验证特定字符串在响应正文中是否可用

Question

响应数据包含类似这样的内容。 "INBOUND_MESSAGE:

HTTP/1.1 200 内容类型：application/json 传输编码：分块 Date:Fri，2017 年 9 月 22 日 12:18:50 格林威治标准时间

{"errors":{"deviceId":{"message":"Path `deviceId` is required.","name":"ValidatorError","properties": {"type":"required","message":"Path `{PATH}` is required.","path":"deviceId","value":""},"kind":"required","path":"deviceId","value":"","$isValidatorError":true},"name":{"message" :"Path `name` is required.","name":"ValidatorError","properties":{"type":"required","message":"Path `{PATH}` is required.", "path":"name","value":""},"kind":"required","path":"name","value":"","$isValidatorError":true}},"_message":"devices validation failed","message":"devices validation failed: deviceId: Path `deviceId` is required., name: Path `name` is required.","name":"ValidationError"}

"

我需要查看我是否可以针对 $.Message 进行验证并且条件必须是 "deviceId` is required"。我使用了下面的代码，但是测试用例失败了，因为 $.Message

上有多个消息可用

            http()
                .client(IotDevice)
                .receive()
                .response(HttpStatus.OK)
                .validate("$.message", "Path `deviceId` is required.");

有没有办法在响应消息中搜索预期的字符串。

对JSON路径的澄清

通过使用 JSON路径表达式 $.message，您不是 selecting 多个 message 条目，但正是一个在根目录下（你可以 select 都使用 $..message，有两个点）。

如果以格式化的方式查看您的 JSON 数据，您可以立即看到最顶部 message 条目的值是 devices validation failed: deviceId: Path deviceId is required., name: Path name is required.，这似乎是errors 部分中的所有消息。

解决方案

因此，如果您的目标是验证字符串 Path deviceId is required 是最顶层 message 条目的一部分，您可以将以下 Citrus 匹配器与 JSON路径表达式（另请参阅 JSONPath and validation matchers 上的 Citrus 文档）：

<message type="json">
  <validate>
    <json-path expression="$.message" value="@contains('Path deviceId is required')@"/>
  </validate>
</message>

格式化JSON

{
  "errors": {
    "deviceId": {
      "message": "Path deviceId is required.",
      "name": "ValidatorError",
      "properties": {
        "type": "required",
        "message": "Path {PATH} is required.",
        "path": "deviceId",
        "value": ""
      },
      "kind": "required",
      "path": "deviceId",
      "value": "",
      "$isValidatorError": true
    },
    "name": {
      "message": "Path name is required.",
      "name": "ValidatorError",
      "properties": {
        "type": "required",
        "message": "Path {PATH} is required.",
        "path": "name",
        "value": ""
      },
      "kind": "required",
      "path": "name",
      "value": "",
      "$isValidatorError": true
    }
  },
  "_message": "devices validation failed",
  "message": "devices validation failed: deviceId: Path deviceId is required., name: Path name is required.",
  "name": "ValidationError"
}
