python处理apiDoc转swagger

需要转换的接口

现在我需要转换的接口全是nodejs写的数据，而且均为post传输的json格式接口

apiDoc格式

apiDoc代码中的格式如下：

/**
 * @api {方法} 路径 标题
 * @apiGroup Group
 * @apiDescription 描述这个API的信息
 *
 * @apiParam {String} userName 用户名
 * @apiParamExample {json} request-example
 * {
 *  "userName": "Eve"
 * }
 *
 * @apiError {String} message 错误信息
 * @apiErrorExample  {json} error-example
 * {
 *   "message": "用户名不存在"
 * }
 * 
 * 
 * @apiSuccess {String} userName 用户名
 * @apiSuccess {String} createTime 创建时间
 * @apiSuccess {String} updateTime 更新时间
 * @apiSuccessExample  {json} success-example
 * {
 *   "userName": "Eve",
 *   "createTime": "1568901681"
 *   "updateTime": "1568901681"
 * }
 */function getUserInfo(username) {
  // 假如这个函数是根据用户名返回用户信息的
}

使用npm安装apidoc插件：

npm install apidoc

再新建对应的apidoc.json，格式如下：

{
  "name": "文档名",
  "version": "版本号",
  "description": "解释",
  "title": "标题",
  "url" : "地址"
}

然后在apidoc.json路径下执行命令可以生成接口文档（src是接口代码文件夹，apidoc是生成文档的文件夹）：

apidoc -i src/ -o apidoc/

生成后可以在apidoc文件夹中打开index.html查看生成的接口文档，生成文档时会生成一个api_data.json，下面会用到

swagger格式

这里我们暂时只需要关注参数为json的接口格式

{
    "swagger": "2.0",
    "info": {
        "description": "1.0版本接口文档",
        "version": "1.0.5",
        "title": "智能医疗辅助平台",
        "termsOfService": "http://swagger.io/terms/"
    },
    "host": "http://localhost:8080",
    "basePath": "/",
    "tags": [],
    "paths": {},
    "definitions": {}
}

其中path是存放接口的，tags是存放的分组名列表，definitions是实体列表（json参数）

思路

使用apidoc包生成apidoc的json格式数据，然后使用python读取出接口地址、名字、组名、输入参数格式和例子、输出参数格式和例子等，然后根据swagger格式填入对应的数据即可生成swagger的json格式
我的话是会直接使用处理出的swagger的json格式的数据导入yApi中

代码

代码虽然在下面，但是是我临时着急用写的，有的地方是写死的，需要改，这里放出来主要是讲个大致的思路

import re
import json
import demjson
import decimal


# 保存时会出现byte格式问题，使用这个处理
class DecimalEncoder(json.JSONEncoder):
    def default(self, o):
        if isinstance(o, decimal.Decimal):
            return float(o)
        super(DecimalEncoder, self).default(o)


# 分析例子转json，在这里可以自己添加规则
def analyze_demjson(json_data):
    item = json_data.replace("\\n", "").replace("\\", "").replace(" ", "")
    result_item = {}
    try:
        result_item = demjson.decode(item, encoding='UTF-8')
    except:
        print(item)
    return result_item


# 获取解析apidoc数据
def get_api_doc_data(name):
    data_list = None
    group_list = {}
    with open(name, mode='r', encoding="UTF-8") as f:
        data_list = json.load(f)
    for data in data_list:
        if data['group'] in group_list:
            group_list[data['group']].append(data)
        else:
            group_list[data['group']] = [data]
    return group_list


# 转为swagger写入
def set_swagger_data(data):
    swagger_json = {
        "swagger": "2.0",
        "info": {
            "description": "1.0版本接口文档",
            "version": "1.0.5",
            "title": "智能医疗辅助平台",
            "termsOfService": "http://swagger.io/terms/"
        },
        "host": "http://localhost:8080",
        "basePath": "/",
        "tags": [],
        "paths": {},
        "definitions": {}
    }
    # 添加分组
    for group_key in data:
        swagger_json['tags'].append({
            "name": group_key,
            "description": group_key
        })
    # 添加接口信息
    # 循环分组
    for group_key in data:
        # 循环每组列表
        for interface in data[group_key]:
            parameters = {}
            if 'parameter' in interface and 'fields' in interface['parameter']:
                # 获取参数demo信息
                content = ""
                if 'examples' in interface['parameter']:
                    content = analyze_demjson(interface['parameter']['examples'][0]['content'])
                # 添加参数信息
                parameter_dict = {}
                for parameter in interface['parameter']['fields']['Parameter']:
                    parameter_type = "None"
                    if "type" in parameter:
                        parameter_type = parameter['type'].lower()
                        if parameter_type == 'number':
                            parameter_type = "integer"
                    parameter_item = {
                        "description": parameter['description'].replace('<p>', '').replace('</p>', ''),
