添加文件

上传文件并将其挂载到容器中以供读取和处理。

您可以通过 Files API 上传文件并将其挂载到会话容器中来为代理提供文件。

Note

所有托管代理 API 请求都需要 managed-agents-2026-04-01 beta 头。SDK 会自动设置该 beta 头。

上传文件

首先，使用 Files API 上传文件：

file=$(curl --fail-with-body -sS "${auth[@]}" \
  "${base_url}/files" \
  -F file=@data.csv)
file_id=$(jq -er '.id' <<<"${file}")
printf 'File ID: %s\n' "${file_id}"

FILE_ID=$(ant beta:files upload \
  --file data.csv \
  --transform id --raw-output)

file = client.beta.files.upload(file=Path("data.csv"))
print(f"File ID: {file.id}")

const file = await client.beta.files.upload({
  file: await toFile(readFile("data.csv"), "data.csv", { type: "text/csv" }),
});
console.log(`File ID: ${file.id}`);

await using var stream = File.OpenRead(csvPath);
var file = await client.Beta.Files.Upload(new() { File = stream });
Console.WriteLine({{CONTENT}}quot;File ID: {file.ID}");

csvFile, err := os.Open("data.csv")
if err != nil {
	panic(err)
}
defer csvFile.Close()

file, err := client.Beta.Files.Upload(ctx, anthropic.BetaFileUploadParams{
	File: csvFile,
})
if err != nil {
	panic(err)
}
fmt.Printf("File ID: %s\n", file.ID)

var file = client.beta().files().upload(
    FileUploadParams.builder().file(dataCsv).build()
);
IO.println("File ID: " + file.id());

$file = $client->beta->files->upload(
    FileParam::fromResource(fopen($csvPath, 'r'), filename: 'data.csv', contentType: 'text/csv'),
);
echo "File ID: {$file->id}\n";

file = client.beta.files.upload(file: Pathname(csv_path))
puts "File ID: #{file.id}"

在会话中挂载文件

通过在创建会话时将上传的文件添加到 resources 数组中来将其挂载到容器中：

Tip

mount_path 是可选的，但请确保上传的文件具有描述性名称，以便代理知道它在寻找什么。

session=$(
  jq -n \
    --arg agent_id "${agent_id}" \
    --arg environment_id "${environment_id}" \
    --arg file_id "${file_id}" \
    '{
      agent: $agent_id,
      environment_id: $environment_id,
      resources: [
        {
          type: "file",
          file_id: $file_id,
          mount_path: "/workspace/data.csv"
        }
      ]
    }' | curl --fail-with-body -sS "${auth[@]}" "${base_url}/sessions" --json @-
)
session_id=$(jq -er '.id' <<<"${session}")

SESSION_ID=$(ant beta:sessions create \
  --agent "$AGENT_ID" \
  --environment-id "$ENVIRONMENT_ID" \
  --transform id --raw-output <<EOF
resources:
  - type: file
    file_id: $FILE_ID
    mount_path: /workspace/data.csv
EOF
)

session = client.beta.sessions.create(
    agent=agent.id,
    environment_id=environment.id,
    resources=[
        {
            "type": "file",
            "file_id": file.id,
            "mount_path": "/workspace/data.csv",
        },
    ],
)

const session = await client.beta.sessions.create({
  agent: agent.id,
  environment_id: environment.id,
  resources: [
    {
      type: "file",
      file_id: file.id,
      mount_path: "/workspace/data.csv",
    },
  ],
});

var session = await client.Beta.Sessions.Create(new()
{
    Agent = agent.ID,
    EnvironmentID = environment.ID,
    Resources =
    [
        new BetaManagedAgentsFileResourceParams
        {
            Type = "file",
            FileID = file.ID,
            MountPath = "/workspace/data.csv",
        },
    ],
});

