使用 jq 解析 JSON 错误

Question

I have a curl command which results in the following example json:

json={"id":"12345","key":"ABC-DEF","url":"https://google.com"}

Now, I want to parse this, and get the key out of it and store it in a variable. What I did was the following:

json={"id":"12345","key":"ABC-DEF","url":"https://google.com"}
ID=$(echo $json | jq '.key' )

But the above gives me a error as: parse error: Invalid numeric literal at line 1, column 4 . Can someone help me with this? Thanks!

Answer 1

You will need to quote the input string so the shell doesn't do anything with your string

json='{"id":"12345","key":"ABC-DEF","url":"https://google.com"}'
ID=$(echo "$json" | jq '.key' )
