json 模式不适用于空响应正文

Question

我编写了一种模式来验证响应正文。并将所有项目设置为“必需”。但是当主体返回空数组时，它直到通过，这应该是失败。架构如下：

var schema = {
  "$schema": "http://json-schema.org/draft-04/schema#",
  "type": "array",
  "items": {
    "$ref": "#/definitions/MyObject"
  },
  "definitions": {
    "MyObject": {
      "type": ["object"],
      "properties": {
        "transactionId": "integer",
        "transactionType": "string",
        "bpCode": "string",
        "bpId": "string",
        "postingDate ": "string",
        "dueDate": "string",
        "totalAmount": "number",
        "balanceDue": "number",
        "reconcileAmount": "number",
        "debitCredit": "string",
        "remarks": "string",
      },
      "required": ["transactionId", "transactionType", "bpCode", "bpId", "postingDate", "dueDate", "totalAmount", "balanceDue", "reconcileAmount", "debitCredit", "remarks"],
      "additionalProperties": false
    }
  }
};

tests["Valid respong body schema"] = tv4.validate(data.body, schema);

回复如下：

{
  "errorCode": null,
  "errorMessage": null,
  "body": []
}

Answer 1

您应该使用以下方法排除空数组：

"type": "array",
"minItems": 1
"items": {
  "$ref": "#/definitions/MyObject"
}

给出了正确的答案。你可以试试这个：

const Ajv = require('ajv');
const ajv = new Ajv();

const schema = {
  {
    "$schema": "http://json-schema.org/draft-04/schema#",
        "type": "object",
            "properties": {
        "errorCode": { "type": ["null", "string"] },
        "errorMessage": { "type": ["null", "string"] },
        "body": {
            "type": "array",
                "minItems": 1,
                    "items": {
                "$ref": "#/definitions/MyObject"
            }
        }
    },
    "required": ["errorCode", "errorMessage", "body"],
        "definitions": {
        "MyObject": {
            "type": ["object"],
                "properties": {
                "transactionId": { "type": "integer" },
                "transactionType": { "type": "string" },
                "bpCode": { "type": "string" },
                "bpId": { "type": "string" },
                "postingDate": { "type": "string" },
                "dueDate": { "type": "string" },
                "totalAmount": { "type": "number" },
                "balanceDue": { "type": "number" },
                "reconcileAmount": { "type": "number" },
                "debitCredit": { "type": "string" },
                "remarks": { "type": "string" }
            },
            "required": ["transactionId", "transactionType", "bpCode", "bpId", "postingDate", "dueDate", "totalAmount", "balanceDue", "reconcileAmount", "debitCredit", "remarks"],
                "additionalProperties": false
        }
    }
}
};

const validate = ajv.compile(schema);
const valid = validate(pm.response.json());

if (!valid) {
    console.log(validate.errors);
    pm.test.fail('JSON is invalid');
} else {
    console.log('JSON is valid');
}

希望这能达到预期效果。
