如何将字符串和视频发布到PHP服务器？

Question

我有以下问题..我想视频数据和一些字符串张贴到PHP服务器。我能够发布视频数据，但我不知道如何添加字符串。下面是我使用的代码，它做工精良张贴视频，但现在我要添加文本的帖子。

- (NSData *)generatePostDataForData:(NSData *)uploadData 
{ 
    // Generate the post header: 
    NSString *post = [NSString stringWithCString:"--AaB03x\r\nContent-Disposition: form-data; name=\"video_mp4\"; filename=\"movie.mp4\"\r\nContent-Type: video/mp4\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 video: 
    [postData appendData: uploadData]; 

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

    // Return the post data: 
    return postData; 
} 

-(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://pik.bg/android_test.php"] cachePolicy: NSURLRequestReloadIgnoringLocalCacheData timeoutInterval: 30]; 
    [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]; 
    NSData *returnData = [NSURLConnection sendSynchronousRequest:uploadRequest returningResponse:nil error:nil]; 
    NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 
    NSLog (@"%@", returnString); 
} 

    // Button for sending the news to the web. 
-(IBAction)sendNews:(id)sender 
{ 
    NSData *videoData = [NSData dataWithContentsOfFile:videoString]; 
    [self post:videoData]; 
} 

现在我想添加一些文字到“标题”和“描述”文本框。如何用这种代码做到这一点？

使用这可能是有益的..

NSString *strURL =@"Your URL"; 
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ; 
[request setURL:[NSURL URLWithString:strURL]]; 
[request setHTTPMethod:@"POST"]; 

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


NSMutableData *body = [NSMutableData data]; 
//Image Uploading 
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"Content-Disposition: form-data; name=\"video_mp4\"; filename=\"movie.mp4\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 

NSData *videoData = @"Your video in data Format"; 
[body appendData:[@"Content-Type: video/mp4\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[NSData dataWithData:videoData]]; 
[body appendData:[[NSString stringWithFormat:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 


//Data Sending 
[body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"Your Key That's need on server\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"Your Data That's you want to send on server" dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[request setHTTPBody:body]; 

NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil]; 
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 
NSLog(@"data Return From Server %@",returnString); 

我已经改变了我的答案。现在根据您的服务器需求来检查和安排。
