java - 客户计算机上的 Apache httpclient 超时(处理请求时捕获 I/O 异常 : Connection timed out

Question

我在尝试使用 Apache HttpClient 3.0 通过 Java 代码连接和查询 Rally 时遇到超时问题

我使用 xmlhttprequest 确实没有遇到这个问题。

除了出现故障的机器之外，我无法在任何机器上重现此问题。由于主机是 https，这可能是 cacerts 问题吗？有没有办法检查代理？有任何记录建议可以获取更多信息吗？

谢谢!

错误信息是:org.apache.commons.httpclient.HttpmethodDirectorexecuteWithRetry信息:处理请求时捕获 I/O 异常(java.net.ConnectException):连接超时:连接。

他们正在运行 java jdk 1.6。

protected String doGet(HttpClient httpClient, GetMethod getMethod)
throws IOException
 {
httpClient.getState().setCredentials(new AuthScope(this.host, this.port, null), new UsernamePasswordCredentials(this.username, this.password));
httpClient.getParams().setParameter("http.socket.timeout", new Integer(1000000));
getMethod.setDoAuthentication(true);
getMethod.getParams().setParameter("http.socket.timeout", new Integer(1000000));
getMethod.addRequestHeader("X-RallyIntegrationName", this.integrationName);
getMethod.addRequestHeader("X-RallyIntegrationVendor", this.integrationVendor);
getMethod.addRequestHeader("X-RallyIntegrationVersion", this.integrationVersion);
//getMethod.addRequestHeader("X-RallyIntegrationOS", getOSInfo());
//getMethod.addRequestHeader("X-RallyIntegrationPlatform", getProductInfo());
getMethod.addRequestHeader("X-RallyIntegrationLibrary", "Apache Commons HTTP Client 3.0");
try
{ 
  double timeBefore = System.currentTimeMillis() / 1000;
  int result = httpClient.executeMethod(getMethod);
  double timeAfter = System.currentTimeMillis() / 1000;
  System.out.println("Seconds to query for Workspace: " + (timeAfter - timeBefore));
  if (result != 200) {
    throw new IOException("Http GET Failed" + getMethod.getStatusLine());
  }
  String response = getMethod.getResponseBodyAsString();
  System.out.println(response);
  return response;
}
finally
{
  getMethod.releaseConnection();
}

}}

您可以使用适用于 Java 的 Rally REST 工具包吗:https://github.com/RallyTools/RallyRestToolkitForJava

这可以处理您上面编写的大量代码(并且是使用较新版本的 Apache Http 组件 - 4.2.x 构建的)
