Step 4: Test the demo

After the above steps are finished, you can interact with the interfaces of the WeChat mini program and call cloud functions to test the WeChat Mini Program SDK.

  • Open the demo project and test the user interfaces.

  • Run the test based on the following JavaScript program:

    import { request } from '../../utils/request';
    const params = {
        data: {
        // action: the interface name. For more information, see the API reference documentation.
            action: "hello",
        // params: the parameters.
            params: {
                hello: 'world'
    // Use request encapsulated in the demo to make the API request.
    // Use the Promise object or async and await keywords to make the API request.
    request(params).then(res =>{
        console.log('res', res);
    }).catch(err => console.log('err', err))

If the response is returned without any error, the SDK configuration is successful. Then, you can proceed with more API requests. For more information, see API List.
