目的是想做一个完整的登录项目，但是出了一些很奇怪的bug
就是你输入信息之后，就只返回了一个服务器的信息如何也不打印‘注册成功’，也没有报错
点登录后，原网页也就刷新了一下
源码如下，不知道哪里错了
login.py
from flask import app,Flask,render_template,redirect,request
import pymysql
app=Flask(__name__)
@app.route('/login',methods=['GET','POST'])
def user_login():
if request.method=='GET':
return render_template('login.html')
username = request.args.get('user')
password = request.args.get('pwd')
conn=pymysql.connect(host='localhost',user='root',password='123',charset='utf8',db='unicom')
cursor=conn.cursor()
cursor.execute('''
CREATE TABLE IF NOT EXISTS info (
id INT NOT NULL AUTO_INCREMENT PRIMARY KEY,
username VARCHAR(255) NOT NULL UNIQUE,
password VARCHAR(255) NOT NULL
)
''')
try:
cursor.execute("INSERT INTO info (username, password) VALUES (%s, %s)", (username, password))
conn.commit()
return '注册成功'
except pymysql.Error as e:
print(f"Error: {e}")
return str(e)
finally:
cursor.close()
conn.close()
if __name__=='__main__':
app.run()
