Zig Requires Chilkat v11.0.0+

HTTP POST JSON and Parse JSON Response

See more HTTP Examples

Demonstrates how to send a JSON POST and then parse the JSON response. Zig

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

    const alloc = init.arena.allocator();

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

    // The JSON response to be parsed looks like this:
    // {
    //   "LifeAmount": 513.85,
    //   "LifeResidualAmount": 123.38,
    //   "CriticalIllnessAmount": 0,

    //   "PolicyFeeSecondary": 0,
    //   "PolicyFeeHidden": 50.00,
    //   "PolicyFeeHiddenSecondary": 0
    // }

    // We can get the floating point numbers as strings.  Then convert to double
    // using the appropriate string-to-double conversion for your programming language.
    // For example, in C++ use atof.  In C# use Convert.ToDouble.
