Using files

Gemini API 支持单独上传媒体文件，无需在提示输入中包含媒体文件，这样一来，您的媒体文件就可以在多个请求和多个提示中重复使用。如需了解详情，请参阅使用媒体内容生成提示指南。

REST 资源：文件

资源：File

上传到 API 的文件。

字段
name string

不可变。标识符。File 资源名称。ID（不含“files/”前缀的名称）最多可包含 40 个字符，这些字符可以是小写字母数字字符或短划线 (-)。ID 不能以短划线开头或结尾。如果创建时名称为空，系统会生成一个唯一名称。示例：files/123-456

displayName string

可选。File 的人类可读显示名称。显示名称的长度不得超过 512 个字符（包括空格）。示例：“欢迎图片”

mimeType string

仅限输出。文件的 MIME 类型。

sizeBytes string (int64 format)

仅限输出。文件的大小（以字节为单位）。

createTime string (Timestamp format)

仅限输出。创建 File 时的时间戳。

采用 RFC 3339 标准，生成的输出将始终进行 Z 规范化（即转换为 UTC 零时区格式并在末尾附加 Z），并使用 0、3、6 或 9 个小数位。不进行“Z”归一化处理的偏差时间也是可以接受的。示例："2014-10-02T15:01:23Z"、"2014-10-02T15:01:23.045123456Z" 或 "2014-10-02T15:01:23+05:30"。

updateTime string (Timestamp format)

仅限输出。上次更新 File 时的时间戳。

采用 RFC 3339 标准，生成的输出将始终进行 Z 规范化（即转换为 UTC 零时区格式并在末尾附加 Z），并使用 0、3、6 或 9 个小数位。不进行“Z”归一化处理的偏差时间也是可以接受的。示例："2014-10-02T15:01:23Z"、"2014-10-02T15:01:23.045123456Z" 或 "2014-10-02T15:01:23+05:30"。

expirationTime string (Timestamp format)

仅限输出。相应 File 将被删除的时间戳。仅当 File 计划过期时才设置。

响应正文

对 media.upload 的响应。

如果成功，响应正文将包含结构如下的数据：

字段
file object (File)

所创建文件的元数据。

JSON 表示法 
{
  "file": {
    object (File)
  }
}

Status

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: ...,
      ...
    }
  ]
}
