data: {
    // data indicates the function request body.
    param1: 'val1',
    param2: 'val2'
  }
}).then((res: cloudFunction.FunctionResult) => {
  hilog.info(0x0000, 'function', `Succeeded in calling the function, result: ${JSON.stringify(res.result)}`);
}).catch((err: BusinessError) => {
  hilog.error(0x0000, 'function', `Failed to call function , code: ${err.code}, message: ${err.message}`);
});

Or return the result asynchronously through a callback:

cloudFunction.call({
  name: 'sort-id', // Replace sort-id with the actual function name.
  version: '$latest', // If no version number is specified, the default value $latest is used.
  timeout: 10 * 1000, // Timeout interval, in milliseconds. The default value is 70 x 1000 milliseconds.
  data: {
    // data indicates the function request body.
    param1: 'val1',
    param2: 'val2'
  }
}, (err: BusinessError, res: cloudFunction.FunctionResult) => {
  hilog.info(0x0000, 'function', `Succeeded in calling the function, result: ${JSON.stringify(res.result)}`);
  if (err) {
    hilog.error(0x0000, 'function', `Failed to call function , code: ${err.code}, message: ${err.message}`);
    return;
  }
});
