Question

因此，当您在Rails中使用wash_out gem并且客户端发送错误的XML时，响应如下：

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

而不是正确的SOAP响应，如下所示：

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

我首先尝试修补wash_out本身。我设法重现了 REXML :: ParseException来自其测试，但后来发现令我沮丧 Rails实际上在wash_out之前解析（并爆炸）坏XML 触及参数。

那么，如何将wash_out gem挂钩到Rails中以便它可以拯救它们例外，仅适用于它拥有的路线？

这是我们必须处理的回溯。我很确定有一些指出它是完美的，但我还不知道哪个：

基本上，我们创建了一个Rack Middleware图层并将其插入到正确的位置。
