fastDFS中使用php上傳檔案 -- http上傳與下載圖片
阿新 • • 發佈:2019-02-13
CleverCode研究完fastDFS後,嘗試著使用php上傳檔案到fastdfs。
1 fastDFS安裝
fastdfs分散式架構配置參考:http://blog.csdn.net/clevercode/article/details/52267080。
fastdfs使用nginx配置參考:http://blog.csdn.net/clevercode/article/details/52276169。
fastdfs縮圖生成參考:http://blog.csdn.net/clevercode/article/details/52278482。
2 fastDFS中php擴充套件的安裝
2.1 安裝
# cd /usr/local/src/fastdfs/FastDFS/php_client # /usr/local/php5/bin/phpize # ./configure --with-php-config=/usr/local/php5/bin/php-config # make && make install # cat fastdfs_client.ini >> /usr/local/php5/etc/php.ini
2.2 檢視是否安裝成功
# php -m | grep fastdfs_client
2.3 配置fastDFS的client.conf
# vi /etc/fdfs/client.conf
tracker_server=192.168.101.135:22122
http.tracker_server_port=80
2.4重啟pkill php-fpm
# pkill php-fpm
# /usr/local/php5/sbin/php-fpm
3 通過http上傳
3.1 上傳頁面程式碼
test.php
<html> <body> <form action="upload.php" method="post" enctype="multipart/form-data"> <label for="file">Filename:</label> <input type="file" name="upFile" id="upFile" /> <br /> <input type="submit" name="submit" value="Submit" /> </form> </body> </html>
3.2 接收檔案php
upload.php
<?php //上傳附件 function uploadAttach() {/*{{{*/ $ret = array(); $ret['errorcode'] = 0; $ret['errormsg'] = ''; if(!$_FILES || false == isset($_FILES["upFile"])) { $ret['errorcode'] = 1; $ret['errormsg'] = "ERROR:upFile is not set"; return $ret; } $file = $_FILES["upFile"]; if (false == isset($file['tmp_name']) || false == is_file($file['tmp_name'])) { $ret['errorcode'] = 2; $ret['errormsg'] = "tmp_name is not file"; return $ret; } if (0 == filesize($file['tmp_name'])) { $ret['errorcode'] = 3; $ret['errormsg'] = "tmp_name filesize is 0"; return $ret; } $curlFile = new CurlFile($file['tmp_name'], $file['type'], $file['name']); $fileSuffix = getSuffix($curlFile->getPostFilename()); $ret['file'] = $file; $ret['fileId'] = uploadToFastdfs($curlFile, $fileSuffix); return $ret; }/*}}}*/ //獲取字尾 function getSuffix($fileName) {/*{{{*/ preg_match('/\.(\w+)?$/', $fileName, $matchs); return isset($matchs[1])?$matchs[1]:''; }/*}}}*/ //上傳檔案到fastdfs function uploadToFastdfs(CurlFile $file, $fileSuffix) {/*{{{*/ $fdfs = new FastDFS(); $tracker = $fdfs->tracker_get_connection(); $fileId = $fdfs->storage_upload_by_filebuff1(file_get_contents($file->getFilename()), $fileSuffix); $fdfs->tracker_close_all_connections(); return $fileId; }/*}}}*/ function start() { $ret = uploadAttach(); print_r($ret); } start(); ?>
3.3 上傳一張圖片
3.4 上傳結果
3.5 訪問(下載) http://192.168.101.132/group1/M00/00/00/wKhlhVfBiu2AWrzoAAKp3t_hiGI748.png
4 curl上傳
3 的http上傳方式,需要在每一臺php伺服器上都按裝fastdfs的php擴充套件。這裡通過curl方式,直接上傳到具有fastdfs擴充套件的php伺服器上。
curlupload.php
<?php
function curl_multipart_post($url, $post_data = array(), $file_fields = array(), $timeout=30)
{/*{{{*/
$result = array('errno' => 0, 'errmsg' => '', 'result' => '');
$ch = curl_init();
//set various curl options first
// set url to post to
curl_setopt($ch, CURLOPT_URL, $url);
// return into a variable rather than displaying it
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
//set curl function timeout to $timeout
curl_setopt($ch, CURLOPT_TIMEOUT, $timeout);
curl_setopt($ch, CURLOPT_VERBOSE, false);
//set method to post
curl_setopt($ch, CURLOPT_POST, true);
// disable Expect header
// hack to make it working
$headers = array("Expect: ");
curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
// initialize result post array
$result_post = array();
//generate post string
$post_array = array();
$post_strings = array();
if (!is_array($post_data)) {
$result['errno'] = 5;
$result['errmsg'] = 'Params error.';
return json_encode($result);
// return false;
}
foreach($post_data as $key=>$value) {
$post_array[$key] = $value;
$post_strings[] = urlencode($key)."=".urlencode($value);
}
$post_string = implode("&", $post_strings);
// set post string
// curl_setopt($ch, CURLOPT_POSTFIELDS, $post_string);
// set multipart form data - file array field-value pairs
if (!empty($file_fields)) {
foreach($file_fields as $key => $value) {
if (strpos(PHP_OS, "WIN") !== false) {
$value = str_replace("/", "\\", $value); // win hack
}
$file_fields[$key] = "@".$value;
}
}
// set post data
$result_post = array_merge($post_array, $file_fields);
curl_setopt($ch, CURLOPT_POSTFIELDS, $result_post);
// print_r($result_post);
//and finally send curl request
$output = curl_exec($ch);
$result['result'] = $output;
// print_r($result);
if (curl_errno($ch )) {
$result['errno'] = curl_errno($ch);
$result['errmsg'] = curl_error($ch);
// return false;
} else {
// return $result;
}
curl_close($ch);
return $result;
}/*}}}*/
function start()
{
$url = 'http://192.168.101.132/upload.php';
$post = array('signature' => 123456);
$fileFields = array('upFile' => '/data0/webRoot/upload.php');
$ret = curl_multipart_post($url,$post,$fileFields);
print_r($ret);
}
start();
?>
