使用Bash和cURL [英] Working with Bash and cURL

问题描述

我发布了问题

I posted a question here and got an answer that gave me what I needed.

我有一个类似的问题，但是我找不到答案，所以我在问另一个：/

I have a similar problem, but one that I can't find answer for so I'm asking another :/

当我直接在终端中运行以下命令时，通过管道连接到jq时，我会得到正确的响应。

When I run the following command directly in the terminal, I get the correct response when piped into jq.

curl GET "https://jsonplaceholder.typicode.com/posts/2" | jq '.body'

RESPONSE: "*est rerum tempore vitae\nsequi sint nihil reprehenderit dolor beatae ea dolores neque\nfugiat blanditiis voluptate porro vel nihil molestiae ut reiciendis\nqui aperiam non debitis possimus qui neque nisi nulla*"

但是，当我在可执行的bash脚本中运行相同的命令时，看到没有回应？

However, when I run the same command inside an executable bash script, I see no response?

result="$(curl GET https://jsonplaceholder.typicode.com/posts/2)" | jq '.body'
echo "$result"

回显的结果是一个空字符串

The echoed result is an empty string.

请问有人可以指出正确的方向，并用双引号或单引号突出显示某些细微差别吗？我假设我犯了语法错误？

Would someone be able to point me in the right direction please, and possibly highlight some of the nuances with double/single quotations etc? I'm assuming I've making a syntax error?

谢谢

推荐答案

您应该在子外壳中的jq中处理结果。

You should process the results in jq inside the subshell.

result=$(curl GET https://jsonplaceholder.typicode.com/posts/2 | jq '.body')
echo "$result"
