Use multipart/form-data
for header Content-Type
, and Content-Type: application/octet-stream
for a file in HTTP body.
OK, I will show u a demo, just create an new Xcode project with template 'Empty Application', check 'Use ARC', then paste :
#import "AppDelegate.h"
@interface AppDelegate ()
@property (nonatomic, strong) NSURLConnection *urlConnection;
@property (nonatomic, strong) NSMutableData *receivedData;
@end
@implementation AppDelegate
- (BOOL)application:(UIApplication *)application didFinishLaunchingWithOptions:(NSDictionary *)launchOptions
{
self.window = [[UIWindow alloc] initWithFrame:[[UIScreen mainScreen] bounds]];
[self.window makeKeyAndVisible];
NSString *localFile = [[NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES)
objectAtIndex:0] stringByAppendingPathComponent:@"user.sqlite"];
NSString *api = @"http://192.168.0.170/test/upload/upload.php";
[self sendFile:localFile toServer:api];
return YES;
}
- (void)sendFile:(NSString *)filePath toServer:(NSString *)serverURL
{
NSData *fileData = [NSData dataWithContentsOfFile:filePath];
if (!fileData) {
NSLog(@"Error: file error");
return;
}
if (self.urlConnection) {
[self.urlConnection cancel];
self.urlConnection = nil;
}
NSMutableURLRequest *request = [[NSMutableURLRequest alloc]
initWithURL:[NSURL URLWithString:serverURL]];
[request setTimeoutInterval:30.0];
[request setHTTPMethod:@"POST"];
NSString *boundary = @"780808070779786865757";
/* Header */
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@", boundary];
[request addValue:contentType forHTTPHeaderField:@"Content-Type"];
/* Body */
NSMutableData *postData = [NSMutableData data];
[postData appendData:[[NSString stringWithFormat:@"--%@
", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[[NSString stringWithFormat:@"Content-Disposition:form-data; name="file"; filename="test.sqlite"
"] dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:[@"Content-Type: application/octet-stream
" dataUsingEncoding:NSUTF8StringEncoding]];
[postData appendData:fileData];
[postData appendData:[[NSString stringWithFormat:@"
--%@--
", boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[request setHTTPBody:postData];
self.urlConnection = [NSURLConnection connectionWithRequest:request delegate:self];
}
- (void)connection:(NSURLConnection *)connection didReceiveResponse:(NSURLResponse *)response
{
if (self.receivedData) {
self.receivedData = nil;
}
self.receivedData = [[NSMutableData alloc] init];
}
- (void)connection:(NSURLConnection *)connection didReceiveData:(NSData *)data
{
[self.receivedData appendData:data];
}
- (void)connectionDidFinishLoading:(NSURLConnection *)connection
{
NSLog(@"finish requesting: %@", [[NSString alloc] initWithData:self.receivedData encoding:NSUTF8StringEncoding]);
self.urlConnection = nil;
}
- (void)connection:(NSURLConnection *)connection didFailWithError:(NSError *)error
{
NSLog(@"requesting error: %@", [error localizedDescription]);
self.urlConnection = nil;
}
@end
And the server side, php:
<?php
$uploaddir = './uploads/';
if(!file_exists($uploaddir)) @mkdir($uploaddir);
$file = basename($_FILES['file']['name']);
$uploadfilename = rand() . '-' . $file;
$uploadfile = $uploaddir . $uploadfilename;
if (move_uploaded_file($_FILES['file']['tmp_name'], $uploadfile)) {
$fileURL = "http://192.168.0.170/test/upload/uploads/{$uploadfilename}";
// echo '<a href=' . $fileURL . '>' . $fileURL . '</a>';
$jsonArray = array(
'status' => 1,
'url' => $fileURL,
);
echo json_encode($jsonArray);
} else {
echo json_encode( array( 'status' => -1 ) );
}
