strange access log for query args

[michael2008]

Describe the bug

A clear and concise description of what the bug is.

To Reproduce
For url-encoded parameters, the access log will produce something like:
Object=tmp%!F(MISSING)test_oss%!F(MISSING)test_file_1734870290111317000&Range=bytes%!D(MISSING)1040732-7470859&Timeout=30

Expected behavior
print decoded query args.

One possible way to fix is:

TagQueryStringParams: func(output Buffer, c *app.RequestContext, data *Data, extraParam string) (int, error) {
		var list []string
		args := c.Request.URI().QueryArgs()
		args.VisitAll(func(key, value []byte) {
			list = append(list, string(key)+"="+string(value))
		})
		s := strings.Join(list, "&")
		return output.WriteString(s)
	},
