Zig Requires Chilkat v11.0.0+

Send JSON REST Request, Get JSON Response

See more REST Examples

Demonstrates sending a RESTful JSON request, and receiving a JSON response. This example will create a bucket in Google Cloud Storage (which involves sending and receiving JSON). Zig

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

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

    // This example will create a bucket in Google Cloud Storage.

    // It requires the Chilkat API to have been previously unlocked.
    // See Global Unlock Sample for sample code.

    const g_auth = try chilkat.AuthGoogle.init();
    defer g_auth.deinit();
    // Obtain an access token as shown in one of the following examples:
    // See Get Access Token using a Service Account JSON Key
    // See Get Access Token using a P12 File

    const rest = try chilkat.Rest.init();
    defer rest.deinit();

    // Connect using TLS.
    const b_auto_reconnect = true;
    try rest.connect("www.googleapis.com", 443, true, b_auto_reconnect);

    // Provide the authentication credentials (i.e. the access key)
    try rest.setAuthGoogle(g_auth);

    // Build the JSON request body for creating a bucket.
    // The only required property is the "name", but we'll add more
    // to make a better example..
    const json_req_body = try chilkat.JsonObject.init();
    defer json_req_body.deinit();
