TextSource

KIT · type · 类型合同

Text supplied to a text generator.

A function may be async; it receives the per-call context so a source can depend on the prompt or on the call index.

导入

TypeScript

import type { TextSource } from '@jangts/agent-core/mock';

JavaScript

/** @typedef {import('@jangts/agent-core/mock').TextSource} TextSource */

其他公开入口：@jangts/agent-core/mock。

定义

type TextSource = string | ((context: GenerationContext) => string | Promise<string>);

使用示例

• MockGPT Web：可信来源与本地摘要：从真实网页或可信 load 取得正文，再交给输入相关生成器。

可信 load 提供离线正文

入门 · Node.js

TypeScript

import { MockGPT, generators } from '@jangts/agent-core/mock';
import { sources, isPublicAddress } from '@jangts/agent-core/mock/web';
const source = sources.web({ url: 'https://example.com/article', async load(url, signal, maxBytes) {
  signal.throwIfAborted();
  const bytes = new TextEncoder().encode('服务维护完成。健康检查通过。');
  if (bytes.byteLength > maxBytes) throw new Error('来源超过预算');
  return { bytes, url: url.href, contentType: 'text/plain; charset=utf-8' };
} });
const mock = new MockGPT({ rules: [{ generator: generators.summary({ source }) }] });
console.log(await mock.generate({ model: 'demo', messages: [{ role: 'user', content: '概括正文' }] }));
console.log(isPublicAddress('127.0.0.1')); // false

JavaScript

import { MockGPT, generators } from '@jangts/agent-core/mock';
import { sources, isPublicAddress } from '@jangts/agent-core/mock/web';
const source = sources.web({ url: 'https://example.com/article', async load(url, signal, maxBytes) {
        signal.throwIfAborted();
        const bytes = new TextEncoder().encode('服务维护完成。健康检查通过。');
        if (bytes.byteLength > maxBytes)
            throw new Error('来源超过预算');
        return { bytes, url: url.href, contentType: 'text/plain; charset=utf-8' };
    } });
const mock = new MockGPT({ rules: [{ generator: generators.summary({ source }) }] });
console.log(await mock.generate({ model: 'demo', messages: [{ role: 'user', content: '概括正文' }] }));
console.log(isPublicAddress('127.0.0.1')); // false

显式开启网页来源与失败替代文本

配置 · Node.js

TypeScript

import { MockGPT, generators } from '@jangts/agent-core/mock';
import { sources } from '@jangts/agent-core/mock/web';
const mock = new MockGPT({ rules: [{ generator: generators.summary({ source: sources.web({
  url: 'https://example.com/article', timeoutMs: 5000,
  fallback: '网页不可读取，请提供正文。',
}) }) }] });
console.log(await mock.generate({ model: 'demo', messages: [{ role: 'user', content: '总结文章' }] }));
console.log(mock.records); // 检查 sourceFallback/sourceError，不把替代文本当原文

JavaScript

import { MockGPT, generators } from '@jangts/agent-core/mock';
import { sources } from '@jangts/agent-core/mock/web';
const mock = new MockGPT({ rules: [{ generator: generators.summary({ source: sources.web({
                    url: 'https://example.com/article', timeoutMs: 5000,
                    fallback: '网页不可读取，请提供正文。',
                }) }) }] });
console.log(await mock.generate({ model: 'demo', messages: [{ role: 'user', content: '总结文章' }] }));
console.log(mock.records); // 检查 sourceFallback/sourceError，不把替代文本当原文
