Smobiler APP开发 ----登录

    登录页面，布局可以直接拿官方给的登录页面稍作修改就行了。

 目前后端我用的是api接口。

点击登录按钮：

 private void btnLogon_Click(object sender, EventArgs e)
        {
         
            string user = txtUserName.Text.Trim(); ;
            string pwd = txtPassWord.Text.Trim();
            if (user.Length <= 0)
            {
                MessageBox.Show("请输入账号！");
            }
            else
            if (pwd.Length <= 0)
            {
                MessageBox.Show("请输入密码！");
            }
            else
            if (pwd.Length < 4 || pwd.Length > 12)
            {
                MessageBox.Show("密码必须为6-12位！");
            }
            else
            {
                LoadClientData(MobileServer.ServerID + "user", user);
                if (checkRemb.Checked == true)
                {
                    //记住密码
                    LoadClientData(MobileServer.ServerID + "pwd", pwd);
                }
                else
                {
                    //删除客户端数据
                    RemoveClientData(MobileServer.ServerID + "pwd", (object s, ClientDataResultHandlerArgs args) => txtPassWord.Text = "");
                }
                pwd = Md5.Md5Upper32(pwd);
                Client.Session["url"] = "http接口";
                string url = Client.Session["url"].ToString() +"/wapi/OP/UserLogin1?username=" + user + "&password=" + pwd;
                string Data = RequestHttpHelper.LoadData(url);//远程调用app接口
                JsonCommon<UserInfo> js = JsonHelper.DeserializeJson<JsonCommon<UserInfo>>(Data);
                if (js.success == 1)
                {
                    Client.Session["UserInfo"] = js.data[0];
                    SmobilerMain main = new SmobilerMain();
                    Show(main);
                }
                else
                {
                    MessageBox.Show("用户名或者密码错误！");
                }
            }

        }

记住密码：

  private void smobilerForm1_Load(object sender, EventArgs e)
        {
            //读取用户名
            ReadClientData(MobileServer.ServerID + "user", (object sender1, ClientDataResultHandlerArgs e1) =>
            {
                if (String.IsNullOrEmpty(e1.error))
                {
                    txtUserName.Text = e1.Value;
                }
            });
            //读取密码
            ReadClientData(MobileServer.ServerID + "pwd", (object sender1, ClientDataResultHandlerArgs e1) =>
            {
                if (String.IsNullOrEmpty(e1.error))
                {
                    txtPassWord.Text = e1.Value;
                    if (txtPassWord.Text.Length > 0)
                    {
                        checkRemb.Checked = true;
                    }
                }
            });
        }

MD5加密：

  public class Md5
    {
        /// <summary>
        /// MD5加密,保留32位大写
        /// </summary>
        /// <param name="str">加密字符</param>
        /// <returns></returns>
        [Obsolete]
        public static string Md5Upper32(string str)
        {
            return md5(str, 32).ToUpper();
        }

        /// <summary>
        /// MD5加密
        /// </summary>
        /// <param name="str">加密字符</param>
        /// <param name="code">加密位数16/32</param>
        /// <returns></returns>
        [Obsolete]
        public static string md5(string str, int code)
        {
            string strEncrypt = string.Empty;
            if (code == 16)
            {
                strEncrypt = FormsAuthentication.HashPasswordForStoringInConfigFile(str, "MD5").Substring(8, 16);
            }
            else if (code == 32)
            {
                strEncrypt = System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(str, "MD5");
            }

            return strEncrypt;
        }


    }

 

  远程调用API接口的方法：

 public class RequestHttpHelper
    {
        public static string LoadData(string url)
        {
            //创建请求
            HttpWebRequest request = (HttpWebRequest)WebRequest.Create(url);
            //GET请求
            request.Method = "GET";
            request.ReadWriteTimeout = 5000;
            request.ContentType = "text/html;charset=UTF-8";
            HttpWebResponse response = (HttpWebResponse)request.GetResponse();
            Stream myResponseStream = response.GetResponseStream();
            StreamReader myStreamReader = new StreamReader(myResponseStream, Encoding.GetEncoding("utf-8"));
            //返回内容
            string retString = myStreamReader.ReadToEnd();
            return retString;
        }
        /// <summary>
        /// 删除文件
        /// </summary>
        /// <returns></returns>
        public static void DelFile(string strFileName)
        {
            if (File.Exists(strFileName))
            {
                File.Delete(strFileName);
            }
        }
        public static void SendImg(string path, string fileName, string apiUrl)
        {
            //读取文件
            using (var stream = File.OpenRead(path))
            {
                Upload(stream, fileName, apiUrl);//上传文件到API接口
            }
        }
        /// <summary>

            imageIn.Save(ms, System.Drawing.Imaging.ImageFormat.Gif);
            return ms.ToArray();
        }
        /// <summary>

        public Image byteArrayToImage(byte[] byteArrayIn)
        {
            MemoryStream ms = new MemoryStream(byteArrayIn);
            Image returnImage = Image.FromStream(ms);
            return returnImage;
        }

                BinaryReader r = new BinaryReader(stream);
                r.BaseStream.Seek(0, SeekOrigin.Begin);    //将文件指针设置到文件开

                pReadByte = r.ReadBytes((int)r.BaseStream.Length);//文件流

                para = string.Format("stream={0}&fileName={1}", Convert.ToBase64String(pReadByte).Replace("+", " "), fileName);
                byte[] bytePara = Encoding.UTF8.GetBytes(para);


                using (StreamContent sc = new StreamContent(new MemoryStream(bytePara)))
                {
                    sc.Headers.ContentLength = bytePara.Length;
                    sc.Headers.ContentType = new System.Net.Http.Headers.MediaTypeHeaderValue("application/x-www-form-urlencoded");//application/x-www-form-urlencoded

                using (StreamContent sc = new StreamContent(new MemoryStream(bytePara)))

                }
            }

        }
    }

JsonCommon类：

 public class JsonCommon<T>
    {
        public int success { get; set; }
        public List<T> data { get; set; }
    }

UserInfo类：

   public class UserInfo
    {
        public int uid { get; set; }
        public string realname { get; set; }
        public  int departid { get; set; }
        public string departname { get; set; }
        public string phone { get; set; }
        public string email { get; set; }
    }
