示例1: serialize
String JSCryptoKeySerializationJWK::serialize(ExecState* exec, const CryptoKey& key)
{
std::unique_ptr<CryptoKeyData> keyData = key.exportData();
if (!keyData) {
// This generally shouldn't happen as long as all key types implement exportData(), but as underlying libraries return errors, there may be some rare failure conditions.
throwTypeError(exec, "Couldn't export key material");
return String();
}
JSObject* result = constructEmptyObject(exec);
addJWKAlgorithmToJSON(exec, result, key);
if (exec->hadException())
return String();
addBoolToJSON(exec, result, "extractable", key.extractable());
addJWKUseToJSON(exec, result, key.usagesBitmap());
if (exec->hadException())
return String();
if (isCryptoKeyDataOctetSequence(*keyData))
buildJSONForOctetSequence(exec, toCryptoKeyDataOctetSequence(*keyData).octetSequence(), result);
else if (isCryptoKeyDataRSAComponents(*keyData))
