1. App 组件中注释 Menu， 去除顶部菜单

MenuWrapper

SubMenuComponent

2. 请求/chart/add ，直接展示绘图页
   此过程，浏览器只加载静态资源，没有api的数据请求。
   取消登录限制：
   api: GET, POST /chart/add
   view: SliceModelView.add
   源码：superset/views/chart/view.py
   取消登录： 注释has_access 登录要求

3. 选数据集，触发api请求
   api: GET- /api/v1/dataset/
   查询参数：‘q’ = “(columns:!(id,table_name,description,datasource_type),filters:!((col:table_name,opr:ct,value:‘’)),order_column:table_name,order_direction:asc,page:0,page_size:100)”
   view: DatasetRestApi.get_list
   源码：superset/datasets/api.py
   取消登录：
   flask_appbuilder/api/_init_.py 搜索get_list
   注释@protect
   显示固定的测试用例数据：
   slice: 存储创建的图表
   tables:存储用户的数据集（表名等）
   flask_appbuilder/api/_init_.py

# get_list_headless
if count == 0:
    response["result"] = [{'description': None, 'datasource_type': 'table', 'id': 1, 'table_name': 'line_t'}]
    response["ids"] = [1]
    response["count"] = 1

将测试用例数据存储的表信息存入tables

tables中的uuid不可编辑：

继续： 选择图形后，点击添加图表，发送get
 

• GET-/api/v1/explore/
  查询参数：(‘viz_type’, ‘echarts_timeseries_line’), (‘datasource_id’, ‘1’), (‘datasource_type’, ‘table’)]
   
• GET-/api/v1/database/1/table_extra/line_t/superset/

POST-/api/v1/explore/form_data-ImmutableMultiDict([(‘tab_id’, ‘5’)])

 
4. 登录功能分析
后端加一个钩子函数，查看请求交互！

# 处理请求之前
@app.before_request
def analyze():
	xxxx
	return None

/api/v1/me/ 验证用户的登录
未登录返401，前端重定向到/login/
已登录，返回用户信息

去除登录功能：

接口：GET /api/v1/me/
视图：

5. 获取flask app所有的接口

• flask routes 获取接口
• 根据api接口查找视图
• 搜索视图源码位置