session, err := client.Beta.Sessions.New(ctx, anthropic.BetaSessionNewParams{
	Agent: anthropic.BetaSessionNewParamsAgentUnion{
		OfString: anthropic.String(agent.ID),
	},
	EnvironmentID: environment.ID,
	Resources: []anthropic.BetaSessionNewParamsResourceUnion{{
		OfFile: &anthropic.BetaManagedAgentsFileResourceParams{
			Type:      anthropic.BetaManagedAgentsFileResourceParamsTypeFile,
			FileID:    file.ID,
			MountPath: anthropic.String("/workspace/data.csv"),
		},
	}},
})
if err != nil {
	panic(err)
}

var session = client.beta().sessions().create(
    SessionCreateParams.builder()
        .agent(agent.id())
        .environmentId(environment.id())
        .addResource(
            BetaManagedAgentsFileResourceParams.builder()
                .type(BetaManagedAgentsFileResourceParams.Type.FILE)
                .fileId(file.id())
                .mountPath("/workspace/data.csv")
                .build()
        )
        .build()
);

$session = $client->beta->sessions->create(
    agent: $agent->id,
    environmentID: $environment->id,
    resources: [
        BetaManagedAgentsFileResourceParams::with(
            type: 'file',
            fileID: $file->id,
            mountPath: '/workspace/data.csv',
        ),
    ],
);

session = client.beta.sessions.create(
  agent: agent.id,
  environment_id: environment.id,
  resources: [
    {
      type: "file",
      file_id: file.id,
      mount_path: "/workspace/data.csv"
    }
  ]
)

将创建一个新的 file_id，引用会话中文件的实例。这些副本不计入您的存储限制。

多个文件

通过向 resources 数组添加条目来挂载多个文件：

{
  "resources": [
    { "type": "file", "file_id": "file_abc123", "mount_path": "/workspace/data.csv" },
    { "type": "file", "file_id": "file_def456", "mount_path": "/workspace/config.json" },
    { "type": "file", "file_id": "file_ghi789", "mount_path": "/workspace/src/main.py" }
  ]
}

resources:
  - type: file
    file_id: file_abc123
    mount_path: /workspace/data.csv
  - type: file
    file_id: file_def456
    mount_path: /workspace/config.json
  - type: file
    file_id: file_ghi789
    mount_path: /workspace/src/main.py

resources = [
    {"type": "file", "file_id": "file_abc123", "mount_path": "/workspace/data.csv"},
    {"type": "file", "file_id": "file_def456", "mount_path": "/workspace/config.json"},
    {"type": "file", "file_id": "file_ghi789", "mount_path": "/workspace/src/main.py"},
]

const _ = {
  resources: [
    { type: "file", file_id: "file_abc123", mount_path: "/workspace/data.csv" },
    { type: "file", file_id: "file_def456", mount_path: "/workspace/config.json" },
    { type: "file", file_id: "file_ghi789", mount_path: "/workspace/src/main.py" }
  ]
};

var resources = new[]
{
    new BetaManagedAgentsFileResourceParams { Type = BetaManagedAgentsFileResourceParamsType.File, FileID = "file_abc123", MountPath = "/workspace/data.csv" },
    new BetaManagedAgentsFileResourceParams { Type = BetaManagedAgentsFileResourceParamsType.File, FileID = "file_def456", MountPath = "/workspace/config.json" },
    new BetaManagedAgentsFileResourceParams { Type = BetaManagedAgentsFileResourceParamsType.File, FileID = "file_ghi789", MountPath = "/workspace/src/main.py" },
};

resources := []anthropic.BetaSessionNewParamsResourceUnion{
	{OfFile: &anthropic.BetaManagedAgentsFileResourceParams{Type: "file", FileID: "file_abc123", MountPath: anthropic.String("/workspace/data.csv")}},
	{OfFile: &anthropic.BetaManagedAgentsFileResourceParams{Type: "file", FileID: "file_def456", MountPath: anthropic.String("/workspace/config.json")}},
	{OfFile: &anthropic.BetaManagedAgentsFileResourceParams{Type: "file", FileID: "file_ghi789", MountPath: anthropic.String("/workspace/src/main.py")}},
}
_ = resources

