Create File, Pull Request and More Examples

Aside from tests which most tend to ignore and go directly with actual testing, it would be nice to have more actual api examples to get a handle or familiarity with the api and perhaps leave the authentication blank if it is required on some to be filled out.

检查仓库中现有的测试和 API 示例，以确定当前示例是如何呈现的。添加用于创建文件、pull request 和执行其他 API 操作的实用示例；在需要时将身份验证值留空；当这些示例清楚地展示测试之外的用法时，即视为完成。
