/**
* PHP Server-Side Example for Fine Uploader S3.
* Maintained by Widen Enterprises.
*
* Note: This is the exact server-side code used by the S3 example
* on fineuploader.com.
*
* This example:
* - handles both CORS and non-CORS environments
* - handles delete file requests for both DELETE and POST methods
* - Performs basic inspections on the policy documents and REST headers before signing them
* - Ensures again the file size does not exceed the max (after file is in S3)
* - signs policy documents (simple uploads) and REST requests
* (chunked/multipart uploads)
*
* Requirements:
* - PHP 5.3 or newer
* - Amazon PHP SDK (only if utilizing the AWS SDK for deleting files or otherwise examining them)
*
* If you need to install the AWS SDK, see http://docs.aws.amazon.com/aws-sdk-php-2/guide/latest/installation.html.

答案 0 :(得分：2)
看起来当您复制并粘贴PHP示例服务器代码时，您忽略了调整某些值。在这种情况下，未修改handlePreflightedRequest方法以反映您的域。
应该是：
function handlePreflightedRequest() {
// If you are relying on CORS, you will need to adjust the allowed domain here.
header('Access-Control-Allow-Origin: http://typhooncloud.com');
}
此外，handlePreflightedRequest方法可能应重命名为handleCorsRequest以避免混淆。我刚刚在服务器仓库中完成了这个。但是，您并不需要这样做，因为它不会影响代码的行为。
答案 1 :(得分：1)
旁注。让我指出一个关键的区别。在javascript代码中编写sizeLimit: 5000000，但在PHP中编写$expectedMaxSize = 15000000。这些值必须完全匹配。
