我无论如何都想不出为什么在使用AFNetworking时这个功能不能正常工作。但是在使用ASIHTTP时它是可以正常工作的。这对我来说都很新颖,但是我无法弄清楚为什么文件不再从$_FILES传输到服务器的硬盘上了。以下是iOS代码:
- (IBAction)uploadPressed
{
[self.fileName resignFirstResponder];
NSURL *remoteUrl = [NSURL URLWithString:@"http://mysite.com"];
NSTimeInterval timeInterval = [NSDate timeIntervalSinceReferenceDate];
NSString *photoName=[NSString stringWithFormat:@"%lf-Photo.jpeg",timeInterval];
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
// the path to write file
NSString *filePath = [documentsDirectory stringByAppendingPathComponent:photoName];
NSData * photoImageData = UIImageJPEGRepresentation(self.remoteImage.image, 1.0);
[photoImageData writeToFile:filePath atomically:YES];
NSLog(@"photo written to path: e%@", filePath);
AFHTTPClient *httpClient = [[AFHTTPClient alloc] initWithBaseURL:remoteUrl];
NSMutableURLRequest *afRequest = [httpClient multipartFormRequestWithMethod:@"POST"
path:@"/photos"
parameters:nil
constructingBodyWithBlock:^(id <AFMultipartFormData>formData)
{
[formData appendPartWithFormData:[self.fileName.text dataUsingEncoding:NSUTF8StringEncoding]
name:@"name"];
[formData appendPartWithFileData:photoImageData
name:self.fileName.text
fileName:filePath
mimeType:@"image/jpeg"];
}
];
AFHTTPRequestOperation *operation = [[AFHTTPRequestOperation alloc] initWithRequest:afRequest];
[operation setUploadProgressBlock:^(NSInteger bytesWritten, NSInteger totalBytesWritten, NSInteger totalBytesExpectedToWrite) {
NSLog(@"Sent %d of %d bytes", totalBytesWritten, totalBytesExpectedToWrite);
}];
[operation setCompletionBlock:^{
NSLog(@"%@", operation.responseString); //Gives a very scary warning
}];
[operation start];
}
我曾经这样做:
ASIFormDataRequest *request = [ASIFormDataRequest requestWithURL:remoteUrl];
[request setPostValue:self.fileName.text forKey:@"name"];
[request setFile:filePath forKey:@"filename"];
[request setDelegate:self];
[request startAsynchronous];
以下是我的 PHP 代码:
{
// these could be stored in a .ini file and loaded
// via parse_ini_file()... however, this will suffice
// for an example
$codes = Array(
100 => 'Continue',
101 => 'Switching Protocols',
200 => 'OK',
201 => 'Created',
202 => 'Accepted',
203 => 'Non-Authoritative Information',
204 => 'No Content',
205 => 'Reset Content',
206 => 'Partial Content',
300 => 'Multiple Choices',
301 => 'Moved Permanently',

501 => 'Not Implemented',
502 => 'Bad Gateway',
503 => 'Service Unavailable',
504 => 'Gateway Timeout',
505 => 'HTTP Version Not Supported'
);
return (isset($codes[$status])) ? $codes[$status] : '';
}
function sendResponse($status = 200, $body = '', $content_type = 'text/html')
{
$status_header = 'HTTP/1.1 ' . $status . ' ' . getStatusCodeMessage($status);
header($status_header);
header('Content-type: ' . $content_type);
echo $body;
}
if (!empty($_FILES) && isset($_POST["name"])) {
$name = $_POST["name"];
$tmp_name = $_FILES['filename']['tmp_name'];
$uploads_dir = '/var/www/cnet/photos';
move_uploaded_file($tmp_name, "$uploads_dir/$name.jpg");
$result = array("SUCCEEDED");
sendResponse(200, json_encode($result));
} else {
sendResponse(400, 'Nope');
}
?>
!empty($_FILES)
而不是isset($_FILES)
,并且$_FILES['filename']['tmp_name']
将返回上传文件的完整路径,因此move_uploaded_file
将无法工作。如果你在php文件顶部添加了error_reporting(E_ALL)
,那么你就会看到错误信息... - Lawrence Cherone
