如何将文件目录中的图像文件上传到iphone中的php服务器 [英] how to upload image file from document directory to php server in iphone

问题描述

我目前正在开发类似iPhone的应用程序。根据我的要求，我需要将所有摄像头捕获的图像存储到文档目录中。文档文件夹中有大约10-20个图像文件，之后我必须使用单个php URL在服务器上推送该应用程序资源文档文件夹。我附上了用于显示包含一些图像文件的资源文件夹的屏幕截图。

这是我的PHP代码：

  $ file_path =../ Gallery /; 
 
 $ file_path = $ file_path。 basename（$ _FILES ['Documents'] ['name']）; 
 if（move_uploaded_file（$ _ FILES ['Documents'] ['tmp_name']，$ file_path））{
 echoImage is upload; 
} else {
 echo图片不上传; 
} 
  

有人可以帮助我如何上传php服务器上的文件夹？

提前致谢。

解决方案

你需要使用/来电用于完成此操作的递归函数中的API。

Serverside Code

  //在服务器中创建一个名为images的文件夹，用于上传图像。 
 //并创建一个PHP文件并使用下面的代码。 
 
 
<？php 
 $ uploaddir ='images /'; 
 $ ran = rand（）; 
 
 $ file = basename（$ _ FILES ['userfile'] ['name']）; 
 $ uploadfile = $ uploaddir。$ ran。$ file; 
 
 if（move_uploaded_file（$ _ FILES ['userfile'] ['tmp_name']，$ uploadfile））{
 echowww.host.com/.../images/{$上传文件}; 
} 
？> 
  

申请方代码

   - （IBAction）uploadClicked：（id）sender 
 {
 
 [self UploadTheImageNow：0] ; 
 
} 
  

以下代码用于递归函数，该函数将持续到所有图片上传都将完成。

   - （void）UploadTheImageNow：（NSInteger）count 
 {
 
 // UIImage * updatedImage = [UIImage ImageNamed：@您的图像名称/您可以从数组中获取]; 
 UIImage * updatedImage = [UIImage ImageNamed：[yourArray ObjectAtIndex：ic]]; 
 NSData * imageData = UIImageJPEGRepresentation（updatedImage，90）; 
 NSString * urlString = @你的URL链接; 
 NSMutableURLRequest * request = [[[NSMutableURLRequest alloc] init] autorelease]; 
 [request setURL：[NSURL URLWithString：urlString]]; 
 [请求setHTTPMethod：@POST]; 
 
 
 NSString * boundary = [NSString stringWithString：@--------------------------- 14737809831466499882746641449 ]; 
 NSString * contentType = [NSString stringWithFormat：@multipart / form-data; boundary =％@，boundary]; 
 [请求addValue：contentType forHTTPHeaderField：@Content-Type]; 
 NSMutableData * body = [NSMutableData data]; 
 [body appendData：[[NSString stringWithFormat：@rn  - ％@ rn，boundary] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [body appendData：[[NSString stringWithString：@Content-Disposition：form-data; name =userfile; filename =ipodfile.jpgrn] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [body appendData：[[NSString stringWithString：@Content-Type：application / octet-streamrnrn] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [body appendData：[NSData dataWithData：imageData]]; 
 [body appendData：[[NSString stringWithFormat：@rn  - ％@  -  rn，boundary] dataUsingEncoding：NSUTF8StringEncoding]]; 
 [请求setHTTPBody：body]; 
 
 
 [NSURLConnection sendAsynchronousRequest：请求队列：[NSOperationQueue mainQueue] 
 completionHandler：^（NSURLResponse *响应，NSData *数据，NSError *错误）
 {
 if（[（NSHTTPURLResponse *）response statusCode] == 200）
 {
 id jsonObject = [NSJSONSerialization JSONObjectWithData：data options：NSJSONReadingAllowFragments error：nil]; 
 NSLog（@使用jsonObject％@完成，jsonObject）; 
 count ++; 
 if（count< 20）
 {
 [self UploadTheImageNow：count]; 
} 
其他
 {
 //已完成上传所有图片
} 
 
} 
 
}]; 
 
 
} 
  

I am currently working on gallery kind of iPhone application. According to my requirement, i need to store all the camera captured image into document directory. there is some 10-20 image files in document folder and after that i have to push that application resource document folder on server using single php url. I have attached screenshot for displaying resource folder with some image files.

here is my PHP Code :

  $file_path = "../Gallery/";

   $file_path = $file_path . basename( $_FILES['Documents']['name']);
   if(move_uploaded_file($_FILES['Documents']['tmp_name'], $file_path)) {
       echo "Image is upload";
   } else{
       echo "Image is not Upload";
   }

Can someone help me how can i upload document folder on php server ?

Thanks in advance.

解决方案

You need to use/ call the API in a recursive function to get this done.

Serverside Code

//Create a folder named images in your server where you want to upload the image.
 // And Create a PHP file and use below code .


 <?php
 $uploaddir = 'images/';
 $ran = rand () ;

 $file = basename($_FILES['userfile']['name']);
 $uploadfile = $uploaddir .$ran.$file;

 if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
 echo "www.host.com/.../images/{$uploadfile}";
 }
 ?>

Application Side code

 - (IBAction)uploadClicked:(id)sender
 {

 [self  UploadTheImageNow:0];

 }

The below code is for the recursive function which will continue till all the image upload will get finish.

-(void)UploadTheImageNow:(NSInteger)count
 {

 // UIImage *updatedImage=[UIImage ImageNamed:@" Your Image name / you can get from array"];
 UIImage *updatedImage=[UIImage ImageNamed:[yourArray ObjectAtIndex:ic]];
 NSData *imageData = UIImageJPEGRepresentation(updatedImage, 90);
 NSString *urlString = @"your URL link";
 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:@"rn--%@rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
 [body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name="userfile"; filename="ipodfile.jpg"rn"] dataUsingEncoding:NSUTF8StringEncoding]];
 [body appendData:[[NSString stringWithString:@"Content-Type: application/octet-streamrnrn"] dataUsingEncoding:NSUTF8StringEncoding]];
 [body appendData:[NSData dataWithData:imageData]];
 [body appendData:[[NSString stringWithFormat:@"rn--%@--rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
 [request setHTTPBody:body];


 [NSURLConnection sendAsynchronousRequest:request queue:[NSOperationQueue mainQueue]
 completionHandler:^(NSURLResponse *response, NSData *data, NSError *error)
 {
   if ([(NSHTTPURLResponse *)response statusCode]==200)
    {
      id jsonObject = [NSJSONSerialization JSONObjectWithData:data options:NSJSONReadingAllowFragments error:nil];
      NSLog(@"Finished with jsonObject %@", jsonObject);
      count++;
      if(count<20)
         {
           [self  UploadTheImageNow:count];
         }
        else
          {
            // Finished Uploading all Images
          }

    }

 }];


 }
