Question

我是烧瓶的新手。我试图使用flask将csv文件中的数据上传到MySQL。但是我收到一个错误“ _csv.Error：迭代器应返回字符串，而不是字节（您是否以文本模式打开文件？）”。如何解决？

我的代码是：

from flask import Flask,render_template, url_for, request, redirect
from flask_wtf import FlaskForm, Form
from wtforms import StringField,SubmitField
import csv
from flask_mysqldb import MySQL

myd = MySQLdb.connect(host='localhost',user='root',passwd='admin',db='user')
cur = myd.cursor()
app = Flask(__name__)
app.config['SECRET_KEY'] = '7e46de54884a3803d8bc35a52d6a6ae8'
@app.route("/uploaddb", methods=['GET','POST'])
def updb():
    files = request.files['file']
    reader = csv.DictReader(files)
    data = [row for row in reader]
    for row in data:
        systemid = row['systemid']
        school=row['school']
        phone=row['phone']
        address=row['address']
        state=row['state']
        cur.execute("INSERT INTO 
    testcsv(systemid,school,phone,address,state)" 
 "VALUES('%s','%s','%s','%s','%s','%s')",systemid,school,phone,address,state)
    myd.commit()
    cur.close()

if __name__ == '__main__':
    app.run()

我认为，您可能需要以utf-8编码模式读取CSV文件才能将字节转换为字符串

无法将烧瓶中的csv文件上传到数据库
