以下是一个使用ASP.NET实现注册登录社交系统的简单代码示例:
注册页面(Register.aspx):
```HTML
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Register.aspx.cs" Inherits="Register" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Register</title>
<link href="Styles.css" rel="stylesheet" />
</head>
<body>
<form id="form1" runat="server">
<div>
<h2>Register</h2>
<hr />
<div>
<label for="txtUsername">Username:</label>
<input type="text" id="txtUsername" name="txtUsername" runat="server" />
</div>
<div>
<label for="txtPassword">Password:</label>
<input type="password" id="txtPassword" name="txtPassword" runat="server" />
</div>
<div>
<label for="txtConfirmPassword">Confirm Password:</label>
<input type="password" id="txtConfirmPassword" name="txtConfirmPassword" runat="server" />
</div>
<div>
<label for="txtEmail">Email:</label>
<input type="text" id="txtEmail" name="txtEmail" runat="server" />
</div>
<br />
<div>
<asp:Button ID="btnRegister" runat="server" Text="Register" OnClick="btnRegister_Click" />
</div>
</div>
</form>
</body>
</html>
```
注册页面代码文件(Register.aspx.cs):
```C#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Register : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnRegister_Click(object sender, EventArgs e)
{
string username = txtUsername.Value;
string password = txtPassword.Value;
string confirmPassword = txtConfirmPassword.Value;
string email = txtEmail.Value;
if (password != confirmPassword)
{
// Display error message
return;
}
// Check if username already exists
if (UserExists(username))
{
// Display error message
return;
}
// Hash password
string hashedPassword = HashPassword(password);
// Save user to database
SaveUser(username, hashedPassword, email);
// Redirect to login page
Response.Redirect("Login.aspx");
}
private bool UserExists(string username)
{
// Check if user exists in database
// Return true if user exists, false otherwise
}
private string HashPassword(string password)
{
// Hash password using salt and SHA256 algorithm
// Return hashed password
}
private void SaveUser(string username, string password, string email)
{
// Save user to database
}
}
```
登录页面(Login.aspx):
```HTML
<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Login.aspx.cs" Inherits="Login" %>
<!DOCTYPE html>
<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
<title>Login</title>
<link href="Styles.css" rel="stylesheet" />
</head>
<body>
<form id="form1" runat="server">
<div>
<h2>Login</h2>
<hr />
<div>
<label for="txtUsername">Username:</label>
<input type="text" id="txtUsername" name="txtUsername" runat="server" />
</div>
<div>
<label for="txtPassword">Password:</label>
<input type="password" id="txtPassword" name="txtPassword" runat="server" />
</div>
<br />
<div>
<asp:Button ID="btnLogin" runat="server" Text="Login" OnClick="btnLogin_Click" />
</div>
</div>
</form>
</body>
</html>
```
登录页面代码文件(Login.aspx.cs):
```C#
using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
public partial class Login : System.Web.UI.Page
{
protected void Page_Load(object sender, EventArgs e)
{
}
protected void btnLogin_Click(object sender, EventArgs e)
{
string username = txtUsername.Value;
string password = txtPassword.Value;
// Get user from database
User user = GetUser(username);
if (user == null)
{
// Display error message
return;
}
// Hash entered password
string hashedPassword = HashPassword(password);
if (hashedPassword != user.Password)
{
// Display error message
return;
}
// Set authentication cookie
SetAuthCookie(user);
// Redirect to home page
Response.Redirect("Home.aspx");
}
private User GetUser(string username)
{
// Get user from database
// Return null if user does not exist
}
private string HashPassword(string password)
{
// Hash password using salt and SHA256 algorithm
// Return hashed password
}
private void SetAuthCookie(User user)
{
// Set authentication cookie
}
}
```
以上代码示例中涉及到的 `User` 类需要根据具体情况定义,同时需要实现保存用户信息和验证用户信息的方法。此外,还需要实现设置身份验证 Cookie 的方法。
