遍历接口参数，自动计算url并进行签名

我们先选个接口，如路径规划接口，会出现Fromx ，y；Tox，y。两种参数，分别要所有城市进行便利（所有城市坐标经纬度，可以通过爬虫从高德地图上爬下来），具体方法请搜博客园

代码如下：

#encoding:utf-8
#遍历所有城市路径规划的测试脚本

    ret = []
    u = urlparse.urlparse(url)
    qs = u.query
    pure_url = url.replace('?'+qs, '')
    #print pure_url
    qs_dict = dict(urlparse.parse_qsl(qs))
    tmp_dict = copy.deepcopy(qs_dict)
    tmp_dict['fromX'] = fromX
    tmp_dict['fromY'] = fromY
    tmp_dict['toX'] = toX
    tmp_dict['toY'] = toY
    tmp_dict['sign'] = sign

    ret.append(pure_url + "?" + tmp_qs)
    return ret

 代码不知道大家能否看懂，如有不懂请留言

便利需要用到的 fromX，Y，toX，Y。产生新的url
