Question

尝试将视频文件发布到服务器，以字节为单位发布。我在下面发布我的代码用于发布。

-(void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info
{
NSString* mediaType = [info objectForKey:UIImagePickerControllerMediaType];
if ( [mediaType isEqualToString:@"public.movie" ])
{        
    if (CFStringCompare ((__bridge CFStringRef) mediaType, kUTTypeMovie, 0)
        == kCFCompareEqualTo)
    {

        NSURL *videoUrl=(NSURL*)[info objectForKey:UIImagePickerControllerMediaURL];
        NSData *webData = [NSData dataWithContentsOfURL:videoUrl];
        [self post:webData];

        if([profile isEqualToString:@"friend"])
        {
            [self callServerFriend];
        }
        if([profile isEqualToString:@"public"])
        {
            [self callServerPublic];
        }
    }
 }    

- (void)post:(NSData *)fileData
{
NSLog(@"POSTING");

index1 = [[NSUserDefaults standardUserDefaults] integerForKey:@"videoName"];
valIndex1 = index1;
NSString *str = [NSString stringWithFormat:@"video_%d.mp4",valIndex];

// Generate the postdata:
NSData *postData = [self generatePostDataForData: fileData];

profileImg = profilePic;

NSArray *arrImg = [profileImg componentsSeparatedByString:@"/"];
NSString *strImg1 = [arrImg objectAtIndex:[arrImg count]-2];
NSString *strImg2 = @"/";
NSString *strImg3 = [arrImg lastObject];
//NSLog(@"img2-----------------%@",strImg2);
NSString *pImg = [NSString stringWithFormat:@"%@%@%@",strImg1, strImg2, strImg3];
NSLog(@"img-----------------%@",pImg);

// Setup the request:

NSString *urlString = [[NSString stringWithFormat:@"http://www.myvnt.co/overheadPost.php?userId=%@&type=Video&text=%@&image=%@&location=%@&Upload=Upload", uid, statusPost, pImg, locc]stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding];

NSMutableURLRequest *wigiRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:urlString]
                                                           cachePolicy:NSURLRequestUseProtocolCachePolicy
                                                       timeoutInterval:30.0];
[wigiRequest setHTTPMethod:@"POST"];

// just some random text that will never occur in the body
NSString *stringBoundary = @"0xKhTmLbOuNdArY---This_Is_ThE_BoUnDaRyy---pqo";

// header value
NSString *headerBoundary = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",
                            stringBoundary];

// set header
[wigiRequest addValue:headerBoundary forHTTPHeaderField:@"Content-Type"];

//add body
NSMutableData *postBody = [NSMutableData data];
NSLog(@"body made");

//IMAGE Posting

[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];
//"Content-Disposition: form-data; name=\"fileUpload\";filename=\"" + imagePath + "\"" + lineEn

//[postBody appendData:[@"Content-Disposition: form-data; name=\"fileUpload\"; filename=\"img.mp4\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

[postBody appendData:[[NSString stringWithString:[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"fileUpload\"; filename=\"%@\"\r\n", str]] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"Content-Type: image/png\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"Content-Transfer-Encoding: binary\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

NSString *post = [NSString stringWithCString:"--AaB03x\r\nContent-Disposition: form-data; name=\"uploadFile\"; filename=\"img.mp4\"\r\nContent-Type: application/octet-stream\r\nContent-Transfer-Encoding: binary\r\n\r\n" encoding:NSASCIIStringEncoding];

// Get the post header int ASCII format:
NSData *postHeaderData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

// Generate the mutable data variable:
postData = [[NSMutableData alloc] initWithLength:[postHeaderData length] ];
//[postData setData:postHeaderData];

// add it to body
[postBody appendData:postData];
[postBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

// final boundary
[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", stringBoundary] dataUsingEncoding:NSUTF8StringEncoding]];

// add body to post
[wigiRequest setHTTPBody:postBody];

NSLog(@"body set");
// pointers to some necessary objects
NSHTTPURLResponse* response =[[NSHTTPURLResponse alloc] init];
NSError* error = [[NSError alloc] init] ;


// synchronous filling of data from HTTP POST response
NSData *respData = [NSURLConnection sendSynchronousRequest:wigiRequest returningResponse:&response error:&error];

NSLog(@"just sent request");

