继续前面一篇随笔《淘宝API开发系列---淘宝API的测试及使用》，来继续介绍淘宝API的具体代码开发部分，上篇主要是介绍淘宝SDK开发的一些流程及必备的信息，以及掌握如何学会利用API文档、淘宝API测试工具来获取我们所需的数据，其中我一般倾向于获取Json数据，然后进行分析，其中Json数据可以通过JsonView工具（http://jsonviewer.codeplex.com/）进行格式化显示，方便我们了解和区分各个属性的信息。另外淘宝的SDK里面，封装了很多对象，我们通过数据就可以获取到相关的信息了，不过注意的就是，我们每个接口调用，都要传入Fields的属性，如果我们没有指定相应的属性字段，那么接口返回的数据，就没有这项的，淘宝SDK的对象属性就会为空。
通过以上的工具，我们就能可视化属性的信息了，对接口数据的理解就更加清晰，首先我们来看看我测试例子的运行效果如下所示。
其中上面例子的代码如下所示。
private void TestUserGet()
{
//单独用户的信息
Console.WriteLine("单独用户的信息");
UserGetRequest req = new UserGetRequest(); //实例化具体API对应的Request类
req.Fields = "user_id,nick,created,buyer_credit,type,sex";
req.Nick = "wuhuacong";
UserGetResponse rsp = myclient.Execute(req);//执行API请求并将该类转换为response对象
Console.WriteLine(rsp.Body);
if (rsp.User != null)
{
//Console.WriteLine(rsp.User.Nick);
//Console.WriteLine(ObjectToString(rsp.User));
List<User> list = new List<User>();
list.Add(rsp.User);
this.winGridView1.DisplayColumns = req.Fields.Replace("_", "");//对应字段的属性没有“_”字符的
this.winGridView1.DataSource = list;
}
}
private void TestItemGet()
{
//单独商品的信息
Console.WriteLine("单独商品的信息");
ItemGetRequest req = new ItemGetRequest();
req.Fields = "num_iid,title,nick,pic_path,cid,price,type,location.city,delist_time,post_fee";
req.NumIid = 3838293428L;
ItemGetResponse itemRsp = myclient.Execute(req);
if (itemRsp != null && itemRsp.Item != null)
{
//Console.WriteLine(itemRsp.Item.Nick);
//Console.WriteLine(ObjectToString(itemRsp.Item));
List<Item> list = new List<Item>();
list.Add(itemRsp.Item);
this.winGridView1.DisplayColumns = req.Fields.Replace("_", "");//对应字段的属性没有“_”字符的
this.winGridView1.DataSource = list;
}
}
private void TestItemSearch()
{
//查询商品信息（不含类别）
Console.WriteLine("查询商品信息（不含类别）");
ItemsGetRequest req = new ItemsGetRequest();
req.Fields = "num_iid,title,nick,pic_url,cid,price,type,delist_time,post_fee,score,volume";//,location.city,location.state";
req.Q = "笔记本";
//itemReq.Cid = "14";
req.OrderBy = "volume:desc";
req.PageNo = 1;
req.PageSize = 40;
//显示列表信息
ItemsGetResponse itemRsp = myclient.Execute(req);
if (itemRsp != null)
{
//Console.WriteLine(itemRsp.TotalResults);
//foreach (Item item in itemRsp.Items)
//{
// Console.WriteLine(ObjectToString(item));
//}
this.winGridView1.DisplayColumns = req.Fields.Replace("_", "");//对应字段的属性没有“_”字符的
this.winGridView1.DataSource = itemRsp.Items;
}
{
//单独用户的信息
Console.WriteLine("单独用户的信息");
UserGetRequest req = new UserGetRequest(); //实例化具体API对应的Request类
req.Fields = "user_id,nick,created,buyer_credit,type,sex";
req.Nick = "wuhuacong";
UserGetResponse rsp = myclient.Execute(req);//执行API请求并将该类转换为response对象
Console.WriteLine(rsp.Body);
if (rsp.User != null)
{
//Console.WriteLine(rsp.User.Nick);
//Console.WriteLine(ObjectToString(rsp.User));
List<User> list = new List<User>();
list.Add(rsp.User);
this.winGridView1.DisplayColumns = req.Fields.Replace("_", "");//对应字段的属性没有“_”字符的
this.winGridView1.DataSource = list;
}
}
private void TestItemGet()
{
//单独商品的信息
Console.WriteLine("单独商品的信息");
ItemGetRequest req = new ItemGetRequest();
req.Fields = "num_iid,title,nick,pic_path,cid,price,type,location.city,delist_time,post_fee";
req.NumIid = 3838293428L;
ItemGetResponse itemRsp = myclient.Execute(req);
if (itemRsp != null && itemRsp.Item != null)
{
//Console.WriteLine(itemRsp.Item.Nick);
//Console.WriteLine(ObjectToString(itemRsp.Item));
List<Item> list = new List<Item>();
list.Add(itemRsp.Item);
this.winGridView1.DisplayColumns = req.Fields.Replace("_", "");//对应字段的属性没有“_”字符的
