我有以下ajax调用:
$.ajax({
url: 'WebService.asmx/ConvertPDF',
data: "{'section':'<html><head></head><body>Ajax html</body></html>'}",
type: 'POST',
contentType: 'application/json; charset=utf-8',
dataType: 'JSON',
async: false,
success: function (response) {
// proceed
},
error: function () {
// fail code
}
});
和网络服务
[WebMethod(EnableSession = true)]
public void ConvertPDF(string section) {
HtmlToPdf convertor = new HtmlToPdf();
string _html = "<html><head></head><body><p>this is a test</p></body></html";
string size = "A4", orientation = "Portrait";
PdfPageSize pdfSize = (PdfPageSize)Enum.Parse(typeof(PdfPageSize), size, true);
PdfPageOrientation pdfOrientation = (PdfPageOrientation)Enum.Parse(typeof(PdfPageOrientation), orientation, true);
convertor.Options.PdfPageSize = pdfSize;
convertor.Options.PdfPageOrientation = pdfOrientation;
convertor.Options.WebPageWidth = 1024;
convertor.Options.MinPageLoadTime = 2;
convertor.Options.WebPageHeight = 0;
PdfDocument doc = convertor.ConvertHtmlString(_html, "");
doc.Save(HttpContext.Current.Response, false, "Sample.pdf");
doc.Close();
}
在本地运行服务方法,它工作正常,但是当我通过JS按钮调用ajax时,我得到"线程正在中止"。
关于如何绕过它的任何想法?基本上,按钮从页面上的部分中抓取html,并(最终(将其传递给方法以输出为PDF,实质上是将_html变量替换为section参数中的内容。
谢谢
//使用 selectpdf 将 Html 转换为 pdf 的 Post 方法
[HttpPost]
public ActionResult ConvertDocument(MyDocumentDTO model)
{
HtmlToPdf converter = new HtmlToPdf();
PdfDocument doc = converter.ConvertHtmlString(model.Context);
// save pdf document
byte[] pdf = doc.Save();
string handle= Guid.NewGuid().ToString();
TempData[handle] = pdf;
return Json(handle, JsonRequestBehavior.AllowGet);
}
阿贾克斯调用
$.ajax({
url: '/document/ConvertDocument',
type: 'POST',
contentType: 'application/json; charset=utf-8',
data: ko.toJSON(document),
success: function (data) {
window.location = 'download?fileGuid=' + data;
},
获取下载文件的请求
[HttpGet]
public ActionResult Download(string fileGuid)
{
byte[] pdf = TempData[fileGuid] as byte[];
FileResult fileResult = new FileContentResult(pdf, "application/pdf");
fileResult.FileDownloadName = "Document.pdf";
return fileResult;
}
