GSOAP:添加FAULT的处理

GSOAP:添加FAULT的处理

不知道是WSDL描述还是GSOAP自身的问题，有其生成的代码中在不支持Header的情况下，一样不支持对FAULT处理，于是，照着处理Header的过程，添加了对FAULT的处理。
     为处理FAULT，需要事先知道SOAP报文中将FAULT信息放在哪里，当然了，一般自定义扩充都放在DETAIL里面。只是开始不太确定，于是还特意发了个错误报文给对端，收到如下回复，从而确认猜测是对的，这样就可以修改了。

<? xml version='1.0' encoding='utf-8' ?> < soapenv:Envelope  xmlns:soapenv ="http://schemas.xmlsoap.org/soap/envelope/" >< soapenv:Header  />< soapenv:Body >< soapenv:Fault >< faultcode > soapenv:Client </ faultcode >< faultstring > Authentication Failed AccessCfgHelper.getProductInfor(productId) is empty or is null.. </ faultstring >< detail >< ns2:ServiceException  xmlns:ns2 ="http://www.chinatelecom.com.cn/schema/ctcc/common/v2_1" >< messageId > SVC0901 </ messageId >< text > CP/SP authenticate access failed:Authentication Failed AccessCfgHelper.getProductInfor(productId) is empty or is null.. </ text ></ ns2:ServiceException ></ detail ></ soapenv:Fault ></ soapenv:Body ></ soapenv:Envelope >

    首先在Detail结构里面添加所需要的Fault类型：

#ifndef SOAP_TYPE_SOAP_ENV__Detail
#define  SOAP_TYPE_SOAP_ENV__Detail (90)
/*  SOAP-ENV:Detail  */
struct  SOAP_ENV__Detail
{
public :
     // int __type;    /* any type of element <fault> (defined below) */
     // void *fault;    /* transient */
     // char *__any;

    sms2__ServiceException  * serviceException;
    sms2__PolicyException  * policyException;
};
#endif

    然后就是一样修改Detail的in和out函数了：

SOAP_FMAC3  int  SOAP_FMAC4 soap_out_SOAP_ENV__Detail( struct  soap  * soap,  const   char   * tag,  int  id,  const   struct  SOAP_ENV__Detail  * a,  const   char   * type)
{
     if  (soap_element_begin_out(soap, tag, soap_embedded_id(soap, id, a, SOAP_TYPE_SOAP_ENV__Detail), type))
         return  soap -> error;
     // if (soap_putelement(soap, a->fault, "fault", -1, a->__type))
     //     return soap->error;
     // soap_outliteral(soap, "-any", &a->__any, NULL);

     if (a  !=  NULL)
    {
         if (a -> serviceException  !=  NULL)
            a -> serviceException -> soap_out(soap,  " sms2:ServiceException " ,  - 1 ,  "" );
         else   if (a -> policyException  !=  NULL)
            a -> policyException -> soap_out(soap,  " sms2:PolicyException " ,  - 1 ,  "" );
    }

     return  soap_element_end_out(soap, tag);
}

SOAP_FMAC3  struct  SOAP_ENV__Detail  *  SOAP_FMAC4 soap_in_SOAP_ENV__Detail( struct  soap  * soap,  const   char   * tag,  struct  SOAP_ENV__Detail  * a,  const   char   * type)
{
     // size_t soap_flag_fault = 1;
     // size_t soap_flag___any = 1;
     if  (soap_element_begin_in(soap, tag,  0 , type))
         return  NULL;
    a  =  ( struct  SOAP_ENV__Detail  * )soap_id_enter(soap, soap -> id, a, SOAP_TYPE_SOAP_ENV__Detail,  sizeof ( struct  SOAP_ENV__Detail),  0 , NULL, NULL, NULL);
     if  ( ! a)
         return  NULL;
    soap_default_SOAP_ENV__Detail(soap, a);

     int  service  =   1 ;
     int  policy  =   1 ;

     if  (soap -> body  &&   !* soap -> href)
    {
         for  (;;)
        {    soap -> error  =  SOAP_TAG_MISMATCH;
             // if (soap_flag_fault && soap->error == SOAP_TAG_MISMATCH)
             //     if ((a->fault = soap_getelement(soap, &a->__type)))
             //     {    soap_flag_fault = 0;
             //         continue;
             //     }
             // if (soap_flag___any && (soap->error == SOAP_TAG_MISMATCH || soap->error == SOAP_NO_TAG))
             //     if (soap_inliteral(soap, "-any", &a->__any))
             //     {    soap_flag___any--;
             //         continue;
             //     }
            
             if  (soap -> error  ==  SOAP_TAG_MISMATCH)
            {
                 if (service  ==   1 )
                {
                    a -> serviceException  =  soap_in_sms2__ServiceException(soap,  " sms2:ServiceException " , a -> serviceException,  "" );
                     if (a -> serviceException)
                    {
                        service  =   0 ;
                         continue ;
                    }
                }
                 else   if (policy  ==   1 )
                {
                    a -> policyException  =  soap_in_sms2__PolicyException(soap,  " sms2:PolicyException " , a -> policyException,  "" );
                     if (a -> policyException)
                    {
                        policy  =   0 ;
                         continue ;
                    }
                }
                soap -> error  =  soap_ignore_element(soap);
            }
             if  (soap -> error  ==  SOAP_NO_TAG)
                 break ;
             if  (soap -> error)
                 return  NULL;
        }
         if  (soap_element_end_in(soap, tag))
             return  NULL;
    }
     else
    {    a  =  ( struct  SOAP_ENV__Detail  * )soap_id_forward(soap, soap -> href, ( void * )a,  0 , SOAP_TYPE_SOAP_ENV__Detail,  0 ,  sizeof ( struct  SOAP_ENV__Detail),  0 , NULL);
         if  (soap -> body  &&  soap_element_end_in(soap, tag))
             return  NULL;
    }
     return  a;
}

    由此，SOAP接口的主要问题除了“附件”还没有处理外，就都解决了，其他都是业务应用的问题了，处理起来就有底了～
