百度的Ueditor上传到七牛，oss等第三方存储的通用方法（php版）

用百度的Ueditor上传图片默认保存到本地，在分布式系统中使用非常不方便，一般需要上传到七牛，阿里云的oss上

需要七牛sdk 6.1.9（支持php5.2，高版本可自行改正）

Ueditor 1.4.3

主要原理：百度ueditor上传文件时会创建本地文件，并返回文件路径 $this->fullName，我们需要修改上传类，在上传成功时进行文件的转存，转存成功后把本地的文件删除，该方法可以处理图片，附件等小文件，大文件不建议在ueditor上上传。

提供修改方式：（oss只要修改配置文件和上传方法就行^_^）

1.七牛官网下载sdk6.1.9，放在php的文件夹下

2.在ueditor/php下qiniu_config.php

<?php
    return array(
        "bucket"=>"***",
        "accessKey"=>"****",
        "secretKey"=>"****"
    );
?>

3.修改php下的config.json，把图片访问的前缀改成相应的远程访问的前缀

"imageUrlPrefix": "", /* 图片访问路径前缀 */

4.修改主要的上传文件Uploader.class.php,将upFile方法改成如下方法

/**
 * 上传到七牛
 * @return mixed
 */
private function upFile()
{
    $file = $this->file = $_FILES[$this->fileField];
    if (!$file) {
        $this->stateInfo = $this->getStateInfo("ERROR_FILE_NOT_FOUND");
        return;
    }
    if ($this->file['error']) {
        $this->stateInfo = $this->getStateInfo($file['error']);
        return;
    } else if (!file_exists($file['tmp_name'])) {
        $this->stateInfo = $this->getStateInfo("ERROR_TMP_FILE_NOT_FOUND");
        return;
    } else if (!is_uploaded_file($file['tmp_name'])) {
        $this->stateInfo = $this->getStateInfo("ERROR_TMPFILE");
        return;
    }

    $this->oriName = $file['name'];
    $this->fileSize = $file['size'];
    $this->fileType = $this->getFileExt();
    $this->fullName = $this->getFullName();
    $this->filePath = $this->getFilePath();
    $this->fileName = $this->getFileName();
    $dirname = dirname($this->filePath);

    //检查文件大小是否超出限制
    if (!$this->checkSize()) {
        $this->stateInfo = $this->getStateInfo("ERROR_SIZE_EXCEED");
        return;
    }

    //检查是否不允许的文件格式
    if (!$this->checkType()) {
        $this->stateInfo = $this->getStateInfo("ERROR_TYPE_NOT_ALLOWED");
        return;
    }

    //创建目录失败
    if (!file_exists($dirname) && !mkdir($dirname, 0777, true)) {
        $this->stateInfo = $this->getStateInfo("ERROR_CREATE_DIR");
        return;
    } else if (!is_writeable($dirname)) {
        $this->stateInfo = $this->getStateInfo("ERROR_DIR_NOT_WRITEABLE");
        return;
    }

    //移动文件
    if (!(move_uploaded_file($file["tmp_name"], $this->filePath) && file_exists($this->filePath))) { //移动失败
        $this->stateInfo = $this->getStateInfo("ERROR_FILE_MOVE");
    } else { //移动成功

        //执行到这里，代表已经完成了上传，此时系统会提示上传成功
        //------------------------------------------------  start  ---------------------------------------------------------
        //上传到七牛
        require_once("qiniu/io.php");
        require_once("qiniu/rs.php");
        $config = require_once("qiniu_config.php");
        $bucket = $config['bucket']; //仓库名
        //截取原始文件后缀名
        //$key1 = "Uploads/".time().mt_rand(10,99).$this->getFileExt();
        $accessKey = $config['accessKey'];
        $secretKey = $config['secretKey'];

        Qiniu_SetKeys($accessKey, $secretKey);
        $putPolicy = new Qiniu_RS_PutPolicy($bucket);
        $upToken = $putPolicy->Token(null);
        $putExtra = new Qiniu_PutExtra();
        $putExtra->Crc32 = 1;
        //$file[ "tmp_name" ] ueditor上传的临时文件路径
        list($ret, $err) = Qiniu_PutFile($upToken,$this->fullName,$_SERVER['DOCUMENT_ROOT']."/".$this->fullName, $putExtra);
        //成功了，删除本地文件
        if($ret)
        {
            @unlink($_SERVER['DOCUMENT_ROOT']."/".$this->fullName);
            //file_put_contents("./log/log.txt","
time:".time()."  ".json_encode($ret)."
",FILE_APPEND);
        }
        if($err)
        {
            if(!is_dir("./log")){
                if(!mkdir("log",0755,true)){
                    die("当前目录没有写权限");
                }
            }
            file_put_contents("./log/log.txt","
time:".time()."  ".json_encode($_SERVER['DOCUMENT_ROOT']."/".$this->fullName)."
",FILE_APPEND);
            $this->stateInfo = $this->getStateInfo("QINIU_ERR");
        }else{
            $this->stateInfo = $this->stateMap[0];
        }
        //------------------------------------------------- end   ---------------------------------------------------------
    }
}

