ueditor上传图片后台处理方法-总结
分两种情况:
1.将图片放在本地
2.将图片放在OSS上
ueditor后台 请求参数格式 与 返回参数格式 的规范
1.config配置文件的请求与返回格式:
1. config 请求参数: GET {"action": "config"} POST "upfile": File Data 返回格式: // 需要支持callback参数,返回jsonp格式 { "imageUrl": "http://localhost/ueditor/php/controller.php?action=uploadimage", "imagePath": "/ueditor/php/", "imageFieldName": "upfile", "imageMaxSize": 2048, "imageAllowFiles": [".png", ".jpg", ".jpeg", ".gif", ".bmp"] }
这一个请求是读取配置文件config.json
请求形式为: /xxx?action=config
返回形式为: 配置文件config.json里面的内容,将注释替换掉直接输出json字符串即可
2.上传文件的请求与返回格式:
2. uploadimage 请求参数: GET {"action": "uploadimage"} POST "upfile": File Data 返回格式: { "state": "SUCCESS", "url": "upload/demo.jpg", "title": "demo.jpg", "original": "demo.jpg" } 3. uploadscrawl 请求参数: GET {"action": "uploadscrawl"} POST "content": Base64 Data 返回格式: { "state": "SUCCESS", "url": "upload/demo.jpg", "title": "demo.jpg", "original": "demo.jpg" } 4. uploadvideo 请求参数: GET {"action": "uploadvideo"} POST "upfile": File Data 返回格式: { "state": "SUCCESS", "url": "upload/demo.mp4", "title": "demo.mp4", "original": "demo.mp4" } 5. uploadfile 请求参数: GET {"action": "uploadfile"} POST "upfile": File Data 返回格式: { "state": "SUCCESS", "url": "upload/demo.zip", "title": "demo.zip", "original": "demo.zip" }
上面几个都是上传文件处理,所以返回格式都是一样的
请求形式为: /xxx?action=uploadimage
upfile为上传文件的表单名称
返回形式如下:
return json_encode( array( "state" => "", //上传状态,上传成功时必须返回"SUCCESS" "url" => "", //返回的地址 "title" => "", //新文件名 "original" => "", //原始文件名 "type" => "", //文件类型 "size" => "", //文件大小 ) );
3.列出文件列表的请求与返回格式:
6. listimage 请求参数: GET {"action": "listimage", "start": 0, "size": 20} 返回格式: // 需要支持callback参数,返回jsonp格式 { "state": "SUCCESS", "list": [{ "url": "upload/1.jpg" }, { "url": "upload/2.jpg" }, ], "start": 20, "total": 100 }
列出上传文件的列表
请求形式为: /xxx?action=listimage
upfile为上传文件的表单名称
返回的形式为:
json_encode( array( "state" => "SUCCESS", // 成功返回信息 "start" => $start, // 开始位置 "total" => count($files), // 文件个数统计 // 当前列出的文件列表 "list" => array( array('url' => '图片地址','mtime' => '时间戳'), array('url' => '图片地址','mtime' => '时间戳'), ) ) );
4.抓取远程图片的请求与返回格式:
7. catchimage 请求参数: GET { "action": "catchimage", "source": [ "http://a.com/1.jpg", "http://a.com/2.jpg" ] } 返回格式: // 需要支持callback参数,返回jsonp格式 // list项的state属性和最外面的state格式一致 { "state": "SUCCESS", "list": [{ "url": "upload/1.jpg", "source": "http://b.com/2.jpg", "state": "SUCCESS" }, { "url": "upload/2.jpg", "source": "http://b.com/2.jpg", "state": "SUCCESS" }, ] }
抓取远程文件功能默认是开启的,可以在配置文件中关闭,将catchRemoteImageEnable这一项的值设置为false即可。
请求的形式为: /xxx?action=catchimage
返回的形式为:
json_encode( array( 'state' => count($list) ? 'SUCCESS':'ERROR', 'list' => array( array( "state" => $info["state"], "url" => $info["url"], "size" => $info["size"], "title" => htmlspecialchars($info["title"]), "original" => htmlspecialchars($info["original"]), "source" => htmlspecialchars($imgUrl) ), array( "state" => $info["state"], "url" => $info["url"], "size" => $info["size"], "title" => htmlspecialchars($info["title"]), "original" => htmlspecialchars($info["original"]), "source" => htmlspecialchars($imgUrl) ) ) ) );

一、下面总结将文件上传到本地的方法:
下面这个方法是主调用方法,这个方法处理所有ueditor的请求。此方法调用到了很多函数,下面有列出。
/** * ueditor后端统一处理方法,上传文件、读取配置、文件列表等, * 如果多处调用,下面这个方法可以拆分出一个函数 * ueditor前端配置项 serverUrl:'调用此方法', * @param */ public function UploadSomething(){ header("Content-Type: text/html; charset=utf-8"); error_reporting(E_ERROR); // 登录检测 if($this->uid == 0){ if($_GET['action'] == 'config'){ echo preg_replace("/\/\*[\s\S]+?\*\//", "", file_get_contents("./Public/js/php/config.json")); }else{ echo json_encode(array('state'=> '请登录!')); } exit; } $CONFIG = json_decode(preg_replace("/\/\*[\s\S]+?