Problem description

The x-oss-signature parameter in the request is empty.

Causes

You initiate a request that includes the V2 signature in the URL. However, the x-oss-signature parameter in the request is empty.

Examples

The following code provides an example:

GET /oss.jpg?x-oss-signature-verion=OSS2&x-oss-expires=1141889120&x-oss-access-key-id=nz2pc56s936****&x-oss-signature= HTTP/1.1
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Date: Tue, 20 Dec 2022 08:48:18 GMT

The value of the x-oss-signature parameter is the signature calculated by using the signature algorithm.

Solutions

When you initiate a request that includes the V2 signature in the URL, make sure that the following fields are included in the request: x-oss-signature-verion, x-oss-access-key-id, x-oss-signature-verion, and x-oss-signature. Example:

GET /oss.jpg?x-oss-signature-verion=OSS2&x-oss-access-key-id=nz2pc56s936****&x-oss-expires=1141889120&x-oss-signature=a8***I0= HTTP/1.1
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
