## 📖 详细文档
### 1. 文本提取 (PDFExtractor)
```python
from src.pdf_intelligence_suite import PDFExtractor
extractor = PDFExtractor()
# 提取全部文本
text = extractor.extract_text("document.pdf")
# 提取指定页面
text = extractor.extract_text("document.pdf", pages=[0, 1, 2])
# 提取带位置信息的文本
elements = extractor.extract_with_layout("document.pdf")
for elem in elements:
print(f"Text: {elem.text}, Page: {elem.page}, Position: {elem.bbox}")
# 按坐标区域提取
text = extractor.extract_by_bbox("document.pdf", page=0, bbox=(100, 100, 300, 200))
```
### 2. 表格识别 (TableExtractor)
```python
from src.pdf_intelligence_suite import TableExtractor
# 提取所有表格
tables = TableExtractor.extract_tables("report.pdf")
# 提取指定页面的表格
tables = TableExtractor.extract_tables("report.pdf", pages=[1, 2])
# 指定提取方法
# 'lattice': 用于有清晰边框的表格
# 'stream': 用于无边框或空格分隔的表格
tables = TableExtractor.extract_tables("report.pdf", method='lattice')
# 导出格式
for i, table in enumerate(tables):
# 转为DataFrame
df = table.df
# 保存为Excel
table.to_excel(f"table_{i}.xlsx")
# 保存为CSV
table.to_csv(f"table_{i}.csv")
```
### 3. OCR文字识别 (OCRProcessor)
```python
from src.pdf_intelligence_suite import OCRProcessor
# 初始化（指定语言）
ocr = OCRProcessor(languages=['chi_sim', 'eng']) # 中文简体+英文
# 识别整个PDF
text = ocr.process_pdf("scanned.pdf")
# 识别指定页面
text = ocr.process_pdf("scanned.pdf", pages=[0, 1])
# 识别单张图片
from PIL import Image
img = Image.open("page.png")
text = ocr.process_image(img)
# 获取详细结果（包含位置信息）
results = ocr.process_pdf_with_data("scanned.pdf")
for item in results:
print(f"Text: {item['text']}, Confidence: {item['confidence']}")
```
### 4. 格式转换 (PDFConverter)
```python
from src.pdf_intelligence_suite import PDFConverter
converter = PDFConverter()
# PDF转Word
converter.to_word("input.pdf", "output.docx")
# PDF转Excel
converter.to_excel("input.pdf", "output.xlsx")
# PDF转图片（每页一张）
converter.to_images("input.pdf", output_dir="./images", fmt="png")
# PDF转文本
converter.to_text("input.pdf", "output.txt")
# PDF转HTML
converter.to_html("input.pdf", "output.html")
```
### 5. 页面操作 (PDFManipulator)
```python
from src.pdf_intelligence_suite import PDFManipulator
manip = PDFManipulator()
# 合并多个PDF
manip.merge(["file1.pdf", "file2.pdf", "file3.pdf"], "merged.pdf")
# 拆分PDF
manip.split("document.pdf", [3, 5], "part_{}.pdf") # 在第3页和第5页后拆分
# 旋转页面
manip.rotate("document.pdf", [0, 1], 90, "rotated.pdf") # 第1、2页顺时针旋转90度
# 删除页面
manip.remove_pages("document.pdf", [2, 3], "removed.pdf")
# 提取页面
manip.extract_pages("document.pdf", [0, 2, 4], "extracted.pdf")
# 插入页面
manip.insert_pages("base.pdf", "insert.pdf", position=2, output="result.pdf")
```
### 6. 安全处理 (PDFSecurity)
```python
from src.pdf_intelligence_suite import PDFSecurity
security = PDFSecurity()
# 加密PDF
security.encrypt("input.pdf", "encrypted.pdf", password="secret123")
# 解密PDF
security.decrypt("encrypted.pdf", "decrypted.pdf", password="secret123")
# 添加水印
security.add_watermark(
"input.pdf",
"watermarked.pdf",
