将文件读入JSON [英] Read files into JSON
问题描述
我想读取几个文件(index.html,style.css,main.js)以创建用于上传的JSON有效负载.
I want to read in several files (index.html, style.css, main.js) to create a JSON payload for upload.
我知道使用nodejs,我可以开始创建自己想要的东西:
I know with nodejs, I can begin to create what I want like so:
var fs = require('fs');
fs.readFile('index.html', 'utf8', function (err, data) {
if (err) throw err;
out = JSON.stringify({"html": data});
console.log(out);
});
尽管我该如何使用 jq 做到这一点?
Though how do I do that with jq?
推荐答案
以下显示了一种处理多个文本文件的方法:
One way to handle multiple text files is illustrated by the following:
(jq -Rs . a.txt ; jq -sR . b.txt) | jq -s
[
"1\n2\n",
"3\n4\n"
]
因此,在您的情况下,您将执行以下操作:
So in your case you would do something like this:
(jq -Rs '{ html: . }' index.html; \
jq -Rs '{ javascript: . }' main.js; \
jq -Rs '{ css: . }' style.css) |\
jq -s add
也就是说,将每个文本文件分别转换为JSON字符串,然后将这些字符串传递给jq.这样做的好处是不需要jq 1.5,但是如果确实有jq 1.5,则使用过滤器inputs
的解决方案可能会更好.
That is, convert each text file to a JSON string separately, and then pipe these strings to jq. This has the advantage of not requiring jq 1.5, but if you do have jq 1.5, then a solution using the filter inputs
might be preferable.
