layui OSS Web直传

此次封装的oss直传使用的是官网Browser.js和layui结合封装的插件。调用方式相对来说简单快捷

1、html是一个上传按钮。这里注意一下两个id，

　　id="upload-normal" ：上传按钮的id。

　　id="upload-normal-list"：上传完图片（文件）展示的地方

　　这两个是有规则的，必须为上传按钮的id 拼接上 -list

.close_btn{ position: absolute; top:-7px!important; right: -7px!important; background: rgba(0,0,0,0.5); border-radius: 50%; width: 15px; height: 15px; border-radius: 50%; line-height: 15px;}

 1     <div class="layui-form-item">
 2         <label class="layui-form-label">图片</label>
 3         <div class="layui-input-block">
 4             <div class="layui-upload">
 5                 <button type="button" class="layui-btn layui-btn-sm" id="upload-normal">上传图片</button>
 6                 <div class="layui-upload-list" id="upload-normal-list" style="display: flex; flex-wrap: wrap;">
 7                 </div>
 8             </div>
 9         </div>
10     </div>

2、js

首先去官网下载sdk并按照文档引入js

　官方链接：https://helpcdn.aliyun.com/document_detail/64041.html?spm=a2c4g.11186623.6.1218.4d8b23f2hNmYrh

　封装后的js（注意最好使用layui2.6.5及以上版本因为他这个版本修复了（这个版本之前的自己去修改下layui.js）

[修复] form 组件的 name="arr[]" 在元素动态插入后出现序号异常的问题

<script src="src/lib/extend/aliyun-oss-sdk.min.js"></script>

15 });

以上是前端上传的代码及调用方式。接下来稍微简单说一下后代返回的签名及上传回调

你可以使用官网php的sdk，也可以用composer安装

　我使用的是composer

composer require aliyunsts/aliyun-sts

1、获取签名代码：

    public function sts()
    {
        $config = config("aliyun.oss_sts");
        $AccessKeyID = $config['AccessKeyID'];
        $AccessKeySecret = $config['AccessKeySecret'];
        $roleArn = $config['RoleArn'];
        $RoleSessionName = $config['RoleSessionName'];
        $tokenExpire = $config['DurationSeconds'];
        $policy = $this->_getPolicy();

        $iClientProfile = DefaultProfile::getProfile("cn-beijing", $AccessKeyID, $AccessKeySecret);
        $client = new DefaultAcsClient($iClientProfile);
        $request = new AssumeRoleRequest();
        $request->setRoleSessionName($RoleSessionName);
        $request->setRoleArn($roleArn);
        $request->setPolicy($policy);
        $request->setDurationSeconds($tokenExpire);
        $response = $client->doAction($request);

        $rows = array();
        $body = $response->getBody();
        $content = json_decode($body);
        $rows['status'] = $response->getStatus();
        if ($response->getStatus() == 200) {
            $rows['AccessKeyId'] = $content->Credentials->AccessKeyId;
            $rows['AccessKeySecret'] = $content->Credentials->AccessKeySecret;
            $rows['Expiration'] = $content->Credentials->Expiration;
            $rows['SecurityToken'] = $content->Credentials->SecurityToken;
            return $this->jsonSuccess($rows);
        }
        return $this->jsonError($content->Message);
    }

2、aliyun文件回调

public function callbackFile()
    {
        $is_success = false;
        try {
            // 1.获取OSS的签名header和公钥url header
            $authorizationBase64 = "";
            $pubKeyUrlBase64 = "";
            /*
             * 注意：如果要使用HTTP_AUTHORIZATION头，你需要先在apache或者nginx中设置rewrite，以apache为例，修改
             * 配置文件/etc/httpd/conf/httpd.conf(以你的apache安装路径为准)，在DirectoryIndex index.php这行下面增加以下两行
              RewriteEngine On
              RewriteRule .* - [env=HTTP_AUTHORIZATION:%{HTTP:Authorization},last]
             * */
            if (isset($_SERVER['HTTP_AUTHORIZATION'])) {
                $authorizationBase64 = $_SERVER['HTTP_AUTHORIZATION'];
            }
            if (isset($_SERVER['HTTP_X_OSS_PUB_KEY_URL'])) {
                $pubKeyUrlBase64 = $_SERVER['HTTP_X_OSS_PUB_KEY_URL'];
            }

            if ($authorizationBase64 == '' || $pubKeyUrlBase64 == '') {
                header("http/1.1 403 Forbidden");
                exit();
            }

            // 2.获取OSS的签名
            $authorization = base64_decode($authorizationBase64);

            // 3.获取公钥
            $pubKeyUrl = base64_decode($pubKeyUrlBase64);
            $ch = curl_init();
            curl_setopt($ch, CURLOPT_URL, $pubKeyUrl);
            curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
            curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);
            $pubKey = curl_exec($ch);
            if ($pubKey == "") {
                //header("http/1.1 403 Forbidden");
                exit();
            }

            // 4.获取回调body
            $body = file_get_contents('php://input');

            trace($body, __METHOD__);

            // 5.拼接待签名字符串
            $path = $_SERVER['REQUEST_URI'];
            $pos = strpos($path, '?');
            if ($pos === false) {
                $authStr = urldecode($path) . "\n" . $body;
            } else {
                $authStr = urldecode(substr($path, 0, $pos)) . substr($path, $pos, strlen($path) - $pos) . "\n" . $body;
            }

            // 6.验证签名
            $ok = openssl_verify($authStr, $authorization, $pubKey, OPENSSL_ALGO_MD5);
            if (empty($ok)) {
                throw new Exception('验证签名失败');
            }
　　　　　　　
　　　　　　　// 7.处理相关业务



$is_success = true;
        } catch (\Exception $e) {
            $body = file_get_contents('php://input');
            $res = 'oss callback error' . $e->getMessage() . $e->getLine();
            Log::record($res . ",data:" . json_encode($body), 'warning');
        }

        if ($is_success) {
            return $this->jsonSuccess($res);
        } else {
            return $this->jsonError($res);
        }
    }

sts策略

private function _getPolicy(){
    //你的sts策略
}

可能有有些还不够完善，有啥问题再继续更新修改吧！！！！！！
