c++ - gSOAP C++ 多线程独立服务器和客户端示例

Question

我是 gSOAP 的新手，有人可以发布一个工作 gSOAP 多线程 C++ 独立服务器和客户端。在 gSOAP 文档中，多线程独立服务器没有详细说明在何处调用 web 服务函数，例如 int ns_add(int a , int b) ，也没有调用 main 中头文件 calc.h 中定义的函数服务器类 - calc.cpp。

请给出一步一步的指导，这将有助于像我这样的新人。

您的回复将不胜感激。

这是 c++ 中 gsoap 的一个示例：在头文件中，我们有例如这个函数（服务）：

int yb__add_list(char *name, char *tel, char **result);
int yb__del_list(int no, char **result); 
int yb__get_tel_by_name(char *name, char **result);
int yb__get_name_by_tel(char *tel, char **result);
int yb__get_list(char **result);

通过运行 soapcpp2 interface.h 生成我们的存根后，我们有一些文件，检查文档以了解它：soapStub.h、soapH.h、soapC.c、soapClient.c、soapServer.c 然后我们可以实现这样的服务：

int main(int argc, char **argv)
{ int m, s; /* master and slave sockets */
struct soap soap;

soap_init(&soap);
load_list();
show_list();
if (argc < 2)
soap_serve(&soap);  /* serve as CGI application */
else
{ m = soap_bind(&soap, NULL, atoi(argv[1]), 100);
if (m < 0)
{ soap_print_fault(&soap, stderr);
  exit(-1);
}
fprintf(stderr, "Socket connection successful: master socket = %d\n", m);
for ( ; ; )
{ s = soap_accept(&soap);
  fprintf(stderr, "Socket connection successful: slave socket = %d\n", s);
  if (s < 0)
  { soap_print_fault(&soap, stderr);
    exit(1);
  } 
  soap_serve(&soap);
  soap_end(&soap);
  }
  }
  return 0;
  } 

 int yb__add_list(struct soap *soap, char *name, char *tel, char **result)
 {
 printf("the name is %s, tel is %s\n", name, tel);
 *result = (char *) soap_malloc(soap, 50);
 if(add_list(name, tel) > 0)
 strcpy(*result, "Success!");
 else
 strcpy(*result, "Failed!");
 show_list();
 save_list();
 return SOAP_OK;
 }
 int yb__del_list(struct soap *soap, int no, char **result)
 {
 *result = (char *) soap_malloc(soap, 50);
 if(delete_list(no) > 0)
 strcpy(*result, "Success!");
 else
 strcpy(*result, "Failed!");
 save_list();
 return SOAP_OK;
 }
 int yb__get_tel_by_name(struct soap *soap, char *name, char **result)
 {
 char tel[50];
 *result = (char *) soap_malloc(soap, 200);
 if(get_tel_by_name(name, tel ) == 1)
 sprintf(*result, "The tel of %s is: \n%s\nSuccess!", name, tel);
 else
 strcpy(*result, "Failed!");
 return SOAP_OK;
 }
 int yb__get_name_by_tel(struct soap *soap, char *tel, char **result)
 {
 char name[50];

 *result = (char *) soap_malloc(soap, 200);
 if(get_name_by_tel(tel, name) == 1)
 sprintf(*result, "The owner of %s is: \n%s\nSuccess!", tel, name);
 else
 strcpy(*result, "Failed!");
 return SOAP_OK;
 }
 int yb__get_list(struct soap *soap, char **result)
 {
 *result = (char *)malloc(1024);
 get_list(*result);
 return SOAP_OK;  
 }

您可以在终端 ./server +Port 中将您的服务作为单独的服务器执行，然后在客户端：

const char server[] = "localhost:8080/";
int executecmd(char *inbuf,  struct soap *p_soap);
int main(void)
{
struct soap soap;
char inbuf[MAX_CANON];
int ret;
soap_init(&soap);
for( ; ; ) {
fputs(NEWLINE_STRING, stdout);
fputs(CLIENT_PROMPT_STRING, stdout);
if (fgets(inbuf, MAX_CANON, stdin) == NULL)
  break;
if (*(inbuf + strlen(inbuf) - 1) == NEWLINE_SYMBOL)
  *(inbuf + strlen(inbuf) - 1) = 0;
if(is_blank_line(inbuf))
  continue;
if((ret = executecmd(inbuf, &soap)) < 0) 
  break; /* accept the quit command */
else if(ret == 0)
  continue; /* encount the error command */

}
return 1;
}

int executecmd(char *inbuf,  struct soap *p_soap)
{
char *result;
int n;
char **chargv;

if((n = makeargv(inbuf, BLANK_STRING, &chargv)) < 0){
printf("makeargv error\n");
exit(0);
}
if(!strcmp(chargv[0], "add") && n == 3){
soap_call_yb__add_list(p_soap, server, "", chargv[1], chargv[2], &result);
printf("%s\n", result);
return 0;
}
else if(!strcmp(chargv[0], "del") && n == 2 ){
soap_call_yb__del_list(p_soap, server, "", atoi(chargv[1]), &result);
printf("%s\n", result);
return 0;
}
else if(!strcmp(chargv[0], "gettel") &&  n == 2){
soap_call_yb__get_tel_by_name(p_soap, server, "", chargv[1], &result);
printf("%s\n", result);
return 0;
}
else if(!strcmp(chargv[0], "getname") &&  n == 2){
soap_call_yb__get_name_by_tel(p_soap, server, "", chargv[1], &result);
printf("%s\n", result);
return 0;
}
else if(!strcmp(chargv[0], "list")){
soap_call_yb__get_list(p_soap, server, "", &result);
printf("%s\n", result);
return 0;   
}
else if(!strcmp(chargv[0], QUIT_STRING)){
return -1;
}
else if(!strcmp(chargv[0], HELP_STRING)){
printf("The usage of the command:\n");
printf("\"add name tel\"     add new entry to address book.\n");
printf("\"del no\"           delete entry by its corresponding phone number.\n");
printf("\"getname tel\"      get name by the corresponding phone number.\n");
printf("\"gettel name\"      get phone number by name.\n");
printf("\"list\"             list the current entries in the address book.\n");
printf("\"help\"             get help.\n");
printf("\"quit\"             quit this client.\n");
return 0;    
}
else{
printf("Can not execute this command.\n input \"help\" to get usage of commands.");
return 0;
}
return 1;
}

您也可以像这样在终端中运行客户端：./client

您可以在系统上安装 gsoap 的位置找到许多 gsoap 示例。您会在安装文件夹中找到一个SAMPLE文件夹，以帮助您了解 gSoap 的不同应用。
