WASH_OUT解析故障:肥皂错误而不是HTML错误



所以,当您在轨道中使用wash_out宝石,而客户端发送不良XML时,响应就像:

<html>…
  <body>
    <h1>REXML::ParseException</h1> 
    …

而不是正确的肥皂响应,例如:

<soap:Body>
  <soap:Fault>
    <faultcode>soap:Client</faultcode>
    …

我首先尝试修补wash_out本身。我设法复制了rexml :: parseexception从其测试中进行这实际上是在wash_out之前解析(并爆炸)不好的XML触摸参数。

所以,wash_out宝石应该如何钩在铁轨上,以便可以拯救那些例外,仅适用于它拥有的路线?

这是我们必须使用的回溯。我很确定有一些指向它是完美的选择,但我还不知道哪个:

基本上,我们创建了一个机架中间件层,并在正确的位置插入了。
