我需要在我的 PHP 代码中集成 HelloSign API。我按照这种方式进行操作，但 iframe 不会出现。
<script type="text/javascript" src="https://s3.amazonaws.com/cdn.hellosign.com/public/js/hellosign-embedded.LATEST.min.js"></script>
<!-- Script code -->
<script type="text/javascript">
HelloSign.init("0005fc6cf93ce7ce6116778265107d5a");
HelloSign.open({
url: "https://app.hellosign.com/editor/embeddedSign?signature_id=78caf2a1d01cd39cea2bc1cbb340dac3&token=b6b8e7deaf8f0b95c029dca049356d4a2cf9710a",
uxVersion: 2,
allowCancel: true,
debug: true,
skipDomainVerification: true,
height: 640
});
</script>
控制台错误：
{url: "https://app.hellosign.com/editor/embeddedSign?sign…c3&token=b6b8e7deaf8f0b95c029dca049356d4a2cf9710a", uxVersion: 2, allowCancel: true, debug: true, skipDomainVerification: true, …}
