SPS中JSOM和SOAP 实现文件上传

一、HTML控件

    <input type="file" id="upFile" style="width:300px;"/>
    <div id="fileDisplayArea">
    </div>
    <input type="button" value="Upload" onclick="CreateFile()" />

二、FileCreationInformation 方式

        var file;
        var newFile;
        var fileCreateInfo;
        function CreateFile() {
            // Ensure the HTML5 FileReader API is supported
            if (window.FileReader) {
                input = document.getElementById("upFile");
                if (input) {
                    file = input.files[0];
                    fr = new FileReader();
                    fr.onload = receivedBinary;
                    fr.readAsDataURL(file);
                }
            }
            else {
                alert("The HTML5 FileSystem APIs are not fully supported in this browser.");
            }
        }

        // Callback function for onload event of FileReader
        function receivedBinary() {

            var clientContext = new SP.ClientContext.get_current();
            var oWebsite = clientContext.get_web();
            clientContext.load(oWebsite);
            var list = oWebsite.get_lists().getByTitle("Apptexfiles");

            fileCreateInfo = new SP.FileCreationInformation();
            fileCreateInfo.set_url(file.name);
            fileCreateInfo.set_overwrite(true);
            fileCreateInfo.set_content(new SP.Base64EncodedByteArray());

            // Read the binary contents of the base 64 data URL into a Uint8Array
            // Append the contents of this array to the SP.FileCreationInformation
            var arr = convertDataURIToBinary(this.result);
            for (var i = 0; i < arr.length; ++i) {
                fileCreateInfo.get_content().append(arr[i]);
            }

            // Upload the file to the root folder of the document library
            newFile = list.get_rootFolder().get_files().add(fileCreateInfo);

            clientContext.load(newFile, 'ListItemAllFields'); //'Include(ID, Title, FileRef)'
            clientContext.executeQueryAsync(onSuccess, onFailure);
        }

        function onSuccess() {
            // File successfully uploaded
            alert("Success!");
        }

        function onFailure() {
            // Error occurred
            alert("Request failed: " + arguments[1].get_message());
            console.log("Request failed: " + arguments[1].get_message());
        }

        // Utility function to remove base64 URL prefix and store base64-encoded string in a Uint8Array
        // Courtesy: https://gist.github.com/borismus/1032746
        function convertDataURIToBinary(dataURI) {
            var BASE64_MARKER = ';base64,';
            var base64Index = dataURI.indexOf(BASE64_MARKER) + BASE64_MARKER.length;
            var base64 = dataURI.substring(base64Index);
            var raw = window.atob(base64);
            var rawLength = raw.length;
            var array = new Uint8Array(new ArrayBuffer(rawLength));

            for (i = 0; i < rawLength; i++) {
                array[i] = raw.charCodeAt(i);
            }
            return array;
        }

三、SOAP 方式

        function ShowMailDialog() {
            var file = document.getElementById('upFile').files[0];
            if (file) {
                UploadFile(file);
            }
        }
        function UploadFile(readFile) {
            var reader = new FileReader();
            reader.readAsArrayBuffer(readFile); //array buffer
            reader.onprogress = updateProgress;
            reader.onload = loaded;
            reader.onerror = errorHandler;
        }
        function loaded(evt) {
            var fileString = evt.target.result;
            var X = _arrayBufferToBase64(fileString); // this is the mothod to convert Buffer array to Binary
            var fileInput = document.getElementById('upFile');
            var fileDisplayArea = document.getElementById('fileDisplayArea');
            var file = fileInput.values;
            var filePath = $('#upFile').val(); // "c:\\test.pdf";
            var file = filePath.match(/\\([^\\]+)$/)[1];

            var soapEnv =
                "<soap:Envelope xmlns:xsi='http://www.w3.org/2001/XMLSchema-instance' xmlns:xsd='http://www.w3.org/2001/XMLSchema' xmlns:soap='http://schemas.xmlsoap.org/soap/envelope/'> \
                 <soap:Body>\
                     <CopyIntoItems xmlns='http://schemas.microsoft.com/sharepoint/soap/'>\
                         <SourceUrl>" + filePath + "</SourceUrl>\
                             <DestinationUrls>\
                                 <string>https://nike.sharepoint.com/teams/ap1/gctech/DEV/Apptexfiles/" + file + "</string>\
                             </DestinationUrls>\
                             <Fields>\
                                 <FieldInformation Type='Text' DisplayName='Title' InternalName='Title' Value='Test'  />\
                                   <FieldInformation Type='Text' DisplayName='BudgetId' InternalName='BudgetId' Value='8'  />\
                             </Fields>\
                         <Stream>" + X + "</Stream>\
                     </CopyIntoItems>\
                 </soap:Body>\
             </soap:Envelope>";

