将图像上传到远程服务器，iPhone [英] Uploading images to Remote Server, iPhone

问题描述

我想从图书馆或照相机中获取图像，然后将其上传到远程服务器，然后我可以在其中检索每个上传图像的URL.

I would like to take images from library, or camera and upload them to a remote server, where I could then retreieve a URL for each image uploaded.

我希望从头开始.并且正在寻找从何处开始的帮助.

Im looking to get started from scratch. And am looking for some help on where to start.

我需要用最简单的方法做到这一点，即php和mysql. 我应该从哪里开始?！

推荐答案

哇，我很摇滚！

还有这个家伙. http://iphone.zcentric.com /2008/08/29/post-a-uiimage-to-the-web/

这里是我实现的

UIImage *myImage = [UIImage imageNamed:@"foo.png"];
NSData *imageData = UIImagePNGRepresentation(myImage);
// setting up the URL to post to
NSString *urlString = @"myurl/insert.php";

// setting up the request object now
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"];

/*
 now lets create the body of the post
 */
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"ipodfile.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);

对于PHP来说，它看起来像.

As for the PHP it looks like.

   <?php
       $uploaddir = './uploads/';
   $file = basename($_FILES['userfile']['name']);
   $uploadfile = $uploaddir . $file;

  if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
        echo "myurl/uploads/{$file}";
      } 
?>
