为什么 cURL 认为我正在下载某些内容？

以下是我的 curl 命令：

curl -d "$(curl localhost:8080/fetchStrs)" localhost:8080/uppercase,toChars -H "Content-Type: application/json"

我期望得到回报：

["T","E","S","T","1","T","E","S","T","2"]

但我得到的却是：

  % Total    % Received % Xferd  Average Speed   Time    Time     Time  Current
                             Dload  Upload   Total   Spent    Left  Speed
100    17  100    17    0     0   5666      0 --:--:-- --:--:-- --:--:--  5666
["T","E","S","T","1","T","E","S","T","2"]

为什么 curl 认为我正在下载某些内容？如何删除下载元数据？

没关系，这是一个简单的修复：

curl -d "$(curl -s localhost:8080/fetchStrs)" localhost:8080/uppercase,toChars -H "Content-Type: application/json"

-s会默默地去做。
