我正在使用 AJV 库来验证我的 JSON 模式。我希望能够验证Startdate为字符串。如果不是字符串,则应转换为N/A. 目前,它只转换undefinedN/A.

但是,在这些情况下,它不能按预期工作:

  • null->“空”
  • 0 --> "0"
  • 真——>“真”

如果我希望将上述所有内容转换为N/A字符串,我的 customKeyword 函数会是什么样子?

JSON响应:

jsonResponse: {
  "Issue": {
    "StartDate": "December 17, 1995 03:24:00"
  }
}

架构:

var ajv = new Ajv({
    useDefaults: true,
    coerceTypes: 'undefined'
});

const schema = {
    "type": "object",
    "properties": {
        "Issue": {
            "type": "object",
            "properties": {
                "StartDate": {
                    "type": "string"
                    "default": "N/A",
                    "stringTypeChecker"
                }
            }
        }
    }
}

添加关键字功能:

ajv.addKeyword('stringTypeChecker', {
  modifying: true,
  validate: function(){
    let foo = []
    console.log(foo)
  }
});

var valid = ajv.validate(schema, jsonResponse);

您不需要 coerceTypes 选项。

关键字必须是:

ajv.addKeyword('stringTypeChecker', {
  modifying: true,
  schema: false, // keyword value is not used, can be true
  valid: true, // always validates as true
  validate: function(data, dataPath, parentData, parentDataProperty){
    if (typeof data != 'string' && parentData) // or some other condition
      parentData[parentDataProperty] = 'N/A';
  }
});

架构:

{
  "type": "object",
  "properties": {
    "Issue": {
      "type": "object",
      "properties": {
        "StartDate": {
          "type": "string",
          "default": "N/A",    
          "stringTypeChecker": true
        }
      }
    }
  }
}
