Question

我正在通过eBay API响应解析。我想将其返回给网站更整洁，并更易于使用JavaScript解析。我成功地通过XML进行了解析...但是现在将其转换为JSON以重新发送回客户端让我有些头疼。

注意：$resp是eBay的回复。它们的全长XML已成功与下面的代码一起解析。

例如 ... $valueName可能是Grade。然后，我进入下一个foreach循环并获取该值。这些values可能是10, 9.5, 9 etc 。

这是我的PHP代码。

$arrayName = array();
$arrayValue = array();

foreach($resp->aspectHistogramContainer->aspect as $name) {
    $nameAspect = $name['name'];
    //$arrayName["aspectName"] = $nameAspect;

    foreach($name->valueHistogram as $value) {
        $valueAspect = $value['valueName'];
        //$arrayValue["aspectValue"] = $valueAspect;    
    }

    //array_push($arrayName, $arrayValue);
}
echo json_encode($arrayName);

因此，无需我尝试创建自己的JSON，我就能获得所需的东西。我回应了结果，它与此相似...

NAME

-----值

-----值

-----值

NAME

-----值

NAME

等等等

对于JSON响应...我正在寻找类似的东西...

[
  {
        "name": "NAME",
        "value": ["value", "value"]
    }, {
        "name": "name",
        "value": ["value", "value"]
    }
]

任何帮助和指导将不胜感激。

eBay的响应是这样的（还有更多<aspect>和<valueHistogram>）

<getHistogramsResponse xmlns="http://www.ebay.com/marketplace/search/v1/services">
<ack>Success</ack>
<version>1.13.0</version>
<timestamp>2018-11-07T15:32:20.380Z</timestamp>
<aspectHistogramContainer>
<domainDisplayName>Baseball Cards</domainDisplayName>
<aspect name="Card Manufacturer">
<valueHistogram valueName="Ace Authentic">
<count>19</count>
</valueHistogram>
<valueHistogram valueName="American Caramel">
<count>2024</count>
</valueHistogram>
<valueHistogram valueName="APBA">
<count>10554</count>
</valueHistogram>
<valueHistogram valueName="Bazooka">
<count>8826</count>
</valueHistogram>
<valueHistogram valueName="Be A Player">
<count>17</count>
</valueHistogram>
<valueHistogram valueName="Bell Brand Dodgers">
<count>334</count>

要对其进行编码（并假设为SimpleXML），这只是构建每个内部$aspect数据数组，然后将值添加到其中的一种情况。我使用(string)来确保数据没有存储为SimpleXMLElement，这可能会导致副作用...

$arrayName = array();

foreach($resp->aspectHistogramContainer->aspect as $name) {
    $aspect = [ "name" => (string)$name['name']];

    foreach($name->valueHistogram as $value) {
        $aspect["value"][] = (string)$value['valueName'];
    }
    $arrayName[] = $aspect;
}
echo json_encode($arrayName);

使用示例XML，这给出了...

[{"name":"Card Manufacturer","value":["Ace Authentic","American Caramel","APBA","Bazooka","Be A Player","Bell Brand Dodgers"]}]

创建一个单个数组$resultArray并将值存储在其中。通过以最小的更改维护当前代码结构，这是更新的代码段，

$resultArray = array();

$i = 0; // Maintain Array Index value
foreach($resp->aspectHistogramContainer->aspect as $name) {
    $resultArray[$i]["aspectName"] = (string)$name['name'];;

    foreach($name->valueHistogram as $value) {
        $resultArray[$i]["aspectValue"][] = (string)$value['valueName'];
    }
    $i++; // Increment array index to store next value
}
echo json_encode($resultArray);

Answer 3

$results = array();

// Parse the XML into a keyed array

foreach($resp->aspectHistogramContainer->aspect as $name) {
    $nameAspect = (string) $name['name'];
    $values = array();
    foreach($name->valueHistogram as $value) {
        $values[] = (string) $value['valueName'];
    }
    $results[$nameAspect] = $values;
}

// This keeps things simple - rewrite to the required JSON format

$outputForJSON = array();
foreach ($results as $name => $values) {
    $outputForJSON[] = array(
         "name" => $name,
         "values" => $values
    );
}

echo json_encode($outputForJSON);

从解析的XML PHP创建JSON响应
