Java google api oauth 2.0 linux根目录

我将GoogleSheetsAPI用于一个Web应用程序，该应用程序将excel工作表可视化为一个图表。如果我在本地运行服务器并使用浏览器访问谷歌同意屏幕，这将非常有效

但是如果我将网页上传到我的linux根服务器，在那里我只能访问控制台，我就不能使用浏览器让机器访问google api

我使用GoogleAPI java示例编写了这段代码

我现在的问题是：如何让我的Web服务器访问google API，我尝试了服务帐户，但如果我使用从服务帐户获得的json作为客户端/机密，它根本不起作用

这是我的密码。也许这是一个简单的解决办法，我只是愚蠢地看到

这不知怎的奏效了。我确信我以前已经用json文件+服务帐户尝试过了，但我可能在以后的某个地方犯了一个小错误。

我还尝试将我的主帐户的访问权限传递给服务帐户，但这也不起作用，或者我在某个地方出错了。我现在也向服务帐户添加了所需的访问权限。经过12个小时的故障排除，它现在可以正常工作。

问题在于谷歌API的AuthorizationCodeInstalledApp类

AuthorizationCodeInstalledApp的浏览方法包含以下代码：

public static void browse(String url) {
    Preconditions.checkNotNull(url);
    // Ask user to open in their browser using copy-paste
    System.out.println("Please open the following address in your browser:");
    System.out.println("  " + url);

它在控制台上打印URL，而不是在日志文件中

---

检查控制台日志/catalina.out日志。将打印相同的行，然后您可以继续此操作。

您是否收到任何类型的错误消息？已发布更新。我仍然不知道我所有的问题在哪里，或者我到底做错了什么，在哪里，但它正在起作用。谢谢回复！

public static void browse(String url) {
    Preconditions.checkNotNull(url);
    // Ask user to open in their browser using copy-paste
    System.out.println("Please open the following address in your browser:");
    System.out.println("  " + url);
