在JMeter HTTP POST

Question

我正在使用Apache JMeter针对我们开发的应用程序针对RESTFUL API运行一些性能测试。我有一个终点＆＃34; api / create / empListJob＆＃34;，它基本上在MongoDB中添加了一个或多个员工记录。 POST调用的有效负载如下所示：

{
        "employeeList": [
            {
                "first_name": "josh",
                "last_name": "don",
                "age": "25",
                "address": {
                    "street1": "xyz",
                    "street2": "apt-10",
                    "city" : "def",
                    "state" : "CA",
                    "zip" : "95055"
                },
                "deptType": {
                    "deptID": "1",
                    "deptName": "R&D"
                }
            },
            {
                "first_name": "mary",
                "last_name": "jane",
                "age": "22",
                "address": {
                    "street1": "zzz",
                    "street2": "apt-15",
                    "city" : "yyy",
                    "state" : "CA",
                    "zip" : "95054"
                },
                "deptType": {
                    "deptID": "2",
                    "deptName": "HR"
                }
            }
        ]
    }

如您所见，有效负载采用员工数据列表，并且应该至少有一个员工记录。我有一个要求，我希望JMeter线程组有10个线程，这些线程中的每一个都应该对＆＃34; api / create / empListJob＆＃34;进行并发POST。这样，机构有10个独特的员工记录，从而共创造100条记录。我可以参数化有效载荷的最佳方法是什么？

查看JMeter Functions，例如：

• __threadNum() - 返回当前线程（虚拟用户）的数量
• __Random() - 返回给定范围内的随机数
• __RandomString() - 返回指定输入字符的随机字符串
• __UUID() - 返回随机GUID structure

因此，例如，如果您将JSON有效负载更改为：

"employeeList": [
  {
      "first_name": "josh-${__threadNum}",
      "last_name": "don-${__threadNum}",
      "age": "25",
      "address": {
          "street1": "xyz",
          "street2": "apt-10",
          "city" : "def",
          "state" : "CA",
          "zip" : "95055"
      },
      "deptType": {
          "deptID": "1",
          "deptName": "R&D"
      }
  },
  {
      "first_name": "mary-${__threadNum}",
      "last_name": "jane-${__threadNum}",
      "age": "22",
      "address": {
          "street1": "zzz",
          "street2": "apt-15",
          "city" : "yyy",
          "state" : "CA",
          "zip" : "95054"
      },
      "deptType": {
          "deptID": "2",
          "deptName": "HR"
      }
  }
]
}

JMeter将创建：

- `josh-1` for 1st virtual user
- `josh-2` for 2nd virtual usre
- etc.
