RESTful web services don’t follow a prescribed +standard except fpr the protocol that is used which is HTTP, its important +to build RESTful API in accordance with industry best practices to ease +development & increase client adoption. + +In REST Architecture everything is a resource. RESTful web services are light +weight, highly scalable and maintainable and are very commonly used to +create APIs for web-based applications. + +Here are important points to be considered: + + * GET operations are read only and are safe. + * PUT and DELETE operations are idempotent means their result will + always same no matter how many times these operations are invoked. + * PUT and POST operation are nearly same with the difference lying + only in the result where PUT operation is idempotent and POST + operation can cause different result. + + +REST API in SampleVNF +===================== + +In SampleVNF project VNF’s are run under different contexts like BareMetal, +SRIOV, OVS & Openstack etc. It becomes difficult to interact with the +VNF’s using the command line interface provided by the VNF’s currently. + +Hence there is a need to provide a web interface to the VNF’s running in +different environments through the REST api’s. REST can be used to modify +or view resources on the server without performing any server-side +operations. + +REST api on VNF’s will help adapting with the new automation techniques +being adapted in yardstick. + +Web server integration with VNF’s +================================== + +In order to implement REST api’s in VNF one of the first task is to +identify a simple web server that needs to be integrated with VNF’s. +For this purpose “civetweb” is identified as the web server That will +be integrated with the VNF application. + +CivetWeb is an easy to use, powerful, C/C++ embeddable web server with +optional CGI, SSL and Lua support. CivetWeb can be used by developers +as a library, to add web server functionality to an existing application. + +Civetweb is a project forked out of Mongoose. CivetWeb uses an [MITlicense]. +It can also be used by end users as a stand-alone web server. It is available +as single executable, no installation is required. + +In our project we will be integrating civetweb into each of our VNF’s. +Civetweb exposes a few functions which are used to resgister custom handlers +for different URI’s that are implemented. +Typical usage is shown below + + +VNF Application init() +========================= + +Initialize the civetweb library +================================ + +mg_init_library(0); + +Start the web server +===================== +ctx = mg_start(NULL, 0, options); + + +Once the civetweb server is started we can register our URI’s as show below +mg_set_request_handler(ctx, "/config", static_cfg_handler, 0); + +In the above example “/config” is the URI & static_cfg_handler() is +the handler that gets called when a user invokes this URI through +the HTTP client.
