Unix C++ simple server question: sending data back to browser -

-

I have written in a simple Unix server C ++ which just waits for an incoming connection, and then when a connection If installed, sends the requested data to display in the customer's browser. I have everything except work to send the data to the customer.

    1. I started the server and set the port number (for this example I have 8181 I will use it).

    2. The client opens the browser and connects to my server and tries to retrieve test.txt to see.

    3. The server accepts incoming connections. Checks to see whether the file exists or not. If the file exists, then it sends the file to the browser.

    • My problem is that I am not sure how the data can be sent back to the browser. I am trying to use Unix system calls to accomplish this, because I believe everyone needs to get back the data.

    Now what I am doing, put the file in a four array buffer and then it is fed into writing (socket id, buffer, strollon (buffer)). When I check it, the server gets the file correctly and reads the data in four array buffers, but typing () command is returning an -1 error value every time.

    I want to receive it where the browser connects and then the text in the browser. Txt is enabled, as well as browser-supported image formats.

    Do read in buffer and then write buffer in a socket "section and just send the file directly to the browser? Here is a part of the code that I am working with now. 

      // Create and listen to the binding socket call () ... conn_socket = accept (socketInt, (struct sockaddr *) and caddr, (socklen_t *) And caddrLength); RecvInt = recv (conn_socket, requested file buffer, 1023, 0); if (recvInt> gt; 0) to check that the requestd file exists and co // This file reads that the four array "buffer" int writeInt = write (recvInt, buffer, strlen (buffer)); // it is not working

    Do anyone have any suggestions? If you want to post more code to me I would be happy to do this, but I believe the problem is in the code given above.

    Thank you for your time.

    when you say : 

      int writeInt = Write (RecvInt, buffer, Streln (buffer));

    The first parameter to write should be the socket to write - you are counting the letters returned by recv ()

    c# - How to capture HTTP packet with SharpPcap -

    -
    I would like to capture all incoming HTTP packets on my machine. To do this, I am using SharpPcap which is a WinPcap The cover is. SharpPcap works very well, but it captures TCP packets and what it wants to do for me is a very low level. Does anyone know how can I easily get full HTTP requests / reactions from all these TCP packets? Thanks SharpPcap is already able to capture the packet in the same way That's what the virus does (just in the code instead of the GUI). And you can either either parse them directly or you can put them in the drive in the common .pcap file format. The steps to parse the capture are: Open a connection at any time Loop a while Or start capturing using an event callback Parsing the raw packet for the type you want If you are reading .PPP dump files In addition to calling you an offline capture reader is almost the same, there is no need to select an interface, and you can set the majority There is no need to do the modes. All st...

    By using Wordpress I have created a multiple selection box so that users can select categories to exclude. When the page is initially loaded, I see my predefined default option.

    jquery - SimpleModal Confirm fails to submit form -

    -
    I am trying to confirm jQuery to show yes / no confirmation when I submit a form. I had modified (in the last list) to capture and block form submissions. However, it only works with jQuery 1.2.6, a recent upgrade stops 1.3.2, if yes is clicked, then by submitting the form. But I can not understand what is wrong / inconsistent in my code now. Demo (which works in both versions of a simple window.href implementation). $ (document) .ready (function () {$ ('input.delete'). Click (function (e) {e.preventDefault (); var target = $ (e .target); Confirm ("Really delete this event?", Function () {target.click ()});});}); How about something like this? The idea of ​​catching clicks (and fire!) On the submitted event is not click event. $ (document) .ready (function () {$ ('# myForm'). Submit (function () {var f = this; Confirm (" Remove? ", Function () {$ (f). Submit ();}) Return; Return the initial session;}}}}; Hope That this is som...
