Question

我使用gsoap与以下网络服务进行通信： http://ws.cdyne.com/delayedstockquote/delayedstockquote.asmx?wsdl

我运行soapcpp2来生成头文件，这里是我的soapClient.c： http://pastebin.com/Bjev3dP7

的getQuote：

struct _ns1__GetQuote
{
/// Element "StockSymbol" of XSD type xs:string.
    char*                                StockSymbol                    0;      ///< Optional element.
/// Element "LicenseKey" of XSD type xs:string.
    char*                                LicenseKey                     0;      ///< Optional element.
};

struct _ns1__GetQuoteResponse
{
/// Element "GetQuoteResult" of XSD type "http://ws.cdyne.com/":QuoteData.
    struct ns1__QuoteData*               GetQuoteResult                 1;      ///< Required element.
};

到目前为止，这是我的代码：

#include "soapH.h"
#include "DelayedStockQuoteSoap.nsmap"
#include "soapClient.c"

struct _ns1__GetQuote *ns1__GetQuote;
struct _ns1__GetQuoteResponse *response;

main() {
  struct soap *soap ;
  ns1__GetQuote->StockSymbol = "goog";
  ns1__GetQuote->LicenseKey = "0";
  if (soap_call___ns1__GetQuote(soap, NULL, NULL, ns1__GetQuote, &response) == SOAP_OK)
    printf("yay\n");
}

我在运行此代码时会收到一个段错误，是否有任何提示？

在您的代码中有许多错误，没有分配任何内容。

首先，你需要使用：

分配struct soap

struct soap *soap = soap_new();

需要分配GetQuote方法的下一个输入和输出参数，这可以很容易地在堆栈中存储：

struct _ns1__GetQuote ns1__GetQuote;
struct _ns1__GetQuoteResponse response;

将所有内容放在一起可能会产生类似的结果：

#include "soapH.h"
#include "DelayedStockQuoteSoap.nsmap"
#include "soapClient.c"

main() {
  struct soap *soap = soap_new();
  struct _ns1__GetQuote ns1__GetQuote;
  struct _ns1__GetQuoteResponse response;
  ns1__GetQuote.StockSymbol = "goog";
  ns1__GetQuote.LicenseKey = "0";
  if (soap_call___ns1__GetQuote(soap, NULL, NULL, &ns1__GetQuote, &response) == SOAP_OK)
    printf("yay\n");
}
