使用 Azure 媒体服务获取访问令牌时遇到问题

Question

我正在使用 Azure 媒体服务在 Android 上开发流媒体应用程序。我按照他们页面上的说明进行操作（不能 post 超过 2 个链接）。这是我得到的回复：

D/OkHttp: --> POST https://wamsprodglobal001acs.accesscontrol.windows.net/v2/OAuth2-13 http/1.1

D/OkHttp: <-- END HTTP (254-byte body)

也尝试使用 Postman 发送相同的请求并成功收到令牌。

如果有人遇到同样的问题，我在 Android 应用程序上使用了 Retrofit。问题是因为请求的 @Body 是 String 类型，所以需要正确格式化。这是关于如何操作的 link：https://futurestud.io/tutorials/retrofit-2-how-to-send-plain-text-request-body
