Question

我有一个包含Web服务的Web应用程序。该应用程序在安装了SSL证书的tomcat上运行。该应用程序和Web服务正在运行。如果我尝试通过输入以下内容通过浏览器使用Web服务：

https://myapp:8080/myapp/rest/test/hello

我有一个可以正常工作的XML，它是由我的Web服务生成的。现在，我编写了一个Client应用程序，该应用程序试图使用此Web服务，获取XML并对其进行解析。它加载信任库，获取证书，然后建立SSL握手。按设计工作！

但是，通过尝试向Web服务启动GET请求，我收到了一个空响应。我尝试尽可能多地记录日志，并记录了正在发出的请求：

GET https://myapp:8080/myapp/rest/test/hello返回的响应状态为401未经授权

因为我没有得到任何例外，我的问题是，当我通过浏览器而不是通过代码使用Web服务时，为什么Web服务能正常工作？

遵循我的客户使用的代码：
