hey Guys - I seem to be having an issue with getting proper POST requests to work...

I can connect on localhost, but any remote connect does not work, e.g. on the testnet or on raspi in my local net ...

I know I am missing something obvious here, but as I say, I am a science programmer, and not so much a web programmer

Do I have to use http or https?
 
as far as I understand, the entry '*' in the conf should be enough to connect



#### API SERVER ####

# Accept http/json API requests.
nxt.enableAPIServer=true

# Hosts from which to allow http/json API requests, if enabled.
nxt.allowedBotHosts=*
 
# Port for http/json API requests.
nxt.apiServerPort=7876


In my localnet, I can connect to my raspi at http://192.168.178.24:7876

when I try https I get: requests.exceptions.SSLError: [SSL: UNKNOWN_PROTOCOL] unknown protocol (_ssl.c:548)


when I try testnet, the python just dies - what is different on the testnet???

you have to specifically enable SSL.  and when you do that, you MUST use SSL.  also when you do that, I believe you MUST EITHER create your own self-signed cert or you must purchase a signed cert.  I dont believe the NRS version  comes with the old 2008 SSL cert it used to come with
  look in wiki howto for guide on certs

thanks for the hint - I created a cert according to the wiki, but the most pat is for running a node yourself and how to set up NRS to ACCEPT connections.

So now I am trying to get my requests(POST) to use the cert to connect to the testnet - I'll keep trying


sorry guys - I am not getting anywhere. is the testnet API connect running on port 6876?

do I have to use a local cert that I supply in my local nxtClient folder?

 I don't want to clog up the main thread, so I'll try to posting here - maybe some of you other client devs can give me a few hints:
 
Am I correct with assuming that to connect with the testnet, I have to use and port 6876 ? as in my local net it is http://192.168.178.24:7876/ , but what confuses me is that in the local net it is http - surely that is set in the conf file, and a node open to the net will not

use http - but then again I am stuck with the problem of constructing proper POST requests. Does my requests lib have to provide a user cert? There are hooks for that in the lib..

seems most of my issues were related to the testnet  -  debugging can also be often a learning experience - unpleasant, but now pain no gain

Do you devs yet have any ideas on the APIs that will be involved in leasing effectiveBalance?  In order to assist with remediation, hopefully there will be something more than just leasing and recalling your effectiveBalance.  From the leasee's perspective, upon generating a block and receiving fees, it will be necessary to determine each individual effectiveBalance it is leasing as of 1440 blocks before the pool's generated block, and to then make sure that each effectiveBalance never went down during the next 1440 blocks.

So Ill propose an API to allow an account to request a list of all accounts leased out to it as of a certain block.  Or if you are feeling generous, with this info, also provide the effectiveBalance of each account at that certain block.  Or possibly even something similar to guaranteedBalance that lists a guaranteedEffectiveBalance of 1440 blocks as of a certain block of all effectiveBalance's that you are leasing.  Now that would be IDEAL

Is this the best place for all information associated with the API?  Is there a better resource for all updates and calls to the API?

Hello.

There is also another thread regarding NXT API.
Check this one:
https://bitcointalk.org/index.php?topic=406839.0

or maybe is better that you go to the nxt forum at
https://nxtforum.org/

Almost all NXT discussion has moved there.

Thank you.  I found the info on the Wiki (doh!)

Hey guys, what is the POST equivalent of this call:

curl "http://my-host.com/nxt?requestType=getAccountId&secretPhrase=whatever-is-clever"


I've tried:

curl --data-binary '{"requestType": "getAccountId", "secretPhrase":"whatever-is-clever"}' http://my-host.com/nxt

but it does not work

[kwilliams]

Never mind, found it.It turns out I just had to change the request type to POST, the parameters still travel via URL (this is silly). In case you wonder the full command is:

curl --data-binary '' "http://my-host.com/nxt?requestType=getAccountId&secretPhrase=whatever-is-clever"

ah. I backtraced and found where/how I did a copy/paste error.

ok so the system doesnt prevent you from doing anything dumb.  will this be fixed in the future?

And it really would be useful to see the balance of assets, not just of NXT.

Core doesn't prevent from doing dumb things, client soft is supposed to do it.

I'll add asset balance API.

Was this ever done?

Go here: http://localhost:7876/test and look for "getAccount".

I created one, just finishing browser support https://github.com/pocesar/node-nxt-api
