如何从Rest API使用Antd Table组件呈现DataGrid

Question

I have the following code which renders a table with antd component. I created a fetchdata that is returning some information correctly

Code:

import React, { Component } from 'react';
import {  Table} from 'antd';
import { adalApiFetch } from '../../adalConfig';


class ListTenants extends Component {

    constructor(props) {
        super(props);
        this.state = {
            data: []
        };
    }

    fetchData = () => {
        adalApiFetch(fetch, "/Tenant", {})
          .then(response => response.json())
          .then(responseJson => {
            if (!this.isCancelled) {
              this.setState({ data: responseJson });
            }
          })
          .catch(error => {
            console.error(error);
          });
      };


    componentDidMount(){
        this.fetchData();
    }

    render() {
        const columns = [{
            title: 'Tenant Id',
            dataIndex: 'TenantId',
            key: 'TenantId'
          }, {
            title: 'Tenant Url',
            dataIndex: 'TenantUrl',
            key: 'TenantUrl',
        }];

        const data = [{
            TenantId: '1',
            TenantUrl: 'John Brown'           
          }, {
            TenantId: '2',
            TenantUrl: 'Jim Green'
          }, {
            TenantId: '3',
            TenantUrl: 'Joe Black'
        }];

        return (
            <Table columns={columns} dataSource={data} />
        );
    }
}

export default ListTenants;

How do I convert the json received to columns and data?

Assuming your question is how to render the object to match the keys in your Table data object, something like this should work:

repl here: https://repl.it/repls/FabulousWiryLicensing

This will give you the idea, but the cleaner solution is to map the responseJson object you're getting back from the API call and setState with that.

```

 class App extends Component {
  constructor (props) {
    super (props)
    this.state = {
      returnedData: [{
        ClientId: '1',
        Id: 'abc',
        TenantDomainUrl: 'https://example.com'
      }, {
        ClientId: '2',
        Id: 'abc',
        TenantDomainUrl: 'https:example2.com'
      }]
    }
  }
  render() {
    const { returnedData } = this.state;

    const data = returnedData.map(row => ({
      TenantId: row.Id,
      TenantUrl: row.TenantDomainUrl
    }))

    const columns = [{
        title: 'Tenant Id',
        dataIndex: 'TenantId',
        key: 'TenantId'
      }, {
        title: 'Tenant Url',
        dataIndex: 'TenantUrl',
        key: 'TenantUrl',
    }];

    return (
      <div>
        <h1>test</h1>
        <Table columns={columns} dataSource={data} />
      </div>
    );
  }
}

```
