3.flask配合脚本上传文件

@chang.route('/sc',methods = ['POST'])
def sc():
    if request.method=='POST':
        f = request.files["file"]
        base_path = path.abspath(path.dirname(__file__))
        upload_path = path.join(base_path)
        file_name = upload_path + secure_filename(f.filename)
        f.save(file_name)
        return redirect(url_for('upload'))
    return render_template('upload.html')

sc_url = 'http://127.0.0.1:5000/sc'
files = {'file': ('ceshi.jpg', open('ceshi.jpg', 'rb'))}
b = requests.post(sc_url,files = files,timeout=10)
