我正在尝试在 android 应用程序上实现 Spotify SDK，当我单击按钮时，Spotify 活动开始正常，但是当我尝试登录时没有任何反应，它记录了我一个 Unexpected token error，我使用了完全相同的代码就像在 Spotify 教程中一样，希望你能提供帮助

【问题讨论】：

您的 redirect_uri 应该与我在 Spotify 开发者控制台上的应用下提到的 redirect_uri 匹配。

【参考方案1】：

您得到的实际上是JSON.parse() 处的 JSON 错误

如果要解析的字符串不是有效的 JSON，则抛出 SyntaxError 异常。

查看您的代码后，我可以看到您没有完全按照教程进行操作。有说明

MainActivity.java 的完整代码现在应该如下所示，但使用您自己的客户端 ID 和重定向 URI：

因为你的redirect URI 没有设置

private static final String REDIRECT_URI = "yourcustomprotocol://callback";

您的 URI 无法解析。这与您的错误并非巧合，因为在登录过程中使用了重定向 URI，并且基本上是 在成功的帐户授权后客户端将发送到的位置。

现在关于如何设置它，由于我没有使用过 Spotify SDK，所以我帮不了你太多，但你可以使用类似的东西

private static final String REDIRECT_URI = "http://localhost:PORT_NUMBER://authenticationResponse"

PORT_NUMBER 可以是大于 1024 的任何值

有关更多信息，此问题可能会有所帮助：Spotify redirect URI。

希望你能解决这个问题。

【讨论】：

我真的不明白“REDIRECT_URI”，为什么我需要一个本地主机来解析 json？我是否必须创建另一个文件来解析重定向 uri？
