Query parameters GET example

This example demonstrates how to get query parameter values from a request.

/**
 * GET - Sample Request API - Query Params
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    var uri = request.uri;
    var url = request.url;
    var queryParams = request.queryParams;
    var customHeader = request.getHeader('X-Custom');

    return {
        "uri": uri,
        "url": url,
        "queryParams": queryParams,
        "customHeader": customHeader
    };

})(request, response);

Path parameters GET example

This example demonstrates how to get path parameter values from a request.

/**
 * GET - Sample Request API - Path Params
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    var uri = request.uri;
    var url = request.url;
    var path = request.pathParams;

    return {
        "uri": uri,
        "url": url,
        "path_params": path,
        "path.id": path.id
    };
})(request, response);

Script include GET example

This example demonstrates how to use a script include to provide a response. By using a script include you can reuse common code and maintain readability in the REST service scripts.

/**
 * GET - Sample Request API - Script Include
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    var responseObj = global.SampleDataUtil.getSampleJSON();
    return responseObj;
})(request, response);

String POST example

This example demonstrates how to parse a POST message with a string body and send a response based on the request.

/**
 *  POST - Sample Request API - dataString
 *  sample usage:
 *  var requestBody = request.body;
 *  var requestString = requestBody.dataString;
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    var requestBody = request.body;
    var requestString = requestBody.dataString;
    return {"requestString": requestString};
})(request, response);

Binary POST example

This example demonstrates how to parse a POST message with a binary body and send a response based on the request.

/**
 * POST - Sample Request API - Body
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    var body = request.body.data;
    //do any additional processing on the request body, such as inserting a new record.
    return {
        "body.id": body.id
    };
})(request, response);

Not acceptable error example

This example demonstrates how to respond with a not acceptable error. Use this error type when the request Accept header value is not supported by the web service.

/**
 * Sample Not Acceptable Error Sample
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    response.setError(new sn_ws_err.NotAcceptableError('sample error message'));
})(request, response);

Bad request error example

This example demonstrates how to respond with a bad request error. Use this error type to indicate a mistake in the request syntax.

/**
 * Bad Request Error Sample
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    response.setError(new sn_ws_err.BadRequestError('sample error message'));
})(request, response);

Conflict error example

This example demonstrates how to respond with a conflict error. Use this error type in the event of multiple conflicting requests, such as multiple updates to the same record.

/**
 * Error Response: Conflict Error Sample
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    response.setError(new sn_ws_err.ConflictError('sample error message'));
})(request, response);

Not found error example

This example demonstrates how to respond with a not found error. Use this error type if the requested resource does not exist or is unavailable.

/**
 * Error Response: Not Found Error Sample
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    response.setError(new sn_ws_err.NotFoundError('sample error message'));
})(request, response);

Unsupported media type error example

This example demonstrates how to respond with an unsupported media type error. Use this error type to indicate that the Content-Type of the request is unsupported.

/**
 * Error Response: Unsupported Media Type Error Sample
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    response.setError(new sn_ws_err.UnsupportedMediaTypeError('sample error message'));
})(request, response);

Service error example

This example demonstrates how to respond with a generic service error. The ServiceError object allows you to define the status code, message, and error detail. Use a ServiceError if the predefined error types do not meet your needs.

/**
 * Error Response: Custom Error Sample
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
    var myError = new sn_ws_err.ServiceError();
    myError.setStatus(418);
    myError.setMessage("I am a Teapot");
    myError.setDetail("Here are the details about this error");
    response.setError(myError);
})(request, response);

Function parentheses error example

This example demonstrates that if a function is not wrapped in parentheses, it results in a error. Include parentheses with all functions.

(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
	gs.info("message: {0}", request.body.data.message);
})(request, response);

function test() {
	gs.info("test");
}(request, response);

Serialization error example

This example demonstrates that if the request is set as a body to the response, it can result in a serialization error.

setBody_request:
    response.setBody(request);

This example demonstrates that if the response is set as a body to the response, it can result in a serialization error.

setBody_response:
    response.setBody(response);

This example demonstrates that if the request is returned, it can result in a serialization error.

return_request:
    return request;

This example demonstrates that if the response is returned, it can result in a serialization error.

return_response:
    return response;

Scripted REST resource script example

/**
 * POST - Sample Request API - Body
 */
(function process(/*RESTAPIRequest*/ request, /*RESTAPIResponse*/ response) {
var body = request.body.data,
id0,name0,id1,name1;
name0 = body[0].name; // 'user0'
id0 = body[0].id; // '1234'
name1 = body[1].name; // 'user1'
id1 = body[1].id; // '5678'

return {
"id": id0,
"name": name0,
"id1": id1,
"name1": name1
};
})(request, response);
