Problem with HTTP request

[alexob]

Please help me to understand how can I requst by HTTP, for example, Date from my VCR 470?

I set up the work through the command line (works fine)...

pi@raspberrypi:~ $ ebusctl r -f Date
14.10.2017

But when I trying to do HTTP request it does not work.

http://localhost:8888/data/470/Date
I got error "ERR_INVALID_HTTP_RESPONSE"
Port and Path by default.

pi@raspberrypi:~ $ ebusctl info

I think I do anything wrong, but what? Please help.
Also, I manually created folder /var/ebusd/html and and copied there the contents of the folder \ebusd-master\contrib\html (maybe it not right).

[john30]

the /var/ebusd/html folder is not necessary for using the HTTP API under /data/.
What do you use to retrieve from the HTTP port?
When I issue the command curl http://localhost/data/broadcast/datetime then ebusd sends an answer like this:

{
 "broadcast": {
  "messages": {
   "datetime": {
    "name": "datetime",
    "passive": true,
    "write": false,
    "lastup": 1507974612,
    "zz": 254,
    "fields": {
     "outsidetemp": {"value": 12.875},
     "time": {"value": "11:50:00"},
     "date": {"value": "14.10.2017"}
    }
   }
  }
 },
 "global": {
...
 }
}

Hi John, Thanks for your answer.
In my case it doesn't work.

pi@raspberrypi:~ $ curl http://localhost:8888/data/470/Date
ERR: command not found
^C
pi@raspberrypi:~ $ ebusctl r Date
16.10.2017
pi@raspberrypi:~ $

I tried to enter url in the command line: "curl http://localhost:8888/data/470/Date" and in the browsers.
I got "ERR: command not found". But it work when I enter "ebusctl r Date"

The command Date present in the command list. I saw it after this:

pi@raspberrypi:~ $ ebusctl find
470 ACTOstorDetected = no data stored
470 actoSTOROPMode = no data stored
....
470 currenterror = no data stored
470 Date = 16.10.2017
470 DcfIsValid = no data stored
470 DisplayedHc1RoomTempDesired = no data stored
470 DisplayedHwcStorageTemp = no data stored
470 DisplayedRoomTemp = no data stored
470 EepromUpdateActive = no data stored
....

Maybe I should to copy csv files (like bai.csv etc) to other folder. Look like the it can not find the files with commands.

[john30]

please post the result of curl http://localhost:8888/data/470/Date?raw&write&def&full/verbose
the csvs are already loaded as otherwise the message would not be available through ebusctl find.
could you check if two ebusd services are running? ps aux|grep ebusd

Yes, csvs loaded I think

[john30]

you need to escape the & char in the request or put everything in quotes:
curl 'http://localhost:8888/data/470/Date?raw&write&def&full/verbose'

sorry, typo:

Hello John,
How can I change the Http Port to 8889 for example?
As I see from wiki, port for command line is 8888 (by default), therefore when I called "curl http://localhost:8888/data/470/Date" I tried to get data with incorrect port.

As I understand, for Http requst, I should use other port. By default HttpPort = 0. So, I should change the port for activate Http functionallity, right?

My ebusd is working as a service, I started it as

pi@raspberrypi:~ $ service ebusd start

I tried to change HttpPort with

pi@raspberrypi:~ $ ebusd --httpport=8889

but now after run command

pi@raspberrypi:~ $ curl http://localhost:8889/data/470/Date
curl: (7) Failed to connect to localhost port 8889: В соединении отказано

got the error "Connection refused"

Please, give me instruction how do you start work with Http step-by-step and what the settings you did.

Thanks.
(sorry for my English) :)

[john30]

okay that explains it. you have to active the ebusd http port by adding e.g. "--httpport=8889" to /etc/default/ebusd

[alexob]

Thank you, John.
It work now!

I changed line to
EBUSD_OPTS="--scanconfig --httpport=8889"

[john30]

ok great