\*\//", "", file_get_contents("./Public/js/php/config.json")), true); $action = $_GET['action']; switch ($action){ case 'config': $result = json_encode($CONFIG); break; case 'uploadimage': case 'uploadscrawl': case 'uploadvideo': case 'uploadfile': $result = Upload($CONFIG,$this->uid); // 图像缩放裁剪处理 if($_GET['action'] == 'uploadimage' or $_GET['action'] == 'uploadscrawl'){ $result = imageEdit($result); } break; case 'listimage': $result = Lists($CONFIG,$this->uid); break; case 'listfile': $result = Lists($CONFIG,$this->uid); break; case 'catchimage': $result = Crawler($CONFIG,$this->uid); if($_GET['action'] == 'catchimage'){ $result = imageEdit($result,true); } break; default: $result = json_encode(array( 'state'=> '请求地址出错' )); break; } if(isset($_GET["callback"])){ if(preg_match("/^[\w_]+$/", $_GET["callback"])){ echo htmlspecialchars($_GET["callback"]) . '(' . $result . ')'; }else{ echo json_encode(array('state'=> 'callback参数不合法')); } }else{ echo $result; } }
上传文件处理方法:
包括:'uploadimage','uploadscrawl','uploadvideo','uploadfile'共四个请求
/** * ueditor上传文件处理方法 * @param json $CONFIG 配置文件 * @param int $uid [可选]用户id,也可以是其他唯一的id,用于区别图片保存路劲, * 必须在配置文件中的保存路劲配置项添加{uid}才可起作用。 */ function Upload($CONFIG,$uid){ Vendor('Uploader','','.class.php'); $base64 = "upload"; switch (htmlspecialchars($_GET['action'])) { case 'uploadimage': $config = array( "pathFormat" => $CONFIG['imagePathFormat'], "maxSize" => $CONFIG['imageMaxSize'], "allowFiles" => $CONFIG['imageAllowFiles'] ); $fieldName = $CONFIG['imageFieldName']; break; case 'uploadscrawl': $config = array( "pathFormat" => $CONFIG['scrawlPathFormat'], "maxSize" => $CONFIG['scrawlMaxSize'], "allowFiles" => $CONFIG['scrawlAllowFiles'], "oriName" => "scrawl.png" ); $fieldName = $CONFIG['scrawlFieldName']; $base64 = "base64"; break; case 'uploadvideo': $config = array( "pathFormat" => $CONFIG['videoPathFormat'], "maxSize" => $CONFIG['videoMaxSize'], "allowFiles" => $CONFIG['videoAllowFiles'] ); $fieldName = $CONFIG['videoFieldName']; break; case 'uploadfile': default: $config = array( "pathFormat" => $CONFIG['filePathFormat'], "maxSize" => $CONFIG['fileMaxSize'], "allowFiles" => $CONFIG['fileAllowFiles'] ); $fieldName = $CONFIG['fileFieldName']; break; } $up = new \Uploader($fieldName, $config, $base64,$uid); return json_encode($up->getFileInfo()); }
列出文件列表:
包括 'listimage''listfile'共两个请求
/** * ueditor上传文件处理方法 * @param json $CONFIG 配置文件 * @param int $uid 此uid用来为区别显示不同用户的不同文件夹,如果其他方法用到了uid, * 那么此uid为必选,在ueditor的配置文件中要配置imageManagerListPath * 这项,例:"imageManagerListPath": "/Upload/forums/UserUpload/image/{uid}/", */ function Lists($CONFIG,$uid){ switch ($_GET['action']){ case 'listfile': $allowFiles = $CONFIG['fileManagerAllowFiles']; $listSize = $CONFIG['fileManagerListSize']; $path = $CONFIG['fileManagerListPath']; break; case 'listimage': default: $allowFiles = $CONFIG['imageManagerAllowFiles']; $listSize = $CONFIG['imageManagerListSize']; $path = $CONFIG['imageManagerListPath']; } $allowFiles = substr(str_replace(".", "|", join("", $allowFiles)), 1); $size = isset($_GET['size']) ? htmlspecialchars($_GET['size']) : $listSize; $start = isset($_GET['start']) ? htmlspecialchars($_GET['start']) : 0; $end = $start + $size; $path = $_SERVER['DOCUMENT_ROOT'] . (substr($path, 0, 1) == "/" ? "":"/") . $path; // 用$uid替换{uid},用来显示指定文件夹下目录列表 $path = str_replace("{uid}", $uid, $path); $files = getfiles($path, $allowFiles); if (!count($files)){ return json_encode(array( "state" => "no match file", "list" => array(), "start" => $start, "total" => count($files) )); } $len = count($files); for ($i = min($end, $len) - 1, $list = array(); $i < $len && $i >= 0 && $i >= $start; $i--){ $list[] = $files[$i]; } $result = json_encode(array( "state" => "SUCCESS", "list" => $list, "start" => $start, "total" => count($files) )); return $result; }
