从iPhone向服务器上传视频文件
我知道如何将图像上传到运行PHP的服务器上,但我一直在上传视频 我曾经上传过我的视频文件 过帐方式都可以。我在服务器上得到的是一个0字节的文件 我的代码如下:从iPhone向服务器上传视频文件,iphone,objective-c,ios,Iphone,Objective C,Ios,我知道如何将图像上传到运行PHP的服务器上,但我一直在上传视频 我曾经上传过我的视频文件 过帐方式都可以。我在服务器上得到的是一个0字节的文件 我的代码如下: - (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info { NSURL *videoURL = [info objectForKey
- (void)imagePickerController:(UIImagePickerController *)picker
didFinishPickingMediaWithInfo:(NSDictionary *)info {
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSData *videoData = [NSData dataWithContentsOfFile:[videoURL path]];
}
此视频数据在我的POST方法中传递
我应该怎么做呢?要发布视频,您需要在图像选择器委派后使用此功能
- (NSData *)generatePostDataForData:(NSData *)uploadData
{
// Generate the post header:
NSString *post = [NSString stringWithCString:"--AaB03x\r\nContent-Disposition: form-data; name=\"upload[file]\"; filename=\"somefile\"\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;
}
- (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"]){
NSLog(@"got a movie");
NSURL *videoURL = [info objectForKey:UIImagePickerControllerMediaURL];
NSData *webData = [NSData dataWithContentsOfURL:videoURL];
[self post:webData];
[webData release];
}
对于后期视频,请使用此功能
- (void)post:(NSData *)fileData
{
NSLog(@"POSTING");
// Generate the postdata:
NSData *postData = [self generatePostDataForData: fileData];
NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
// Setup the request:
NSMutableURLRequest *uploadRequest = [[[NSMutableURLRequest alloc] initWithURL:[NSURL URLWithString:@"http://www.example.com:3000/"] cachePolicy: NSURLRequestReloadIgnoringLocalCacheData timeoutInterval: 30 ] autorelease];
[uploadRequest setHTTPMethod:@"POST"];
[uploadRequest setValue:postLength forHTTPHeaderField:@"Content-Length"];
[uploadRequest setValue:@"multipart/form-data; boundary=AaB03x" forHTTPHeaderField:@"Content-Type"];
[uploadRequest setHTTPBody:postData];
// Execute the reqest:
NSURLConnection *conn=[[NSURLConnection alloc] initWithRequest:uploadRequest delegate:self];
if (conn)
{
// Connection succeeded (even if a 404 or other non-200 range was returned).
NSLog(@"sucess");
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Got Server Response" message:@"Success" delegate:nil cancelButtonTitle:@"OK" otherButtonTitles:nil];
[alert show];
[alert release];
}
else
{
// Connection failed (cannot reach server).
NSLog(@"fail");
}
}
