Question

我想更改数组的结构以生成稍微不同的JSON文件。我尝试将import UIKit enum Section: Int { case toDo case done } class ItemListDataProvider: NSObject, UITableViewDataSource, UITableViewDelegate { var itemManager: ItemManager? func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int { guard let itemManager = itemManager else{return 0} guard let itemSection = Section(rawValue: section)else{ fatalError() } let numberOfRows: Int switch itemSection { case .toDo: numberOfRows = itemManager.toDoCount case .done: numberOfRows = itemManager.doneCount } return numberOfRows } func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell { let cell = tableView.dequeueReusableCell(withIdentifier: "ItemCell", for: indexPath) as! ItemCell guard let itemManager = itemManager else { fatalError() } guard let section = Section(rawValue: indexPath.section) else { fatalError() } let item: ToDoItem switch section { case .toDo: item = itemManager.item(at: indexPath.row) case .done: item = itemManager.doneItem(at: indexPath.row) } cell.configCell(with: item) return cell } func numberOfSections(in tableView: UITableView) -> Int { return 2 } }放入额外的数组中，但它不起作用。

在JSON 'category'中应该是aditional []：

'category'

而不是：

"categories": [{
        "category": [{
            "label": "N.12\/02"
        }, {
            "label": "Pn.13\/02"
        }, {
            "label": "Wt.14\/02"
        }, {
            "label": "\u015ar.15\/02"
        }, {
            "label": "Cz.16\/02"
        }, {
            "label": "Pt.17\/02"
        }, {
            "label": "So.18\/02"
        }]
    }],

我使用此代码创建数组而不是JSON：

"categories": {
        "category": [{
            "label": "N.12\/02"
        }, {
            "label": "Pn.13\/02"
        }, {
            "label": "Wt.14\/02"
        }, {
            "label": "\u015ar.15\/02"
        }, {
            "label": "Cz.16\/02"
        }, {
            "label": "Pt.17\/02"
        }, {
            "label": "So.18\/02"
        }]
    },

此刻我有这个输出：

$arrData = array(
    "chart" => array(
        "caption" => "Number of visitors last week",
        "subCaption" => "Bakersfield Central vs Los Angeles Topanga",
        "captionFontSize" => "14",
        "subcaptionFontSize" => "14",
        "subcaptionFontBold" => "0",
        "paletteColors" => "#0075c2,#1aaf5d,#FF5733,#33B5FF",
        "bgcolor" => "#ffffff",
        "showBorder" => "0",
        "showShadow" => "0",
        "showCanvasBorder" => "0",
        "usePlotGradientColor" => "0",
        "legendBorderAlpha" => "0",
        "legendShadow" => "0",
        "showAxisLines" => "0",
        "showAlternateHGridColor" => "0",
        "divlineThickness" => "1",
        "divLineDashed" => "1",
        "divLineDashLen" => "1",
        "xAxisName" => "Day",
        "showValues" => "0"
    )
);

$actualCategory = array( $rowData[0][1], $rowData[0][2], $rowData[0][3], $rowData[0][4], $rowData[0][5], $rowData[0][6], $rowData[0][7]);
$a = array(
    array( $rowData[2][1], $rowData[2][2], $rowData[2][3], $rowData[2][4], $rowData[2][5], $rowData[2][6], $rowData[2][7]),
    array( $rowData[5][1], $rowData[5][2], $rowData[5][3], $rowData[5][4], $rowData[5][5], $rowData[5][6], $rowData[5][7]),
    array( $rowData[8][1], $rowData[8][2], $rowData[8][3], $rowData[8][4], $rowData[8][5], $rowData[8][6], $rowData[8][7]),
    array( $rowData[11][1], $rowData[11][2], $rowData[11][3], $rowData[11][4], $rowData[11][5], $rowData[11][6], $rowData[11][7])
);


$arrData['categories'] = array( 'category' => array());
foreach ($actualCategory as $value) {
    array_push($arrData['categories']['category'],
        array(
            'label' => $value
        )
    );
}

$arrData['dataset'] = array();

$q = 1;
for($z = 0;$z <= 3; $z++){

    $x[$z] = array('seriesname' => $rowData[$q][0], 'data' => array());
    foreach ($a[$z] as $value) {
        array_push($x[$z]['data'],
            array(
                'value' => $value
            )
        );
    }
    $q = $q + 3;
}
$arrData['dataset'] = $x;
$jsonEncodedData = json_encode($arrData);

