## ASP领导信箱源码解析及实现

### 背景介绍

随着信息技术的发展，电子政务逐渐成为政府与市民沟通的重要桥梁，传统的信件投递方式存在时间周期长、信息传递不及时等问题，无法满足市民对于快速反馈和解决问题的期望，引入现代化的领导信箱系统成为必然选择，本文将详细解析ASP技术构建的领导信箱系统的实现过程，包括其功能模块、代码结构以及关键代码片段。

### 系统架构

1. **前端界面**：用户可以通过浏览器访问系统，进行写信、查看信件等操作。

2. **后端服务**：采用ASP技术开发，处理用户的请求并返回相应的结果。

3. **数据库**：使用SQL Server存储数据，包括用户信息、信件内容等。

4. **安全性**：通过身份验证机制确保只有合法用户可以访问系统。

### 功能模块

1. **用户注册与登录**：用户需要先注册并登录才能使用系统。

2. **写信功能**：用户可以填写收件人、标题、内容等信息发送邮件。

3. **收件箱管理**：用户可以查看已收到的邮件列表，并进行查看详情、回复等操作。

4. **发件箱管理**：用户可以查看自己发送的邮件状态（已读/未读）。

5. **草稿箱管理**：用户可以保存未完成的邮件到草稿箱，以便后续编辑或发送。

6. **废纸篓管理**：用户可以恢复或彻底删除不再需要的邮件。

7. **系统设置**：管理员可以管理系统配置，如修改密码、备份数据等。

### 代码实现

#### 1. 数据库设计

我们需要创建一个数据库来存储用户信息、邮件信息等数据，以下是一个简单的表结构示例：

```sql

-创建数据库

CREATE DATABASE LeaderMailbox;

GO

-使用数据库

USE LeaderMailbox;

GO

-创建用户表

CREATE TABLE Users (

UserID INT PRIMARY KEY IDENTITY(1,1),

Username NVARCHAR(50) NOT NULL UNIQUE,

Password NVARCHAR(50) NOT NULL,

Email NVARCHAR(100) NOT NULL UNIQUE

);

GO

-创建邮件表

CREATE TABLE Emails (

EmailID INT PRIMARY KEY IDENTITY(1,1),

SenderID INT FOREIGN KEY REFERENCES Users(UserID),

ReceiverID INT FOREIGN KEY REFERENCES Users(UserID),

Subject NVARCHAR(255) NOT NULL,

Content TEXT NOT NULL,

Status INT DEFAULT 0, -0: draft, 1: sent, 2: received

SendTime DATETIME,

ReceiveTime DATETIME

);

GO

```

#### 2. 用户注册与登录

用户注册页面 `register.asp`：

```asp

```

用户注册处理逻辑 `register_do.asp`：

```asp

<%

Dim conn, connStr, sql

Set conn = Server.CreateObject("ADODB.Connection")

connStr = "Provider=SQLOLEDB;Data Source=(local);Initial Catalog=LeaderMailbox;User ID=sa;Password=yourpassword"

conn.Open connStr

Dim username, password, email

username = Request.Form("username")

password = Request.Form("password")

email = Request.Form("email")

sql = "INSERT INTO Users (Username, Password, Email) VALUES (@username, @password, @email)"

Set cmd = Server.CreateObject("ADODB.Command")

With cmd

.ActiveConnection = conn

.CommandText = sql

.Parameters.Append .CreateParameter("@username", adVarChar, adParamInput, 255, username)

.Parameters.Append .CreateParameter("@password", adVarChar, adParamInput, 255, password)

.Parameters.Append .CreateParameter("@email", adVarChar, adParamInput, 255, email)

.Execute()

End With

Response.Redirect("login.asp")

%>

```

用户登录页面 `login.asp`：

```asp

```

用户登录处理逻辑 `login_do.asp`：

```asp

<%

Dim conn, connStr, sql, rs

Set conn = Server.CreateObject("ADODB.Connection")

connStr = "Provider=SQLOLEDB;Data Source=(local);Initial Catalog=LeaderMailbox;User ID=sa;Password=yourpassword"

conn.Open connStr

Dim username, password

username = Request.Form("username")

password = Request.Form("password")

sql = "SELECT * FROM Users WHERE Username=@username AND Password=@password"

Set cmd = Server.CreateObject("ADODB.Command")

With cmd

.ActiveConnection = conn

.CommandText = sql

.Parameters.Append .CreateParameter("@username", adVarChar, adParamInput, 255, username)

.Parameters.Append .CreateParameter("@password", adVarChar, adParamInput, 255, password)

Set rs = .Execute

End With

If Not rs.EOF Then

Session("UserID") = rs("UserID")

Response.Redirect("inbox.asp")

Else

Response.Write "用户名或密码错误！"

End If

%>

```

#### 3. 写信功能

写信页面 `write_mail.asp`：

```asp

```

conn.Open connStr

senderID = Session("UserID")

receiverID = Request.Form("receiver")

subject = Request.Form("subject")

content = Request.Form("content")

sendTime = Now()

sql = "INSERT INTO Emails (SenderID, ReceiverID, Subject, Content, Status, SendTime) VALUES (@senderID, @receiverID, @subject, @content, 1, @sendTime)"

Set cmd = Server.CreateObject("ADODB.Command")

With cmd

.ActiveConnection = conn
