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。

}

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

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: ...,
      ...
