FYI - Streaming Scriptrunner Rest Endpoint

[Daniel Garcia]

Wasn't sure if this would work but it does

import com.onresolve.scriptrunner.runner.rest.common.CustomEndpointDelegate
import groovy.transform.BaseScript
import javax.ws.rs.core.MultivaluedMap
import javax.ws.rs.core.Response
import javax.ws.rs.core.CacheControl
import javax.ws.rs.core.StreamingOutput
import java.io.OutputStream
import java.io.BufferedWriter
import java.io.OutputStreamWriter

@BaseScript CustomEndpointDelegate delegate

streaming_test(httpMethod: "GET") {MultivaluedMap queryParams, String body ->
    CacheControl cacheControl = new CacheControl()
    cacheControl.setNoCache(true)
    cacheControl.setMaxAge(-1)
    cacheControl.setMustRevalidate(true)

    return Response.ok().cacheControl(cacheControl).entity(new StreamingOutput() {
        public void write(OutputStream outputStream) {
            BufferedWriter writer = new BufferedWriter(new OutputStreamWriter(outputStream))
            for(int i = 0;i<10;i++) {
                writer.write("Test ${i}\n")
                writer.flush()
                sleep(1000)
            }
            writer.close()
        }

    }).build()
}
