TAKCAR

A quick example of importing the Traccar longitude and latitude coordinates into the FreeTakServer.

On page load the script automatically begins a loop getting the longitude, latitude of devices from Traccar and posting them to FTS.

The Test Service button just tests to see that you can see a result on FTS.

There is also a dedicated testing page which tests the endpoints to confirm that they are reachable.

STEPS

Once downloaded copy the folder takcar_scripts to your htdocs or equivalent folder.

Open the web page via http://localhost/takcar_scripts/.

1.

Make sure that Traccar and FreeTakServer are running.

Make sure that all your EUD's are connected to the FreeTakServer.

Make sure you have an Apache distribution I use the XAMPP system however any system that has PHP will suffice.

2.

Open the config.php file and replace the variables with your Traccar and FreeTakServer variables.

Both the Traccar and FreeTakServer softwares must be running.

If you are running the servers over the internet you will need to port forward the appropriate ports to allow the endpoint connections.

The current XMLHttpRequest(); should not show any general errors or CORS policy errors.

3.

Open the testing page and click on the Start Test button to test the endpoints.

4.

Once you have confirmed that the endpoints are communicating you can open index.php on your machine via localhost.

5.

Now that everything is up and running the Test Service button can be clicked to immediately test a postPresence position on FTS.

The loop will continue to run as long as the webpage is open.

getPositions Traccar endpoint example.

http://127.0.0.1:8082/api/positions?token=Your_Token_Here

postPresence FreeTakServer endpoint example.

http://127.0.0.1:19023/ManagePresence/postPresence

I also added the function of posting RAW COT data via TCP on port 8087 via a PHP socket.

</event>

Notes

The scripts assume 19023 is the FTS API port and that 8082 is the Traccar API port.

It is also assumed that the scripts are running on the same machine as FTS and Traccar.

As long as the page is open the loop will continue to run but will stop on close.
