当结果所在的行返回到客户端时。我以前也说过，排队存钱不太好。我将在代码的这一部分设置try-catch，并发布异常。我看不到您的完整实现，但如果我进行了有根据的猜测，您可能会尝试调用您的登录例程，该例程返回一个HttpResponseMessage数据类型（从您的注册例程中）。这两种方法都使用Request.CreateResponse来创建响应 请看，问题是，您正在尝试序列化已序列化的HttpResponseMessage。您的登录方法将调用Request.CreateResponse来创建HttpResponseMessage，您可能只是将它转过来并“传递”到您的注册方法（但可能会通过另一个Request.CreateResponse方法调用来传递它，这正是您遇到麻烦的地方）。这是一个“隐性”错误，很难抓住——就像一个棋手盯着棋盘看了几个小时 现在来看解决方案： 只需将login方法的结果作为register方法的结果传递，而无需通过Request.CreateResponse方法对其进行“处理”。如果您是Rest返回状态代码的纯粹主义者，您可以在返回Register方法之前首先更改返回的状态代码（因为登录可能有一个OK[200]的状态代码），而在Register Rest end p中返回CREATED[201]是更好的做法