text="CONFIDENTIAL",
opacity=0.3,
angle=45
)
# 添加图片水印
security.add_image_watermark(
"input.pdf",
"watermarked.pdf",
image_path="logo.png",
position="center"
)
```

# macOS
brew install tesseract-lang
```
### Q: 表格识别不准确？
A: 尝试切换识别方法：
```python
# 对于有边框的表格
tables = TableExtractor.extract_tables("report.pdf", method='lattice')
# 对于无边框表格
tables = TableExtractor.extract_tables("report.pdf", method='stream')
```
### Q: 转换后的Word格式错乱？
A: 复杂PDF布局转换为Word可能存在限制，建议：
1. 先提取文本，再手动排版
2. 使用PDF转图片+OCR识别的方式

```
## 使用示例
### REST API 测试
```python
from api_test_automation import RestClient, RestConfig
# 创建客户端
config = RestConfig(
base_url="https://jsonplaceholder.typicode.com",
timeout=30,
retries=3
)
client = RestClient(config)
# GET 请求
response = client.get("/posts/1")
print(response.json())
# POST 请求
data = {"title": "foo", "body": "bar", "userId": 1}
response = client.post("/posts", json=data)
print(response.status_code)
# 使用认证
client.set_auth(token="your-api-token")
response = client.get("/protected-resource")
# 异步请求
import asyncio
async def test_async():
async with client.async_session() as session:
response = await session.get("/posts/1")
return response.json()
result = asyncio.run(test_async())
```
### GraphQL 测试
```python
from api_test_automation import GraphQLClient
# 创建客户端
client = GraphQLClient(endpoint="https://api.example.com/graphql")
# Query 查询
query = """
query GetUser($id: ID!) {
user(id: $id) {
id
name
email
}
}
"""
result = client.query(query, variables={"id": "123"})
print(result)
# Mutation 操作
mutation = """
mutation CreateUser($input: CreateUserInput!) {
createUser(input: $input) {
id
name
}
}
"""
result = client.mutate(mutation, variables={"input": {"name": "John"}})
# 内省查询
schema = client.introspect()
print(schema)
```
### 性能测试
```python
from api_test_automation import PerformanceTester
# 创建性能测试器
tester = PerformanceTester(
base_url="https://api.example.com",
concurrency=50,
duration=60
)
# 定义测试场景
async def scenario():
return await tester.client.get("/api/users")
# 运行负载测试
results = tester.run_load_test(scenario, total_requests=1000)
# 生成报告
print(f"平均响应时间: {results.avg_response_time}ms")
print(f"吞吐量: {results.throughput} req/s")
print(f"错误率: {results.error_rate}%")
```
### 契约测试
```python
from api_test_automation import ContractTester
# 从 OpenAPI 规范创建测试
tester = ContractTester.from_openapi("openapi.yaml")
# 验证端点
tester.validate_endpoint("/users", method="GET")
# 使用 Schemathesis 进行自动化测试
tester.run_schemathesis_tests(base_url="https://api.example.com")
```
### Mock 服务
```python
from api_test_automation import MockServer, MockRoute
# 创建 Mock 服务器
server = MockServer(port=8080)
# 添加路由
server.add_route(
MockRoute()
.method("GET")
.path("/api/users")
.response(200, {"users": [{"id": 1, "name": "Alice"}]})
.delay(0.1)
)
server.add_route(
MockRoute()
.method("POST")
.path("/api/users")
.response(201, {"id": 2, "name": "Bob"})
)
# 启动服务器
server.start()
