gsoap：实现线程池处理时获取到客户端的ip

问题：

在使用线程池处理客户端请求时发现不能获取到客户端的ip！

原因：

    由于在server_loop注循环中只把连接字sock加到queue队列中，并没有客户端IP，所以每一次queue回调函数只能取得sock连接字，没有客户端的ip

解决方法：

    在将sock加入queue队列的同时把ip也加入到ips队列中，ips队列的长度和queue相同，而且存的数据下标要相同，取sock处理时也把IP取出来，即可得到了客户端IP

步骤：

    定义全局保存IP地址的变量

[cpp] view plaincopyprint?

1. static unsigned long ips[MAX_QUEUE];  

    static unsigned long ips[MAX_QUEUE];

    修改 enqueue函数

[cpp] view plaincopyprint?

1. int enqueue(SOAP_SOCKET sock,unsigned long ip)//添加ip的参数  
2. {  
3.         int status = SOAP_OK;  
4.         int next;  
5.         int ret;   
6.         if ((ret = MUTEX_LOCK(queue_cs)))  
7.                 fprintf(stderr, "MUTEX_LOCK error %d\n", ret);  
8.         next = (tail + 1) % MAX_QUEUE;  //1000   
9.         if (head == next)  
10.         {      
11.                 /* don't block on full queue, 
12.                  * 队列已满，return SOAP_EOM */  
13.                 status = SOAP_EOM;  
14.         }      
15.         else   
16.         {      
17.                 queue[tail] = sock;  
18.                 ips[tail] = ip;  //保存ip   
19.                 tail = next;  
20.                 if ((ret = COND_SIGNAL(queue_cv)))  
21.                         fprintf(stderr, "COND_SIGNAL error %d\n", ret);  
22.         }      
23.         if ((ret = MUTEX_UNLOCK(queue_cs)))  
24.                 fprintf(stderr, "MUTEX_UNLOCK error %d\n", ret);  
25.         return status;  
26. }  

int enqueue(SOAP_SOCKET sock,unsigned long ip)//添加ip的参数{        int status = SOAP_OK;        int next;        int ret;         if ((ret = MUTEX_LOCK(queue_cs)))                fprintf(stderr, "MUTEX_LOCK error %d\n", ret);        next = (tail + 1) % MAX_QUEUE;  //1000        if (head == next)        {                    /* don't block on full queue,                 * 队列已满，return SOAP_EOM */                status = SOAP_EOM;        }            else         {                    queue[tail] = sock;                ips[tail] = ip;  //保存ip                tail = next;                if ((ret = COND_SIGNAL(queue_cv)))                        fprintf(stderr, "COND_SIGNAL error %d\n", ret);        }            if ((ret = MUTEX_UNLOCK(queue_cs)))                fprintf(stderr, "MUTEX_UNLOCK error %d\n", ret);        return status;}

    添加dequeue_ip()函数

[cpp] view plaincopyprint?

1. unsigned long  dequeue_ip()  
2. {  
3.         unsigned long ip;  
4.         int num=0;  
5.         if(head == 0)  
6.             num = MAX_QUEUE - 1;  
7.         else   
8.             num = head -1;  
9.         ip = ips[num];  
10.         return ip;  
11. }  

unsigned long  dequeue_ip(){        unsigned long ip;        int num=0;        if(head == 0)            num = MAX_QUEUE - 1;        else             num = head -1;        ip = ips[num];        return ip;}

修改queue回调函数函数

[cpp] view plaincopyprint?

1. void *process_queue(void *soap)  
2. {  
3.         struct soap *tsoap = (struct soap*)soap;  
4.         for (;;)  
5.         {  
6.                 tsoap->socket = dequeue();  
7.                 tsoap->ip = dequeue_ip();//获取相应的ip地址  
8.                 if (!soap_valid_socket(tsoap->socket))  
9.                 {  
10. #ifdef DEBUG   
11.                         fprintf(stderr, "Thread %d terminating\n", (int)(long)tsoap->user);  
12. #endif   
13.                         break;  
14.                 }  

void *process_queue(void *soap){        struct soap *tsoap = (struct soap*)soap;        for (;;)        {                tsoap->socket = dequeue();                tsoap->ip = dequeue_ip();//获取相应的ip地址                if (!soap_valid_socket(tsoap->socket))                {#ifdef DEBUG                        fprintf(stderr, "Thread %d terminating\n", (int)(long)tsoap->user);#endif                        break;                }
