我看了几个其他问题,但无法弄清楚出了什么问题。我收到以下错误:“FileNotFoundError:[Errno 2]没有这样的文件或目录:'/ uploads\MRRtest.csv'”任何人都可以帮忙吗?错误消息的正斜率和反斜杠之间有什么区别?
由于
from flask import Flask, render_template, request, redirect, url_for, flash
from flask.ext.bootstrap import Bootstrap
from werkzeug import secure_filename
import os
app = Flask(__name__)
bootstrap = Bootstrap(app)
UPLOAD_FOLDER = '/uploads'
ALLOWED_EXTENSIONS = set(['csv'])
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
def allowed_file(filename):
return '.' in filename and \
filename.rsplit('.', 1)[1] in ALLOWED_EXTENSIONS
@app.route('/', methods=['GET', 'POST'])
def index():
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('uploaded_file', filename=filename))
return render_template('index.html')
我的index.html模板如下:
{% extends "base.html" %}
{% block title %}Flasky{% endblock %}
{% block page_content %}
<div class="page-header">
<h1>Upload File</h1>
<form action="" method=post enctype=multipart/form-data>
<p><input type=file name=file>
<input type=submit value=Upload>
</form>
</div>
{% endblock %}

var books = books.Where(x => x.author == search).ToList();
表示绝对链接(C:/ upload),因此您应该使用/uploads
代替。
另外,您可以使用https://stackoverflow.com/a/20257725/5851179

从评论中我意识到我的uploads目录与run.py文件位于同一目录中,而不是index.html运行的'templates'目录。我修改了
APP_ROOT = os.path.dirname(os.path.abspath(__file__))
UPLOAD_FOLDER = os.path.join(APP_ROOT, 'static/uploads')
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
到
UPLOAD_FOLDER = '/uploads'
我现在正在构建“url for endpoint”
感谢您的帮助。
