HTTP/2

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.

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, Apicat 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 Apicat's default configuration to ensure compatibility.

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

Complete configuration options:

HTTP/2 ALPN: Default option, Apicat 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/1.1: Default option, establish a connection using the HTTP/1.1 protocol and send requests using the HTTP/1.1 protocol.
