Swift 3 NTLM身份验证

本文介绍了Swift 3 NTLM身份验证的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

对于一个最近的项目，我试图分别从服务器中以SOAP和oData格式提取一些数据，这些数据已通过Microsoft NTLM身份验证进行保护，这真是一场噩梦，想方设法做到这一点，而这一切都不在线例子确实有效.

For a recent project I tried to pull some data from a server in the SOAP and oData format respectively, that is protected with a Microsoft NTLM authentication, and it has been a nightmare figuring out how to do it, none of the online examples really worked.

推荐答案

所以这是我的解决方案；我必须适应，扩展和结合一些不同的资源.我希望这对以后的人有所帮助.

So here is my solution; I had to adapt, expand and combine a few different sources. I hope this helps someone in the future.
