【问题描述】：
我想从命令行使用 jq 和 curl 解析 JSON 数据，但我没有成功。事实上，我想得到 response > textAnnotations > description 的值，但我做错了。这是我的命令：
curl -X POST > response.txt \
-H "Content-Type: application/json; charset=utf-8" \
--data "{
'requests': [
{
'image': {
'source': {
'imageUri': 'http://adn-cdn2.avadeo.net/articles/vignettes/grandes/146.jpg'
}
},
'features': [
{
'type': 'TEXT_DETECTION'
}
]
}
]
}" "https://vision.googleapis.com/v1/images:annotate?key=XXXXXXXXXXXXXXXXXXX" | jq -r '.responses.textAnnotations.description'
如果我不使用 JQ 过滤，这是 Curl 的答案：
