Issue with JSONPATH from HTTP Binding error code 1010

Add-ons Bindings
1

Dear Community,

I’m kind of a rocket nerd and like to watch launches, so I’m trying to parse the JSON from here:
https://launchlibrary.net/1.4/launch/next/1

I’ve done this for a while, but recently I’m getting an error and I do not know what changed. I’m on the latest 2.5.x OH.

with the following http.cfg:

http:rocketlaunch.url="https://launchlibrary.net/1.4/launch/next/1"
http:rocketlaunch.updateInterval=3600000

and these items:

String RocketLaunchNextUTC	    "Launch Time UTC [%s]"          <flowpipe>          (gRocketLaunch) {http="<[rocketlaunch:300000:JSONPATH($.launches[0].net)]"}
String RocketLaunchNextMission	    "Mission [%s]"                  <settings>      (gRocketLaunch) {http="<[rocketlaunch:300000:JSONPATH($.launches[0].missions[0].name)]"}
String RocketLaunchNextRocket	    "Launcher [%s]"                 <rocket>        (gRocketLaunch) {http="<[rocketlaunch:300000:JSONPATH($.launches[0].rocket.name)]"}
String RocketLaunchNextPad	    "Pad [%s]"                      <movecontrol>   (gRocketLaunch) {http="<[rocketlaunch:300000:JSONPATH($.launches[0].location.pads[0].name)]"}
String RocketLaunchNextISO          "Launch Time UTC ISO [%s]"      <flowpipe>          (gRocketLaunch) {http="<[rocketlaunch:300000:JSONPATH($.launches[0].isonet)]"}
Number RocketLaunchID	            "ID [%.0f]"                                 (gRocketLaunch) {http="<[rocketlaunch:300000:JSONPATH($.launches[0].id)]"}
Number RocketLaunchTimeEpoch	    "Launch Time Epoch [%.0f]"      <flowpipe>  (gRocketLaunch) {http="<[rocketlaunch:300000:JSONPATH($.launches[0].netstamp)]"}

i’m getting this error:

I’ve triple-checked the JSONPATH and it is correct. Using also different JSONPATHs so I think I know what I’m doing.
Maybe something is wrong with the pipe | symbol which is in the .name ?

Any help is greatly appreciated!

Try this, and see what’s in it

String DiagnosticRawReturn	    "Raw data from LaunchLibrary [%s]"  {http="<[rocketlaunch:300000:default"}

This is flooding the logs with:

Oh, I thought default worked for inbound. We just want a no-op transform

String DiagnosticRawReturn “Raw data from LaunchLibrary [%s]” {http="<[rocketlaunch:300000:REGEX((.*))"}

My point is that I think you are getting a return, not an error, from the HTTP binding. Something is going wrong after the HTTP request has been sent.

Hmm…

I’ve tried other HTTP requests to that site with very specific content, but I always get Error code 1010. Unfortunately I do not know what this error means.

Maybe there is an issue with the website.

I can access is through Firefox just fine and see the JSON content.

8

Me neither. I’d be fairly confident it comes from the remote site.

Try as http instead of https ?

Try some other web service, to eliminate some firewall issue etc. at your end.

Also no luck with http.

Could it be connected to this:

I’m using a pihole since recently. So Not sure if that makes a difference. But I can still access that API with my regular browser from my PC (and they all go through the pi-hole).

Yep. They’re filtering out non-browser access based on the user-agent field or some related combination of headers.

11

Is there any way to circumvent this?

12

I don’t think http binding has a way to override the User-Agent http header.

Also, this feature recently was added to sendHttpGetRequest, but it won’t be available until 3.0.

sendHttpGetRequest(String url, Map<String, String> headers, int timeout)

The only way I can think to do this is using curl in a shell script. But, first you’d need to figure out which http header (or headers) they’re filtering on.

Others may better ideas.

There is a way to get it now for 2.5.x. An updated core jar is available in this post. It works for me for an added header. I don’t know if it can help the problem in this thread or not.

I believe it’s unrelated to the http-binding (v1 addon).

However, from the http binding doc, it seems possible to add http headers:
