Lambda：亚马逊s3直接上传错误签名不匹配-Lambda:Amazons3directuploaderrorsignaturedoesnotmatch

I want to upload image files to AWS s3 bucket by using pre-signed URLs, But I'm getting an error shown in the screen shot, I've followed the post from this page s3 direct file upload, I would like to know what mistake I'm making and also I want to know whether this is server side issue or there should I use some different approach for making put request to 'pre-signed' URL, thanks ahead.

我想通过使用预先签名的URL将图像文件上传到AWS s3存储桶，但是我在屏幕截图中显示错误，我已经按照此页面的帖子s3直接上传文件，我想知道是什么错误我正在制作，而且我想知道这是否是服务器方面的问题，或者我应该使用一些不同的方法来向'预先签名'的URL提出请求，谢谢你。
