使用Fine Uploader时出现响应500错误

Question

使用Fine Uploader库时出现一些错误，但无法找出原因。

这是发生了什么事。这是我用我的网页上的代码：

var uploader = new qq.s3.FineUploader({ 
    element: document.getElementById("fineUploader"), 
    request: { 
     endpoint: "mybucket.amazonaws.com", 
     accessKey: "ABCDEFGHIJKLMNOPQRS" 
    }, 
    signature: { 
     endpoint: "/wp-content/themes/zone/vendor/fineuploader/php-s3-server/endpoint.php" 
    }, 
    uploadSuccess: { 
     endpoint: "/wp-content/themes/zone/vendor/fineuploader/php-s3-server/endpoint.php?success" 
    }, 
    objectProperties: { 
     key: "filename" 
    }, 
    iframeSupport: { 
     localBlankPagePath: "/wp-content/themes/zone/success.html" 
    }, 
    cors: { 
     expected: true 
    }, 
    chunking: { 
     enabled: true 
    }, 
    resume: { 
     enabled: true 
    }, 
}); 

此代码是上传文件，以S3但我在页面上得到一个错误：

在上传的UI，我在红色框中收到一条错误消息，指出“上传失败”。

在开发者控制台，我得到：

s3.fine-uploader.js:256 [Fine Uploader 5.3.2] Your server indicated failure in its upload success request response for id 0! 

什么奇怪的是，该文件被上传。已通过检查存储桶来确认这一点。这似乎是与uploadSuccess：函数有一些错误。如果有问题，我在本地使用MAMP Pro。

任何想法可能发生什么？谢谢！

500错误来自您的签名端点，当您的服务器尝试处理Fine Uploader POST“成功”请求时发生这种情况，这表明文件在S3中安全。连接到该端点服务器端的代码在某种程度上失败。您需要检查您的服务器日志以确定具体的故障是什么。也许你试图在S3调用服务器端作为此调用的一部分，并且关联的IAM用户没有适当的权限。可能是这个，或者其他许多问题。
