定义
ts
interface ToolCallCollector字段结构
| 字段 | 类型 | 必需 | 说明 |
|---|---|---|---|
push | (part: ModelPart) => void | 必需 | Feed one part; text parts are ignored and cannot satisfy or break a call. |
calls | readonly AggregatedToolCall[] | 必需 | 只读。Calls started so far, including incomplete ones, in index order. |
complete | () => readonly AggregatedToolCall[] | 必需 | Finalize the calls. |

push
Feed one part; text parts are ignored and cannot satisfy or break a call.
ts
ToolCallCollector.push(part: ModelPart): voidFeed one part; text parts are ignored and cannot satisfy or break a call.
| 参数 | 类型 | 传递 | 说明 |
|---|---|---|---|
part | ModelPart | 必需 | — |
参数 part的可选结构: 选择其中一种结构,各分支的字段要求分别列出。
分支 1
string
分支 2
| 字段 | 类型 | 必需 | 说明 |
|---|---|---|---|
type | "function-call-delta" | 必需 | 见类型定义及调用场景。 |
index | number | 必需 | Index of the call within the response; deltas with the same index belong together. |
id | string | undefined | 可省略 | Provider call id, usually delivered once with the first delta. |
name | string | undefined | 可省略 | Function name, usually delivered once with the first delta. |
arguments | string | undefined | 可省略 | Raw JSON argument fragment; concatenating all fragments yields the full arguments. |
返回: void。
complete
Finalize the calls.
ts
ToolCallCollector.complete(): readonly AggregatedToolCall[]Finalize the calls.
无调用参数。
返回: readonly AggregatedToolCall[]。
使用示例
- 兼容 Provider 与自定义 Provider:Support 负责常见 Chat Completions HTTP/SSE 生命周期;App 可替换为自己的 ChatProvider。
- Support:推荐用法的聚合入口:Support 聚合推荐的构造、策略与同源配置生成;Core 运行不依赖这个命名空间。
真实服务端配置接入常见协议
入门 · Node.js
运行此例需要提供可用模型服务的连接配置。
ts
import { ModelRunner, Support } from '@jangts/agent-core';
const provider = new Support.CompatibleModelProvider({ config: {
baseUrl: process.env.MODEL_BASE_URL!, apiKey: process.env.MODEL_API_KEY!, model: process.env.MODEL_NAME!,
} });
const runner = new ModelRunner({ provider });
console.log((await runner.invoke('你好')).value);js
import { ModelRunner, Support } from '@jangts/agent-core';
const provider = new Support.CompatibleModelProvider({ config: {
baseUrl: process.env.MODEL_BASE_URL, apiKey: process.env.MODEL_API_KEY, model: process.env.MODEL_NAME,
} });
const runner = new ModelRunner({ provider });
console.log((await runner.invoke('你好')).value);直连工具线程的声明字段与 wire 映射
配置 · Node.js
只演示消息转换,无网络请求或工具执行。原始 tool_calls、tool_call_id 和宿主附加数据不透传。
ts
import { Support } from '@jangts/agent-core';
const messages: Support.ProviderMessage[] = [
{ role: 'user', content: '查询资料' },
{ role: 'assistant', content: '', toolCalls: [
{ id: 'call-1', name: 'lookup', arguments: '{"query":"资料"}' },
] },
{ role: 'tool', content: '{"found":true}', toolCallId: 'call-1' },
];
console.log(Support.chatCompletionMessages(messages));js
import { Support } from '@jangts/agent-core';
const messages = [
{ role: 'user', content: '查询资料' },
{ role: 'assistant', content: '', toolCalls: [
{ id: 'call-1', name: 'lookup', arguments: '{"query":"资料"}' },
] },
{ role: 'tool', content: '{"found":true}', toolCallId: 'call-1' },
];
console.log(Support.chatCompletionMessages(messages));
