实战：
1.引入js

2.html

3.js

var string = window.location.search; //获取url过来的参数
    // console.log(string)
    var str = string.split('=')[1];
    // console.log(str)
    var s = str.split("+")
    // console.log(s)
    if (typeof(s[2]) == 'undefined' || s[2] =='') {
        s[2] = false;
    }
    // var url = s[0] +"filepreview/loadFileByPdfObject?fileId=" + s[1];
    var url = s[0] +"filepreview/loadFile?isNeedWaterMark="+ s[2]+"&fileId=" + s[1];
    var op = {
        withd:"920px",
        height:"460px"
    }
    console.log(url);
    // 我的pdf文件放在项目的pdf文件夹下，名字叫做Java.pdf
    PDFObject.embed("Java.pdf", "#my-container", options);
//url为远程连接，也就是后端输出pdf流的地方    
PDFObject.embed(url,'#pdfs',op);
    
   

注意 后端输出需要设置为

response.setContentType("application/pdf;charset=UTF-8");
application：某二进制的一个附件
octet-stream：子类型，不确定下载文件的通用指定
pdf：指定为PDF
