RestCmd 1.0.4

RestCmd API Command

RestCmd is a lightweight REST library based on HttpWebRequest that executes API commands. This library runs on .NET Framework 4.0+. This was specifically created on the platform to address legacy programs that still runs on lower versions of the .NET platform. There are lots of REST libraries for newer versions of the .NET. The most popular one is RestSharp.

Basic Usage

The library utilizes the factory pattern. A factory is created with mandatory properties like BaseUri, Authorization, timeouts and headers. The factory object can then be used for successive commands.

To create a new Factory:

 Factory restCmdFactory = new Factory {
     BaseUri = "https://api.restful-api.dev",
     ReadWriteTimeout = 1000,
     Timeout = 1000,
 };

We used the restful-api.dev ready-to-use endpoint for convenience.

Factory has an Authorization Property. It is requires a JWT token. The "Bearer " prefix is automatically prepended.

Upon creation, restCmdFactory can now create a command:

Command cmd = restCmdFactory.Get("/", "objects");

The Get command will fetch data from the default path (/) and objects resource. The objects resource is the resource id. Afterwards, we will call on Execute() to retrieve the contents of the resource.

var res = cmd.Execute<object>();

The Execute method on cmd will retrieve the contents and will attempt to convert it as an object, since it was specified that the result should be an object. Upon inspecting the response, the result should look like an enumerated object:

    "data": null
  },

    "data": {
      "Strap Colour": "Elderberry",
      "Case Size": "41mm"
    }
  },
  {
    "id": "9",
    "name": "Beats Studio3 Wireless",
    "data": {
      "Color": "Red",
      "Description": "High-performance wireless noise cancelling headphones"
    }
  },
  {
    "id": "10",
    "name": "Apple iPad Mini 5th Gen",
    "data": {
      "Capacity": "64 GB",
      "Screen size": 7.9
    }
  },
  {
    "id": "11",
    "name": "Apple iPad Mini 5th Gen",
    "data": {
      "Capacity": "254 GB",
      "Screen size": 7.9
    }
  },
  {
    "id": "12",
    "name": "Apple iPad Air",
    "data": {
      "Generation": "4th",
      "Price": "419.99",
      "Capacity": "64 GB"
    }
  },
  {
    "id": "13",
    "name": "Apple iPad Air",
    "data": {
      "Generation": "4th",
      "Price": "519.99",
      "Capacity": "256 GB"
    }
  }
]

The result is an enumerated object. We can't put out an image of the actual result.

To summarize the actual code:

 Factory restCmdFactory = new Factory {
     BaseUri = "https://api.restful-api.dev",
     ReadWriteTimeout = 1000,
     Timeout = 1000,
 };
 // Specify the resource
 Command cmd = restCmdFactory.Get("/", "objects");
 // Get the resource
 var res = cmd.Execute<object>();
 // Process the result here...
