我是PHP和Objective-C的新手,我已經搜索了這個答案,但一切看起來很複雜,我無法理解。我正嘗試使用PHP將圖像文件上傳到我的ftp服務器。PHP - 未能打開流:沒有這樣的文件或目錄
我用這個代碼在我的應用程序的圖片上傳:
UIImage *myImage = [UIImage imageNamed:@"black_strip.png"];
NSData *imageData = UIImagePNGRepresentation(myImage);
// setting up the URL to post to
NSString *urlString = @"http://www.myurl.net/GagVidApp/uploadProfImage.php";
// setting up the request object now
NSMutableURLRequest *request = [[NSMutableURLRequest alloc] init];
[request setURL:[NSURL URLWithString:urlString]];
[request setHTTPMethod:@"POST"];
NSString *boundary = @"---------------------------14737809831466499882746641449";
NSString *contentType = [NSString stringWithFormat:@"multipart/form-data; boundary=%@",boundary];
[request addValue:contentType forHTTPHeaderField: @"Content-Type"];
/*
now lets create the body of the post
*/
NSMutableData *body = [NSMutableData data];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Disposition: form-data; name=\"userfile\"; filename=\"ipodfile.png\"\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[@"Content-Type: application/octet-stream\r\n\r\n" dataUsingEncoding:NSUTF8StringEncoding]];
[body appendData:[NSData dataWithData:imageData]];
[body appendData:[[NSString stringWithFormat:@"\r\n--%@--\r\n",boundary] dataUsingEncoding:NSUTF8StringEncoding]];
// setting the body of the post to the reqeust
[request setHTTPBody:body];
// now lets make the connection to the web
NSData *returnData = [NSURLConnection sendSynchronousRequest:request returningResponse:nil error:nil];
NSString *returnString = [[NSString alloc] initWithData:returnData encoding:NSUTF8StringEncoding];
NSLog(@"returnString: %@", returnString);
這裏是我的PHP代碼:
<?php
$file = basename($_FILES['userfile']['name']);
$remote_file = basename($_FILES['userfile']['name']);
//$remote_file = 'readme.txt';
// set up basic connection
$ftp_server = "www.myurl.net";
$ftp_user_name = "myusername";
$ftp_user_pass = "mypassword";
$conn_id = ftp_connect($ftp_server);
// login with username and password
$login_result = ftp_login($conn_id, $ftp_user_name, $ftp_user_pass);
// check connection
if ((!$conn_id) || (!$login_result)) {
echo "FTP connection has failed!";
echo "Attempted to connect to $ftp_server for user $ftp_user_name";
exit;
} else {
echo "Connected to $ftp_server, for user $ftp_user_name";
}
// upload a file
if (ftp_put($conn_id, $remote_file, $file, FTP_ASCII)) {
echo "successfully uploaded $file\n";
} else {
echo "There was a problem while uploading $file\n";
}
// close the connection
ftp_close($conn_id);
?>
返回字符串我在我的應用程序得到的是:
returnString: Connected to www.myurl.net, for user myuser<br />
<b>Warning</b>: ftp_put(ipodfile.png) [<a href='function.ftp-put'>function.ftp-put</a>]: **failed to open stream: No such file or directory in** <b>/home/load2unet/domains/myurl.net/public_html/GagVidApp/uploadProfImage.php</b> on line <b>24</b><br />
There was a problem while uploading ipodfile.png
我一直在試圖找到答案,但沒有得到任何運氣。任何幫助將非常感謝!謝謝
我該怎麼做?你能給我一些示例代碼嗎? – tnylee
還沒有嘗試過,但最有可能''ftp_put($ connid,$ remote_file,$ _FILES ['userfile'] ['tmp_name'],FTP_ASCII)''會起作用。 –
