我一直在尝试WSO2 API管理器3.2.0来为SOAP web服务生成RESTAPI，并成功地完成了这些过程。我启用了消息连线跟踪，以便在日志中查看请求响应。我可以看到，正在创建一个格式正确的消息并将其发送到后端服务，但是，响应并不像预期的那样。我注意到一些额外的文本(通常是">16e"，如倒数第二行所示(在XML有效负载之前发送，因此作为有效负载进行处理。我怀疑这是我问题的原因，但我无法追踪它的来源。

当我使用XML请求并直接调用后端SOAP服务时，我得到了成功的响应。你知道这篇文章的责任是什么吗？我需要做些什么来摆脱它？我们将感谢您的帮助。

分块
数据以一系列块的形式发送。在这种情况下，Content-Length标头被省略每个块的开头，您需要以十六进制格式添加当前块的长度，然后是"\r\n"，然后是块本身，然后是另一个"\r\n"。终止区块是规则块，但长度为零的情况除外。紧随其后的是拖车，拖车由实体头字段的(可能为空(序列。
问题出在内容类型上。我正在发送值"；application/soap+xml"；并将其改为"；text/xml"；通过在xml配置文件中为<CARBON_HOME>存储库/部署/服务器/突触配置/默认/api/
<property name="ContentType" value="text/xml" scope="axis2" type="STRING"/>
这就是让它发挥作用所需要的一切。
