想返回一个字符串。求源代码。要源代码。
教程看了一堆了。
在服务器网址上看不到GetPointData函数。只有那个add函数。时间紧张,来不及研究,所以求帮助。
本人的.h文件
//gsoap ns service name: Service_MYJK //gsoap ns service namespace: http://localhost/Service_MYJK.wsdl //gsoap ns service location: http://localhost //gsoap ns service executable: Service_MYJK.cgi //gsoap ns service encoding: encoded //gsoap ns schema namespace: urn:Service_MYJK int ns__add(int num1, int num2, int* sum); int GetPointData(int nMessage, int nArea, char* pcUser,char** pcRes); int SetPointData(int nWtgID, char* pcUser);
service的cpp文件
#include <stdio.h>
#include <stdlib.h>
#include “stdsoap2.h”
#include “soapH.h”
#include “Service_MYJK.nsmap”
#include “MainControlApi.h”

int http_get(struct soap *soap);

}
}
return 0;
}
//server端的实现函数与add.h中声明的函数相同,但是多了一个当前的soap连接的参数
int ns__add(struct soap *add_soap, int num1, int num2, int *sum)
{

return 0;
}
int GetPointData(struct soap *add_soap, int nMessage, int nArea, char* pcUser, char** pcRes)

//http_get是一个函数

//gsoap ns service name: testDemo //gsoap ns service namespace: http://localhost/testDemo.wsdl //gsoap ns service location: http://localhost //gsoap ns service executable: testDemo.cgi //gsoap ns service encoding: encoded //gsoap ns schema namespace: urn:add typedef std::string xsd__string; int ns__add( int num1, int num2, int* sum ); int ns__getStr( xsd__string src, xsd__string *result);
然后生成对应的文件
service端

client端

你的服务器.h文件把函数改成这样
int ns__GetPointData(int nMessage, int nArea, char* pcUser,char** pcRes);
int ns__SetPointData(int nWtgID, char* pcUser,char** pcRes);
char*是参数,char**放最后是返回值。
假如要返回多个,用个struct*
然后改你的服务器cpp文件
int ns__GetPointData(struct soap *add_soap, int nMessage, int nArea, char* pcUser, char** pcRes)
{
sprintf_s(pcUser, nArea,”test result 1″);
sprintf_s(*pcRes, nArea, “test result 2”);
GetPointData(pcUser, nMessage, nArea);
//不知道你这个GetPointData是什么
//用sprintf_s(*ret, strlen(res), “返回值”,);修改返回值,假如编码统一就能返回中文。
return 0;
}
int ns__SetPointData(struct soap *add_soap, int nWtgID, char* pcUser,char** pcRes)
{
sprintf_s(pcUser, nWtgID, “SetPointData test result 2”);
return 0;
}
把.h重新和exe放一起,用命令行编译。
