对于get请求

url = "http://api.map.baidu.com/geocoder/v2/?address=百度大厦&output=json&ak=yourak"

sk = "yoursk"

按照官网python写法改下就好，urllib.quote  urllib.quote_plus分别表示部分字符不编码的urlencode和全部编码的urlencode

post请求

按照post参数首字母从小到大排列组成url，其他与get相同，如:

创建表:http://api.map.baidu.com/geodata/v3/geotable/create

geotype = 1

is_published = 1

name = table333

ak = yourak

则基础url为:/geodata/v3/geotable/create?ak=yourak&geotype=1&is_published=1&name=table3

rawStr = baseurl

string encode_url = CHttpclient::UrlEncode_safe(rawStr);    //一些字符不变的urlencode

encode_url += "yoursk";

string second_encode = CHttpclient::UrlEncode(encode_url);  //全部字符urlencode

md5(second_encode)
