通过从另一个视图调用JSON从一个视图获取

问题描述

我有一个返回JSON数据的视图。我想从另一个视图获取数据，所以我尝试从它调用JSON视图。但是，返回了 Response 而不是JSON数据。

  @ app.route（'/ promoters /< int ：id>'，methods = ['GET']）
 def get_promoter（id）：
 ... 
 
>>> get_promoter（3）
<响应440字节[200 OK]> 
  

解决方案

在一个对象取决于它的类型（更多信息这些规则检出）。 json数据存储在 r.response 中，其中 r 是响应 object。

更好的解决方案是创建一个单独的函数，它返回json数据，这个数据可以从两个不同的视图函数中调用。 >

I have a view that returns JSON data. I want to get that data from another view as well, so I tried calling the JSON view from it. However, a Response was returned rather than the JSON data. How can I call one view from another view and get the data?

@app.route('/promoters/<int:id>', methods=['GET'])
def get_promoter(id):
    ...

>>> get_promoter(3)
<Response 440 bytes [200 OK]>

解决方案

The decorator of a view-function can convert your return-value in a Response object depending on it's type (more information about these rules check out here). The json data is stored in r.response where r is the Response object.

The better solution is to create a separate function, which returns the json data, which can be called from two different view-functions.