# 使用 Mock 进行测试
# ... 你的测试代码 ...
# 停止服务器
server.stop()
```
### 测试报告
```python
from api_test_automation import TestReporter
# 创建报告器
reporter = TestReporter(output_dir="./reports")
# 生成 HTML 报告
reporter.generate_html_report(test_results)
# 生成 Allure 报告
reporter.generate_allure_report(test_results)
# 生成 JUnit XML
reporter.generate_junit_xml(test_results)
```
## 运行测试
```bash
# 运行所有测试
pytest tests/
# 运行特定测试
pytest tests/test_api_suite.py -v
# 生成 Allure 报告
pytest tests/ --alluredir=./allure-results
allure serve ./allure-results
```
## 配置文件
可以使用 YAML 文件配置测试：
```yaml
# api-config.yaml
base_url: https://api.example.com
auth:
type: bearer
token: API_TOKEN
endpoints:
- name: get_users
path: /users
method: GET
expected_status: 200
- name: create_user
path: /users
method: POST
expected_status: 201
performance:
concurrency: 50
duration: 60
ramp_up: 10
```
## 进阶用法
### 自定义请求拦截器
```python
from api_test_automation import RestClient
class LoggingInterceptor:
def before_request(self, request):
print(f"Request: {request.method} {request.url}")
def after_response(self, response):
print(f"Response: {response.status_code}")
client = RestClient()
client.add_interceptor(LoggingInterceptor())
```
### 数据驱动测试
```python
import pytest
from api_test_automation import RestClient
client = RestClient(base_url="https://api.example.com")
@pytest.mark.parametrize("user_id,expected_name", [
(1, "Alice"),
(2, "Bob"),
(3, "Charlie"),
])
def test_get_user(user_id, expected_name):
response = client.get(f"/users/{user_id}")
assert response.json()["name"] == expected_name
```
### 断言工具
```python
from api_test_automation import Assertions
response = client.get("/api/users")
# JSON 断言
Assertions.assert_json_contains(response, "users")
Assertions.assert_json_path(response, "$.users[0].name", "Alice")
# Schema 断言
Assertions.assert_json_schema(response, user_schema)
# Header 断言
Assertions.assert_header_contains(response, "content-type", "application/json")
```

## 安装
```bash
pip install -r requirements.txt
# Playwright 浏览器
playwright install chromium
```
## 依赖要求
- Python 3.8+
- requests >= 2.28
- scrapy >= 2.10
- playwright >= 1.35
- beautifulsoup4 >= 4.12
- lxml >= 4.9
- fake-useragent >= 1.2
## 快速开始
### 简单爬取
```python
from scripts.crawler import Crawler
crawler = Crawler()
html = crawler.fetch('https://example.com')
data = crawler.extract(html, {
'title': '//h1/text()',
'price': '.price::text'
})
print(data) # {'title': '...', 'price': '...'}
```
### 批量爬取
```python
from scripts.batch_crawler import BatchCrawler
urls = ['https://site.com/page/{}'.format(i) for i in range(1, 11)]
crawler = BatchCrawler(concurrent=5, delay=(1, 3))
results = crawler.crawl(urls)
```
### 动态页面
```python
from scripts.dynamic_crawler import DynamicCrawler
crawler = DynamicCrawler()
html = crawler.fetch('https://spa-app.com', wait_for='.content-loaded')
data = crawler.extract(html, {'items': '.product-item'})
```
## API 文档
### Crawler
```python
Crawler(proxy_pool=None, delay_range=(0, 0), user_agent='rotate')
```
| 参数 | 类型 | 说明 |
|------|------|------|
| proxy_pool | ProxyPool | 代理池实例 |
| delay_range | tuple | 请求间隔范围(秒) |
| user_agent | str | User-Agent策略 |
### 提取规则
```python
# XPath
data = crawler.extract(html, {'title': '//h1/text()'})
# CSS Selector
data = crawler.extract(html, {'price': '.price::text'})
# 属性提取
data = crawler.extract(html, {'link': 'a::attr(href)'})
# JSONPath (for JSON response)
data = crawler.json_extract(json_data, '$.items[*].name')
```
## 反爬虫策略
### 代理池
```python
from scripts.proxy_pool import ProxyPool
pool = ProxyPool([
'http://proxy1:8080',
'http://user:pass@proxy2:8080'
])
crawler = Crawler(proxy_pool=pool)
```
### 请求频率控制
```python
crawler = Crawler(
delay_range=(1, 3),
max_retries=3,
timeout=30
)
```

**Q: 如何在没有网络的环境中安装？**
A: 在联网机器上执行 `python scripts/download_models.py` 下载模型，然后将整个项目复制到离线环境。
