Amazon web services 使用ColdFusion 2016 CFC上传图像AWS S3

我试图将一个图像上传到AWS S3存储桶，但我使用的方法是，我的密钥和访问代码导致SignatureDesNotMatch。我用这个例子作为我的参考点。提前感谢您的帮助

Cffile action=上传将在S3上运行。你为什么要这么费解？@JackPilowsky已经尝试过了，但是我得到了一个错误“文件上传操作需要表单使用enctype=“multipart/form data”。“任何建议都将不胜感激！（Edit）@ChaseCabrera-Action=upload假设您希望获取post结果（包含文件上载）并将文件发布到操作页面上的S3。这就是你想做的吗？如果没有，请尝试action=copy，FileCopy（source，destination），等等。这个概述是针对CF9的，但应该给您一个要点：如果您这样做，那么destination属性中就不需要S3凭据。将它们放在Application.cfc配置中，例如this.s3={accessKeyId=“”，awsSecretKey=“”}；上载文件的表单需要enctype=“multipart/form data”属性。@ChaseCabrera
