Question

我有这个json输出，我想确保top_properties不为空。
在top_properties中，键值是动态的，它们不是静态的。那就是我坚持的地方。

  {
  "id": "test",
  "name": "name",
  "cake_name": "test",
  "metric": 0.5,
  "anticipations": [
    {
      "time": "2018-01-01 00:00:00",
      "points": 0.49128797804879504,
      "top_properties": {
        "LA:TB2341": 0.23,
        "LA:TB2342": 0.23,
        "LA:TB2343": 0.23
      },
      "status": 0,
      "alert": false
    }

我具有以下架构，但是当top_properties为空时它不会失败。我想确保它为空时失败。

{

                }
            }
        }
    }
}

由于我没有静态值，因此如何使用模式属性必需的值，如果遇到这种情况，如何实现它。

Answer 1

您想要from matplotlib import pyplot as plt import numpy as np sz=100 x = np.linspace(-1, 1, sz) mean = -np.sign(x) noise = np.random.randn(*x.shape) K = -2 y_true = K*x y = y_true + mean + noise plt.scatter(x, y, label="Data with error") plt.plot(x, y_true, "-", label="True line") plt.grid()关键字https://json-schema.org/understanding-json-schema/reference/object.html#size

例如，

minProperties

如何为json模式的“模式属性”编写“必需”
