如何使用Wiremock配置请求匹配规则实现不同petId返回对应响应

• 错误1：JSONPath字段名不匹配，请求体中携带的字段是petId，你的配置中全部误写为petType，导致字段匹配逻辑本身就不成立
• 错误2：JSON对象中存在重复键会被覆盖，你将3个matchesJsonPath规则写在同一个对象内，JSON解析时后定义的键会直接覆盖前面的，所以最终只有最后一个规则（匹配125、252）生效
• 错误3：WireMock中同一bodyPatterns数组内的多个规则默认是与逻辑，需要显式声明才能实现满足任意规则即匹配的效果

你可以直接用JsonPath的in运算符简化多值匹配逻辑，修正后的配置如下：

{
  "mappings": [
    {
      "request": {
        "method": "POST",
        "urlPath": "/mock/animal/status",
        "bodyPatterns": [
          {
            "matchesJsonPath": "$[?(@.petId in ['123','124','125'])]"
          }
        ]
      },
      "response": {
        "status": 200,
        "transformers": ["response-template"],
        "bodyFileName": "animal-success-40-200.json",
        "headers": {
          "Content-Type": "application/json"
        }
      }
    },
    {
      "request": {
        "method": "POST",
        "urlPath": "/mock/animal/status",
        "bodyPatterns": [
          {
            "matchesJsonPath": "$[?(@.petId in ['250','251','252'])]"
          }
        ]
      },
      "response": {
        "status": 200,
        "transformers": ["response-template"],
        "bodyFileName": "animal-success-80-200.json",
        "headers": {
          "Content-Type": "application/json"
        }
      }
    }
  ]
}

如果你想要用多规则声明的写法，也可以按如下格式配置，显式声明或逻辑：

"bodyPatterns": [
  {"matchesJsonPath": "$[?(@.petId == '123')]"},
  {"matchesJsonPath": "$[?(@.petId == '124')]"},
  {"matchesJsonPath": "$[?(@.petId == '125')]"},
  {"expression": "OR"}
]
