Allows you to download web pages or files without blocking the game.

I got three questions:
1. I know that in order to download a file I need to write

rq=httprequest_create();httprequest_connect(rq,"mywebpa.ge/file.exe",0);

but how do I specify the download destination?
2. How do I check if the download has been canceled because of e.g. lost connection to internet or something else?
3. How do I check when the download has finished?

You have to store it on a buffer, and then drop the buffer onto a file:

// Step event, assuming your code is on the create event or it has been called before this:
if httprequest_exists(rq)
{
    httprequest_update(rq);
    state = httprequest_get_state(rq);
    if state = 5
    {
        show_message("Download failed");
        httprequest_destroy(rq);
    }
    if state = 4
    {
        buffer = buffer_create();
        httprequest_get_message_body_buffer(rq,buffer);
        buffer_write_to_file(buffer, "C:\file.exe");
        buffer_destroy(buffer);
        show_message("Download complete");
        httprequest_destroy(rq);
    }
}

httprequest_get_state seems to return 4 way too early - it says Download complete when only 288 bytes out of 7kb are downloaded

edit: I simply needed to add httprequest_set_request_header(rq, "Connection", "keep-alive",true); so that the request doesnt die after the initial connection

new question: What will happen if I try to get the Content-Length header if it doesnt exist?

Did you try to read the message body to find out what pixdrop says?

If I understand how to use your dll function (it returns the message body from the website?) then PixDrop returned nothing.

Also, are you sure the phone number should be entered without the '-' characters?

I'm pretty sure it is supposed to be without. TxtDrop definitely is so I doubt they would be different. In any case I have been testing both just in case with no success.

Normally you shouldn't have to do this, the web server should close the connection only after the file has been downloaded completely. Setting 'connection' to 'keep-alive' means the server won't close the connection even when the transfer is complete, so you can send a second request with the same connection (the DLL doesn't support this though). I'm surprised this works for you ...

new question: What will happen if I try to get the Content-Length header if it doesnt exist?

The function will return an empty string.

@Buff-Robotix: I don't know why it doesn't work. Maybe they are blocking your request because they don't like automated requests?

Possibly but I doubt it, its a very simple html based site.
They also have a similar upload based picture sending site http://www.pixdrop.com/uploader.php I think I will try this one.

Is there any way to change the version of http on the header? so it looks like 'GET /file.php HTTP/1.1' (instead of the current 1.0)

[Maarten Baert]

No, because if you did that the server would send a HTTP 1.1 response, which the DLL doesn't support. But why do you want HTTP 1.1 anyway? You can still send HTTP 1.1 headers even if the request says HTTP/1.0 (that's just the version for the response).

[Manuel777]

Because im triying to comunicate with a server wich only supports 1.1, it checks the version on the header to accept only 1.1 requests.. guess ill have to use js for this one

Or just build the requests yourself using the socket functionality of this DLL?

How would you check to see if there is internet connectivity before creating an http request and trying to connect?

I have this problem where if the internet is working, then the game runs fine. However, if the internet goes down then the game locks up. (which is why i want to test for connectivity before trying to connect)

Is there any way to make the dll use port 21 instead of 80?
I need to use ftp

The game shouldn't lock up, it should just fail to connect. If it locks up, there's probably something wrong with your code. Can you post the relevant code?

The name of the dll is 'Http Dll 2' for a reason: it supports HTTP, not FTP . Just changing the port won't work. There are other DLLs for FTP though.

[Timothyfoster]

Thanks for the reply, I realise now that It wasn't locking up the game... it was just taking a few seconds to respond which caused the game to stop.
btw "the machine" is really cool.. the physics are thought out well.. good job.

What might be a reason Http Dll 2 to be failing to create any sockets under windows 7 and in the same time to create them and run fine under windows xp?

I don't know, I'm using Windows 7 and it runs fine. Maybe it's a firewall setting?

[Maarten Baert]

Update: I've added UDP support, and there's also a small change to the way sockets work. socket_update has been replaced with socket_update_read and socket_update_write. This should make it easier to use the DLL correctly. Now your message loop should look like this:

// SERVER: step event of obj_player
// CLIENT: step event of obj_controller
var s;

/* (optional) send messages here */

socket_update_read(socket);

while socket_read_message(socket, global.buffer) {
    /* send and receive messages here */
}

/* (optional) send messages here */

s = socket_get_state(socket);
if s=4 {
    
    /* the connection was closed:
       SERVER: destroy this instance of obj_player.
       CLIENT: end the game or go back to the menu. */
    
    exit;
}
if s=5 {
    
    /* an error has occurred, the connection was lost:
       SERVER: destroy this instance of obj_player.
       CLIENT: display an error message, end the game or go back to the menu. */
    
    exit;
}

socket_update_write(socket);

You can also put socket_update_write(socket); in the end step event if you want. This makes it easier to make sure all messages are written before socket_update_write is called.

your dll is the best network dll of this community, i speeded up my work thanks to HTTP2 Dll, Great job Maarten Baert!

I've been looking for a potential replacement for 39dll as I have found it is limiting for what I need to do.
So far the most potential i've seen is Net39 and this one. I tested it out both with using GM and C++ and it runs amazing and is easy to use

Im so glad I found this I may even consider upgrading my game and server in the next dev cycle
Theres a few other features I may add in as well

Nice Work!!

[oslash]

im trying to replace 39dll from my game but this is really buggy

i dont know why but when i change things that shouldnt do any changes, i have a diferent result

for example i used

a=buffer_read_uint8(global.buffer);
switch (a)
{
//actions
}

it keep reading the first message received (always receiving the login message, even when using buffer_clear)
but when i used

switch (buffer_read_uint8(global.buffer))
{
//actions
}

it worked normally
