Question

我一般都不熟悉Postman和编程/脚本，需要一些帮助来从嵌套数组中检索值，并且还需要验证响应中返回的属性数量。我有以下JSON：

{
    "studentsData":[
        {
            "id": 142,
            "firstName": "Kai",
            "lastName": "Carvalho Rodrigues",
            "addressLine1": "4188 Viking Drive",
            "addressLine2": "",
            "state": "VA",
            "city": "Fairview",
            "postalCode": "43736S",
            "country": "US",
            "emergencyContacts":[
                {
                    "firstName": "Ruby",
                    "lastName": "Wilfred",
                    "phoneNumber": "5541-766-XXXX"
                },
                {
                    "firstName": "Isaac",
                    "lastName": "Jeanneret",
                    "phoneNumber": "5541-761-XXXX"                   
                }         
            ]
        },
        {
            "id": 143,
            "firstName": "Kai",
            "lastName": "Yewen",
            "addressLine1": "4956 Alexander Avenue",
            "addressLine2": "",
            "state": "CO",
            "city": "Denver",
            "postalCode": "94607",
            "country": "US",
            "emergencyContacts":[
                {
                    "firstName": "Matilda",
                    "lastName": "McAdam",
                    "phoneNumber": "988-445-XXXX"
                }
            ]
        }            
    ]
}

我在这里尝试：在studentData下打印名字验证响应中的名字计数打印紧急联系人下的电话号码列表验证响应中的电话号码计数在Postman Console的紧急联系人下打印名字和电话号码。

//打印响应中的所有名字

var jsonData = JSON.parse(responseBody);
var name = jsonData.studentsData;
for (var i = 0; i <= name.length; i++ ) {
console.log(" The list of students' first names are: "+name);

//验证响应中的名字计数

var jsonData = JSON.parse(responseBody);
tests["Total number of students = 2"] = jsonData.studentsData.length === 2;

//打印紧急联系人下的电话号码列表

var responseData = JSON.parse(responseBody);
var i;
var j;
var contactNumbers = jsonData.studentsData[i].emergencyContacts[j];

for (var i = 0; i <= contactNumbers.length; i++ )
    for (var j = 0; j <= contactNumbers.length; j++) {
        console.log(" The list of emergency contacts are: "+contactNumbers);
    }
}

//验证响应中的紧急联系人数

    var jsonData = JSON.parse(responseBody);
    var i;
    var contactNumbers = jsonData.studentsData[i].emergencyContacts[j];
    for (i=0; i <= contactNumbers.length)
       for (var j = 0; j <= contactNumbers.length; j++){
    tests["Total number of emergency contacts = 4"] = jsonData.studentsData[I].emergencyContacts[j].length === 4;
    };

在邮递员控制台中的紧急联系人下打印名字和电话号码-无法解决这种情况

从Postman API中的嵌套响应中检索值
