HTTP Backend Connectors

[Quentintin]

Hi,

I would like to know if you plan to add HTTP/HTTPS Backend connectors ? It will be awesome if you can provide it. 👍

Thanks for response :)

Simple connector making one HTTP/S request per frame, without support for downlinks is quite easy. The reason why it's not implemented is that I was not sure if anyone needs such simple thing, because there may be a lot of variations (HTTP GET vs. HTTP POST and various content types).

What are your needs? Where are you connecting to?

[Quentintin]

I created backend to receive messages from Sigfox and LoRaWAN Operators. Most of them provides callback methods with HTTP/S. My backend is a part of a Web Platform to manage IoT devices. I implemented HTTP restAPI used by users and Operator's backend to push messages. That's why I need this.

If it simple for you, you should implement it because i'm pretty sure lot of people will ask you for that connector.

So far you are the first asking for this :) but I can do that. Do you have some examples how this HTTP API often looks like? What URI, Content-Type, Body?

[Quentintin]

The perfect callback for me is POST method :

• URL (can content variables {devEUI}, {devAddr}, {...})
• Content-type : application/x-www-form-urlencoded or application/json
• Headers : For authentication - Authorization
• Body : Editable fields with variable, or static content

Firstly you can do easy way with static url/body, and later allow custom fields.

Sorry for my english :/ And thank you again

[gotthardp]

Thanks. Will do. :-)

Some news about this topic, we are also very interested by this connector ?

[gotthardp]

Not yet, but the more people are interested the higher priority it gets. ;-)

Is your view on a perfect HTTP callback the same as described above, or you have some other needs?

[stephanedavid]

Exactly the same view. Thanks

@Quentintin @stephanedavid @mkpuig I started to work on this. In the 'master' branch there is an experimental implementation already available (which you can try): you can create an HTTP(s) connector and define some "Published Topic". The content-type is determined based on the handler format.

If you encounter some error, just let me know.

I am still not satisfied with the error handling, so in case an error occurs the system may crash in a not so nice way. This will be fixed in the coming week(s).

Hello, I would like to test the server version with REST commands for txframes. Can you send me the compiled version? I would also like to know when it is possible to expect the 0.4.8 version? It would be really great to get it.

[gotthardp]

Hello. I want to do some more testing to make sure I didn't destroy anything, but hope to release 0.4.8 today,

[gotthardp]

v0.4.8 released Feel free to open a new issue if something goes wrong.
