如何使用 Microsoft Graph API 和 java 获取用户的日历事件
How to fetch calendar events for a user using Microsoft Graph API with java
我希望将个人 Microsoft 帐户 (xyz@hotmail.com) 连接到一个应用程序，然后使用该应用程序获取该帐户的日历事件。
我已经在 Aure 门户中注册了应用程序，我可以使用 Postman 获取事件。这就是我的邮递员配置：
URL: https://graph.microsoft.com/v1.0/me/calendars
Call back URL: https://oauth.pstmn.io/v1/browser-callback
AUTH URL: https://login.microsoftonline.com/consumers/oauth2/v2.0/authorize
Access Token URL: https://login.microsoftonline.com/consumers/oauth2/v2.0/token
Client ID: <Copied from Azure portal>
Client Secret: <Copied from Azure portal>
Scope: https://graph.microsoft.com/.default
Client Authentication: "Send as Basic Auth Header"
如何使用 Java 复制以上内容？请参阅本教程：
https://docs.microsoft.com/en-us/graph/api/calendar-list-events?view=graph-rest-1.0&tabs=java
检查上面的代码 link:
GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider( authProvider ).buildClient();
EventCollectionPage events = graphClient.me().calendar().events()
.buildRequest()
.filter("startsWith(subject,'All')")
.get();
//Read the SDK documentation for details on how to add the SDK to your project and create an authProvider instance.
这是用于创建身份验证提供程序的 link：
https://docs.microsoft.com/en-us/graph/sdks/choose-authentication-providers?tabs=Java
我应该使用哪个提供商？
- 授权码提供商
- 客户端凭据提供程序
- 代表提供商
- 设备代码提供者
等等等等
我无法使上述任何一项工作 -- 我的 java 代码中总是出现太多错误。
我能够实施 OAuth 流程并且有访问令牌和刷新令牌。如何编写 Java 代码来获取日历事件？

我已经在下面提供了我的身份验证提供商代码：
public class GraphAuthenticationProvider extends BaseAuthenticationProvider {
private String accessToken;
public GraphAuthenticationProvider(String accessToken) {
this.accessToken = accessToken;
}
@Override
public CompletableFuture<String> getAuthorizationTokenAsync(URL requestUrl) {
return CompletableFuture.completedFuture(accessToken);
}
}
我是这样使用的：
final GraphAuthenticationProvider graphAuthenticationProvider = new GraphAuthenticationProvider(accessCode);
final GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider(graphAuthenticationProvider).buildClient();
EventCollectionPage events = graphClient.me().calendar().events().buildRequest().get();
这是我得到的错误：

我的访问令牌缺少一个名为：“Calendars.ReadWrite”的范围。这就是应该添加该范围的方式。
AuthorizationCode authorizationCode = new AuthorizationCode(httpServletRequest.getParameter("code"));
String currentUri = httpServletRequest.getRequestURL().toString();
IAuthenticationResult result;
ConfidentialClientApplication app;
try {
app = createClientApplication();
String authCode = authorizationCode.getValue();
Set<String> scopes = new HashSet<String>();
scopes.add("Calendars.ReadWrite"); //see this line
AuthorizationCodeParameters parameters = AuthorizationCodeParameters.builder(authCode, new URI(currentUri)).scopes(scopes)
.build();
Future<IAuthenticationResult> future = app.acquireToken(parameters);
result = future.get();
} catch (ExecutionException e) {
throw e.getCause();
}
if (result == null) {
throw new ServiceUnavailableException("authentication result was null");
}
return result;
然后，应该像这样请求访问令牌：
JWTClaimsSet claims = JWTParser.parse(result.idToken()).getJWTClaimsSet();
String accessToken = result.accessToken();
我希望将个人 Microsoft 帐户 (xyz@hotmail.com) 连接到一个应用程序，然后使用该应用程序获取该帐户的日历事件。
我已经在 Aure 门户中注册了应用程序，我可以使用 Postman 获取事件。这就是我的邮递员配置：
URL: https://graph.microsoft.com/v1.0/me/calendars
Call back URL: https://oauth.pstmn.io/v1/browser-callback
AUTH URL: https://login.microsoftonline.com/consumers/oauth2/v2.0/authorize
Access Token URL: https://login.microsoftonline.com/consumers/oauth2/v2.0/token
Client ID: <Copied from Azure portal>
Client Secret: <Copied from Azure portal>
Scope: https://graph.microsoft.com/.default
Client Authentication: "Send as Basic Auth Header"
如何使用 Java 复制以上内容？请参阅本教程： https://docs.microsoft.com/en-us/graph/api/calendar-list-events?view=graph-rest-1.0&tabs=java
检查上面的代码 link:
GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider( authProvider ).buildClient();
EventCollectionPage events = graphClient.me().calendar().events()
.buildRequest()
.filter("startsWith(subject,'All')")
.get();
//Read the SDK documentation for details on how to add the SDK to your project and create an authProvider instance.
这是用于创建身份验证提供程序的 link： https://docs.microsoft.com/en-us/graph/sdks/choose-authentication-providers?tabs=Java
我应该使用哪个提供商？
- 授权码提供商
- 客户端凭据提供程序
- 代表提供商
- 设备代码提供者 等等等等
我无法使上述任何一项工作 -- 我的 java 代码中总是出现太多错误。
我能够实施 OAuth 流程并且有访问令牌和刷新令牌。如何编写 Java 代码来获取日历事件？
编辑 1
我已经在下面提供了我的身份验证提供商代码：
public class GraphAuthenticationProvider extends BaseAuthenticationProvider {
private String accessToken;
public GraphAuthenticationProvider(String accessToken) {
this.accessToken = accessToken;
}
@Override
public CompletableFuture<String> getAuthorizationTokenAsync(URL requestUrl) {
return CompletableFuture.completedFuture(accessToken);
}
}
我是这样使用的：
final GraphAuthenticationProvider graphAuthenticationProvider = new GraphAuthenticationProvider(accessCode);
final GraphServiceClient graphClient = GraphServiceClient.builder().authenticationProvider(graphAuthenticationProvider).buildClient();
EventCollectionPage events = graphClient.me().calendar().events().buildRequest().get();
这是我得到的错误：

我的访问令牌缺少一个名为：“Calendars.ReadWrite”的范围。这就是应该添加该范围的方式。
AuthorizationCode authorizationCode = new AuthorizationCode(httpServletRequest.getParameter("code"));
String currentUri = httpServletRequest.getRequestURL().toString();
IAuthenticationResult result;
ConfidentialClientApplication app;
try {
app = createClientApplication();
String authCode = authorizationCode.getValue();
Set<String> scopes = new HashSet<String>();
scopes.add("Calendars.ReadWrite"); //see this line
AuthorizationCodeParameters parameters = AuthorizationCodeParameters.builder(authCode, new URI(currentUri)).scopes(scopes)
.build();
Future<IAuthenticationResult> future = app.acquireToken(parameters);
result = future.get();
} catch (ExecutionException e) {
throw e.getCause();
}
if (result == null) {
throw new ServiceUnavailableException("authentication result was null");
}
return result;
然后，应该像这样请求访问令牌：
JWTClaimsSet claims = JWTParser.parse(result.idToken()).getJWTClaimsSet();
String accessToken = result.accessToken();
