    Reading HTML files and Images from Website

    Maybe I am looking in the wrong place, but I was having trouble googleing this information.

    Basically, what I want to do is connect to a webserver and get a pages html and save it locally (also want to do this with images on the given page). Anyone point me in the right direction?

    Thanks.

    Try google or yahoo or another such search engine.

    Or post this question in the Networking board.

    Hi
    Nowadays i am working on such an application that retrives the HTML pages from a web server This is your luck day, but for images, i have no idea!
    Just use ordinary socket functions. And don't forget to set the server's port to 80. So, your sockaddr_in structure will seem like this

    char *msg="GET /\n";
    struct sockaddr_in server;
    ....
    ....
    server.sin_family=AF_INET;
    server.sin_port=htons(80); /* for HTTP */
    server.sin_addr.s_addr=inet_addr("server_IP_addres ");
    memset(&(server.sin_zero),'\0",8);

    connect(....);

    send(sockfd,msg,strlen(msg),0);

    and save the received data into a ASCII file which has "html" extension. This is the way I use....
    The "GET /" specifies the page that you want to get.For example "GET /foo/tux.html" will get the http://www.your_server.com/foo/tux.html. Get more information about HTTP specifications from google.

    http://www.gnu.org/software/wget/wget.html

    Or if you want to write some code yourself
    http://curl.haxx.se/

    Just some extra points for not mentioning your OS and Compiler in your vacuous request.
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.
    I support http://www.ukip.org/ as the first necessary step to a free Europe.
