This topic describes how to call a cloud function using the invoke method.

Method definition

mpserverless.function.invoke(functionName: string, functionArgs?: object): Promise<Result>

Request parameters

Field	Type	Required	Description
`functionName`	String	Yes	The name of the cloud function to call.
`functionArgs`	Object	No	The input parameters for the cloud function. The function accepts these parameters through `ctx.args`.

Return parameters

Field name	Type	Description
`success`	Boolean	The execution status.
`requestId`	String	The request ID.
`result`	Any	The content returned by the API. The content is determined by the developer's code and the `content-type` in the request header. The default value is `application/json`.

Examples

Suppose you have a cloud function named sum. The function is defined as follows.

'use strict';

module.exports = async (ctx) => {
  const {a, b} = ctx.args;
  return a + b;
}

The following example shows how to call the sum cloud function from a Mini Program.

const { result } = await mpserverless.function.invoke(
    'sum', 
    { a: 1, b: 1 }
);
console.log('1 + 1 = ', result);  // 1 + 1 = 2

The following example shows how to call the sum cloud function from another cloud function.

'use strict';

module.exports = async (ctx) => {
    const { result } = await ctx.mpserverless.function.invoke(
        'sum', 
        { a: 1, b: 1 }
    );
    return result;
}
