我正在尝试获取以下值：

I'm trying to get the value of:

"id": "598a1843-12f0-42ea-819d-944c1e1d6060",
                "name": "Result5",
                "type": "string"

我设法获取值。
现在，我有9个env变量，分别用于id，名称和类型，我想将值传递给它们，而不为每个变量创建设置事件。
env变量是：
varID1到varID9，
varName1到varName9，
varType1到varType9。

I managed a way to get the values. Now, i have 9 env variables for id, name and type and i want to pass the values to them without creating a set event for each. the env variables are: varID1 to varID9, varName1 to varName9, varType1 to varType9.

I'我尝试使用下面的代码，但是名称 varID ='varId'+ k创建的名称（例如，varID1）未在集合中使用。
i无法看到为什么这行不通。

I'm trying the bellow code but the name created by"varID ='varId'+k", e.g varID1 isn´t used on the set. i can´t see why this doesn´t work.

for ( var j = 0; j < test ; j ++ ) {
    var k = j + 1;
    var varID ='varId'+k;
    var varName ='varName'+k;
    var varType ='varType'+k;
    pm.environment.set(varID,  jsonData[key].variables[j].id);
    pm.environment.set(varName, jsonData[key].variables[j].name);
    pm.environment.set(varType, jsonData[key].variables[j].type);
    console.log(varID + " " + jsonData[key].variables[j].id );
    console.log(varName + " " + jsonData[key].variables[j].name);
    console.log(varType + " " + jsonData[key].variables[j].type);               
}

您有建议吗？

推荐答案

这是否可以帮助您实现同一目标？

Would this help you achieve the same thing? It could be cleaner but I think it would be the same.

let idCount = 1
let nameCount = 1
let typeCount = 1
_.each(_.first(pm.response.json()).variables, (arrItem) => {
    pm.environment.set(`varID${idCount ++}`,  arrItem.id);
    pm.environment.set(`varName${nameCount ++}`, arrItem.name);
    pm.environment.set(`varType${typeCount ++}`, arrItem.type);
})

它将存储像这样的变量：

It would store the variables like this:
