let response = pm.response.json();
console.log('JSON Response: ',response );
Then, I opened up my Postman console, before hit Sendto make my POST request
然后，我打开了我的 Postman 控制台，然后点击Send发出我的 POST 请求
I kept getting
我一直得到
There was an error in evaluating the Pre-request Script: TypeError: Cannot read property 'json' of undefined
评估预请求脚本时出错：TypeError：无法读取未定义的属性“json”
Do I need to enable anything on Postman?
我需要在 Postman 上启用任何东西吗？
回答by Clint
Pre-request scripts are ran before the request is sent. You do not have a response yet.
在发送请求之前运行预请求脚本。您还没有回复。
Try putting your script under the Teststab, which is ran after a response is received.
尝试将您的脚本放在Tests选项卡下，该选项卡在收到响应后运行。

In my case, there was a script that was screwing up my request. If you get the postman collection from someone else, check this and try to fix it. (in my case I don't need it so I deleted it)
就我而言，有一个脚本搞砸了我的请求。如果您从其他人那里获得邮递员集合，请检查此并尝试修复它。（就我而言，我不需要它，所以我删除了它）
