没有这样的文件或目录：/uploads

Question

我查看了其他几个问题，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？错误消息中的正斜杠和反斜杠有什么区别？

谢谢

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 %}

/uploads表示绝对链接（C:/upload），因此您应该使用upload/它。

另外，您可以使用/sf/answers/1418040781/中的精彩片段

APP_ROOT = os.path.dirname(os.path.abspath(__file__))
UPLOAD_FOLDER = os.path.join(APP_ROOT, 'static/uploads')
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
