Flask应用程序在Heroku上部署时无法在本地保存图像

标签: python flask dropzone

我写了一个应用https://images99acres.herokuapp.com/

此应用程序允许用户上传图像,如果我在本地运行此应用程序,则此应用程序将上传图像并将其保存到我指定的路径中,

但是我在Heroku上上传了此应用,当有人上传图片时,它在https://images99acres.herokuapp.com/_uploads/photos/activate%20virtual_environment.jpg上上传了图片

“ _ uploads / photos / image.jpg”

下面是我的代码:

from flask import Flask, redirect, render_template, request, session, url_for
from flask_dropzone import Dropzone
from flask_uploads import UploadSet, configure_uploads, IMAGES, patch_request_class

import os

app = Flask(__name__)
dropzone = Dropzone(app)


app.config['SECRET_KEY'] = 'supersecretkeygoeshere'

# Dropzone settings
app.config['DROPZONE_UPLOAD_MULTIPLE'] = True
app.config['DROPZONE_ALLOWED_FILE_CUSTOM'] = True
app.config['DROPZONE_ALLOWED_FILE_TYPE'] = 'image/*'
app.config['DROPZONE_REDIRECT_VIEW'] = 'results'

# Uploads settings
app.config['UPLOADED_PHOTOS_DEST'] = os.getcwd() + '/uploads'

photos = UploadSet('photos', IMAGES)
configure_uploads(app, photos)
patch_request_class(app)  # set maximum file size, default is 16MB


@app.route('/', methods=['GET', 'POST'])
def index():

    # set session for image results
    if "file_urls" not in session:
        session['file_urls'] = []
    # list to hold our uploaded image urls
    file_urls = session['file_urls']

    # handle image upload from Dropszone
    if request.method == 'POST':
        file_obj = request.files
        for f in file_obj:
            file = request.files.get(f)

            # save the file with to our photos folder
            filename = photos.save(
                file,
                name=file.filename    
            )

            # append image urls
            file_urls.append(photos.url(filename))

        session['file_urls'] = file_urls
        return "uploading..."
    # return dropzone template on GET request    
    return render_template('index.html')


@app.route('/results')
def results():

    # redirect to home if no images to display
    if "file_urls" not in session or session['file_urls'] == []:
        return redirect(url_for('index'))

    # set the file_urls and remove the session variable
    file_urls = session['file_urls']
    session.pop('file_urls', None)

    return render_template('results.html', file_urls=file_urls)

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

#app.run(debug=True)

我该怎么办?我该如何解决?
