json_decode
The json_decode
function decodes a string representing JSON into an Alloy value.
json_decode
fails if the string argument provided can’t be parsed as JSON.
A common use case of json_decode
is to decode the output of a local.file
component to an Alloy value.
Remember to escape double quotes when passing JSON string literals to
json_decode
.For example, the JSON value
{"key": "value"}
is properly represented by the string"{\"key\": \"value\"}"
.
Examples
> json_decode("15")
15
> json_decode("[1, 2, 3]")
[1, 2, 3]
> json_decode("null")
null
> json_decode("{\"key\": \"value\"}")
{
key = "value",
}
> json_decode(local.file.some_file.content)
"Hello, world!"
