Java 原因：org.apache.http.ProtocolException:未指定目标主机，即使其格式不正确

目前，我正在围绕GithubAPI工作。 当尝试使用Apache http api以我的身份验证令牌作为参数发送一个简单的http GET时， 控制台抛出以下命令：

Exception in thread "main" org.apache.http.client.ClientProtocolException
at org.apache.http.impl.client.InternalHttpClient.doExecute(InternalHttpClient.java:186)

是的，我已经阅读了关于这方面的其他问题。但是我修改了它。这是一个完整的URL，因此其他URL无法帮助p

您正在尝试使用httpclient访问

资源。这导致协议错误

访问https URL需要更多的工作，如下所述-

访问https URL需要更多的工作，如下所述- 第25行

HttpGet httpGet = new HttpGet("baseUrl");

HttpGet httpGet = new HttpGet(baseUrl);
