How to post a new position from an api with osmand protocol

Hello,

I tried to post a new position with a new value in traccar from my api using osmand protocol but it return me error 405 and i don't know what i'm doing wrong.

const api_url = "http://srv/api/positions/";

const api_url_test = "http://srv:5055/?id=17362&lat={13.6666}&lon={80.23000}&timestamp={2016-01-27%2018:55:47}&hdop={3}&altitude={33}&speed={23}"

// Set the headers
const headers = {
  "Content-Type": "application/json",
  "Accept": "application/json",
  "Authorization": "Basic " + Buffer.from("username:password").toString('base64')
};

// Set the payload data
const payload_data = {
  "deviceId": 17362,
  "time": "2023-05-15T10:00:00.000Z",
  "latitude": 37.1234,
  "longitude": -122.5678
};

// Convert the payload data to a JSON string
const payload_json = JSON.stringify(payload_data);

// fetch(api_url_test)
// Send the POST request with the payload data
fetch(api_url, {
  method: 'POST',
  headers: headers,
  body: payload_json
})
.then(response => {
  // Check if the request was successful
  if (response.status === 200) {
    console.log("Position added successfully!");
  } else {
    console.log("Failed to add position. Error code:", response.status);
  }
})
.catch(error => {
  console.error('Error:', error);
});

Can someone tell me what i'm doing wrong and if im on a good way to post a new position value for my device n°17362 ?

Thank you.

Your code is not using OsmAnd. It seems like you're trying to post to an API endpoint that doesn't exist.

Oh ok.. Thank you for answering me, do you have an example of how I could make a post with the osmand protocol via my api?

Yeah, check the Traccar Client code.

Thank you i will look at it !

Hi All,
I searched on the forum, but did not find such a case. I have a problem with the OsmAnd protocol. My broker sends a message:

10:31:27.334	info	javascript.0 (69200) script.js.62a7_-_OK: curl http://11.10.12.16:5055/?id=62a7&lat=49.08796&lon=22.56570&timestamp=1684225914&altitude=68&speed=0

However, there is an answer in the server logs:

GET /?id=62a7 HTTP/1.1
Host: 11.10.12.16:5055
User-Agent: curl/7.81.0
Accept: /

The above messages come to me every 5 minutes (this is how the device is set).

And below you have logs that jumped me correctly only once today ...

It's some kind of black magic...
Will you help me understand and fix it? Please...

Clearly some issue with your broker, so I'm not sure how we can help.

Anton,
Why do you think with a broker? I sent you the data sent from the broker above. It looks like properly configured osmand code from the traccar website (https://www.traccar.org/osmand/)

Because it doesn't send the data?

Anton,

I don't know if you noticed in the first message, but I send using CURL, so the broker has nothing to do here. When I type a CURL with OsmAnd code on the command line, I get the correct answer. Also, a string of data, consistent with your example of the OsmAnd protocol, goes to Traccar. You have everything in my first post. Step by step - from sending CURL to Traccar logs. Strange.

One more thing, I used the second device - the same script. The device looks like this in the logs:

2023-04-28 10:42:38  INFO: [T4ee1951e] id: 60p8, time: 1970-01-01 01:00:00, lat: 0.00000, lon: 0.00000, course: 0.0

Although the broker sent the correct data...

Dear Sirs, Dear Anton,
I noticed that the problem still arises... I have done many tests of the broker and all the data comes out of it correctly. Below I send what I get from the broker in the Traccar logs:

POST /?id=62a7&lat=49.08796&lon=22.56570&timestamp=1687772082&altitude=0&speed=0&batt=58&hdop=9 HTTP/1.1

The problem is rather in Traccar, but I can not find where....

I ask you for help. I have no idea anymore.

Please.... Don't ignore my question, be gentlemen, Anna.

Thank You.

Are you sure you're using the latest version of Traccar?

I am using version 5.4 and I did an update to 5.8 -

I noticed an error:

MessageBodyReader not found for media type=text/plain;charset=utf-8, type=interface javax.json.JsonObject, genericType=interface javax.json.JsonObject. - MessageBodyProviderNotFoundException (... < NotificatorTraccar:106 < NotificationManager:110 < ... < *:107 < ... < *:106 < *:148 < ConnectionManager:247 < ...)

and in my broker server -
I noticed an error: socket hang up

Seems like an issue with push notifications.

I agree. Do you have any idea why? Any suggestion?
