在jq中将字符串转换为json [英] Convert string to json in jq
问题描述
我有一个json文件,其中包含一个对象内的json字符串:
I have a json file that contains a string of json within an object:
{
"requestType": "POST",
"response": {
"size": 78,
"text": "{\"recordID\":123, \"title\":\"Hello World\", \"content\":\"Lorem ipsum...\"}"
}
}
我需要使用json命令行中介程序 jq .
I need to interperet the contents of the .response.text
string as json using the json command line interpereter, jq.
当我运行此命令时:
jq '.response.text | @json'
输出:"\"{\\\"recordID\\\":123, \\\"title\\\":\\\"Hello World\\\", \\\"content\\\":\\\"Lorem ipsum...\\\"}\""
我得到了一些奇怪的转义json字符串,而不是我可以通过类似以下方式访问的json:.response.text | @json | .recordID
.
I get some weird escaped json string instead of json that I can access via something like this: .response.text | @json | .recordID
.
我意识到@json
函数将使用json并输出json转义的字符串,因此必须有另一种方法,但是@text
似乎没有任何作用.
I realize that the @json
function will take json and output a json escaped string, so there must be another way, but @text
doesn't seem to do anything.
是否有某种方法可以将转义的json字符串转换为我可以使用以下命令解析的实际json:jq '.response.text | @json | .title'
并获得以下输出:"Hello World"
?
Is there some way to convert a string of escaped json to actual json that I can parse with a command such as this: jq '.response.text | @json | .title'
and get this output: "Hello World"
?
推荐答案
它将字符串解析为适当的json值. tojson
(和@json
)则相反,并获取一个json值并将其转换为字符串.
It parses a string to its appropriate json value. tojson
(and @json
) goes the other way around and takes a json value and converts it to a string.
所以您可以这样做:
.response.text | fromjson.title
