Rest api boolean endpoint

An API for a website is code that allows two software programs to communicate with each other. The API spells out the proper way for a developer to write a program requesting services from an operating system or other application. The REST used by browsers can be thought of as the language of the internet.

With cloud use on the riseAPIs are being used by cloud consumers to expose and organize access to web services. Each module addresses a particular underlying part of the transaction. This modularity provides developers with a lot of flexibility, but it can be challenging for developers to design their REST API from scratch.

With REST, networked components are a resource the user requests access to -- a black box whose implementation details are unclear. All calls are stateless; nothing can be retained by the RESTful service between executions. Because the calls are statelessREST is useful in cloud applications. Stateless components can be freely redeployed if something fails, and they can scale to accommodate load changes. This is because any request can be directed to any instance of a component; there can be nothing saved that has to be remembered by the next transaction.

Roy Fielding in his doctorate dissertation. RESTful web services are stateless. REST services are useful for restricted profile devices, such as mobile, and are easy to integrate with existing websites. SOAP requires less plumbing code -- meaning low-level, infrastructural code that connects main code modules together -- than REST services design. The Web Services Description Language describes a common set of rules to define the messages, bindings, operations and location of the service.

SOAP web services are useful for asynchronous processing and invocation. InRoy Fielding and a group of developers decided to create a standard so that any server could talk to any other server. These universal rules make it easier for developers to integrate software. This caught the attention of another ecommerce giant, and Amazon announced its API in Please check the box if you want to proceed. Automated testing can add speed and completeness to the software development process, but be sure you've considered the tradeoffs Many unlucky online shoppers have fallen prey to 'porch pirates' who steal packages from outside their homes.

Endpoints are functions available through the API. This can be things like retrieving the API index, updating a post, or deleting a comment. Endpoints perform a specific function, taking some number of parameters and return data to the client. A route can have multiple endpoints associated with it, and which is used depends on the HTTP verb.

The second argument passed in is the resource path, or resource base. The third argument is an array of options. We specify what methods the endpoint can use and what callback should happen when the endpoint is matched more things can be done but these are the fundamentals.

The third argument also allows us to provide a permissions callback, which can restrict access for the endpoint to only certain users. The third argument also offers a way to register arguments for the endpoint so that requests can modify the response of our endpoint.

We will get into those concepts in the endpoints section of this guide. All routes should be built onto this route, the wp-json portion can be changed, but in general, it is advised to keep it the same.

We want to make sure that our routes are unique. However, this is not a good practice as we would end up polluting potential routes for the API. What if another plugin we wanted to register a books route as well? We would be in big trouble in that case, as the two routes would conflict with each other and only one could be used.

The override parameter does not really solve our problem either, as both routes could override or we would want to use both routes for different things. This is where using namespaces for our routes comes in. It is extremely important to add namespaces to your routes. There are some key things to take notice of in the core endpoint namespace.I must stress that some of the statements I'll present are strictly personalconclusions I reached through my limited experience in this area.

This way, responses to simple requests like setting a value to true or false can be defined just by status codes, no additional data involved. Check out the status codes here. Enforcing a clear naming convention is critical, and this one obeys JavaScript conventions and it is familiar in Java and Objective-C. So make something like this:.

This one is quite trivial, but is has a few nuances. Non existing numbers, strings, and booleans are usually represented as null. But string fields without value should also be represented as nullnot "".

Note : Empty arrays shall not be null. If a field is some kind of list and it is represented by an array, an array shall be returned, even if empty. Use what you have: true and false. This is redundant. Also, this maintains a cleaner response, removing superfluous fields and unnecessary encapsulations.

You should always include an array of errors in the response.

Even if no errors occurred, you should include an array of errors. A successful response is an absence of errors, thus an empty array. When handling the response, you will check first for the presence of errors, and only then you proceed. You should paginate your responses Some requests can be really long and heavy, like listings.

So it is wise to follow a strategy of defining the start and end of a request. You should provide partial responses What if you just want to request updates of a particular field of a complex entity? There should be no need to request all of the info So adding a field specifier is good practice.

Something like this will receive only the requested field:? I think you meant to say camelCase notation not cameCase when describing naming response fields. I like the tip though :.

Not sure what your use case might be, but returning an array of errors with every response makes little sense to me, and is definitely not RESTful as errors are not part of the resource representation.

Some great tips there. Only thing I would as is don't do pagination with limit and offset. Instead use a 'next' and 'previous' and use and offset. Either time off or ID offset.

REST Resource Naming Guide

See some of the conversation here it explains better then me. With constantly updating data limit and offset will mean missed data when moving from page to page. I'll definitely look into that, and update this protip. However, I've had some cases where that approach is not enough. When you want a more descriptive scenario about what's wrong in the server-side, experience showed me this to be a good approach.By using our site, you acknowledge that you have read and understand our Cookie PolicyPrivacy Policyand our Terms of Service.

Stack Overflow for Teams is a private, secure spot for you and your coworkers to find and share information. Resource has a current configuration state and a default configuration state, and both of these configuration states can be represented by JSON.

The true and false literals are just fine to represent boolean values. In a few situations, however, you may want to avoid boolean values because they cannot be expanded. You may want to consider enumerations instead. It may be a poor comparison but it might help you to get the main idea of this approach: have a look at CSS properties such as overflow or visibility.

They allow expandable values instead of only true or false. So new values can be easily added without changing the property names. So, for the situation described in your question, to retrieve the default state of a resource, I would support a query parameter such as statusthat could have values such as default and current.

