Description of my problem is actually in question header. I'm new with web technologies, so this behaviour is for me a little striking. Why failure block is called although image upload has been completed with success? Moreover I searched an answer for my question on SoF and applied some solutions, but this error still is appearing. Please help if possible. Thank you in advance.
OBJECTIVE - C:
- (void)upload {
NSString *fileName = [NSString stringWithFormat:@"%ld%c%c.jpg", (long)[[NSDate date] timeIntervalSince1970], arc4random_uniform(26) + 'a', arc4random_uniform(26) + 'a'];
NSString *imagePath = [[NSBundle mainBundle] pathForResource:@"image" ofType:@"jpg"];
NSData *data = UIImagePNGRepresentation([UIImage imageWithContentsOfFile:imagePath]);
NSString *URLString = @"http://myServer/myAppFolder";
AFHTTPRequestOperationManager *manager = [[AFHTTPRequestOperationManager manager] initWithBaseURL:[NSURL URLWithString:URLString]];
AFJSONResponseSerializer *responseSerializer = [AFJSONResponseSerializer serializerWithReadingOptions:NSJSONReadingAllowFragments];
[manager setResponseSerializer:responseSerializer];
[manager.responseSerializer setAcceptableContentTypes:[NSSet setWithObject:@"text/html"]];
AFHTTPRequestOperation *operation = [manager POST:@"upload.php" parameters:nil constructingBodyWithBlock:^(id<AFMultipartFormData> formData) {
[formData appendPartWithFileData:data name:@"uploadedfile" fileName:fileName mimeType:@"image/jpeg"];
} success:^(AFHTTPRequestOperation *operation, id responseObject) {
NSLog(@"Success %@", responseObject);
} failure:^(AFHTTPRequestOperation *operation, NSError *error) {
NSLog(@"Failure / %@, / %@", error, operation.responseString); //error comes from here
}];
[operation setUploadProgressBlock:^(NSUInteger bytesWritten, long long totalBytesWritten, long long totalBytesExpectedToWrite) {
NSLog(@"uploading...");
}];
}
upload.php:
<?php
$filename="uploaded";
$target_path = "uploads/";
$target_path = $target_path . basename( $_FILES['uploadedfile']['name']);
if(move_uploaded_file($_FILES['uploadedfile']['tmp_name'], $target_path)) {
echo "The file ". basename( $_FILES['uploadedfile']['name'])." has been uploaded";
} else {
echo "There was an error uploading the file, please try again!";
}
?>;
I'm getting this error:
Failure / Error Domain=NSCocoaErrorDomain Code=3840 "The operation couldn’t be completed. (Cocoa error 3840.)" (Invalid value around character 0.) UserInfo=0x8a633e0 {NSDebugDescription=Invalid value around character 0.}, / The file 1389046572lb.jpg has been uploaded;
It seems that the problem is in the fact that you are using AFJSONResponseSerializer
to serialize the response of your PHP upload script.
And your PHP is not returning a JSON - thus serializer throws an error.
You could either modify PHP script so that it returns a JSON formatted result. Or you can use different type of serializer.
According to this forum solution would be to use [AFResponseSerializer serializer]
- i'm not sure if it even exists. Try basic AFHTTPResponseSerializer
.
