Get the JWS Payload into BinData

See more JSON Web Signatures (JWS) Examples

Demonstrates Jws.GetPayloadBd, which writes the payload of a loaded JWS as raw bytes into a BinData.

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    const jws = try chilkat.Jws.init();
    defer jws.deinit();

    // Load the JWS compact serialization.
    const jws_compact = "eyJhbGciOiJIUzI1NiJ9.VGhpcyBpcyB0aGUgY29udGVudCB0byBzaWduLg.<signature>";
    jws.loadJws(jws_compact) catch {
        std.debug.print("{s}\n", .{try jws.getLastErrorText(alloc)});
        return;
    };

    // Get the JWS payload as raw bytes into a BinData.
    const bd_payload = try chilkat.BinData.init();
    defer bd_payload.deinit();
    jws.getPayloadBd(bd_payload) catch {
        std.debug.print("{s}\n", .{try jws.getLastErrorText(alloc)});
        return;

    std.debug.print("Payload is {d} bytes.\n", .{bd_payload.getNumBytes()});
