Question

我在我的映射目录中定义了这个存根。我正在尝试根据查询参数的值动态返回文件（查询参数和文件名将具有相同的名称）

请参见下面的示例。

{
  "request": {
    "method": "GET",
    "urlPathPattern": "/some/url/locales/en_GB/products",
    "queryParameters": {
      "typeName": {
        "matches": "([A-Za-z]*)"
      }
    }
  },
  "response": {
    "status": 200,
    "bodyFileName" : "{{request.pathSegments.[5]}}",
    "transformers": [
      "response-template"
    ]
  }
}

GET请求类似于

.../some/url/locales/en_GB/products?typeName=blah

在我的__files目录中，我有一个名为blah.json的文件，我希望响应匹配。

我不确定bodyFileName是否正确。 5表示零索引的查询参数的位置。

弄清楚不同的响应模板变量代表什么值并不困难。以下是g

的示例

{
  "request": {
    "method": "GET",
    "urlPathPattern": "/some/url/locales/en_GB/products",
    "queryParameters": {
      "typeName": {
        "matches": "([A-Za-z]*)"
      }
    }
  },
  "response": {
    "status": 200,
    "body" : "request.requestline.pathSegments:\n[0]: {{request.requestLine.pathSegments.[0]}}\n[1]: {{request.requestLine.pathSegments.[1]}}\n[2]: {{request.requestLine.pathSegments.[2]}}\n[3]: {{request.requestLine.pathSegments.[3]}}\n[4]: {{request.requestLine.pathSegments.[4]}}\n[5]: {{request.requestLine.pathSegments.[5]}}\n\nrequest.query.typeName: {{request.query.typeName}}",
    "transformers": [
      "response-template"
    ]
  }
}

并且GET请求http://localhost:8080/some/url/locales/en_GB/products?typeName=test导致以下响应：

request.requestline.pathSegments:
[0]: some
[1]: url
[2]: locales
[3]: en_GB
[4]: products
[5]: 

request.query.typeName: test

考虑到以上几点，您可以看到所寻找的值不是使用request.pathSegments[x]而是使用request.query.typeName检索的。结果如下：

{
  "request": {
    "method": "GET",
    "urlPathPattern": "/some/url/locales/en_GB/products",
    "queryParameters": {
      "typeName": {
        "matches": "([A-Za-z]*)"
      }
    }
  },
  "response": {
    "status": 200,
    "bodyFileName": "{{request.query.typeName}}.json",
    "transformers": [
      "response-template"
    ]
  }
}

根据查询参数动态返回文件
