如何编写脚本来编辑JSON文件? [英] how to write a script to edit a JSON file?
问题描述
例如,我有一个名为 people.json
的文件。其内容为:
For example I have a file called people.json
. Its content is:
[
{"name": "Paul",
"age": 29,
},
{"name": "Kathy",
"age": 101,
},
{"name": "Paula",
"age": 12,
},
{"name": "Bruce",
"age": 56,
}
]
所以这里我想为每个人添加一个图片链接,例如
so here I wanted to add a picture link for each person for example
[{"name":"Paul",
"age" : 29,
"pic" : "paul.png"
},
{"name": "Kathy",
"age": 101,
"pic" : "kathy.png"
},
{"name": "Paula",
"age": 12,
"pic" : "paula.png"
},
{"name": "Bruce",
"age": 56,
"pic" : "bruce.png"
}
]
如何编写脚本以向每个人添加 pic
键并添加person.name .lowercase +。png作为值?
How do I go about writing a script to add a pic
key into each person and add in a person.name.lowercase + ".png" as a value?
在流程结束时,将编辑people.json并将其保存到硬件而不是内存中。
At the end of the process, the people.json will be edited and saved into the hardware and not memory.
非常感谢。
推荐答案
这是一个完整的程序,用JavaScript(使用node.js),做你想做的事: / p>
Here's a complete program, in JavaScript (using node.js), doing what you want :
fs = require('fs');
var m = JSON.parse(fs.readFileSync('people.json').toString());
m.forEach(function(p){
p.pic = p.name.toLowerCase()+".png";
});
fs.writeFile('people.json', JSON.stringify(m));
作为奖励(包括其他语言的其他回答者),这里有一个固定的输入JSON:
And as a bonus (including for other answerers with other languages), here's a fixed input JSON :
[
{"name":"Paul","age":29},
{"name":"Kathy","age":101},
{"name":"Paula","age":12},
{"name":"Bruce","age":56}
]
