标签:JQuery web SharePoint item 添加 jQuery data API
在SharePoint Framework中使用JQuery,调用SharePoint Rest API批量添加,更新item。这里使用Rest API中的Batch命令。
1, 创建项目
请参考这个微软官方文档创建SPFx项目: https://docs.microsoft.com/en-us/sharepoint/dev/spfx/web-parts/get-started/add-jqueryui-accordion-to-web-part
2, 修改UI,添加按钮和按钮事件。
public render(): void {
this.domElement.innerHTML = `
<div class="${ styles.demoCi }">
<div class="${ styles.container }">
<div class="${ styles.row }">
<div class="${ styles.column }">
<span class="${ styles.title }">Welcome to SharePoint!</span>
<p class="${ styles.subTitle }">Customize SharePoint experiences using Web Parts.</p>
<p class="${ styles.description }">${escape(this.properties.description)}</p>
<div class="${ styles.row }">
<span class="${styles.title}">Create items</span>
<button class="${styles.button}" id="createButton"><span>Create</span></button>
</div>
<div class="${ styles.row }">
<span class="${styles.title}">Update items</span>
<button class="${styles.button}" id="updateButton"><span>Update</span></button>
</div>
</div>
</div>
</div>
</div>`;
this.bindButtonEvent();
}
private bindButtonEvent() {
const webpart:DemoCiWebPart = this;
this.domElement.querySelector("#createButton").addEventListener('click', ()=> {webpart.createNewItem();});
this.domElement.querySelector("#updateButton").addEventListener('click', ()=> {webpart.updateItem();});
}
3, 解决403 digist令牌问题
首先添加一个方法,做一个简单的JQuery调用Rest API的测试:
jQuery.ajax({
url: this.context.pageContext.web.absoluteUrl + "/_api/web/lists/GetByTitle('MyTestList')",
method: "POST",
headers: {
"Accept": "application/json; odata=verbose",
"X-RequestDigest": jQuery('#__REQUESTDIGEST').val()
},
success: function (data) {},
error: function (data, errorCode, errorMessage) {}
});
启动gulp serve,在online工作台中添加并运行web part,会发现调用Rest API的时候,提示如下错误:
HTTP/1.1 403 FORBIDDEN
{"error":{"code":"-2130575252, 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."}}}
这是因为没有获取digist令牌的缘故( jQuery('#__REQUESTDIGIST').val() 返回undefined )。所以需要先使用如下代码获取令牌,然后再执行代码:
jQuery.ajax({
url: this.context.pageContext.web.absoluteUrl + "/_api/contextinfo",
method: "POST",
headers: { "Accept": "application/json; odata=verbose"},
success: function (data) {
const digist = data.d.GetContextWebInformation.FormDigestValue;
//这里使用获取到的令牌
},
error: function (data, errorCode, errorMessage) {
alert(errorMessage)
}
});
3, 批量处理添加和更新
private createNewItem() {
const webpart : DemoCiWebPart = this;
jQuery.ajax({
url: this.context.pageContext.web.absoluteUrl + "/_api/contextinfo",
method: "POST",
headers: { "Accept": "application/json; odata=verbose"},
success: function (data) {
//jQuery('#__REQUESTDIGEST').val(data.d.GetContextWebInformation.FormDigestValue);
webpart.CallAddRest(data.d.GetContextWebInformation.FormDigestValue);
},
error: function (data, errorCode, errorMessage) {
alert(errorMessage)
}
});
}
private CallAddRest(digist) {
let startDate = new Date();
console.log(startDate.getMinutes() + '-' + startDate.getSeconds() + '-' + startDate.getMilliseconds());
const batchGuid = this.generateUUID();
const changeSetId = this.generateUUID();
let batchContents = [];
for(let i=1;i<50;i++)
{
const dataItem =
{
'__metadata': {
'type': 'SP.Data.MyTestListItem'
},
Index: i,
BoolValue: true,
TestStr: 'test 1 - ' + i,
ChoiceOption: 'Starting',
HoursStr: '2',
Remarks: 'This is a test remarks - ' + i
};
let endpoint = this.context.pageContext.web.absoluteUrl + "/_api/web/lists/getByTitle('MyTest')/items";
//changeset
batchContents.push('--changeset_' + changeSetId);
batchContents.push('Content-Type: application/http');
batchContents.push('Content-Transfer-Encoding: binary');
batchContents.push('');
batchContents.push('POST ' + endpoint + ' HTTP/1.1');
batchContents.push('Content-Type: application/json;odata=verbose');
batchContents.push('');
batchContents.push(JSON.stringify(dataItem));
batchContents.push('');
}
batchContents.push('--changeset_' + changeSetId + '--');
let batchBody = batchContents.join('\r\n');
batchContents = new Array();
batchContents.push('--batch_' + batchGuid);
batchContents.push('Content-Type: multipart/mixed; boundary="changeset_' + changeSetId + '"');
batchContents.push('Content-Length: ' + batchBody.length);
batchContents.push('Content-Transfer-Encoding: binary');
batchContents.push('');
