Bank Interface Thread: Development

[Erik Mortis]

So... I've been researching.

interface.php would be the page. It would require a HTTPS connection (I might just make this bank wide...)

To use it just send a POST request, JSON encoded associative array named 'transfer' with the fields, username, password, destination, amount, reason and apikey.

I'm going to need to make a bank utility to generate API Keys, linked to certain accounts.

the script will send back the key/value 'error' which will have 0 for success or a variety of error codes. You can do with it as you please. hmm... I need to figure out where to send the response too. I think there is a $_SERVER[] variable for that.

I'm new to this webpage talking to each other stuff across domains, so Ari if I don't seem to know what I'm talking about let me know. I'll be paying you for consulting help btw.

And at this time I'm going to ask someone to pay 500 for this feature. Don't care who pays, but someone will have to pay for it. I might even talk to the SCUE about charing for API keys.

[Thadeus Laing]

I'll pay it. Sending the money.

Just 'echo' it It will do - whether you're using file_get_contents with stream contexts or just curl.

[Erik Mortis]

ok..why am I asking for an associative array..it'll come out as such.

Just encode an associative array with the following key/value pairs to the field name "transfer":
'username': (The source account)
'password': (Source password)
'amount': (funds to move)
'destination':(account to move money into)
'reason': (The reason the bank is to give in the log)
'apikey': (the apikey that grants access to the bank)

This should give me the JSON similar to: {"username":"someone","password","asecretword","amount":"123.45","destination":"someoneelse","reason":"whywetookit","apikey":"areallylongstring"}

From here I'll just call $_POST['transfer'] where ....wait.... I'm confused. I still need to specify the POST['transfer'] variable name.. well..technically that's on your end, but I still need to understand it.

[Erik Mortis]

Okey... I see how that would be done.

transfer=(JSONencodeddata)


moving on..How do I respond that things worked or failed..Do I just use header()? Or does that just go to the clients browser... I think I read something about just using header to respond. ...how would they read that... hmmm...

[Erik Mortis]

hmm...so... maybe it would just be easier to let people pass things as individual POST fields.. as in from a form... but I double people want to put thier API key in a hidden field, that can be seen in the source of their pages... so.. yeah.. no..

How do I know where to respond....?


OH here's what I was reading the other day!

POST it JSON encoded to interface.php on the bank server as field "transfer"

I do what I do with it.. and:

Code: Select all

$encoded = json_encode($response); //Where response is my response codes and stuff I haven't worked out. 
header('Content-type: application/json');
exit($encoded);

[Erik Mortis]

welll...shit... transfer_funds() throws internal error messages... meaning calling back header()will fail... So I have to rewrite bank_error() so they aren't visible...but... I need them visible.... Well.. maybe it's time to start logging error messages... or remove all those bank_error() functions...

Damn it.... I don't want to remove them..but I can't leave them.... problems problems...

[pawelabrams]

Have you considered using ob_* functions? They provide a way to catch everything that is echo'ed without actually sending it to the client. You can still fetch the bank errors and save them to a variable, log them and stuff...

Code: Select all

exit($encoded);

And yeah, you could just echo $encoded; provided you don't have any code left after that. And I suppose you don't.

[Erik Mortis]

I know not of these ob_*() functions. I will soon.

[pawelabrams]

http://www.php.net/manual/en/ref.outcontrol.php - the manual covers pretty much everything about them I suppose that all you need is ob_start and ob_get_clean !

[Erik Mortis]

Oh.. that is nice...
