如何從可執行bash腳本中的curl獲得正確的響應？

Question

我有一個超級簡單的bash腳本...

#!/bin/bash 
result=$(curl -i -H "Accept: application/json" -H "Content-Type: application/json" https://jsonplaceholder.typicode.com/posts/1) 

我試圖調用REST API和解析響應。

當我執行這個腳本，我得到這個反應，這是不是我想要的......

% Total % Received % Xferd Average Speed Time Time  Time Current 
           Dload Upload Total Spent Left Speed 
146 292 146 292 0  0 1106  0 --:--:-- --:--:-- --:--:-- 6790 

當我直視着我的終端上運行curl命令，我得到這個響應，這是什麼我想...

    "body": "quia et suscipit\nsuscipit recusandae consequuntur expedita et cum\nreprehenderit molestiae ut ut quas totam\nnostrum rerum est autem sunt rem eveniet architecto" 
} 

有人能指出我錯過了什麼，請:)

Answer 1

你需要引用的結果，當你想將其保存到一個變量：

#!/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}" 

如果要保留多行，雙引號是很重要的。

Answer 2

要獲得curl的實際輸出，您可以直接在腳本中使用該命令。或者你可以設置終點在一個變量...

#!/bin/bash 
result=https://jsonplaceholder.typicode.com/posts/1 
curl -i -H "Accept: application/json" -H "Content-Type: application/json" $result 

這可以告訴你你想要什麼。
