这个示例包括了首页视频列表、视频播放页面、评论功能等基本功能。你可以根据需求进一步扩展,比如添加分类页面、搜索页面、用户系统等。同时也需要在真实环境中替换示例中的接口地址,连接到你自己的服务器获取数据。
前台增加分类页，搜索页面，用户系统，增加后台管理系统
好的,我们来逐步扩展这个短剧视频小程序,添加分类页面、搜索页面、用户系统以及后台管理系统。
**1. 分类页面**
**pages/category/category.wxml**
```xml
<view class="container">
<view class="category-list">
<view class="category-item" wx:for="{{categories}}" wx:key="id">
<navigator url="/pages/video-list/video-list?categoryId={{item.id}}">
<image src="{{item.iconUrl_u}}" mode="aspectFill" class="icon" />
<view class="name">{{item.name}}</view>
</navigator>
</view>
</view>
</view>
```
**pages/category/category.wxss**
```css
.container {
padding: 20rpx;
}
.category-list {
display: flex;
flex-wrap: wrap;
}
.category-item {
width: 25%;
text-align: center;
margin-bottom: 40rpx;
}
.icon {
width: 100rpx;
height: 100rpx;
border-radius: 50%;
}
.name {
font-size: 24rpx;
margin-top: 10rpx;
}
```
**pages/category/category.js**
```javascript
Page({
data: {
categories: []
},
onLoad() {
this.fetchCategories();
},
fetchCategories() {
wx.request({
url: 'https://example.com/api/categories',
success: (res) => {
this.setData({
categories: res.data.categories
});
}
});
}
});
```
**pages/video-list/video-list.wxml**
```xml
<!-- 类似于 index 页面的视频列表部分 -->
```
**pages/video-list/video-list.js**
```javascript
Page({
data: {
categoryId: null,
videos: []
},
onLoad(options) {
this.setData({
categoryId: options.categoryId
});
this.fetchVideos();
},
fetchVideos() {
wx.request({
url: `https://example.com/api/categories/${this.data.categoryId}/videos`,
success: (res) => {
this.setData({
videos: res.data.videos
});
}
});
}
});
```
**2. 搜索页面**
**pages/search/search.wxml**
```xml
<view class="container">
<view class="search-bar">
<input placeholder="搜索视频" bindinput="onInputSearch" />
<button size="mini" type="primary" bindtap="onSearch">搜索</button>
</view>
<view class="video-list">
<!-- 类似于 index 页面的视频列表部分 -->
</view>
</view>
```
**pages/search/search.wxss**
```css
.container {
padding: 20rpx;
}
.search-bar {
display: flex;
align-items: center;
border: 1px solid #eee;
border-radius: 10rpx;
padding: 10rpx;
}
.search-bar input {
flex: 1;
height: 60rpx;
padding: 0 20rpx;
}
```
**pages/search/search.js**
```javascript
Page({
data: {
searchText: '',
videos: []
},
onInputSearch(e) {
this.setData({
searchText: e.detail.value
});
},
onSearch() {
this.fetchVideos();
},
fetchVideos() {
wx.request({
url: `https://example.com/api/videos/search?keyword=${this.data.searchText}`,
success: (res) => {
this.setData({
videos: res.data.videos
});
}
});
}
});
```
**3. 用户系统**
**pages/user/user.wxml**
```xml
<view class="container">

</navigator>
</view>
</view>
```
**pages/user/user.wxss**
```css
.container {
padding: 20rpx;
}
.user-info {
display: flex;
align-items: center;
margin-bottom: 40rpx;
}
.avatar {
width: 100rpx;
height: 100rpx;
border-radius: 50%;

});
}
});
}
});
```
**4. 后台管理系统**
后台管理系统可以使用传统的 Web 应用开发,比如使用 React、Vue 或者 Angular 等前端框架,结合 Node.js 或 Python 等后端语言开发 RESTful API。
这里我们简单列出一些后台管理系统可能需要的功能和页面:
- 登录页面
- 视频管理页面(列表、新增、编辑、删除视频)
- 分类管理页面(列表、新增、编辑、删除分类)
- 用户管理页面(列表、编辑用户信息)
- 评论管理页面(列表、删除评论)
后台管理系统的具体实现需要根据实际需求和技术选型进行开发,这里就不详细展开了。
以上是我们对短剧视频小程序的扩展,包括了分类页面、搜索页面、用户系统以及后台管理系统的基本功能和代码示例。你可以在此基础上根据自己的需求进一步完善和开发。
好的,我们来设计一个基于 React 和 Node.js 的后台管理系统。

这只是一个基本的后台管理系统示例,包括用户登录、视频管理(列表、新增、编辑、删除)等功能。你可以根据实际需求继续扩展,比如添加分类管理、用户管理、评论管理等模块。
此外,你还需要处理一些其他问题,如:
- 用户认证和授权
- 表单验证和错误处理
- 分页和搜索功能
- 上传视频文件
- 部署到服务器等
总的来说,这是一个相对完整的后台管理系统的基本架构和代码示例,希望对大家有所帮助。
增加用户认证和授权，表单验证和错误处理，分叶核搜索功能，上传视频文件，采集视频等功能代码
1. **用户认证和授权**:
- 使用 Flask 内置的 `flask_login` 扩展来实现用户认证和授权功能。
- 创建一个用户模型,包含用户名、密码(使用 `werkzeug.security` 进行密码加密)和其他必要字段。
- 实现登录、注册、注销等视图函数,并在路由中注册。
- 使用 `@login_required` 装饰器保护需要认证的路由。
2. **表单验证和错误处理**:
- 使用 Flask 内置的 `flask_wtf` 扩展实现表单验证。
- 定义表单类,包含必要的字段和验证规则(如长度、格式等)。
- 在视图函数中实例化表单,并在模板中渲染表单。
- 处理表单提交,验证表单数据,并显示错误消息。
3. **分页搜索功能**:
- 使用 Flask 内置的 `Pagination` 类实现分页功能。
- 在视图函数中查询数据,并根据请求参数(如页码、每页显示条数等)计算分页对象。
- 在模板中渲染分页导航链接。
4. **上传视频文件**:
- 使用 Flask 内置的 `request.files` 获取上传的文件。
- 使用 `
werkzeug.utils.secure_filename` 函数获取安全的文件名。
- 将文件保存到服务器的指定目录。
5. **采集视频**:
- 使用第三方库(如 `youtube-dl`)从视频网站(如 YouTube)采集视频。
