Groovy cometd 客户端 LongPollingTransport.create() 抛出 MissingMethodException

Question

我的groovy代码：

import org.cometd.client.BayeuxClient;
import org.cometd.client.transport.ClientTransport;
import org.cometd.client.transport.LongPollingTransport;
import org.eclipse.jetty.client.HttpClient as MyHttpClient    

def myurl = "http://192.168.11.170:8080/"

MyHttpClient httpClient = new MyHttpClient()

httpClient.start()

println (httpClient.GET(myurl).getStatus())

BayeuxClient client = new BayeuxClient(myurl, LongPollingTransport.create(null))
client.handshake()
client.waitFor(1000, BayeuxClient.State.CONNECTED)

这里我想做一个handshake。它只是此处显示的文档示例代码 https://docs.cometd.org/current/apidocs/org/cometd/client/BayeuxClient.html。但我收到如下所示的错误。不知道我做错了什么？

输出：

200
groovy.lang.MissingMethodException: No signature of method: static org.cometd.client.transport.LongPollingTransport.create() is applicable for argument types: (null) values: [null]
Possible solutions: grep(), terminate(), iterator(), accept(java.lang.String), accept(java.lang.String), print(java.lang.Object)

Answer 1

BayeuxClient 的 Javadoc 与 LongPollingTransport class 完全不同步 - there is no such method as LongPollingTransport.create(arg).

相反，您可以尝试使用此 class 的常规构造函数，例如

BayeuxClient client = new BayeuxClient(myurl, new LongPollingTransport([:], httpClient))

Reference: https://docs.cometd.org/current/apidocs/org/cometd/client/transport/LongPollingTransport.html#LongPollingTransport-java.util.Map-org.eclipse.jetty.client.HttpClient-

第一个参数是选项映射（在此示例中为空），第二个参数是 Jetty 的实例 HttpClient 您导入为 MyHttpClient。
