外贸开发，用java调用速卖通api第一步，token的获取。

浏览数：17 / 时间：2015年06月08日

第一步定义速卖通api的常量

public String client_id;
public String client_key;
public String site;

第二步获取登陆的uRL

    /**
     * getloginurl
     * @param redirect_uri
     * @return
     */
    public String GetLoginUrl(String redirect_uri)
    {
        String param = (new StringBuilder("client_id=")).append(client_id).append("&site=aliexpress&redirect_uri=").append(redirect_uri).toString();
        String param1 = (new StringBuilder("client_id")).append(client_id).append("redirect_uri").append(redirect_uri).append("site").append(site).toString();
        String sign = hmac_sha1(param1, client_key).toUpperCase();
        return (new StringBuilder("http://gw.api.alibaba.com/auth/authorize.htm?")).append(param).append("&_aop_signature=").append(sign).toString();
    }

第三步获取速卖通 toaken

/**
    * 根据店铺名获取token
    * @param shopname
    * @return
    */
    public String gettokenbyshopname(String shopname)
    {
    String sql= "select FShop_tokenyear,FShop_SysUser from t_smt_shop where fshop_name=‘" + shopname +"‘“

     Map mapmain=(Map) Base1.getMapbySQL(sql);
        String token  = "";

       String tokenyear  =(String)mapmain.get("FShop_tokenyear");
  String ShopName   =(String)mapmain.get("FShop_Name");
String FShop_SysUser =(String)mapmain.get("FShop_SysUser");
String rt    = GetTokenByTokenYear(tokenyear);
  try
   {
   JSONObject jsonObject = JSONObject.fromObject( rt );
   token=jsonObject.get("access_token").toString();
   }
   catch(Exception ex)
   {
    String subject= FShop_SysUser+"的速卖通店铺"+ ShopName+"登陆失效请重新登陆";
    Base1.sendmail(subject,"","mail"); //todo 修改为32
    return "broke";
   }
   return token;
    }
