RESTAPIResponseStream - Scoped, Global

The RESTAPIResponseStream API provides methods that allow you to write directly to the scripted REST API response stream.

Use RESTAPIResponseStream methods to build web service APIs in the Scripted REST API feature.

This API runs in the sn_ws namespace.

Note: You cannot instantiate objects of this type. Objects of this type are created automatically and are accessible only in scripted REST API resource scripts.

RESTAPIResponseStream - writeStream(Object stream)

Write an input stream to the response stream.

You must set the content type and status code before calling the writeStream() method or the response will fail. You cannot modify these values after calling the writeStream() method.

Note:

It is the responsibility of the script author to obtain the stream from a third-party service.

The following example is for scoped applications:

(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {

    response.setContentType('application/json');
    response.setStatus(200);

    var gsa = new GlideSysAttachment();
    var attachmentStream = new gsa.getContentStream(<sys_id of attachment>); 
    var writer = response.getStreamWriter();
    writer.writeStream(attachmentStream);

})(request, response);

The following example is for global applications:

(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {

    response.setContentType('application/json');
    response.setStatus(200);

    var attachmentStream = new GlideSysAttachmentInputStream(<sys_id of attachment>);
    var writer = response.getStreamWriter();
    writer.writeStream(attachmentStream);

})(request, response);

RESTAPIResponseStream - writeString(String data)

Write string data to the response stream.

You must set the content type and status code before calling the writeString() method or the response will fail. You cannot modify these values after calling the writeString() method.

response.setContentType('application/json');
response.setStatus(200);
var writer = response.getStreamWriter();
var body ={
  name:user1,
  id: 1234,
  roles: [
    {
      name: admin
    },
    {
      name: itil
    }
  ]
}
writer.writeString("{'name':'user','id':'1234'}");
writer.writeString(JSON.stringify(body));
