python 基於flask的簡單web查詢程式

3個.py檔案

create_html.py # 利用pandas 將result生成 **形式

mysql.py #連線資料庫獲取資料.

from flask import flask

from flask import request
from create_html import convert_to_html
from mysql import get_result
def home():
return 'home'
def signig_from():
result = get_result()#獲取資料
title = ['監護人','學校','年級','班級','學生姓名','託管時間','簽訂時間']
h=convert_to_html(result,title)
return h
#不用管下面
def signin():
if request.form['username']=='admin' and request.form['password']=='password':
return '
import pymysql
def get_result():
conn = pymysql.connect(host='***x',user='root',passwd='***',db='ygxy-sys')
cur = conn.cursor()
sql = '''select

e.s_school ,
e.s_session ,
e.s_class ,
d.name,
case param->'$[0]'
when '["0", "1", "0"]' then '中午'
when '["0", "1", "1"]' then '中午/晚上'
when '["0", "0", "1"]' then '晚上'
else '其他'  end ,

from
guardian_data as a,
student_signed_protocol as b,
guardian_ship as c,
student_data as d,
student_school as e 
where
c.main_guardian_id = a.guardian_phone 
and b.id = c.id 
and b.sid = d.sid 
and d.sid = e.sid
'''print(sql)
result = [,,,,,,]
try:
cur.execute(sql)
results = cur.fetchall()
for row in results:
for i in range(0,7):
except exception as e:
print(e)
finally:
return result
conn.close()

從資料庫裡取出的值格式不是這樣,所以需要做如下操作,把同一列值都放到乙個list中

result = [,,,,,,]

try:
cur.execute(sql)
results = cur.fetchall()
for row in results:
for i in range(0,7):

import pandas as pd

from mysql import get_result
def convert_to_html(result,title):
d = {}
index = 0
#for row in result:
for t in title:
d[t] = result[index]
index+=1
df = pd.dataframe(d)
#如資料過長，可能在**中無法顯示，加上pd.set_option語句可以避免這一情況
pd.set_option('max_colwidth',200)
df = df [title]
h =df.to_html(index=true)
with open('11.html','w',encoding='utf-8') as f:
for eachline in h:
f.write(eachline)
return h
if __name__=="__main__":
result = get_result()
title = ['監護人','學校','年級','班級','學生姓名','託管時間','簽訂時間']
convert_to_html(result,title)

基於Flask的最簡Web請求
