我想在我的视野中获得一个div的pdf。
我正在做以下事情: 我得到元素,uri编码它的html,然后通过ajax传递给一个方法:
AJAX:
function getPDF(html) {
$.ajax({
type: "POST",
url: "@Url.Action("printPage")",
data: { html: encodeURIComponent(html) }
}).done(function (result) {
window.open("data:application/pdf; " + result);
$("#printArea").html(result);
}).fail(function (data) {
alert("Failed");
});
}
方法:
[HttpPost]
public void printPage(string html)
{
String decoded = System.Uri.UnescapeDataString(html);
var cd = new System.Net.Mime.ContentDisposition
{
FileName = "something.pdf",
Inline = false
};
Response.AppendHeader("Content-Disposition", cd.ToString());
var mem = Bcs.Common.Utilities.HTMLtoPDF.getPDF(decoded);
//var base64EncodedPDF = System.Convert.ToBase64String(pdfByteArray);
Response.BinaryWrite(mem.ToArray());
//return File(mem, System.Net.Mime.MediaTypeNames.Application.Octet);
}
最后我得到一个弹出窗口打开一个pdf,但它不会打开,根据adobe acrobat它已经腐败了。
我尝试将html作为参数发送到方法,但是参数太长了
HTTP Error 404.15 - Not Found The request filtering module is configured to deny a request where the query string is too long.
这样做的好方法。
答案 0 :(得分:0)
public JsonResult printPage(String html)
{
String decoded = System.Uri.UnescapeDataString(html);
var cd = new System.Net.Mime.ContentDisposition
{
FileName = "something.pdf",
Inline = false
};
var mem = Bcs.Common.Utilities.HTMLtoPDF.getPDF(decoded);
mem.Flush();
mem.Position = 0;
String b64Converted = Convert.ToBase64String(mem.ToArray());
return Json(b64Converted, JsonRequestBehavior.AllowGet );
System.Net.Mime.MediaTypeNames.Application.Octet); }
然后在视图中:
$.ajax({
type: "POST",
url: "@Url.Action("printPage")",
data: { html: encodeURIComponent(html) },
}).done(function (result) {
$("#printArea").append('<a href="data:application/pdf;base64,' + result + '">PDF</a>');
}).fail(function (data) {
alert("Failed");
});
显然很容易 只需使用pdf并在json响应中发送它。
