Multiform数据发送到服务器使用iPhone sdk

Question

我一直在试图遵循一些上传数据到网站的例子。我想将邮件另存为.txt文件。任何想法在这里做什么？

- (IBAction)sendSerializedGreeting:(id)sender; 
{ 
    NSString *message; 
    message =@"Here we go for a test message."; 
    // Show a loading indicator 
    [UIApplication sharedApplication].networkActivityIndicatorVisible = YES; 

    NSString *greetingURL = [NSString stringWithFormat:@"http://www.site.com/upload.php"]; 

    NSMutableURLRequest *theRequest = [NSMutableURLRequest requestWithURL:[NSURL URLWithString:greetingURL] 
      cachePolicy:NSURLRequestUseProtocolCachePolicy timeoutInterval:60.0]; 

    NSDictionary *headerFieldsDict = [NSDictionary dictionaryWithObjectsAndKeys:@"text/xml; charset=utf-8", @"Content-Type", nil]; 

    [theRequest setHTTPBody:[message dataUsingEncoding:NSUTF8StringEncoding]]; 
    [theRequest setAllHTTPHeaderFields:headerFieldsDict]; 
    [theRequest setHTTPMethod:@"POST"]; 

    // create the connection with the request and start loading the data 
    NSURLConnection *theConnection = [[NSURLConnection alloc] initWithRequest:theRequest delegate:self]; 

    if (theConnection == nil) 
    { 
     NSLog(@"Failed to create the connection"); 
    } 
} 

这是upload.php文件。我假设这个问题是与此但不知道。我不知道上面例子中的文件名被设置在哪里。这段代码是从别的地方使用的。

<?php 
$uploaddir = './';  //Uploading to same directory as PHP file 

$file = basename($_FILES['userfile']['name']); 

$uploadFile = $file; 
$randomNumber = rand(0, 99999); 
$newName = $uploadDir . $randomNumber . $uploadFile; 

if (is_uploaded_file($_FILES['userfile']['tmp_name'])) { 
    echo "Temp file uploaded."; 
} else { 
    echo "Temp file not uploaded."; 
} 

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $newName)) { 

} 
?>

我通过这个代码发送到服务器的图像....使用文本文件或任何类型的数据多种形式

 NSString *strUrl=@"http://www.site.com/upload.php"; 
     NSLog(@"%@",strUrl); 
     NSURL *url=[NSURL URLWithString:strUrl]; 

     NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url 
                   cachePolicy:NSURLRequestUseProtocolCachePolicy 
                  timeoutInterval:130.0]; 

     // file name of user picture 
// I am sending a image to server 
     NSString *fileName=[[eMailTxtField.text stringByReplacingOccurrencesOfString:@"@" withString:@"-"] stringByAppendingString:@".jpg"]; 
     //image data 
     UIImage *userImage=imgUser.image; 
     NSData *imageData =UIImageJPEGRepresentation(userImage, 90); 

     NSMutableData *myRequestData = [[NSMutableData alloc] init]; 
     [myRequestData appendData:[NSData dataWithBytes:[postData UTF8String] length:[postData length]]]; 


     NSString *boundary = [NSString stringWithString:@"--"]; 
     NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary]; 
     [request addValue:contentType forHTTPHeaderField: @"Content-Type"]; 
     [myRequestData appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
     [myRequestData appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"uploadfile\"; filename=\"%@\"\r\n", fileName] dataUsingEncoding:NSUTF8StringEncoding]]; 
     [myRequestData appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; 
     [myRequestData appendData:[NSData dataWithData:imageData]]; 
     [myRequestData appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 

     [ request setHTTPMethod: @"POST" ]; 

     [ request setHTTPBody: myRequestData ]; 
     NSURLResponse *response; 
     NSError *error; 
     NSData *returnData = [NSURLConnection sendSynchronousRequest: request returningResponse:&response error:&error]; 
     if (!error && returnData) { 
      NSString *content = [NSString stringWithUTF8String:[returnData bytes]]; 
      [self registerWithJsonString:content]; 
     } 
     else{ 
      [self showServerNotFoundError]; 
     }
