Question

我遇到了在路由中使用以下代码的问题。

(str "Size " (t/pay-billets-found)) ;-> "Size 2"

（t / pay-billets-found）返回一个整数。

我的路线代码：

(defroutes app-routes
(POST "/upload" []
     {:message (str "a " (t/pay-billets-found))}))

给我这个：

问题是您要返回地图{:message (str "a " (t/pay-billets-found))}

因此，环假设您正在使用状态代码和什么不创建正确的响应对象。

如果你想要回复edn，请改为：

(pr-str {:message (str "a " (t/pay-billets-found))})

如果要正确构建响铃响应，请设置状态和正文：

{:status 200 :body (pr-str {:message (str "a " (t/pay-billets-found))})}

或使用ring.util.response帮助器。
