A great resource to pick the correct HTTP error code for your API: http://www.codetinkerer.com/2015/12/04/choosing-an-http-status-code.html An excerpt from the article: Where to start: 2XX/3XX: 4XX: 5XX:
I have posted the complete set of demos for SOAP on CodeCentral as item 28789. These contain every single one of the Delphi 2007 era SOAP demos from the WebServices folder, now updated for Delphi XE and XE2, including converting the old WAD servers into new INDY VCL servers. You’d think that was impressive, except … Read more
Less overhead (no SOAP envelope to wrap every call in) Less duplication (HTTP already represents operations like DELETE, PUT, GET, etc. that have to otherwise be represented in a SOAP envelope). More standardized – HTTP operations are well understood and operate consistently. Some SOAP implementations can get finicky. More human readable and testable (harder to … Read more
A web service typically offers a WSDL from which you can create client stubs automatically. Web Services are based on the SOAP protocol. ASP.NET Web API is a newer Microsoft framework which helps you to build REST based interfaces. The response can be either JSON or XML, but there is no way to generate clients … Read more
For user check, just post get the access token as accessToken and post it and get the response https://www.googleapis.com/oauth2/v1/tokeninfo?access_token=accessToken you can try in address bar in browsers too, use httppost and response in java also response will be like { “issued_to”: “xxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com”, “audience”: “xxxxxxxxxxxxxxx-xxxxxxxxxxxxxxxxxxxxxxxxxx.apps.googleusercontent.com”, “user_id”: “xxxxxxxxxxxxxxxxxxxxxxx”, “scope”: “https://www.googleapis.com/auth/userinfo.profile https://gdata.youtube.com”, “expires_in”: 3340, “access_type”: “offline” } The … Read more
A simple RESTful pattern for batches is to make use of a collection resource. For example, to delete several messages at once. DELETE /mail?&id=0&id=1&id=2 It’s a little more complicated to batch update partial resources, or resource attributes. That is, update each markedAsRead attribute. Basically, instead of treating the attribute as part of each resource, you … Read more
A WSDL is an XML document that describes a web service. It actually stands for Web Services Description Language. SOAP is an XML-based protocol that lets you exchange info over a particular protocol (can be HTTP or SMTP, for example) between applications. It stands for Simple Object Access Protocol and uses XML for its messaging … Read more
HTTPS secures the transmission of the message over the network and provides some assurance to the client about the identity of the server. This is what’s important to your bank or online stock broker. Their interest in authenticating the client is not in the identity of the computer, but in your identity. So card numbers, … Read more
A simple definition: A web service is a function that can be accessed by other programs over the web (HTTP). For example, when you create a website in PHP that outputs HTML, its target is the browser and by extension the human reading the page in the browser. A web service is not targeted at … Read more
Consider the following example of HTTP APIs that model orders being placed in a restaurant. The RPC API thinks in terms of “verbs”, exposing the restaurant functionality as function calls that accept parameters, and invokes these functions via the HTTP verb that seems most appropriate – a ‘get’ for a query, and so on, but … Read more
