.net6+aspose.words导出word并转pdf

本文使用net6框架，aspose.word破解激活并兼容net6，导出word模板并兼容识别html并给其设置字体，前端直接浏览器下载，后端保存文件并返回文件流，还有批量导出并压缩zip功能

1、安装Aspose.Words的nuget包选择21.8.0 版本(此版本可用于net6)。本文破解这个版本免费无水印，可适用21.8.0以下至18.x以上。

2、代码：

using Aspose.Words;

using Aspose.Words.Saving;

/// <summary>
/// 导出word
/// </summary>
/// <returns></returns>
[HttpPost("export")]
public IActionResult ExportWrod(string userid)

{

//载入模板
Document doc = new Document();
// 创建DocumentBuilder对象，用于在文档中添加内容
DocumentBuilder builder = new DocumentBuilder(doc);

// 创建一个新的段落
Paragraph para = builder.InsertParagraph();

para.ParagraphFormat.Alignment = ParagraphAlignment.Center; //段落居中
para.ParagraphFormat.LineSpacingRule = LineSpacingRule.Exactly; //行距固定值
para.ParagraphFormat.LineSpacing = 22; //行距-固定值
para.ParagraphFormat.SpaceBefore = 12; //段前
para.ParagraphFormat.SpaceAfter = 12; //段后
// 在段落中添加文本
Run header = new Run(doc, "文本");
header.Font.Size = 22;
header.Font.Bold = true; //加粗
header.Font.Name = "创艺简标宋"; //字体
para.AppendChild(header);

//处理含html文本的数据到word中

builder.Font.Size = 12;
builder.Font.Name = "创艺简楷体";
builder.InsertHtml("<p>含html的文本</p>", true); //(true可设置builder的格式)

//目前激活码只找到Aspose.Word 21.8版本，找不到更高的版本了。
//激活之后可去除水印等等，添加下面代码即可
//原文https://www.cnblogs.com/cqpanda/p/16475319.html

new Aspose.Words.License().SetLicense(new MemoryStream(Convert.FromBase64String(asposeKey)));

const string saveFold = "../word/";
string outputPath = saveFold;
if (!Directory.Exists(outputPath))
{
Directory.CreateDirectory(outputPath);
}

doc.Save(outputPath);

//如有需求转pdf则添加以下代码

String genWrod= "/自己的目录/刚才生成的word.docx";

Document doc1 = new Document(genWrod);
// 设置 PDF 转换选项
PdfSaveOptions pdfSaveOptions = new PdfSaveOptions
{
SaveFormat = SaveFormat.Pdf,
EmbedFullFonts = true,
};
//保存为 PDF 文件
doc1.Save(saveFold + "/pdfs.pdf", pdfSaveOptions);

#region 文件下载
//修改utf8编码，不然可能汉字会乱码
string encodedFileName = System.Web.HttpUtility.UrlEncode(fileName.Replace("/", ""), System.Text.Encoding.UTF8);
byte[] fileBytes = memoryStream.ToArray();
// 设置响应头，指定文件类型和文件名
var contentDisposition = new ContentDispositionHeaderValue("attachment")
{
FileName = encodedFileName
};
Response.Headers.Add("Content-Disposition", contentDisposition.ToString());
// 设置Content-Type，这里是根据文件类型设置
var contentType = "application/octet-stream";
Response.Headers.Add("Content-Type", contentType);
#endregion

return File(fileBytes, contentType); //返回文件流，可以直接在浏览器直接下载

}

前端代码：

//下载报告,直接在浏览器下载

function downloadMyReport() {

var cellData = {

"userid": userId

};

$.ajax({

url: prefix + "new/api/Export/export?userid=" + userId, // 替换为你的API地址

type: 'POST',

data: {

userid: userId // 用户ID

},

xhrFields: {

responseType: 'blob' //设置二进制

},

success: function (data, status, xhr) {

//获取header中的内容

var contentDispositionHeader = xhr.getResponseHeader('Content-Disposition');

var fileName = contentDispositionHeader ? contentDispositionHeader.split('filename=')[1] : 'default_filename.docx';

//需要对汉字编码否则会可能会路阿妈

var decodedFileName = decodeURIComponent(fileName);

// 创建Blob对象

var blob = new Blob([data], { type: 'application/octet-stream' });

// 创建临时URL并分配给一个链接

var url = window.URL.createObjectURL(blob);

var a = document.createElement('a');

a.href = url;

a.download = decodedFileName;

document.body.appendChild(a);

a.click();

}

});

}

3、如需要批量导出并压缩zip看下面代码思路

List<BatchExportWord> batchExportWordList = new List<BatchExportWord>();
//此处循环上第2步骤的思路即可

foreach (var process in processList)

{

#region此处写第2部分绘画word的代码即可

Document doc = new Document();

// 创建DocumentBuilder对象，用于在文档中添加内容
DocumentBuilder builder = new DocumentBuilder(doc);

......................

#endregion

//下面填充batchExportWordList集合存放批量word字节集合

using (MemoryStream stream = new MemoryStream())
{
doc.Save(stream, SaveFormat.Docx);
batchExportWordList.Add(new BatchExportWord()
{
Byte = stream.ToArray(),
Name = wordname
}); ;
}

} //foreach结尾

#region 批量压缩word到zip中
// 使用GZipStream进行压缩并写入文件
Guid guid = Guid.NewGuid();
string file_name = DateTime.Now.ToString("yyyyMMddhhmmss") + guid + ".zip";
using (FileStream zipStream = new FileStream(outputPath + "/" + file_name, FileMode.Create))
using (ZipArchive zipArchive = new ZipArchive(zipStream, ZipArchiveMode.Create))
{
// 遍历字word节流集合并将每个字节流写入 ZIP 文件的一个条目
foreach (var item in batchExportWordList)
{
var entry = zipArchive.CreateEntry(item.Name.Replace("/", "") + ".docx"); // 注意此处名字里如果有"/"的话会自动根据杠压缩多层层文件夹
using (var entryStream = entry.Open())
{
entryStream.Write(item.Byte, 0, item.Byte.Length); //把字节写入生成
}
}
}
#endregion
