Error Handling In Rest Api
REST, HTTP, XML and URIs provide all the infrastructure for building error handling in rest services robust web services, and most developers can therefore safely skip over the pain of learning SOAP error handling in rest web services and WSDL. If you are new to REST, check out Paul Prescod's excellent REST articles on xml.com. A major element of web services is planning for when
Rest Api Return Error
things go wrong, and propagating error messages back to client applications. However, unlike SOAP, REST-based web services do not have a well-defined convention for returning error messages. In fact, after surveying a number of REST-based web services in the wild, there appear to be four different alternatives for handling errors. Below, I outline the
Rest Error Message Best Practice
four alternatives, and then provide my opinion on which option or combination of options is best. Option 1: Stick to HTTP Error Codes In this scenario, the web service propagates error messages via standard HTTP Error Codes. For example, assume we have the following URL: http://www.example.com/xml/book?id=1234&dev_token=ABCD1234 This service expects a single parameter: id indicating a book ID. The service extracts the id parameter, does a database look-up and returns an XML representation of the specified book. If the URL specifies an invalid or obsolete id parameter, the service returns an HTTP 404 Not Found Error Code. Option 2: Return an Empty Set In this scenario, the web service always returns back an XML document which can have 0 or more subelements. If some error occurs, an XML document with zero elements is returned. The O'Reilly Meerkat news service currently uses this approach. For example, the following URL connects to Meerkat and requests all Linux related articles from the past t

In Part II, we briefly mentioned what to do in case of errors that might arise http://blog.cloud-elements.com/error-handling-restful-api-design-part-iii from your APIs, but in this post we take a deeper dive into what to do when it all goes terribly wrong. If you want to brush up on the topics we covered in the previous posts, check them out here: RESTful API Design Part I: POST /EFF/YOU/THIS/IS/THE/RIGHT/URL RESTful API Design Part II: 418: I'm a Teapot, and Other Bad API Responses There are many ways to communicate the success or failure of an API call, but these are some of the techniques we have found to be the most intuitive here at Cloud Elements, where we integrate to a LOT of APIs. Since this is a series on RESTful APIs, we are already assuming that our API calls are being made over HTTP(S). The great thing about using HTTP for interacting with APIs is that it has built-in status codes that can give your users some good information about the success or failure of your calls. Why not make the most of them? But, but… Why? In our experience, great error messages are incredibly helpful when integrating with an API. Good error codes and messages should help guide developers toward the correct way to integrate with an endpoint. Some folks read through pages and pages of documentation before starting, but others are more comfortable jumping in feet first and seeing what works. With great error handling, the latter group will be able to figure out exactly what they

Unfortunately things do go wrong from time to time, and when it does we should be prepared to some extent at least… This is error handling in especially the case when writing REST APIs, because clients only get a black box with specification, having no clue what to do when the expected answer doesn't come back, unless we do something about it… Bottom line: error handling is essential when designing REST APIs. In this post I will present how I've designed and implemented the error handling of a REST API with the help Jersey framework.

Source Code 6.2. Codingpedia 6.3. Web 1. Design There are usually two causes for error occurence: either something failed on the server or the client of the API sent an invalid request. In both cases I've decided to send back a response with some metadata that should be useful for client, and potentially the developers of the clie
(part 1) by Les Hazlewood | March 18, 2012 |JavaREST APIIf you’re already using Spring to build your application, and you need to serve a ReST API, Spring MVC can be a good choice to write your REST endpoints.However, representing errors or problems cleanly in a RESTful way may not be immediately obvious since Spring MVC is so often referenced for building user interfaces. Because there is no direct UI concept in REST APIs, how then do you use Spring MVC to represent errors or problems in a clean and intuitive way?This article is Part 1 of a 2 part series. In this article, we’ll cover RESTful error reporting best practice conventions. Part 2 will show how to implement them with Spring MVC in a complete example web application.RESTful Error DesignIf an error occurs, RESTful practices expect that we set an HTTP status code in the response to generally classify why the request failed. It is considered best practice by most REST API designers to re-use the status codes in the HTTP specification whenever possible, since so many existing HTTP clients understand most of these error conditions already and re-use encourages consistent behavior, which is always good for development.However, there are only 24 commonly referenced HTTP status codes that are used for representing errors; there are 18 4xx codes representing client errors and 6 5xx codes representing server errors (there are other codes defined in specifications like WebDav, but they are not ubiquitous). A problem here is that these 24 are really general purpose codes - they likely don’t describe everything there is to know about a particular problem.To best help your REST API customers, you ideally want to give them as much information as possible to help them diagnose and hopefully fix the problem. The name of the game is simplicity: the easier it is for them to use your REST API, the more likely it is they will adopt your service.REST Error RepresentationBecause the status code is probably not enough, what else then can we provide to assist our end users whenever they encounter errors? An obvious item is human readable error message, to be easily read by developers. But there is even more informa
