推荐答案

你可以尝试下面的代码块，它适用于较大的文件（> 2 MB）。

You can try below code block, it will work for larger files (>2 MBs).

//documentLibraryName :  Give your document library name 
//controlIdentifier :  Give your file upload control id 
function UploadFile(documentLibraryName, controlIdentifier) {
    var serverRelativeUrlToFolder = documentLibraryName;
    var fileInput =

（" [id ='" + controlIdentifier +"']"）;
if（fileInput.length == 1&& fileInput [0] .files！== null&& fileInput [0] .files.length）{
var fileName = fileInput [0 ] .files [0]。名称;
var reader = new FileReader（）;
reader.onload = function（e）{
var fileData = e.target.result;
var fileCollectionEndpoint = String.format（" {0} / _ api / web / GetFolderByServerRelativeUrl（'{1}'）/ Files" +" / add（overwrite = true，url ='{2}'） "，_ spPageContextInfo.webAbsoluteUrl，serverRelativeUrlToFolder，fileName）;

("[id='" + controlIdentifier + "']"); if (fileInput.length == 1 && fileInput[0].files !== null && fileInput[0].files.length) { var fileName = fileInput[0].files[0].name; var reader = new FileReader(); reader.onload = function(e) { var fileData = e.target.result; var fileCollectionEndpoint = String.format("{0}/_api/web/GetFolderByServerRelativeUrl('{1}')/Files" + "/add(overwrite=true, url='{2}')", _spPageContextInfo.webAbsoluteUrl, serverRelativeUrlToFolder, fileName);

.ajax（{
url：fileCollectionEndpoint，
method：" POST"，
binaryStringRequestBody：true，
data：fileData，
processData：false，
headers：{
" ACCEPT"：" application / json; odata = verbose"，
"X-RequestDigest"：

.ajax({ url: fileCollectionEndpoint, method: "POST", binaryStringRequestBody: true, data: fileData, processData: false, headers: { "ACCEPT": "application/json;odata=verbose", "X-RequestDigest":
