Question

我正在开发一个iOS应用程序。我在使用iOS中的MKNetwrokingKit库向Java服务器发送“POST”请求时遇到了问题。

我得到的服务器端响应是 -

客户端响应为NSUrlErrorDomain 500

由于

Answer 1

错误500表示它是服务器的内部错误。

这通常意味着服务器遇到异常，可以正确处理您的请求。当服务器未正确编码时，可能会发生这种情况。

但这并不意味着您的请求是“正确的”：让我们假设一个POST请求，您可以在其中发送您的登录名和密码。想象一下，您的请求只发送一个登录名并且服务器编码不正确，并且在使用它之前不检查2个变量是否存在，它将导致NullPointerException（在java中）。

无论如何，你应该与服务人员取得联系，这样他们就可以调试你的请求，看看出了什么问题并纠正它以避免错误500（这不会发生）

同时，看着

java.lang.IllegalArgumentException：No enum const class xtremum.health.us.api.generic.StaticVariable $ ClientType.Praxify_151 / 1.0 CFNetwork / 609 Darwin / 12.2.0

它看起来像一个身份验证错误，也许他们没有为您的请求创建ClientType（或者您忘记正确填写此客户端类型？）

您是否将一些身份验证信息传递给服务器？
