我正在嘗試合併上傳一個基本的文本/ csv文件到我的web應用程序,該應用程序運行燒瓶來處理http請求。我試圖按照localhost here上運行的燒瓶文檔中的寶寶示例。但是,當我在我的頁面上嘗試這段代碼時,它似乎上傳,但後來只是掛起,事實上我的瓶服務器凍結,我不得不關閉終端再試一次... Ctrl + C甚至不工作。在python燒瓶中上傳文件
我執行run.py
:
#!/usr/bin/env python
from app import app
if __name__ == '__main__':
app.run(host='0.0.0.0', port=5000, debug=False, use_reloader=False)
和app
是在同一目錄的目錄中run.py
與以下__init__.py
:
import os
from flask import Flask
from werkzeug import secure_filename
#Flask object initialization
#app flask object has to be created before importing views below
#because it calls "import app from app"
UPLOAD_FOLDER = '/csv/upload'
ALLOWED_EXTENSIONS = set(['txt', 'csv'])
app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
,這裏是我的views.py
文件,其中有我的所有路由:
from flask import render_template, request, redirect, url_for
from app import app
import os
#File extension checking
def allowed_filename(filename):
return '.' in filename and filename.rsplit('.',1)[1] in ALLOWED_EXTENSIONS
@app.route('/', methods=['GET', 'POST'])
@app.route('/index.html', methods=['GET', 'POST'])
def index():
if request.method == 'POST':
submitted_file = request.files['file']
if submitted_file and allowed_filename(submitted_file):
filename = secure_filename(submitted_file.filename)
submitted_file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
return redirect(url_for('uploaded_file', filename=filename))
return '''
<!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>
'''
有人可以告訴我字符串「uploaded_file」來自哪裏嗎? – computingfreak
