`OctoPrintClient.util`¶

Note

All methods here require that the used API token or the existing browser session has admin rights.

OctoPrintClient.util.test(command, parameters, opts)¶

Execute a test command.

See below for the more specialized versions of this.

Arguments

command (string) – The command to execute (currently either path or url)
parameters (object) – The parameters for the command
opts (object) – Additional options for the request

Returns Promise

A jQuery Promise for the request’s response

OctoPrintClient.util.testPath(path, additional, opts)¶

Test the provided path for existence. More test criteria supported by the path test command can be provided via the additional object.

Example 1

Test if /some/path/to/a/file exists.

OctoPrint.util.testPath("/som/path/to/a/file")
    .done(function(response) {
        if (response.result) {
            // check passed
        } else {
            // check failed
        }
    });

Example 2

Test if /some/path/to/a/file exists, is a file and OctoPrint has read and executable rights on it.

OctoPrint.util.testPath("/som/path/to/a/file", {"check_type": "file", "check_access": ["r", "x"]})
    .done(function(response) {
        if (response.result) {
            // check passed
        } else {
            // check failed
        }
    });

Arguments

path (string) – Path to test
additional (object) – Additional parameters for the test command
opts (object) – Additional options for the request

Returns Promise

A jQuery Promise for the request’s response

OctoPrintClient.util.testExecutable(path, opts)¶

Shortcut to test if a provided path exists and is executable by OctoPrint.

Example

Test if /some/path/to/a/file exists and can be executed by OctoPrint.

OctoPrint.util.testExecutable("/some/path/to/a/file")
    .done(function(response) {
        if (response.result) {
            // check passed
        } else {
            // check failed
        }
    });

This is equivalent to calling OctoPrint.util.testPath() like this:

OctoPrint.util.testPath("/some/path/to/a/file", {"access": "x"})
    .done(function(response) {
        if (response.result) {
            // check passed
        } else {
            // check failed
        }
    });

Arguments

path (string) – Path to test
opts (object) – Additional options for the request

Returns Promise

A jQuery Promise for the request’s response

OctoPrintClient.util.testUrl(url, additional, opts)¶

Test if a URL can be accessed. More test criteria supported by the URL test command can be provided via the additional object.

Example 1

Test if http://octopi.local/online.gif can be accessed and returns a non-error status code within the default timeout.

OctoPrint.util.testUrl("http://octopi.local/online.gif")
    .done(function(response) {
        if (response.result) {
            // check passed
        } else {
            // check failed
        }
    });

Example 2

Test if http://octopi.local/webcam/?action=snapshot can be accessed and returns a non-error status code. Return the raw response data and headers from the check as well.

OctoPrint.util.testUrl("http://octopi.local/webcam/?action=snapshot", {"response": "bytes", "method": "GET"})
    .done(function(response) {
        if (response.result) {
            // check passed
            var content = response.response.content;
            var mimeType = "image/jpeg";

            var headers = response.response.headers;
            if (headers && headers["content-type"]) {
                mimeType = headers["content-type"].split(";")[0];
            }

            var image = $("#someimage");
            image.src = "data:" + mimeType + ";base64," + content;
        } else {
            // check failed
        }
    });

Example 3

    .done(function(response) {
        if (response.result) {

            // check failed
        }
    });

Arguments

url (string) – URL to test
additional (object) – Additional parameters for the test command
opts (object) – Additional options for the request

Test if a server is reachable. More options supported by the server test command can be provided via the additional object.

Example 1

Test if 8.8.8.8 is reachable on port 53 within the default timeout.

OctoPrint.util.testServer("8.8.8.8", 53)
    .done(function(response) {
        if (response.result) {
            // check passed

            // check passed
        } else {
            // check failed
        }
    });

Arguments

url (string) – Host to test
port (int) – Port to test
