图像未通过POST上传到服务器的目标C

Question

我正在使用POST方法和multipartMethod将图像从iphone上传到服务器。我的Objective-C代码是

__weak AuthAPIClient *client = [AuthAPIClient sharedClient]; 
    [client setParameterEncoding:AFJSONParameterEncoding]; 
    [client registerHTTPOperationClass:[AFHTTPRequestOperation class]]; 
    [SVProgressHUD showWithStatus:@"Saving data to server..."]; 
    [SVProgressHUD show]; 
    if ([self isInternetAvailable]) { 
    NSString *userId =[[AppSettings sharedAppSettings] getUserName]; 
    NSString*replacedName=[userId stringByReplacingOccurrencesOfString:@" " withString:@"-"]; 
     NSDictionary *parametersDic = @{@"user_name":userName,@"image_data":[NSString stringWithFormat:@"uploads/%@.jpeg",replacedName]}; 

    NSData *jsonData = [NSJSONSerialization dataWithJSONObject:parametersDic options:0 error:nil]; 
    id json = [NSJSONSerialization JSONObjectWithData:jsonData options:0 error:nil]; 


    /////////////////////////////Test code//////////////////////////////// 
    NSData *imageToUpload = UIImageJPEGRepresentation(imagedata, 1.0);///imagedata is an UIImage passing in parameter of method. 
    NSMutableURLRequest *request = [client multipartFormRequestWithMethod:@"POST" path:@"update_profile.php" parameters:json constructingBodyWithBlock: ^(id <AFMultipartFormData>formData) { 
     [formData appendPartWithFileData: imageToUpload name:@"file" fileName:[NSString stringWithFormat:@"%@.jpeg",userId] mimeType:@"image/jpeg"]; 
    }]; 

    ///////////////////////////////////////////////////////////////////// 
    NSLog(@"response request %@",request); 
    AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:request]; 
    [operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) { 

        NSLog(@"Sent %lld of %lld bytes", totalBytesWritten, totalBytesExpectedToWrite); 

       }]; 
[operation setCompletionBlockWithSuccess:^(AFHTTPRequestOperation *operation, id responseObject) 
    { 
     //    [SVProgressHUD dismiss]; 
     NSString *responseString = [[NSString alloc] initWithData:responseObject encoding:NSUTF8StringEncoding]; 
     NSLog(responseString); 
     if (responseString != nil && ![responseString isEqualToString:@""] && operation.response.statusCode == 200) { 
      NSError *error; 
      // NSDictionary *responseDic = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:&error]; 
      NSMutableArray* jsonArray = [NSJSONSerialization JSONObjectWithData:responseObject options:kNilOptions error:&error]; 
      NSLog(@"hello response %@",responseString); 

     } 
     else { 
      NSLog(@"hello response failr %@",responseString); 

      if ([self.delegate respondsToSelector:@selector(serviceHelperSavePersonalInfoDataWithDetailsFailed:error:)]) { 
       [self.delegate serviceHelperSavePersonalInfoDataWithDetailsFailed:self error:@"No Response Recieved."]; 
      } 
     } 

    } 
            failure:^(AFHTTPRequestOperation *operation, NSError *error) { 
             NSLog(@"Error"); 
             //            [SVProgressHUD dismiss]; 

             NSMutableString *errorMsg = [[NSMutableString alloc] init]; 
             [errorMsg appendString:@"Error Occured"]; 

             if(operation.response == nil) 
             { 
              [errorMsg appendString:@"Service not available. Please try again"]; 

             } 
             else if (operation.response.statusCode == 500) { 
              [errorMsg appendString:@"Service not available. Please try again"]; 
             } 
             else if (operation.response.statusCode == 403) { 
              [errorMsg appendString:@"Request forbidden. Please try again"]; 

             } 
             else { 
              NSData *jsonData = [operation.responseString dataUsingEncoding:NSUTF8StringEncoding]; 
              NSDictionary *json = [NSJSONSerialization JSONObjectWithData:jsonData 
                            options:0 
                            error:nil]; 
              if (json != nil) { 
               [errorMsg appendString:[json objectForKey:@"message"]]; 
              } 

             } 

             [errorMsg appendString:@" service is not available."]; 

             if ([self.delegate respondsToSelector:@selector(serviceHelperSavePersonalInfoDataWithDetailsFailed:error:)]) { 
              [self.delegate serviceHelperSavePersonalInfoDataWithDetailsFailed:self error:errorMsg]; 
             } 

            }]; 
    [operation start]; 
} 
else { 

    if ([self.delegate respondsToSelector:@selector(serviceHelperSavePersonalInfoDataWithDetailsFailed:error:)]) { 
     [self.delegate serviceHelperSavePersonalInfoDataWithDetailsFailed:self error:@"Internet not available."]; 
    } 
} 

我的PHP文件（update_profile.php）代码

<?php 
require_once "DatabaseConnection.php"; 
$myfile = fopen("newfile.txt", "w") or die("Unable to open file!"); 
$txt = "not set"; 
if(isset($_FILES)){ 

