Question

问题是CSS没有应用，图像没有在PDF中呈现。这仅发生在暂存和生产环境中。无法在我的开发环境中重新创建问题。

两者都在https下，图像和CSS文件的链接是http。所以，我改变了我的开发环境以使用https来查看这是否是问题。它没有任何区别。

这是我用于从HTML呈现PDF的代码（我没有写它，它的代码很旧）：

Doc theDoc = new Doc();
theDoc.HtmlOptions.Engine = EngineType.Gecko;
theDoc.HtmlOptions.UseScript = true;
theDoc.HtmlOptions.Media = MediaType.Screen;
theDoc.HtmlOptions.AutoTruncate = true;

XHtmlOptions.GeckoSubsetType options = theDoc.HtmlOptions.GeckoSubset;
options.AddLinks = true;

//Write the CSS to PDF
StringBuilder coreCssBuilder = new StringBuilder();
StringWriter coreCssWriter = new StringWriter(coreCssBuilder);
HtmlTextWriter coreCssHtmlWriter = new HtmlTextWriter(coreCssWriter);
lnkCoreCss.RenderControl(coreCssHtmlWriter);

String coreCssHtml = coreCssBuilder.ToString().Replace("href=\"..", "href=\"http://example.com");

StringBuilder testTranscriptCssBuilder = new StringBuilder();
StringWriter testTranscriptCssWriter = new StringWriter(testTranscriptCssBuilder);
HtmlTextWriter testTranscriptCssHtmlWriter = new HtmlTextWriter(testTranscriptCssWriter);
lnkTestTranscriptCss.RenderControl(testTranscriptCssHtmlWriter);

String testTranscriptCssHtml = testTranscriptCssBuilder.ToString().Replace("href=\"..", "href=\"http://example.com");

StringBuilder templateTableCssBuilder = new StringBuilder();
StringWriter templateTableCssWriter = new StringWriter(templateTableCssBuilder);
HtmlTextWriter templateTableCssHtmlWriter = new HtmlTextWriter(templateTableCssWriter);
lnkTemplateTableCss.RenderControl(templateTableCssHtmlWriter);

String templateTableCssHtml = templateTableCssBuilder.ToString().Replace("href=\"..", "href=\"http://example.com");

StringBuilder extraCssBuilder = new StringBuilder();
StringWriter extraCssWriter = new StringWriter(extraCssBuilder);
HtmlTextWriter extraCssHtmlWriter = new HtmlTextWriter(extraCssWriter);
styleExtraCss.RenderControl(extraCssHtmlWriter);

String extraCssHtml = extraCssBuilder.ToString().Replace("</style>", ".BorderCell {border: none;}</style>");

StringBuilder transcriptBuilder = new StringBuilder();
StringWriter transcriptWriter = new StringWriter(transcriptBuilder);
HtmlTextWriter transcriptHtmlWriter = new HtmlTextWriter(transcriptWriter);

pnlTranscript.RenderControl(transcriptHtmlWriter);

//Add the transcript html to the PDF
String transcriptHtml = transcriptBuilder.ToString()
    .Replace("src=\"/", "src=\"http://example.com/")
    .Replace("src=\"../", "src=\"http://example.com/");

//Add the page CSS to the PDF
transcriptHtml = coreCssHtml + testTranscriptCssHtml + templateTableCssHtml + extraCssHtml + transcriptHtml;

int pageId = theDoc.AddImageHtml(transcriptHtml);

while (true)
{
    if (!theDoc.Chainable(pageId))
        break;
    theDoc.Page = theDoc.AddPage();
    pageId = theDoc.AddImageToChain(pageId);
}

//Flatten pages
for (int i = 1; i <= theDoc.PageCount; i++)
{
    theDoc.PageNumber = i;
    theDoc.Flatten();
}

return theDoc;

任何人都可以帮忙吗？

事实证明，存储CSS和图像的网站没有正确的DNS设置，以便我的登台和制作环境可以访问它。

调整了DNS设置，现在可以使用了。
