REST Service Calls for .NET - 1.2

Description

This extension provides support for some web services calls from C#.

Supported REST client libraries

Transactions

Transaction support is derived from metamodel concepts used to build CAST Imaging Blueprint and structural transaction flows. Entry Points start transactions; Exit Points include both output/boundary concepts and Data Entities manipulated by transactions.

ISO 5055 Structural Rules

Quality support is based on ISO 5055 structural rules available for the selected extension version. Counts are grouped by ISO 5055 characteristic.

Dependencies with other extensions

The REST Service Calls for .NET extension requires that ≥ 1.3.4-funcrel or ≥ 1.4.1-funcrel of the .NET Analyzer  is also installed and used in order to ensure the most complete set of results. This dependency is not automatically handled when downloading the REST Service Calls for .NET extension, therefore you must ensure that the .NET Analyzer is downloaded and installed before starting an analysis.

Features

This extension analyzes web service calls made from C# code through classic fluent APIs. For example with System.Net.Http.HttpClient:

using System;
using System.Net.Http;

class Main
{
    void main()
    {
        var httpClient = new HttpClient();
        
        HttpRequestMessage request = new HttpRequestMessage(HttpMethod.Get,"hello/world");
        
        httpClient.SendAsync(request);
    }
}

Refit

Refit  provides the means to call web services through interfaces with attributes. Therefore, analyzing:

using System.Threading.Tasks;
using Refit;

public interface IGitHubApi
{
    [Get("/users/{user}")]
    Task<string> GetUser(string user);
}

will create:

	Dotnet Post Resource Service	HTTP verb is POST
	Dotnet Put Resource Service	HTTP verb is PUT
	Dotnet Patch Resource Service	HTTP verb is PATCH
