从其js里面找到关键代码：
toPmDetai: function(t) {
var e = t.user_key + "?doctor_user_id=" + t.doctor.user_id,
i = "/pm/" + e + "&t=" + this.$md5(t.user_key + "aYMX5Wk7Cu");
this.$router.push(i)
}
user_key在json里面：
{
"user_id": "31333718",
"name": "\u66f4\u7f8e\u7528\u6237mdahaNMQXq",
"can_conversation": true,
"user_key": "21321929_31333718",
"interest": "",
"city_name": "\u5170\u5dde",
"id": 13946279
}
21321929_29940136aYMX5Wk7Cu
根据这句话获得t。
