【问题描述】：
我编写了以下 PHP 函数来尝试生成 PDF：
function createPDF($htmlContent) {
$todayDate = date('Y-m-d--H-i-s');
$this->pdfFilename = $this->upload_dir['basedir'] . '/rns/rns--'. $todayDate . '.pdf';
echo "<br><br>Creating: ". $this->pdfFilename ."<br>";
try {
// create an API client instance
$client = new Pdfcrowd($username, $apikey);
$out_file = fopen($this->pdfFilename, "wb");
echo "<br>HTML:<br><br>" . $htmlContent . "<br><br><br>";
$client->convertHtml($htmlContent, $out_file);
fclose($out_file);
}
catch(PdfcrowdException $why) {
echo "Pdfcrowd Error: " . $why . "<br>";
}
}
在浏览器中运行时，这会正确回显$htmlContent（显示我要转换的HTML，从<html> 到</html> 标签，所以这个变量肯定包含HTML），然后给出以下错误：
Pdfcrowd 错误：[400] 没有要转换的数据。缺少 src 字段。
显然出了点问题，但据我所知，src 字段并没有丢失，因为它在传递给convertHTML() 函数之前的回声非常好。我不确定如何继续，因为 pdfcrowd 似乎没有关于此错误的其他信息或文档。
（Pdfcrowd 文档here）
如果我从 $htmlContent 复制并粘贴 echo'd html 并将其放入 convertHTML() 的第一个参数中，则代码可以工作...那为什么我不能将其作为变量传递呢？不应该一样吗？
有人可以帮忙吗？
注意：我对其他解决方案持开放态度，但我已经尝试过：html2pdf、fpdf、tcpdf、dompdf 和 mpdf。在渲染我需要转换(RNS announcements from London Stock Exchange) 的 html 时，它们都有不同的问题，它可以包含表格和项目符号。见我的other question。我将这些 RNS url 放入 pdfcrowd online converter 得到了很好的结果，所以如果我绕过这个错误，它看起来会起作用......
XML Feed 示例（参见 cmets），这些可以包含多个公告：
<Announcement id_pub="12492736" id_rns="4614Y17" cd_ann_type="POS" cd_ann_med="AFX" id_comp="" id_announcement="12492736" cd_tidm="MKS" id_cont="" cd_ann_corr="" fl_regulatory="Y" fl_copyback="" ts_rel="20150908174008" ts_ann_rec="20150908174008" cd_comp_type="" id_prev_rns="" id_par_rns_num="">

</Announcement>我是这样访问的：
foreach($this->xml->Announcement as $announcement) {
$this->createPDF($announcement->ht_ann);
}
【问题讨论】：
-
你能展示创建
$htmlContent的代码吗？ -
它是直接从一个包含 html 作为字符串
$this->createPDF($announcement->ht_ann);的 xml 提要中提取的，不幸的是，xml 提要被 IP 阻止，只能使用我们的 IP，html 字符串很大，我会尝试包括一个简化的例子 -
如果有帮助，请参阅我为这个问题制作的这个 pdfcrowd 论坛帖子，来自提要的 xml 附在我的第 3 篇帖子中：pdfcrowd.com/forums/read.php?3,2696（也没有人发现这个问题）
