Vue页面渲染系统
1. 概述
Vue页面渲染是AI UI生成系统的重要输出模块,负责将结构化的UI-DSL数据转换为可运行的Vue页面代码。本章详细介绍基于Jinja2模板引擎的Vue渲染系统实现,包括组件生成、UniApp框架支持、主题系统集成和代码优化技巧。
2. Vue渲染引擎架构
2.1 整体架构图
UI-DSL -> Vue渲染器 -> 模板引擎 -> Vue组件 -> 可运行代码

JSON数据 VueRenderer Jinja2 组件生成 最终Vue文件
2.2 核心渲染类
系统使用 VueRenderer 类封装Vue页面渲染逻辑:
class VueRenderer:
"""Vue页面渲染器 - 核心Vue渲染类"""
def __init__(self, config_path: str = "config/model_config.yaml",
tokens_path: str = "config/ui_tokens.json"):
"""初始化渲染器"""
with open(config_path, 'r', encoding='utf-8') as f:
self.config = yaml.safe_load(f)
with open(tokens_path, 'r', encoding='utf-8') as f:
self.tokens = json.load(f)
# 加载Vue模板
self.templates = self._load_templates()
3. 模板系统设计
3.1 基础模板结构

"""加载Vue模板"""
