java - 运行 axis2 客户端版本 1.5

Question

所以我已经没有办法尝试让客户端连接到我通过 axis2 运行的 SOAP 服务了。

我尝试了两种方法，一种是使用 wsdl2java 构建 stub 和关联的客户端类，然后编写一个客户端类来构建请求消息并通过 stub 发送它们。另一种方法是使用 ServiceClient 连接..

两者都以自己的方式失败..

选项 #1，每次通过 stub 发送消息时，我都会返回:

org.apache.axis2.AxisFault: The input stream for an incoming message is null.
at org.apache.axis2.transport.TransportUtils.createSOAPMessage(TransportUtils.java:87)
at org.apache.axis2.transport.TransportUtils.createSOAPMessage(TransportUtils.java:67)

at org.apache.axis2.description.OutInAxisOperationClient.executeImpl(OutInAxisOperation.java:229)
at org.apache.axis2.client.OperationClient.execute(OperationClient.java:165)

选项#2，每次我运行它都会得到这个异常:

org.apache.axis2.deployment.DeploymentException: org.apache.axis2.transport.local.LocalTransportSender

            OMElement vctest = loyaltyClient.verifyCustomer("6177740603");
            Options options = new Options();
            options.setTo(targetEPR);

options.setTransportInProtocol(Constants.TRANSPORT_HTTP);

            ServiceClient sender = new ServiceClient();
            sender.setOptions(options);
            OMElement result = sender.sendReceive(vctest);

            String response = result.getFirstElement().getText();
            System.out.println(response);

        } catch (Exception e) { //(XMLStreamException e) {
            System.out.println(e.toString());
        }
    }

Answer 1

在使用 Axis 连接到 .Net 服务提供商时，我也遇到了错误“传入消息的输入流为空”。

问题是 .Net 不支持称为“分块编码”的功能，默认情况下，Axis 会将其请求 header 分成 block ，这被认为是符合 HTTP 1.1 的。

无论如何，您可以通过执行以下操作在 Axis 中关闭此功能:

// Turn off the Axsis Chunked feature, some service providers (like .Net) don't support chunked headers.
Options options = serviceClient.getOptions();
options.setProperty(HTTPConstants.CHUNKED, Constants.VALUE_FALSE);
serviceClient.setOptions(options);            

这对我有用。处理 .Net 服务时要确保的另一件事是能够指定端口名称并确保您的消息负载具有每个元素的 namespace 前缀。

希望此信息对某人有所帮助。
