Question

代码似乎没有任何错误。
这是一个测试应用程序，所有ID都可用。
在函数getToken（）中，可以选择取消阻塞行调用 getScopes（）并进一步尝试。
我有一个带按钮的index.jsp。
按下按钮＆＃34; o授权＆＃34;被激活以生成代码和id_token。
我能够登录，生成代码和id_token。
这些值显示在＆＃34; authtoken.jsp＆＃34;它有一个按钮。
按下按钮发布到/common/oauth2/v2.0/token。
在此阶段，Microsoft页面上显示400错误请求。

我不确定出了什么问题：

Answer 1

访问令牌的Microsoft Outlook API端点：https://login.microsoftonline.com/common/oauth2/v2.0/token 期望基于表单的POST，即application / x-www-form-urlencoded。
这意味着所有输入参数都应该基于表单而不是追加网址
从技术上讲，使用UriComponentsBuilder
代码应该使用基于JSON或基于表单的方法，使用HttpClient和HttpPost，或者使用基于OKHttpClient和RequestBody的OKHttp3。

我很快就会在这里发布工作代码。
