Java 通过在restlet中设置安全连接的凭据来获取json响应

这是我能拥有的最简单的代码：

ClientResource resource = new  ClientResource("https://www.myTestSite.com/requests");
resource.setChallengeResponse(ChallengeScheme.
HTTP_BASIC, "kladhfklahghlsgkagdkh", "jgasdkjbvjkagjhgajkb");
// Send the request
try {
resource.get();
} catch (ResourceException re) {
}
// Should be 200
System.out.println(resource.getStatus());

• 我可以在中找到URL（） Firefox，然后要求输入用户名和密码。我把它装满，然后 获取json响应
• 我还可以使用curl命令获得json响应

  curl-u kladhfklahglsgkagdkh:jgasdkjbvjkaggajkb-X GEThttps://www.myTestSite.com/requests

因此，它通过浏览器和curl工作，但不使用restlet
