BugTracker 加入发Mail的功能

BugTracker部署好之后，发现增加bug不能mail提醒。于是补上这个功能记录在此，方法是次要的，主要是找到地方。需要3步。吐槽下Asp的代码风格看的真心蛋疼....

一、发送mail（主要是找到位置）

1.在App_Code中加入MailHelper.cs .

using System;
using System.Net.Mail;
 
public class MailHelper
{
    /// <summary>
    /// 异步发送邮件
    /// </summary>
    /// <param name="toMails"></param>
    /// <param name="subject"></param>
    /// <param name="content"></param>
    public static void SystemSendMail(string toMails, string subject, string content)
    {
 
            Action invokeAction = () => WebMailTo(toMails, subject, content);
            invokeAction.BeginInvoke(Callback, invokeAction);
 
    }
 
    private static void Callback(IAsyncResult ar)
    {
        var action = ar.AsyncState as Action;
        if (action != null) action.EndInvoke(ar);
    }
 
    /// <summary>
    /// Webs the mail to.
    /// </summary>
    /// <param name="toEmails">To emails.</param>
    /// <param name="subject">The subject.</param>
    /// <param name="emailText">The email text.</param>
    /// <returns><c>true</c> if XXXX, <c>false</c> otherwise</returns>
    public static bool WebMailTo(string toEmails, string subject, string emailText)
    {
        #region 此处参数使用时根据需要替换成自己的
        const string server = "172.17.xxx.95"; //此处代表Mail Server地址
        const string formEmail = xxxxx.xxx@xxx.com.cn"; //此处代表系统发邮件的时候的发件人地址
        const string formDispayName = "BugTracker"; //系统发件人的显示名称
        const string formPassword = "xxxxx"; //此处代表系统发邮件的时候的发件人的密码
        const string formDomain = "xxxwj"; //域名
        #endregion
 
        const string systermtxt = "<br/>该邮件为系统自动发送，请勿回复！详情请点击" + "<a href='http://cnwj6iapc016:84/'>这里~</a>";
        var mailMessage = new MailMessage { IsBodyHtml = true };
        mailMessage.To.Add(toEmails);
        mailMessage.From = new MailAddress(formEmail, formDispayName);
        mailMessage.Subject = subject;
        mailMessage.Body = emailText + systermtxt;//此处可以传递一个html
        mailMessage.Priority = MailPriority.High;
        var client = new SmtpClient
        {
            Host = server,
            UseDefaultCredentials = false,
            Credentials = new System.Net.NetworkCredential(formEmail, formPassword, formDomain),
            DeliveryMethod = SmtpDeliveryMethod.Network,
            EnableSsl = false
        };
        bool isSendOk;
        try
        {
            client.Send(mailMessage);//发送Mail
            isSendOk = true;
 
        }
        catch (Exception)
        {
 
            isSendOk = false;
        }
        return isSendOk;
    }
}

2.给在App_Code的dbutil.cs加入个功能函数。

  public static string GetStringById(int id,StringType stringType)
        {
            using (SqlConnection conn = get_sqlconnection())
            {
                var sql = "";
                switch (stringType)
                {
                    case StringType.Email:
                        sql = "select us_email from users where us_id=" + id;
                       break;
                    case StringType.ProjectDefaultUserId:
                       sql = "select pj_default_user from projects where pj_id=" + id;
                        break;
                    case StringType.UserName:
                         sql = "select us_username from users where us_id=" + id;
                        break;
                }
                DataSet ds = new DataSet();
                SqlDataAdapter da = new SqlDataAdapter(sql, conn);
                int c = da.Fill(ds, "table");
                DataRow[] dr = ds.Tables[].Select();
                conn.Close();
                return c !=  ? dr[][].ToString() : "";
            }
        }
 
public enum StringType
    {
        Email,
        ProjectDefaultUserId,
        UserName
    }

3.在App_Code的bug.cs中修改insert_bug 方法。

 sql = sql.Replace("$short_desc", short_desc.Replace("'", "''"));
            sql = sql.Replace("$tags", tags.Replace("'", "''"));
            sql = sql.Replace("$reported_user", Convert.ToString(security.user.usid));
            sql = sql.Replace("$project", Convert.ToString(projectid));
            sql = sql.Replace("$org", Convert.ToString(orgid));
            sql = sql.Replace("$category", Convert.ToString(categoryid));
            sql = sql.Replace("$priority", Convert.ToString(priorityid));
            sql = sql.Replace("$status", Convert.ToString(statusid));
            sql = sql.Replace("$assigned_user", Convert.ToString(assigned_to_userid));
            sql = sql.Replace("$udf", Convert.ToString(udfid));
            sql = sql.Replace("$pcd1", project_custom_dropdown_value1);
            sql = sql.Replace("$pcd2", project_custom_dropdown_value2);
            sql = sql.Replace("$pcd3", project_custom_dropdown_value3);
 
            // 发送mail  这里才是补充的代码。
            var str = string.Format("<div style='padding:20px;border:2px solid green'>{0}维护了与你相关的新的Bug,详细情况请登录Bug管理系统</div>", security.user.username);
            var pid = DbUtil.GetStringById(projectid, StringType.ProjectDefaultUserId);
            if (pid == "")
            {
                pid = "";
            }
            var defaultuserid = Convert.ToInt16(pid);
            if (defaultuserid != )
            {
                MailHelper.SystemSendMail(DbUtil.GetStringById(defaultuserid, StringType.Email), "BugTracker:你有新的bug了", str);
            }
            if (defaultuserid != assigned_to_userid)
            {
                MailHelper.SystemSendMail(DbUtil.GetStringById(assigned_to_userid, StringType.Email), "BugTracker:你有新的bug了", str);
            }

