Merge SP-API JSON Order Arrays

See more Amazon SP-API Examples

Demonstrates how to merge JSON arrays for the case of Amazon SP-API orders. Rust

// Batch 1 File
let a1 = "{\"payload\": {\"Orders\": [{\"AmazonOrderId\": \"1\",\"OrderStatus\": \"Unshipped\"},{\"AmazonOrderId\": \"2\",\"OrderStatus\": \"Unshipped\"}]}".to_string();

// Batch 2 File
let a2 = "{\"payload\": {\"Orders\": [{\"AmazonOrderId\": \"3\",\"OrderStatus\": \"Unshipped\"},{\"AmazonOrderId\": \"4\",\"OrderStatus\": \"Unshipped\"}]}".to_string();

// Required Merged File
// {"payload": {"Orders": [{"AmazonOrderId": "1","OrderStatus": "Unshipped"},{"AmazonOrderId": "2","OrderStatus": "Unshipped"},{"AmazonOrderId": "3","OrderStatus": "Unshipped"},{"AmazonOrderId": "4","OrderStatus": "Unshipped"}]}

let _ = true;
let json1 = chilkat::JsonObject::new();
let _ = json1.load(&a1);

let json2 = chilkat::JsonObject::new();
let _ = json2.load(&a2);

// We're going to add the order records from json2 to json1.
let jarr1 = json1.array_of("payload.Orders").unwrap();
let jarr2 = json2.array_of("payload.Orders").unwrap();

let mut i = 0;
let num_orders = jarr2.size();
while i < num_orders {
    let j_order = jarr2.object_at(i).unwrap();
    // Assuming non-null return...
    let _ = jarr1.add_object_copy_at(-1, &j_order);
    i = i + 1;
}

// Show the merged JSON.
json1.set_emit_compact(false);
println!("{}", json1.emit().unwrap_or_default());

// Result:

// {
//   "payload": {
//     "Orders": [
//       {
//         "AmazonOrderId": "1",
//         "OrderStatus": "Unshipped"
//       },
//       {
//         "AmazonOrderId": "2",
//         "OrderStatus": "Unshipped"
//       },
//       {
//         "AmazonOrderId": "3",
//         "OrderStatus": "Unshipped"
//       },
//       {
//         "AmazonOrderId": "4",
//         "OrderStatus": "Unshipped"
//       }
//     ]
//   }
// }
