java 通過 microsoft graph 調用outlook

廢話不多說

一 官方文檔

先看一下官方文檔，https://learn.microsoft.com/zh-cn/graph/tutorials/java?context=outlook%2Fcontext&tabs=aad&tutorial-step=1

其中的代碼，可以通過地址下載：https://developer.microsoft.com/en-us/graph/quick-start

 

二 授權方式

microsoft登錄授權方式有很多種，

上面的是OAuth 2.0 授權代碼授予  這個方式

但是這個方式，直接將enter code打印在在控制檯，我沒辦法獲取到（知道的小夥伴可以分享一下）。

因此我換成了 客戶端密碼  方式

 

 

三 代碼示例

官方文檔：https://learn.microsoft.com/zh-cn/entra/identity-platform/quickstart-daemon-app-java-acquire-token#register-and-download-your-quickstart-app

 

1 註冊應用 （官方文檔的step1）https://learn.microsoft.com/zh-cn/graph/tutorials/java?context=outlook%2Fcontext&tabs=aad&tutorial-step=1

 

2 應用授權

進入應用後，API權限--添加權限--選擇權限（我選了Mail.ReadWrite和User.Read.All）

然後管理員點擊 代表xxx授予管理員同意

 

3 獲取應用配置信息

獲取祕鑰

證書和密碼--新客戶端密碼--記錄密碼（密碼只顯示一次，請記錄！），

雖然密碼只顯示一次，但我們可以生成新密碼來獲取新的。
