Uploading Screenshots to Spira using the v5.0 REST API

[Note this article uses the v5.0 REST API, please refer to KB604 for the newer v6.0 REST API]

In this example, we're using the following API:

POST: projects/{project_id}/documents/file?filename={filename}&tags={tags}&folder_id={folder_id}&document_type_id={document_type_id}&artifact_type_id={artifact_type_id}&artifact_id={artifact_id}

Description

Adds a new document (file) into the system and associates it with the provided artifact (optional) and project folder/type (optional)

The file must be converted into an array of bytes. Include this and nothing else into the body of the request. The array will take the form of: [number1, number2, number3, and so on], where each number is a value between 0 and 255.

How to Execute

To access this REST web service, you need to use the following URL (make sure to replace any parameters (eg {project_id}) with the relevant value (eg 1).

Sample Code

 /// <summary>
        /// Uploads the file
        /// </summary>
        private void button1_Click(object sender, EventArgs e)
        {
            //Create the full URL
            string url = this.txtUrl.Text.Trim() + "/Services/v5_0/RestService.svc/projects/{project_id}/documents/file?filename={filename}";
            string projectId = this.txtProject.Text.Trim();
            string filename = Path.GetFileName(this.txtFilename.Text);
            url = url.Replace("{project_id}", projectId);
            url = url.Replace("{filename}", filename);

            //Create the HTTP Post
            HttpWebRequest request = WebRequest.Create(url) as HttpWebRequest;
            request.ContentType = "application/json";
            request.Method = "POST";

            //Add the authentication
            string base64Credentials = GetEncodedCredentials();
            request.Headers.Add("Authorization", "Basic " + base64Credentials);

            //Read the file and turn into JSON byte array
            byte[] contents = File.ReadAllBytes(this.txtFilename.Text);
            string json = "[";
            bool first = true;
            foreach (byte item in contents)
            {
                if (!first)
                {
                    json += ",";
                }
                else
                {
                    first = false;
                }
                json += item.ToString();
            }
            json += "]";
            
            //Add the filename body
            using (StreamWriter writer = new StreamWriter(request.GetRequestStream()))
            {
                //writer.Write("[0,0,0,0,0,0,0,0,0,0,0,0,0]");
                writer.Write(json);
            }

            //Fire the query and get the response
            HttpWebResponse response = request.GetResponse() as HttpWebResponse;
            string result = string.Empty;
            using (StreamReader reader = new StreamReader(response.GetResponseStream()))
            {
                result = reader.ReadToEnd();
            }

            MessageBox.Show("Done!");
        }

        /// <summary>
        /// Gets the base64-encoded login/password
        /// </summary>
        /// <returns></returns>
        private string GetEncodedCredentials()
        {
            string mergedCredentials = string.Format("{0}:{1}", this.txtLogin.Text.Trim(), this.txtPassword.Text.Trim());
            byte[] byteCredentials = UTF8Encoding.UTF8.GetBytes(mergedCredentials);
            return Convert.ToBase64String(byteCredentials);
