ITIDA Create Canonical JSON

See more Egypt ITIDA Examples

Demonstrates creating the canonical (ITIDA) version of a JSON document. The document in the example is the one at https://sdk.invoicing.eta.gov.eg/files/one-doc.json

Note: This example requires Chilkat v9.5.0.92 or greater.

Objective-C

#import <CkoStringBuilder.h>
#import <NSString.h>

BOOL success = NO;

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

// Note: This example requires Chilkat v9.5.0.92 or greater.
// (In v9.5.0.92, the "itida" encoding was added to StringBuilder's Encode method.)
CkoStringBuilder *sb = [[CkoStringBuilder alloc] init];

// This is the file at https://sdk.invoicing.eta.gov.eg/files/one-doc.json
success = [sb LoadFile: @"qa_data/itida/sdk.invoicing.eta.gov.eg/files/one-doc.json" charset: @"utf-8"];
if (success == NO) {
    NSLog(@"%@",@"Failed to load input file.");
    return;
}

// Convert the contents of sb to the ITIDA canonical form.
// Always pass utf-8 for the 2nd arg.
[sb Encode: @"itida" charset: @"utf-8"];

NSString *canonical = [sb GetAsString];

NSLog(@"%@",canonical);

// Output: 
// "SomeValue""DELIVERY""APPROACH""SomeValue""PACKAGING""SomeValue""DATEVALIDITY""2020-09-28T09:30:10Z"........."TOTALAMOUNT""5191.50""EXTRADISCOUNTAMOUNT""5.00""TOTALITEMSDISCOUNTAMOUNT""14.00"

// Let's verify we got the correct result.
