使用 Javascript 函数在邮递员上循环 JSON 响应对象

Question

下面是我对 postman 的 API 请求的 JSON 响应。我希望有一个循环的函数，因为我将在其他请求中使用该函数来根据匹配条件选取某些对象，并在下一个请求中使用它们的属性作为变量。在下面的代码中，我循环遍历响应，如果对象匹配条件，我将其索引推入数组中。我可以从数组中获取对象并在后续请求中使用其参数作为变量。

您的函数存在一些问题，例如 if 的大写不正确以及循环内轴数组的访问不正确。下面是函数的更正版本，以及简化版本，可帮助您循环响应并查找满足条件的对象。

function additionalDayAllowed(jsonData) {
 let permitted_objects = [];
 let number_of_axes = jsonData.axes.length;

 for (let i = 0; i < number_of_axes; i++) {
    let isValidation = jsonData.axes[i].is_validation_required;
    let isAdditional = jsonData.axes[i].additionnal_day_allowed;
    let isRemaining = jsonData.axes[i].remaining_days;
    // Check if the conditions are met
    if (isValidation === false && isAdditional === true && isRemaining > 0) {
        permitted_objects.push(jsonData.axes[i]); // Push the object itself, or 
        use i for index if needed
    }
 }

  return permitted_objects; // Return array of matching objects
}

邮递员中的用法： 要在 Postman 测试中使用此功能：

pm.test("validations", function () {
var jsonData = pm.response.json();
let myExtraDays = additionalDayAllowed(jsonData); // Call your function

   // Check the first permitted object (if any)
   if (myExtraDays.length > 0) {
    console.log("First permitted object:", myExtraDays[0]);
   } else {
    console.log("No matching objects found");
   }
 });
