从 Web api 每页只获得 20 个第一个结果是可能的吗？

Question

我正在学习如何在 React 中使用 ag-grid，我发现了一个问题：

当我从网络获取数据时 api 结果非常好，比如 8600 个结果

问题:

我想知道是否有可能，例如，每页只获得 20 个结果而不是一次获得所有结果，或者仅从具有这种洞察力的 api 准备的

一些代码：

//http request

onGridReady = params => {
  this.gridApi = params.api;
  this.gridColumnApi = params.columnApi;

  const httpRequest = new XMLHttpRequest();

  httpRequest.open( "GET", "https://raw.githubusercontent.com/ag-grid/ag-grid/master/packages/ag-grid-docs/src/olympicWinners.json" );
  httpRequest.send();
  httpRequest.onreadystatechange = () => {
    if (httpRequest.readyState === 4 && httpRequest.status === 200) {
      updateData(JSON.parse(httpRequest.responseText));
    }
  };
  
  const updateData = data => {
    this.setState({ rowData: data });
  };
};


//ag grid

render() {
  return (
      <div className="ag-theme-balham" style={{ height: '700px', width: '95%' }}>

        <AgGridReact
          columnDefs={this.state.columnDefs}
          defaultColDef={this.state.defaultColDef}
          defaultColGroupDef={this.state.defaultColGroupDef}
          columnTypes={this.state.columnTypes}
          rowData={this.state.rowData}
          onGridReady={this.onGridReady}
          pagination={true}          
          paginationPageSize={20}
        />
      </div>
  );
}

根据HMR评论回答我的问题：

The answer is no because you are requesting a json file, not a json endpoint.

If you are requesting an endpoint then you can (for example) add parameters such as page=.. and size=..

It's possible to get just 20 first results per page from web api?
