存根/骨架编译器有没有办法生成线程服务（即通过为每个请求生成一个线程或通过线程池）或者我必须手动添加soap_copy（），pthread_create（）...

我知道——根据常见问题解答和用户指南 7.2.4——gSOAP 是线程安全的，并且确实支持多线程服务。但是，使用 soapcpp2 -i 标志我最终得到

int DummyService::run(int port)
{   
    if (soap_valid_socket(bind(NULL, port, 100)))
    {   
        for (;;)
        {   
            if (!soap_valid_socket(accept()))
                 return this->error;
            (void)serve();
            soap_destroy(this);
            soap_end(this);
        }
    }
    else
        return this->error;

    return SOAP_OK;
}

有什么提示吗？

这可能不是对您的特定请求的直接处理，但它与我能找到的一样接近......（摘自http://www.cs.fsu.edu/~engelen/soapdoc2.html#sec:mt）

以下示例说明了使用线程通过在单独的线程中处理新请求来提高服务质量：

#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;
}

注意：代码不会在程序终止时等待线程加入主线程。

在上面链接中引用的文档的同一区域中还有其他线程信息。它至少可以为您寻找解决方案提供一个起点。
