我在使用Aspose.Pdf-Cloud v1.0.9将pdf转换为html时遇到问题。
代码:
public byte[] ConvertPdfToHtml(byte[] doc, string fileName)
{
var pdfApi = new PdfApi(ConfigurationManager.AppSettings["AsposeKey"],
ConfigurationManager.AppSettings["AsposeSID"], ConfigurationManager.AppSettings["AsposeUrl"]);
try
{
var apiResponse = pdfApi.PutConvertDocument("html", null,
Path.GetFileNameWithoutExtension(fileName) + ".html", doc);
if (apiResponse != null && apiResponse.Status.Equals("Ok"))
{
return apiResponse.ResponseStream;
}
throw new Exception("Couldn't convert pdf - " + fileName + " to HTML...");
}
catch (Exception ex)
{
NLogger.LogError("ConvertPdfToHtml - " + ex);
throw;
}
}
似乎无论我上传什么(Adobe,selectPdf),我都会收到400错误请求。有人有幸运气吗?
到目前为止,Aspose.Words对我来说非常适合doc / docx到html。
更新:登录帐户后,看起来在幕后生成错误:
错误:方法或操作未实现。方法:将文档转换为在线指定的格式。参数:format'html',url'',outPath'testadobe.html'
这可能是一个aspose sdk问题,我会尝试联系他们,因为方法暴露在sdk上并完全按照我的需要使用docs,只需要它也可以使用pdf。
更新的代码:
public byte[] ConvertPdfToHtml(byte[] doc, string fileName)
{
var pdfApi = new PdfApi(ConfigurationManager.AppSettings["AsposeKey"],
ConfigurationManager.AppSettings["AsposeSID"], ConfigurationManager.AppSettings["AsposeUrl"]);
var storageApi = new StorageApi(ConfigurationManager.AppSettings["AsposeKey"],
ConfigurationManager.AppSettings["AsposeSID"], ConfigurationManager.AppSettings["AsposeUrl"]);
try
{
storageApi.PutCreate(fileName, "", "", doc);
var apiResponse = pdfApi.GetDocumentWithFormat(fileName, "html", "", "", Path.GetFileNameWithoutExtension(fileName) + ".html");
if (apiResponse != null && apiResponse.Status.Equals("Ok"))
{
var storageRes = storageApi.GetDownload(Path.GetFileNameWithoutExtension(fileName) + ".html", null, "");
var htmlDoc = ZipExtractor.ExtractHtmlFromZip(storageRes.ResponseStream,
Path.GetFileNameWithoutExtension(fileName) + ".html");
return htmlDoc;
}
throw new Exception("Couldn't convert pdf - " + fileName + " to HTML...");
}
catch (Exception ex)
{
NLogger.LogError("ConvertPdfToHtml - " + ex);
throw;
}
}
为后代解压缩功能:
public static byte[] ExtractHtmlFromZip(byte[] zipBytes, string fileName)
{
var zipStream = new MemoryStream(zipBytes);
if(zipStream == null) throw new NullReferenceException("zipStream doesn't contain any bytes...");
var archive = new ZipArchive(zipStream);
foreach (var zipEntry in archive.Entries)
{
if (zipEntry.FullName == fileName)
{
var fileStream = zipEntry.Open();
using (var ms = new MemoryStream())
{
fileStream.CopyTo(ms);
var bytes = ms.ToArray();
return bytes;
}
}
throw new FileNotFoundException("Couldn't find " + fileName + " in zip archive...");
}
throw new Exception("Oops... looks like this should've never been reached in ExtractHtmlFromZip");
}
答案 0 :(得分:1)
我们有两个API可以将PDF文档转换为HTML。
我建议你使用第一个。以下cURL示例将帮助您了解API。
curl -v "http://api.aspose.cloud/v1.1/pdf/Sample.pdf?format=html&appSID=B01A15E5-1B83-4B9A-8EB3-0F2BFA6AC766&signature=hHUw2HKmLY6tQFEevDg52uOLKak" \
-X GET \
-H "Content-Type: application/json" \
-H "Accept: multipart/form-data" \
-o Sample_out.zip
正如您所观察到的,我将输出(-o)文件扩展名设置为.zip而不是.html,原因是转换后的文件包含多个文件(.html,.css,图像文件),所以API压缩输出文件。
此cURL示例使用Sample.pdf作为资源文件。
P.S。我和Aspose一起担任开发人员传道人。
