Ajax basic operations, and interfaces can be set across domains

  var obj = {
            BaseId: OrgID,
            Title: title,
            AccountCategoryId: AccountCategoryId,
            UserId: UserId,
            Content: Content,
            Status: Status,
            AboutExtType: AboutExtType,

            ImgList: ImgList,
            contentList: contentList,

            Picture: Picture,
            vid: vid,
        };


$.ajax({
            type: 'post',
            url: url1,
            data: obj,
            headers: {
                'Authorization': Authorization
            },//头部参数，需要在接口项目中设置，头部可传参数名Authorization
            async: false,//默认异步，true
            success: function (res) {
                if (res.code == '10000') {
                    top.layer.msg('操作成功', { icon: 1, time: 2000 });
                    $('#add').removeClass('layui-btn-disabled');
                    var index = parent.layer.getFrameIndex(window.name);
                    parent.layer.close(index);//关闭当前页
                }
                else {
                    top.layer.msg('操作失败', { icon: 2, time: 2000 });
                    $('#add').removeClass('layui-btn-disabled');
                }
            }
        })

The interface is called in js, and the interface project needs to set cross-domain and request header parameters. Set the code in the Web.config of the interface project

<system.webServer>
    <validation validateIntegratedModeConfiguration="false" />
    <httpProtocol>
      <customHeaders>
        <!--*代表任何人域名都可以访问，也可以可以指定那些域名可以访问，指定多个可以用“，”隔开-->
        <add name="Access-Control-Allow-Origin" value="*" />
        <add name="Access-Control-Allow-Headers" value="AuthToken, Authorization, Origin, Content-Type, Accept, X-Requested-With" />
        <add name="Access-Control-Allow-Methods" value="GET, PATCH, POST, PUT, DELETE, OPTIONS" />
      </customHeaders>
    </httpProtocol>
    <!--<handlers>  跨域时不需要加此数据，加了之后无法传递 handler
      <remove name="ExtensionlessUrlHandler-Integrated-4.0" />
      <remove name="OPTIONSVerbHandler" />
      <remove name="TRACEVerbHandler" />
      <add name="ExtensionlessUrlHandler-Integrated-4.0" path="*." verb="*" type="System.Web.Handlers.TransferRequestHandler" preCondition="integratedMode,runtimeVersionv4.0" />
    </handlers>-->