NSString *responseHTML = [[NSString alloc] initWithBytes:[respData bytes]
                                                  length:[respData length]
                                                encoding:NSUTF8StringEncoding];
NSLog(@"response dictionary : %@",responseHTML);

index1++;
[[NSUserDefaults standardUserDefaults] setInteger:index forKey:@"videoName"];
[[NSUserDefaults standardUserDefaults] synchronize];

}

- (NSData *)generatePostDataForData:(NSData *)uploadData
{
// Generate the post header:
NSString *post = [NSString stringWithCString:"--AaB03x\r\nContent-Disposition: form-data; name=\"uploadFile\"; filename=\"img.mp4\"\r\nContent-Type: application/octet-stream\r\nContent-Transfer-Encoding: binary\r\n\r\n" encoding:NSASCIIStringEncoding];

// Get the post header int ASCII format:
NSData *postHeaderData = [post dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];

// Generate the mutable data variable:
NSMutableData *postData = [[NSMutableData alloc] initWithLength:[postHeaderData length] ];
[postData setData:postHeaderData];

// Add the image:
[postData appendData: uploadData];

// Add the closing boundry:
[postData appendData: [@"\r\n--AaB03x--" dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES]];

// Return the post data:
return postData;
}

另一件事是它每次发布同名视频，所以每个新帖子都会替换前一个。但主要问题是为什么它以字节为单位发布我没有得到。请指导以上。提前谢谢。

试试这个，我用当前的Date-Time ::

存储了它

-(void)imagePickerController:(UIImagePickerController*)picker didFinishPickingMediaWithInfo:(NSDictionary*)info
{
    [self dismissViewControllerAnimated:NO completion:nil];
    NSString *type = [info objectForKey:UIImagePickerControllerMediaType];

    if ([type isEqualToString:(NSString *)kUTTypeVideo] || [type isEqualToString:(NSString *)kUTTypeMovie])
    {
        videoURL = [info objectForKey:UIImagePickerControllerMediaURL];

        NSLog(@"found a video");

        // Code To give Name to video and store to DocumentDirectory //

        videoData = [[NSData dataWithContentsOfURL:videoURL] retain];
        NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
        NSString *documentsDirectory = [paths objectAtIndex:0];

        NSDateFormatter *dateFormat = [[[NSDateFormatter alloc] init] autorelease];
        [dateFormat setDateFormat:@"dd-MM-yyyy||HH:mm:SS"];
        NSDate *now = [[[NSDate alloc] init] autorelease];
        theDate = [dateFormat stringFromDate:now];

        NSString *dataPath = [documentsDirectory stringByAppendingPathComponent:@"Default Album"];

        if (![[NSFileManager defaultManager] fileExistsAtPath:dataPath])
           [[NSFileManager defaultManager] createDirectoryAtPath:dataPath withIntermediateDirectories:NO attributes:nil error:nil];

        NSString *videopath= [[[NSString alloc] initWithString:[NSString stringWithFormat:@"%@/%@.mov",documentsDirectory,theDate]] autorelease];

        BOOL success = [videoData writeToFile:videopath atomically:NO];

        NSLog(@"Successs:::: %@", success ? @"YES" : @"NO");
        NSLog(@"video path --> %@",videopath);
    }
}

视频上传::

videoData 来自videoData = [[NSData dataWithContentsOfURL:videoURL] retain];

- (void)uploadVideo
{
    NSData *imageData = videoData;

    NSString *urlString=[NSString stringWithFormat:@"%s", UploadVideoService];
    NSLog(@"url=== %@", urlString);

    request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];

    NSString *boundary = @"---------------------------14737809831466499882746641449";
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
    [request addValue:contentType forHTTPHeaderField: @"Content-Type"];

    /*  body of the post */

    NSMutableData *body = [NSMutableData data];
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    //Video Name with Date-Time
    NSDateFormatter *dateFormat=[[NSDateFormatter alloc]init];
    [dateFormat setDateFormat:@"yyyy-MM-dd-hh:mm:ssa"];
    NSString *currDate = [dateFormat stringFromDate:[NSDate date]];

    NSString *str = [NSString stringWithFormat:@"Content-Disposition: form-data; name=\"file\"; filename=\"video-%@.mov\"\r\n", currDate];
    NSLog(@"String name::  %@",str);

    [dateFormat release];

    [body appendData:[[NSString stringWithString:str] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[NSData dataWithData:imageData]];
    [body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    [request setHTTPBody:body];

    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];

    NSLog(@"result from webservice:::--> %@", returnString);

    [returnString release];
}

希望，它会帮助你。

感谢。
