How to use

Add jar in buid.gradle

compile project (':quickconnect')

Add QuickConnectInterceptor when creating OkHttpClient

val client = 
    OkHttpClient.Builder()
        .addInterceptor(QuickConnectInterceptor())
        .build()

Send a request to Synology NAS server. To use QuickConnect, you need to have a QuickConnect ID. To compose a HTTP request, replace hostname with QuickConnect ID. For example, if your QuickConnect ID is "dsm" and want to send a pingpong request(webman/pingpong.cgi?action=cors), the request should be looked like:

val quickConnectId = "dsm"
val request = 
    Request.Builder()
        .url(HttpUrl.parse("http://$quickConnectId/webman/pingpong.cgi?action=cors"))
        .build();
client.newCall(request).execute();
