This server class provides methods to work with the REST API methods and parameters.

SimpleRestRequest object


To create a SimpleRestRequest object, use the sws.restRequestV1 method as described below.

Parameter(s):

NameTypeMandatoryDefault value
requestNameStringN''
methodNameStringN''


Provide values for parameters as shown below:

ParameterValue
requestName Specify the value of the Name field taken from the record in the REST Requests (sys_rest_requests) table.
methodName Specify the value of the Name field taken from the record in the REST Request Methods (sys_rest_request_method) table related with this request.

Return:

TypeDescription
SimpleRestRequest objectThis method returns a SimpleRestRequest object initiated by the query transmitted; otherwise, it returns an empty SimpleRestRequest object.

Example:

Creating a SimpleRestRequest object
/* Create a 'Telegram' request in the REST Requests (sys_rest_requests) table
and the 'Send Message' method in the REST Request Methods (sys_rest_request_method) table related with the 'Telegram' request.
Also create the 'chat_id' and 'text' Rest Request Method Param (sys_rest_request_method_param) related with the 'Send Message' method
*/

const request = sws.restRequestV1('Telegram', 'Send Message');
request.setStringParameter('chat_id', '123456789');
request.setStringParameter('text', 'telegram');
const response = request.execute();

// OR

const request = sws.restRequestV1();
request.setRequestUrl('https://api.telegram.org/bot1860462740:AAHyP6BMH2Mh-cXezrTVu2sJUoNYvimMRMQ/sendMessage');
request.setQueryParameter('chat_id', '123456789');
request.setQueryParameter('text', 'telegram');
const response = request.execute();

addFileContent(content, paramName, fileName)


Use the method to prepare a file in binary format for sending it in a request.

Parameter(s):

NameTypeMandatoryDefault valueDescription
contentStringYNThe base64 encoded binary file data.

It is possible to add several files to one request. In this case, the name of the POST request parameter should look like an array of elements. For example, if there is one file, the parameter can be called files. If there are two files, they should be called files[1] and files[2].

request.setRequestUrl('https://instance.example2.com/v1/attachments/upload/task/165469349718887155'); // the URL where to upload files
request.addFileContent(downloadResponse.getContentBase64(), 'files[1]', 'file.png');
request.addFileContent(downloadResponse.getContentBase64(), 'files[2]', 'file2.png');
const uploadResponse = request.execute();


Adding one file
const request = sws.restRequestV1(); 
request.setRequestUrl('https://instance.example1.com/some/service'); //the URL from which the file is downloaded
const downloadResponse = request.execute();

request.setRequestUrl('https://instance.example2.com/v1/attachments/upload/task/165469349718887155'); // the URL where to upload files

request.setRequestMethod('POST');
request.setBasicAuth('admin', 'password');
