Dropbox核心API JAVA授权代码
使用dropbox,我可以上传一个文件 但是,我的问题与此完全相同,即,一旦我有了授权码并注释掉用户授权行,这样我就不必每次使用dropbox时都手动重新授权批准,我会出现以下错误:Dropbox核心API JAVA授权代码,java,connection,dropbox,dropbox-api,Java,Connection,Dropbox,Dropbox Api,使用dropbox,我可以上传一个文件 但是,我的问题与此完全相同,即,一旦我有了授权码并注释掉用户授权行,这样我就不必每次使用dropbox时都手动重新授权批准,我会出现以下错误: Exception in thread "main" com.dropbox.core.DbxException$BadRequest: {"error_description": "code has already been used", "error": "invalid_grant"} 或 我确信我有正确的
Exception in thread "main" com.dropbox.core.DbxException$BadRequest: {"error_description": "code has already been used", "error": "invalid_grant"}
或
我确信我有正确的授权码
我希望我遗漏了一些东西,否则,如果每次使用API时都需要人工干预,那么API有什么意义呢
编辑:我的确切代码(密钥已被置乱)
您应该存储和重用访问令牌,而不是授权代码 所以在做了一次之后:
String accessToken=authFinish.accessToken代码>
你应该把整个东西换成
String accessToken=”“代码>
顺便说一句,如果你只需要一个访问令牌为你自己的帐户,你可以生成一个点击按钮!请参阅。您没有正确使用访问令牌。请粘贴一些有关如何使用令牌的代码。向我们展示整个dropbox代码lines@devaldcool谢谢你的时间,我张贴在编辑下我的代码。
