通过iOS App在Twitter上分享video

是否有可能使用SLRequest共享video？

我可以使用相同的图像分享图像 

SLRequest *postRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:requestURL parameters:message]; if (isImage) { NSData *data = UIImagePNGRepresentation(imgSelected); [postRequest addMultipartData:data withName:@"media" type:@"image/png" filename:@"TestImage.png"]; } postRequest.account = account; [postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { if (!error) { NSLog(@"Upload Sucess !"); } }];

我一直在阅读Twitter的video上传API文档，它非常简单。 你基本上需要做3个POST请求到他们的API。 您上传的video也限制在15 MB的大小。

使用此端点上传需要至less3个调用，一个初始化请求，返回media_id，一个或多个调用来附加/上传二进制或base64编码的数据，最后一个调用来完成上传，并使media_id与其他资源。

所以它是这样工作的：

  • 请求1：发送一个以字节为单位的video大小的init请求。 这将返回一个媒体ID号码，我们必须在请求2和3中使用。

  • 请求2：使用请求1中返回的媒体ID号码上传video数据。

  • 请求3：一旦video上传完成，发送一个“FINALIZE”请求回到Twitter的API。 这让Twitter API知道video文件的所有块已经完成上传。

注意 Twitter API以“块”接受video上传。 因此，如果您的video文件相当大，您可能需要将其分成多个文件，因此您将不得不多次重复“请求2”（不要忘记每次增加“segment_index”编号）。

我已经去了下面的代码。 尝试一下，并尝试一下。 稍后我会更新我的答案以改进它。 

 -(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { // Assign the mediatype to a string NSString *mediaType = [info objectForKey:UIImagePickerControllerMediaType]; // Check the media type string so we can determine if its a video if ([mediaType isEqualToString:@"public.movie"]) { NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL]; NSData *webData = [NSData dataWithContentsOfURL:videoURL]; // Get the size of the file in bytes. NSString *yourPath = [NSString stringWithFormat:@"%", videoURL]; NSFileManager *man = [NSFileManager defaultManager]; NSDictionary *attrs = [man attributesOfItemAtPath:yourPath error: NULL]; UInt32 result = [attrs fileSize]; //[self tweetVideoStage1:webData :result]; [self tweetVideo:webData :result :1 :@"n/a"]; } } -(void)tweetVideo:(NSData *)videoData :(int)videoSize :(int)mode :(NSString *)mediaID { NSURL *twitterVideo = [NSURL URLWithString:@"https://upload.twitter.com/1.1/media/upload.json"]; // Set the parameters for the first twitter video request. NSDictionary *postDict; if (mode == 1) { postDict = @{@"command": @"INIT", @"total_bytes" : videoSize, @"media_type" : @"video/mp4"}; } else if (mode == 2) { postDict = @{@"command": @"APPEND", @"media_id" : mediaID, @"segment_index" : @"0", @"media" : videoData }; } else if (mode == 3) { postDict = @{@"command": @"FINALIZE", @"media_id" : mediaID }; } SLRequest *postRequest = [SLRequest requestForServiceType:SLServiceTypeTwitter requestMethod:SLRequestMethodPOST URL:requestURL:twitterVideo parameters:postDict]; // Set the account and begin the request. postRequest.account = account; [postRequest performRequestWithHandler:^(NSData *responseData, NSHTTPURLResponse *urlResponse, NSError *error) { if (!error) { if (mode == 1) { // Parse the returned data for the JSON string // which contains the media upload ID. NSMutableDictionary *returnedData = [NSJSONSerialization JSONObjectWithData:responseData options:NSJSONReadingMutableContainers error:&error] NSString *tweetID = [NSString stringWithFormat:@"%@", [returnedData valueForKey:@"media_id_string"]]; [self tweetVideo:videoData :result :2 :tweetID]; } else if (mode == 2) { [self tweetVideo:videoData :result :3 :mediaID]; } } else { NSLog(@"Error stage %d - %", mode, error); } }]; }

更新 – Twitter的API错误 – https://dev.twitter.com/overview/api/response-codes

在回答你的第一条评论时，错误503意味着Twitter服务器已经过载，并且无法立即处理你的请求。

503服务不可用Twitter服务器已启动，但超载请求。 稍后再试。

我知道如何上传video到twitter使用新的API。 我已经尝试过了，它可以工作。

请检查这个： https ： //github.com/liu044100/SocialVideoHelper

你只需要调用这个类的方法。 

 +(void)uploadTwitterVideo:(NSData*)videoData account:(ACAccount*)account withCompletion:(dispatch_block_t)completion;

