我的程序是为从摄像头上传图片而编写的，示例代码如下：
#define WEBSERVICE_URL @"http://192.168.0.104/upload.php"
- (void)imagePickerController:(UIImagePickerController *)picker didFinishPickingMediaWithInfo:(NSDictionary *)info {
[picker dismissViewControllerAnimated:YES completion:^{
UIImage *selectedImage = [info objectForKey:UIImagePickerControllerOriginalImage];
NSData *imageData = UIImagePNGRepresentation(selectedImage);
NSMutableURLRequest *request = [[AFHTTPRequestSerializer serializer] multipartFormRequestWithMethod:@"POST" URLString:WEBSERVICE_URL parameters:nil constructingBodyWithBlock:^(id formData) {
[formData appendPartWithFileData:imageData name:@"upfile" fileName:@"test" mimeType:@"image/png"];
} error:nil];
AFURLSessionManager *manager = [[AFURLSessionManager alloc] initWithSessionConfiguration:[NSURLSessionConfiguration defaultSessionConfiguration]];
NSProgress *progress = nil;
NSURLSessionUploadTask *uploadTask = [manager uploadTaskWithStreamedRequest:request progress:&progress completionHandler:^(NSURLResponse *response, id responseObject, NSError *error) {
[progress removeObserver:self forKeyPath:@"fractionCompleted"];
NSLog(error.debugDescription);
if (error) {
[self.view updateWithMessage:[NSString stringWithFormat:@"Error : %@!", error.debugDescription]];
} else {
[self.view updateWithMessage:@"Great success!"];
}
}];
[progress addObserver:self forKeyPath:@"fractionCompleted" options:NSKeyValueObservingOptionNew context:NULL];
[uploadTask resume];
self.imageUploadProgress = [[TNSexyImageUploadProgress alloc] init];
self.imageUploadProgress.radius = 100;
self.imageUploadProgress.progressBorderThickness = -10;
self.imageUploadProgress.trackColor = [UIColor blackColor];
self.imageUploadProgress.progressColor = [UIColor whiteColor];
self.imageUploadProgress.imageToUpload = selectedImage;
[self.imageUploadProgress show];
[[NSNotificationCenter defaultCenter] addObserver:self selector:@selector(imageUploadCompleted:) name:IMAGE_UPLOAD_COMPLETED object:self.imageUploadProgress];
}];
}
错误是：
TNSexyImageUploadProgressDemo[5275:113032] Error Domain=NSURLErrorDomain Code=-1001 "The operation couldn’t be completed. (NSURLErrorDomain error -1001.)" UserInfo=0x7f92c2d907d0 {NSErrorFailingURLStringKey="http://192.168.0.104/upload.php", NSUnderlyingError=0x7f92c2dcd5c0 "The operation couldn’t be completed. (kCFErrorDomainCFNetwork error -1001.)", NSErrorFailingURLKey="http://192.168.0.104/upload.php"}
无论在模拟器或 iPhone 上，同样的错误，我使用 safari 访问 url，一切都是正确的，我使用 wifi 访问网络。ping 192.168.0.104 没问题。
服务器的程序是用php编写的，代码如下：
100000000) {
$result_json['error'] = 'Exceeded filesize';
}
$finfo = new finfo(FILEINFO_MIME_TYPE);
if (false === $ext = array_search(
$finfo->file($_FILES['upfile']['tmp_name']),
array(
'png' => 'image/png'
),
true
)) {
$result_json['error'] = 'Invalid file format';
}
if (!move_uploaded_file(
$_FILES['upfile']['tmp_name'],
sprintf('./uploads/%s.%s',
sha1_file($_FILES['upfile']['tmp_name']),
$ext
)
)) {
$result_json['error'] = 'Failed to move uploaded file';
}
// send the result now
echo json_encode($result_json);
/*
try {
if (!move_uploaded_file(
$_FILES['upfile']['tmp_name'],
sprintf('./uploads/%s.%s',
sha1_file($_FILES['upfile']['tmp_name']),
$ext
)
)) {
//throw new RuntimeException('Failed to move uploaded file.');
}
//echo json_encode(array('succes'=>true));
} catch (RuntimeException $e) {
//echo $e->getMessage();
}
*/
?>
