ios - 如何将图像上传到服务器

Question

我在ios中使用这些代码上传图片

与Internet上的另一个代码几乎相同

NSData *uploadImage = UIImageJPEGRepresentation(self.image, 1) ;
NSString *uploadURL = @"http://...../jeff.php" ;

NSMutableURLRequest *uploadRequest = [[NSMutableURLRequest alloc] init];
[uploadRequest setURL:[NSURL URLWithString:uploadURL]] ;
[uploadRequest setHTTPMethod:@"POST"] ;

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

NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Disposition:form-data; name=\"userfile\"; filename=\"test.jpg\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; 
[body appendData:[@"Content-Type: application/octet-streamrnrn\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:uploadImage]];
[body appendData:[[NSString stringWithFormat:@"--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];

[uploadRequest setHTTPBody:body];

NSData *returnData = [NSURLConnection sendSynchronousRequest:uploadRequest returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"echo：%@",returnString); 

我的PHP是

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

if (is_uploaded_file($_FILES['userfile']['tmp_name']))
{
    echo "yes \r\n";
}
else
{
    echo "NO \r\n";
}

if (move_uploaded_file($_FILES['userfile']['tmp_name'], $uploadfile))
{
    echo "http://...../uploads/{$file}";
}

但这没用

我的上传文件夹是/ var / www / uploads

FOR POST METHOD READ MY OWN ANSWER FROM.

并将此代码用于图像发布。

NSString  *imgPath = fullPathOfYourImage;
    if([[NSFileManager defaultManager] fileExistsAtPath:imgPath])
    {
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];                                                        
        [body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name=\"photo\"; filename=\"YourImageName.png\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]];
                                                                                                               ^..YourImageName….^

        [body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
        [body appendData:[NSData dataWithContentsOfFile:imgPath]];
        [body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
    }
