Question

我有一个基于HTTP方法的代理服务将请求发送到由WSO2 Application Server托管的应用程序或WSO2数据服务服务器上的数据服务。

某些PUT操作不需要请求体，因为它们只是根据URI语义更改了某些内容，但是当我没有有效负载时，我无法使其工作。

服务看起来像这样：

<?xml version="1.0" encoding="UTF-8"?>

                    </send>
                </case>
                <default>
                    <property name="called.url" expression="fn:concat(get-property('uri.var.as.service.url'), $axis2:REST_URL_POSTFIX)"/>

                    </send>
                </default>
            </switch>
        </inSequence>
        <outSequence>
            <log level="custom" separator="\n">

            </log>
            <send />
        </outSequence>
    </target>
</proxy>

即使使用FORCE_POST_PUT_NOBODY，我们也会收到org.apache.axis2.AxisFault: No JSON payload provided。在完整的堆栈跟踪下方：

WSO2 ESB版本：4.9.0
爪哇：
- java版“1.7.0_79”
- Java（TM）SE运行时环境（版本1.7.0_79-b15）
- Java HotSpot（TM）64位服务器VM（内置24.79-b02，混合模式）

像{}之类的机构工作正常，但我寻找一个“透明”的解决方案，没有这样的解决方法。有没有人有这样的问题？

更新：这适用于WSO2 ESB 5.0.0：https://wso2.org/jira/browse/ESBJAVA-4270。有没有人“轻松”升级到5.0.0？或者更好的是，有没有人知道这个补丁，没有其他变化？
