如何在Postman测试脚本中的系统响应中包含2个元素的数组中存储值

Question

我正在尝试使用以下代码将"TokenType": "UserAccount"的令牌存储到变量中，但它似乎无法正常工作。请帮助。

我的代码：

if (responseCode.code === 200) {
    try {
        var tokenValue = JSON.parse(responseBody);
    } catch (e) {
        if (e) {
            console.log(e);
        }
    }
}
postman.setGlobalVariable("Acc_Token", tokenValue[0].value);

由标记值组成的数组：

"value": [
    {
        "Expires": "2017-09-05T05:07:11.0778675Z",
        "IsRefreshable": false,

Answer 1

您的value财产不在第一项中。它在对象本身

通过tokenValue.value[0]访问将为您提供"TokenType": "UserAccount"的对象。

并将postman.setGlobalVariable移到if语句中。
