处理数据

插入、读取、更新和删除文档。

开始之前: 本指南使用 快速开始 留下的 customers 集合(包含 Ada 和 Grace)及其环境变量。它会添加两个标记为 "trial": true 的临时客户,并在最后删除它们,因此 customers 会恢复原样。

插入文档

插入使用 JSON Lines(JSONL):每行一个 JSON 对象。一个请求可以包含一个文档,也可以包含数百万个。

响应(201 Created)返回已保存的文档,其中已应用集合的默认值:

1{"id":"linus","name":"Linus Torvalds","plan":"free","country":"FI","mrr":0,"trial":true}
2{"id":"barbara","name":"Barbara Liskov","plan":"team","country":"US","mrr":300,"trial":true}

JSON 数组不是 JSONL。这个请求体会以 400 Bad Request 被拒绝,消息为 document must be a JSON object:

1[{"id":"linus"},{"id":"barbara"}]

同样的两个文档,使用 JSONL:

1{"id":"linus"}
2{"id":"barbara"}

注意:

  • 没有 id 的文档会从集合的 默认值 获得一个(除非你修改,否则是随机 UUID)。
  • InceptionDB 不检查 id 是否唯一:用同一个 id 插入两次会保存两个文档。要避免这种情况,请在 id 上创建 map 索引。之后重复的 id 会返回 409 Conflict,按 id 读取也会立即完成。
  • 文档按顺序保存,插入会在第一个被拒绝的文档处停止。之前的文档仍会保存。
  • 要加载文件,使用 --data-binary @customers.jsonl。-d 会去掉换行符。
  • 每个文档必须是没有重复字段名的 JSON 对象,否则返回 400 Bad Request。
  • 如果 唯一索引 中已存在该值,返回 409 Conflict。
  • 向不存在的集合插入会创建该集合。请检查 URL 中的集合名称。

要一次读取多个文档,请使用 查询。

更新文档

patch 只修改你发送的字段(JSON merge patch):新字段会被添加,已有字段会被替换,null 会删除字段。
