有没有办法保留或者丢弃引用链接数据？

By default, when users arrive on a page running Journeys via a Branch link and make_new_link is not set to true, then any interaction with the Journey (click/install/re-open) will be attributed to the referring Branch link, rather than to the Journey. If make_new_link is set to true, the same events will be attributed to the Journey, instead.

即便用户没有直接从这些链接进行安装，这也可以帮助您收集有关推荐链接如何有助于应用增长/参与度的数据。例如，如果用户点击了 Facebook 上的 Branch Link 并登陆到您的网站上，还从 Journey (站到端引流)进行了安装，您便可以将此安装归因于 Facebook 上的链接。如果原始链接也配置为您的应用中的深度链接，则该深度链接也将予以保留。

Branch will pass the referring link into Journeys by default. In order to discard referring link data, include the make_new_link flag, with a value of true, into the options during initialization:

branch.init( 'BRANCH_KEY',
    {
        'make_new_link' : true
    }
);
