【问题描述】：

我正在使用邮递员进行 API 测试。我的回复信息是

[
    {
        "firstName": "Jia",
        "lastName": "Tes",
        "memberId": 745794,
        "branchId": 12442,
        "branchName": "NZ - Clubware Mobile Test Branch 1"
    },
    {
        "firstName": "Jia",
        "lastName": "Test2",
        "memberId": 745746,
        "branchId": 12442,
        "branchName": "NZ - Clubware Mobile Test Branch 1"
    },
    {
        "firstName": "Jia",
        "lastName": "Test3",
        "memberId": 745748,
        "branchId": 12443,
        "branchName": "Clubware Mobile Test Branch 2 (Pub)"
    },
    {
        "firstName": "Jia",
        "lastName": "Test3",
        "memberId": 745745,
        "branchId": 12442,
        "branchName": "NZ - Clubware Mobile Test Branch 1"
    }
]

我想获取“memberId”，其中“firstName”：“Jia”，“lastName”：“Test3”和“branchName”：“NZ - Clubware Mobile Test Branch 1”

我现在的代码是这样的

var response = JSON.parse(responseBody);
console.log("BODY:" + response[3].memberId);

但是我不喜欢使用索引来定位列表中的元素，我该怎么做呢，谢谢大家！！

【问题讨论】：

尝试response.find(e => e.firstName === 'Jia' && e.lastName === 'Test3' && ... etc).memberId - 了解更多关于数组查找方法read the documentation
@JaromandaX，非常感谢，你的建议很棒！

【解决方案1】：

如果您只想检查特定值，可以使用_.find() Lodash 函数来获取memberId 值：

var user = _.find(pm.response.json(), { 
    firstName: "Jia", 
    lastName: "Test3", 
    branchName: "NZ - Clubware Mobile Test Branch 1" 
})
console.log(user.memberId)

var response = [    {
        "firstName": "Jia",
        "lastName": "Tes",
        "memberId": 745794,
        "branchId": 12442,
        "branchName": "NZ - Clubware Mobile Test Branch 1"
    },
    {
        "firstName": "Jia",
        "lastName": "Test2",
        "memberId": 745746,
        "branchId": 12442,
        "branchName": "NZ - Clubware Mobile Test Branch 1"
    },
    {
        "firstName": "Jia",
        "lastName": "Test3",
        "memberId": 745748,
        "branchId": 12443,
        "branchName": "Clubware Mobile Test Branch 2 (Pub)"
    },
    {
        "firstName": "Jia",
        "lastName": "Test3",
        "memberId": 745745,
        "branchId": 12442,
        "branchName": "NZ - Clubware Mobile Test Branch 1"
    }
]; var i;

for(i =0; i <response.length ; i++)
{ 
  if(response[i].firstName == 'Jia' && response[i].lastName == 'Test3' 
     && response[i].branchName == 'NZ - Clubware Mobile Test Branch 1')
  {
    console.log(response[i].memberId);
  }
}
