1、最开始用的spire.doc,但是spire.doc只能在windows上使用,部署到docker上无法使用,原因是spire.doc使用了库 system.drawing.common
2、 之后使用aspose.words,示例代码如下:
public static void run() { document doc = new document(@"d:\testhtml.html"); doc.save(@"d:\aspose_word.docx"); }
可以在windows使用,也可以在linux上使用。不过免费版有水印
3、最后找到了一个库叫sautinsoft.document。可以实现功能,可以linux上使用,并且没有水印。示例代码如下
public static void convertfromstream() { // we need files only for demonstration purposes. // the conversion process will be done completely in memory. string inpfile = @"d:\testhtml2.html"; string outfile = @"d:\sautinsoft_word2.docx"; byte[] inpdata = file.readallbytes(inpfile); byte[] outdata = null; using (memorystream msinp = new memorystream(inpdata)) { // load a document. documentcore dc = documentcore.load(msinp, new sautinsoft.document.htmlloadoptions()); // save the document to docx format. using (memorystream outms = new memorystream()) { dc.save(outms, new docxsaveoptions()); outdata = outms.toarray(); } // show the result for demonstration purposes. if (outdata != null) { file.writeallbytes(outfile, outdata); system.diagnostics.process.start(new system.diagnostics.processstartinfo(outfile) { useshellexecute = true }); } }
html转doc给前端返回文件的base64示例代码如下:
byte[] inpdata = file.readallbytes(htmlpath); using var msinp = new memorystream(inpdata); documentcore dc = documentcore.load(msinp, new sautinsoft.document.htmlloadoptions()); using memorystream outms = new memorystream(); dc.save(outms, new docxsaveoptions()); var outdata = outms.toarray(); var fileresult = new downfileresult { filename = $"word_name.doc", base64str = convert.tobase64string(outdata) };
