【问题描述】：

我有一个脚本，目前可以从互联网上传保存的图片或屏幕截图。但是，使用 iPhone 相机拍摄的任何照片都无法上传。为什么会这样？是内存问题吗？

<?php
$uploaddir = './upload/';
$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir . $file;
if (is_uploaded_file($_FILES['userfile']['tmp_name']))
{
if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile))
{
    echo "yes";
}
}
else
{
echo $_FILES['userfile']['error']; //just returns "1"

}
?>

这里是 iOS：

 NSUserDefaults *defaujez = [NSUserDefaults standardUserDefaults];
    NSString *rambli = [defaujez objectForKey:@"getpicforfu"];      


    NSData *imageData =UIImageJPEGRepresentation(imageView.image, 90);
    NSString *imgPath= @"http://www.mywebsite.com/script.php";

        NSString *filenames = rambli;
        NSLog(@"%@", filenames);
        NSString *urlString = imgPath;

        NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease];
        [request setURL:[NSURL URLWithString:urlString]];
        [request setHTTPMethod:@"POST"];

        NSString *boundary = @"---------------------------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 stringWithFormat:@"Content-Disposition: form-data; name=\"filenames\"\r\n\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
        [body appendData:[filenames dataUsingEncoding:NSUTF8StringEncoding]];

        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"userfile\"; filename=\"%@.jpg\"\r\n", rambli] dataUsingEncoding:NSUTF8StringEncoding]];

       // [body appendData:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\".jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];

        [body appendData:[@"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];
        if([returnString isEqualToString:@"yes"])
        {
             [self finitop];

        }
        else {
            [spinner stopAnimating];
            rambolrqa.text = @"Posted Empty Because Upload Failed";

        }

【问题讨论】：

您无需检查上传是否成功。在$_FILES 中有一个['error'] 参数是有原因的：php.net/manual/en/features.file-upload.errors.php
上传不成功。我去了服务器位置并检查了。它不在那里。
所以检查['error'] 找出它失败的原因。
我不断收到返回值作为意外 [.这很可能与['error']有关。有没有其他方法可以获取返回值？
我将错误症状更改为 echo $_FILES['userfile']['error'];，它刚刚返回 1。

【解决方案1】：

这通过在 iOS 上将其压缩到合理的大小来解决。

NSData *imageDataf = [[NSData alloc] initWithData:UIImageJPEGRepresentation((imageView.image), 0.5)];
int imageSize = imageDataf.length;

if (imageSize >50000) {
    //35414 normal
    //952683 camera
    if (imageSize >2000000) {
NSData *imgData= UIImageJPEGRepresentation(imageView.image,0.00001);
UIImage *image=[UIImage imageWithData:imgData];
imageView.image = image;
    }
    else {
        NSData *imgData= UIImageJPEGRepresentation(imageView.image,0.001);
        UIImage *image=[UIImage imageWithData:imgData];
        imageView.image = image;
    }
}
