【问题描述】：
我正在尝试制作一个在 SQL 数据库上上传数据和图片的表单，HTML 表单工作正常，但是当我按下提交时说页面不工作并且没有在表格上插入任何数据可以请帮忙看看我的代码有什么问题
这是我的python代码 #main.py
from flask import Flask, flash, request, redirect, url_for, render_template
import urllib.request
import os
from werkzeug.utils import secure_filename
from Dbaconnection import dbaconnect
app = Flask(__name__)
app.secret_key = "cairocoders-ednalan"
UPLOAD_FOLDER = 'static/uploads/'
app.secret_key = "secret key"
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
app.config['MAX_CONTENT_LENGTH'] = 16 * 1024 * 1024
ALLOWED_EXTENSIONS = set(['png', 'jpg', 'jpeg', 'gif'])
def allowed_file(filename):
return '.' in filename and filename.rsplit('.', 1)[1].lower() in ALLOWED_EXTENSIONS
@app.route('/')
def home():
return render_template('index.html')
@app.route('/webproject', methods=['GET','POST'])
def upload_image():
if 'file' not in request.files:
flash('No file part')
return redirect(request.url)
file = request.files['file']
if file.filename == '':
flash('No image selected for uploading')
return redirect(request.url)
if file and allowed_file(file.filename):
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
data=request.form
db = dbaconnect();
dbcursor = db.cursor()
print(data['file'])
dbcursor.execute("INSERT INTO webproject(name,Address,Photo) VALUES(%s,%s,%s)",(data['Name'],data['Address'],data['Photo'],))
db.commit()
flash('Image successfully uploaded and displayed below')
return render_template('index.html', filename=filename)
else:
flash('Allowed image types are - png, jpg, jpeg, gif')
return redirect(request.url)
@app.route('/display/<filename>')
def display_image(filename):
return redirect(url_for('static', filename='uploads/' + filename), code=301)
if __name__ == "__main__":
app.run(debug=True)
