Brandwatch php 的 HTTP API 请求答案

【问题描述】：

通过 API 请求，在 JSOn 中获取服务器响应，就像这样在一个字符串中：

{"resultsTotal":3,"resultsPage":-1,"resultsPageSize":-1,"results":[{"id":1998425622,"name":"Regionale Mentions_Branche","type":"search string","creationDate":"2015-08-21T15:13:58.226+0000","lastModificationDate":"2015-08-21T15:13:58.226+0000","lastModifiedUsername":"mueller@cybay.de","lockedQuery":false,"lockedByUsername":null},{"id":1998422533,"name":"HTP_Sponsoring","type":"search string","creationDate":"2015-08-18T08:53:38.136+0000","lastModificationDate":"2015-08-18T08:53:38.136+0000","lastModifiedUsername":"mueller@cybay.de","lockedQuery":false,"lockedByUsername":null},{"id":1998422529,"name":"HTP_Brand Mentions","type":"search string","creationDate":"2015-08-18T08:41:32.699+0000","lastModificationDate":"2015-08-18T14:42:19.977+0000","lastModifiedUsername":"mueller@cybay.de","lockedQuery":false,"lockedByUsername":null}]}

所以我使用 json_decode 来获取一个数组。

现在我想解析数组，因为我只需要 "id":xxxxxxxx 和 "name" 我的代码是：

$webservice = 'http://newapi.brandwatch.com/projects/';
$kundenId = $_POST["kunden"];
$key = "?access_token=XXXXXXXXX";
$onlySdate = $_POST["startdate"];
$onlyEdate = $_POST["enddate"];
$startdate = "&startDate=".$onlySdate ;
$enddate = "?endDate=" .$onlyEdate ;
$url = $webservice . $kundenId . "/queries/summary".$key;

$domainRequest = $url;
//header("Location:$domainRequest");
$data = array();

$options = array(
    'http' => array(
        'header' => "Content-type: application/x-www-form-urlencoded\r\n" .
                                'Authorization: Basic ' . BASIC_AUTH,
        'method' => 'GET',
        'content' => http_build_query($data)
    )
);

$context = stream_context_create($options);
$result = file_get_contents($domainRequest, false, $context);

$array = json_decode($result, true);

//echo count ($result);
//echo "<br>";
print_r ($array);

如果我只想接收数组的一个条目，我在json_decode ($result); 中没有响应或没有 true，我将收到一个致命错误：无法在 /data/kunden/cylab/ 中使用 stdClass 类型的对象作为数组BH/produktion/web/htdocs_final/brandwatch/brandwatch.php 在第 31 行。

我能做什么？只查看数组的一个条目，我该如何解析它？感谢您的帮助！

【问题讨论】：

你能把brandwatch.php第31行的代码贴出来吗？
请发布echo '<pre>'.print_r($array, true).'</pre>';的输出

【解决方案1】：

如果你真的从请求中得到了那个 json 代码并且你用它来解码它

$array = json_decode($result, true);

您将获得一个与 json 字符串具有相同结构的（关联）数组（没有 true 值，您将获得对象，这就是您遇到致命错误的原因）。在这种情况下，您可以访问其字段，如下所示：

foreach ($array["results"] as $result) {
    echo "id=" . $result["id"] . ", name=" . $result["name"] . "\n";
}

产生输出：

id=1998425622, name=Regionale Mentions_Branche
id=1998422533, name=HTP_Sponsoring
id=1998422529, name=HTP_Brand Mentions
