HTTP/2

In this section, you will learn how to request HTTP/2 APIs with Apidog.

HTTP/2 is the latest version of the Hypertext Transfer Protocol (HTTP). It is a major update to the HTTP/1.1 protocol that offers better performance, security, and features.

info

The latest version of Apidog now supports requesting HTTP/2 APIs. Please click the gear icon in the top-right corner of the software and check for updates in "About".

Turn On Compatibility Switch​

You can request HTTP/2 APIs directly within an HTTP project, but you need to ensure that the HTTP/2 compatibility switch is enabled in "Settings" → "Feature Settings" → "Advanced Settings."

After enabling the compatibility switch, when requesting HTTP/2 APIs, Apidog will automatically upgrade the request protocol to HTTP/2.

HTTP/2 sample API: https://http2.pro/api/v1

More Settings​

You can manually switch relevant settings in "Settings" → "Advanced Settings." It is recommended to use Apidog's default configuration to ensure compatibility.

After enabling the compatibility switch, Apidog will automatically upgrade the request protocol to HTTP/2 while requesting HTTP/2 APIs.

Complete configuration options:

  • HTTPS

    HTTP/2 ALPN: Default option, Apidog will attempt to establish a connection using the HTTP/2 protocol and send requests using the HTTP/2 protocol. If the API does not support it, it will automatically fall back to HTTP/1.1.

    HTTP/1.1: Use the original HTTP connection method and do not use the HTTP/2 protocol.

  • HTTP

    HTTP/1.1: Default option, establish a connection using the HTTP/1.1 protocol and send requests using the HTTP/1.1 protocol.

    HTTP/2 Prior Knowledge: Establish a h2c connection. If the API does not support the HTTP/2 protocol, the connection will fail directly without automatically back to HTTP/1.1.
