Wiremock 基于请求的动态响应 - jsonPath 不起作用

Question

我正在独立使用 Wiremock，下面是请求/响应的示例。 jsonPath 不起作用，它正在返回整个代码。我做错了什么？

索取样品

{
    "source": "Web",
    "orders":[ 
        {
            "id": "Order1",
            "status": "In Progress"
        },
        {
            "id": "Order2",            
            "status": "In Progress"
        }
    ]    
}

预期反应

{
    "user": "User1",
    "orders": [
        {
            "id": "Order1",
            "status": "In Progress", 
            "shipping": "Pending"
        },
        {
            "id": "Order2",            
            "status": "In Progress",
            "shipping": "Pending"
        }
    ]
}

我的回复.json

{
    "user": "User1",
    "orders": [
          {{#each (jsonPath request.body '$.batches') as |batches|}}
          {
             "id": "{{{batches.id}}}",
             "status": "In Progress", 
             "shipping": "Pending"
          }{{^last}},{{/last}}
          {{//each}}
    ]
}

实际反应

{
    "user": "User1",
    "orders": [
          {{#each (jsonPath request.body '$.batches') as |batches|}}
          {
             "id": "{{{batches.id}}}",
             "status": "In Progress", 
             "shipping": "Pending"
          }{{^last}},{{/last}}
          {{//each}}
    ]
}

Answer 1

通常，当没有解析任何内容时，这意味着未为此响应启用响应模板。要启用响应模板，您可以通过添加

transformers

字段将其添加到存根映射中：

  "name" : "orders",
  "request" : {
    "url" : "/orders",
    "method" : "GET"
  },
  "response": {
    "status": 200,
    "bodyFileName": "response.json",
    "transformers": [
      "response-template"
    ],
    "headers": {
      "Content-Type": "application/json"
    }
  }
}

使用上面的存根映射和这个

response.json

文件：

{
  "user": "User1", 
  "orders": [ 
    {{#each (jsonPath request.body '$.orders') as |order|}} 
      {
        "id": "{{order.id}}", 
        "status": "In Progress", 
        "shipping": "Pending"
      } {{#not @last}},{{/not}}  
    {{/each}} 
  ]
}

我能够产生您正在寻找的输出。这个要求：

{
  "source": "Web",
  "orders": [
    {
      "id": "Order1",
      "status": "In Progress"
    },
    {
      "id": "Order2",
      "status": "In Progress"
    },
    {
      "id": "Order3",
      "status": "In Progress"
    }
  ]
}

从wiremock产生此输出：

{
  "user": "User1",
  "orders": [
    {
      "id": "Order1",
      "status": "In Progress",
      "shipping": "Pending"
    },
    {
      "id": "Order2",
      "status": "In Progress",
      "shipping": "Pending"
    },
    {
      "id": "Order3",
      "status": "In Progress",
      "shipping": "Pending"
    }
  ]
}

jsonPath

与响应中的数组匹配，并且

each

循环遍历这些元素。

not

检查它是否是循环中的最后一个元素，如果不是，则添加

,

以使响应有效 json。

这里对条件逻辑和迭代有很好的解释 - https://docs.wiremock.io/response-templatating/conditional-logic-and-iteration/

这一切都是使用最新版本的wiremock完成的。
