ThinkPHP实现JavaScript上传大视频到七牛云实

1.通过Composer安装七牛云PHP SDK,官方文档https://developer.qiniu.com/kodo/sdk/1283/javascript
2.后端核心代码如下：

use Qiniu\Auth as Auth;
use Qiniu\Config;
use Qiniu\Storage\BucketManager;
use Qiniu\Storage\UploadManager;
......
......
//上传七牛云
    function qiniu_upload(){
        set_time_limit(120);
        ini_set('memory_limit','2000M');
        if(!empty($_FILES['file']))
        {
            $file = request()->file('file');
            // 要上传图片的本地路径
            $filePath = $file->getRealPath();
            $ext = pathinfo($file->getInfo('name'), PATHINFO_EXTENSION);  //后缀
            //获取当前控制器名称
            $controllerName = 'index';
            // 上传到七牛后保存的文件名
            $key =substr(md5($file->getRealPath()) , 0, 5). date('YmdHis') . rand(0, 9999) . '.' . $ext;
            // 需要填写你的 Access Key 和 Secret Key
            $accessKey = config('ACCESSKEY');
            $secretKey = config('SECRETKEY');
            // 构建鉴权对象
            $auth = new Auth($accessKey, $secretKey);
            // 要上传的空间
            $bucket = config('BUCKET');
            $domain = config('DOMAINImage');
            $token = $auth->uploadToken($bucket);
            // 初始化 UploadManager 对象并进行文件的上传
            $uploadMgr = new UploadManager();
            // 调用 UploadManager 的 putFile 方法进行文件的上传
            list($ret, $err) = $uploadMgr->putFile($token, $key, $filePath);
            if ($err !== null) {
                retErr($err);
            } else {
                //返回图片的完整URL
                $url = $domain.$ret['key'];
                echo $url;
            }
        }
    }

3.前端上传组件使用plupload，官方下载地址https://www.plupload.com/
4.选择一款想用的demo，核心代码如下：

......
......
<link rel="stylesheet" href="__PUBLIC__/plupload/js/jquery.plupload.queue/css/jquery.plupload.queue.css" type="text/css" media="screen" />
<script src="//ajax.googleapis.com/ajax/libs/jquery/1.9.0/jquery.min.js"></script>
<script type="text/javascript" src="__PUBLIC__/plupload/js/plupload.full.min.js"></script>
<script type="text/javascript" src="__PUBLIC__/plupload/js/jquery.plupload.queue/jquery.plupload.queue.js"></script>
......
......
<label class="col-sm-2 col-sm-2 control-label">上传七牛云</label>
        <div class="col-sm-10">
                <div id="uploader" >
                        <p>Your browser doesn't have Flash, Silverlight or HTML5 support.</p>
                </div>
        </div>
</div>
......
......
$(function() {

    // Setup html5 version
    $("#uploader").pluploadQueue({
        // General settings
        runtimes : 'html5,flash,silverlight,html4',
        url : '{:url("xxx/qiniu_upload")}',//对应后端方法
        chunk_size: '400mb',//分片上传
        rename : true,
        dragdrop: true,
        filters : {
            // Maximum file size
            max_file_size : '500mb',
            // Specify what files to browse for
            mime_types: [
                {title : "Image files", extensions : "jpg,gif,png,mp4"},
                {title : "Zip files", extensions : "zip"}
            ]
        },
        // Resize images on clientside if we can
        resize : {width : 320, height : 240, quality : 90},
        flash_swf_url : '__PUBLIC__/js/Moxie.swf',//引入js路径
        silverlight_xap_url : '__PUBLIC__/js/Moxie.xap',//引入js路径
        init: {
            FileUploaded:function(up,file,result){
                layer.msg('上传成功');
                                $('#url').val(result.response);//后端返回的上传文件路径
            }
        }
    });

5.服务器配置参数
添加nginx3个参数：请求时间
fastcgi_connect_timeout 120s;
fastcgi_send_timeout 120s;
fastcgi_read_timeout 120s;
修改php.ini 3个参数：文件大小
memory_limit = 300M
post_max_size = 300M
upload_max_filesize =300M
6.实现结果
