Python进阶(五十一)-Flask文件上传提示PermissionError: [Errno 13] Permission denied: ‘E:\IDEA Projects\Data’

  在学习Flask文件上传过程中，按照视频教学中的示例代码敲了一遍，执行时却提示’PermissionError: [Errno 13] Permission denied: ‘E:\IDEA Projects\Data‘的错误，但是视频中却是可以正常操作。具体代码如下：

@app.route('/upload', methods=['GET', 'POST'])
def upload():
    if request.method == 'POST':
        f = request.files['file']
        basepath = path.abspath(path.dirname(__file__))
        upload_path = path.join(basepath, 'static\\uploads')
        f.save(upload_path, secure_filename(f.filename))
        return redirect(url_for('upload'))
    return render_template('upload.html')

  经过网络搜索，将代码更改为如下代码时，文件可以成功上传。

@app.route('/upload', methods=['GET', 'POST'])
def upload():
    if request.method == 'POST':
        f = request.files['file']
        basepath = path.abspath(path.dirname(__file__))
        upload_path = path.join(basepath, 'static', 'uploads', secure_filename(f.filename))
        f.save(upload_path)
        return redirect(url_for('upload'))
    return render_template('upload.html')

  经过代码对比，发现原来是save()方法的参数搞错了。
