Read from raw paste in c++

Question

So, i was wondering if it is possible(most likely without the useage of a libary) to read the raw paste/or better say the html code of a website using c++. All the codes/tutorials i found wasn't really helpful, so i was wondering if some of you could help me out. I want to read of of this link:

http://pastebin.com/raw/93HGpGG0

that code seems to be what im looking for but im missing Network and Http class...

bool Http::Connect(YString addr)
{
    _socket = Network::CreateConnectSocket(addr, 53); // 53 is the port
    return _socket != INVALID_SOCKET;
}
int iResult;
SOCKET ConnectSocket = INVALID_SOCKET;

// holds address info for socket to connect to
struct addrinfo *result = NULL,
    *ptr = NULL,
    hints;

ZeroMemory(&hints, sizeof(hints));
hints.ai_family = AF_UNSPEC;
hints.ai_socktype = SOCK_STREAM;
hints.ai_protocol = IPPROTO_TCP;  //TCP connection!!!

                                  //resolve server address and port
iResult = getaddrinfo(addr.c_str(), std::to_string(port).c_str(), &hints, &result);
if (iResult != 0)
{
    printf("Network::CreateSocket failed with %s as addr, and %i as port.\nError code: %i.\n", (char*)addr.c_str(), port, iResult);
    return INVALID_SOCKET;
}

for (ptr = result; ptr != NULL; ptr = ptr->ai_next) {

    // Create a SOCKET for connecting to server
    ConnectSocket = socket(ptr->ai_family, ptr->ai_socktype, ptr->ai_protocol);

    if (ConnectSocket == INVALID_SOCKET) {
        printf("Network::CreateSocket failed with error: %ld\n", WSAGetLastError());
        return INVALID_SOCKET;
    }

    // Connect to server.
    iResult = connect(ConnectSocket, ptr->ai_addr, (int)ptr->ai_addrlen);

    if (iResult == SOCKET_ERROR)
    {
        closesocket(ConnectSocket);
        ConnectSocket = INVALID_SOCKET;
        printf("Network::CreateSocket failed the server is down... did not connect.\n");
    }
}

freeaddrinfo(result);

if (ConnectSocket == INVALID_SOCKET)
{
    printf("Network::CreateSocket failed.\n");
    return INVALID_SOCKET;
}

u_long iMode = 1;
iResult = ioctlsocket(ConnectSocket, FIONBIO, &iMode);
if (iResult == SOCKET_ERROR)
{
    printf("Network::CreateSocket ioctlsocket failed with error: %d\n", WSAGetLastError());
    closesocket(ConnectSocket);
    return INVALID_SOCKET;
}
char value = 1;
setsockopt(ConnectSocket, IPPROTO_TCP, TCP_NODELAY, &value, sizeof(value));
return ConnectSocket;

Winsock 2 Reading text from a URL this was the post i got the coding from!

Hopefully someone can help me out im searching for this since may xD

Answer 1

Just use a simple HTTP GET Request with your socket:

GET /raw/93HGpGG0 HTTP/1.1\r\nHost: www.pastebin.com\r\n\r\n

You can use Boost socket library.And also you can use POSIX or winsock for create socket without any library:

Answer 2

You are asking for a possible solution without using any libraries. This solution uses a library but it is relatively easy:

Download libcurl and open libcurl.sln in Visual Studio. Choose whichever configuration you want (debug or release, static or dynamic, etc) and whether you want 32-bit or 64-bit, and build it. Once it finishesbuilding, read the compiler output in Visual Studio to see where it created your .lib file. Cut that lib file, then create a new folder somewhere outside of the source code named "curl", and create a folder inside of that one called "lib", and paste the library there. Then, go back to the source code folder, and copy the entire include folder over to the curl folder.

Now, and after making sure you included the library, it's time to test the it. Create a new Visual Studio project, and copy this source code into the main cpp file:

#include <stdio.h>
#include <curl/curl.h>

int main(void)
{
    CURL *curl;
    CURLcode res;

    curl = curl_easy_init();
    if (!curl) { return -1; }

    curl_easy_setopt(curl, CURLOPT_URL, "http://example.com");

    /* example.com is redirected, so we tell libcurl to follow redirection */
    curl_easy_setopt(curl, CURLOPT_FOLLOWLOCATION, 1L);

    /* Perform the request, res will get the return code */
    res = curl_easy_perform(curl);

    /* Check for errors */
    if (res != CURLE_OK)
    {
        fprintf(stderr, "curl_easy_perform() failed: %s\n", curl_easy_strerror(res));
    }

    /* always cleanup */
    curl_easy_cleanup(curl);
    return 0;
}

Result:
