SharePoint REST API - 使用REST接口對列表設置自定義權限

博客地址:http://blog.csdn.net/FoxDavejavascript

SharePoint網站、列表和列表項都屬於SecurableObject類型。默認狀況下,一個安全對象繼承父級的權限。對一個對象設置自定義權限,你須要打破它從父級的繼承,經過增刪role assignments來自定義權限。css

本篇一樣會以代碼示例來講明如何在列表上設置自定義權限,而後再更改一個組的權限。該示例使用REST服務來:java

>獲取目標組的ID。該示例經過目標組的ID來獲取當前列表上的組所具備的角色綁定,並向列表添加新的角色。web

>獲取爲組定義的新的權限的角色定義的ID,該ID用來向列表添加新的角色。該示例使用已存在的角色定義來定義新的角色,固然你也能夠選擇建立一個新的角色定義。ajax

>使用BreakRoleInheritance方法打破列表上的權限繼承。該示例打破了列表的權限繼承並保留當前的權限設置。(在打破權限繼承的時候,也能夠選擇不保留當前的設置而只把當前用戶添加到管理權限級別。)json

>經過發送DELETE方法請求到role assignment端點來移除列表上的組當前的role assignment。(若是你在打破權限繼承的時候沒有保留現有設置,能夠忽略此步。)api

>使用AddRoleAssignment方法向組添加一個role assignment到目標列表,該操做會將組綁定到一個角色定義並將該角色添加到列表上。跨域

前置條件安全

>SharePoint開發環境markdown

>帶有Office Developer Tools的Visual Studio 2013或更高版本

此外還須要設置Add-in在網站範圍內的徹底控制權限,只有具備足夠權限來更改列表權限的用戶(如網站全部者)能夠執行這個add-in。

示例:使用REST接口在列表上自定義權限

下面的示例展現了一個SharePoint承載的Add-in中的App.js文件的內容。第一個示例使用JavaScript跨域庫來構建和發送HTTP請求,第二個示例使用jQuery AJAX請求。在你執行代碼以前,須要把佔位符的值替換成真實的值。

示例一:跨域庫請求

'use strict';

// Change placeholder values before you run this code.
var listTitle = 'List 1';
var groupName = 'Group A';
var targetRoleDefinitionName = 'Contribute';
var appweburl;
var hostweburl;
var executor;
var groupId;
var targetRoleDefinitionId;

$(document).ready( function() {

    //Get the URI decoded URLs.
    hostweburl = decodeURIComponent(getQueryStringParameter("SPHostUrl"));
    appweburl = decodeURIComponent(getQueryStringParameter("SPAppWebUrl"));

    // Load the cross-domain library file and continue to the custom code.
    var scriptbase = hostweburl + "/_layouts/15/";
    $.getScript(scriptbase + "SP.RequestExecutor.js", getTargetGroupId);
});

// Get the ID of the target group.
function getTargetGroupId() {
    executor = new SP.RequestExecutor(appweburl);
    var endpointUri = appweburl + "/_api/SP.AppContextSite(@target)/web/sitegroups/getbyname('";
    endpointUri += groupName + "')/id" + "?@target='" + hostweburl + "'";

    executor.executeAsync({
        url: endpointUri,
        method: 'GET',
        headers: { 'accept':'application/json;odata=verbose' },
        success: function(responseData) {
            var jsonObject = JSON.parse(responseData.body);
            groupId = jsonObject.d.Id;
            getTargetRoleDefinitionId();
        },
        error: errorHandler
   });
}

// Get the ID of the role definition that defines the permissions
// you want to assign to the group.
function getTargetRoleDefinitionId() {
    var endpointUri = appweburl + "/_api/SP.AppContextSite(@target)/web/roledefinitions/getbyname('";
    endpointUri += targetRoleDefinitionName + "')/id" + "?@target='" + hostweburl + "'";

    executor.executeAsync({
        url: endpointUri,
        method: 'GET',
        headers: { 'accept':'application/json;odata=verbose' },
        success: function(responseData) {
            var jsonObject = JSON.parse(responseData.body)
            targetRoleDefinitionId = jsonObject.d.Id;
            breakRoleInheritanceOfList();
        },
        error: errorHandler
    });
}