抓取远程文件:
包括 'catchimage'共一个请求
/** * 抓取远程图片处理方法 * @param json $CONFIG 配置文件 * @param int $uid [可选]用户id,也可以是其他唯一的id,用于区别图片保存路劲, * 必须在配置文件中的保存路劲配置项添加{uid}才可起作用。 */ function Crawler($CONFIG,$uid){ set_time_limit(0); Vendor('Uploader','','.class.php'); $config = array( "pathFormat" => $CONFIG['catcherPathFormat'], "maxSize" => $CONFIG['catcherMaxSize'], "allowFiles" => $CONFIG['catcherAllowFiles'], "oriName" => "remote.png" ); $fieldName = $CONFIG['catcherFieldName']; $list = array(); if (isset($_POST[$fieldName])) { $source = $_POST[$fieldName]; } else { $source = $_GET[$fieldName]; } foreach ($source as $imgUrl) { $item = new \Uploader($imgUrl, $config, "remote",$uid); $info = $item->getFileInfo(); array_push($list, array( "state" => $info["state"], "url" => $info["url"], "size" => $info["size"], "title" => htmlspecialchars($info["title"]), "original" => htmlspecialchars($info["original"]), "source" => htmlspecialchars($imgUrl) )); } return json_encode(array( 'state'=> count($list) ? 'SUCCESS':'ERROR', 'list'=> $list )); }
使用到的上传类:

遍历目录下指定文件:
/** * 遍历获取目录下的指定类型的文件,并返回所有目录下文件的列表数组 * * @param string $path 文件路劲 * @param array $allowFiles 要列出列表的文件类型 * @param array $files [可选]要返回的数组,地址引用 * @return array array( array('url' => '图片地址','mtime' => '时间戳'), array('url' => '图片地址','mtime' => '时间戳'), ); */ function getfiles($path, $allowFiles, &$files = array()){ if (!is_dir($path)) return null; if(substr($path, strlen($path) - 1) != '/') $path .= '/'; $handle = opendir($path); while (false !== ($file = readdir($handle))) { if ($file != '.' && $file != '..') { $path2 = $path . $file; if (is_dir($path2)) { getfiles($path2, $allowFiles, $files); } else { if (preg_match("/\.(".$allowFiles.")$/i", $file)) { $files[] = array( 'url' => substr($path2, strlen($_SERVER['DOCUMENT_ROOT'])), 'mtime' => filemtime($path2) ); } } } } return $files; }
图片上传后的处理方法:
/** * 上传图片的各种处理 * @param json $result */ function imageEdit($result,$isCatch){ $result = json_decode($result,JSON_UNESCAPED_UNICODE); // 图片保存的地址,非此地址不操作 $str = 'Upload/forums/UserUpload/image'; if($isCatch){ for ($i = 0; $i < count($result['list']); $i++){ if($result['list'][$i]['state'] == 'SUCCESS'){ $imgUrl = $result['list'][$i]['url']; if(substr_count($imgUrl,$str)){ $imgUrl = './'.strstr($imgUrl,$str); zoom_image($imgUrl,400,null,1); } } } }else{ if($result['state'] == 'SUCCESS'){ $imgUrl = $result['url']; if(substr_count($imgUrl,$str)){ $imgUrl = './'.strstr($imgUrl,$str); zoom_image($imgUrl,400,null,1); } } } return json_encode($result,JSON_UNESCAPED_UNICODE); }
图片缩放加水印:
/** * 图像的裁剪、缩放、加水印 * @param string $path 路径 * @param int $width 裁剪的宽度/限制的高度或宽度,当有$height值时此值为图片的宽度,否则为限制的宽度或高度 * @param int $height [可选]裁剪的高度 * @param boolean $water [可选]是否加水印 * @param int $word [可选]水印文字 */ function zoom_image($path,$width = 300,$height = null,$water = null,$word = 'http://www.ainishe.com'){ $image = new \Think\Image(); $image->open($path); $imgWidth = $image->width(); $imgHeight = $image->height(); // 限制尺寸 if($width and !$height){ $maxSize = $width; // 宽度或高度大于规定尺寸时 if($imgWidth > $maxSize or $imgHeight > $maxSize){ $size = image_min_width($imgWidth,$imgHeight,$maxSize); $image->thumb($size['width'], $size['height']); $do = true; $dowater = true; } // 裁剪固定尺寸 }else if($width and $height){ $size = image_min_width($imgWidth,$imgHeight,$width); $image->thumb($size['width'], $size['height'])->crop($width, $height); $do = true; $dowater = true; } if($dowater and $water and $word){ $image->text($word,'./Public/images/arial.ttf',20,'#dddddd', \Think\Image::IMAGE_WATER_SOUTHEAST,-10); } // 未操作则不保存 if($do){ $image->save($path); } }
二、将文件上传到OSS
未完待续。。。
将Uploader.class.php文件中的移动文件步骤改为上传到OSS即可。
