[sharepoint]文档库，文件夹授权

写在前面

在项目中用到了文档库授权的方法，这里将查询到的方式总结一下。

涉及到的方法

在逻辑中用到的方法。

另外加个rest api，这种方式也可以进行授权。

_api/web/lists/getByTitle('" + LibraryName + "')/RoleAssignments/addroleassignment(principalid=" + userId + ",roledefid=" + roleDefinitionId + ")"

 总结

 在对文档库或者文件夹进行授权的过程，总是磕磕碰碰，不管怎么，最后还是实现了。总结在这里，方便以后查询
