About integrating superset into your own project

 下载&安装

方式一：pip install apache-superset

方式二：https://github.com/apache/superset.git

---

搭建虚拟环境（可选）

1.安装anaconda  （https://www.anaconda.com/products/individual#Downloads）

2.anaconda下run一个python环境,（推荐python3.8）

---

运行

1.superset db upgrade  #初始化数据库 

2.superset fab create-admin  #初始化用户

3.superset init            # 初始化

4.superset run -h 0.0.0.0 -p 8088 --with-threads --reload --debugger  # 启动

This process may have many pit,I met a few listed below and the solution：

1.Python-geohash、sasl包有问题：

下载文件安装：https://www.lfd.uci.edu/~gohlke/pythonlibs/#python-geohash

2.markupsafe模块有问题：

安装201版本：pip install markupsafe==2.0.1

3.建议python-v >= 3.8

4.a "wsgi.py" or "app.py" module was not found in the current directory.

CD到app.pyUnder the directory to performsuperset run命令

5.pip install Pillow

未安装Piollow可能会导致run不起来

6.error: Microsoft Visual C++ 14.0 is required. Get it with "Build Tools for Visual Studio":

下载安装：https://visualstudio.microsoft.com/downloads/

superset的集成

本文用的方式是Button点击跳URLTo the deployment ofsuperset上,The following system and permissions to access account processing.

superset采用flask-appbuilder做身份验证,About how to access the user,The official documentation for details：Security — Flask AppBuilder

本文的思路是：拦截/loginThe request to your own project,Make the function of login and verify.At the same time to the alogin的CallBack URLLet their success in landing back tone system,在回调时把UserWrites the current system ofSession中去.Logout也是同样的道理.都是使用CallBack URL来做的.代码如下：

# config.py

from flask_appbuilder.security.manager import AUTH_REMOTE_USER
from my_security_manager import MySecurityManager

AUTH_TYPE = AUTH_REMOTE_USER # 设置模式
CUSTOM_SECURITY_MANAGER = MySecurityManager # 引入自己写的Security
AUTH_USER_REGISTRATION = True  # 允许用户注册
AUTH_USER_REGISTRATION_ROLE = "Gamma"  # Set the default add user role

# 与seperset文件夹同级目录下创建 my_security_manager.py 

LOGIN_SERVER_URL = 'http://10.113.72.88:5000/login' # Access to the system login interface
CHECK_SERVER_URL = 'http://10.113.72.88:5000/check' # Access to the system oftoken检查接口
LOGINOUT_SERVER_URL = 'http://10.113.72.88:5000/logout' # System access to the appropriate interface

class MyAuthRemoteUserView(AuthRemoteUserView):
    # 需继承config.py中AUTH_TYPEThe value corresponding to the parent class
    login_template = 'appbuilder/general/security/login_my.html'
    title = "My Login"
    
    @expose('/login/', methods=['GET', 'POST'])
    def login(self):
        token = request.args.get('token')
        if not token:
            token = request.cookies.get('access_token')
        if not token:
            return redirect(LOGIN_SERVER_URL)
        manager = self.appbuilder.sm
        # According to modify your system parameters
        result = requests.get(CHECK_SERVER_URL + '?token=' + token) 
        # According to modify your system validation condition
        if result.status_code != 200:
            return redirect(LOGIN_SERVER_URL)
        
        # Where access is,只验证token是否有效,All users to entersupersetSee the same page
        # 同一个superset账号（admin）
        username = "admin"
        user = manager.find_user(username=username)
        login_user(user, remember=False)
        return redirect(self.appbuilder.get_url_for_index)

        # Can also according to different login account insupersetGenerated in the different account,Different user interface is different.                            
        # Equivalent to the corresponding access system account number insuperset中进行创建,同时修改login方法,In the custom login.
# if token is not None:
#     jwt_payload = jwt.decode(token, 'secret', algorithms=['RS256'])
#     user_name = jwt_payload.get("user_name")
#     user = self.appbuilder.sm.find_user(username=user_name)
#     if not user:
#         role_admin = self.appbuilder.sm.find_role('Admin')
#         user = self.appbuilder.sm.add_user(user_name, user_name, 'aimind', user_name + "@aimind.com", role_admin, password="aimind" + user_name)
#     if user:
#         login_user(user, remember=False)
#         redirect_url = request.args.get('redirect')
#         if not redirect_url:
#             redirect_url = self.appbuilder.get_url_for_index
#         return redirect(redirect_url)
#     else:
#         return super(AuthRemoteUserView, self).login()


class MySecurityManager(MyAuthRemoteUserView):
    authremoteuserview = MyAuthRemoteUserView
