Rest Error Response Body
1 year ago Hello everyone, I've been working on my API for weeks now and I'm still arguing error handling in restful web services myself about how to handle my errors in a good and maintainable way. At some point in the Incremental API course, @JeffreyWay shows us a fine way to handle errors api error message design with the ApiController. (ie: respondWithError($message)). Then later in the serie he shows us how to handle errors with the exceptions handler of Laravel which now is found in the app/Exceptions/Handler.php file (I'm using Laravel 5.0). So that means that our code to respond with errors is duplicated and that bugs me. How would you deal with this in an efficient

Obviously every application's data is different, so that much I'm not concerned with, but rather the "response boilerplate", if you will. An example of what I mean: Successful request: { "success": true, "payload": { /* Application-specific data would go here. */ } } Failed request: { "success": false, "payload": { /* Application-specific data would go here. */ }, "error": { "code": 123, "message": "An error occurred!" } } json http://stackoverflow.com/questions/12806386/standard-json-api-response-format request response share|improve this question edited May 25 at 19:09 Laurel 3,98481540 asked Oct 9 '12 at 18:43 drrcknlsn 11.5k74080 5 People probably have learnt from SOAP and won't build it again... –Denys Séguret Oct 9 '12 at 18:44 7 @dystroy: Care to explain your comment? –drrcknlsn Oct 9 '12 at 18:49 1 I was really interested by this question as I had to design a JSON API recently and found myself wondering if they were any standards defining a response format. Yours actually looks quite nice, and looks worth using if you don't find a standard. It's a shame that the answers provided don't actually address the question. –Alex Oct 11 '12 at 21:05 7 @Alex unfortunately, that's because no matter where you go, there is no standard. Not only within JSON itself, but in terms of how to use it for RESTful applications, or anything else of the sort. Everybody does it differently. You can feel free to follow best-practices (HTTP-responses, meaningful package-structure, an eye towards structuring your data for consumption by your system), but everybody who is a major distributor is doing at least one thing different than the others... There is no standard, and there won't likely be one, so build something solid, and build it to fit you. –Nor
responses with Spring’s RestTemplate. Judging by the Twitter activity, people found it useful, so this time around I’m going http://springinpractice.com/2013/10/09/generating-json-error-object-responses-with-spring-web-mvc to write about the other side of the equation, which is generating the JSON error objects using Spring Web MVC. Something like this: { "code": "InvalidRequest", "message": "Invalid doodad", http://www.baeldung.com/global-error-handler-in-a-spring-rest-api "fieldErrors": [ { "resource": "doodadResource", "field": "key", "code": "NotNull", "message": "may not be null" }, { "resource": "doodadResource", "field": "name", "code": "NotNull", "message": "may not be null" } ] error handling } There are various ways to do this, but Spring 3.2 introduces a pretty elegant approach via the @ControllerAdvice annotation. The basic concept here is that we can define AOP-like “advice” around Spring Web MVC controllers. This advice captures exceptions and then maps them to JSON objects, which the advice sends in the response body. Of course we rest error handling can also send the appropriate HTTP status code in the headers too. (You can find out more about @ControllerAdvice and @ExceptionHandler in the post Error Handling for REST with Spring 3 by Eugen Paraschiv.) Note that the error-triggering event doesn’t really have to be an exception per se. For example, we might want bean validation errors or authorization errors—neither of which manifests itself as an exception—to map to JSON error objects. The key is to have these triggers generate exceptions that we can capture using the @ControllerAdvice component. Let’s look at an example involving bean validation. Here we have a controller. If the incoming resource is invalid, we want to generate a JSON error object. So first we do this: package myapp.web.controller; ... various imports ... @Controller @RequestMapping("/doodads") public class DoodadController { @Inject private DoodadService doodadService; @RequestMapping( value = "/{id}", method = RequestMethod.PUT, consumes = MediaType.APPLICATION_JSON_VALUE) public void updateDoodad( @PathVariable Long id, @RequestBody @Valid DoodadResource doodad, BindingResult bindingResult) { if (bindingResult.hasErrors()) { throw new InvalidRequestException("Invalid doodad", bindingResult); } doodadService.updateDoodad(doodad); } } Note t

Custom Error Message Handling for REST API Last modified: July 20, 2016 exceptions, REST, Spring by baeldung If you're new here, join the next webinar: "Secure a Spring REST API with OAuth2 + JWT" . Thanks for visiting! The Master Class of "Learn Spring Security" is out: >> CHECK OUT THE COURSE 1. Overview In this tutorial - we'll discuss how to implement an global error handler for a Spring REST API. We will use the semantics of each exception to build out meaningful error messages for client, with the clear goal of giving that client all the info to easily diagnose the problem. 2. A Custom Error Message Let's start by implementing a simple structure for sending errors over the wire - the ApiError: public class ApiError { private HttpStatus status; private String message; private List
