我正在尝试在我的远程 Linux Amazon AMI 服务器上运行 Java .jar 文件。在本地，当我运行此 Java 项目时，会建立永久的 HTTP 连接，并且一切都按预期工作。但是，如果我在我的服务器上运行它，我会收到身份验证错误。我必须通过OAuth1进行身份验证才能访问Twitter的服务器，该服务器在我的本地计算机上完美运行。我是否必须在我的服务器上安装一些东西才能支持 OAuth 或类似的东西？

它与您的计算机时钟同步有关。 如果在日期和时间首选项上使用 MAC，请选择"自动设置日期和时间"。这为我解决了问题。
如果在 Linux 上，请按照以下安装"ntp"的链接进行操作