    $txt = serialize($_FILES); 
    $result = "hellll"; 
} 

fwrite($myfile, $txt); 
fclose($myfile); 
$uploaddir = 'uploads/'; 
    $file = basename($_FILES['file']['name']); 
    $uploadfile = $uploaddir . $file; 

    if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) { 
    // sendResponse(200, 'Upload Successful'); 
    //return true; 
    } 

我用我的其他项目相同的代码，工作不错，但在这个项目不能正常工作。这与EL Capitan OSX有关吗？因为我已更新我的操作系统。任何人有任何想法我错了？任何帮助，将不胜感激。谢谢。

错误是： 数据，并在服务器side.Nothing没有收到图像进来isset（$ _ FILES）和我也有检查$ _ POST和$ _REQUEST但服务器不仅recieving什么“一：0 {}”在节约'newfile.txt'。我正在服务器上创建文件'newfile.txt'，但没有任何文件。

我已用于图像上载下面的代码我认为这可以帮助 -

NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:@“youUrl” parameters:parameters constructingBodyWithBlock:^(id<AFMultipartFormData> formData) { 
    [formData appendPartWithFileData:imageData name:@"file" fileName:@"image.png" mimeType:@"image/png"]; 
} error:nil]; 


NSURLSessionUploadTask *uploadTask; 
uploadTask = [manager 
       uploadTaskWithStreamedRequest:request 
       progress:^(NSProgress * _Nonnull uploadProgress) { 
        // This is not called back on the main queue. 
        // You are responsible for dispatching to the main queue for UI updates 
        dispatch_async(dispatch_get_main_queue(), ^{ 
         //Update the progress view 
         // [self.progressView setProgress:uploadProgress.fractionCompleted]; 

         NSLog(@"Proggress%f",uploadProgress.fractionCompleted); 
        }); 




       } 
       completionHandler:^(NSURLResponse * _Nonnull response, id _Nullable responseObject, NSError * _Nullable error) { 
        if (error) { 
         NSLog(@"Error: %@", error); 
         [HUD setHidden:YES]; 
         UIAlertController *alert=[UIAlertController alertControllerWithTitle:@"Please check Internet Connection!" message:@"Error" preferredStyle:UIAlertControllerStyleAlert]; 
         UIAlertAction *ok=[UIAlertAction actionWithTitle:@"OK" style:UIAlertActionStyleDefault handler:nil]; 
         [alert addAction:ok]; 
         [self presentViewController:alert animated:YES completion:nil]; 
        } else { 


         // [HUD show:NO]; 
         [HUD setHidden:yes]; 

         NSLog(@"%@ %@", response, responseObject); 

        } 
       }]; 

[uploadTask resume];

//对于Objective-C代码 - 转换的UIImage到NSData的 // ---- //注：在PHP侧做编码转换JSON字符串到图像，easiliy在谷歌 // ---

NSData *data1 = UIImageJPEGRepresentation(imgProfileView.image,0.8); //0.1 to 1.0 upto image resolution 

NSString *encodedString1 = [data1 base64EncodedStringWithOptions:NSDataBase64EncodingEndLineWithLineFeed]; 

NSMutableDictionary *dicImage=[[NSMutableDictionary alloc] init]; 
[dicImage setObject:encodedString1 forKey:@"image1"]; 
[dicImage setObject:[dic valueForKey:@"des1"] forKey:@"des1"]; // if added any extra filed then 

NSMutableDictionary *dic_set_Sync=[[NSMutableDictionary alloc] init]; 
[dic_set_Sync setObject:APPDELEGATE.strEmailId forKey:@"email"]; 
[dic_set_Sync setObject: dicImage forKey:@"compressor_sync"]; 


NSError *error = nil; 
NSData *data = [NSJSONSerialization dataWithJSONObject:dic_set_Sync options:0 error:&error]; 
NSString *string = [[NSString alloc] initWithData:data encoding:NSUTF8StringEncoding]; 
if (error) 
    NSLog(@"%s: JSON encode error: %@", __FUNCTION__, error); 

NSURL *url = [NSURL URLWithString:@"https://www.inspectab.com/app/webservice/offline/compressor_syc.php"]; 
NSMutableURLRequest *request = [NSMutableURLRequest requestWithURL:url]; 

[request setHTTPMethod:@"POST"]; 
NSString *params = [NSString stringWithFormat:@"json=%@", 
        [string stringByAddingPercentEscapesUsingEncoding:NSUTF8StringEncoding]]; 

NSData *paramsData = [params dataUsingEncoding:NSUTF8StringEncoding]; 
[request addValue:@"8bit" forHTTPHeaderField:@"Content-Transfer-Encoding"]; 
[request addValue:@"application/x-www-form-urlencoded" forHTTPHeaderField:@"Content-Type"]; 
[request setHTTPBody:paramsData]; 

NSURLResponse *response = nil; 
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:&response error:&error]; 

if (error) 
    NSLog(@"%s: NSURLConnection error: %@", __FUNCTION__, error); 

// examine the response 

NSString *responseString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding]; 
NSLog(@"responseString: %@",responseString); 

if(![responseString isEqualToString:@""]) 
{ 
    NSDictionary *dicResponse = [NSJSONSerialization JSONObjectWithData:returnData 
                   options:kNilOptions error:&error]; 

    NSLog(@"dicResponse: %@", dicResponse);
