This server class allows to operate with the REST API methods and parameters.

SimpleRestRequest(requestName, methodName)

This method is intended to create an object used in the REST requests. When using the method, an object is created with the sws prefix (see the code example below for clarification).

Parameter(s):

Name	Type	Mandatory	Default Value
requestName	String	N	N
methodName	String	N	N

Info

Provide values for parameters as shown below:

Parameter	Value
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:

Type	Description
SimpleRestRequest object	This method returns a SimpleRestRequest object initiated by the query transmitted; otherwise, it returns an empty SimpleRestRequest object.

Example:

Code Block

language	js
theme	Eclipse
title	SimpleRestRequestApi
linenumbers	true

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

The method prepares a file in binary format for sending it in a request.

Parameter(s):

Name	Type	Mandatory	Default Value	Description
content	String	Y	N	The base64 encoded binary file data.
paramName	String	Y	N	The name of the parameter in the POST request that will transmit the binary data.
fileName	String	Y	N	The file name.

Info
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].

Return:
