所以问题是我不知道新创建的站点的id是否正确，以及是否可以在站点成功创建后立即使用它。如何区分正确的行为？
使用POST 请求创建通信站点后，使用/_api/sitepages/communicationsite/create
正文：
{
{"request", {
{"__metadata", {
{"type", "SP.Publishing.CommunicationSiteCreationRequest"}
}},
{"Url", siteInfo.url},
{"Title", siteInfo.title},
{"SiteDesignId", siteInfo.designId},
{"Classification", ""}
}}
}
响应返回新创建站点的 id。
但是，如果我想从GET /sites/{hostname}:/{server-relative-path}请求中获取该站点 id，
我将面临这样一个奇怪的行为（每次 id 随机更改！！！）：在创建新站点后，我已经执行了上述请求的 11 次. 这是结果
