				+# URTC-demo（React Typescript 版本）
			
 
				+
			
 
				+## 运行步骤
			
 
				+
			
 
				+1. 添加配置
			
 
				+
			
 
				+src/config 目录创建 index.ts 文件，并配置 AppId 和 AppKey，示例代码：
			
 
				+
			
 
				+```
			
 
				+const config = {
			
 
				+  AppId: 'urtc-xxxxxxxx',
			
 
				+  AppKey: 'xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx'
			
 
				+}
			
 
				+
			
 
				+export default config;
			
 
				+```
			
 
				+
			
 
				+> 注：
			
 
				+> 
			
 
				+> 1. AppId 和 AppKey 可从 URTC 产品中获取
			
 
				+> 2. AppKey 不可暴露于公网，建议生产环境时，由后端进行保存并由前端调 API 获取
			
 
				+2. 安装 npm 依赖包
			
 
				+
			
 
				+```
			
 
				+npm install
			
 
				+```
			
 
				+
			
 
				+3. 执行运行命令   
			
 
				+
			
 
				+在本地demo目录下，执行以下操作：    
			
 
				+
			
 
				+
			
 
				+```
			
 
				+npm start
			
 
				+```
			
 
				+
			
 
				+4. 打开页面
			
 
				+
			
 
				+浏览器打开 http://localhost:3000
