CredentialsContainer - Web API 接口参考

这是一个实验中的功能
此功能某些浏览器尚在开发中，请参考浏览器兼容性表格以得到在不同浏览器中适合使用的前缀。由于该功能对应的标准文档可能被重新修订，所以在未来版本的浏览器中该功能的语法和行为可能随之改变。

Credential Management API 的 CredentialsContainer 接口提供了请求 credentials 和通知用户代理（当成功登陆或登出事件发生时）的方法。可通过 Navigator.credentials 获得该接口。

属性

None.

事件

None.

返回一个带有处理值 Credential（若它能够使用提供的选项创建的话）的 Promise ，或返回 null（若不能创建 Credential）。在特殊情况下，返回的 Promise 对象可能 reject。

方法

CredentialsContainer.create(): Returns a Promise that resolves with a new Credential instance based on the provided options, or null of no Credential object can be created.
CredentialsContainer.get(): Returns a Promise that resolves with the Credential instance that matches the provided parameters.
CredentialsContainer.preventSilentAccess(): Sets a flag that specifies whether automatic log in is allowed for future visits to the current origin, then returns an empty Promise. For example, you might call this, after a user signs out of a website to ensure that he/she isn't automatically signed in on the next site visit. Earlier versions of the spec called this method requireUserMediation(). See Browser compatibility for support details.
CredentialsContainer.store(): Stores a set of credentials for a user, inside a provided Credential instance and returns that instance in a Promise.
