在工作中，会导出一份mysql的html来查看，用的是就是路过秋天大神的那个工具，所以想自己用那个样式直接在后端写一个页面做展示！
前端页面
from flask import Flask,request,render_template from flask_sqlalchemy import SQLAlchemy app = Flask(__name__) app.config['SQLALCHEMY_DATABASE_URI'] = 'sqlite:///test.db' #这里用这个是不行的 注意修改为ｍｙｓｑｌ 才可以正常使用 db = SQLAlchemy(app) @app.route("/listModel", methods=["GET"]) def listModel(): dbName = request.args.get("dbname","ｘｘ") tableStr = """select table_name,table_comment from information_schema.tables where TABLE_TYPE='BASE TABLE' and table_schema='{}'""".format( dbName) resultList = db.engine.execute(tableStr) _infoList = [] if resultList: for index, result in enumerate(resultList): tableName = result[0] filedStr = """select ORDINAL_POSITION,column_name,COLUMN_COMMENT,DATA_TYPE,CHARACTER_MAXIMUM_LENGTH,numeric_precision,numeric_scale,COLUMN_KEY,COLUMN_DEFAULT,IS_NULLABLE from information_schema.columns where table_schema='{}' and table_name='{}'""".format( dbName, tableName) filedList = db.engine.execute(filedStr) _infolist = [] if filedList: for field in filedList: if field[5]: CHARACTER_MAXIMUM_LENGTH = field[5] elif field[4]: CHARACTER_MAXIMUM_LENGTH = field[4] else: CHARACTER_MAXIMUM_LENGTH = 0 if field[9] == "YES": IS_NULLABLE = "Y" else: IS_NULLABLE = "N" _infoDict = { "ORDINAL_POSITION": field[0], "column_name": field[1], "COLUMN_COMMENT": field[2], "DATA_TYPE": field[3], "CHARACTER_MAXIMUM_LENGTH": CHARACTER_MAXIMUM_LENGTH, "numeric_scale": field[6] if field[6] else 0, "COLUMN_KEY": "Y" if field[7] else "", "COLUMN_DEFAULT": field[8] if field[8] else "", "IS_NULLABLE": IS_NULLABLE, } _infolist.append(_infoDict) infoDict = { "index": index + 1, "tableName": tableName, "table_comment": result[1], "fields": _infolist } _infoList.append(infoDict) return render_template("demos.html", rows=_infoList,dbName=dbName) if __name__ == '__main__': app.run()
然后是 html 静态页面
