我有一个功能,用Pandas分析CSV文件,并生成一个包含摘要信息的dict.我想将结果作为Flask视图的响应返回.如何返回JSON响应？

@app.route("/summary")
def summary():
    d = make_summary()
    # send it back as json

我正在尝试在我的Flask应用程序中调试一个视图,该视图返回500状态,并TypeError: 'bool' object is not callable在回溯中显示错误.login_user来自Flask-Login 的视图调用然后返回True以指示登录成功.

我已经调试app_iter = app(environ, start_response)过app,现在它是一个布尔值,True而不是Flask应用程序对象的值.
