Simple example to convert CURL/JSON to Python?

Haven't done a lot with Python yet, but I have an external device that I would like to control.

I have sample integration commands from the manufacturer that are shown as CURL scripts with JSON data.

Is there a cookbook reference or sample files that show how I can convert the samples from CURL/JSON to Python scripts or is there a direct way to run the existing script with Indigo?

I can easily cut/paste the parameters in the CURL command line, but was hoping not to have to learn Python (yet) and find a simple "connect-the-dots" kind of solution where I can cut/paste some Python or scripting code and not have to delve into the full workings of it (yet).

At the basic level, I just want to issue commands to the device and I don't need to process any returned data - not even status. At least for the proof-of-concept tests.

Should be very straightforward. Post a copy of a command you want to execute and we'll cobble together an example script

This goes in an "Execute Python Script" action.
Code: Select all
import requests
requests.get(<<put url that use use with curl here>>)

Re: Simple example to convert CURL/JSON to Python?

Here's an example of a curl command I would like to send:

Code: Select all
$ curl -X POST ‘http://localhost:47147/api/v1/sendcommands' -X POST -d ‘{ "delay"
: "1000", "commands" : [ { "type" : "command", "params" : { "command" : "VOLUME
UP", "device" : “2DCCA135-4264-41B1-842B-8118337C71DE”, “repeat” : “constant” } }
] }’
{
"status" : "success",
"data" : {
"session" : "96F4C281-B34D-47D4-9097-EA80874FAFE4"
},
"code" : 200
}

Here's the reference for what you want to do: http://docs.python-requests.org/en/mast ... uickstart/

That's an interesting one because the data you're posting is actually a JSON string.

So something like this, I think:

Code: Select all
payload =‘{ "delay" : "1000", "commands" : [ { "type" : "command", "params" : { "command" : "VOLUME UP", "device" : “2DCCA135-4264-41B1-842B-8118337C71DE”, “repeat” : “constant” } } ] }’

requests.post("http://localhost:47147/api/v1/sendcommands", json=payload)

Thanks!

I'll take a look.

(yeah, the JSON stuff is why I asked. Looked more complex then just a "one liner" like the Indigo HTTP commands.)
