前后端分离 Ueditor + PHP 实现阿里云Oss上传

首先去百度下载Ueditor PHP(一般都是UTF-8版本)的

当然首先要 composer这样滴: 

"require": {
   "aliyuncs/oss-sdk-php": "~2.0.0",
},

解压后结构如下：

第一步： 创建OssInUe.php 结构如下  文件名称自定义这里以他为例:

第二步: 上菜：

";
        $object = $fullName;//" <您使用的Object名字，注意命名规范>";

        $content = $file["tmp_name"];//上传的文件
        try {
            $ossClient = new OssClient($accessKeyId, $accessKeySecret, $endpoint);
            $ossClient->setTimeout(3600 /* seconds */);
            $ossClient->setConnectTimeout(10 /* seconds */);
            //$ossClient->putObject($bucket, $object, $content);
            // 先把本地的example.jpg上传到指定$bucket, 命名为$object
            $ossClient->uploadFile($bucket, $object, $content);
            $signedUrl = $ossClient->signUrl($bucket, $object);
            $path = explode('?',$signedUrl)[0];
            $obj['status'] = true;
            $obj['path'] = $path;
        } catch (OssException $e) {
            $obj['status'] = false;
            $obj['path'] = "";
            print $e->getMessage();
        }
        return $obj;
    }
}

第三步: 修改 Uploader.class.php 直接复制一下代码(因为确实有人会抄错的):

 "临时文件错误",
        "ERROR_TMP_FILE_NOT_FOUND" => "找不到临时文件",
        "ERROR_SIZE_EXCEED" => "文件大小超出网站限制",
        "ERROR_TYPE_NOT_ALLOWED" => "文件类型不允许",
        "ERROR_CREATE_DIR" => "目录创建失败",
        "ERROR_DIR_NOT_WRITEABLE" => "目录没有写权限",
        "ERROR_FILE_MOVE" => "文件保存时出错",
        "ERROR_FILE_NOT_FOUND" => "找不到上传文件",
        "ERROR_WRITE_CONTENT" => "写入文件内容错误",
        "ERROR_UNKNOWN" => "未知错误",
        "ERROR_DEAD_LINK" => "链接不可用",
        "ERROR_HTTP_LINK" => "链接不是http链接",
        "ERROR_HTTP_CONTENTTYPE" => "链接contentType不正确"
    );

    /**

第四步: 记住这里啥都别动 

第五步: 打完收工!  我是前后端分离  把你的controller.php 路径给前端就OK了.
