X-Backside-Transport Header有什么作用？ [英] What does X-Backside-Transport Header do?

问题描述

我第一次遇到这个标题并且不确定它的作用或含义。我一直在搜索，找不到我要找的东西。

I have come across this header for the first time and not sure what it does or mean. I have searched around and couldn't find what I was looking for.

我正在尝试使用PHP SoapClient类来使用SOAP API，并且它返回一个空的响应，这些响应标头。此外，没有抛出异常。

I am trying to consume a SOAP API using PHP SoapClient class and it's returning an empty response and these response headers. Also, no exception is thrown.

HTTP/1.1 200 OK
X-Backside-Transport: FAIL FAIL,FAIL FAIL
Connection: close
Transfer-Encoding: chunked
Content-Type: text/xml
Date: Tue, 21 Jun 2016 20:09:50 GMT
X-Client-IP: xx.xxx.xxx.xxx

感谢任何帮助。

推荐答案

您尝试通信的Web服务似乎落后于xml防火墙（可能是IBM DataPower，它确实发送X - failere上的-Backside-Transport标头）并阻止错误响应（ aka。fault message ）。这是xml防火墙的默认行为。根本原因可能是格式错误的soap消息（，即：错误的数据类型）或服务器站点异常。

It seems that the web service you're trying to communicate is behind the xml firewall (probably IBM DataPower, it does send X-Backside-Transport header on failere) and blocks the error response (aka. fault message). This is the default behaviour for the xml firewalls. Root cause can be malformed soap message (i.e.: wrong data type) or an server site exception.

为了解决问题，您应该与网络服务所有者联系。

In order to solve the problem, you should contact with the web service owner.