**Q: 加密 PDF 如何处理？**
A: 解析时提供密码参数：`parser.parse("加密.pdf", password="your_password")`
**Q: 大文件解析崩溃怎么办？**
A: 系统会自动拆分处理，无需手动干预。如需调整拆分阈值，修改 `config/parser_config.yaml` 中的 `chunk_size`。
**Q: 如何接入自定义模型？**
A: 修改 `config/model_config.yaml`，指定自定义模型的本地路径即可。

engine = WorkflowEngine()
# 创建工作流
workflow = engine.create_workflow(
name="微信文件自动备份",
description="微信收到文件后自动备份到阿里云盘"
)
# 添加触发节点
trigger_id = engine.add_node(
workflow_id=workflow.id,
name="微信收到文件",
node_type=NodeType.TRIGGER,
platform="wechat",
action="file_received"
)
# 添加动作节点
action_id = engine.add_node(
workflow_id=workflow.id,
name="上传到阿里云盘",
node_type=NodeType.ACTION,
platform="aliyun_drive",
action="upload_file"
)
# 连接节点
engine.connect_nodes(workflow.id, trigger_id, action_id)
# 执行流程
result = engine.run(workflow.id)
print(f"执行结果: {'成功' if result.success else '失败'}")
```
### AI生成流程
```python
from scripts.ai_flow_generator import AIFlowGenerator
ai_gen = AIFlowGenerator()
# 自然语言指令生成流程
workflow = ai_gen.generate("微信收到文件后自动同步到阿里云盘")
# 获取优化建议
suggestions = ai_gen.suggest_optimization(workflow)
```
### 使用模板
```python
from scripts.template_center import TemplateCenter
from scripts.workflow_engine import WorkflowEngine
templates = TemplateCenter()
engine = WorkflowEngine()
# 从模板创建工作流
workflow = templates.create_workflow_from_template(
template_id="tpl_wechat_to_aliyun",
workflow_engine=engine
)
# 搜索模板
results = templates.search_templates("文件同步")
```
### 连接器管理
```python
from scripts.connector_manager import ConnectorManager
manager = ConnectorManager()
# 获取授权URL
auth_url = manager.get_auth_url('wechat')
# 完成授权
auth = manager.authorize('wechat', auth_code='xxx')
# 执行操作
result = manager.execute_action(
platform='wechat',
action='send_message',
params={'to': 'user', 'content': 'Hello'}
)
```
### 执行监控
```python
from scripts.execution_monitor import ExecutionMonitor
monitor = ExecutionMonitor()
# 开始执行监控
monitor.start_execution('exec_001', 'wf_001', '测试流程')
# 记录节点执行
monitor.log_node_start('exec_001', 'node_1', '触发器', 'wechat', 'file_received')
monitor.log_node_complete('exec_001', 'node_1', ExecutionStatus.SUCCESS)
# 获取执行报告
report = monitor.get_execution_report('exec_001')
# 导出日志
filepath = monitor.export_logs(format='json')
```
### 权限管理
```python
from scripts.permission_manager import PermissionManager, UserRole
pm = PermissionManager()
# 创建用户
admin = pm.create_user('admin_001', '管理员', UserRole.ADMIN)
member = pm.create_user('member_001', '成员', UserRole.MEMBER)
# 检查权限
has_permission = pm.check_permission('member_001', 'workflow:create')
# 提交审批
approval = pm.submit_approval('wf_001', '重要流程', 'member_001')
# 处理审批
pm.process_approval(approval.id, 'admin_001', approved=True, comment='同意')
```

print(f"执行结果: {'成功' if result.success else '失败'}")
```
### AI生成流程
```python
from scripts.ai_flow_generator import AIFlowGenerator
ai_gen = AIFlowGenerator()
# 自然语言指令生成流程
workflow = ai_gen.generate("微信收到文件后自动同步到阿里云盘")
# 获取优化建议
suggestions = ai_gen.suggest_optimization(workflow)
```
### 使用模板
```python
from scripts.template_center import TemplateCenter
from scripts.workflow_engine import WorkflowEngine
templates = TemplateCenter()
engine = WorkflowEngine()
# 从模板创建工作流
workflow = templates.create_workflow_from_template(
template_id="tpl_wechat_to_aliyun",
workflow_engine=engine
)
# 搜索模板
results = templates.search_templates("文件同步")
```
### 连接器管理
```python
from scripts.connector_manager import ConnectorManager
manager = ConnectorManager()
# 获取授权URL
auth_url = manager.get_auth_url('wechat')
# 完成授权
auth = manager.authorize('wechat', auth_code='xxx')
# 执行操作
result = manager.execute_action(
platform='wechat',
action='send_message',
params={'to': 'user', 'content': 'Hello'}
)
```
### 执行监控
```python
from scripts.execution_monitor import ExecutionMonitor
monitor = ExecutionMonitor()
