Many Cloud-based platforms, such as CloudStack, make available an API (Application Programming Interface) for augmenting and controlling infrastructure on appeal.

2. Many Cloud-based platforms, such as
CloudStack, make available an API (Application
Programming Interface) for augmenting and
controlling infrastructure on appeal. One has an
alternative to either use current apps or develop
their own. If one wishes to build up from
scrape, each amendment to the API comes up as a
challenge. Is there a way of avoiding this issue? Is
it feasible to create a client that certifies harmony
with API alteration? The purpose of this post is to
point out the way to produce a lively PHP API client
on the idea of a symbol of concept. The client ought
to be able to range its own web app and 3rd party
apps.
3. CloudStack
The Apache CloudStack is an open-source step to
encourage the service model IaaS (Infrastructure
as a Service) in accordance with which the
computer infrastructure is hired when required (on
appeal), in contrast to conventional purchase
models. The CloudStack platform gives the
administration and augmenting of VMs. This
incorporates a Management Server and expansions
to industry-standard hypervisor package (eg.
vSphere, XenServer, KVM), that are added on the
cloud host.
4. As a Web App Framework: Symfony2
Symfony2 is used for the growth of the client. The
subsequent are the numbers of the factors that can
decide in favour of using the complete stack HTTP
framework:
Extremely performing HTTP Framework
It has a very simple composition and has an error
management
It is completely modularized
It is complied to deep-rooted principles
5. The Concept
Using web-scraping, appropriate information may
be pulled out from the API documentation, through
which, in-turn, the PHP code may be produced for
the client API. In comparison to the manual input,
this way of doing things may save a plenty of your
time and few errors are also barred. By employing a
web-scraper, it's believed that the API
documentation is absolute and accurate, also if
that's not the matter, that the client (or components
of it) won't work correctly.
6. Requirements
In order to understand the enterprising CloudStack
client, the subsequent tool or components are used:
Twig Template Engine
It is used for producing the PHP classes
Guzzle Http Client
Used for contacting with the HTTP API
Data Collector / Symfony Profiler
This collects the logs and further rebounds them in
a human readable format
7. Symfony DOM Crawler
It pulls out the vital data from HTML docs
Symfony Finder
It is used for file system activities
Monolog Logger
It logs the requests and linked errors / information
from the API Client
