沒用過django。提供一個思路

可以用js獲取。然后傳給python

var refer=document.referrer;
//var sosuo=refer.split(".")[1];
var sosuo = domainURI(refer);
var grep=null;
var str=null;
var keyword=null;
var wd = '';
switch(sosuo){
    case "www.baidu.com":
        grep = /wd\=.*\&/i;
        str=refer.match(grep);
        keyword=str.toString().split("=")[1].split("&")[0];
        wd =decodeURIComponent(keyword);
      break;
    case "m.baidu.com":
        grep = /word\=.*\&/i;
        str=refer.match(grep);
        keyword=str.toString().split("=")[1].split("&")[0];
        wd =decodeURIComponent(keyword);
      break;
    case "image.baidu.com":
        grep = /word\=.*\&/i;
        str=refer.match(grep);
        keyword=str.toString().split("=")[1].split("&")[0];
        wd =decodeURIComponent(keyword);
      break;

        grep = /&query\=.*/i;
        str=refer.match(grep);
        keyword=str.toString().split("&")[1].split("=")[1];
