I’m making an attempt to add a textual content file to an internet server from an iOS software. I’ve written an goal C methodology to deal with the add request and a PHP file to deal with the POST request on the server. I’ve additionally written a small HTML web page to check the add from a browser (which is working superb utilizing the identical PHP file). When the iOS App runs it ought to add a textual content file (which is empty ie 0 bytes in dimension) to a specified folder on the internet server, and though the debug window exhibits the response as success(200) the file will not be uploaded.
Right here is the Goal C methodology
+ (void)fileUpload{
NSString *localFilePath = [self GetTokenFilePath];
NSURL *localFile = [NSURL fileURLWithPath:localFilePath];
NSData *knowledge = [[NSData alloc] initWithContentsOfFile:localFilePath];
NSString *filename = [self GetTokenFilename];
// Arrange the physique of the POST request.
// This boundary serves as a separator between one type subject and the following.
// It should not seem anyplace throughout the precise knowledge that you simply intend to
// add.
NSString * boundary = @"---------------------------14737809831466499882746641449";
// Physique of the POST methodology
NSMutableData * physique = [NSMutableData data];
// The physique should begin with the boundary preceded by two hyphens, adopted
// by a carriage return and newline pair.
//
// Discover that we prepend two further hyphens to the boundary when
// we truly use it as a part of the physique knowledge.
//
[body appendData:[[NSString stringWithFormat:@"rn--%@rn",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// That is adopted by a sequence of headers for the primary subject after which
// TWO CR-LF pairs. set tag-name to submit add
[body appendData:[[NSString stringWithFormat:@"Content-Disposition: form-data; name="file"; filename="%@.txt"rn", filename] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: application/octet-streamrnrn" dataUsingEncoding:NSUTF8StringEncoding]];
// Subsequent is the precise knowledge for that subject (referred to as "tag_name") adopted by
// a CR-LF pair, a boundary, and one other CR-LF pair.
[body appendData:[NSData dataWithData:data]];
// Shut the request physique with one final boundary with two
// further hyphens prepended **and** two further hyphens appended.
[body appendData:[[NSString stringWithFormat:@"rn--%@--rn", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// Knowledge importing activity.
NSURL * url = [NSURL URLWithString:@"https://MY_URL.co.uk/Upload.php"];
NSMutableURLRequest * request = [NSMutableURLRequest requestWithURL:url];
NSString * contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];
request.HTTPMethod = @"POST";
request.HTTPBody = physique;
/*------------------*/
NSURLSession *session = [NSURLSession sharedSession];
// Create a NSURLSessionUploadTask object to Add knowledge for a jpg picture.
NSURLSessionUploadTask *activity = [session uploadTaskWithRequest:request fromFile:localFile completionHandler:^(NSData * _Nullable data, NSURLResponse * _Nullable response, NSError * _Nullable error) {
if (error == nil) {
// Upload success.
NSLog(@"upload file：%@",localFile);
NSLog(@"upload success：%@",[[NSString alloc] initWithData:knowledge encoding:NSUTF8StringEncoding]);
NSLog(@"add response：%@",response);
// Replace person defaults to indicate success on token add.
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:TRUE forKey:@"TOKEN_UPLOAD_SUCCESS"];
} else {
// Add fail.
NSLog(@"add error:%@",error);
NSLog(@"add response：%@",response);
// Replace person defaults to indicate success on token add.
NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults];
[defaults setBool:FALSE forKey:@"TOKEN_UPLOAD_SUCCESS"];
}
}];
[task resume];
}
Right here is the PHP file I exploit on the server finish
<?php
print_r($_POST);
echo "<br>";
//phpinfo();
// file properties
$file = $_FILES['file'];
$file_name = $_FILES['file']['name'];
$file_tmp = $_FILES['file']['tmp_name'];
$file_size = $_FILES['file']['size'];
$file_error = $_FILES['file']['error'];
$file_type = $_FILES['file']['type'];
echo "File title = ".$file_name."<br>";
echo "File dimension = ".$file_size."<br>";
echo "File error = ".$file_error."<br>";
//print_r($file);
//work out the file extension
$file_ext = explode('.' , $file_name );
$file_actual_ext = strtolower(finish($file_ext));
echo "File Extension = ".$file_actual_ext."<br>";
//echo $file_actual_ext;
$allowed = array('txt', 'csv');
print_r($allowed);
echo "<br>";
if(in_array($file_actual_ext,$allowed)) {
echo "File sort is allowed"."<br>";
if($file_error === 0) {
if($file_size <= 1048576) {
$file_destination = "TokensV11/".$file_name;
echo "File Vacation spot = ".$file_destination."<br>";
if(move_uploaded_file($file_tmp, $file_destination)) {
echo "The file has been uploaded sucessfully"."<br>";
}else{
echo "The file was not moved to vacation spot"."<br>";
}
}else{
echo "The file dimension is just too giant"."<br>";
}
}else{
echo "There was an error importing your file"."<br>";
}
}else {
echo "You can't add recordsdata of this kind or no file was specified"."<br>";
}
?>
Right here is the output pattern from the debug window in Xcode
