在用postman进行接口测试的过程中，如果接口之间有依赖，那必然波及到须要把接口的response后果的值提取进去给下一个接口应用。
明天咱们就来讲一讲如何提取一个json类型的response里的数据。
假如咱们的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.提取第一个dealerId的值
pm.test("get timeslots", function(){ var data = pm.response.json(); console.log(data.timeSlots[0].dealerId)})4.遍历所有的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为true，dealerId不为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.把所有的符合条件5的advisorId存到全局变量
把所有的advisorID存到一个数组中，名为advisorIds的全局变量中。
应用JSON.stringify(), 把数组值作为一个string存起来。
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))
