Mountebank

Question

我想在 mountebank 的 POST 请求中存根并检查消息正文，

{
  "port": "22001",
  "protocol": "http",
  "name": "login_user",
  "stubs": [
    {
      "responses": [
        {
          "is": {
            "statusCode": 201,
            "headers": {
              "Content-Type": "application/json"
            },
            "body": {}
          },
          "_behaviors": {
            "wait": 100
          }
        }
      ],
      "predicates": [
        {
          "equals": {
            "path": "/login_user",
            "method": "POST",
            "headers": {
              "Content-Type": "application/json"
            },
            "body": {
              "name": "Tony",
              "age": "20"
            }
          }
        }
      ]
    }
  ]
}

如果邮件正文采用 JSON 格式。预期响应状态代码 200.

例如

{ 
  "body": {
    "name": "Tony",
    "age": "20"
  }
}

如果邮件正文采用 JSON 格式 但 JSON 字符串 。预期响应状态代码 400.

例如

{ 
  "body": "{\"name\": \"Tony\", \"age\": \"20\"}"
}

Answer 1

您可以使用 'matches' 谓词来实现此目的，其中包含一个（在本例中相当粗略）正则表达式以捕获任何字符串输入和 return 一个 400:

  "stubs": [
    {
      "responses": [
        {
          "is": {
            "statusCode": 400,
            "headers": {
              "Content-Type": "application/json"
            },
            "body": {}
          },
          "_behaviors": {
            "wait": 100
          }
        }
      ],
      "predicates": [
        {
          "matches": {
            "path": "/login_user",
            "method": "POST",
            "body": ".*\\\\"name.*"
          }
        }
      ]
    },
    {
      "responses": [
        {
          "is": {
            "statusCode": 201,
            "headers": {
              "Content-Type": "application/json"
            },
            "body": {}
          },
          "_behaviors": {
            "wait": 100
          }
        }
      ],
      "predicates": [
        {
          "equals": {
            "path": "/login_user",
            "method": "POST",
            "headers": {
              "Content-Type": "application/json"
            },
            "body": {
              "name": "Tony",
              "age": "20"
            }
          }
        }
      ]
    }
  ]

或者，您还可以在冒名顶替者声明中指定默认响应代码 400，这样任何与特定谓词不匹配的内容都将 return 默认为 400 响应：

{
  "port": "22001",
  "protocol": "http",
  "name": "login_user",
  "defaultResponse": {
      "statusCode": 400
  },
  "stubs": [
    {
.... snip ....
