我是套接字编程的新手。我正在尝试创建一个HTTPS网站的套接字。套接字已成功创建,并且我能够使用连接进行发送并发送标头...但是作为来自recv()的响应,我没有标头响应,也没有得到-1 ...程序只是被阻塞了。该站点为https ...打开了端口443。
#include<iostream>
#include<cstring>
#include<sys/socket.h>
#include<netdb.h>
using namespace std;
int main()
{
int status;
struct addrinfo hostInfo;
struct addrinfo *hostList;
memset(&hostInfo, 0, sizeof(hostInfo));
hostInfo.ai_family = AF_INET;
hostInfo.ai_socktype = SOCK_STREAM;
cout<<"Setting up the structs..."<<endl;
status = getaddrinfo("academics.vit.ac.in", "https", &hostInfo, &hostList);
if(status == 0)
{
cout<<"Success"<<endl;
//cout<<hostList->ai_addr<<" "<<hostList->ai_socktype;
}
else
{
cout<<"Failled!";
}
int socketd;
socketd = socket(hostList->ai_family, hostList->ai_socktype, hostList->ai_protocol);
if(socketd == -1)
{
cout<<"Socket Error\n";
}
else
{
cout<<"Socket Success\n";
}
cout<<"Connecting\n";
status = connect(socketd, hostList->ai_addr, hostList->ai_addrlen);
if(status == 0)
{
cout<<"Success"<<endl;
//cout<<hostList->ai_addr<<" "<<hostList->ai_socktype;
}
else
{
cout<<"Failled!";
}
cout<<"\nSending Header\n";

}
cout<<"Waiting to recieve data\n";
char rmsg[1000];
msgSize = recv(socketd, rmsg, 10, 0);

提前致谢 :)
最佳答案
您应该将套接字设置为非阻塞(使用fnctl()),然后查看recv()返回的内容。
还要检查errno。那应该给您更多信息。
参见man 2 recv()@ http://linux.die.net/man/2/recv。
关于c++ - 在C++中recv()没有收到https请求的数据,我们在Stack Overflow上找到一个类似的问题:https://stackoverflow.com/questions/17242701/
