android - ksoap2 问题 java.net.ConnectException

Question

我正在使用 kSoap2 访问 soap 网络服务。我在执行以下行时收到 java.net.connectException

androidHttpTransport.call(Constants.SOAP_ACTION_GET_METHOD_NAME, envelope)   

这种情况并不总是发生，但有时会发生。这是服务器连接超时的问题吗？如何增加 kSoap 中的连接超时？我用谷歌搜索，但找不到解决方案。谁能建议我解决此错误的解决方案。

How to increase the connection time out in kSoap ?

HttpTransportSE 在某些情况下忽略超时值似乎仍然存在 Unresolved 问题。看到这个相关link .

但是，对此的解决方案涉及修改现有的 ksoap2 API。

感谢 Lightsoftai 的开发人员您现在可以使用以下代码将超时添加到 HttpTransportSE:

注意:您可以为此使用 ksoap2 API 版本 2.5.2 或更高版本

       /**
       * Creates instance of HttpTransportSE with set url
       *
       * @param url 
       *             the destination to POST SOAP data
       */
         public HttpTransportSE(String url) {
         super(url);
         }

       /**
      * Creates instance of HttpTransportSE with set url
      *
      * @param url
      *            the destination to POST SOAP data
      * @param timeout
      *               timeout for connection and Read Timeouts (milliseconds)
       */
       public HttpTransportSE(String url, int timeout) {
       super(url, timeout);
          }

您可以从 here 下载相同的 jar 文件.

希望对您有所帮助。