希望它能解决你的问题。

最好的祝福。

一直在Twitter上寻找分享video解决scheme的function如下：

  • 支持块上传
  • 内置支持用户的凭证检索

由于我找不到满足需求的人，所以我决定写一个。

https://github.com/mtrung/TwitterVideoUpload

我已经testing了一段时间，对我来说效果很好。

希望能帮助到你，

问候。

在@Dan的答案尝试这个基础。 它没有testing，但我认为它可以工作。

使用cocoa豆荚 ： pod'TwitterKit'

如果你不使用面料尝试与面料 

 //for Extern call //Mode is 1 //MediaId is 0 - (void)uploadTwitterVideo:(NSData*)videoData videoTitle:(NSString *)title desc:(NSString *)desc withMode:(int)mode mediaID:(NSString *)mediaID withCompletion:(dispatch_block_t)completion { NSString *twitterPostURL = @"https://upload.twitter.com/1.1/media/upload.json"; NSDictionary *postParams; if (mode == 1) { postParams = @{@"command": @"INIT", @"total_bytes" : [NSNumber numberWithInteger: videoData.length].stringValue, @"media_type" : @"video/mp4"}; } else if (mode == 2) { postParams = @{@"command": @"APPEND", @"media_id" : mediaID, @"segment_index" : @"0"}; } else if (mode == 3) { postParams = @{@"command": @"FINALIZE", @"media_id" : mediaID }; } else if (mode == 4) { postParams = @{@"status": desc, @"media_ids" : @[mediaID]}; } TWTRAPIClient *twitterInstance = [[Twitter sharedInstance] APIClient]; NSError *error; NSURLRequest *requestTw = [twitterInstance URLRequestWithMethod:@"POST" URL:twitterPostURL parameters:postParams error:&error]; [twitterInstance sendTwitterRequest:requestTw completion:^(NSURLResponse * _Nullable response, NSData * _Nullable data, NSError * _Nullable connectionError) { NSLog(@"HTTP Response: %li, responseData: %@", (long)response, [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]); if (error) { NSLog(@"There was an error:%@", [error localizedDescription]); } else { if (mode == 1) { NSMutableDictionary *returnedData = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingMutableContainers error:&connectionError]; NSString *mediaIDResponse = [NSString stringWithFormat:@"%@", [returnedData valueForKey:@"media_id_string"]]; NSLog(@"stage one success, mediaID -> %@", mediaID); [self uploadTwitterVideo:videoData videoTitle:title desc:desc withMode:2 mediaID:mediaIDResponse withCompletion:completion]; } else if (mode == 2) { [self uploadTwitterVideo:videoData videoTitle:title desc:desc withMode:3 mediaID:mediaID withCompletion:completion]; } else if (mode == 3) { [self uploadTwitterVideo:videoData videoTitle:title desc:desc withMode:4 mediaID:mediaID withCompletion:completion]; } else if (mode == 4) { DispatchMainThread(^(){completion();}); } } }]; }

这个API工作如下。

– 在安装应用程序（twitter）时以及未安装时login

– 优先从设置取得凭证

检查这种情况

迅速

它非常简单。 首先，您需要login到您的Twitter帐户。 转到手机设置，然后单击Twitter应用程序并login。现在只需在任何地方调用此videoUploadfunction

video或Chunked上传方法 参考

replace您的videotypes/扩展在该代码并仔细阅读所有twitter的要求 。

我能够成功上传video到twitter！ 以下是twitter文档中提到的步骤：

  1. 请求Twitter帐户 

     accountStore.requestAccessToAccounts(with: twitterAccountType,options:nil){(granted, error) in

  2. POST媒体/上传（INIT） 

     params["command"] = "INIT" params["total_bytes"] = String(videoData.length) params["media_type"] = "video/mov"

  3. POST媒体/上传（APPEND） 

     params["command"] = "APPEND" params["media_id"] = mediaId params["segment_index"] = String(chunk)

  4. POST媒体/上传（FINALIZE） 

     params["command"] = "FINALIZE" params["media_id"] = mediaId

  5. POST媒体/上传 

     params["status"] = twitterDescription params["media_ids"] = mediaId
