API Automation Using RestSharp [ Multipart/Form Data ]

 

Multipart/Form Data

A HTTP multipart request is a HTTP request that HTTP clients construct to send files and data over to a HTTP Server. It is commonly used by browsers and HTTP clients to upload files to the server.

Swagger Link : https://petstore.swagger.io/#/

Code :  

 [TestClass]
    public class DemoPostOperations
  {
    [Test]
        public void MultipartFormData()
        {
            var client = new RestClient("https://petstore.swagger.io/v2/");
            client.Authenticator = new HttpBasicAuthenticator("api_key", "****");
            var request = new RestRequest("pet/10/uploadImage", Method.POST);
            
            request.AddHeader("Content-Type", "multipart/form-data");
            request.AddHeader("Accept", "application/json");

            request.AddParameter("additionalMetadata", "abc123");
            request.AddFile("file", @"C:\Users\Admin\source\repos\WebserviceAutomation\WebserviceAutomation\Post Operations\Screenshot_1.jpg");

            IRestResponse response = client.Execute(request);
            var resonseContent = response.Content;

        }
 }

Response Body : 

{"code":200,"type":"unknown","message":"additionalMetadata: abc123\nFile uploaded to ./Screenshot_1.jpg, 18091 bytes"}

API Automation Using RestSharp [ Deserialization ]

 

How to Deserialize JSON Response to Class with RestSharp?

 The term Deserialization here means the conversion from the String form of JSON to a Class form. This is also called Object Representation of structured data.

• Add Newtonsoft.json to the project via Nuget Package Manager => Manage Nuget packages for Solutions.

• Create a model class of the json response like this

 public class Users
    {

        public string name { get; set; }
        public string job { get; set; }
        public string id { get; set; }
        public DateTime createdAt { get; set; }

    }

• Make appropriate changes in the code like this

 public class DemoGetTest
    {
        private string BaseUrl = "https://reqres.in/";

        [Test]
        public void DeserializingJsonResponse()
        {
            var restClient = new RestClient(BaseUrl);
            var restRequest = new RestRequest("/api/users?page=2", Method.GET);
            restRequest.AddHeader("Accept", "application/json");
            IRestResponse response = restClient.Execute(restRequest);
            var content = response.Content;

            if (response.IsSuccessful)
            {
                Console.WriteLine("Status Code " + response.StatusCode);
                Console.WriteLine("Response Content " + response.Content);

            }

            //De-serialisation of Response Data 


            Root json = JsonConvert.DeserializeObject<Users>(content);
           
            if(json.data[0].first_name== "Michael")
            {
                Console.WriteLine("operation passed ");
            }

             var jsonobject=JObject.Parse(content);
             int pagevalue =(int)jsonobject.GetValue("page");
           

        }


    }
