Error :4 on Import WLP with php wialon master

Тема: Error :4 on Import WLP with php wialon master

I started to developed my own app with PHP Wialon master, I’m trying to import a WLP to the platform but I’m getting Error:4 for every time I trying to execute.
I generate the WLP automatically and I get a file with all the configuration, I leave a part below (It’s well-formed because I prove to import directly to the platform and ain’t getting any problem).

К сожалению, у вас не достаточно прав для просмотра данного текста


However when I try to import through php code I getting error:4, I know that my code is wrong but maybe you can help to see how to do it. I leave it below.

I will really appreciate all your opinion and tips.
Thanks in advance

Error :4 on Import WLP with php wialon master

Re: Error :4 on Import WLP with php wialon master

Hi monitoreo2

Here's simple sample how to upload file to wialon.
Dont forget to change TOKEN and UNIT_ID to yours. Also create msgs.wln file
Hope this helps:)

<?
    $url = 'https://hst-api.wialon.com';
    $token = TOKEN;
    $unitId = UNIT_ID;
    $filename = 'msgs.wln';

    // Login request
    $params = array('token' => $token);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url.'/wialon/ajax.html?svc=token/login');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'params='.json_encode($params));
    $out = curl_exec($ch);
    curl_close($ch);
    $out = json_decode($out, true);

    // get sid from login response
    $sid = $out['eid'];

    // import_messages request (upload file)
    $params = array(
        'sid' => $sid,
        'itemId' => $unitId
    );
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url.'/wialon/ajax.html?svc=exchange/import_messages&sid='.$sid);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, array(
        'file' => '@'.realpath($filename),
        'params' => json_encode($params)
    ));
    $out = curl_exec($ch);
    curl_close($ch);

    echo $out;

Re: Error :4 on Import WLP with php wialon master

Hi! Thanks for your help

I use your code and continued getting the error 4, I modify some lines and try of different ways but this error continued but with different reasons some are "WRONG_PARAMS" or "VALIDATION_PARAMS_ERROR: ItemId:long".

<?php 
    $url = 'https://hst-api.wialon.com';
    $token =TOKEN;
    $unitId = 16374707;
    $filename = 'filename.wln';

    // Login request
    $params = array('token' => $token);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); //Added this line because I'm using windows operating system and without this doesn´t work
    curl_setopt($ch, CURLOPT_URL, $url.'/wialon/ajax.html?svc=token/login');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'params='.json_encode($params));
    $out = curl_exec($ch);
    curl_close($ch);
    $result = json_decode($out, true);
    // get sid from login response
    $sid = $result['eid'];
   // import_messages request (upload file)

    $params = array(
     
        'itemId' => $unitId
    );

    $params2 = array(
        'file' => '@'.realpath($filename),
        'params' => json_encode($params)
    );
    $ch = curl_init();
  
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);                
    curl_setopt($ch, CURLOPT_URL, $url.'/wialon/ajax.html?svc=exchange/import_messages&sid='.$sid);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'params='.json_encode($params));
    $out = curl_exec($ch);
    curl_close($ch);



   /* $args = array(
        //'sid' => $sid,*/        

    /*$params = array(
            'svc' => "exchange/import_messages",
            'sid' => $sid,
            'params' =>array('itemId' => $unitId),
            'file' => '@'.$filename
        );
//$params['messages_filter_import_file'] = '@'.$filename;

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_URL, $url.'/wialon/ajax.html?'.json_encode($params));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    /*curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($params));
    $out = curl_exec($ch);
    curl_close($ch);*/


    echo $out;
?>

And I got a question about it, This works with WLP files or only with WLN files? like the option https://sdk.wialon.com/wiki/en/kit/remo … mport_json

I will really appreciate if you continued helping me smile

Error :4 on Import WLP with php wialon master

Re: Error :4 on Import WLP with php wialon master

The code above shows how to upload file to Wialon using Remote API. Extension and svc doesn't matter.

