Question

我有这个代码，你能帮我解决这个问题吗？我写了这段代码：

out = new DataOutputStream(urlConnection.getOutputStream());//exception occur

String content = (String) remoteUrlList.get(urlID + ".params");
content = (content == null ? "" : content + "&") + "content=" +   URLEncoder.encode(textArea.getText());
if (debug > 0) System.err.println("Capture: " + content);
out.writeBytes(content);
out.flush();
out.close();

// retrieve response from the remote host and display it.
if (debug > 0) System.err.println("Capture: reading response");
in = new BufferedReader(new InputStreamReader(urlConnection.getInputStream()));
String str;
while (null != ((str = in.readLine()))) {
  System.out.println("Capture: " + str);
}
in.close();

doneDialog.pack();
doneDialog.setVisible(true);

错误列表是：

我在我的本地网络上尝试这个，所以没有防火墙问题。
有人可以帮忙吗？

Answer 1

我有一些东西网，如何添加代理，当我尝试这个我没有得到项目中的设置，配置所以..所以请让我知道如何做到这一点..请参阅下面的如何做到这一点。

在项目设置，选项卡配置，编辑当前默认配置文件，选项卡服务器，将代理设置添加到'额外JVM参数'中进行配置，例如添加：

-Dhttp.proxyHost = myproxyserver.com -Dhttp.proxyPort = 80

Answer 2

您要连接的地址应该存在。例如如果要在端口8080上打开与localhost的连接，那么应该有一个服务器正在侦听该端口。

Answer 3

可能是防火墙问题？检查您是否可以使用telnet url 80

通过telnet访问该URL

java.net.ConnectException：连接超时：发生连接异常
