嗨，這是我的代碼連接到谷歌帳戶來修改日曆，但每次系統響應我「未經授權」。像作爲的accessToken沒有被證實，我不明白的地方的問題

請幫我 感謝很多提前

Answer 1

在最新版本的Java API庫中，用於處理OAuth的機制發生了顯着變化。

你要遵循示例代碼此處引用生成器模式： http://code.google.com/p/google-api-java-client/source/browse/calendar-cmdline-sample/src/main/java/com/google/api/services/samples/calendar/cmdline/CalendarSample.java?repo=samples#57

Credential credential = OAuth2Native.authorize(
    HTTP_TRANSPORT, JSON_FACTORY, new LocalServerReceiver(), 
    Arrays.asList(CalendarScopes.CALENDAR)); 

// set up global Calendar instance 
client = com.google.api.services.calendar.Calendar.builder(HTTP_TRANSPORT, JSON_FACTORY) 
    .setApplicationName("Google-CalendarSample/1.0").setHttpRequestInitializer(credential) 
    .build(); 

這會自動處理提示您（甚至不會在桌面上一些偉大的魔法打開瀏覽器）。或者，如果您正在尋找如何在封底下執行此操作，請在此處提供更多信息： http://code.google.com/p/google-api-java-client/source/browse/shared/shared-sample-cmdline/src/main/java/com/google/api/services/samples/shared/cmdline/oauth2/OAuth2Native.java?repo=samples#102

Answer 2

後您設置您的GoogleAccessProtectedResource對象，你不會傳遞到日曆服務類正確。

更改此：

com.google.api.services.calendar.Calendar service = 
    new com.google.api.services.calendar.Calendar(httpTransport, 
                jsonFactory); 

這樣：

com.google.api.services.calendar.Calendar service = 
    new com.google.api.services.calendar.Calendar(httpTransport, 
                accessProtectedResource, 
                jsonFactory); 

應該這樣做。
