我试图通过REST API发布有关SharePoint在线讨论板的特定讨论的回复,但无法执行此操作。我不想使用SP.utilities,因为这个REST API将从Android App调用。
以下是我正在实施的代码:
$.ajax({
url:"../_api/web/Lists/getbytitle(listname)/items?$filter=ParentItemID eq 40",
type: "POST",
contentType: "application/json;odata=verbose",
data: JSON.stringify(itemProperties),
headers: {
"Accept": "application/json;odata=verbose",
"X-RequestDigest": $("#__REQUESTDIGEST").val(),
"IF-MATCH": "*"
},
success: function (data) {
alert("Successfully posted!!");
},
error: function (error) {
alert("error");
console.log(JSON.stringify(error));
}
});
它不是在讨论中创建回复,而是创建一个新的讨论项目。 任何帮助将受到高度赞赏。
答案 0 :(得分:1)
要在讨论区中创建消息项(回复),需要指定以下属性:
FileSystemObjectType
,消息项目需要设置为0 ContentTypeId
- 邮件项目的内容类型ID ParentItemID
- 讨论项目(消息容器)id 关于ParentItemID
属性
ParentItemID
属性,因为它是只读属性,这意味着以下用于创建消息项的查询失败:
Url /_api/web/lists/getbytitle('Discussions')/items
Method POST
Data {
'__metadata': { "type": "SP.Data.DiscussionsListItem" },
'Body': "Message text goes here",
'FileSystemObjectType': 0,
'ContentTypeId': '<MessageContentTypeId>',
'ParentItemID': <DiscussionItemId>
}

以下示例演示如何通过SharePoint REST API在讨论板中创建消息(回复)。
用于在讨论项目(文件夹)下创建消息以下内容 使用方法:一旦创建了消息项,它就会被移动 在讨论项目下
var listTitle = "Discussions"; //Discussions Board title
var webUrl = _spPageContextInfo.webAbsoluteUrl;
var messagePayload = {
'__metadata': { "type": "SP.Data.DiscussionsListItem" }, //set DiscussionBoard entity type name
'Body': "Message text goes here", //message Body
'FileSystemObjectType': 0, //set to 0 to make sure Message Item is created
'ContentTypeId': '0x0107008822E9328717EB48B3B665EE2266388E', //set Message content type
'ParentItemID': 123 //set Discussion item (topic) Id
};
createNewDiscussionReply(webUrl,listTitle,messagePayload)
.done(function(item)
{
console.log('Message(reply) has been sent');
})
.fail(function(error){
console.log(JSON.stringify(error));
});
,其中
function executeJson(options)
{
var headers = options.headers || {};
var method = options.method || "GET";
headers["Accept"] = "application/json;odata=verbose";
if(options.method == "POST") {
headers["X-RequestDigest"] = $("#__REQUESTDIGEST").val();
}
var ajaxOptions =
{
url: options.url,
type: method,
contentType: "application/json;odata=verbose",
headers: headers
};
if("data" in options) {
ajaxOptions.data = JSON.stringify(options.data);
}
return $.ajax(ajaxOptions);
}
function createListItem(webUrl,listTitle,payload){
var url = webUrl + "/_api/web/lists/getbytitle('" + listTitle + "')/items";
return executeJson({
"url" :url,
"method": 'POST',
"data": payload
});
}
function moveListItem(webUrl,listTitle,itemId,folderUrl){
var url = webUrl + "/_api/web/lists/getbytitle('" + listTitle + "')/getItemById(" + itemId + ")?$select=FileDirRef,FileRef";
return executeJson({
"url" :url
})
.then(function(result){
var fileUrl = result.d.FileRef;
var fileDirRef = result.d.FileDirRef;
var moveFileUrl = fileUrl.replace(fileDirRef,folderUrl);
var url = webUrl + "/_api/web/getfilebyserverrelativeurl('" + fileUrl + "')/moveto(newurl='" + moveFileUrl + "',flags=1)";
return executeJson({
"url" :url,
"method": 'POST'
});
});
}
function getParentTopic(webUrl,listTitle,itemId){
var url = webUrl + "/_api/web/lists/getbytitle('" + listTitle + "')/getItemById(" + itemId + ")/Folder";
return executeJson({
"url" :url,
});
}
function createNewDiscussionReply(webUrl,listTitle, messagePayload){
var topicUrl = null;
return getParentTopic(webUrl,listTitle,messagePayload.ParentItemID)
.then(function(result){
topicUrl = result.d.ServerRelativeUrl;
return createListItem(webUrl,listTitle,messagePayload);
})
.then(function(result){
var itemId = result.d.Id;
return moveListItem(webUrl,listTitle,itemId,topicUrl);
});
}
