NebulaAPI - 万物皆 API

NebulaAPI 是一个轻量级、灵活且强大的 RESTful API 框架,旨在将任何数据源快速转化为 API。无论是 CSV、Excel、Pandas DataFrame,还是 MongoDB 等数据源,NebulaAPI 都能轻松将其转化为可用的 API,并提供自动化的路由生成和强大的扩展能力。

核心功能

1. 万物皆 API

  • 任何数据源都可以转化为 API:无论是结构化数据(如 CSV、Excel、DataFrame)还是非结构化数据(如 MongoDB、JSON 文件),NebulaAPI 都能将其快速转化为 RESTful API。
  • 基于 Excel 文件的数据源:NebulaAPI 允许你直接使用 Excel 文件作为数据源,无需数据库,即可提供数据服务,适合小型项目或快速原型开发。

2. 支持多种数据格式

  • CSV/Excel 自动转化:直接传入 CSV 或 Excel 文件,NebulaAPI 会自动解析数据并生成对应的 API。
  • Pandas DataFrame 支持:可以直接传入 Pandas DataFrame,NebulaAPI 会将其转化为 API。
  • MongoDB 支持:通过传入 MongoDB 连接字符串,NebulaAPI 可以自动将 MongoDB 集合转化为 API。

3. 自动化与灵活性并存

  • 自动生成 API:NebulaAPI 会自动为每个数据表生成标准的 CRUD(增删改查)API,无需手动编写代码。
  • 支持手动扩展:除了自动生成的 API,你还可以手动注册自定义路由,灵活控制 API 的行为。
  • 自定义 CRUD 逻辑:通过自定义 CRUD 类,你可以完全控制数据的处理逻辑,满足复杂业务需求。

4. Swagger 文档支持

  • 自动生成 API 文档:NebulaAPI 会自动生成 Swagger 文档,方便开发者查看和测试 API。
  • 实时更新:每次注册新的路由或修改现有路由时,Swagger 文档都会自动更新。

5. 强大的查询能力

  • 灵活的条件查询:支持通过字典条件进行查询、更新和删除操作,满足复杂的数据过滤需求。
  • 分页支持:自动为数据表添加分页功能,方便处理大量数据。

快速开始

安装依赖

确保你已经安装了 Flask 和 Pandas 还有NebulaDataEngine:

pip install Flask pandas  NebulaDataEngine 

示例 1:从 Excel 文件生成 API

假设你有一个 products.xlsx 文件,内容如下:

id name price category
1 Apple 0.5 Fruit
2 Banana 0.3 Fruit
3 Carrot 0.2 Vegetable
4 Date 2.0 Fruit

通过以下代码,你可以将 products.xlsx 转化为 API:

from nebula_api_v3 import NebulaAPI

# 初始化 NebulaAPI,传入 Excel 文件路径
api = NebulaAPI(data_source="products.xlsx", enable_docs=True, enable_crud=True)

# 启动服务器
api.run_server(host='localhost', port=5000)

启动后,你可以访问api文档地址 http://localhost:5000/api/docs/#/ 可以看到以下接口:

  • 获取所有产品

    GET /api/products
    
  • 添加新产品

    POST /api/products/add
    
  • 更新产品信息

    PUT /api/products/edit/{id}
    
  • 删除产品

    DELETE /api/products/delete/{id}
    
  • 通过条件查询产品

    POST /api/products/find
    

示例 2:从 Pandas DataFrame 生成 API

如果你已经有 Pandas DataFrame,可以直接将其转化为 API:

from nebula_api_v3 import NebulaAPI
import pandas as pd

# 创建示例 DataFrame
data = {
    'user': pd.DataFrame({
        'id': [1, 2, 3, 4],
        'name': ['Alice', 'Bob', 'Charlie', 'David'],
        'age': [24, 27, 22, 32],
        'city': ['New York', 'Los Angeles', 'Chicago', 'Houston']
    })
}

# 初始化 NebulaAPI,传入 DataFrame
api = NebulaAPI(data_source=data, enable_docs=True, enable_crud=True)

# 启动服务器
api.run_server(host='localhost', port=5000)

示例 3:自定义 CRUD 逻辑

如果你想自定义 CRUD 逻辑,可以通过以下方式实现:

from nebula_api_v3 import NebulaAPI
import pandas as pd

# 自定义 CRUD 类
class CustomCRUD:
    def __init__(self, data_engine, table_name):
        self.data_engine = data_engine
        self.table_name = table_name

    def add(self, data):
        # 自定义添加逻辑
        self.data_engine.save(data, self.table_name)
        return {"message": "数据添加成功(自定义逻辑)"}

    def edit(self, id, data):
        # 自定义更新逻辑
        data['id'] = id
        self.data_engine.save(data, self.table_name)
        return {"message": "数据更新成功(自定义逻辑)"}

    def delete(self, id):
        # 自定义删除逻辑
        self.data_engine.deleteById(id, self.table_name)
        return {"message": "数据删除成功(自定义逻辑)"}

    def get(self, id):
        # 自定义获取逻辑
        data = self.data_engine.findById(id, self.table_name)
        if data:
            return data
        else:
            return {"error": "数据未找到(自定义逻辑)"}, 404

# 初始化 NebulaAPI
api = NebulaAPI(data_source=data, enable_docs=True, enable_crud=True)

# 注册自定义 CRUD 逻辑
custom_crud = CustomCRUD(api.data_engine, "user")
api.register_custom_crud_routes("user", custom_crud)

# 启动服务器
api.run_server(host='localhost', port=5000)

适用场景

  • 快速原型开发:无需编写大量代码,快速将数据转化为 API,加速开发进程。
  • 数据共享:将内部数据(如 CSV、Excel)快速转化为 API,方便其他系统或团队使用。
  • 微服务架构:将数据源封装为独立的 API 服务,支持微服务架构。
  • 自动化测试:通过 Swagger 文档,方便进行 API 测试和调试。

未来计划

  • 更多数据源支持:计划支持更多数据源,如 MySQL、PostgreSQL、Redis 等。
  • 权限控制:增加 API 权限控制功能,支持 JWT 认证和角色管理。
  • 性能优化:优化大数据量下的查询和分页性能。
  • 重构底层:目前还有挺多的硬编码 后期应该会改成基于语义的查询方法 减少大量硬编码 并增加基于语义的接口注册查询 例如 find_user_by_name 直接传入方法 或字符串等 则会生成对应接口
