Groovy中HttpURLConnection的连接超时 [英] Connection timeout with HttpURLConnection in Groovy

问题描述

任何人都可以向我展示我的错误吗？

  def url = new URL（https://www.google.com）
 HttpURLConnection连接=（HttpURLConnection）url.openConnection（）
 connection.setRequestMethod（GET）
 // connection.setConnectTimeout（10000）
 connection.connect（）
 if（connection.responseCode == 200 || connection.responseCode = = 201）{
 def returnMessage = connection.content 
 
 //打印完整回复
 println returnMessage 
} else {
 println错误连接到+ url 
} 
  

错误2012-07-05 00：04：05,950 [http-bio-8080-exec-6] ERROR errors.GrailsExceptionResolver - 处理请求时发生ConnectException：[GET] / CopperApplications / urlTracker连接超时：连接。 Stacktrace如下：消息：连接超时：connec

解决方案

您的代码看起来正确，并在Groovy上产生预期的1.7.9与1.6.0_33 JVM。您的网络可能存在某些问题（如连接超时错误所示）。

I am always getting the "Error Connecting to ${url}" message?

Can anyone please show me my mistake?

        def url = new URL("https://www.google.com")
        HttpURLConnection connection = (HttpURLConnection) url.openConnection()
        connection.setRequestMethod("GET")
        // connection.setConnectTimeout(10000)
        connection.connect()
        if (connection.responseCode == 200 || connection.responseCode == 201) {
            def returnMessage = connection.content

            //print out the full response
            println returnMessage
        } else {
            println "Error Connecting to " + url
        }

| Error 2012-07-05 00:04:05,950 [http-bio-8080-exec-6] ERROR errors.GrailsExceptionResolver - ConnectException occurred when processing request: [GET] /CopperApplications/urlTracker Connection timed out: connect. Stacktrace follows: Message: Connection timed out: connec

解决方案

Your code seems correct, and produces the expected(?) results on Groovy 1.7.9 with 1.6.0_33 JVM. There is likely something amiss with your network (as indicated by the connection timeout error).
