Postman：从JSON Array获取数组值并将它们设置为postman变量

Question

我有同样的问题

postman get values from array and set it,dynamically ,on env variables

但我无法找到如何为自己修改最佳答案的方法。

JSON：

我试图获得response.venues.id的值，有时我最终必须手动创建29个变量。

如果有人可以告诉我如何编辑此代码以使用我的JSON响应，这将是很好的。

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);

})

Answer 1

您可以使用以下内容替换现有脚本：

let responseBody = pm.response.json(),
  venues = _.get(responseBody, 'response.venues');

_.forEach(venues, (venue, index) => {
    pm.environment.set(`varID${++index}`,  venue.id);
});

这会将所有id作为变量存储在环境中，这将显示如下：

说明：

首先，我们从你的响应体中获取venues，以便轻松地对其进行循环。然后我们只对数组中的项运行一个简单的forEach循环，并将每个数组项的相应ID存储在环境变量中。

我们正在使用lodash library来实现_.get and _.forEach这样内置于邮递员的功能。
