使用 Python 自动化演示文稿生成：2Slides API 教程

Python 是自动化、数据管道和 AI 工作流的首选语言。本教程将向您展示如何使用 Python 调用 2Slides REST API 自动生成演示文稿 — 从简单的单页幻灯片到复杂的自动化流程。

前提条件

pip install requests python-dotenv

创建一个

文件：

TWOSLIDES_API_KEY=sk-2slides-your-api-key

快速入门：生成您的第一份幻灯片

import os
import time
import requests
from dotenv import load_dotenv

load_dotenv()

API_KEY = os.getenv('TWOSLIDES_API_KEY')
BASE_URL = 'https://2slides.com/api/v1'
HEADERS = {
    'Authorization': f'Bearer {API_KEY}',
    'Content-Type': 'application/json'
}

def generate_slides(topic, theme_id=None, mode='async'):
    """根据文本主题生成演示文稿。"""
    payload = {
        'userInput': topic,
        'mode': mode,
        'responseLanguage': 'en',
        'resolution': '2K',
    }
    if theme_id:
        payload['themeId'] = theme_id

    response = requests.post(
        f'{BASE_URL}/slides/generate',
        headers=HEADERS,
        json=payload
    )
    response.raise_for_status()
    return response.json()

def wait_for_job(job_id, timeout=300, interval=3):
    """轮询直到任务完成。"""
    start = time.time()
    while time.time() - start < timeout:
        response = requests.get(
            f'{BASE_URL}/jobs/{job_id}',
            headers=HEADERS
        )
        data = response.json()
        status = data.get('status')
        print(f'  任务 {job_id}: {status}')

        if status == 'success':
            return data
        if status == 'failed':
            raise Exception(f'任务失败: {data}')

        time.sleep(interval)
    raise TimeoutError(f'任务 {job_id} 在 {timeout} 秒后超时')

# 生成演示文稿
job = generate_slides('Top 10 AI Trends for 2026')
print(f'任务 ID: {job["jobId"]}')

result = wait_for_job(job['jobId'])
print(f'下载链接: {result["downloadUrl"]}')

将文档转换为幻灯片

def convert_file_to_slides(file_url, prompt='', theme_id=None):
    """将 PDF、DOCX、XLSX 或其他文件转换为幻灯片。"""
    payload = {
        'fileUrl': file_url,
        'userInput': prompt,
        'mode': 'async'
    }
    if theme_id:
        payload['themeId'] = theme_id

    response = requests.post(
        f'{BASE_URL}/slides/create-pdf-slides',
        headers=HEADERS,
        json=payload
    )
    response.raise_for_status()
    job = response.json()
    return wait_for_job(job['jobId'])

# 转换季度报告 PDF
result = convert_file_to_slides(
    file_url='https://your-storage.com/q1-report.pdf',
    prompt='Executive summary for the board, 10 slides max'
)
print(f'下载链接: {result["downloadUrl"]}')

设计风格匹配的幻灯片（以此为范例创建）

def create_like_this(topic, reference_image_url, resolution='2K'):
    """生成与参考设计匹配的幻灯片。"""
    payload = {
        'userInput': topic,
        'designStyle': {
            'global': {
                'referenceImageUrl': reference_image_url
            }
        },
        'resolution': resolution,
        'mode': 'async'
    }

    response = requests.post(
        f'{BASE_URL}/slides/create-like-this',
        headers=HEADERS,
        json=payload
    )
    response.raise_for_status()
    job = response.json()
    return wait_for_job(job['jobId'])

# 匹配您的品牌模板
result = create_like_this(
    topic='Monthly Team Update — March 2026',
    reference_image_url='https://your-brand.com/slide-template.png'
)

添加语音旁白

def add_narration(job_id, mode='single', voice='Charon', content_mode='concise'):
    """为现有幻灯片添加 AI 语音旁白。"""
    payload = {
        'jobId': job_id,
        'mode': mode,
        'voice': voice,
        'contentMode': content_mode
    }

    response = requests.post(
        f'{BASE_URL}/slides/generate-narration',
        headers=HEADERS,
        json=payload
    )
    response.raise_for_status()
    return response.json()

def download_with_audio(job_id):
    """下载包含语音音频文件的幻灯片。"""
    response = requests.post(
        f'{BASE_URL}/slides/download-slides-pages-voices',
        headers=HEADERS,
        json={'jobId': job_id}
    )
    response.raise_for_status()
    return response.json()

浏览主题

def search_themes(query=''):
    """搜索可用的幻灯片主题。"""
    params = {'query': query} if query else {}
    response = requests.get(
        f'{BASE_URL}/themes',
        headers=HEADERS,
        params=params
    )
    response.raise_for_status()
    return response.json()

themes = search_themes('corporate')
for theme in themes.get('themes', []):
    print(f"{theme['id']}: {theme['name']}")

生产级管道示例

"""

"""

import json
from datetime import datetime

def weekly_report_pipeline():
    print(f'正在生成周报: {datetime.now().isoformat()}')

    # 1. 生成幻灯片
    job = generate_slides(
        topic='''Weekly Engineering Update — Week of March 23, 2026:
        - Deployed v2.4 to production (99.9% uptime)

        theme_id='corporate-standard-id'
    )

    result = wait_for_job(job['jobId'])
    print(f'幻灯片已就绪: {result["downloadUrl"]}')

    # 2. 添加旁白
    add_narration(job['jobId'], mode='single', voice='Kore')
    print('旁白已添加')

    # 3. 下载打包文件
    package = download_with_audio(job['jobId'])
    print(f'完整打包文件: {json.dumps(package, indent=2)}')

    return result['downloadUrl']

if __name__ == '__main__':
    url = weekly_report_pipeline()
    print(f'\n报告 URL: {url}')

错误处理最佳实践

from requests.exceptions import HTTPError, Timeout, ConnectionError

def safe_generate(topic, retries=3):
    """使用重试逻辑生成幻灯片。"""
    for attempt in range(retries):
        try:
            job = generate_slides(topic)
            return wait_for_job(job['jobId'])
        except HTTPError as e:
            if e.response.status_code == 429:
                wait = 2 ** attempt * 5  # 指数退避
                print(f'达到速率限制。等待 {wait} 秒...')
                time.sleep(wait)
            elif e.response.status_code == 402:
                raise Exception('积分不足')
            else:
                raise
        except (Timeout, ConnectionError) as e:
            print(f'网络错误 (尝试 {attempt + 1} 次): {e}')
            time.sleep(5)
    raise Exception(f'在 {retries} 次重试后失败')

常见问题

需要哪个 Python 版本？

Python 3.7+，以支持 f-string 和

兼容性。

我可以使用异步 Python (asyncio/aiohttp) 吗？

是的 — 将

替换为 以进行异步 HTTP 调用。轮询模式的工作方式相同。

如何处理大型批量任务？

使用 asyncio 并发运行多个生成任务，同时遵守速率限制（每分钟 60 次请求）。
