API Manager 2.1.0启用Binary Relay后POST响应被binary元素包裹问题咨询

问题场景 #

启用Binary Relay功能时，通过简单直通中介发送POST请求。

异常表现 #

此时ESB生成的响应负载会被包裹在<binary>元素中，完整HTTP响应示例如下：

HTTP/1.1 200 OK
Access-Control-Allow-Origin: *
Access-Control-Allow-Methods: POST
Access-Control-Allow-Headers: authorization,Access-Control-Allow-Origin,Content-Type,SOAPAction
Content-Type: text/xml; charset=UTF-8
Date: Tue, 16 Jan 2018 14:53:00 GMT
Transfer-Encoding: chunked
Connection: close
<?xml version='1.0' encoding='UTF-8'?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"><soapenv:Body><ns:binary xmlns:ns="http://ws.apache.org/commons/ns/payload">DCAAAAApACkAAAJxdXVpZDo3MTRDNkM0MC00NT.......</ns:binary></soapenv:Body></soapenv:Envelope>

版本对比 #

这个异常仅出现在API Manager 2.1.0中，在ESB 5.0.0和API Manager 2.0.0版本中，该功能运行正常，响应负载不会被<binary>元素包裹。
