【问题标题】:upload image from iphone to the server folder将图像从 iphone 上传到服务器文件夹
【发布时间】:2010-12-28 16:50:16
【问题描述】:

我发现网上很少有 sn-p 将图像从 iphone 上传到服务器文件夹,它显示使用服务器端脚本,例如。在服务器端使用 php

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

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
        echo "Uploaded!";
}else{
   echo "Not Uploaded!";
}
/>

是否有可能不使用上述代码直接将图像上传到服务器文件夹,

假设我想上传到http://111.22.333.44/mysite/pics/ 不带任何服务器端脚本,如果可以的话怎么做

    /*
      turning the image into a NSData object
      getting the image back out of the UIImageView
      setting the quality to 90
     */
     NSData *imageData = UIImageJPEGRepresentation(image.image, 90);
     // setting up the URL to post to
     NSString *urlString = @"http://iphone.zcentric.com/test-upload.php";
    
     // setting up the request object now
     NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
     [request setURL:[NSURL URLWithString:urlString]];
     [request setHTTPMethod:@"POST"];
    
     /*
      add some header info now
      we always need a boundary when we post a file
      also we need to set the content type
    
      You might want to generate a random boundary.. this is just the same 
      as my output from wireshark on a valid html 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);
    

    此代码将对您有所帮助....

    • 我必须删除与 application/octet-stream 的行以使其与 attachment_fu 一起使用。任何想法为什么?
    • 这是很棒的代码。第一次为我工作。谢谢parvind :)
    • 注意上传文件的大小。您正在使用内存中整个文件的内容创建请求,然后发送它......如果文件太大(或者您同时上传许多文件),您可能会遇到内存消耗问题
    【解决方案2】:

    如果您设置您的网络服务器以允许 PUT 方法,您可以这样做。 99% 的 Web 服务器只允许使用 GET 和 POST 方法。

    我从来没有这样做过,我不能给你太多帮助。这是我从谷歌那里得到的一个页面:
