我需要获取带有已执行 js 的 html，为此我安装了 phantomjs，但在获取内容时，我仍然有旧的 html，带有旧数据，数据应该由 js 脚本处理，并且应该更改为带有某个类的 span 标签，该脚本应该执行。我正确理解，当我打开获取内容时，我应该获取带有处理数据的 DOM，这意味着标签跨度而不是 json 元素？我mssed什么？
public function getContentByPhantomjs($url)
{
$client = Client::getInstance();
$client->getEngine()->addOption('--ssl-protocol=any');
$client->getEngine()->addOption('--ignore-ssl-errors=true');
$client->getEngine()->addOption('--web-security=false');
$client->getEngine()->setPath(MY_PATH . 'bin/phantomjs');
$request = $client->getMessageFactory()->createRequest($url, 'GET');
$response = $client->getMessageFactory()->createResponse();
// Send the request
$client->send($request, $response);
return $response->getStatus() === 200 ? $response->getContent() : false;
}
但是js没有执行，我没有处理#pretty_json_id中的数据
<div class="headline">
<div id="pretty_json_id">
<pre>
{"Company":"test"}
</pre>
</div>
<script>
function ready() {
element = document.getElementById('pretty_json_id').getElementsByTagName('pre');
if (element.length > 0) {
let parseJson = JSON.parse(element[0].innerHTML);
let stringifyJson = JSON.stringify(parseJson, undefined, 4);
element[0].innerHTML = syntaxHighlight(stringifyJson);
}
}
function syntaxHighlight(json) {
json = json.replace(/&/g, '&').replace(/</g, '<').replace(/>/g, '>');
return json.replace(/("(\\u[a-zA-Z0-9]{4}|\\[^u]|[^\\"])*"(\s*:)?|\b(true|false|null)\b|-?\d+(?:\.\d*)?(?:[eE][+\-]?\d+)?)/g, function (match) {
var cls = 'number';
if (/^"/.test(match)) {
if (/:$/.test(match)) {
cls = 'key';
} else {
cls = 'string';
}
} else if (/true|false/.test(match)) {
cls = 'boolean';
} else if (/null/.test(match)) {
cls = 'null';
}
return '<span class="' + cls + '">' + match + '</span>';
});
}
document.addEventListener("DOMContentLoaded", ready);
</script>
在浏览器中，everythink 工作。但我需要存在执行 js 的 html
