里面有一个signToken,我们该如何获取signToken的值呢？

用chrome访问http://e.waimai.meituan.com/v2/order/history 这个页面后，发现有一个

http://e.waimai.meituan.com/static/59229326/js/page/order/history.js 比较可疑，

于是拿出来分析，通过查询发现里面有signToken

经过分析，得到大概是下面这段js代码

define(‘module/ajax_util‘,["module/interface"],function(e){var r=jQuery.ajax,t=$(".J-csrf-token"),n=$(".J-sign-token"),a=t.val(),o=n.val(),d=[e.order.getNewOrderFromInterval,e.order.queryProcessedOrderList,e.order.queryHisOrderList];t.remove(),n.remove();var i=function(r){return r&&r.indexOf(e.order.queryHisOrderList)>-1?100007:r&&r.indexOf(e.order.recipientPhone)>-1?100008:r&&r.indexOf(e.order.getPrintOrderInfo)>-1?100009:null},u=location.origin,s=function(e){var r=[];for(var t in e)r.push(t+"="+e[t]);return r.join("&")},f=function(e,r){for(var t=0,n=e.length;n>t;t++)if(r&&-1!==r.indexOf(e[t]))return!0},c=function(e){
    if(e){
        for(var r="",t=0,n=e.length;n>t;t++)
            r+=String.fromCharCode(2^e.charCodeAt(t));
        return r
    }return""
},l=c(o);

$.ajax=function(e){e.type&&"post"===e.type.toLowerCase()&&(e.data&&"function"==typeof e.data.append?e.data.append("csrfToken",a):e.data=$.extend(e.data||{},{csrfToken:a}))
,f(d,e.url)&&(e.data&&"function"==typeof e.data.append?e.data.append("signToken",l):e.data=$.extend(e.data||{},{signToken:l}));
var t=function(e,r,t){};e.success&&jQuery.isFunction(e.success)&&(t=e.success),e.success=function(e,r,n){4001===e.code?alert(e.msg):4002===e.code?top.location.reload():1017===e.code?alert(e.msg):t(e,r,n)};var n=function(e,r,t){};"function"==typeof e.error&&(n=e.error),e.error=function(r,t,a){n(r,t,a);({eventTime:Math.floor((new Date).getTime()/1e3),responseCode:r.status,url:e.url,param:e.data,msg:t})};
var o=i(e.url);if(o){Rohr_Opt.Flag=o;var c=s(e.data?e.data:{});Rohr_Opt.reload(u+e.url+(c?(e.url.indexOf("?")>-1?"&":"?")+c:"")),e.data?e.data._token=rohrdata:e.data={_token:rohrdata}
}return r(e)
}
});

signToken的取值：

1.获取http://e.waimai.meituan.com/v2/order/history 页面隐藏表单域J-sign-token的值

<input type="hidden" class="J-sign-token" value="27QvFyIlNgjmVrfv9hfqcHKe1vOzRCJYBOlBnwww6joDSgFbJw5Kg9lfyDUpbrLWF0IlusK5aWMEXnO9QGwtCbDoLNvwhrfxbCZ/c96m/wi+OIn1y7fZhWGLpxL6pd3ZFwoGEObTxuq2+aC281PTJg=="/>

2.通过以下算法得到r的值，即为signToken

for(var r="",t=0,n=e.length;n>t;t++)
     r+=String.fromCharCode(2^e.charCodeAt(t));
