在postman中使用put而不是post，并将文件的名称添加到url的末尾，如/foo.txt和s3之后的区域。之前，.amazonaws.com还删除授权中的区域。
示例：https://test.s3.us-east-1.amazonaws.com/test.csv

这是邮递员应用本身的问题，我刚刚用Node和x content-sha256头向AWS发送了http请求。
由于这个答案过于简单和简短，我将在这里添加工作的JS代码：
import fs from 'fs/promises'
import FormData from 'form-data'
import fetch from 'node-fetch'
async function postToAWS() {
const blob = fs.readFile('test.jpeg')
const filename = 'test.jpeg'
const bodyForm = new FormData()
bodyForm.append('file', blob, filename)
const response = await fetch('https://reddit-uploaded-media.s3-accelerate.amazonaws.com', {
method: 'POST',
body: bodyForm,
headers: {
'x-amz-content-sha256': ''
}
})
