使用SDKiOS将视频发布到Facebook时出错

Question

我有一个应用程序，可以使用Facebook SDK将本机（MOV文件）视频发布到FacebookiOS。它一直运行正常，直到几周前才出现以下错误：

    error =         {
        code = 352;
        message = "(#352) Sorry, the video file you selected is in a format that we don't support.";
        type = OAuthException;
    };

完整的错误字符串是：

error Domain = com . Facebook . SDK Code = 5 "操作无法完成。(com.facebook.sdk错误5。)" UserInfo = 0x1ea 42880 { com . Facebook . SDK:HTTPStatusCode = 400，com . Facebook . SDK:ParsedJSONResponseKey = { body = { error = { code = 352；message = "(#352)抱歉，我们不支持您选择的视频文件的格式。"；type = OAuthException};};代码= 400；headers =({ name = " Access-Control-Allow-Origin "；value = " *}，{ name = " Cache-Control "；value = " no-store "；}，{ name = Connection值=关闭；}，{ name = " Content-Type "；value = " text/JavaScript；charset = UTF-8 "；}，{ name = Expiresvalue = " 2000年1月1日星期六00:00:00 GMT "；}，{ name = Pragmavalue = "无缓存"；}，{ name = " WWW-Authenticate "；value = " OAuth \ " Facebook Platform \ " \ " invalid _ request \ " \ "(# 352)抱歉，我们不支持您选择的视频文件的格式。\"";}，{ name = " x-f b-load mon "；value = "0，30，70 "；} );}，com . Facebook . SDK:ErrorSessionKey =，expiration date:4001-01-01 00:00:00 0000，refresh date:2013-10-15 17:19:33 0000，attempted refresh date:2013-10-24 14:56:54 0000，权限:(" share_item "，email，" user_photos "，" user_videos "，" publish_checkins "，" manage_pages "，" read

我用来发布的代码与此类似:

NSMutableDictionary *params = [NSMutableDictionary dictionaryWithObjectsAndKeys:
                                   videoData,@"video.mov",
                                   @"video/quicktime", @"contentType",
                                   title, @"title",
                                   status, @"description",
                                   nil];

FBRequest* request = [FBRequest requestWithGraphPath:[NSString stringWithFormat:@"%@/videos",@"me"]
                                              parameters:params
                                              HTTPMethod:@"POST"];

    [request setSession:session];

    dispatch_queue_t queue = dispatch_get_global_queue(DISPATCH_QUEUE_PRIORITY_BACKGROUND, 0ul);
    dispatch_async(queue, ^{
        dispatch_async(dispatch_get_main_queue(), ^(void) {

            [request startWithCompletionHandler:^(FBRequestConnection* conn, id data, NSError* error){
                SSLog(@"DONE!");

                [self processResponseWithData:data requestIdentifier:requestIdentifier andError:error];
            }];
        });
    });

我已更新到最新的SDK版本（3.9），但错误仍然存在。任何机构正在经历此错误？

我是用iOS6和iOS7测试的，所以问题与操作系统版本无关。同样的视频使用iOS-脸书内置功能上传okey。

非常感谢！

我不使用key contentType int参数。它与脸书SDK 3.10(最新版本)配合良好

NSData *videoData = [NSData dataWithContentsOfFile:filePath];    
NSString* videoName = [filePath lastPathComponent];
NSMutableDictionary* params = [[NSMutableDictionary alloc] init];
[params setObject:caption forKey:@"description"];
[params setObject:videoData forKey:videoName];

FBRequestConnection *requestConnection = [FBRequestConnection startWithGraphPath:@"me/videos"
                             parameters:params
                             HTTPMethod:@"POST"
                      completionHandler:^(FBRequestConnection *connection, id result, NSError *error)
{

}];

上面的答案有效。但请确保您创建了Facebook会话，使用openActiveSessionWithPublishPerams而不是openActiveSessionWithReadPerams。

我花了一天时间在这上面，因为如果你用错了一个，你会得到著名的“（#352）对不起，你选择的视频文件的格式我们不支持。”

无论如何，您真正需要的唯一权限是publish_actions

就在FB请求之前 添加一行以打开FB请求连接为我工作。

[FBRequestConnection startWithGraphPath:@"me/videos" 
    completionHandler:^(FBRequestConnection *connection, 
    id result, NSError *error) 
{
    FBRequest *uploadRequest = 
        [FBRequest requestWithGraphPath:@"me/videos" 
        parameters:params HTTPMethod:@"POST"];
}];
