错误34;套接字编程中的结果太长

Question

我是套接字编程的新手。我想写一个简单的客户端服务器程序，但是当我运行它时，我得到一个（“error34：结果太长”）在接收function.i将不胜感激，如果你能帮助我。我该怎么办？

Server代码：

#include <stdio.h> 
#include <stdlib.h> 
#include <errno.h> 
#include<winsock2.h> 
#include <fstream> 
#include <sys/types.h> 
#ifdef __WIN32__ 
# include <winsock2.h> 
#else 
# include <sys/socket.h> 
#endif 
#ifdef __WIN32__ 
# include <winsock2.h> 
#else 
#include <netinet/in.h> 
#endif 

int main(){ 
WORD wVersionRequested; 
WSADATA wsaData; 
SOCKET intSocket,intRSocket; 
struct sockaddr_in recServer,recClient,recSin; 
int intErr,intLen,Message; 
char charbuffer[256]; 

    wVersionRequested=MAKEWORD(2,0); 
    if(WSAStartup(wVersionRequested,&wsaData)!=0) 
    { 
    printf("Error on initializing"); 
    exit(1); 
    } 

    recServer.sin_addr.S_un.S_addr=inet_addr("127.0.0.1"); 
    recServer.sin_family=AF_INET; 
    recServer.sin_port=htons(3666); 

    intSocket=socket(AF_INET,SOCK_STREAM,0); 
    if(intSocket ==(unsigned) -1){ 
    printf("\n::Error On Create Socket::%d \n", errno); 
    perror("socket"); 
     exit(1); 
    } 

intErr=bind(intSocket,(struct sockadd*)&recServer,sizeof(recServer)); 
    if(intErr == -1){ 
     printf("\n::Error On the Call bind Function::\n"); 
     exit(1); 
} 

else{ 
     printf("Waiting for incoming connection");} 

for(;;) 
{ 

    intErr=listen(intSocket,SOMAXCONN); 
    if(intSocket ==(unsigned) -1){ 
     printf("\n::Error On the Call listen Function::\n"); 
      exit(1); 
    } 

    intLen=sizeof(recClient); 
    intErr=accept(intSocket,(struct sockaddr *)&recClient,&intLen); 
    if(intSocket== (unsigned) -1){ 
    printf("\n::Error On Connection::\n"); 
    exit(1); 
    } 



     do{ 
     intErr=recv(intSocket,charbuffer,sizeof(charbuffer),0); 
     if(intErr==(unsigned)-1) 
     { 
     printf("\n::Error On Recev Data:: %d\n" , errno); 
     perror("recv"); 
     exit(1); 
     } 
     } 
    while(Message=recv(intSocket,charbuffer,sizeof(charbuffer),0)); 

     Message=recv(intSocket,charbuffer,sizeof(charbuffer),0); 

     Message=send(intRSocket,charbuffer,strlen(charbuffer),0); 
      system("pause"); 



    std::ofstream output_file("Recieved Data.txt", std::ios::out); 

      if(!output_file) 
    { 
     printf("file can not open"); 
     exit(1); 
    } 

    else 
    { 
     output_file << charbuffer; 
    } 
    return 0; 

} 

}

在服务器代码你打电话给你传递给listen()在插座上recv()和accept()。

accept()返回代表连接客户端的套接字。这是您应该传递给send()和recv()的套接字。

此外，您在服务器代码中的do/while循环是一团糟。你究竟想要做什么？
