[英]node.js require of a json file
I am trying to require() this JSON file. 我正在尝试require()这个JSON文件。
{
"info" : function (request) {
var i = "<pre>";
i+= "current working directory: " + process.cwd() + "\n";
i+="request url: " + request.url + "\n";
i+= "</pre>";
return i;
}
}
Using this line 使用这条线
var render = require('./render.json');
But I get an exception from the JSON file of : Unexpected token u 但是我从JSON文件中得到一个异常:意外令牌u
What am I doing wrong please ? 请问我做错了什么?
The following works in a browser. 以下在浏览器中有效。 Which I would expect, since a function is a object.
我会期望的,因为函数是对象。 And nodejs docs suggests JSON can be a module: http://nodejs.org/api/modules.html#modules_file_modules
并且nodejs文档建议JSON可以是一个模块: http ://nodejs.org/api/modules.html#modules_file_modules
<html>
<head>
</head>
<body>
<script>
var a = {
"b" : function(msg){
alert(msg);
}
}
a.b("Hello");
</script>
</body>
</html>
JSON is purely meant to be a data description language. JSON纯粹是一种数据描述语言。 Per http://www.json.org , it is a "lightweight data-interchange format."
根据http://www.json.org ,它是“轻量级数据交换格式”。 - not a programming language.
-不是编程语言。
you cannot have function inside your JSON and use node. 您不能在JSON中使用函数并使用节点。
{
"error": [
function (request) {
}
]
}
Is it valid to define functions in JSON results? 在JSON结果中定义函数是否有效?
The way I have gotten around this is to create a js file instead of a json file: 我解决这个问题的方法是创建一个js文件而不是json文件:
config.js config.js
exports.config = [
{
"foo": 12,
"bar": 10,
"baz": function(a){
console.dir(a);
}
}
]
then within node: 然后在节点内:
config = require('./config.js').config;
var a = {
m: 'something',
o: 'somethingelses'
}
config[0].baz(a);
