csom - 没有使用 JSOM PS.ProjectContext get_projects 获得任何项目

Question

在Microsoft Project Server Web 应用程序中，我正在尝试使用JSOM获取项目列表。

我正在关注这些示例中的代码：

• https://docs.microsoft.com/en-us/office/client-developer/project/create-retrieve-update-delete-projects-using-project-server-javascript
• https://docs.microsoft.com/en-us/sharepoint/dev/sp-add-ins/complete-basic-operations-using-javascript-library-code-in-sharepoint
• https://sharepoint.stackexchange.com/questions/133935/get-project-custom-fields-project-server
• https://sharepoint.stackexchange.com/questions/76484/project-online-2013-jsom-napa-cannot-find-resource-for-the-request-processquer?rq=1

这就是我要测试的内容：

var projectContext = PS.ProjectContext.get_current();
var projects = projectContext.get_projects();
projectContext.load(projects, "Include(Name)");
projectContext.executeQueryAsync(IterateThroughProjects, handleError);

function IterateThroughProjects(response) {
    var enumerator = projects.getEnumerator();
    var i = 0;
    while (enumerator.moveNext()) {
        i++;
        var project = enumerator.get_current();
        console.log("Name: " + project.get_name());
    }
    console.log("Done. " + i + " projects found.");
}

function handleError(sender, args) { 
    console.log("Request failed: " + args.get_message()); 
}

该脚本运行没有任何错误，但结果始终是完成。找到 0 个项目。即使 PWA 中有已发布的项目。

这是我从服务器得到的响应：

[
    {"SchemaVersion":"15.0.0.0","LibraryVersion":"16.0.4756.1000","ErrorInfo":null,"TraceCorrelationId":"fcde4d9f-9755-2050-31d1-da0833d8ce31"},
    362,
    {"_ObjectType_":"PS.ProjectCollection", "_Child_Items_":[]}
]

我尝试过Project Online、Project Server 2013和Project Server 2016。

我缺少 SharePoint 或 PWA 中的任何设置吗？有同样问题的人吗？

我的问题是我从SharePoint 应用程序运行此代码，并且应用程序清单不包含项目权限（http://sharepoint/projectserver/projects -> 读取）：

<?xml version="1.0" encoding="utf-8"?>
<App xmlns="http://schemas.microsoft.com/sharepoint/2012/app/manifest" ...>
    <Properties>...</Properties>
    <AppPrincipal>...</AppPrincipal>
    <RemoteEndpoints>...</RemoteEndpoints>
    <AppPermissionRequests>
        ...
      <AppPermissionRequest Scope="http://sharepoint/projectserver/projects" Right="Read" />
    </AppPermissionRequests>
</App>

添加权限后，我得到项目列表。