Also note that exchange/import_json request doen't actually import anything. Just parse JSON and return parsed result back in *avl_evts*

Here's working sample with .wlp (replace TOKEN and place unit.wlp in folder)

<?
    $url = 'https://hst-api.wialon.com';
    $token = 'TOKEN';
    $filename = 'unit.wlp';

    // Login request
    $params = array('token' => $token);
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url.'/wialon/ajax.html?svc=token/login');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'params='.json_encode($params));
    $out = curl_exec($ch);
    curl_close($ch);
    $out = json_decode($out, true);

    // get sid from login response
    $sid = $out['eid'];

    // import_messages request (upload file)
    $params = array(
        'sid' => $sid,
        'eventHash' => 'any_random_string_you_like'
    );
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url.'/wialon/ajax.html?svc=exchange/import_json&sid='.$sid);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, array(
        'file' => '@'.realpath($filename),
        'params' => json_encode($params)
    ));
    $out = curl_exec($ch);
    curl_close($ch);

    echo "exchange/import_json: $out<br/>";

    // wait while file parsing
    sleep(3);

    // get events
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url.'/avl_evts?sid='.$sid);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch, CURLOPT_POST, true);
    $out = curl_exec($ch);
    curl_close($ch);

    // In response you'll see event with hash 'any_random_string_you_like'
    // This is result of parsing uploaded file
    echo "avl_evts: $out<br/>";

I try with both (exchange/import_json,exchange/import_messages ) but the error continued, I modify some lines and try of  differents ways but always get error:4

I leave my code below.

<?php 
    $url = 'https://hst-api.wialon.com';

    $params2 = array(

    );
    $ch = curl_init();
  
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'params='.json_encode($params));
    $out = curl_exec($ch);
    curl_close($ch);

//The code below is another way that I try but get the same error

   /* $args = array(
        //'sid' => $sid,*/        

    $params = array(
            'svc' => "exchange/import_messages",
            'sid' => $sid,
            'params' =>array('itemId' => $unitId),

        );
//$params['messages_filter_import_file'] = '@'.$filename;

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);

    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($params));
    $out = curl_exec($ch);
    curl_close($ch);


    echo $out;

I don´t know what is wrong with that , this should work but it isn´t.

Please check your code

Error :4 on Import WLP with php wialon master

Re: Error :4 on Import WLP with php wialon master

This is exactly the code that I´m using but I continued getting error:4, as you can see it´s the same that you passed me the first time, only declare the params outside of CURLOPT_POSTFIELDS add the avl_evts to see what I got but the result its actually nothing.

<?php 
    $url = 'https://hst-api.wialon.com';
    $token = 'token';
    $unitId = 1111111; //I try with a string too
    $filename = 'prueba.wlp'; //This file is in the same place that the code file

    // Login request
    $params = array('token' => $token);
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, $url.'/wialon/ajax.html?svc=token/login');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, 'params='.json_encode($params));
    $out = curl_exec($ch);
    curl_close($ch);
    $result = json_decode($out, true);
    // get sid from login response
    $sid = $result['eid'];
   // import_messages request (upload file)
    $params = array(
        'sid' => $sid,
        'itemId' => $unitId
    );

    $params2 = array(
        'file' => '@'.realpath($filename),
        'params' => json_encode($params)
    );

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url.'/wialon/ajax.html?svc=exchange/import_messages&sid='.$sid);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $params2);
    $out = curl_exec($ch);
    curl_close($ch);
    echo $out;

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_URL, $url.'/avl_evts?sid='.$sid);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,true);
    curl_setopt($ch, CURLOPT_POST, true);
    $out = curl_exec($ch);
    curl_close($ch);
    echo "<br><br>avl_evts: $out<br/>";
?>

In last sample you send file with exchange/import_messages request, so i believe prueba.wlp should be .wln or .wlb file with messages inside. Please try your code with messages.wln file from attachment

I continued getting the same error even with the file that you attach in the previous response, I try it local and in a server with different ways and files but the result is always the same.

How could be this possible?

Error :4 on Import WLP with php wialon master

Re: Error :4 on Import WLP with php wialon master

exchange/import_json method just parse file, not create any Items in Wialon.

If you have wlp file and want to create unit using it try these steps
- parse file with exchange/import_json (or you can do it on PHP side)
- get all needed data from parsed data (e.g. hw type, sensors or whatever you have in wlp file)
- using data from previous step create unit with core/create_unit request
- update other params with unit/unit requests