batchContents.push(batchBody);
batchContents.push('');
batchContents.push('--batch_' + batchGuid + '--');
batchBody = batchContents.join('\r\n');
console.log(batchBody);
const batchEndPoint = this.context.pageContext.web.absoluteUrl + '/_api/$batch';
const batchRequestHeader = {
'X-RequestDigest': digist,
'Content-Type': 'multipart/mixed; boundary="batch_' + batchGuid + '"'
};
jQuery.ajax({
url: batchEndPoint, //url
type: "POST",
headers: batchRequestHeader,
data: batchBody,
async: false,
success: function (result) {
console.log('Success!');
let endDate = new Date();
console.log(endDate.getMinutes() + '-' + endDate.getSeconds() + '-' + endDate.getMilliseconds());
console.log(result);
},
error: function (error) {
console.log('Error!');
console.error(error.responseText);
}
});
}
private updateItem() {
const webpart : DemoCiWebPart = this;
jQuery.ajax({
url: this.context.pageContext.web.absoluteUrl + "/_api/contextinfo",
method: "POST",
headers: { "Accept": "application/json; odata=verbose"},
success: function (data) {
//jQuery('#__REQUESTDIGEST').val(data.d.GetContextWebInformation.FormDigestValue);
webpart.CallUpdateRest(data.d.GetContextWebInformation.FormDigestValue);
},
error: function (data, errorCode, errorMessage) {
alert(errorMessage)
}
});
}
private CallUpdateRest(digist) {
console.log('inCall');
let startDate = new Date();
console.log(startDate.getMinutes() + '-' + startDate.getSeconds() + '-' + startDate.getMilliseconds());
const batchGuid = this.generateUUID();
const changeSetId = this.generateUUID();
let batchContents = [];
for(let i=1;i<51;i++)
{
const dataItem =
{
'__metadata': {
'type': 'SP.Data.MyTestListItem'
},
Index: i,
BoolValue: true,
TestStr: 'test 1 - ' + i,
ChoiceOption: 'Starting',
HoursStr: '2',
Remarks: 'This is a test remarks - ' + i
};
let endpoint = this.context.pageContext.web.absoluteUrl + "/_api/web/lists/getByTitle('MyTest')/items("+i+")";
//changeset
batchContents.push('--changeset_' + changeSetId);
batchContents.push('Content-Type: application/http');
batchContents.push('Content-Transfer-Encoding: binary');
batchContents.push('');
batchContents.push('PATCH ' + endpoint + ' HTTP/1.1');
batchContents.push('Content-Type: application/json;odata=verbose');
batchContents.push('Accept: application/json;odata=verbose');
batchContents.push('If-Match: *');
batchContents.push('');
batchContents.push(JSON.stringify(dataItem));
batchContents.push('');
}
batchContents.push('--changeset_' + changeSetId + '--');
let batchBody = batchContents.join('\r\n');
batchContents = new Array();
batchContents.push('--batch_' + batchGuid);
batchContents.push('Content-Type: multipart/mixed; boundary="changeset_' + changeSetId + '"');
batchContents.push('Content-Length: ' + batchBody.length);
batchContents.push('Content-Transfer-Encoding: binary');
batchContents.push('');
batchContents.push(batchBody);
batchContents.push('');
batchContents.push('--batch_' + batchGuid + '--');
batchBody = batchContents.join('\r\n');
console.log(batchBody);
const batchEndPoint = this.context.pageContext.web.absoluteUrl + '/_api/$batch';
const batchRequestHeader = {
'X-RequestDigest': digist,
'Content-Type': 'multipart/mixed; boundary="batch_' + batchGuid + '"'
};
console.log('digist: ' + digist);
jQuery.ajax({
url: batchEndPoint,
type: "POST",
headers: batchRequestHeader,
data: batchBody,
async: false,
success: function (result) {
console.log('Success!');
let endDate = new Date();
console.log(endDate.getMinutes() + '-' + endDate.getSeconds() + '-' + endDate.getMilliseconds());
console.log(result);
},
error: function (error) {
console.log('Error!');
console.error(error.responseText);
}
});
}
private generateUUID() {
var d = new Date().getTime();
var uuid = 'xxxxxxxx-xxxx-4xxx-yxxx-xxxxxxxxxxxx'.replace(/[xy]/g, function (c) {
var r = (d + Math.random() * 16) % 16 | 0;
d = Math.floor(d / 16);
return (c == 'x' ? r : (r & 0x7 | 0x8)).toString(16);
});
return uuid;
};
简单测评:
50 条数据 | 100条数据 | 200条数据 | |
添加 | 10 秒左右 | 20 秒左右 | 30 秒左右 |
更新 | 3 秒左右 | 4 秒左右 | 11 秒左右 |
测试使用的表有6个列,每次添加和更新都是操作6个列。由此可见批量添加是非常耗时的,批量更新随着数据量变大,耗时会增加很快。如果批量更新200条数据,最好按批次更新,每次更新100条数据,会更省时间。
实际上使用JQuery调用Rest API是一种通用的方式,不局限于SharePoint Framework项目中。
在SharePoint Framework里,可以更方便地使用SPHttpClientBatch对象来实现上面的功能。请参见另一篇博客:在SharePoint Framework中使用SPHttpClientBatch对象批量添加,更新item
