1. 在使用"render\_template"渲染模板的時候，可以傳遞參數u，以后直接在模板中使用就可以了
2. 如果參數過多，可以將所有的字典放到一個字典中，然后在傳入這個字典參數的時候，使用兩個星號，將字典打散成關鍵參數

   from flask import Flask, Response, jsonify, render\_template  
   app = Flask\(name\)  
   @app.route\("/"\)  
   def hell0\_world\(\):  
   context = {  
   "username":"miku",  
   "age":18,  
   "contry":"china",  
   "childrens":{  
   "name":"abc",  
   "height":180,  
   }  
   }

   return render\_template\("index.html",\*\*context\)  
   if name == 'main':  
   app.run\(debug=True\)

```text
index.html

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>MIKU</title>
</head>
<body>
    這是從模板中渲染的數據
{#    <p>{{ context.username }}</p>#}
{#    <p>{{ context.age }}</p>#}
{#    <p>{{ context.contry }}</p>#}

    <p>{{ username }}</p>
    <p>{{ age }}</p>
    <p>{{ contry }}</p>
    <p>{{ childrens }}</p>
    <p>{{ childrens.name }}</p>
    <p>{{ childrens['name'] }}</p>
</body>
</html>
```