            $.ajax({
                url: "https://nike.sharepoint.com/teams/ap1/gctech/DEV/_vti_bin/copy.asmx",
                beforeSend: function (xhr) { xhr.setRequestHeader("SOAPAction", "http://schemas.microsoft.com/sharepoint/soap/CopyIntoItems"); },
                type: "POST",
                dataType: "xml",
                data: soapEnv,
                complete: processResult,
                contentType: "text/xml; charset=\"utf-8\""
            });

        }
        //SP.SOD.executeOrDelayUntilScriptLoaded(initialize, 'SP.js');
        //SP.SOD.executeOrDelayUntilScriptLoaded(test, 'SP.js');

        function errorHandler(evt) {
            if (evt.target.error.name == "NotReadableError") {
                // The file could not be read.
            }
        }
        function _arrayBufferToBase64(buffer) {
            var binary = ''
            var bytes = new Uint8Array(buffer)
            var len = bytes.byteLength;
            for (var i = 0; i < len; i++) {
                binary += String.fromCharCode(bytes[i])
            }
            return window.btoa(binary);
        }
        function updateProgress(evt) {
        }
        function processResult(xData, status) {
            alert("Uploaded SuccessFully");
        }
        

四、创建Item及上传附件

//Create other item with an attachment.
function CreateOtherItem()
{
    var otherlist = curWeb.get_lists().getByTitle(otherListTitle);
    var itemCreateInfo = new SP.ListItemCreationInformation();
    var otherItem = otherlist.addItem(itemCreateInfo);

    otherItem.set_item("Title", $("#txtReqName").val().trim());

    otherItem.update();
    curContext.load(otherItem); //, 'Include(ID, Title)'
    curContext.executeQueryAsync(Function.createDelegate(this, onCreateSucceeded), Function.createDelegate(this, onCreateFailed));
    function onCreateSucceeded(sender, args) {
        var itemId = otherItem.get_item("ID");
        var rootUrl = otherItem.get_item('FileDirRef');
        var attachFolder;

        if (!otherItem.get_item('Attachments')) { //Create new folder
            var rootAttachUrl = String.format('{0}/Attachments', rootUrl); //list.get_rootFolder().get_serverRelativeUrl()
            var rootAttachFolder = curWeb.getFolderByServerRelativeUrl(rootAttachUrl);
            attachFolder = rootAttachFolder.get_folders().add("_" + itemId);
            attachFolder.moveTo(rootAttachUrl + '/' + itemId);
            curContext.load(attachFolder);
        }
        else {
            var attachFolderUrl = String.format('{0}/Attachments/{1}', rootUrl, itemId);
            attachFolder = curWeb.getFolderByServerRelativeUrl(attachFolderUrl);
            curContext.load(attachFolder);
        }
        curContext.executeQueryAsync(onSuccess, onFailure);

        function onSuccess() {
            var newFile;
            var fileCreateInfo;
            var input = document.getElementById("upApproval");
            var file = input.files[0];
            var freader = new FileReader();
            freader.onload = function (e) {
                fileCreateInfo = new SP.FileCreationInformation();
                fileCreateInfo.set_url(file.name);
                fileCreateInfo.set_overwrite(true);

                var encContent = new SP.Base64EncodedByteArray();
                var arr = convertDataURIToBinary(e.target.result);
                for (var i = 0; i < arr.length; ++i) {
                    encContent.append(arr[i]);
                }
                fileCreateInfo.set_content(encContent);

                newFile = attachFolder.get_files().add(fileCreateInfo);
                curContext.load(newFile);
                curContext.executeQueryAsync();
                alert("Success!");
            };
            freader.readAsDataURL(file);
        }
        function onFailure() {
            // Error occurred
            alert("Request failed: " + arguments[1].get_message());
            console.log("Request failed: " + arguments[1].get_message());
        }
    }
    function onCreateFailed(sender, args) {
        console.log('Request failed. ' + args.get_message() + '\n' + args.get_stackTrace());
    }
}
