Verify covid cerificate

This section shows how to use C# to send a request to the designed API to verify the certificate

Step 1: Create HttpClient Object with the given ApiKey to send the request to the server.

        
            HttpClient client = new HttpClient();
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            client.DefaultRequestHeaders.Add("ApiKey", "Your Key");

            var URL = "https//covidvalidator.website"; //replace with the correct URL
            client.BaseAddress = new System.Uri("URL");

Step 2: Input the string from QR code and convert it to Json Object.

        
            string qrString = "String from QR code";
            var jObj = JsonSerializer.Serialize(qrString);
            var content = new StringContent(jObj, Encoding.UTF8, "application/json");

Step 3: Send the request using POST method and get the content of the response.

        
            var response = await client.PostAsync("covidverifier", content);
            var responseString = await response.Content.ReadAsStringAsync();

Get Document signer certificates (DSCs)

This section shows how to use C# to send a request to the designed API to Get all DSCs or DSCs from specific country

Step 1: Create HttpClient Object with the given ApiKey to send the request to the server.

        
            HttpClient client = new HttpClient();
            client.DefaultRequestHeaders.Accept.Clear();
            client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
            client.DefaultRequestHeaders.Add("ApiKey", "Your Key");

            var URL = "https//covidvalidator.website"; //replace with the correct URL
            client.BaseAddress = new System.Uri("URL");

Step 2: Send the request using GET method and get the content of the response.

Get all DSCs list that are accepted by Germany:

            
            // Get all DSCs
            var response = await client.GetAsync("covidverifier/dscs/all");
            var responseString = await response.Content.ReadAsStringAsync();

Or Get DSCs list from other country that are accepted by Germany:

            
            // Get DSCs from a country            
            var country = "de"; // Use another country code such as fr if you want to get DSCs from France
            var response = await client.GetAsync($"covidverifier/dscs/{country}");
            var responseString = await response.Content.ReadAsStringAsync();
