空例外：无认证报头信息 - 即使设置.setUserToken（AUTH_TOKEN）

我有以下方法：空例外：无认证报头信息 - 即使设置.setUserToken（AUTH_TOKEN）

public String tryGoogleAuthentication(String auth_token){ 
    ContactsService contactsService = new ContactsService("....."); 
    contactsService.setUserToken(auth_token); 

    IFeed feed = null; 
    try { 
     feed = contactsService.getFeed(new URL("https://www.google.com/m8/feeds/ contacts/default/full?max-results=10000"), ContactFeed.class); 
    } catch (IOException e) { 
     e.printStackTrace(); 
     return CONST.GOOGLE_AUTH_INVALID_TOKEN; 
    } catch (ServiceException e) {   
     e.printStackTrace(); 
     return CONST.GOOGLE_AUTH_INVALID_TOKEN; 
    } catch (NullPointerException e) { 
     e.printStackTrace(); 
     return CONST.GOOGLE_AUTH_INVALID_TOKEN; 
    } 

    if (feed == null) 
     return ""; 

    String externalId = feed.getId(); 
    IPerson person = feed.getAuthors().get(0); 
    String email = person.getEmail(); 
    String name = person.getName(); 
    String nameLang = person.getNameLang(); 

    System.out.println("externalId: " + externalId); 
    System.out.println("email: " + email); 
    System.out.println("name: " + name); 
    System.out.println("nameLang: " + nameLang); 

    return CONST.STATUS_OK; 
}

，我得到的错误：

请告诉一下我768,16设置联系服务（setUserToken除外）才能正常工作？（我是一个android/iPhone开发者） - 我从android设备（通过让用户来确认这个）从auth字符串，并通过一个安全的通道传递给我的服务器 - 现在我想收集关于此联系人的一些数据（首字母，姓氏和提供者uid - 我需要在我的应用中使用带有用户的数据库）。

我真的需要完成这项任务，所以请，如果有人知道如何解决这个问题，请帮助我！

下面的类描述了我从android设备获取auth字符串的方式。

一些额外的空间在这里：'“../feeds/触点/ ...”'，但是这将引发一个‘错误的请求’异常。只有这样，我发现得到一个“无身份验证头信息”异常是使用无效的令牌。 – 2012-03-21 21:38:25

您是如何从Android获取身份验证令牌的？它看起来怎样？ – 2012-03-21 21:46:02

我已经编辑我的问题，用于从Android设备获取身份验证令牌的类。 – 2012-03-22 10:12:23

accountManager.getAuthToken(currentUsedAccount, "ah", false, 
          new GetAuthTokenCallback(), null);

您的帐户类型错误。联系人API范围http://www.google.com/m8/feeds/为v2或https://www.google.com/m8/feeds/为v3

谢谢加百列，你救了我！我已将其更改为：accountManager.getAuthToken（account，“cp”，false， \t \t \t \t new GetAuthTokenCallback（），null）; – 2012-03-26 08:34:12

空例外：无认证报头信息 - 即使设置.setUserToken（AUTH_TOKEN）
