推荐答案
当您想将结果保存到变量时,需要引用结果:
You need to quote the result when you want to save it to a variable:
#!/bin/bash
result="$(curl -i -H "Accept: application/json" -H "Content-Type: application/json" https://jsonplaceholder.typicode.com/posts/1)"
echo the result is: "${result}"
双引号很重要如果你想保留多行。
The double quotes are important if you want to preserve multiple lines.
