Include Signatures in URL
Last update：2022-04-15 18:00:02
you can also add your signatures to the URL by using query string parameters, which is useful when you want to express a request entirely in a URL. Others can use the the signed URL to access your OS resources temporarily without having your AccessKeySecret.
Example of signed URL
http://bucketName.s3-cn-east=1.wcsapi.com/keyName
?Signature=hXrFL6wBspF7fNE7lChnOIBEpE4%3D
&AWSAccessKeyId=db17ab5d18c137f786b67c490187317a0738f94a
&Expires=1639390003
Note:Line feeds are added for readability
Parameters
| Parameter Name | Required | Description |
|---|---|---|
| Expires | Yes | The time when the signed URL expires. Type: string If the time that OS receives the request is later than the value of this parameter, a request timeout error is returned. |
| AWSAccessKeyId | Yes | AK information. Type: string |
| Signature | Yes | The signature information. The following code shows the format of signature: Signature = urlencode(base64(hmacsha1(AccessKeySecret, VERB + “\n” + CONTENT-MD5 + “\n” + CONTENT-TYPE + “\n” + EXPIRES + “\n” + CanonicalizedOSSHeaders + CanonicalizedResource))) |
