Sharepoint 2013通过REST API:错误403在尝试创建项目时被禁止

Question

我正在尝试使用Sharepoint 2013上的其余api创建一个简单的列表项.我的代码:

$.ajax({
    url: siteUrl + "/_api/web/lists/getByTitle('internal_Listname')/items",
    type: "POST",
    contentType: "application/json;odata=verbose",
    data: JSON.stringify({
         '__metadata': {
            'type': 'SP.Data.internal_ListnameListItem',
         },
         'K1F1': k1f1Result,
    }),
    headers: {
        "accept": "application/json;odata=verbose",
        "X-RequestDigest": $("#__REQUESTDIGEST").val(),
    },
    success: function (data) {
        console.log("done");
    },
    error: function (err) {
        console.log(JSON.stringify(err));
    }
});

尝试发送数据时,我收到403"禁止"错误.

"error":{
   "code":"-2130575251, Microsoft.SharePoint.SPException",
   "message":{
        "lang":"en-US",
        "value":"The security validation for this page is invalid and might be corrupted. Please use your web browser's Back button to try your operation again."
    }
}

• 我对此站点和列表拥有完全管理员权限.

由于表单摘要已在页面上过期,因此很可能发生此错误.

在这种情况下,您可以通过POST向/_api/contextinfo端点发出请求来获取新的表单摘要值.

例

function getFormDigest(webUrl) {
    return $.ajax({
        url: webUrl + "/_api/contextinfo",
        method: "POST",
        headers: { "Accept": "application/json; odata=verbose" }
    });
}


function createListItem(webUrl, listName, itemProperties) {
    return getFormDigest(webUrl).then(function (data) {

        return $.ajax({
            url: webUrl + "/_api/web/lists/getbytitle('" + listName + "')/items",
            type: "POST",
            processData: false,
            contentType: "application/json;odata=verbose",
            data: JSON.stringify(itemProperties),
            headers: {
                "Accept": "application/json;odata=verbose",
                "X-RequestDigest": data.d.GetContextWebInformation.FormDigestValue
            }
        });
    });
}

用法

//Create a Task item
var taskProperties = {
    '__metadata': { 'type': 'SP.Data.WorkflowTasksItem' },
    'Title': 'Order approval'
};

createListItem(_spPageContextInfo.webAbsoluteUrl, 'Workflow Tasks', taskProperties)
.done(function (data) {
    console.log('Task has been created successfully');
})
.fail(function (error) {
    console.log(JSON.stringify(error));
});

几天前找到了解决方案：我忘记将请求摘要表单添加到正文中。它应该具有以下结构；

<form runat="server">
   <SharePoint:FormDigest ID="FormDigest1" runat="server"></SharePoint:FormDigest>
</form>
