Question

需要从API响应中将Id的值设置为环境变量我尝试了此操作但出现错误 'TypeError | Cannot read property 'DisplayName' of undefined'

我编写了代码，我能够获得DisplayName=Samsung XCover 4的ID，但是无法将ID设置为环境变量。

eval(globals.bigint_fix);    
var jsonData = JSON.parse(responseBody);

for (var i=0; i<=jsonData.Offerings.length; i++)
{
    if(jsonData.Offerings[i].DisplayName === "Samsung XCover 4")
    {
        pm.environment.set("offering", jsonData.Offerings[i].DisplayName.Id);
    }
}

错误：

TypeError |无法读取未定义的属性“ DisplayName”

API响应：

{
    "Offerings": [{
        "Amount": 28592,
        "CurrencyCode": "USD",
        "DisplayName": "Samsung XCover 4",
        "Id": 1910256761716000500,
        "Language": "en-CA",
        "LineOfBusinesses": [
            10048
        ],
        "MarketingViews": [],
        "Name": "Samsung XCover 4",
        "OfferType": 1,
        "ShortDescription": "Offering bundle includes:\n- Airtime"
    }]
}

有两个问题。首先将i<=jsonData.Offerings.length更改为i<jsonData.Offerings.length。其次，这行jsonData.Offerings[i].DisplayName.Id将引发另一个错误，因为DisplayName的值是一个字符串，并且其中没有名称为id的键。

用jsonData.Offerings[i].Id

替换

let jsonData = {
  "Offerings": [{
    "Amount": 28592,
    "CurrencyCode": "USD",
    "DisplayName": "Samsung XCover 4",
    "Id": 1910256761716000500,
    "Language": "en-CA",
    "LineOfBusinesses": [
      10048
    ],
    "MarketingViews": [],
    "Name": "Samsung XCover 4",
    "OfferType": 1,
    "ShortDescription": "Offering bundle includes:\n- Airtime"
  }]
}



for (var i = 0; i < jsonData.Offerings.length; i++) {
  if (jsonData.Offerings[i].DisplayName === "Samsung XCover 4") {
    console.log(jsonData.Offerings[i].Id);
  }
}