var resources = List.of(
    BetaManagedAgentsFileResourceParams.builder()
        .type(BetaManagedAgentsFileResourceParams.Type.FILE).fileId("file_abc123").mountPath("/workspace/data.csv").build(),
    BetaManagedAgentsFileResourceParams.builder()
        .type(BetaManagedAgentsFileResourceParams.Type.FILE).fileId("file_def456").mountPath("/workspace/config.json").build(),
    BetaManagedAgentsFileResourceParams.builder()
        .type(BetaManagedAgentsFileResourceParams.Type.FILE).fileId("file_ghi789").mountPath("/workspace/src/main.py").build()
);

$resources = [
    ['type' => 'file', 'file_id' => 'file_abc123', 'mount_path' => '/workspace/data.csv'],
    ['type' => 'file', 'file_id' => 'file_def456', 'mount_path' => '/workspace/config.json'],
    ['type' => 'file', 'file_id' => 'file_ghi789', 'mount_path' => '/workspace/src/main.py'],
];

resources = [
  {type: "file", file_id: "file_abc123", mount_path: "/workspace/data.csv"},
  {type: "file", file_id: "file_def456", mount_path: "/workspace/config.json"},
  {type: "file", file_id: "file_ghi789", mount_path: "/workspace/src/main.py"}
]

每个会话最多支持 100 个文件。

在运行中的会话上管理文件

您可以在创建会话后使用会话资源 API 添加或删除文件。每个资源在添加时（或通过 resources.list）返回一个 id，用于删除操作。

resource=$(
  jq -n --arg file_id "${file_id}" '{type: "file", file_id: $file_id}' \
    | curl --fail-with-body -sS "${auth[@]}" \
        "${base_url}/sessions/${session_id}/resources" --json @-
)
resource_id=$(jq -er '.id' <<<"${resource}")
printf '%s\n' "${resource_id}"  # "sesrsc_01ABC..."

RESOURCE_ID=$(ant beta:sessions:resources add \
  --session-id "$SESSION_ID" \
  --type file \
  --file-id "$FILE_ID" \
  --transform id --raw-output)

resource = client.beta.sessions.resources.add(
    session.id,
    type="file",
    file_id=file.id,
)
print(resource.id)  # "sesrsc_01ABC..."

const resource = await client.beta.sessions.resources.add(session.id, {
  type: "file",
  file_id: file.id,
});
console.log(resource.id); // "sesrsc_01ABC..."

var resource = await client.Beta.Sessions.Resources.Add(session.ID, new()
{
    Type = "file",
    FileID = file.ID,
});
Console.WriteLine(resource.ID);  // "sesrsc_01ABC..."

resource, err := client.Beta.Sessions.Resources.Add(ctx, session.ID, anthropic.BetaSessionResourceAddParams{
	BetaManagedAgentsFileResourceParams: anthropic.BetaManagedAgentsFileResourceParams{
		Type:   anthropic.BetaManagedAgentsFileResourceParamsTypeFile,
		FileID: file.ID,
	},
})
if err != nil {
	panic(err)
}
fmt.Println(resource.ID) // "sesrsc_01ABC..."

var resource = client.beta().sessions().resources().add(
    session.id(),
    ResourceAddParams.builder()
        .betaManagedAgentsFileResourceParams(
            BetaManagedAgentsFileResourceParams.builder()
                .type(BetaManagedAgentsFileResourceParams.Type.FILE)
                .fileId(file.id())
                .build()
        )
        .build()
);
IO.println(resource.id()); // "sesrsc_01ABC..."

$resource = $client->beta->sessions->resources->add(
    $session->id,
    type: 'file',
    fileID: $file->id,
);
echo "{$resource->id}\n";  // "sesrsc_01ABC..."

resource = client.beta.sessions.resources.add(
  session.id,
  type: "file",
  file_id: file.id
)
puts resource.id # "sesrsc_01ABC..."

