RetrievePrincipleAccess AccessRights 从 Web API 始终为空 - Dynamics CRM 2016

Question

我无法检索对 CRM 中特定记录的访问权限。

我正在按照此处的建议使用 RetrievePrincipalAccess Web API 调用：

https://msdn.microsoft.com/en-us/library/mt683539.aspx

但是，AccessRights 字段始终为空。

无论用户是系统管理员还是任何安全角色，都会发生这种情况。

这是我的代码：

var crmTesting = {
tests: {
    getUserPrivilegesForRecord: function () {
        var recordId = Xrm.Page.data.entity.getId().replace('{', '').replace('}', '');
        var userId = Xrm.Page.context.getUserId().replace('{', '').replace('}', '');
        console.log(recordId);
        console.log(userId);
        crmTesting.api.retrievePrincipalAccess(userId, 'accounts', recordId, function (r) {
            console.log(r);
        });
    }
},
api: {
    retrievePrincipalAccess: function (userId, entityPluralName, entityId, callback) {
        if (!this.context.loaded) {
            this.context.init();
        }
        var url = 'systemusers(' + userId 
            + ")/Microsoft.Dynamics.CRM.RetrievePrincipalAccess(Target=@tid)?@tid={'@odata.id':'" 
            + entityPluralName + '(' + entityId + ")'}";
        this.get(url, callback);
    },
    get: function (url, callback, error) {
        if (!this.context.loaded) {
            this.context.init();
        }
        var xhr = new XMLHttpRequest();
        xhr.open('GET', this.context.clientUrl + '/api/data/v8.1/' + url);
        xhr.setRequestHeader('Accept', 'application/json');
        xhr.setRequestHeader('Prefer', 'odata.include-annotation=OData.Community.Display.V1.FormattedValue');
        xhr.setRequestHeader('OData-MaxVersion', '4.0');
        xhr.setRequestHeader('OData-Version', '4.0');
        xhr.onload = function () {
            if (xhr.status == 200) {
                if (typeof callback != 'undefined') {
                    var result = JSON.parse(xhr.responseText);
                    callback(result);
                }
            }
            else if (xhr.status == 204) {
                if (typeof callback != 'undefined') {
                    callback();
                }
            }
            else {
                console.error(xhr.responseText);
                if (typeof error != 'undefined') {
                    error(xhr.responseText);
                }
                return;
            }
        };
        xhr.send();
    },
    post: function (url, data, callback, error) {
        if (!this.context.loaded) {
            this.context.init();
        }
        var xhr = new XMLHttpRequest();
        xhr.open('POST', this.context.clientUrl + '/api/data/v8.1/' + url);
        xhr.setRequestHeader('Accept', 'application/json');
        xhr.setRequestHeader('Context-Type', 'application/json; charset=utf-8');
        xhr.setRequestHeader('OData-MaxVersion', '4.0');
        xhr.setRequestHeader('OData-Version', '4.0');
        xhr.onload = function () {
            if (xhr.status == 200 || xhr.status == 204) {
                try {
                    var response = JSON.parse(xhr.responseText);
                    if (typeof callback != 'undefined') {
                        callback(response);
                    }
                }
                catch (e) {
                    console.log('Request successful. No response.');
                }
                return;
            }
            else {
                console.error(xhr.responseText);
                if (typeof error != 'undefined') {
                    error(xhr.responseText);
                }
            }
        };
        if (typeof data == 'string') {
            xhr.send(data);
        }
        else {
            xhr.send(JSON.stringify(data));
        }
    },
    context: {
        loaded: false,
        context: {},
        clientUrl: '',
        init: function () {
            this.context = this.getContext();
            this.clientUrl = this.context.getClientUrl();
            this.loaded = true;
        },
        getContext: function () {
            if (typeof GetGlobalContext != 'undefined') {
                return GetGlobalContext();
            }
            else if (typeof Xrm != 'undefined') {
                return Xrm.Page.context;
            }
            else {
                throw new Error('Context is not available.');
            }
        }
    }   
}
};

