表达式{headers：headers}的评估结果是什么？(What does the expression {headers : headers} evaluate to?)

表达式{headers：headers}的评估结果是什么？(What does the expression {headers : headers} evaluate to?)

我正在阅读tut-spring-security-and-angular-js教程 ，它包含以下表达式：

$http.get('user', {headers : headers}).then(function(response)

{headers : headers}表达式评估的内容是什么？

TIA，Ole

I'm reading through a tut-spring-security-and-angular-js Tutorial and it contains the following expression line:

$http.get('user', {headers : headers}).then(function(response)

What does the {headers : headers} expression evaluate to?

TIA, Ole

最满意答案

它是一个对象文字，其中一个等于whateever的propetry headers存储在变量命名headers 。

一个更容易理解的例子：

var someValue = "aaa"; var myObject = { someKey: someValue }; var headers = "abcdef"; var secondParameter = { headers: headers }; $.get("...", secondParameter);

It's an object literal with one propetry headers equal to whateever is stored under variable named headers.

A little easier to understand example:

var someValue = "aaa"; var myObject = { someKey: someValue }; var headers = "abcdef"; var secondParameter = { headers: headers }; $.get("...", secondParameter);
