如何从C＃应用程序向BugTracker.NET提交错误？

Question

Reading the documentation page of BugTracker.NET
BugTracker.NET API Documentation I realized that I need to use GET or POST which, I have to admit, I'm not very good at. I was wondering:

• Is there a library that could be used to easily submit bugs to BugTracker.NET from a C# application (or VB.NET) ?
  Or,
  
• If there's no library. How can use GET or POST to submit bugs to BugTracker.NET ?

Answer 1

Check this simple example from the documentation of how to make a POST request using .Net. Just make sure to set up the variables being POSTed in according to BugTracker.NET API requirements.

Answer 2

Below is the code from BugTracker.NET's service which reads emails from a pop3 server and then submits them as bugs to the insert_bug.aspx page. But it doesn't have to be this complicated.

Just invoking this URL will also work:

http:\\YOUR-HOST\insert_bug.aspx?username=YOU&password=YOUR-PASSWORD&short_desc=This+is+a+bug

The more complicated code:

string post_data = "username=" + HttpUtility.UrlEncode(ServiceUsername)
                + "&password=" + HttpUtility.UrlEncode(ServicePassword)
                + "&projectid=" + Convert.ToString(projectid)
                + "&from=" + HttpUtility.UrlEncode(from)
                + "&short_desc=" + HttpUtility.UrlEncode(subject)
                + "&message=" + HttpUtility.UrlEncode(message);

            byte[] bytes = Encoding.UTF8.GetBytes(post_data);


            // send request to web server
            HttpWebResponse res = null;
            try
            {
                HttpWebRequest req = (HttpWebRequest) System.Net.WebRequest.Create(Url);


                req.Credentials = CredentialCache.DefaultCredentials;
                req.PreAuthenticate = true; 

                //req.Timeout = 200; // maybe?
                //req.KeepAlive = false; // maybe?

                req.Method = "POST";
                req.ContentType= "application/x-www-form-urlencoded";
                req.ContentLength=bytes.Length;
                Stream request_stream = req.GetRequestStream();
                request_stream.Write(bytes,0,bytes.Length);
                request_stream.Close();
                res = (HttpWebResponse) req.GetResponse();
            }
            catch (Exception e)
            {
                write_line("HttpWebRequest error url=" + Url);
                write_line(e);
            }

            // examine response

            if (res != null) {

                int http_status = (int) res.StatusCode;
                write_line (Convert.ToString(http_status));

                string http_response_header = res.Headers["BTNET"];
                res.Close();

                if (http_response_header != null)
                {
                    write_line (http_response_header);

                    // only delete message from pop3 server if we
                    // know we stored in on the web server ok
                    if (MessageInputFile == ""
                    && http_status == 200
                    && DeleteMessagesOnServer == "1"
                    && http_response_header.IndexOf("OK") == 0)
                    {
                        write_line ("sending POP3 command DELE");
                        write_line (client.DELE (message_number));
                    }
                }
                else
                {
                    write_line("BTNET HTTP header not found.  Skipping the delete of the email from the server.");
                    write_line("Incrementing total error count");
                    total_error_count++;
                }
            }
            else
            {
                write_line("No response from web server.  Skipping the delete of the email from the server.");
                write_line("Incrementing total error count");
                total_error_count++;
            }

Answer 3

I was using that method but did not like sending the password along with the submitted bug. For various reasons, we are using the internal BugTracker password system and not LDAP authentication, so their BugTracker passwords are not known to us. In my case, all of our users are authorized to submit bugs, and their login is their LAN ID. So, from their authenticated instance of the application, I collect their reported issue, capture the project ID, program and class where they are reporting the issue, and call a stored procedure in the BugTracker DB to directly insert the item.

The negative of course is that this is directly into the database and potentially could cause issues with future upgrades, but it is working well for us now.

Answer 4

Thank you all for your answers. Using your answers and other resources on the web, I've put together a method for submitting a new bug to BugTracker.NET
The method returns a boolean value indicating success or failure and it displays a message to the user with the status.
This behavior could be changed to match your needs. The method uses POST method to submit bugs which helps to submit any long text in the comment (I've tried to submit the content of a log file in the comments and it worked).

Here's the code:

public bool SubmitBugToBugTracker(string serverName,
                                        bool useProxy,
                                        string proxyHost,
                                        int proxyPort,
                                        string userName,
                                        string password,
                                        string description,
                                        string comment,
                                        int projectId)
    {
        if (!serverName.EndsWith(@"/"))
        {
            serverName += @"/";
        }
        string requestUrl = serverName + "insert_bug.aspx";
        string requestMethod = "POST";
        string requestContentType = "application/x-www-form-urlencoded";
        string requestParameters = "username=" + userName
                                  + "&password=" + password
                                  + "&short_desc=" + description
                                  + "&comment=" + comment
                                  + "&projectid=" + projectId;
        // POST parameters (postvars)
        byte[] buffer = Encoding.ASCII.GetBytes(requestParameters);
        // Initialisation
        HttpWebRequest WebReq = (HttpWebRequest)WebRequest.Create(requestUrl);
        // Add proxy info if used.
        if (useProxy)
        {
            WebReq.Proxy = new WebProxy(proxyHost, proxyPort);
        }

        // Method is POST
        WebReq.Method = requestMethod;
        // ContentType, for the postvars.
        WebReq.ContentType = requestContentType;
        // Length of the buffer (postvars) is used as contentlength.
        WebReq.ContentLength = buffer.Length;
        // Open a stream for writing the postvars
        Stream PostData = WebReq.GetRequestStream();
        //Now we write, and afterwards, we close. Closing is always important!
        PostData.Write(buffer, 0, buffer.Length);
        PostData.Close();
        // Get the response handle, we have no true response yet!
        HttpWebResponse WebResp = (HttpWebResponse)WebReq.GetResponse();
        // Read the response (the string)
        Stream Answer = WebResp.GetResponseStream();
        StreamReader _Answer = new StreamReader(Answer);
        string responseStream = _Answer.ReadToEnd();

        // Find out if bug submission was successfull.
        if (responseStream.StartsWith("OK:"))
        {
            MessageBox.Show("Bug submitted successfully.");
            return true;
        }
        else if (responseStream.StartsWith("ERROR:"))
        {
            MessageBox.Show("Error occured. Bug hasn't been submitted.\nError Message: " + responseStream);
            return false;
        }
        else
        {
            MessageBox.Show("Error occured. Bug hasn't been submitted.\nError Message: " + responseStream);
            return false;
        }
    }
