rest - 学习 Clojure : unable to fix

Question

我正在关注一些有关 clojure Rest api 代码示例的博客文章，并发现了这个 -> https://blog.interlinked.org/programming/clojure_rest.html 。但是，当我尝试使用此curl命令发布一些数据时:-
curl -XPOST -d '{"id": "1", "title": "第一个文档", "text": "第一个文档文本"}' http://localhost:3000/documents

，我收到以下异常:-

有人可以帮我解决这个问题吗？
TIA

试试这个:

curl -XPOST -H "Content-Type: application/json" -d '{"id": "1", "title": "First document", "text": "First document text"}' http://localhost:3000/documents
