Hey, i had tried the HTTP api in computercraft, it is working fine to websites like twitter, youtube and google. I need to connect to this website:
http://textuploader.com and i can't…. I get nil response from the webstie. Anyone knows what's up?
BTW: The http api needs some in depth tutprials, this has a lot of potential and i think the wiki info and some forum posts are not enough.

I can connect to it without any issues. You should try again. Or perhaps it's a certain page you're having trouble with and not the actual site? It would help if you posted the exact URL you're connecting to.

Ah yes, I just tried it in the actual game. I was using cclite before. It seems that the site doesn't want connections from Java. To solve it, just pretend you're not connecting from Java by specifying a user agent.
local response = http.get("http://textuploader.com", { ["User-Agent"] = "YourProgramsNameOrSomethingThatIsntJava" })
print(response.readLine()) --# Should work now.
response.close()

Yup, it worked.
How did you know the problem was about java? Why this webstie and not google? And what are those arguments (User-Agent)? It seems usefull and i would like to learn mor about it. Sorry for so many question, i guess i am a curious person. Thanks :D/>

Some websites like to block connections from Java clients. I have no idea why they do this but they do.
User-Agent is a HTTP header, which tells a website what program the connection was established with (e.g. the browser). You can find a list of HTTP headers
here.

Ok thnks :D/>
Quick note: it wont work in ccemu. Maybe the version its too old? I guess i coul try to get the http api from a newest version of computercraft into the ccemu rom, but i guess the problem isn't in the http api…
Edit: I just realized there is no http api… lol stupid me XD

Yes, the HTTP API is probably too old. You should be using the new version of CCEmu,
CCEmuRedux, anyway.

Ok, i am having some troubles.
I want to connect to this page:
http://api.textuploader.com/v1/postsIn the browser it works, but when i try to do it in computercraft:
This one i get the same error as before (attempt to index ? (a nil value)):
local response = http.get("http://api.textuploader.com/v1/posts", { ["User-Agent"] = shell.getRunningProgram() })
This one (wich is the one i want to use) just freeze (it loops):
local response = http.post("http://api.textuploader.com/v1/posts","X-TextUploader-API-Key:"..key, { ["User-Agent"] = shell.getRunningProgram() })
I want to get the response from the posts page and i can't get anything…

The former will respond with 401 Unauthorised, which makes ComputerCraft return nil, so that's normal.
Anyway, the main issue lies in the latter piece of code:
The documentation says: "To identify yourself, you send the following HTTP header with your API key". Which means that the second argument you're passing has to be inside the header table.

For that i skip the second arument of the http.post and do something like:
local response = http.post("http://api.textuploader.com/v1/posts",_, { ["User-Agent"] = shell.getRunningProgram(), ["X-TextUploader-API-Key:"] = key })
?

You don't need a colon here:
["X-TextUploader-API-Key:"]
The second argument is required in http.post, so you can't skip it. Since you don't need post data, just use http.get.

Hmm, that should work. I don't have any experience with TextUploader, so I can't help you there, especially because ComputerCraft doesn't give you much detail about what exactly fails. I'm assuming it's the authorisation that fails (the api key in particular) and not the actual connection, so you should check the TextUploader docs to see if you're missing anything.

No, ComputerCraft returns nil when something doesn't respond with a 200 OK response.
