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.

Rust

// 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.)
let sb = chilkat::StringBuilder::new();

// This is the file at https://sdk.invoicing.eta.gov.eg/files/one-doc.json
if sb.load_file("qa_data/itida/sdk.invoicing.eta.gov.eg/files/one-doc.json", "utf-8").is_err() {
    println!("Failed to load input file.");
    return;
}

// Convert the contents of sb to the ITIDA canonical form.
// Always pass utf-8 for the 2nd arg.
let _ = sb.encode("itida", "utf-8");

let canonical = sb.get_as_string().unwrap_or_default();

println!("{}", 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.
let sb_expected = chilkat::StringBuilder::new();
if sb_expected.load_file("qa_data/itida/sdk.invoicing.eta.gov.eg/files/one-doc-serialized.json.txt", "utf-8").is_err() {
    println!("Failed to expected output file.");
    return;
}

// Compare our computed canonical string with the expected result.
if sb.contents_equal_sb(&sb_expected, true) {
    println!("The computed canonical result is correct.");
} else {
    println!("The computed canonical result is NOT correct.");
}
