Question

我正在使用kSoap2访问soap Web服务。我在执行以下行

时收到 java.net.connectException

androidHttpTransport.call(Constants.SOAP_ACTION_GET_METHOD_NAME, envelope)

这种情况并非总是发生，但有些时候。这是连接超时到服务器的问题吗？如何在kSoap中增加连接时间？我用Google搜索，但无法找到解决方案。任何人都可以建议我解决这个错误的解决方案。

如何在kSoap中增加连接时间？

在某些情况下，HttpTransportSE忽略超时值似乎仍存在未解决的问题。请参阅此相关link。

但是，这方面的解决方案包括修改现有的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。

另请参阅ksoap never timeout。

希望它有所帮助。
