[当我尝试使用调试器时，我的代码的每一行都能完美执行，但是我得到的错误代码为400，作为响应代码，我没有遇到什么问题，谁能帮助我找出我的错误。这是我的第一个stackoverflow问题，如果格式错误，我将非常抱歉。
400错误的请求响应状态代码表示服务器由于某些原因（例如格式错误的请求语法，无效的请求消息框架或欺骗性的请求路由）而被视为客户端错误，因此服务器无法或不会处理该请求。其他错误消息指出了400错误的原因。请参阅https://airbrake.io/blog/http-errors/400-bad-request。如果您的请求很复杂，请通过简单的请求进行简化或测试，如果可以，请逐步添加到您的请求中。希望对您有所帮助。
