allow commands to users only read

[gechdell]

that such, I have a small problem that I do not know how to solve it, I am modifying the frontend so that in the read-only view, users can send commands to the devices, I already have in the read-only view the command button, click opens the dialog window and the commands are visible, but when I try to send one, it gives me the following error

HTTP ERROR 401

Problem accessing /traccar/rest/sendCommand. Reason:

Unauthorized

I was lost to solve it, could help me solve it

sorry my english but I'm using google translator

You need to update the DataServiceImpl as well because currently it disallows sending of commands by read-only users. You need to change annotations on sendCommand method.

Thanks for your answer, but already trying to modify the parameters in the DataServiceImpl but I still get the same error 401, in this section

`public String sendCommand(Command command) throws AccessDeniedException { Device device = getSessionEntityManager().find(Device.class, command.getDeviceId()); if (!getSessionUser().hasAccessTo(device)) { throw new AccessDeniedException(); }

    //if (applicationSettings.get().isAllowCommandsOnlyForAdmins() && !getSessionUser().getAdmin()) {
    if (applicationSettings.get().isAllowCommandsOnlyForAdmins()) {
        throw new AccessDeniedException();
                }`

I am lost, you could orientate me more, since I have been several days and I do not find the solution

[vitalidze]

You need to remove @RequireWrite annotation from method in DataServiceImpl class. All methods annotated in same way will not be allowed to execute by read-only user.

[gechdell]

perfect thank you very much for your help simply commenting the @RequireWrite line is solved and already read users can send commands.

I would also like to add to the mobiles view a command send button, as well as sending it by email or sms, I plan to send the data to the API, any suggestions?

You should be able to use sendCommand method via RESTful API. You can find additional information here: http://traccar.litvak.su/features/rest-api.html

hello vitalidze, I appreciate your great help, I was trying to use the RESTful API as you suggested, but I can not get the expected results, if I try on the page for mobile write this code

` $$.ajax({

                            url: '../traccar/rest/sendCommand',
                            method: 'POST',
                            dataType: 'json',
                            data:JSON.stringify([{"deviceId": deviceId, "type": "engineStop"}]),
                            processData: false,
                            start: function(xhr) {
                                if (options.showIndicator != undefined && options.showIndicator) {
                                    myApp.showIndicator();
                                }
                            },
                            success: options.success,
                            complete: function(xhr) {
                                if (options.showIndicator != undefined && options.showIndicator) {
                                    myApp.hideIndicator();
                                }
                                if (xhr.status != 200 && options.error != undefined) {
                                    options.error(xhr);
                                    options.error = undefined;
                                }
                            },
                            error: function(xhr) {
                                options.error(xhr);
                                options.error = undefined;
                            }
                        })

`

but does not do anything, try to do it as a test by means of curl with the following

curl -v --cookie "JSESSIONID=134u24dd0vagq1h4s2959ehnu2" POST --data "[{\"deviceId\":5,\"type\":\"engineStop\"}]" localhost:8082/traccar/rest/sendCommand

and the console responds

upload completely sent off: 36 out of 36 bytes < HTTP/1.1 200 OK < Date: Wed, 13 Sep 2017 20:42:15 GMT < Content-Type: application/json; charset=UTF-8 < Content-Length: 4 < Server: Jetty(9.2.22.v20170606)

but the device does nothing, enter the server log and I see this error

[vitalidze]

I think your request is not properly formatted. You need to read documentation carefully.