# 开始执行监控
monitor.start_execution('exec_001', 'wf_001', '测试流程')
# 记录节点执行
monitor.log_node_start('exec_001', 'node_1', '触发器', 'wechat', 'file_received')
monitor.log_node_complete('exec_001', 'node_1', ExecutionStatus.SUCCESS)
# 获取执行报告
report = monitor.get_execution_report('exec_001')
# 导出日志
filepath = monitor.export_logs(format='json')
```
### 权限管理
```python
from scripts.permission_manager import PermissionManager, UserRole
pm = PermissionManager()
# 创建用户
admin = pm.create_user('admin_001', '管理员', UserRole.ADMIN)
member = pm.create_user('member_001', '成员', UserRole.MEMBER)
# 检查权限
has_permission = pm.check_permission('member_001', 'workflow:create')
# 提交审批
approval = pm.submit_approval('wf_001', '重要流程', 'member_001')
# 处理审批
pm.process_approval(approval.id, 'admin_001', approved=True, comment='同意')
```

---
## 快速开始
### 基础用法 - 装饰器方式
```python
from scripts.retry_handler import RetryHandler
handler = RetryHandler()
@handler.with_retry(max_attempts=3, backoff_strategy='exponential')
def my_api_call():
"""模拟API调用，失败会自动重试"""
response = requests.get('https://api.example.com/data')
return response.json()
# 执行（失败会自动重试）
result = my_api_call()
print(f"结果: {result}")
```
### 基础用法 - 编程式调用
```python
from scripts.retry_handler import RetryHandler
handler = RetryHandler()
def unstable_api(param):
# 模拟不稳定的API
if random.random() < 0.7:
raise ConnectionError("网络波动")
return {"data": param}
# 编程式调用
result = handler.execute_with_retry(
func=unstable_api,
args=("test_param",),
max_attempts=3,
backoff_strategy='exponential'
)
if result.success:
print(f"成功: {result.result}")
else:
print(f"失败: {result.exception}")
```
---
## API 参考
### RetryHandler - 重试处理器
#### 装饰器方式
```python
@handler.with_retry(
max_attempts=3, # 最大重试次数 (默认3)
backoff_strategy='exponential', # 退避策略: exponential/fixed/custom
delays=[1, 3, 5], # 自定义间隔列表 (custom策略使用)
fixed_delay=3.0, # 固定间隔时长
max_total_duration=300.0, # 最大总重试时长
on_retry=None, # 重试回调函数 (exception, attempt, delay) -> None
on_failure=None # 失败回调函数 (exception, attempt, max_attempts) -> None
)
def your_function():
pass
```
#### 编程式调用
```python
result = handler.execute_with_retry(
func=your_function,
args=(), # 位置参数元组
kwargs={}, # 关键字参数字典
max_attempts=3,
# ... 其他参数同装饰器
)
# 返回 RetryResult 对象
result.success # bool: 是否成功
result.result # Any: 执行结果

except Exception as e:
if classifier.is_retryable(e):
print(f"可重试异常: {e}")
else:
print(f"不可重试异常: {e}")
# 获取详细分类信息
category = classifier.classify(e) # RETRYABLE / NON_RETRYABLE / UNKNOWN
details = classifier.get_exception_details(e)
# {
# 'exception_type': 'ConnectionError',
# 'message': '连接超时',
# 'status_code': None,
# 'category': 'retryable',
# 'is_retryable': True,

backup_func=get_weather_backup, # 备用工具函数
param_mapping={'city': 'location'}, # 参数映射 {原参数: 备用参数}
priority=FallbackPriority.HIGH_QUALITY, # 优先级
success_rate=0.98, # 历史成功率
is_official=True, # 是否官方认证

)
# 2. 执行并自动切换
result = fallback.execute_with_fallback(
primary_func=get_weather_primary,
primary_name='weather-api-primary',

filepath='audit.xlsx', # 导出路径
task_id='task-001' # 指定任务，None则导出全部
)
# 生成任务报告
report = logger.generate_report('task-001')
```
---
### ConfigManager - 配置管理器
```python
from scripts.config_manager import ConfigManager
# 使用默认配置
config = ConfigManager()
# 使用自定义配置文件
config = ConfigManager(config_path='/path/to/config.yaml')

policy = config.get_policy('network_timeout')
print(f"重试次数: {policy.max_attempts}")
print(f"退避策略: {policy.backoff_strategy}")
print(f"间隔: {policy.delays}")
# 获取用户自定义策略
user_policy = config.get_user_policy('aggressive')
# 异常分类检查
is_retryable = config.is_retryable_exception('ConnectionError')
is_retryable = config.is_retryable_exception('429') # HTTP状态码
# 获取平台限制
limits = config.get_platform_limits()
print(f"最大重试: {limits['max_retry_attempts']}")
# 热更新配置
config.reload_config()
# 保存配置
config.save_config('/path/to/new_config.yaml')
```
