希望在这里提出这样一个问题是有意义的：

我有一个python3 api，它使用它来提供服务。我还有一个clojure应用程序，它可以针对python3 api发出post请求。要做到这一点，我将clj-http与以下内容一起使用：

代码语言：javascript
运行
复制
(client/post url-link
             {:basic-auth ["username"
                           "password"]
              :form-params json
              :content-type :json})

现在，当我在本地服务于python3 api的机器上进行测试时，即，

代码语言：javascript
运行
复制
(def url-link "localhost:port/api-name")

它运行得很顺利。这个问题的出现是因为我将从amazon为python3 api提供服务。所以我的想法是使用亚马逊服务器的链接。但是当我这样做的时候，clojure会抱怨

代码语言：javascript
运行

那么，你能说出我做错了什么吗？有办法从客户端解决这个问题吗？

注意：，问题是这是我工作中的代码，我不想分享其中的很多细节。我之所以问这个问题，是因为我错过了一个简单的解决方案。如果这个问题在这里没有意义，请让我知道，我会删除它。

我很感激你的帮助！

我已经弄清楚了发生了什么。在amazon服务器中的python应用程序中有一个内部错误，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)。因此，解决方案是处理python应用程序中的错误，以返回有关问题的JSON。

在我的本地机器上工作，因为我有所有的非python依赖使应用程序工作。谢谢你的帮助！
