同じhttppostリクエストを介してテキスト情報(テキスト文字列)と画像ファイルをサーバーにアップロードするにはどうすればよいですか。画像を単独でアップロードしましたが、テキストを使用できません。ありがとう!

このコードを使用して、画像とtextLabelをアップロードします
NSData *imageData = UIImageJPEGRepresentation("yourImage",0.2); //change Image to NSData
if (imageData != nil)
{
filenames = [NSString stringWithFormat:@"TextLabel"]; //set name here
NSLog(@"%@", filenames);
NSString *urlString = @"http://xxxxxxx/yyyyy.php";
NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"filenames\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[filenames dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userfile\"; filename=\".jpg\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Type: application/octet-stream\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(returnString);
NSLog(@"finish");
}
PHP側では、このコードを使用します
$myparam = $_POST['userfile']; //getting image Here
$mytextLabel= $_POST['filenames'] //getting textLabe Here
echo $myparam;
echo $mytextLabel;
$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['myfile']['name']);
if(move_uploaded_file($_FILES['myfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['myfile']['name']) . " has been uploaded";
} else {
echo "There was an error uploading the file, please try again!";
}

クリック時にボタンに次のメソッドを追加するだけです:
-(void) uploadImage
{
prodNam = txtProdName.text;
UIImage * img = [UIImage imageNamed:@"SRT2.jpg"];
NSData *imageData = UIImageJPEGRepresentation(img,0.2); //change Image to NSData
if (imageData != nil)
{
NSString * filenames = [NSString stringWithFormat:@"TextLabel"];
NSLog(@"%@", filenames);
NSString *urlString = @"http://dev9.edisbest.com/upload_image.php";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init] ;
[request setURL:[NSURL URLWithString:urlString]];
[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];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"filenames\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[filenames dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\"TestEdreamzIpad.jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:body];
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"Response : %@",returnString);
if([returnString isEqualToString:@"Success ! The file has been uploaded"])
{
UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"Success" message:@"Image Saved Successfully" delegate:self cancelButtonTitle:@"Ok" otherButtonTitles:nil];
[alert show];
}
NSLog(@"Finish");
}
}
xcodeローカル階層の「SRT2.jpg」の場所に任意の画像を配置できます。
ではごきげんよう...

サーバーにファイルをアップロードするには、単にユーザーSVHttpリクエストを使用します。
imageFileやその他のものをパラメータで送信します:
NSMutableDictionary *data = [[NSMutableDictionary alloc] init];
[data setObject:imageData forKey:@"image"];
[data setObject:@"saveimage" forKey:@"action"];
[data setObject:userId forKey:@"userid"];
[data setObject:@"png" forKey:@"type"];
そしてリクエストをしてください:
SVHTTPClient *request = [SVHTTPClient sharedClient];
[request setBasicAuthWithUsername:nil password:nil];
[request setSendParametersAsJSON:NO];
[request POST:[NSString stringWithFormat:@"http://bylyngo.com/getapi/?action=saveimage&userid=%@&type=png",userId]
parameters:data
progress:^(float progress) {
NSLog(@"Uploading (%.0f%%)", progress*100);
}];
あなたも進歩を得るでしょう。

私のWebサービスはこれで、正常に機能しています。
<?php
$fp = fopen("./trace.txt", "w"); //creates a file to trace your data
fwrite($fp,"get \n");
fwrite($fp, print_r($_GET, true));
fwrite($fp,"POST \n");
fwrite($fp, print_r($_POST, true));//displays the POST
fwrite($fp,"FILES \n");
fwrite($fp,print_r($_FILES,true));//display the FILES
fclose($fp);
$myparam = $_POST["userfile"];
$mytextLabel = $_POST['filenames'];
echo $myparam;
echo $mytextLabel;
$uploadDir = 'uploads/'; //you must create this directory
$uploadDir = $uploadDir.basename($_FILES['myfile']['name']); //saves the picture inside that folder
$file = basename($_FILES['uploaded']['name']);
//$uploadedFile = $uploadDir.$file;
//move_uploaded_file($_FILES['uploaded']['tpm_name']);
if(move_uploaded_file($_FILES['myfile']['tpm_name'],$uploadDir)){
echo "the file ".basename($_FILES['myfile']['name'])." has been uploaded" ;
}else{
echo "error";
}
?>
