";
let num = 10;
await ctx.render("index", {
title,
list,
content,
num,
});
});
```

```html
Document
普通模版
ejs循环输出模版
-
<%= list[i] %>
<%for(var i=0;i
<%}%>
原文输出标签
<%- content %>
条件判断
<% if(num> 20){ %>
大于20
<% }else{ %>
小于20
<% }
%>

```js
npm install formidable@v2
```
使用
```js
const path = require("node:path");
const formidable = require("formidable");
router.post("/", async (ctx, next) => {
const form = formidable({
multiples: true,
// 设置上传文件的保存目录
uploadDir: path.join(__dirname, "../public/uploads"),
// 保存文件后缀
keepExtensions: true,
// 修改文件名 必须返回一个字符串即：新的存储文件名称
filename: (name, ext, part, form) => {
return `ttttt${ext}`;
},
});
await new Promise((resolve, reject) => {
form.parse(ctx.req, (err, fields, files) => {
if (err) return reject(err);
// files.file file就是前端上传的字段名称
ctx.body = { fields, files: files.file };
resolve();
});
});
return await next();
});
```
## jsonwebtoken
下载
```js
npm install jsonwebtoken
```
生成 token
```js
const jwt = require("jsonwebtoken");
const token = jwt.sign(payload, JWTSECRET, { expiresIn: 60 * 60 * 24 });
```
验证 token
```js
jwt.verify(token, JWTSECRET);
```
### 报错 Expected \"payload\" to be a plain object.(翻译结果为：“payload”应为纯对象。)
返回的不是纯对象 == `res._doc`
```js
const res = await UserModel.create(body);
const token = jwt.sign(res._doc, JWTSECRET, { expiresIn: 60 * 60 * 24 });
```

* @returns
*/
const crpytPassword = (val) => {
const salt = bcrypt.genSaltSync(10);
const hash = bcrypt.hashSync(val, salt);
return hash;
};
/**
* 解密验证
* @param {*} val 原始值
* @param {*} hash 加密后的值
* @returns
*/
const checkPassword = (val, hash) => {
return bcrypt.compareSync(val, hash);
};
```
