aws 服务器中的 muutanja 错误，而不是 localhost
[英]muutanja error in aws server and not in localhost
问题描述
希望在这里提出这样的问题是有意义的：
我有一个 python3 api，它使用 Flask 来提供服务。 我还有一个 clojure 应用程序，它发出一个针对 python3 api 的 post 请求。 为此，我将clj-http与以下内容一起使用：
(client/post url-link
{:basic-auth ["username"
"password"]
:form-params json
:content-type :json})
现在，当我在本地为 python3 api 提供服务的机器上进行测试时，即，
(def url-link "localhost:port/api-name")
它工作顺利。 问题出现是因为我将从亚马逊服务器提供 python3 api。 所以我的想法是使用亚马逊服务器的链接。 但是当我这样做时，clojure 会抱怨

那么，有没有可能说我做错了什么？ 有没有办法从客户端解决它？
注意：问题是这是我工作的代码，我不想分享其中的很多细节。 我问是因为也许我缺少一个简单的解决方案。 如果这个问题在这里没有意义，请告诉我，我会删除它。
我感谢任何帮助！

我已经弄清楚发生了什么。 亚马逊服务器的python应用程序出现内部错误，所以当它返回到clojure应用程序时，它不知道如何将错误转换为JSON（这是预期的）。 所以解决方案是处理python应用程序中的错误以返回有关该问题的JSON。
在我的本地机器上工作，因为我有所有非 python 依赖项来使应用程序工作。 谢谢您的帮助！
