(JavaScript) How to Load a JWK Set Published at a Remote URL
Demonstrates how to load a JWK set published at a remote URL. In general, this example can fetch any JSON, or any text (non-binary) document from a remote URL. It uses the Chilkat HTTP API to do it. Note: This example requires Chilkat v11.0.0 or greater.
var success = false;
// This example assumes the Chilkat HTTP API to have been previously unlocked.
// See Global Unlock Sample for sample code.
var http = new CkHttp();
// I put a sample JWK set at this URL: https://www.chilkatsoft.com/data/jwk-set.json
// You can test this example with it.
var sbJwkSet = new CkStringBuilder();
success = http.QuickGetSb("https://www.chilkatsoft.com/data/jwk-set.json",sbJwkSet);
if (success == false) {
console.log(http.LastErrorText);
return;
}
// Load the JWK into a JSON object..
var jwkSet = new CkJsonObject();
jwkSet.LoadSb(sbJwkSet);
jwkSet.EmitCompact = false;
console.log("The full JWK Key Set:");
console.log(jwkSet.Emit());
// Iterate over each key...
var jwk = new CkJsonObject();
var numKeys = jwkSet.SizeOfArray("keys");
var i = 0;
while (i < numKeys) {
jwkSet.I = i;
console.log("---- JWK " + i + " ----");
jwkSet.ObjectOf2("keys[i]",jwk);
jwk.EmitCompact = false;
console.log(jwk.Emit());
i = i+1;
}
// Output:
// The full JWK Key Set:
