Laravel + Plupload上传到S3的预检响应无效 - CORS

Question

我在Nginx服务器上测试一个上传到S3的plupload.整个项目以Laravel为基础.

问题是当我开始上传时,Chrome的控制台说:

XMLHttpRequest cannot load http://BUCKET.s3.amazonaws.com/. Response for preflight is invalid (redirect)

我已经尝试使用PHP头来启用CORS,但仍然会出现错误.

当前上传脚本:

<?php
$bucket = 'BUCKET';
$accessKeyId = '***************';
$secret = '********************************************';

$policy = base64_encode(json_encode(array(
        'expiration' => date('Y-m-d\TH:i:s.000\Z', strtotime('+1 day')),
        'conditions' => array(
                array('bucket' => $bucket),
                array('acl' => 'public-read'),
                array('starts-with', '$key', ''),
                array('starts-with', '$Content-Type', ''),
                array('starts-with', '$name', ''),
                array('starts-with', '$Filename', ''),
        )
)));

$signature = base64_encode(hash_hmac('sha1', $policy, $secret, true));
?>
....
<div id="uploader"></div>
....    
    <script>
        $(function () {
            $("#uploader").plupload({
                runtimes: 'html5',
                url: 'http://<?php echo $bucket; ?>.s3.amazonaws.com/',

                multipart: true,
                multipart_params: {
                    'key': '${filename}',
                    'Filename': '${filename}',
                    'acl': 'public-read',
                    'Content-Type': 'image/jpeg',
                    'AWSAccessKeyId': '<?php echo $accessKeyId; ?>',
                    'policy': '<?php echo $policy; ?>',
                    'signature': '<?php echo $signature; ?>'
                },

                file_data_name: 'file',
                filters: {
                    max_file_size: '10mb',
                    prevent_duplicates: true,
                    mime_types: [
                        {title: "Image files", extensions: "jpg,jpeg"}
                    ]
                }
            });
        });
    </script>
....

我检查了这个以在Nginx上启用CORS,但事实是当我将该片段放在我的位置/块上时,它在我打开URL时返回404.

我的Nginx站点配置文件:

server {
    listen 80;
    server_name myserver.com;
    root /usr/share/nginx/myserver/public;

    index index.html index.htm index.php;

    charset utf-8;

    location / {
        try_files $uri $uri/ /index.php?$query_string;
    }

    location = /favicon.ico { access_log off; log_not_found off; }
    location = /robots.txt  { access_log off; log_not_found off; }

    access_log off;
    error_log  /var/log/nginx/myapp-error.log error;

    sendfile off;

    client_max_body_size 100m;

    location ~ \.php$ {
        fastcgi_split_path_info ^(.+\.php)(/.+)$;
        fastcgi_pass unix:/var/run/php5-fpm.sock;
        fastcgi_index index.php;
        include fastcgi_params;
        fastcgi_param SCRIPT_FILENAME $document_root$fastcgi_script_name;
        fastcgi_intercept_errors off;
        fastcgi_buffer_size 16k;
        fastcgi_buffers 4 16k;
    }

    location ~ /\.ht {
        deny all;
    }

}

非常感谢

我找到了一种方法来实现它，效果很差。深入研究http://laravel.com/docs/master/filesystem我没有找到让 Plupload 工作的有效答案。否则，我发现一个糟糕的解决方案使用：

<input type="file" name="files[]" multiple>

并使用类似的东西：

foreach($request->file("files") as $file) {
        Storage::put(
            'test'.rand(1,100),
            file_get_contents($file->getRealPath())
        );
    };

在我的控制器中，可以将多个文件上传到 S3。但它不是异步的，而且用户体验也更差。

我将继续努力最终启用 Plupload。我将在这里发布更新。
