QuickGetBd Example

The QuickGetBd method is called to send a GET request to download a binary target, such as PDF, zip, image file, etc. into a Chilkat BinData object. Zig

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

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

    // This example assumes the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    const http = try chilkat.Http.init();
    defer http.deinit();
    http.setKeepResponseBody(true);

    const bd = try chilkat.BinData.init();
    defer bd.deinit();

    // Download the contents of a PDF file into the bd object.
    http.quickGetBd("https://www.chilkatsoft.com/hello.pdf", bd) catch {
        // This will happen if the response status code was 400 or greater,
        // or if the request could not be sent, or if no response was received.
        //
        // In other words, success will only be true if bd contains the desired content at the URL (not an error response).
        const status_code = http.getLastStatus();
        std.debug.print("Response status: {d}\n", .{status_code});

        if (status_code == 0) {
            // There was an error in communications.
            std.debug.print("{s}\n", .{try http.getLastErrorText(alloc)});
        } else {
            // We received a response status code indicating failure.
            // Examine the response body.
            std.debug.print("{s}\n", .{try http.getLastResponseBody(alloc)});
        }

        return;
    };

    // Load the downloaded PDF into a Chilkat PDF object.
    const pdf = try chilkat.Pdf.init();
    defer pdf.deinit();
    pdf.loadBd(bd) catch {
        std.debug.print("{s}\n", .{try pdf.getLastErrorText(alloc)});
        return;
    };

    // ...

    std.debug.print("Success.\n", .{});
