通过.Net代码使用REST API进行模拟 [英] Impersonation using REST API through .Net code

问题描述

Hi Experts，

Hi Experts,

我正在开发一个应用程序，它使用SharePoint加载项在SharePoint中创建/上载/共享文件。我正在使用Rest API做这一切。

I am developing an application, that uses SharePoint Add-ins to Create/Upload/Share files in SharePoint. I am doing all this using the Rest API.

我的问题是，将来我会要求用户登录我的应用程序并显示列表/文件，我仍然会继续使用SharePoint加载项创建/上载/共享文件。但是，我想根据登录用户
冒充请求，并根据他拥有的权限向他显示允许给他的文件/列表。

My question is, in future I'll ask the user to login into my application and show the lists/files, and I would still continue using the SharePoint Add-Ins to Create/Upload/Share files. But, I'd want to impersonate the request based on the logged-in user and show him the files/lists that are allowed to him based on the permissions that he has.

对此的任何指导都会非常感激。

Any guidance on this would really be appreciated.

谢谢！

推荐答案

您可以在Rest API中查看特定用户帐户的列表用户权限：

You can check the list user permission for a specific user account like this in Rest API:

function getListUserEffectivePermissions(webUrl,listTitle, accountName) 
{
    var endpointUrl = webUrl +  "/_api/web/lists/getbytitle('" + listTitle + "')/getusereffectivepermissions(@u)?@u='" + encodeURIComponent(accountName) + "'";
    return

.getJSON（endpointUrl）;
}

函数parseBasePermissions（value）
{
var permissions = new SP.BasePermissions（）;
permissions.initPropertiesFromJson（value）;
var permLevels = [];
for（SP.PermissionKind.prototype中的var permLevelName）{
if（SP.PermissionKind.hasOwnProperty（permLevelName））{
var permLevel = SP.PermissionKind.parse（permLevelName）;
if（permissions.has（permLevel））{
permLevels.push（permLevelName）;
}
}
}
返回permLevels;
}

.getJSON(endpointUrl); } function parseBasePermissions(value) { var permissions = new SP.BasePermissions(); permissions.initPropertiesFromJson(value); var permLevels = []; for(var permLevelName in SP.PermissionKind.prototype) { if (SP.PermissionKind.hasOwnProperty(permLevelName)) { var permLevel = SP.PermissionKind.parse(permLevelName); if(permissions.has(permLevel)){ permLevels.push(permLevelName); } } } return permLevels; }

用法：

var webUrl = _spPageContextInfo.webAbsoluteUrl;  
getListUserEffectivePermissions(webUrl,'Documents','i:0#.f|membership|[e-mail]')
        .done(function(data){
            var roles = parseBasePermissions(data);
            console.log(roles); 
        });
		

结果：

["emptyMask", "viewListItems", "addListItems", "editListItems", "deleteListItems", "openItems", "viewVersions", "deleteVersions", "managePersonalViews", "viewFormPages", "open", "viewPages", "createSSCSite", "browseDirectories", "browseUserInfo", "addDelPrivateWebParts", "updatePersonalWebParts", "useClientIntegration", "useRemoteAPIs", "createAlerts", "editMyUserInfo"]

如果想通过.NET代码模拟Rest API，可以使用HttpClient Class来实现：

And if want to impersonate Rest API through .NET code, you could use HttpClient Class to achieve:

在C＃托管代码中使用SharePoint 2013 REST API
