在用postman進(jìn)行接口測(cè)試的過(guò)程中，如果接口之間有依賴，那必然涉及到需要把接口的response結(jié)果的值提取出來(lái)給下一個(gè)接口使用。
今天我們就來(lái)講一講如何提取一個(gè)json類型的response里的數(shù)據(jù)。

假設(shè)我們的response如下。

{
    "dateSlots": [
        {
            "date": "2020-07-23",
            "available": true
        },
        {
            "date": "2020-07-24",
            "available": true
        }
    ],
    "timeSlots": [
        {
            "dealerId": "9",
            "advisorId": null,
            "date": "2020-07-23",
            "startTime": "9:00",
            "endTime": "9:30",
            "available": false
        },
        {
            "dealerId": "9",
            "advisorId": "ADV_490_13",
            "date": "2020-07-23",
            "startTime": "13:00",
            "endTime": "13:30",
            "available": true
        },
        {
            "dealerId": "9",
            "advisorId": "ADV_490_13",
            "date": "2020-07-23",
            "startTime": "13:30",
            "endTime": "14:00",
            "available": true
        }
    ]
}

1.提取所有response的值

pm.test("get timeslots", function(){

    var data = pm.response.json();

    console.log(data)

})

2.提取timeSlots里的值

pm.test("get timeslots", function(){

    var data = pm.response.json();

    console.log(data.timeSlots)

})

3.提取第一個(gè)dealerId的值

pm.test("get timeslots", function(){

    var data = pm.response.json();

    console.log(data.timeSlots[0].dealerId)

})

4.遍歷所有的dealerId的值

pm.test("get timeslots", function(){

    var data = pm.response.json();
        
    _.each(data.timeSlots, (result) => {
        console.log(result.dealerId)
    })
})

5.找出所有available為true，dealerId不為null的advisorId的值

pm.test("get timeslots", function(){
    var data = pm.response.json();

    _.each(data.timeSlots, (result) => {
        if(result.available == true && result.advisorId != null){
            console.log(result.advisorId)
        }
    })
})

6.把所有的符合條件5的advisorId存到全局變量

把所有的advisorID存到一個(gè)數(shù)組中，名為advisorIds的全局變量中。
使用JSON.stringify(), 把數(shù)組值作為一個(gè)string存起來(lái)。

    var data = pm.response.json();
    let advisorIds = [];

    _.each(data.timeSlots, (result) => {
        if(result.available == true && result.advisorId != null){
            advisorIds.push(result.advisorId)
        }
    })

    pm.globals.set("advisorIds", JSON.stringify(advisorIds))
