Python：用于验证模式和自定义错误消息的jsonschema包

{
    "type": "object","properties": {
        "account": {
            "type": "object","required": ["id"],"properties": {
                "id": {"type": "number"}
            }
        },"name": {"type": "string"},"trigger": {

            }
        },"content": {

我正在尝试使用jsonschema.Draft4Validator来验证POSTed JSON对象以检查其有效性,但我在尝试从返回的错误中提出更好的人类可读消息时遇到了一些问题.

以下是我的验证方式：

from jsonschema import Draft4Validator

v = Draft4Validator(self.schema)
errors = sorted(v.iter_errors(autoresponder_workflow),key=lambda e: e.path)

if errors:
    print(','.join(
        '%s %s %s' % (error.path.popleft(),error.path.pop(),error.message) for error in errors
    ))

错误消息如下所示：

内容电子邮件[]太短,触发类型无类型为u’string’

我试图创建一个看起来更像的错误消息请在您的工作流程中添加至少一封电子邮件,“”请确保您的所有电子邮件都包含主题行,“等
