SimpleRestRequest

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):

Name	Type	Mandatory	Default value
requestName	String	N	''
methodName	String	N	''

note

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:

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):

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.

note

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.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');
