如何解决带有ajax的jQuery数据表，发布API调用挂钩 我的问题是-更新1：

我正在通过服务器端分页实现jquery DataTable。请参考下面的代码段-

脚本

$(async function() {
    $('#registry_table').DataTable({
        serverSide: true,ajax: {
            url: 'localhost:3000/provenance/registries',headers: {
                'Content-Type': 'application/json','Authorization': 'Bearer ' + localStorage.getItem("token")
            },data: () => {
               return {page: 0,per_page: 5};
            }
        },columns: [
            {data: 'name',defaultContent: 'N/A'},{data: 'created',{data: 'extrinsic',{data: 'registry',defaultContent: ' <span class="text-primary bg-white fa-border d-inline-block" style="cursor: pointer" title="Rename Registry"><i class="fas fa-pen-nib"/> Rename</span>'}
        ],language: {
            searchPlaceholder: "Search...",search: "",lengthMenu: "_MENU_ &nbsp;items/page"
        }
    });
});

HTML

<table class="table table-striped mg-b-0" id="registry_table">
    <thead>
        <tr>
            <th class="text-left">#</th>
            <th class="text-left">Name</th>
            <th class="text-left">Created on</th>
            <th class="text-left">Transaction</th>
            <th class="text-center">Action</th>
        </tr>
    </thead>
</table>

API响应

{
  "registries": [
    {
      "registry": 489607958,"created_by": "5DqdTHZLA8X2Lk2FqCPFM9kxd8GmdMbyboFiFg6gmB8sHCg4","name": "test 7","created": "2020-09-14T15:08:49.006766"
    },{
      "registry": 1421927575,"name": "test 6","created": "2020-09-14T15:08:43.104835"
    },{
      "registry": 1560576458,"name": "test 4","created": "2020-09-14T15:08:34.132407"
    },{
      "registry": 1766285412,"name": "test 5","created": "2020-09-14T15:08:27.376323"
    },{
      "registry": 155398053,"name": "test 3","created": "2020-09-14T15:08:16.768747"
    }
  ],"total": 7
}

如果总行数为 7 并且per_page = 5 ，则它应显示 2 页。但是在浏览器中，它显示5页。另外，页面信息显示错误信息。

浏览器

我的问题是-

1. 获取数据后是否可以设置页数/总项数
2. 页面信息应为Showing 1 to 5 of 7 entries (filtered from 7 total entries)，如何正确设置这些信息？
3. 如何将整行作为参数传递给函数（重命名按钮）

注意：API尚在生产中，不可能更改。

更新1：

脚本（已修改 data ，并在Ajax部分添加了 dataSrc

data: (d) => {
    d.page =self.page;
    d.per_page =self.per_page;
    delete d.columns;
    delete d.order;
    delete d.search;
    delete d.start;
    delete d.length;
},dataSrc: (response) => {
    response.draw = 1;
    response.recordsTotal = response.total;
    response.recordsFiltered = response.registries.length;
    response.data = response.registries;

    return response.data;
}

现在它不显示任何数据，但是其他一切都很好。
