c - gsoap ANSI C - 正确使用 gsoap 定义的 ANSI C 客户端调用 stub

Question

我刚开始使用 gsoap。我只使用 c++ 取得了 4 个小成功，但是我当前的项目限制了我设置源代码生成选项来创建纯 ANSI C(不是 c++)。我似乎无法成功调用该服务，错误返回为 0xC0000005 并给出以下代码片段，任何人都可以就我应该采取的不同做法提出建议:

片段包括
1. 客户端函数定义，
2. ns7结构定义，
3.简单调用应用:
谢谢，

这是客户端调用:

#include "soapH.h"  
#include "addressByAccount_ExtWS_BPELSOAP.nsmap"

SOAP_FMAC5 int SOAP_FMAC6 soap_call___ns1__accountsBPEL(struct soap *soap, const char *soap_endpoint, const char *soap_action, struct _ns7__accounts *ns7__accounts, struct     _ns9__accountsResponse *ns9__accountsResponse)  
{         
        struct __ns1__accountsBPEL soap_tmp___ns1__accountsBPEL;  
        if (!soap_endpoint)    
            soap_endpoint = "http://cctest3-v.physio-control.com:8080/ccx/addressByAccount-ExtWS-BPEL";    
        if (!soap_action)  
        soap_action = "http://www.physio-control.com/addressByAccount-ExtWS-BPEL/1.0/accounts";  
    soap->encodingStyle = NULL;  
    soap_tmp___ns1__accountsBPEL.ns7__accounts = ns7__accounts;  
    soap_begin(soap);  
    soap_serializeheader(soap);
    soap_serialize___ns1__accountsBPEL(soap, &soap_tmp___ns1__accountsBPEL);
    if (soap_begin_count(soap))
            return soap->error;
    if (soap->mode & SOAP_IO_LENGTH)
    {   if (soap_envelope_begin_out(soap)
         || soap_putheader(soap)
         || soap_body_begin_out(soap)
         || soap_put___ns1__accountsBPEL(soap, &soap_tmp___ns1__accountsBPEL, "-ns1:accountsBPEL", NULL)
         || soap_body_end_out(soap)
         || soap_envelope_end_out(soap))
             return soap->error;
    }
    if (soap_end_count(soap))
        return soap->error;
    if (soap_connect(soap, soap_endpoint, soap_action)
     || soap_envelope_begin_out(soap)
     || soap_putheader(soap)
     || soap_body_begin_out(soap)
     || soap_put___ns1__accountsBPEL(soap, &soap_tmp___ns1__accountsBPEL, "-ns1:accountsBPEL", NULL)
     || soap_body_end_out(soap)
     || soap_envelope_end_out(soap)
     || soap_end_send(soap))
        return soap_closesock(soap);
    if (!ns9__accountsResponse)
        return soap_closesock(soap);
    soap_default__ns9__accountsResponse(soap, ns9__accountsResponse);
    if (soap_begin_recv(soap)
     || soap_envelope_begin_in(soap)
     || soap_recv_header(soap)
     || soap_body_begin_in(soap))
        return soap_closesock(soap);
    soap_get__ns9__accountsResponse(soap, ns9__accountsResponse, "ns9:accountsResponse", "");
    if (soap->error)
        return soap_recv_fault(soap, 0);
    if (soap_body_end_in(soap)
     || soap_envelope_end_in(soap)
     || soap_end_recv(soap))
        return soap_closesock(soap);
    return soap_closesock(soap);
}

这是 ns7 结构:

struct _ns7__accounts
{
    int __sizeaccountNumber;    /* sequence of elements <accountNumber> */
    char **accountNumber;   /* required element of type xsd:string */
    char *requestIDTrackingForESB;  /* optional attribute of type xsd:string */
};

这是一个使用客户端调用的简单应用程序调用服务:

struct _ns7__accounts in, *pIn;
struct _ns9__accountsResponse out, *pOut;
int main(void)
{
    struct soap *soap = soap_new();

    //used to populate char ** in pIn
    char *pNumber=malloc(sizeof("00000201"));
    strcpy(pNumber, "00000201");

    pOut = &out;
    pIn = ∈

    pIn->__sizeaccountNumber = sizeof("00000201");
    pIn->accountNumber = &pNumber;
    pIn->requestIDTrackingForESB = malloc(sizeof(""));
    strcpy(pIn->requestIDTrackingForESB,"");

    if (soap_call___ns1__accountsBPEL(soap, "", "", pIn, pOut)== SOAP_OK)
    {
        printf("Soap OK...");
    }
    else  
    {
        printf(pIn->requestIDTrackingForESB);
        soap_print_fault(soap, stderr);
    }
    soap_end(soap);
    soap_free(soap);

   return 0;
} 

Answer 1

pIn->__sizeaccountNumber = sizeof("00000201");

__sizeaccountNumber 应设置为数组 (1) 的大小，而不是数组中第一个成员的大小。因为字符串以 null 结尾，所以不需要指定字符串的大小。

正如 pmg 已经评论过的，不要为 soap_endpoint 和 soap_action 传递 ""。您可以在函数中看到它为这些参数定义了默认值，但前提是您传递了 0(或 NULL)。

if (!soap_endpoint)    
  soap_endpoint = "http://cctest3-v.physio-control.com:8080/ccx/addressByAccount-ExtWS-BPEL";    
if (!soap_action)  
  soap_action = "http://www.physio-control.com/addressByAccount-ExtWS-BPEL/1.0/accounts";
