带烧瓶静止的自定义错误消息json对象 [英] Custom error message json object with flask-restful

问题描述

使用 abort()方法(例如

abort(500, message="Fatal error: Pizza the Hutt was found dead earlier today
in the back seat of his stretched limo. Evidently, the notorious gangster
became locked in his car and ate himself to death.")

这将生成以下json输出

This will generate the following json output

{
  "message": "Fatal error: Pizza the Hutt was found dead earlier today
       in the back seat of his stretched limo. Evidently, the notorious gangster
       became locked in his car and ate himself to death.", 
  "status": 500
}

是否可以使用其他成员自定义json输出?例如:

Is there a way to customise the json output with additional members? For example:

{
  "sub_code": 42,
  "action": "redirect:#/Outer/Space"
  "message": "You idiots! These are not them! You've captured their stunt doubles!", 
  "status": 500
}

推荐答案

人们倾向于过度使用 abort()，而实际上，生成自己的错误非常简单.您可以编写一个易于生成自定义错误的函数，以下是与您的JSON匹配的函数:

People tend to overuse abort(), while in fact it is very simple to generate your own errors. You can write a function that generates custom errors easily, here is one that matches your JSON:

def make_error(status_code, sub_code, message, action):
    response = jsonify({
        'status': status_code,
        'sub_code': sub_code,
        'message': message,
        'action': action
    })
    response.status_code = status_code
    return response

然后代替调用 abort():

@route('/')
def my_view_function():
    # ...
    if need_to_return_error:
        return make_error(500, 42, 'You idiots!...', 'redirect...')
    # ...