任何关于为什么会发生这种情况的帮助将不胜感激。

不确定这是 Microsoft 的错误还是我做错了什么所以想在这里验证它。

我确认这是本地 Dynamics CRM 2016（在 8.1.1.1005 上测试）中的错误。

我最终创建了一个自定义工作流 activity 和一个操作。

自定义工作流程activity

创建并注册新的自定义工作流程activity

using Microsoft.Crm.Sdk.Messages;
using Microsoft.Xrm.Sdk;
using Microsoft.Xrm.Sdk.Workflow;
using System;
using System.Activities;

namespace ****.WF.CheckRecordPermissions
{
    public class CheckRecordPermissions : CodeActivity
    {

        [Input("Entity logical name (if null use context)")]
        public InArgument<string> entityP { get; set; }

        [Input("Entity GUID (if null use context)")]
        public InArgument<string> guidP { get; set; }

        [Input("User to check (if null use context)")]
        [ReferenceTarget("systemuser")]
        public InArgument<EntityReference> userP { get; set; }

        [Output("Create permission")]
        public OutArgument<bool> cpP { get; set; }

        [Output("Read permission")]
        public OutArgument<bool> rpP { get; set; }

        [Output("Write permission")]
        public OutArgument<bool> wpP { get; set; }

        [Output("Delete permission")]
        public OutArgument<bool> dpP { get; set; }

        [Output("Append permission")]
        public OutArgument<bool> apP { get; set; }

        [Output("AppendTo permission")]
        public OutArgument<bool> atpP { get; set; }

        [Output("Assing permission")]
        public OutArgument<bool> aspP { get; set; }

        [Output("Share permission")]
        public OutArgument<bool> shpP { get; set; }

        protected override void Execute(CodeActivityContext executionContext)
        {
            ITracingService tracer = executionContext.GetExtension<ITracingService>();
            IWorkflowContext context = executionContext.GetExtension<IWorkflowContext>();
            IOrganizationServiceFactory serviceFactory = executionContext.GetExtension<IOrganizationServiceFactory>();
            IOrganizationService service = serviceFactory.CreateOrganizationService(null);

            EntityReference target;

            String entity = entityP.Get(executionContext);
            String guid = guidP.Get(executionContext);

            if (!String.IsNullOrEmpty(entity) && !String.IsNullOrEmpty(guid))
                target = new EntityReference(entity, new Guid(guid));
            else
                target = new EntityReference(context.PrimaryEntityName, context.PrimaryEntityId);

            EntityReference user = userP.Get(executionContext);
            if (user == null)
                user = new EntityReference("systemuser", context.InitiatingUserId);

            RetrievePrincipalAccessRequest req = new RetrievePrincipalAccessRequest();
            req.Principal = user;
            req.Target = target;
            RetrievePrincipalAccessResponse resp = (RetrievePrincipalAccessResponse)service.Execute(req);

            cpP.Set(executionContext, resp.AccessRights.HasFlag(AccessRights.CreateAccess));
            rpP.Set(executionContext, resp.AccessRights.HasFlag(AccessRights.ReadAccess));
            wpP.Set(executionContext, resp.AccessRights.HasFlag(AccessRights.WriteAccess));
            dpP.Set(executionContext, resp.AccessRights.HasFlag(AccessRights.DeleteAccess));
            apP.Set(executionContext, resp.AccessRights.HasFlag(AccessRights.AppendAccess));
            atpP.Set(executionContext, resp.AccessRights.HasFlag(AccessRights.AppendToAccess));
            aspP.Set(executionContext, resp.AccessRights.HasFlag(AccessRights.AssignAccess));
            shpP.Set(executionContext, resp.AccessRights.HasFlag(AccessRights.ShareAccess));
        }
    }
}

自定义操作

在 SystemUser 实体上创建自定义操作。添加输入输出参数如下（抱歉截图中没有使用英文，我们是意大利语）：

调用操作

终于可以通过javascript调用动作了：

var readOnly;
var params = {
    "entita": Xrm.Page.data.entity.getEntityName(),
    "guid": Xrm.Page.data.entity.getId().slice(1, -1)
};
$.ajax({
    url: Xrm.Page.context.getClientUrl() + "/api/data/v8.1/systemusers(" + Xrm.Page.context.getUserId().slice(1, -1) + ")/Microsoft.Dynamics.CRM.new_controllaprivilegi",
    headers: {
        'Accept': 'application/json',
        'Content-Type': 'application/json'
    },
    data: JSON.stringify(params),
    type: "post",
    dataType: "json",
    async: false,
    success: function (_responseOfferta) {
        readOnly = !_responseOfferta["Write"];
    }
});

希望对您有所帮助！
