Загрузить форму с изображением и nsstrings в файл PHP

Question

Я пытаюсь отправить данные формы, у которых есть изображение, и 2 nsstrings в php-файл, и я хочу отправить uiimage .image с именем «document» и nsstring с имя «имя» и другое nsstring с именем «userid».

Вот мой код.

NSData *imageData = UIImageJPEGRepresentation(Myimage.image, 1.0); 
       if (imageData != nil) 
       { 
        NSString *filename = [NSString stringWithFormat:@"%@",name];  //set name here 
        NSLog(@"%@", filename); 
        NSString *urlString = @"http://URL/upload.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:[filename dataUsingEncoding:NSUTF8StringEncoding]]; 
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]]; 
        [body appendData:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\".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(@"%@", returnString); 
        NSLog(@"finish"); 
}

Попробуйте использовать Afnetworking 3,0

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@"your server url" parameters:@{@"parameter_1":@"string 1",@"parameter_2":@"string 2"} constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
      if (image) { 
       [formData appendPartWithFileData:UIImageJPEGRepresentation(image, 0.8) name:imagename fileName:@"recipeImage.jpg" mimeType:@"image/jpeg"]; 
      } 

     }error:nil]; 

     AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]]; 
     manager.responseSerializer = [AFJSONResponseSerializer serializer]; 

     NSURLSessionUploadTask *uploadTask; 
     uploadTask = [manager 
         uploadTaskWithStreamedRequest:request 
         progress:^(NSProgress * _Nonnull uploadProgress) { 
          dispatch_async(dispatch_get_main_queue(), ^{ 
          }); 
         } 
         completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { 
          if (error) { 
           NSLog(@"Error: %@", [[NSString alloc]initWithData:[[error valueForKey:@"userInfo"] valueForKey:@"com.alamofire.serialization.response.error.data"] encoding:NSUTF8StringEncoding]); 

          } else { 
           NSLog(@"%@",responseObject);// your response here 
           callback(YES,responseObject); 
          } 
         }]; 

     [uploadTask resume];

NSData *dataImage = UIImagePNGRepresentation(yourImage); 

NSString *imageBase64 = [dataImage base64forData]; 

- (NSString*)base64forData 
{ 
    const uint8_t* input = (const uint8_t*)[self bytes]; 
    NSInteger Datalength = [self length]; 

    static char table[] = "ABCDEFGHIJKLMNOPQRSTUVWXYZabcdefghijklmnopqrstuvwxyz/="; 

    NSMutableData* data = [NSMutableData dataWithLength:((Datalength + 2)/3) * 4]; 
    uint8_t* output = (uint8_t*)data.mutableBytes; 

    NSInteger i; 
    for (i=0; i < Datalength; i += 3) { 
     NSInteger value = 0; 
     NSInteger j; 
     for (j = i; j < (i + 3); j++) { 
      value <<= 8; 

      if (j < Datalength) { 
       value |= (0xFF & input[j]); 
      } 
     } 

     NSInteger theIndex = (i/3) * 4; 
     output[theIndex + 0] =     table[(value >> 18) & 0x3F]; 
     output[theIndex + 1] =     table[(value >> 12) & 0x3F]; 
     output[theIndex + 2] = (i + 1) < Datalength ? table[(value >> 6) & 0x3F] : '='; 
     output[theIndex + 3] = (i + 2) < Datalength ? table[(value >> 0) & 0x3F] : '='; 
    } 

    return [[NSString alloc] initWithData:data encoding:NSASCIIStringEncoding];
