CSOM：服务器不允许将邮件大于 2097152 字节

在sharepoint csom, js调用中，功能需求是将图片转换为字节，存在sharepoint list中。当提交的内容大于1M左右时，就会提示"Original error: Microsoft.SharePoint.Client.InvalidClientQueryException: 请求消息太大。服务器不允许大于 2097152 字节的消息"。

解决方案：在应用服务器上，powshell进行配置就行。

$ws = [Microsoft.SharePoint.Administration.SPWebService]::ContentService $ws.ClientRequestServiceSettings.MaxReceivedMessageSize = 209715200 $ws.ClientRequestServiceSettings.MaxParseMessageSize = 209715200 $ws.Update() 

 function updateListItem(title, logo, webID, summary, themeBackground) {  2         var clientContext = new SP.ClientContext();  3         var oList = clientContext.get_web().get_lists().getByTitle('SiteInfo');  4         var ID= $("#siteInfoItemID").val();  5         this.oListItem = oList.getItemById(ID);  6         oListItem.set_item('Title', title);  7         oListItem.set_item('ThemeLogo', logo);  8         oListItem.set_item('Summary', summary);  9         oListItem.set_item('ThemeBackground', themeBackground); 10         
 oListItem.update(); 12  clientContext.executeQueryAsync( 13             Function.createDelegate(this, this.onQuerySucceeded), 14             Function.createDelegate(this, this.onQueryFailed) 15  ); 16     }
