Question

我在将文件上传到http服务器时遇到错误。这是我正在使用的代码：

    UIImage * ourImage = [UIImage imageNamed:@"tux.png"];
    NSData * imageData = UIImageJPEGRepresentation(ourImage, 1.0);  

    NSString *urlString = @"http://www.site.com/imageupload.php";      
    NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
    [request setURL:[NSURL URLWithString:urlString]];
    [request setHTTPMethod:@"POST"];

    NSMutableData *body = [NSMutableData data];


    NSString *boundary = [NSString stringWithString:@"---------------------------14737809831466499882746641449"];
    NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
    [request addValue:contentType forHTTPHeaderField:@"Content-Type"];



    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"Content-Disposition: attachment; name=\"userfile\"; filename=\".png\"\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 stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

    // Text parameter1
    NSString *param1 = @"parameter text";
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"parameter1\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:param1] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

    // Another text parameter
    NSString *param2 = @"Parameter 2 text";
    [body appendData:[[NSString stringWithFormat:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"parameter2\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:param2] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithString:@"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];

    // close form
    [body appendData:[[NSString stringWithFormat:@"--%@--\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]];

    // set request body
    [request setHTTPBody:body];

    //return and test
    NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
    NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];

    NSLog(@"%@", returnString);

这是我在服务器的public_html /目录中的PHP文件。文件名是imageupload.php。我试图通过HTTP上传图像文件而不使用任何登录名或密码。我不熟悉PHP，真的需要一些帮助。感谢。

    <?php
     $uploaddir = '/public_html/upload';
     $file = basename($_FILES['userfile']['name']);
     $uploadFile = $file;
     $randomNumber = rand(0, 99999);
     $newName = $uploadDir . $uploadFile;
    if (is_uploaded_file($_FILES['userfile']['tmp_name'])) {
    echo "Temp file uploaded. \r\n";
    } else {
    echo "Temp file not uploaded. \r\n";
   }

   if (move_uploaded_file($_FILES['userfile']['tmp_name'], $newName)) {
         $postsize = ini_get('post_max_size'); //Not necessary, I was using these
         $canupload = ini_get('file_uploads'); //server variables to see what was 
         $tempdir = ini_get('upload_tmp_dir'); //going wrong.
         $maxsize = ini_get('upload_max_filesize');
         echo "http://www.iroboticshowoff.com/dir/{$file}" . "\r\n" .  $_FILES['userfile']
         ['size'] . "\r\n" . $_FILES['userfile']['type'] ;
    }
    ?>

这是我执行代码时从服务器返回的错误：

解析错误：语法错误， /home/a5054180/public_html/imageupload.php 中的意外T_STRING 2

加上其他错误。任何人都可以试一试，让我知道我能做些什么来解决它。我非常感谢，非常感谢。

我没有测试过您的脚本，但我认为您应该将Content-Disposition和Content-Type更改为：

内容 - 处置：表单数据; NAME = “userfile的”;文件名= “front.png” 内容类型： image / png

你知道查尔斯的节目吗？这非常有帮助。它是一个代理，可以帮助您分析您的请求以及服务器响应。
