msgArgData

Get the raw Candid-encoded arguments of the current call.

import { msgArgData, IDL, update, candidDecode } from 'azle';

export default class {
    @update([], IDL.Text)
    inspectArgs(): string {
        const rawArgs = msgArgData();

        // Decode assuming the call was made with [string, number] args
        const decoded = candidDecode([IDL.Text, IDL.Nat], rawArgs);

        return `Raw args length: ${rawArgs.length}, Decoded: ${JSON.stringify(decoded)}`;
    }
}

The msgArgData function returns the raw bytes of the arguments passed to the current method call. This is typically used in advanced scenarios where you need to handle method arguments manually.

Use Cases:

• Custom argument validation
• Method argument introspection
• Debugging and logging raw call data
• Building generic proxy or forwarding mechanisms

Important Notes:

• Returns raw Candid-encoded bytes
• Useful for methods with { manual: true } option
• Must be decoded using candidDecode to get typed values
