Question

我正在尝试在s3中将对象上传到存储桶中。我正在使用REST API（没有SDK），我已经按照文档进行操作： https://docs.aws.amazon.com/AmazonS3/latest/API/sig-v4-header-based-auth.html

和

https://docs.aws.amazon.com/AmazonS3/latest/API/RESTObjectPUT.html

此文档中：

示例：PUT对象（部分）

对于内容为“欢迎使用Amazon S3”的文本文件，我的规范应该看起来像这样：

PUT
/test%24file.text

当我执行请求（更新时间和签名）时，出现以下错误

<?xml version="1.0" encoding="UTF-8"?>

似乎规范请求不接受名称（我尝试了具有相同结果的不同选项），因为它的字符串像这样响应（）

代替

/test%24file.text

我不明白如何传递文件名，或者是否缺少其他内容。

我将所有标头设置如下：

    request.setMethod('PUT');
    request.setEndpoint(canonicalUriFor);
    request.setHeader('Host', 'mulesofttdx19.s3-us-west-2.amazonaws.com');
    request.setHeader('Date', iso_aws_DateTime);
    request.setHeader('Authorization', strAuthorizationHeader);
    request.setHeader('x-amz-date',iso8601time);
    request.setHeader('x-amz-storage-class','REDUCED_REDUNDANCY');
    request.setHeader('X-Amz-Content-Sha256',NewAttachmentSync.hexEncodedHash(payload));
