sharepoint rest api Add ListItem 报错

Recently, I was trying to create a list item using Rest API on Sharepoint 2013. I got the following error message

“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.”

}

Solution:

I found the solution for the above issue, most likely this error occurs since form digest has been expired on the page. In that case you could acquire a new form digest value by making a POST request to /_api/contextinfo endpoint. I’ve implemented the helper method for retrieving form digest.

Example :

function getFormDigest(siteUrl) {

return $.ajax({

url: siteUrl + “/_api/contextinfo”,

method: “POST”,

headers: { “Accept”: “application/json; odata=verbose” }

});

}

function createListItem(siteUrl, listName, itemProperties) {

var itemType = getItemTypeForListName(listName);

itemProperties[“__metadata”] = { “type”: itemType };

return getFormDigest(siteUrl).then(function (data) {

return $.ajax({

url: siteUrl + “/_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

}

});

}

//Fetch metadata for list item

function getItemTypeForListName(name) {

return “SP.Data.” + name.charAt(0).toUpperCase() + name.split(” “).join(“”).slice(1) + “ListItem”;

}

//Create a list item

var itemProperties = {‘Title’: ‘Title 1’};

createListItem(_spPageContextInfo.webAbsoluteUrl, ‘Demo List’, itemProperties)

.done(function (data) {

console.log(‘Item has been added successfully’);

})

.fail(function (error) {

console.log(JSON.stringify(error));

});

Usage :

var itemProperties = {‘Title’: ‘Title 1’};

createListItem(_spPageContextInfo.webAbsoluteUrl, ‘Test List’, itemProperties);
