Using files

Gemini API 支持将媒体文件与提示输入分开上传,这样您就可以在多个请求和多个提示中重复使用媒体。如需了解详情,请参阅使用媒体提示指南。

方法:media.upload

创建 File

端点

  • 上传 URI,用于媒体上传请求:
发布 https://generativelanguage.googleapis.com/upload/v1beta/files
  • 元数据 URI,适用于仅含元数据的请求:
发布 https://generativelanguage.googleapis.com/v1beta/files

请求正文

请求正文中包含结构如下的数据:

<ph type="x-smartling-placeholder">
</ph> 田野
file object (File)

可选。要创建的文件的元数据。

  "sizeBytes": string,
  "createTime": string,
  "updateTime": string,
  "expirationTime": string,
  "sha256Hash": string,
  "uri": string,
  "state": enum (State),
  "error": {
    object (Status)
  },

  // Union field metadata can be only one of the following:
  "videoMetadata": {
    object (VideoMetadata)
  }
  // End of list of possible types for union field metadata.

VideoMetadata

视频 File 的元数据。

田野
videoDuration string (Duration format)

视频的时长。

该时长以秒为单位,最多包含九个小数位,以“s”结尾。示例:"3.5s"

JSON 表示法

文件生命周期的状态。

枚举
STATE_UNSPECIFIED 默认值。如果省略状态,则使用此值。
PROCESSING 文件正在处理中,尚无法用于推理。
ACTIVE 文件已处理完毕,可用于推理。
FAILED 文件处理失败。

状态

Status 类型定义了适用于不同编程环境(包括 REST API 和 RPC API)的逻辑错误模型。此类型供 gRPC 使用。每条 Status 消息包含三部分数据:错误代码、错误消息和错误详细信息。

如需详细了解该错误模型及其使用方法,请参阅 API 设计指南

字段
code integer

状态代码,应为 google.rpc.Code 的枚举值。

message string

面向开发者的错误消息(应采用英语)。任何向用户显示的错误消息都应进行本地化并通过 google.rpc.Status.details 字段发送,或者由客户端进行本地化。

details[] object

包含错误详细信息的消息列表。有一组通用的消息类型可供 API 使用。

可以包含任意类型字段的对象。附加字段 "@type" 包含用于标示相应类型的 URI。示例:{ "id": 1234, "@type": "types.example.com/standard/id" }

JSON 表示法
{
  "code": integer,
  "message": string,
  "details": [
    {
      "@type": string,
      field1: ...,
      ...
    }
  ]
