javascript - jsonschema-master 验证 json 请求未按预期响应

Question

我正在尝试使用 jsonschema-master 来验证使用 Express 通过 POST 请求输入的 json 请求。请参阅下面的代码和示例。

如果属性标签丢失或拼写错误(例如“model”、“areas”、“id”)，它会拾取，但如果这些属性的值符合规范，则不会拾取。例如，“model”属性被定义为“premium”或“basic”的枚举类型，但我似乎可以将任何旧字符串放在那里，并且无论如何它都会继续，坐标也被定义为类型号，但它再次忽略这一点，然后错误会通过验证器并进一步导致问题。不确定我错过了什么。

node.js 代码:

var Validator = require('jsonschema-master').Validator;
var v = new Validator();
var bodySchema = {
      "model": { 
        "enum": [ "premium","basic" ] 
      },
      "areas": {
        "type":"array",
        "items": {
          "id": {"type": "string"},
          "geometry": {
            "type": { "type":"string"},
            "coordinates": {
               "type":"array",
               "items": {
                 "type":"array",
                 "items": [
                   {"type":"number"},
                   {"type":"number"},
                   {"type":"number"}
                 ]
               }
            },
            "required" : ["type","coordinates"]
          },
          "required" : ["id","geometry"]
        }
      },
      "required" : ["model","areas"]
};
var valResult = v.validate(doc.request, bodySchema);
if (valResult.errors.length) {
  // Validation failed.
  // All processing will now stop.
  console.log('Request invalid: '+ doc._id +" - "+valResult.errors);
}

正确的 JSON 请求示例(在 doc.request 中)

{
  "model": "premium",
  "areas": [
    {
      "id": "1234",
      "geometry": {
        "type": "Polygon",
        "coordinates": [
          [
            [
              453600.0,
              181100.0,
              0
            ],
            [
              453600.0,
              181200.0,
              0
            ],
            [
              453700.0,
              181200.0,
              0
            ],
            [
              453700.0,
              181100.0,
              0
            ],
            [
              453600.0,
              181100.0,
              0
            ]
          ]
        ]
      }
    }
  ]
}

谢谢大家，但我最终还是解决了。以下是该架构的更正语法:

var bodySchema = {
    "type" : "object",
    "properties": {
        "model": { 
            "enum": [ "premium","basic" ] 
        },
        "areas": {
            "type":"array",
            "items": {
                "type" : "object",
                "properties": {
                    "id": {"type": "string"},
                    "geometry": {
                        "type" : "object",
                        "properties": {
                            "type": { "type":"string"},
                            "coordinates": {
                                "type":"array",
                                "items": {
                                    "type":"array",
                                    "items": {
                                        "type":"array",
                                        "items": [
                                            {"type":"number"},
                                            {"type":"number"},
                                            {"type":"number"}
                                        ]
                                    }
                                }
                            }
                        },
                        "required" : ["type","coordinates"]
                    }
                },
                "required" : ["id","geometry"]
            }
        }
    },
    "required" : ["model","areas"]
};
