Provide dynamic roles based authorisation. Use [koa-roles](https://github.com/koajs/koa-roles).
## Install
```bash
$ npm i egg-userrole --save
```
## Usage
```javascript
// {app_root}/config/plugin.js
exports.userrole = {
package: 'egg-userrole',
};
```
> Recommend to use along with custom `userservice` plugin (which provide `ctx.user`).
>
> see [`egg-userservice`](https://github.com/eggjs/egg-userservice) for more info.
### Build-in
`Roles` build-in `failureHandler`:
```javascript
function failureHandler(ctx, action) {
const message = 'Forbidden, required role: ' + action;
if (ctx.acceptJSON) {
ctx.body = {
message: message,
stat: 'deny',
};
} else {
ctx.status = 403;
ctx.body = message;
}
};
```
Build-in `user` role define:
```javascript
app.role.use('user', ctx => !!ctx.user);
```
### How to custom `failureHandler`
Define `app.role.failureHandler(action)` method in `config/role.js`
- `app/extend/context.js`
```javascript
// {app_root}/config/role.js or {framework_root}/config/role.js
module.exports = app => {
app.role.failureHandler = function(ctx, action) {
if (ctx.acceptJSON) {
ctx.body = { target: loginURL, stat: 'deny' };
} else {
ctx.realStatus = 200;
ctx.redirect(loginURL);
}
};
}
```
### How to custom role
```javascript
// {app_root}/config/role.js or {framework_root}/config/role.js
module.exports = function(app) {
app.role.use('admin', ctx => {
return ctx.user && ctx.user.isAdmin;
});
app.role.use('can write', async ctx => {
const post = await ctx.service.post.fetch(ctx.request.body.id);
return ctx.user.name === post.author;
});
};
```
