fix: Unit tests fail in component package

[leemos-xx]

What this PR does:
在components/file/s3/qiniu目录的单测中，使用到http.Get方法向example.com发起请求，导致部分地区无法访问该域名时，会出现单测无法通过的情况。目前通过对http的请求进行mock，来避免发起真实的请求。

Fixes #528

Looks good to me. The httpmock package is interesting and useful.
Please fix the CI error by

cd components
go mod tidy

and then git add the modified go.sum
