jq curl vs 本地文件： jq： 错误 <stdin>(在 ：0)： 无法使用字符串"joke"索引字符串

Question

为什么这不起作用：

curl -s http://api.icndb.com/jokes/random/3 | jq '.[] | .joke'
jq: error (at <stdin>:0): Cannot index string with string "joke"

当这是：

jq '.[] | .joke' jokes.json                                   
"Chuck Norris hosting is 101% uptime guaranteed."
"The crossing lights in Chuck Norris's home town say "Die slowly" and "die quickly". They each have a picture of Chuck Norris punching or kicking a pedestrian."
"When in a bar, you can order a drink called a "Chuck Norris". It is also known as a "Bloody Mary", if your name happens to be Mary."

Answer 1

curl -s http://api.icndb.com/jokes/random/3 | jq '.value[].joke'

在这里工作正常。