使用 resources.list 列出会话上的所有资源。要删除文件，请使用资源 ID 调用 resources.delete：

curl --fail-with-body -sS "${auth[@]}" \
  "${base_url}/sessions/${session_id}/resources" \
  | jq -r '.data[] | "\(.id) \(.type)"'

curl --fail-with-body -sS "${auth[@]}" -X DELETE \
  "${base_url}/sessions/${session_id}/resources/${resource_id}" >/dev/null

ant beta:sessions:resources list --session-id "$SESSION_ID"

ant beta:sessions:resources delete \
  --session-id "$SESSION_ID" \
  --resource-id "$RESOURCE_ID"

listed = client.beta.sessions.resources.list(session.id)
for entry in listed.data:
    print(entry.id, entry.type)

client.beta.sessions.resources.delete(resource.id, session_id=session.id)

const listed = await client.beta.sessions.resources.list(session.id);
for (const entry of listed.data) {
  console.log(entry.id, entry.type);
}

await client.beta.sessions.resources.delete(resource.id, {
  session_id: session.id,
});

var listed = await client.Beta.Sessions.Resources.List(session.ID);
await foreach (var entry in listed.Paginate())
{
    var type = entry.Match<string>(repo => repo.Type, fileRes => fileRes.Type, memoryStore => memoryStore.Type);
    Console.WriteLine({{CONTENT}}quot;{entry.ID} {type}");
}

await client.Beta.Sessions.Resources.Delete(resource.ID, new() { SessionID = session.ID });

listed, err := client.Beta.Sessions.Resources.List(ctx, session.ID, anthropic.BetaSessionResourceListParams{})
if err != nil {
	panic(err)
}
for _, entry := range listed.Data {
	fmt.Println(entry.ID, entry.Type)
}

if _, err := client.Beta.Sessions.Resources.Delete(ctx, resource.ID, anthropic.BetaSessionResourceDeleteParams{
	SessionID: session.ID,
}); err != nil {
	panic(err)
}

var listed = client.beta().sessions().resources().list(session.id());
for (var entry : listed.data()) {
    if (entry.isFile()) {
        var fileResource = entry.asFile();
        IO.println(fileResource.id() + " " + fileResource.type());
    } else if (entry.isGitHubRepository()) {
        var repoResource = entry.asGitHubRepository();
        IO.println(repoResource.id() + " " + repoResource.type());
    }
}

client.beta().sessions().resources().delete(
    resource.id(),
    ResourceDeleteParams.builder().sessionId(session.id()).build()
);

$listed = $client->beta->sessions->resources->list($session->id);
foreach ($listed->data as $entry) {
    echo "{$entry->id} {$entry->type}\n";
}

$client->beta->sessions->resources->delete($resource->id, sessionID: $session->id);

listed = client.beta.sessions.resources.list(session.id)
listed.data.each { puts "#{it.id} #{it.type}" }

client.beta.sessions.resources.delete(resource.id, session_id: session.id)

列出和下载会话文件

使用 Files API 列出会话范围内的文件并下载它们。

支持的文件类型

代理可以处理任何文件类型，包括：

  • 源代码（.py、.js、.ts、.go、.rs 等）
  • 数据文件（.csv、.json、.xml、.yaml）
  • 文档（.txt、.md）
  • 压缩包（.zip、.tar.gz）- 代理可以使用 bash 解压这些文件
  • 二进制文件 - 代理可以使用适当的工具处理这些文件

文件路径

Note

挂载在容器中的文件是只读副本。代理可以读取它们但不能修改原始上传的文件。要处理修改后的版本，代理在容器内写入新路径。

  • 文件挂载在您指定的精确路径
  • 父目录会自动创建
  • 路径应该是绝对路径（以 / 开头）
