Restful Services

AbstractModern RESTful services expose RESTful APIs to integrate with diversified applications. Most RESTful API parameters are weakly typed, which greatly increases the possible input value space. This poses difficulties for automated testing tools to generate effective test cases to reveal web service defects related to parameter validation. We call this phenomenon the type collapse problem. To remedy this problem, we introduce FET (Format-encoded Type) techniques, including the FET, the FET lattice, and the FET inference to model fine-grained information for API parameters. Enhanced by FET techniques, automated testing tools can generate targeted test cases. We demonstrate Leif, a trace-driven fuzzing tool, as a proof-of-concept implementation of FET techniques. Experiment results on 27 commercial services show that FET inference precisely captures documented parameter definitions, which helps Leif to discover 11 new bugs and reduce $$72\% \sim 86\%$$ 72 % ∼ 86 % fuzzing time as compared to state-of-the-art fuzzers.

Pengembangan sistem informasi membutuhkan interoperabilitas dalam lingkungan yang heterogen, dilihat dari sistem operasi, perangkat lunak, bahasa pemrograman, dan basis data, sehingga dapat saling berkomunikasi dan bertukar data atau informasi. RESTful web service dapat digunakan sebagai salah satu teknologi untuk mewujudkan interoperabilitas. Sebuah studi kasus tentang aplikasi perpustakaan telah digunakan dalam penelitian ini. Aplikasi tersebut dibangun dengan Slim Framework PHP untuk sisi server dan Visual Basic pada sisi client. Komunikasi antara client dan server menggunakan HTTP method yaitu GET, POST, PUT, dan DELETE. Pengujian telah dilakukan untuk melihat performa dari web service yang telah dikembangkan menggunakan perangkat lunak Postman. Hasil dari penelitian ini menunjukkan bahwa, aplikasi client dapat mengakses web service yang disediakan di sisi server sebagai wujud interoperabilitas.   Information development systems need interoperability in heterogeneous environments, seen from operating systems, software, programming languages, and databases, so that they can communicate and exchange data or information. RESTful web services can be used as one of the technologies to realize interoperability. As case studies build library applications using PHP Slim Framework on the server side, while Visual Basic programming language is used on the client side. Communication Between client and server using HTTP Method that is GET, POST, PUT, and DELETE. Testing has been done to see the performance of web service functionality that has been developed using Postman software. The result shows that client applications can access the web services provided on the server side as a form of interoperability.

In order to make the Web services, web sites in Java more powerful and flexible, building unified web applications is vital important. By introducing a new style─Representational State Transfer (REST), this paper studied the Java RESTful frameworks and the ways to develop Restful Web Service in Java. The RESTful frameworks in Java can effectively simplify the web development in many ways.

Device Location

The variety of Machine-to-Machine (M2M) applications based on very heterogeneous forms of platforms, technology, and data models has resulted in vertical solutions where interoperability is very limited. In order to develop horizontal platforms across different business domains, networks and devices, it is necessary to outline generic capabilities. Service Capabilities provide data mediation functions that may be shared by different applications through application programming interfaces. The paper presents an approach to design RESTful Web Services for access to location and presence status information of M2M devices. The Device Reachability Service Capability provides access to device location and allows device presence information to be registered and obtained. Web Service operations are identified by analysis on typical use cases. M2M device reachability information is modelled as REST resources organized in a tree structure. Web Service performance characteristics are evaluated by simulation.

Restful Services

In the internet environment, web services based on representational state transfer (REST) have become the de facto standard. The addition of semantics is intended to enhance the description of web services with information that enables automatic agents to understand their data. However, the existence of different languages to semantically describe services makes it difficult to discover and select the service that best meets a requirement. Furthermore, relatively few proposals have a RESTful service semantic description, making the discovery process for RESTful services more difficult. This work proposes a RESTful semantic web service discovery architecture based on semantic interfaces (SERIN). SERIN is an ontology with annotations that semantically describe RESTful web services. This architecture enables software agents to automatically discover and make service calls in order to execute a determined task.

We present an architecture for field-programmable gate arrays (FPGAs) to expose RESTful web services. This architecture allows clients to access accelerated web services from any platform and programming language that can perform RESTful API calls. By using this architecture, the client's application benefits from a high throughput and low latency web service interface. Traditionally, FPGAs are deployed in CPU-centric infrastructures as worker devices in the form of accelerators. However, for FPGA-centric applications, the overhead of a host CPU diminishes the performance, scalability and energy efficiency. cloudFPGA solves these issues by deploying FPGAs as standalone, disaggregated resources in the DC. Building on top of the cloudFPGA platform, the presented architecture simplifies the integration of FPGA-accelerated functions with cloud applications. A configurable hardware block that can be generated from an OpenAPI-based specification of the web service is used to deploy an FPGA-based application. We compare a natural language processing (NLP) application that is exposed as a web service using the traditional server infrastructure and our RESTful service layer. Measurements show an improvement of 20x in terms of throughput and 4x reduction in mean latency.

Abstraction Principles

This chapter aims to present a general overview of today's dominant software architectural style for developing web services, namely REST, by comparing the core elements of this paradigm with the big web service model. The study evaluates the HTTP requests, responses, and thus, the SOAP/JSON payloads involved in consuming a big web service and a RESTful service that is developed in the ASP.NET Core Web API framework. After summarizing the REST constraints, the chapter elucidates how the example RESTful web service satisfies these constraints and lists some scenarios suited to each paradigm. The study notes the object-oriented elements that are inherent in RESTful services, specifically how polymorphism and abstraction principles can be applied to RESTful services.
