Question

早上好，

我尝试使用Objective-C和PHP文件上传图像，但我得到了一个＆＃34;注意：未定义的索引：userfile＆＃34;来自我的PHP。我尝试了很多事情，但我不知道我的错误在哪里，这就是我需要你帮助的原因。我将发布我的代码。

CamViewController.m

- (IBAction)uploadPhoto:(UIButton *)sender {

    NSData *imageData = UIImageJPEGRepresentation(_imageView.image, 90);
    NSString *urlString = @"http://www.mywebsite.com/upload.php";

    NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
    [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:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\"imagen.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]];
    [request setHTTPBody:body];

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

    NSLog(returnString);

}

CamViewController.h

@interface CamViewController : UIViewController <UIImagePickerControllerDelegate, UINavigationControllerDelegate>

@property (strong, nonatomic) IBOutlet UIImageView *imageView;

- (IBAction)takePhoto:  (UIButton *)sender;

- (IBAction)selectPhoto:(UIButton *)sender;

- (IBAction)uploadPhoto:(UIButton *)sender;

@end

输出错误：

Incorrect file type.   is the file type you uploaded.

PHP文件：

<?php
print_r($_REQUEST);
error_reporting(E_ALL);
ini_set("display_errors", 1);

$uploaddir = '/images/';      //Uploading to same directory as PHP file
$file = basename($_FILES['userfile']['name']);
$uploadfile = $uploaddir . $file;

if (is_uploaded_file($_FILES['userfile']['tmp_name']))
{
    echo "Temp file uploaded. \r\n";
}
else
{
    echo "Temp file not uploaded. \r\n";
}

if ((!($_FILES['userfile']['type'] == "image/jpeg")) && (!($_FILES['userfile']['type']    == "image/png")))           
{
    exit("Incorrect file type.  " . $_FILES['userfile']['type'] . " is the file type you uploaded."); 
}


if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile)) {
    $postsize = ini_get('post_max_size');   
    $canupload = ini_get('file_uploads');    
    $tempdir = ini_get('upload_tmp_dir');   
    $maxsize = ini_get('upload_max_filesize');
    echo "http://www.mywebsite.com/images/{$file}" . "\r\n" . $_FILES['userfile']['size'] . "\r\n" . $_FILES['userfile']['type'] ;
}
?>

你能帮助我吗？我不知道错误在哪里。

快照未呈现的视图会导致空快照。确保在屏幕更新后快照或快照之前，您的视图至少呈现过一次。

提前致谢。

注意：未定义索引：用PHP文件的用户文件Objective-C
