gsoap服务端的开发及注意事项

1. 可以先用JAVA生成接口的WSDL文件；

2. 自己编写一个接口文件，然后使用" soapcpp2 -i soapsample.h" 生成C的服务端和客户端，其中服务端文件为soapsamleService.h. soapsamleService.cpp， 客户端为soapsampleProxy.h, soapsampleProxy.cpp文件；

3. 编写服务端的监听程序， 实现接口函数；

需要注意的几点：

1 如果客户端为JAVA程序，则附件的格式应该为 BIMARY；

2 接口函数应该始终返回0，否则客户端无法收到服务端返回的消息；

3 使用soap_set_mode( soap, SOAP_C_UTFSTRING)来设置编码方式。

具体开发说明请参看Gsoap的官方网站http://www.cs.fsu.edu/~engelen/soapdoc2.html#tth_sEc7.2.4

以下为gsoap的一个例子：

#include "soapH.h"
#include < pthread.h >
#define BACKLOG (100) // Max. request backlog
int main(int argc, char **argv)
{
struct soap soap;
soap_init(&soap);
if (argc < 2) // no args: assume this is a CGI application
{
soap_serve(&soap); // serve request, one thread, CGI style
soap_destroy(&soap); // dealloc C++ data
soap_end(&soap); // dealloc data and clean up
}
else
{
soap.send_timeout = 60; // 60 seconds
soap.recv_timeout = 60; // 60 seconds
soap.accept_timeout = 3600; // server stops after 1 hour of inactivity
soap.max_keep_alive = 100; // max keep-alive sequence
void *process_request(void*);
struct soap *tsoap;
pthread_t tid;
int port = atoi(argv[1]); // first command-line arg is port
SOAP_SOCKET m, s;
m = soap_bind(&soap, NULL, port, BACKLOG);
if (!soap_valid_socket(m))
exit(1);
fprintf(stderr, "Socket connection successful %d/n", m);
for (;;)
{
s = soap_accept(&soap);
if (!soap_valid_socket(s))
{
if (soap.errnum)
{
soap_print_fault(&soap, stderr);
exit(1);
}
fprintf(stderr, "server timed out/n");
break;
}
fprintf(stderr, "Thread %d accepts socket %d connection from IP %d.%d.%d.%d/n", i, s, (soap.ip >> 24)&0xFF, (soap.ip >> 16)&0xFF, (soap.ip >> 8)&0xFF, soap.ip&0xFF);
tsoap = soap_copy(&soap); // make a safe copy
if (!tsoap)
break;
pthread_create(&tid, NULL, (void*(*)(void*))process_request, (void*)tsoap);
}
}
soap_done(&soap); // detach soap struct
return 0;
}
void *process_request(void *soap)
{
pthread_detach(pthread_self());
soap_serve((struct soap*)soap);
soap_destroy((struct soap*)soap); // dealloc C++ data
soap_end((struct soap*)soap); // dealloc data and clean up
soap_done((struct soap*)soap); // detach soap struct
free(soap);
return NULL;
}
