-
-### uniCloud.auth()
-
-获取`auth`的引用
-
-```js
-const auth = uniCloud.auth();
-```
-
-### auth.getUserInfo()
-
-获取用户信息
-
-```js
-const {
-  uid, //云开发用户唯一ID
-  customUserId //自定义登录传入的用户Id
-} = auth.getUserInfo()
-```
-
-### auth.getClientIP()
-
-获取客户端IP地址，上传并运行时返回空
-
-```js
-const IP = auth.getClientIP()
-```
-
-### auth.createTicket(String customUserId, Object createTicketOptions)@createticket
-
-此Api现在直接调用有问题，正在修复。可以先使用下面的方式调用
-
-```js
-const app = uniCloud.init({
-  spaceId: 'your-space-id',
-  credentials: require('./credentials.json')
-})
-
-const auth = app.auth();
-
-let customUserId = '123456';
-
-const ticket = auth.createTicket(customUserId, {
-  refresh: 10 * 60 * 1000 // 每十分钟刷新一次登录态， 默认为一小时
-});
-```
-
-
-开发者可以使用云函数创建登录凭证，提供给客户端进行登录操作。[详见](uniCloud/authentication.md#自定义登录)
-
-**createTicketOptions参数说明**
-
-|参数名	|类型		|必填	|默认值	|说明					|平台差异说明	|
-|:-			|:-			|:-		|:-			|:-						|:-						|
-|refresh|Number	|否		|3600000|token刷新间隔|-						|
-
-```js
-let customUserId = '123456';
-
-const ticket = auth.createTicket(customUserId, {
-  refresh: 10 * 60 * 1000 // 每十分钟刷新一次登录态， 默认为一小时
-});
-// 然后把 ticket 发送给客户端，由客户端调用auth.signInWithTicket()使用
-```
