英文:
how to send undefined value in postman?
问题
{
"a": [undefined, {"b": "ball", "c": "cat"}]
}
英文:
Is there a way to send something like this in postman?
{
"a": [undefined, {"b":"ball", "c":"cat"}]
}
Postman gives a red underline under undefined. If I use the pre-request script to pm.variables.set('undefinedVariable', undefined); and use this, then my code is giving this error
{
"statusCode": 400,
"error": "Bad Request",
"message": "Invalid request payload JSON format"
}

与node.js或postman无关。 undefined 不是一个有效的JSON值，尽管在JavaScript中是有效的。 你可能可以使用null来代替。
来自官方JSON标准(ECMA-404，第5节)的说明：
undefined 不是一个有效的JSON值，尽管在JavaScript中是有效的。
一个JSON值可以是对象、数组、数字、字符串、true、false或null。
英文:
It has nothing to do with node.js nor postman. undefined is not a valid json value even though it is valid in javascript. You may be able to use null instead

你需要在JSON中使用null代替undefined，因为JSON不支持undefined关键字。示例：
{
"a": [null, {"b": "ball", "c": "cat"}]
}
英文:
You need to define null in place of undefined as JSON doesn't handle undefined keyword. Example:
{
"a": [null, {"b":"ball", "c":"cat"}]
}