If no query parameter is provided, you could that the client wants the current state of the resource. If you need to restore the resource state to its default state, consider using PUTsending the new representation of the resource in the request payload. Something like:. Learn more.

I am thinking that if reset is included in the query and is set to any value other than false case insensitive or 0then reset will be interpreted as TRUE. Seem reasonable?

Thanks for your response. Most sane users, I would assume, expect the variables of a boolean -type parameter to be boolean values, e.

And even if someone requests it, you should instead take the stance to have the user conform to a proper boolean-pattern.

Things like this should be standardized. Well, we should cater to sane users! I was originally basing my implementation on how HTML attributes such as selected need any value to be considered true.

Mach-II 1. The endpoint does not participate in the typical Mach-II event lifecycle, so it even lighter and faster than normal. Anyone that has created a Mach-II Listener, Filter, or Plugin will be familiar with this concept, but others -- just hang in there. Simply create a CFC with a declaration like this:. Here's an example method declaration:.

There are many things to note here. First, notice the two attributes prefixed with the rest: namespace. The two annotations are required. The rest:uri annotation is an absolute URI, so it starts with a slash, and includes the full path up to, but not including any query string parameters. These tokens allow you to provide any string in that position of the URI, and Mach-II will automatically create an eventArg where the name of the token is the string between the curly braces, and the value is whatever text was entered in that position of the URI.

For example, given a rest:uri of:. All other query string params also become event-args. REST can be used to perform actions that indirectly operate on resources. The REST endpoint will also automatically capture a dot-delimited file extension and return a response with the corresponding Content-Type header.

For example, if you use a URI of:. In addition, Mach-II sets the eventArg format with the value of the input file extension. Alternatively, you can provide the format as a query string parameter.

Any query string parameters are also converted to Mach-II eventArgs, as usual. If you are using your web server's rewriting capability to remove the index. It is also possible to pass the endpoint name defined in the Mach-II config file, shown below and URI as query string parameters, like so:.

Once you have created your endpoint CFC, you need to add just a few lines to your mach-ii.

REST API - Concurrency in REST

There are several annotation based options to configure your REST endpoint methods. Annotations provide syntactical metadata and are embedded in your REST endpoint source code that influence the runtime the behavior of your endpoint. It is easy to access custom metadata for an endpoint method.

You can get all the information you need by getting the restUri object out of the event object inside your endpoint method:. The Content-Length header indicates the size of the document body in bytes and not the length of the document body.

UTF-8 characters in extended regions of the character encoding may use two or more bytes per character. This is why we check the byte size of the document and not Len documentBody instead. This method accepts either named arguments or positional arguments. For any endpoint that returns JSON formatted data, you can optionally supply a callback function name via the 'jsonp' argument. For example:. Tomcat and JRun by default do not parse the request body to form variables i.One advantage of using REST is that you don't have to add references to any SharePoint libraries or client assemblies.

Instead, you make HTTP requests to the appropriate endpoints to retrieve or update SharePoint entities, such as webs, lists, and list items. For a sample that shows you how to do many of these operations in the context of an ASP. For POST operations, any properties that are not required are set to their default values.

If you attempt to set a read-only property as part of a POST operation, the service returns an exception. For MERGE requests, setting properties is optional; any properties that you do not explicitly set retain their current property.

For PUT commands, however, any properties you do not explicitly set are set to their default properties. In the case of recyclable objects, such as lists, files, and list items, this results in a Recycle operation.

It also assumes that you have a valid OAuth access token that is stored in the accessToken variable. You do not need the access token if you make this call from inside an add-in web, as you would in a SharePoint-hosted add-in. Note that you cannot obtain an access token from code that is running on a browser client. You must obtain the access token from code that is running on a server. This request would look a little different if you are writing your add-in in JavaScript while using the SharePoint cross-domain library.

In this case, you don't need to provide an access token.

The following code demonstrates how this request would look if you are using the cross-domain library and want to receive the OData representation of the lists as XML instead of JSON. Because Atom is the default response format, you don't have to include an Accept header. For more information about using the cross-domain library, see Access SharePoint data from add-ins using the cross-domain library.

The code in the following example shows you how to request a JSON representation of all of the lists in a site by using C.

It assumes that you have an OAuth access token that you are storing in the accessToken variable. Many property values are returned when you retrieve a resource, but for some properties, you have to send a GET request directly to the property endpoint.

This is typical of properties that represent SharePoint entities. The following example shows how to get a property by appending the property name to the resource endpoint.

The example gets the value of the Author property from a File resource. One key difference, however, is that you use a POST request. When you create or update an entity, you must provide an OData representation of the entity that you want to create or change in the body of your HTTP request. Another important consideration when creating, updating, and deleting SharePoint entities is that if you aren't using OAuth to authorize your requests, these operations require the server's request form digest value as the value of the X-RequestDigest header.

If you're using the authentication and authorization flow described in Authorization and authentication of SharePoint Add-insyou don't need to include the request digest in your requests. If you're using the JavaScript cross-domain library, SP. RequestExecutor handles getting and sending the form digest value for you. Instead, you can retrieve the value in JavaScript code from the SharePoint page if the page uses the default master pageas shown in the following example, which uses JQuery and creates a list.

The following example shows how to update the list that is created in the previous example. The example changes the title of the list, uses JQuery, and assumes that you are doing this operation in a SharePoint-hosted add-in.

This particular value applies only to lists and list items, and is intended to help you avoid concurrency problems when you update those entities. Otherwise, you should obtain the etag value or a list or list item by performing a GET request that retrieves the entity.
