冷融Amazon S3-设置内容类型? [英] Coldfusion & Amazon S3 - Setting the Content Type?

问题描述

我已经将Amazon S3用于内容已有一段时间了，但是我遇到了一个需要设置上传图像的内容类型的实例(需要在上传时执行此操作).我已经尝试了一些方法，但是似乎无法确定StoreSetMetaData的正确语法.

I've used Amazon S3 for content for a while now, but I've just run across an instance where I need to set the content type for uploaded images (need to do this at the point of upload). I've tried a few things, but can't seem to nail the correct syntax for StoreSetMetaData.

这就是我现在正在做的事情...

This is how I'm doing it right now...

<cfset meta = [{content_type="Image"}]>

<cfset StoreSetMetadata("s3://mybucket/#bgfull#", "#meta#")>

其余的代码不是必需的，因此我只粘贴了相关的两行.

The rest of the code isnt necessary, so I've just pasted in the relevant 2 lines.

使用这种语法，出现以下错误；

Using this syntax, I get the following error;

"500您试图将类型为coldfusion.runtime.Array的标量变量取消引用为具有成员的结构."

"500 You have attempted to dereference a scalar variable of type class coldfusion.runtime.Array as a structure with members."

非常感谢指针！我无法为此找到一个语法示例.

Pointers much appreciated! I haven't been able to track down a single syntax example for this.

推荐答案

根据

According to the online documentation of StoreSetMetadata the second argument is of type struct, and not of type array.

尝试

<cfset meta = {content_type="Image"}>

<cfset StoreSetMetadata("s3://mybucket/#bgfull#", meta)>