我需要的JSON文件：

{"chart":{"caption":"Number of visitors last week","subCaption":"Bakersfield Central vs Los Angeles Topanga","captionFontSize":"14","subcaptionFontSize":"14","subcaptionFontBold":"0","paletteColors":"#0075c2,#1aaf5d,#FF5733,#33B5FF","bgcolor":"#ffffff","showBorder":"0","showShadow":"0","showCanvasBorder":"0","usePlotGradientColor":"0","legendBorderAlpha":"0","legendShadow":"0","showAxisLines":"0","showAlternateHGridColor":"0","divlineThickness":"1","divLineDashed":"1","divLineDashLen":"1","xAxisName":"Day","showValues":"0"},"categories":{"category":[{"label":"N.12\/02"},{"label":"Pn.13\/02"},{"label":"Wt.14\/02"},{"label":"\u015ar.15\/02"},{"label":"Cz.16\/02"},{"label":"Pt.17\/02"},{"label":"So.18\/02"}]},"dataset":[{"seriesname":"IRDN","data":[{"value":"142.59"},{"value":"174.88"},{"value":"176.97"},{"value":"182.48"},{"value":"160.15"},{"value":"160.72"},{"value":"165.47"}]},{"seriesname":"SIRDN","data":[{"value":"148.81"},{"value":"197.29"},{"value":"202.27"},{"value":"211.93"},{"value":"177.87"},{"value":"179.37"},{"value":"177.69"}]},{"seriesname":"IRDN24","data":[{"value":"140.31"},{"value":"174.50"},{"value":"180.38"},{"value":"187.70"},{"value":"161.91"},{"value":"161.62"},{"value":"160.98"}]},{"seriesname":"IRDN 8.22","data":[{"value":"147.33"},{"value":"197.02"},{"value":"202.21"},{"value":"211.28"},{"value":"178.11"},{"value":"179.32"},{"value":"176.31"}]}]}

我的阵列转储：

{"chart":{"caption":"Number of visitors last week","subCaption":"Bakersfield Central vs Los Angeles Topanga","captionFontSize":"14","subcaptionFontSize":"14","subcaptionFontBold":"0","paletteColors":"#0075c2,#1aaf5d,#FF5733,#33B5FF","bgcolor":"#ffffff","showBorder":"0","showShadow":"0","showCanvasBorder":"0","usePlotGradientColor":"0","legendBorderAlpha":"0","legendShadow":"0","showAxisLines":"0","showAlternateHGridColor":"0","divlineThickness":"1","divLineDashed":"1","divLineDashLen":"1","xAxisName":"Day","showValues":"0"},"categories":[{"category":[{"label":"N.12\/02"},{"label":"Pn.13\/02"},{"label":"Wt.14\/02"},{"label":"\u015ar.15\/02"},{"label":"Cz.16\/02"},{"label":"Pt.17\/02"},{"label":"So.18\/02"}]}],"dataset":[{"seriesname":"IRDN","data":[{"value":"142.59"},{"value":"174.88"},{"value":"176.97"},{"value":"182.48"},{"value":"160.15"},{"value":"160.72"},{"value":"165.47"}]},{"seriesname":"SIRDN","data":[{"value":"148.81"},{"value":"197.29"},{"value":"202.27"},{"value":"211.93"},{"value":"177.87"},{"value":"179.37"},{"value":"177.69"}]},{"seriesname":"IRDN24","data":[{"value":"140.31"},{"value":"174.50"},{"value":"180.38"},{"value":"187.70"},{"value":"161.91"},{"value":"161.62"},{"value":"160.98"}]},{"seriesname":"IRDN 8.22","data":[{"value":"147.33"},{"value":"197.02"},{"value":"202.21"},{"value":"211.28"},{"value":"178.11"},{"value":"179.32"},{"value":"176.31"}]}]}

我的问题是如何更改我的代码呢？

Answer 1

你应该使用

$arrData['categories'] = array( array ('category' => array()));

而不是

$arrData['categories'] = array( 'category' => array());

它将按您的意愿运作。

更改数组的结构以创建JSON
