HTTP

Overview​

The HTTP Element serves as the entry point for external access to the Babel application, supporting configurations such as path, method, headers, and body.

You can write code within the HTTP Element. The request parameters part of the HTTP Element is based on the Koa framework, so you can leverage a variety of APIs provided by Koa in your coding. For a more comprehensive understanding of Koa's APIs, you are encouraged to visit the Koa official website.

Features​

HTTP configuration​

The HTTP Element allows you to customize the request path and request method.

Path​

Move your mouse over the HTTP Element and click on the pencil icon to modify the path. Please note that the path generally needs to start with a '/'.

Access​

Access in the browser​

Once you have completed your coding, you can use a browser to access the HTTP Element.

Access in the Executor​

In development or debugging scenarios, using a browser to access the HTTP Element may not meet our needs, such as making POST requests or passing headers. For this reason, we provide the HTTP Executor.

The HTTP Executor is an online trigger for the HTTP Element. You can set query params, headers, and body parameters, then click the 'Run' button to trigger the HTTP Element.

In addition, the HTTP Executor also integrates the capabilities of the Observation View. After waiting for a short while, you can obtain detailed information about the code execution, including return values, line-by-line code values, and information about request parameters.
