iOSからPHPサーバーに画像をアップロードする

この質問も以前に尋ねられたことは知っていますが、私の問題は少し異なります。

PHPサーバーに画像をアップロードし、iOSから画像とともにさらにパラメーターを送信したい。グーグルで検索して、2つの解決策を見つけた。

  1. JSONのBase64エンコードされた文字列として画像を送信するか、どちらかです。参照 リンク 。

  2. または、フォームデータを使用してサーバーに画像をアップロードします。私はこれを参照しました link 。誰かが私をこのように呼んでくれたら、このAPIにパラメーターを追加するのを手伝ってください。

私の質問は、サーバーに画像をアップロードする最良の方法であり、同じWebサービス呼び出しでより多くのパラメーター（ユーザー名、パスワード、および詳細）を送信する必要があることです。

前もって感謝します。

次の2つの方法で、iOSアプリからPHP serverに画像をアップロードできます。

を使用新しいAFNetworking ：

#import "AFHTTPRequestOperation.h"
#import "AFHTTPRequestOperationManager.h"

    NSString *stringUrl =@"http://www.myserverurl.com/file/uloaddetails.php?"
    NSString *string =@"http://myimageurkstrn.com/img/myimage.png"       
    NSURL *filePath = [NSURL fileURLWithPath:string];

   NSDictionary *parameters  = [NSDictionary dictionaryWithObjectsAndKeys:userid,@"id",String_FullName,@"fname",String_Email,@"emailid",String_City,@"city",String_Country,@"country",String_City,@"state",String_TextView,@"bio", nil];

    AFHTTPRequestOperationManager *manager = [AFHTTPRequestOperationManager manager];

    [manager POST:stringUrl parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData)
     {
         [formData appendPartWithFileURL:filePath name:@"userfile" error:nil];//here userfile is a paramiter for your image 
     }
     success:^(AFHTTPRequestOperation *operation, id responseObject)
     {
         NSLog(@"%@",[responseObject valueForKey:@"Root"]);
         Alert_Success_fail = [[UIAlertView alloc] initWithTitle:@"myappname" message:string delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
         [Alert_Success_fail show];     

     }
     failure:^(AFHTTPRequestOperation *operation, NSError *error)
     {
         Alert_Success_fail = [[UIAlertView alloc] initWithTitle:@"myappname" message:[error localizedDescription] delegate:self cancelButtonTitle:@"ok" otherButtonTitles:nil, nil];
         [Alert_Success_fail show];

     }];

2番目に使用するNSURLConnection：

-(void)uploadImage
    {       
        NSData *imageData = UIImagePNGRepresentation(yourImage);

        NSString *urlString = [ NSString stringWithFormat:@"http://yourUploadImageURl.php?intid=%@",1];

        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 stringWithString:[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@\"\r\n", 1]] 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]];
        [request setHTTPBody:body];

        [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    }

アプリからphpサーバーに画像をアップロードするためのこの両方の方法は、これがあなたに役立つことを願っています。

これを試してみてください、これは私の仕事です。

    NSData *postData = [Imagedata dataUsingEncoding:NSASCIIStringEncoding allowLossyConversion:YES];
    NSString *postLength = [NSString stringWithFormat:@"%d", [postData length]];
    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [request setURL:[NSURL URLWithString:apiString]];
    [request setHTTPMethod:@"POST"];
    [request setValue:postLength forHTTPHeaderField:@"Content-Length"];
    [request setValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"];
    [request setHTTPBody:postData];

    NSURLResponse *response;
    NSError *err;
    NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&err];
    NSString *responseString = [[NSString alloc] initWithData:responseData encoding: NSUTF8StringEncoding];


    NSError *jsonError;
    NSData *objectData = [responseString dataUsingEncoding:NSUTF8StringEncoding];
    NSDictionary *responseDictft = [NSJSONSerialization JSONObjectWithData:objectData
                                                                   options:NSJSONReadingMutableContainers
                                                                     error:&jsonError];

AFNetworking を使用すると、次のようになります。

NSMutableDictionary *params = [[NSMutableDictionary alloc]init];
    [params setObject:@"myUserName" forKey:@"username"];
    [params setObject:@"1234" forKey:@"password"];
    [[AFHTTPRequestOperationLogger sharedLogger] startLogging];

    AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:url];
       imageData = UIImageJPEGRepresentation(mediaFile, 0.5);


    NSMutableURLRequest *request = [httpClient multipartFormRequestWithMethod:@"POST" path:nil parameters:params constructingBodyWithBlock: ^(id <AFMultipartFormData>formData)
    {
              [formData appendPartWithFileData:imageData name:@"mediaFile" fileName:@"picture.png" mimeType:@"image/png"];
    }];

    AFJSONRequestOperation *operation = [AFJSONRequestOperation JSONRequestOperationWithRequest:request

    success:^(NSURLRequest *request, NSHTTPURLResponse *response, id JSON)
    {

        UIAlertView *alert = [[UIAlertView alloc] initWithTitle:@"File was uploaded" message:@""
