py使用flask文件上传

代码如下：

from flask import Flask, render_template, request,jsonify
from werkzeug.utils import secure_filename
import os

app = Flask(__name__)
#定义上传文件路径
app.config['UPLOAD_FOLDER'] = 'upload/'

# @app.route('/upload')
# def upload_file():
#    return render_template('upload.html')

@app.route('/uploader', methods = ['GET', 'POST'])
def uploader():
  if request.method == 'POST':
     f = request.files['file']
     f.save(os.path.join(app.config['UPLOAD_FOLDER'],secure_filename(f.filename)))
     return jsonify({'status':'ok'})

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