Problem description

When you use an earlier version of the image service to add a watermark to an image, the specified watermark parameters are in an invalid format.

Cause

The watermark parameters are not in the &<key>=<value> format. In this format, & links parameters, <key> is the parameter name, and <value> is the parameter value.

Examples

GET /example_image@watermark=&object=cGFuZGEucG5n&y=50 HTTP/1.1
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Date: Fri, 03 Feb 2023 03:41:49 GMT
Content-Type: application/xml

In the preceding request, the watermark parameter is missing a <value>. This causes the error.

GET /example_image@watermark=1&object=cGFuZGEucG5n&y50 HTTP/1.1
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Date: Fri, 03 Feb 2023 03:41:49 GMT
Content-Type: application/xml

In the preceding request, the y50 parameter is missing an = sign. This causes the error.

GET /example_image@watermark=1&object=cGFuZGEucG5n&y=zero HTTP/1.1
Host: oss-example.oss-cn-hangzhou.aliyuncs.com
Date: Fri, 03 Feb 2023 03:41:49 GMT
Content-Type: application/xml

In the preceding request, the value zero for the y parameter does not meet the data type requirement. This causes the error.

Solution

Specify the image watermark parameters in the request string in the required format.
