我有下一个场景：
但是每次我有一个错误：

const axios = require('axios');
const AWS = require('aws-sdk')
const s3 = new AWS.S3({
accessKeyId: 'FakeKeyId',
secretAccessKey: 'xxxxxxxxxxxxxxxxxxxxxxxx',
region: 'eu-west-1'
});
const fs = require('fs');
const readFile = require('util').promisify(fs.readFile);
(async () => {
try {
const presignedS3Url = s3.getSignedUrl('putObject', {
Bucket: 'test-bucket-super',
Key: 'xxx/test.mp3'
});
const file = await readFile('./SampleAudio_0.4mb.mp3');
const axiosResponse = await axios.put(presignedS3Url, {
data: file,
});
console.info(axiosResponse)
} catch (e) {
console.error(e)
}
})();
但是我设法通过cURL上传文件
curl -X PUT -T ~/Downloads/SampleAudio_0.4mb.mp3 'https://test-bucket-super.s3.eu-west-1.amazonaws.com/xxx/test.mp3?AWSAccessKeyId=FakeKeyId&Expires=1577741900&Signature=9kPiC%2B85SEFp6g5C3nwEWe4TueU%3D' -v
这里的问题是，axios由于某种原因添加了默认Content-Type: application/json标头。这就是签名不匹配的原因。我不确定如何删除标题。
但是下面的工作对我来说是我content-type在签名生成期间所需要的。另外，在使用它时，我会包含相同的标头。
(async () => {
try {
const presignedS3Url = s3.getSignedUrl('putObject', {
Bucket: 'bucket-name',
Key: 'car.jpg',
ContentType: 'application/octet-stream'
});
const file = await readFile('./car.jpg');
const axiosResponse = await axios.put(presignedS3Url, {
data: file,
}, {
headers: {
'Content-Type': 'application/octet-stream'
}
});
console.info(axiosResponse)
} catch (e) {
console.error(e)
}
})();
