POST SQLITE文件到远程服务器
我真的很累，在这里和谷歌search，但结果不好。
我问如果我想上传文件/本地SQLITE文件到我的服务器
我怎么能做到这一点，从iOS做一些备份数据库
您的答复将不胜感激。
对于HTTP正文中的文件，使用header的Content-Type和Content-Type: application/octet-stream multipart/form-data 。
好吧，我将演示一个演示，只需创build一个新的Xcode项目模板“空应用程序”，检查“使用ARC”，然后粘贴：
#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:@"--%@\r\n", boundary] dataUsingEncoding:NSUTF8StringEncoding]]; [postData appendData:[[NSString stringWithFormat:@"Content-Disposition:form-data; name=\"file\"; filename=\"test.sqlite\"\r\n"] dataUsingEncoding:NSUTF8StringEncoding]]; [postData appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]]; [postData appendData:fileData]; [postData appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n", 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
和服务器端，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 ) ); }
