服务端使用webservice框架axis1.4开发,客户端发送的报文中,HTTP head 没有SOAPAction
返回报文:
<?xml version="1.0" encoding="UTF-8"?><soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" 
xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
 <soapenv:Body>
  <soapenv:Fault>
   <faultcode xmlns:ns1="http://xml.apache.org/axis/">ns1:Client.NoSOAPAction</faultcode>
   <faultstring>no SOAPAction header!</faultstring>
   <detail>
    <ns2:hostname xmlns:ns2="http://xml.apache.org/axis/">host1</ns2:hostname>
   </detail>
  </soapenv:Fault>
 </soapenv:Body>
</soapenv:Envelope> 




原因:
? ? ?这是axis1.4的一个bug,正常代码应该是在校验客户端访问的HTTP头部信息时,获取SOAPAction,如果为空,则直接取request.getContextPath();看axis源码org.apache.axis.transport.http.AxisServlet类中的getSoapAction(HttpServletRequest req);这个方法确实是想这么写来着,但是写法上有问题,才会出现这个bug。
? ?下面是axisServlet中的getSoapAction代码:
?
/**
     * Extract the SOAPAction header.
     * if SOAPAction is null then we'll we be forced to scan the body for it.
     * if SOAPAction is "" then use the URL
     * @param req incoming request
     * @return the action
     * @throws AxisFault
     */
    private String getSoapAction(HttpServletRequest req) throws AxisFault {
        String soapAction = req.getHeader(HTTPConstants.HEADER_SOAP_ACTION );
        if (soapAction == null) {
            String contentType = req.getHeader(HTTPConstants.HEADER_CONTENT_TYPE );
            if(contentType != null) {
                int index = contentType.indexOf( "action" );
                if(index != -1){
                    soapAction = contentType.substring(index + 7);
                }
            }
        }
        if ( isDebug) {
            log.debug( "HEADER_SOAP_ACTION:" + soapAction);
            /**
             * Technically,if we don't find this header,we should probably fault.
             * It's required in the SOAP HTTP binding.
             */
        }
        if (soapAction == null) {
            AxisFault af = new AxisFault( "Client.NoSOAPAction",Messages. getMessage( "noHeader00","SOAPAction" ),null,null);
            exceptionLog .error(Messages.getMessage( "genFault00" ),af);
            throw af;
        }
        // the SOAP 1.1 spec & WS-I 1.0 says:
        // soapaction    = "SOAPAction" ":" [ <"> URI-reference <"> ]
        // some implementations leave off the quotes
        // we strip them if they are present
        if (soapAction.startsWith( """ ) && soapAction.endsWith(""" )
            && soapAction.length() >= 2) {
            int end = soapAction.length() - 1;
            soapAction = soapAction.substring(1,end);
        }
        if (soapAction.length() == 0) {
            soapAction = req.getContextPath(); // Is this right?
        }
        return soapAction;
    }



上面代码一目了然,就是说在尝试取 req.getHeader(" SOAPAction " )和 req.getHeader(" Content-Type " )中的action都为空时,就直接记录到 AxisFault ?类中,返回给客户端。然后下面的 ?? if ?(soapAction.length() == 0) { ? soapAction = req.getContextPath();? // Is this right? ?}
不会执行到


解决方法:
? ? ?根据上面所述,有两个方法:
? ? ?1.要求客户端访问时,在HTTP header中必须有SOAPAction(soapaction的内容是什么我感觉不重要,即便为空字符串我测试也是可以正常的。)
? ? ?2.就是修改服务端axis bug,首先想到的就是自定义一个servlet然后继承AxisServlet,改写getSoapAction 代码,但是会发现getSoapAction是private的,所以只能copy整个AxisServlet代码修改getSoapAction部分(只需把写AxisFault部分代码放在最后面,注意上面中的if语句中,soapAction.length()==0 要改一下,因为如果soapAction为空这样会抛出空指针异常的。),然后修改web.xml中配置的servlet为自定义的类路径。
