我正在通过 HTTP 发布将视频上传到服务器。
如何通过单击某些按钮来暂停和恢复此上传过程
我正在使用以下代码
NSString *urlString =@"http://sampleurl.com/upload_video";
NSMutableURLRequest *request= [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"user_id\"\r\n\r\n%@", appDelegate.userid] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"video\"; filename=\"%@\"\r\n", @"a.mov"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[postbody appendData:[NSData dataWithData:file]];
[postbody appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postbody];
conn = [[NSURLConnection alloc] initWithRequest:request delegate:self];
if (conn) {
webData = [[NSMutableData data] retain];
}
