python - 将图像上传到目录中，保存并重命名

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。python - 将图像上传到目录中，保存并重命名

我该怎么做？

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:[email protected]/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>

我也试过低于这个剧本，但它甚至不将图像保存到 “照片” 目录：

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')

什么是问题？

尝试在os.rename中给出完整的目标路径。

os.rename(UPLOAD_FOLDER + filename, UPLOAD_FOLDER+'niloofar.jpg')