- 在视图函数中调用第三方库的 API,传入视频链接或其他必要参数。
- 将采集到的视频保存到服务器的指定目录。
以下是一些示例代码片段:
**用户认证和授权**:
```python
from flask import Flask, render_template, redirect, url_for, flash
from flask_login import LoginManager, UserMixin, login_user, logout_user, login_required
from werkzeug.security import generate_password_hash, check_password_hash
app = Flask(__name__)
login_manager = LoginManager(app)
class User(UserMixin):
def __init__(self, id, username, password):
self.id = id
self.username = username
self.password_hash = generate_password_hash(password)
def check_password(self, password):
return check_password_hash(self.password_hash, password)
users = {
1: User(1, 'admin', 'password')
}
@login_manager.user_loader
def load_user(user_id):
return users.get(int(user_id))
@app.route('/login', methods=['GET', 'POST'])
def login():
if request.method == 'POST':
username = request.form.get('username')
password = request.form.get('password')
user = next((u for u in users.values() if u.username == username), None)
if user and user.check_password(password):
login_user(user)
return redirect(url_for('index'))
flash('Invalid username or password', 'error')
return render_template('login.html')
@app.route('/logout')
@login_required
def logout():
logout_user()
return redirect(url_for('index'))
```
**表单验证和错误处理**:
```python
from flask import Flask, render_template, request, flash
from flask_wtf import FlaskForm
from wtforms import StringField, PasswordField, SubmitField
from wtforms.validators import DataRequired, Length, EqualTo
app = Flask(__name__)
app.config['SECRET_KEY'] = 'your_secret_key'
class RegistrationForm(FlaskForm):
username = StringField('Username', validators=[DataRequired(), Length(min=4, max=20)])
password = PasswordField('Password', validators=[DataRequired(), Length(min=6)])
confirm_password = PasswordField('Confirm Password', validators=[DataRequired(), EqualTo('password')])
submit = SubmitField('Register')
@app.route('/register', methods=['GET', 'POST'])
def register():
form = RegistrationForm()
if form.validate_on_submit():
# 处理注册逻辑
flash('Registration successful!', 'success')
return redirect(url_for('index'))
return render_template('register.html', form=form)
```
**分页搜索功能**:
```python
from flask import Flask, render_template, request
from flask_sqlalchemy import SQLAlchemy
from flask_paginate import Pagination, get_page_args
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///database.db'
db = SQLAlchemy(app)
class Video(db.Model):
id = db.Column(db.Integer, primary_key=True)
title = db.Column(db.String(100), nullable=False)
# 其他字段...
@app.route('/search', methods=['GET'])
def search():
page, per_page, offset = get_page_args(page_parameter='page', per_page_parameter='per_page')
search_query = request.args.get('q', '')
videos = Video.query.filter(Video.title.like(f'%{search_query}%')).offset(offset).limit(per_page).all()
total = Video.query.filter(Video.title.like(f'%{search_query}%')).count()
pagination = Pagination(page=page, per_page=per_page, total=total, search=True, record_name='videos')
return render_template('search.html', videos=videos, pagination=pagination, search_query=search_query)
```
**上传视频文件**:
```python
from flask import Flask, render_template, request
from werkzeug.utils import secure_filename
import os
app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = 'uploads/'
@app.route('/upload', methods=['GET', 'POST'])
def upload():
if request.method == 'POST':
file = request.files['video']
if file:
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
return 'File uploaded successfully'
return render_template('upload.html')
```
**采集视频**:
```python
from flask import Flask, render_template, request
import youtube_dl
app = Flask(__name__)
@app.route('/download', methods=['GET', 'POST'])
def download():
if request.method == 'POST':
video_url = request.form['video_url']
ydl_opts = {}
with youtube_dl.YoutubeDL(ydl_opts) as ydl:
ydl.download([video_url])
return 'Video downloaded successfully'
return render_template('download.html')
```
这些只是示例代码,你可能需要根据具体需求进行调整和扩展。同时,还需要注意安全性、错误处理等方面的考虑。
