如何将控制台输出写入 Flask 中的文本文件？
我正在使用 Ubuntu、python3 和 Flask 服务器。我只想将打印在终端上的行 print('**found file', file.filename, '\n') 保存到文本文件中。
任何形式的帮助将不胜感激。提前致谢。
import os
from flask import Flask, request, redirect, url_for, send_from_directory, jsonify
from werkzeug import secure_filename
UPLOAD_FOLDER = 'uploads'
ALLOWED_EXTENSIONS = set(['txt', 'pdf', 'png', 'jpg', 'jpeg', 'mp4'])
app = Flask(__name__)
app.config['UPLOAD_FOLDER'] = UPLOAD_FOLDER
def allowed_file(filename):
# this has changed from the original example because the original did not work for me
return filename[-3:].lower() in ALLOWED_EXTENSIONS
@app.route('/', methods=['GET', 'POST'])
def upload_file():
if request.method == 'POST':
file = request.files['file']
if file and allowed_file(file.filename):
print('**found file', file.filename, '\n')
filename = secure_filename(file.filename)
file.save(os.path.join(app.config['UPLOAD_FOLDER'], filename))
return jsonify({"success" : 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>
'''
@app.route('/uploads/<filename>')
def uploaded_file(filename):
return send_from_directory(app.config['UPLOAD_FOLDER'],
filename)
if __name__ == '__main__':
app.run(host= '0.0.0.0', debug=True)
