Dropbox在iPhone應用程序中的集成錯誤400

Question

我正在使用名為GSDropboxDemoApp的優秀源代碼，它很好地將Dropbox集成到應用程序中。 但是，在將應用程序鏈接到Dropbox之后，它在加載文件夾內容時出錯。 以下是代碼

我已經編輯了info.plist

- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
#warning Potentially incomplete method implementation. Fill in your Dropbox credentials!
#warning NB: you must also update the URL scheme listed under the CFBundleURLTypes key in GSDropboxDemoApp-Info.plist
    NSString *dropboxAppKey = @"sxxxxxxxxxx";
    NSString *dropboxAppSecret = @"cxxxxxxxxx";
    NSString *dropboxRoot = @"kDBRootAppFolder";  // either kDBRootAppFolder or kDBRootDropbox

    DBSession* dbSession = [[DBSession alloc] initWithAppKey:dropboxAppKey
                                                   appSecret:dropboxAppSecret
                                                        root:dropboxRoot];
    [DBSession setSharedSession:dbSession];

    self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
    // Override point for customization after application launch.
    self.viewController = [[GSViewController alloc] initWithNibName:@"GSViewController" bundle:nil];
    self.window.rootViewController = self.viewController;
    [self.window makeKeyAndVisible];
    return YES;
}

- (BOOL)application:(UIApplication *)application openURL:(NSURL *)url sourceApplication:(NSString *)sourceApplication annotation:(id)annotation
{
    if ([[DBSession sharedSession] handleOpenURL:url]) {
        if ([[DBSession sharedSession] isLinked]) {
            NSLog(@"App linked to Dropbox successfully");
        } else {
            NSLog(@"App not linked to Dropbox!");
        }
        return YES;
    }
    return NO;
}

錯誤信息

 GSDropboxDemoApp[4674:907] [WARNING] DropboxSDK: error making request to /1/metadata/kDBRootAppFolder - (400) Expected a root of either 'dropbox' or 'sandbox', got 'kDBRootAppFolder'

Answer 1

您應該使用常量 ，如下所示：

NSString *dropboxRoot = kDBRootAppFolder;  // either kDBRootAppFolder or kDBRootDropbox

使用常量，這樣您就不必擔心實際值本身。

Answer 2

對於我們這些（未來偶然發現這個問題）使用ruby運動獲得相同的錯誤，它需要是：

dropboxRoot = KDBRootAppFolder # Capital K
