Hi @刘友缘 ,
PersonalizationData in Search Rest API passed like this:
GET http:// \<server\>/_api/search/query?querytext='sharepoint'&personalizationdata=' \<GUID\>'
The user guid can be got from this endpoint:
http://siteurl/_api/web/SiteUserInfoList/Items/
Please note, the user guid is different for different site collection, so please use the site url which is the same as the site url used in Search Rest API.
