php 百度Ueditor 上传图片到阿里云oss

  • A+
所属分类:php

百度Ueditor 默认是将图片上传到服务器本地。项目需要将图片上传到阿里云oss
一.下载oss 的sdk
https://help.aliyun.com/document_detail/85580.html
二.修改源码
1.修改/ueditor/php/Uploader.class.php 的upFile()方法。
在最后一个else,里面将文件上传到oss。

//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
            $file = $_SERVER['DOCUMENT_ROOT']."/".$this->fullName;//文件路径,必须是本地的。
            $remoteurl = $this->upload($file);
            $GLOBALS['ossimgurl'] = $remoteurl;
            // 删除本地文件
            unlink($file);
            $this->stateInfo = $this->stateMap[0];
        }

2.修改getFileInfo() 方法,将url ,返回值修改为$GLOBALS['ossimgurl']

    public function getFileInfo()
    {
        return array(
            "state" => $this->stateInfo,
            //"url" => $this->fullName,
            "url" => $GLOBALS['ossimgurl'],
            "title" => $this->fileName,
            "original" => $this->oriName,
            "type" => $this->fileType,
            "size" => $this->fileSize
        );
    }

            "type" => $this->fileType,
            "size" => $this->fileSize
        );
    }

}

注意:此方法,从本地上传一张,多张图片都没有问题,但是粘贴操作会导致原来的图片不显示,

参考我的另一篇博客解决。
