Question

我尝试上传超过10 MB的视频，当我通过ASIHTTPRequest发送它然后它开始连接但没有将该电影上传到网络

Answer 1

可能是由于服务器端的大小限制

-edit-

使用NSURLConnection上传以下请求（如果您使用多部分表单数据，通常就是这种情况）：

// some random value

 NSString *boundary = @"0xKhTmLbOuNdArY---ThIs_Is_mY_BoUnDaRyY---pqo";


 NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url 
                 cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:20.0];
 [request setHTTPMethod:@"POST"];


 NSString *theContentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
 [request setValue:theContentType forHTTPHeaderField:@"Content-type"];

 NSData *theData = data;// here use your movie data

 //adding the body:
 NSMutableData *postBody = [NSMutableData data];

// data part 

[postBody appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"content\"; filename=\"dummy%i.mp4\"\r\n",[[NSDate date]timeIntervalSince1970]] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[[NSString stringWithFormat:@"Content-Type: %@\r\n",contentType] dataUsingEncoding:NSUTF8StringEncoding]];
[postBody appendData:[@"Content-Transfer-Encoding: binary\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[postBody appendData:theData];
[postBody appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];


// final boundary

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

 [request setHTTPBody:postBody];
 [request setValue:param forHTTPHeaderField:@"Parameter"];

我使用这种方式解决了这个问题，基本上由于服务器上传限制而产生错误
