Question

我在服务器端创建PDF文件，并在servlet请求时返回此文件。我正在使用jquery ajax调用检索这个，但是是在给我解析错误，可能是什么原因？

服务器端代码

response.setHeader("Pragma", "no-cache");
response.setDateHeader("Expires", 0);
response.setContentType("application/pdf");
String fileName = "Vendormaster.pdf";
response.setHeader("Content-Disposition","attachment; filename=\"" + fileName  + "\"");
RandomAccessFile f = new RandomAccessFile("D:/PDF_1.pdf", "r");
byte[] pdfBytes= new byte[(int)f.length()];
f.read(pdfBytes);
ServletOutputStream out = response.getOutputStream();
response.setContentLength(pdfBytes.length);
out.write(pdfBytes);
out.flush();

调用Ajax

function GetData(url){  var dataObject=[];  $.ajax({

        url : url,
        type : "GET",
        async : false,
        dataType : 'json',
        contentType : "application/json",
        beforeSend:function(){ //           $("#ajaxloader").fadeIn();      },
        success : function(data, textStatus, jqXHR) {        dataObject= data; //        $("#ajaxloader").fadeOut(0);

        },
        error : function(data,b,c) {
            var error; //           $("#ajaxloader").fadeOut(0);
                return null;
        }

来自Live Http标题的标题
