Question

嗯，我对iphone和PHP开发都很陌生，我试图在本地将图像发布到我的网络服务器上（我已经设置了网络服务器）。出于某种原因，我的PHP脚本正在执行，但文件没有被保存。

我确信这是最基本的问题，但我似乎无法找到问题所在。真的很感谢你们的帮助。谢谢！

我的目标-c代码：

UIImageView *imageView = [[UIImageView alloc] init];
imageView.image = [UIImage imageNamed:@"13.png"];

NSData *imageData = UIImageJPEGRepresentation(imageView.image, 90);
NSString *urlString = @"http://localhost/uploader.php";
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]init];
[request setTimeoutInterval:60.0];
[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:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

[body appendData:[[NSString stringWithString:@"Content-Disposition: form-data; name=\"userfile\";filename=\"myfile.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]];

[request setHTTPBody:body];
NSLog(@"%@",[[NSString alloc] initWithData:[NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil] encoding:NSUTF8StringEncoding]);

我的PHP脚本：

<?php
$target = "./upload/";
$target = $target.basename( $_FILES['userfile']['name']) ;
$check = getimagesize($_FILES['userfile']['tmp_name']);

if (move_uploaded_file($_FILES['userfile']['tmp_name'], './upload/')) {
    echo "YES";
}
 else
  echo "NO";

?>

这些是我在PHP中打印这些变量时得到的值：

print_r($target);

./upload/myfile.jpg

print_r($check[0]);

320

print_r($_REQUEST);

Array
(
)


print_r($_FILES[userfile]);

Array
(
    [name] => myfile.jpg
    [type] => application/octet-stream
    [tmp_name] => /private/var/tmp/phpWJE4UC
    [error] => 0
    [size] => 8829
)

print_r($_FILES[name]): 

(empty)

print_r($_FILES[type]);

(empty)

print_r($_FILES[tmp_name]);

(empty)

print_r($_FILES[error]);

(empty)

print_r($_FILES[size]);

(empty)

print_r($_FILES);


Array
(
    [userfile] => Array
        (
            [name] => myfile.jpg
            [type] => application/octet-stream
            [tmp_name] => /private/var/tmp/phpMvJ4oR
            [error] => 0
            [size] => 8829
        )

)

您的移动电话不正确。您必须为目标指定文件名。您只提供了一个目录，因此调用失败。 PHP不会为您创建文件名，您必须自己指定。

if (move_uploaded_file($_FILES['userfile']['tmp_name'], './upload/name_of_file_to_write')) {
                                                                  ^^^^^^^^^^^^^^^^^^^^^
