如果您从 WCF 服务收到响应 500（内部错误），请尝试在 WCF 服务的 web.config 中设置 includeexceptiondetailinfaults=true 。（http://msdn.microsoft.com/cs-cz/library/system.servicemodel.description.servicedebugbehavior.includeexceptiondetailinfaults(v=vs.110).aspx）
然后你会得到详细的异常（错误的肥皂动作，错误的格式......）
从 PL/SQL 调用 WCF 服务。
utl_http 但它有效。