// Break role inheritance on the list.
function breakRoleInheritanceOfList() {
    var endpointUri = appweburl + "/_api/SP.AppContextSite(@target)/web/lists/getbytitle('";
    endpointUri += listTitle + "')/breakroleinheritance(true)?@target='" + hostweburl + "'";

    executor.executeAsync({
        url: endpointUri,
        method: 'POST',
        headers: { 'X-RequestDigest':$('#__REQUESTDIGEST').val() },
        success: deleteCurrentRoleForGroup,
        error: errorHandler
    });
}

// Remove the current role assignment for the group on the list.
function deleteCurrentRoleForGroup() {
    var endpointUri = appweburl + "/_api/SP.AppContextSite(@target)/web/lists/getbytitle('";
    endpointUri += listTitle + "')/roleassignments/getbyprincipalid('" + groupId + "')?@target='" + hostweburl + "'";

    executor.executeAsync({
        url: endpointUri,
        method: 'POST',
        headers: { 
            'X-RequestDigest':$('#__REQUESTDIGEST').val(),
            'X-HTTP-Method':'DELETE'
        },
        success: setNewPermissionsForGroup,
        error: errorHandler
    });
}

// Add the new role assignment for the group on the list.
function setNewPermissionsForGroup() {
    var endpointUri = appweburl + "/_api/SP.AppContextSite(@target)/web/lists/getbytitle('";
    endpointUri += listTitle + "')/roleassignments/addroleassignment(principalid=" + groupId;
    endpointUri += ",roledefid=" + targetRoleDefinitionId + ")?@target='" + hostweburl + "'";

    executor.executeAsync({
        url: endpointUri,
        method: 'POST',
        headers: { 'X-RequestDigest':$('#__REQUESTDIGEST').val() },
        success: successHandler,
        error: errorHandler
    });
}

// Get parameters from the query string.
// For production purposes you may want to use a library to handle the query string.
function getQueryStringParameter(paramToRetrieve) {
    var params = document.URL.split("?")[1].split("&");
    for (var i = 0; i < params.length; i = i + 1) {
        var singleParam = params[i].split("=");
        if (singleParam[0] == paramToRetrieve) return singleParam[1];
    }
}

function successHandler() {
    alert('Request succeeded.');
} 

function errorHandler(xhr, ajaxOptions, thrownError) {
    alert('Request failed: ' + xhr.status + '\n' + thrownError + '\n' + xhr.responseText);
}
示例二:jQuery AJAX請求

var groupName = 'Group A';
var targetRoleDefinitionName = 'Contribute';
var groupId;

    getTargetGroupId();
});

// Get the ID of the target group.
function getTargetGroupId() {
    $.ajax({
        url: siteUrl + '/_api/web/sitegroups/getbyname(\'' + groupName + '\')/id',
        type: 'GET',
        headers: { 'accept':'application/json;odata=verbose' },
        success: function(responseData) {
            groupId = responseData.d.Id;
            getTargetRoleDefinitionId();
        },
        error: errorHandler
   });
}

// Get the ID of the role definition that defines the permissions
// you want to assign to the group.
function getTargetRoleDefinitionId() {
    $.ajax({
        url: siteUrl + '/_api/web/roledefinitions/getbyname(\''
            + targetRoleDefinitionName + '\')/id',

        type: 'POST',
        headers: { 'X-RequestDigest':$('#__REQUESTDIGEST').val() },
        success: deleteCurrentRoleForGroup,

    $.ajax({
        url: siteUrl + '/_api/web/lists/getbytitle(\'' + listTitle
            + '\')/roleassignments/addroleassignment(principalid='

}
