Question

wso2esb-4.0.3

我可以执行其他样本。我确实在运行ESB和StockService。看起来JSON转换正在发生，但jsonclient无法处理JSON响应。

ant jsonclient -Daddurl=http://localhost:9000/services/SimpleStockQuoteService -Dtrpurl=http://localhost:8280/services/JSONProxy

我不是Axis2客户专家。任何人都有办法让这个例子有效吗？

从示例中发送带有JSON有效负载的curl也会产生错误：

curl -X POST -H 'Content-type: application/json' -d '{"getQuote":{"request":{"symbol":"IBM"}}}' http://localhost:8280/services/JSONProxy

Answer 1

当您将消息从json转换为soap11时，请确保将端点格式设置为soap11。您可以通过在synapse配置中设置端点地址来实现：<address uri="http://localhost:9000/services/SimpleStockQuoteService" format="soap11"/>。

Answer 2

我在Tomcat上部署了CXF-JAX-WS Web服务。我得到的问题是当JSON Post请求转换为XML for SOAP时，它不会获得命名空间（只是一个普通的xml）。我尝试设置format =“soap11”但没有成功。但是，当从Webservice获取某些数据时，从XML转换 - ＆gt; JSON非常完美。我参考了WSO2 ESB的样本440。任何帮助将不胜感激。
