Question

我对protobuf-c完全陌生
我正在尝试创建套接字连接并使用C语言在套接字上发送protobuf打包的消息
我将邮件打包在客户端代码中并发送到服务器。但是服务器无法接收打包的数据并将其解压缩
我的客户代码是

client.c

void *clientThread(void *arg)
{
Messages t_message = MESSAGES__INIT;
//while(1)
{
    void *buf;
    unsigned len;
    int32_t s32_send_status;

    t_message.name="anu";

    len=messages__get_packed_size(&t_message);
    buf=malloc(len);
    messages__pack(&t_message,buf);

    s32_send_status=send(gs32_clientSocket ,buf,len,0);

    //s32_send_status=send(gs32_clientSocket ,(unsigned char *)
            //(&t_message),sizeof(t_message) ,0);

    if(s32_send_status>0){
        printf("data send to server.\n");
    }
    else{
        printf("failed to send data to server\n");

我的服务器代码是

server.c

void *socketThread(void *arg)
{

Messages *t_message;
uint8_t buf[1024];
int32_t len;
// unsigned length;
//while(1)
{
    gs32_valread = read( gs32_new_socket,buf,len);

    if(gs32_valread==0){
         printf("disconnected\n");
         exit(1);
    }
    else if(gs32_valread<0){
         printf("error\n");
         exit(1);
    }
        else{

        t_message = messages__unpack(NULL,len,buf);

        printf("name=%s\n",t_message->name);

        messages__free_unpacked(t_message,NULL);
    }
    sleep(1);
    close(gs32_new_socket);
}
return NULL;
}

如果包装正确，如何在服务器端打开包装。如果有人知道这个答案，请帮我解决。谢谢
