上傳視頻文件到URL

Question

我想上傳視頻文件到指定的網址。當我按下按鈕視頻文件應該上傳到我使用的網址。但沒有反應。任何人都可以給出理由。

enter code here 


    NSString *filePath = [[NSBundle mainBundle]pathForResource:@"3idiots" ofType:@"mov"]; 
    NSURL *uploadurl=[NSURL URLWithString:@"http://115.111.27.206:8081/vblo/upload.jsp"]; 

//NSData *postVideoData = [NSData dataWithContentsOfFile:filePath]; 
NSData *postVideoData = [string dataUsingEncoding:NSASCIIStringEncoding   allowLossyConversion:YES]; 
NSString *postVideoLength = [NSString stringWithFormat:@"%d", [postVideoData length]]; 

NSMutableURLRequest *request12 = [[[NSMutableURLRequest alloc] init] autorelease]; 
[request12 setURL:uploadurl]; 
[request12 setHTTPMethod:@"POST"]; 
[request12 setValue:postVideoLength forHTTPHeaderField:@"Content-Length"]; 
[request12 setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; 
[request12 setHTTPBody:postVideoData]; 

NSURLConnection的* theConnection12 = [[NSURLConnection的頁頭] initWithRequest：request12委託：自我];

if（theConnection12） webData12 = [[NSMutableData data] retain];

} 別的 {

}

}

- （無效）連接：（NSURLConnection的*）連接didReceiveResponse：（NSURLResponse *）響應 {

[webData12 setLength:0]; 

- （void）連接：（NSURLConnection *）連接didReceiveData：（N SDATA *）數據 {

[webData12 appendData:data]; 

} - （無效）connectionDidFinishLoading：（NSURLConnection的*）連接 { 的NSString * loginStatus12 = [[的NSString的alloc] initWithBytes：[webData12 mutableBytes]長度：[webData12長度]編碼：NSUTF8StringEncoding]; NSLog（loginStatus12）;

if(loginStatus12) 
{ 
    UIAlertView *statusAlert12 = [[UIAlertView alloc]initWithTitle:nil message:(NSString *)loginStatus12 delegate:self cancelButtonTitle:@"cancel" otherButtonTitles:nil]; 
    [statusAlert12 show]; 
} 
}

你需要發送請求，您將HTTPBody

NSData *serverReply = [NSURLConnection sendSynchronousRequest: request12 returningResponse:&response error:&error];
