python-将图像上传到目录，保存并重命名
[英]python - upload image into directory, save it and rename it
问题描述
我想上传图像“ camera.jpg”并将其保存到“ static / photo /”目录，然后将“ camera.jpg”文件重命名为“ niloofar.jpg”文件。
我怎样才能做到这一点？
app.py：
from flask import Flask, request, url_for, render_template, make_response, redirect
from flask_sqlalchemy import SQLAlchemy
from werkzeug.utils import secure_filename
UPLOAD_FOLDER = '/home/me/my_flask_project/static/photo/'
ALLOWED_EXTENSIONS = set(['txt', 'pdf', 'png', 'jpg', 'jpeg', 'gif'])
app = Flask(__name__)
app.config['SQLALCHEMY_DATABASE_URI'] = 'mysql://myusername:mypassword@localhost/mydbname'
db = SQLAlchemy(app)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
def allowed_file(filename):
return '.' in filename and \
filename.rsplit('.', 1)[1] in ALLOWED_EXTENSIONS
@app.route('/upload/', methods=['GET', 'POST'])
def upload_file():
if request.method == 'POST':
file = request.files['file']
if file and allowed_file(file.filename):
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
#return redirect(url_for('upload_file', filename=filename))
os.rename(UPLOAD_FOLDER + filename, 'niloofar.jpg')
return render_template('upload.html')
if __name__ == '__main__':
app.run()
upload.html：
<!doctype html>
<title>Upload new File</title>
<h1>Upload new File</h1>
<form action="" method=post enctype=multipart/form-data>
<p><input type=file name=file>
<input type=submit value=Upload>
</form>
我也在下面尝试了此脚本，但它甚至没有将图像保存到“照片”目录中：
import os, sys
@app.route('/upload/', methods=['GET', 'POST'])
def upload_file():
if request.method == 'POST':
file = request.files['file']
if file and allowed_file(file.filename):
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
#return redirect(url_for('upload_file', filename=filename))
os.rename(UPLOAD_FOLDER + filename, 'niloofar.jpg')
return render_template('upload.html')
问题是什么？

尝试在os.rename给出完整的目标路径。
os.rename(UPLOAD_FOLDER + filename, UPLOAD_FOLDER+'niloofar.jpg')
