验证架构

Question

我们如何验证书面模式是否有效。

const schema = {
  "properties": {
    "foo": { "add": "string" , "minLenfeffgth": 3, "maxLefngth": 255 }
  }
};

上述架构是根据ajv.validateSchema()的有效架构。

就像我们验证数据一样，任何函数都可以验证架构。

完整代码：

var Ajv = require('ajv');

var ajv = new Ajv({ allErrors: true});

const schema = {
  "properties": {
    "foo": { "add": "string" , "minLenfeffgth": 3, "maxLefngth": 255 }
  }
};

// console.log(ajv.validateSchema(schema));
var validate = ajv.compile(schema);

test({"foo": ""});

function test(data) {
  var valid = validate(data);
  if (valid) console.log('Valid!');
  else console.log(validate.errors);
}

结果是：有效

Answer 1

您可以配置Ajv引发错误并使用from tkinter import * top=Tk() for t in [("1","2","3","4","5"),("aa","bb","cc","dd","ee"),("!@","%^","&*","@#","@$"),("A","B","C","D","E")]: for x in range(4): for y in range(5): w = Text(top, width=15, height=2) w.grid(row=x,column=y) w.insert(END, t[y]) top.state("zoomed") top.mainloop() ：

compile

var ajv = new Ajv({
  allErrors: true
});

var schema = {
  type: 'object',
  properties: {
    date: {
      type: 'unexisting-type'
    }
  }
};

try {
  var validate = ajv.compile(schema);
} catch (e) {
  console.log(e.message);
}

Answer 2

  

上述架构是根据ajv.validateSchema（）的有效架构。

这是有效的，但没有进行任何验证，如果您想使用prefix = prefix or "\some_char" 强制属性来测试一个简单的对象，则可以执行以下操作：

data = {
  point: {
    x: '4.0',
    y: '10.0'
  }
}

startX = 10;
startY = 5;

newX= startX + data.point.x;
newY= startY - data.point.y;

console.log(newX, newY)

foo

运行数据= var ajv = new Ajv({ allErrors: true }); var schema = { "$schema": "http://json-schema.org/draft-07/schema#", "type": "object", "properties": { "foo": { "type": "string", "minLength": 3, "maxLength": 255 } }, "required": [ "foo" ] }; try { var validate = ajv.compile(schema); test({"foo": "" }); } catch (e) { console.log("Validate error :" + e.message); } function test(data) { var valid = validate(data); if (valid) { console.log('Valid!'); } else { console.log(validate.errors); } }返回以下错误消息：

<script src="https://cdnjs.cloudflare.com/ajax/libs/ajv/6.6.2/ajv.min.js"></script>

运行数据= {"foo": "" }返回以下消息：

  

有效！