这样子就ok了。增加不过的时候，会发送给抄送人和工程负责人。

同理，如果要在评论更显得 时候也加入mail通知。评论对应的数据库中的表是bug_posts. 插入的方法在App_Code/bug.cs中的

public static int insert_comment（.....） 方法中。

在return之前加入下面的代码：

sql = sql.Replace("$cc", cc.Replace("'", "''"));
                sql = sql.Replace("$internal", btnet.Util.bool_to_string(internal_only));
 
                 DataRow[] drs = DbUtil.GetBugDataRows(bugid);
                if (drs.Count() != )
                {
                    var buguserId = Convert.ToInt16(drs[]["bg_reported_user"]);// 发布bug的人
                    var bugassigneduserId = Convert.ToInt16(drs[]["bg_assigned_to_user"]);//bug抄送的人
                    var projectId = Convert.ToInt16(drs[]["bg_project"]);
                    const string titile = "Bug有新的评论";
                    var bugdesc = drs[]["bg_short_desc"].ToString();
                    var content = string.Format("<div style='padding:20px;border:3px solid blueviolet;'>Bug {0}(Id :{1})有新的评论：<br/><p style='color:gray;font-size:small;background: #ffffe0'>{2}</p></div>", bugdesc, bugid, comment_formated.Replace("'", "''"));
                    if (this_usid != buguserId)//避免是同一人 而重复发送。
                    {
                        MailHelper.SystemSendMail(DbUtil.GetStringById(buguserId,StringType.Email),titile,content);
                    }
                    if (bugassigneduserId !=  && this_usid != bugassigneduserId)//避免是同一人 而重复发送。
                    {
                        MailHelper.SystemSendMail(DbUtil.GetStringById(bugassigneduserId, StringType.Email), titile, content);
                    }
 
                    if (projectId != )
                    {
                        var pduid =Convert.ToInt16(DbUtil.GetStringById(projectId, StringType.ProjectDefaultUserId)) ;
                        if (pduid !=  && this_usid != pduid && pduid != bugassigneduserId)//避免是同一人 而重复发送。
                        {
                            MailHelper.SystemSendMail(DbUtil.GetStringById(pduid, StringType.Email), titile, content);
                        }
                    }
 
                }

另外需要在dbutil.cs中加入一些方法

public static string GetStringById(int id,StringType stringType)
        {
            using (SqlConnection conn = get_sqlconnection())
            {
                var sql = "";
                switch (stringType)
                {
                    case StringType.Email:
                        sql = "select us_email from users where us_id=" + id;
                       break;
                    case StringType.ProjectDefaultUserId:
                       sql = "select pj_default_user from projects where pj_id=" + id;
                        break;
                    case StringType.BugUserId:
                         sql = "select bg_reported_user from bugs where bg_id=" + id;
                        break;
                }
                var ds = new DataSet();
                var da = new SqlDataAdapter(sql, conn);
                var c = da.Fill(ds, "table");
                var dr = ds.Tables[].Select();
                conn.Close();
                return c !=  ? dr[][].ToString() : "";
            }
        }
 
        public static DataRow[] GetBugDataRows(int bugId)
        {
            using (SqlConnection conn = get_sqlconnection())
            {
                var sql = "select * from bugs where bg_id=" + bugId;
                var ds = new DataSet();
                var da = new SqlDataAdapter(sql, conn);
                da.Fill(ds, "table");
                var drs=ds.Tables[].Select();
                conn.Close();
                return drs;
            }
        }

最后效果：

二、自动登录

自动登录也要改改，每次都要点一次。刚开始以为在login打头的文件中，试了几次登录函数是在default.aspx 页面中。

1、在Page_Load中的 if (username_cookie != null) 中加入最后三句，就是判断下cookie。asp中的控件赋值比较神器.... input元素直接可以点出value。

if (username_cookie != null)
     {
     //    Set the user name from the last logon.
          user.Value = username_cookie["name"];
           var pcookie = Request.Cookies["pwd"];
            if (pcookie != null && pcookie.Value!="")
           {
              pw.Value = pcookie.Value;
              on_logon();
          }
     }

2、再在下面的on_logon() 中的 if (authenticated) 中加入下面的代码。 初始的时候加上cookie

var httpCookie = Response.Cookies["pwd"];
if (httpCookie == null)
{
var currentCookie = new HttpCookie("pwd") {Value = pw.Value, Expires = DateTime.Now.AddDays()};
Response.Cookies.Add(currentCookie);
}
else
{
httpCookie.Value = pw.Value;
}

3、处理退出，不然的话人家登录了很难切换用户。

用户点击右上角的logoff的时候，其实是先跳转到了logoff.aspx页面。在页面跳转到defau.aspx之前，清空cookie的值。

 var httpCookie = Response.Cookies["pwd"];
        if (httpCookie != null)
        {
            httpCookie.Value = null;
        }
 
        Response.Redirect("default.aspx?msg=logged+off");

感觉下次就会用上。
