所有的iOS SDK示例都提供了访问邮件、日历、ODfB文件的工作代码，但没有一个示例展示如何访问SharePoint列表项。因此，我正在尝试在Swift中进行简单的REST调用，但一直收到以下错误信息：
[0] (null) @"error_description" : @"不支持的安全令牌。
这是我应用程序启动时代码的一个子集：
[0] (null) @"error_description" : @"不支持的安全令牌。
这是我应用程序启动时代码的一个子集：
var resourceID : String = "https://mytenant.sharepoint.com"
var authorityURL : String = "https://login.windows.net/common/"
var clientID : String = "xxd4200eb-7284-41be-a434-abb269b82f0f"
var redirectURI : NSURL = NSURL(string: "http://www.mycompanywebsite.com")!
override func viewDidLoad() {
super.viewDidLoad()
var defaults: NSUserDefaults = NSUserDefaults.standardUserDefaults()
var er : ADAuthenticationError? = nil
var authContext:ADAuthenticationContext = ADAuthenticationContext(authority: authorityURL, error: &er)
authContext.acquireTokenWithResource(resourceID, clientId: clientID, redirectUri: redirectURI) { (result: ADAuthenticationResult!) -> Void in
if (result.accessToken == nil) {
println("token nil")
} else {
defaults.setObject(result.accessToken, forKey: "accessTokenDefault")
defaults.synchronize()
println("accessToken: \(result.accessToken)")
}
}
}
然后，一旦我获得了令牌，我调用以下代码尝试进行http GET请求但失败：
var resolver : MSODataDefaultDependencyResolver = MSODataDefaultDependencyResolver()
var credentials : MSODataOAuthCredentials = MSODataOAuthCredentials()
var defaults: NSUserDefaults = NSUserDefaults.standardUserDefaults()
credentials.addToken(defaults.objectForKey("accessTokenDefault") as! String)
var credentialsImpl : MSODataCredentialsImpl = MSODataCredentialsImpl()
credentialsImpl.setCredentials(credentials)
resolver.setCredentialsFactory(credentialsImpl)
//build API string to get a sample list info
let request = NSMutableURLRequest(URL: NSURL(string: "https://umaknow.sharepoint.com/_api/web?$select=Title")!)
request.HTTPMethod = "GET"
let token = defaults.stringForKey("accessTokenDefault")
request.setValue("Bearer \(token)", forHTTPHeaderField: "Authorization")
request.setValue("application/json; odata=verbose", forHTTPHeaderField: "accept")
//make the call to the SharePoint REST API
NSURLConnection.sendAsynchronousRequest(request, queue: NSOperationQueue(), completionHandler:{ (response:NSURLResponse!, data: NSData!, error: NSError!) -> Void in
var error:NSError? = nil
let jsonResult: NSDictionary! = NSJSONSerialization.JSONObjectWithData(data, options:NSJSONReadingOptions.MutableContainers, error: &error) as? NSDictionary
if (jsonResult != nil) {
//parse the json into File objects in the table view
let results:NSArray = (jsonResult["d"] as! NSDictionary)["results"] as! NSArray
在这里出现了错误，并提示消息。通过监控网络流量，以下是更详细的情况：

{"error_description":"Unsupported security token."}
显然，我使用提供的令牌方式有问题，但由于我对OAuth2知识的了解非常有限，缺少示例，我感到迷茫。
非常感谢您的任何帮助！
