推荐答案

我发现错误响应的原因。其实，这是错误的PACKAGE_SECURITY_IDENTIFIER和CLIENT_SECRET。

I found the reason for the error response. In fact it is the wrong PACKAGE_SECURITY_IDENTIFIER and CLIENT_SECRET.

不要输入值。由于相关的ASCII值不同。因此，它始终是更好地复制并直接粘贴。

DO NOT type the values. Because associated ASCII values differ. Therefore it is always better to copy and paste directly.

您可能会得到与简单code段的访问令牌。

You will probably will get the access token with the simple code snippet.
