重命名 Laravel 集合键

如何解决重命名 Laravel 集合键

我有一套数据字典$dataDictCollection

"column_a" => "Column A","column_b" => "Column B","column_c" => "Column C","column_d" => "Column D","column_e" => "Column E",

我有另一组结果$resultCollection

[{
    "column_a" => "value 100","column_b" => "value 200","column_c" => "value 300","column_d" => "value 400","column_e" => "value 500",},{
    "column_a" => "value 110","column_b" => "value 220","column_c" => "value 330","column_d" => "value 440","column_e" => "value 550",}]

在结果中，我希望将数据字典的值作为结果的键。例如：

"Column A" => "value 100","Column B" => "value 200","Column C" => "value 300","Column D" => "value 400","Column E" => "value 500",

请注意，我的列数很多，我无法指定如下所示的键名。

return $data['Column A'] = 'value 100';

我尝试了 mapWithKeys、keyBy，但我不知道如何返回我想要的结果。

我试过了

return collect($resultCollection)->map(function ($result) use ($dataDictCollection) {
    return collect($dataDictCollection)->map(function ($dataDic) use ($result) {
        $name[$dataDic] = $result[$dataDic];
        return $name;
    });
});

但它返回这个:(

"column_a": {
    "Column A": "value 100"
},"column_b": {
    "Column B": "value 200"
},

又一次尝试

return collect($resultCollection)->map(function ($result) use ($dataDictCollection) {
    return collect($result)->combine($dataDictCollection);
})->values();

但它像这样返回，相反并且不返回完整的数据字典。

[{
    "value 100" => "Column A","value 200" => "Column B","value 300" => "Column C",{
    "value 110" => "Column A","value 220" => "Column B","value 330" => "Column C",}]    

解决方法

您可以使用combine收集方法

public interface IBotClient
{
    /// <summary>
    /// Gets account balance for an asset.
    /// </summary>
    /// <param name="asset">The asset.</param>
    /// <param name="ct">Cancellation token.</param>
    /// <returns>The account balance.</returns>
    /// <exception cref="T:ElonMuskBot.Core.Exceptions.CallFailedException">If the call fails.</exception>
    Task<Balance> GetBalanceAsync(string asset,CancellationToken ct = default);

    /// <summary>
    /// Gets account balances.
    /// </summary>
    /// <param name="ct">Cancellation token.</param>
    /// <returns>The account balances.</returns>
    /// <exception cref="T:ElonMuskBot.Core.Exceptions.CallFailedException">If the call fails.</exception>
    Task<IList<Balance>> GetBalancesAsync(CancellationToken ct = default);

    ...
}

public abstract class BotClientBase : IBotClient
{
    private readonly IBinanceClient _client;
    private readonly IBinanceSocketClient _socketClient;

    protected BotClientBase(IBinanceClient client,IBinanceSocketClient socketClient)
    {
        _client = client;
        _socketClient = socketClient;
    }

    /// <summary>
    /// Gets account balance for an asset.
    /// </summary>
    /// <param name="asset">The asset.</param>
    /// <param name="ct">Cancellation token.</param>
    /// <returns>The account balance.</returns>
    /// <exception cref="T:ElonMuskBot.Core.Exceptions.CallFailedException">If the call fails.</exception>
    public abstract Task<Balance> GetBalanceAsync(string asset,CancellationToken ct = default);

    /// <summary>

    public abstract Task<IList<Balance>> GetBalancesAsync(CancellationToken ct = default);

    ...
}

public class SpotBotClient : BotClientBase
{
    private readonly ILogger<SpotBotClient> _logger;
    private readonly IBinanceClient _client;
    private readonly IBinanceSocketClient _socketClient;

    public SpotBotClient(ILogger<SpotBotClient> logger,IBinanceClient client,IBinanceSocketClient socketClient) : base(client,socketClient)
    {
        _logger = logger ?? throw new ArgumentNullException(nameof(logger));
        _client = client;
        _socketClient = socketClient;
    }

    public override async Task<Balance> GetBalanceAsync(string asset,CancellationToken ct = default)
    {
        ...
    }
