如何使用SharePoint_API进行更新/合并/补丁到SharePoint列表

Question

我想对SharePoint列表进行更新。我阅读的标题必须包括"X-HTTP-Method": "MERGE"，并且类型应为POST。我不知道是否要求"IF-MATCH": "*"具有ETAG。当我删除项目时，"IF-MATCH": "*"不需要具有ETAG。这是我的代码：

function UpdateBooking(ajaxData) {
  var url = `${_spPageContextInfo.webAbsoluteUrl}/_api/web/lists/getbytitle('Bokningar')/items`;
  //requestHeaders
  var requestHeaders = {
    "accept": "application/json;odata=verbose",
    "content-type": "application/json;odata=verbose",
    "X-HTTP-Method": "MERGE",
    "IF-MATCH": "*",
    "X-RequestDigest": jQuery('#__REQUESTDIGEST').val()
  }
  //Data
  var data = {
    __metadata: {
      "type": "SP.Data.BokningarListItem"
    },
    Title: ajaxData.Title,
    EventDate: ajaxData.EventDate,
    EndDate: ajaxData.EndDate,
    Description: ajaxData.Description,
    IsBlock: ajaxData.IsBlock,
    Milj_x00f6_: ajaxData.Milj_x00f6_,
    Program: ajaxData.Program
  };
  //requestBod
  var requestBody = JSON.stringify(data);
  //Post
  var post = jQuery.ajax({
    url: url,
    type: "POST",
    headers: requestHeaders,
    data: requestBody
  });
  //Done
  post.done(function(data, textStatus, jqXHR) {});
  //Fail
  post.fail(function(jqXHR, textStatus, errorThrown) {});
}

这是我遇到的错误：

{"error":{"code":"-1, Microsoft.SharePoint.Client.InvalidClientQueryException","message":{"lang":"en-US","value":"The type SP.ListItemEntityCollection does not support HTTP PATCH method."}}}

有什么想法我做错了什么？

Answer 1

解决了它。我没有在URL中提供ID。

    var url = `${_spPageContextInfo.webAbsoluteUrl}/_api/web/lists/getbytitle('Bokningar')/items('${id}')`;
