WSO2 ESB是否支持使用JSON格式的REST到REST？

Question

我想使用WSO2 ESB作为网关.我正在使用版本4.0.3我有一些现有的RESTful服务与JSON消息.我知道ESB现在支持REST API.但我仍然找不到WSO2 ESB REST到REST的解决方案.我的意思是所有后端服务都是RESTful的JSON格式.谁能帮我？

Answer 1

是的,我们支持REST -REST服务,这意味着它在协议切换下进行分类,使用WSO2 ESB,它具有REST API,使您可以处理传入的REST或任何其他格式并进行调解并将它们传递到后端(它不会哪个协议是关键的)

如果您需要访问可能必须使用的表格数据,以下代理允许您将收到的REST消息传输到后端REST服务

<messageFormatter contentType ="application/x-www-form-urlencoded"class ="org.apache.axis2.transport.http.XFormURLEncodedFormatter"/>

<messageBuilder contentType ="application/x-www-form-urlencoded"class ="org.apache.synapse.commons.builders.XFormURLEncodedBuilder"/>

它允许您提取包含REST提交详细信息并根据您的喜好进行任何调解
