【问题描述】:
我正在尝试在 NetBeans 8.2 上运行 QuickStart.java https://developers.google.com/sheets/api/quickstart/java。我已导入所有 Google 库,但遇到了这个问题
Exception in thread "main" java.lang.IllegalArgumentException

【问题讨论】:
-
您链接的那个问题与您自己的问题完全无关 - 您是否阅读了您收到的错误消息,而不是他们收到的内容?鉴于您的错误,您将错误的参数传递给
GoogleAuthorizationCodeFlow.Builder。你的论点正确吗?具体来说,您的 GoogleClientSecrets 存在问题。 -
@tehhowch 是的,我将正确的参数传递给
GoogleAuthorizationCodeFlow.Builder,我不知道如何修复错误,这就是我在这里发布它的原因。我做了很多研究,一无所获。 -
你做了哪些调试步骤?当您将流程构建器拆分为多个步骤(首先创建构建器,然后调用构建器方法,然后构建)时,哪一个给出了错误?您的
client_secrets文件格式是否正确? -
@tehhowch 我只是从 google API 页面下载了
client_secrets.json,然后按照步骤操作。它应该工作 -
当某些东西“应该起作用”但不起作用时,您必须进行调试。错误消息表明特定函数存在非法参数。因此,您的任务是验证(而不是假设)您的输入是必需的。如果您使用的是通用文件,而不是包含应用程序独有的特定信息的文件,那将是您所犯的错误。