5.修改upBase64方法（如果不用截屏和涂鸦可以不改）

/**
 * 处理base64编码的图片上传
 * @return mixed
 */
private function upBase64()
{
    $base64Data = $_POST[$this->fileField];
    $img = base64_decode($base64Data);

    $this->oriName = $this->config['oriName'];
    $this->fileSize = strlen($img);
    $this->fileType = $this->getFileExt();
    $this->fullName = $this->getFullName();
    $this->filePath = $this->getFilePath();
    $this->fileName = $this->getFileName();
    $dirname = dirname($this->filePath);

    //检查文件大小是否超出限制
    if (!$this->checkSize()) {
        $this->stateInfo = $this->getStateInfo("ERROR_SIZE_EXCEED");
        return;
    }

    //创建目录失败
    if (!file_exists($dirname) && !mkdir($dirname, 0777, true)) {
        $this->stateInfo = $this->getStateInfo("ERROR_CREATE_DIR");
        return;
    } else if (!is_writeable($dirname)) {
        $this->stateInfo = $this->getStateInfo("ERROR_DIR_NOT_WRITEABLE");
        return;
    }

    //移动文件
    if (!(file_put_contents($this->filePath, $img) && file_exists($this->filePath))) { //移动失败
        $this->stateInfo = $this->getStateInfo("ERROR_WRITE_CONTENT");
    } else { //移动成功

        require_once("qiniu/io.php");
        require_once("qiniu/rs.php");

        $config = require_once("qiniu_config.php");
        $bucket = $config['bucket']; //仓库名
        //截取原始文件后缀名
        //$key1 = "Uploads/".time().mt_rand(10,99).$this->getFileExt();
        $accessKey = $config['accessKey'];
        $secretKey = $config['secretKey'];

        Qiniu_SetKeys($accessKey, $secretKey);
        $putPolicy = new Qiniu_RS_PutPolicy($bucket);
        $upToken = $putPolicy->Token(null);
        $putExtra = new Qiniu_PutExtra();
        $putExtra->Crc32 = 1;
        //$file[ "tmp_name" ] ueditor上传的临时文件路径
        list($ret, $err) = Qiniu_PutFile($upToken,$this->fullName,$_SERVER['DOCUMENT_ROOT']."/".$this->fullName, $putExtra);
        if($ret)
        {
            //删临时文件
            @unlink($_SERVER['DOCUMENT_ROOT']."/".$this->fullName);
          //  file_put_contents("./log/log.txt","
time:".time()."  ".json_encode($ret)."
",FILE_APPEND);
        }

        if($err)
        {
            file_put_contents("./log/log.txt","
time:".time()."  ERR:".json_encode($err)."    ".json_encode($_SERVER['DOCUMENT_ROOT']."/".$this->fullName)."
",FILE_APPEND);
           // $this->stateInfo = $this->getStateInfo("QINIU_ERR");
        }

        $this->stateInfo = $this->stateMap[0];
    }

}

6.修改重命名方法，主要是随机数那里抹去两个零就可以了

/**
     * 重命名文件
     * @return string
     */
    private function getFullName()
    {
        //替换日期事件
        $t = time();
        $d = explode('-', date("Y-y-m-d-H-i-s"));
        $format = $this->config["pathFormat"];
        $format = str_replace("{yyyy}", $d[0], $format);
        $format = str_replace("{yy}", $d[1], $format);
        $format = str_replace("{mm}", $d[2], $format);
        $format = str_replace("{dd}", $d[3], $format);
        $format = str_replace("{hh}", $d[4], $format);
        $format = str_replace("{ii}", $d[5], $format);
        $format = str_replace("{ss}", $d[6], $format);
        $format = str_replace("{time}", $t, $format);

        //过滤文件名的非法自负,并替换文件名
        $oriName = substr($this->oriName, 0, strrpos($this->oriName, '.'));
        $oriName = preg_replace("/[|?"<>/*\\]+/", '', $oriName);
        $format = str_replace("{filename}", $oriName, $format);

        //替换随机字符串
        $randNum = rand(1, 100000000) . rand(1, 100000000);
        if (preg_match("/{rand:([d]*)}/i", $format, $matches)) {
            $format = preg_replace("/{rand:[d]*}/i", substr($randNum, 0, $matches[1]), $format);
        }

        $ext = $this->getFileExt();
        return $format . $ext;
    }
