Arrays with any number of elements can be passed using JSON. The new HTTP server code makes it easier.
// class "HTTP server Functions test.cs"
using System.Text.Json.Nodes;
static partial class Functions {
//client example: LaHttp.CallJ("TestJsonArray", new string[] { "a", "b" });
//client example without LaHttp: internet.http.Post("http://localhost:4455/TestJsonArray", internet.jsonContent(new string[] { "a", "b" }));
public static void TestJsonArray(string[] a) {
foreach (string v in a) {
print.it(v);
}
}
}