this.winGridView1.DataSource = list;
}
}
private void TestItemSearch()
{
//查询商品信息（不含类别）
Console.WriteLine("查询商品信息（不含类别）");
ItemsGetRequest req = new ItemsGetRequest();
req.Fields = "num_iid,title,nick,pic_url,cid,price,type,delist_time,post_fee,score,volume";//,location.city,location.state";
req.Q = "笔记本";
//itemReq.Cid = "14";
req.OrderBy = "volume:desc";
req.PageNo = 1;
req.PageSize = 40;
//显示列表信息
ItemsGetResponse itemRsp = myclient.Execute(req);
if (itemRsp != null)
{
//Console.WriteLine(itemRsp.TotalResults);
//foreach (Item item in itemRsp.Items)
//{
// Console.WriteLine(ObjectToString(item));
//}
this.winGridView1.DisplayColumns = req.Fields.Replace("_", "");//对应字段的属性没有“_”字符的
this.winGridView1.DataSource = itemRsp.Items;
}
}
对于需要获取用户私密信息，如买入卖出等重要信息，还需要获取用户的SessionKey的，我们可以通过下面接口函数，弹出登录窗口，然后登录后，定位到对应的App应用页面，然后页面加载的时候，获取到对应的SessionKey、
/// <summary>
/// 判断是否顺利获取SessionKey
/// </summary>
/// <returns></returns>
private string GetAuthorizeCode(string appKey)
{
string authorizeCode = "";
FrmAuthorized dlg = new FrmAuthorized();
dlg.AppKey = appkey;
if (dlg.ShowDialog() == DialogResult.OK)
{
authorizeCode = dlg.AuthrizeCode;
}
if (string.IsNullOrEmpty(authorizeCode)) return null;
string sessionKeyUrl = string.Format(TOP_AUTH_URL, authorizeCode);
HttpHelper helper = new HttpHelper();
string html = helper.GetHtml(sessionKeyUrl);
//格式
//top_appkey=1142&top_parameters=xxx&top_session=xxx&top_sign=xxx&encode=utf-8
string reg = ".*?&top_session=(?<session>.*?)&top_sign";
string sessionKey = CRegex.GetText(html, reg, 1);
return sessionKey;
/// 判断是否顺利获取SessionKey
/// </summary>
/// <returns></returns>
private string GetAuthorizeCode(string appKey)
{
string authorizeCode = "";
FrmAuthorized dlg = new FrmAuthorized();
dlg.AppKey = appkey;
if (dlg.ShowDialog() == DialogResult.OK)
{
authorizeCode = dlg.AuthrizeCode;
}
if (string.IsNullOrEmpty(authorizeCode)) return null;
string sessionKeyUrl = string.Format(TOP_AUTH_URL, authorizeCode);
HttpHelper helper = new HttpHelper();
string html = helper.GetHtml(sessionKeyUrl);
//格式
//top_appkey=1142&top_parameters=xxx&top_session=xxx&top_sign=xxx&encode=utf-8
string reg = ".*?&top_session=(?<session>.*?)&top_sign";
string sessionKey = CRegex.GetText(html, reg, 1);
return sessionKey;
最后我们看看其中获取已买记录的接口实现如下所示。
private void TestBuyInfo()
{
if (string.IsNullOrEmpty(sessionKey))
{
sessionKey = GetAuthorizeCode(this.appkey);
}
//买入交易
Console.WriteLine("买入交易");
TradesBoughtGetRequest req = new TradesBoughtGetRequest();
//req.Fields = "tid,title,price,type,num_iid,seller_nick,buyer_nick,status";
req.Fields = "tid,title,price,type,num_iid,seller_nick,buyer_nick,status,receiver_state,receiver_city,receiver_district,receiver_address";
req.PageNo = 1L;
req.PageSize = 40L;
TradesBoughtGetResponse rsp = myclient.Execute(req, sessionKey);
if (rsp != null)
{
//Console.WriteLine(rsp.Trades.Count);
//if (rsp.Trades.Count > 0)
//{
// foreach (Trade item in rsp.Trades)
// {
// Console.WriteLine(ObjectToString(item));
// }
//}
this.winGridView1.DisplayColumns = req.Fields.Replace("_", "");//对应字段的属性没有“_”字符的
this.winGridView1.DataSource = rsp.Trades;
}
{
if (string.IsNullOrEmpty(sessionKey))
{
sessionKey = GetAuthorizeCode(this.appkey);
}
//买入交易
Console.WriteLine("买入交易");
TradesBoughtGetRequest req = new TradesBoughtGetRequest();
//req.Fields = "tid,title,price,type,num_iid,seller_nick,buyer_nick,status";
req.Fields = "tid,title,price,type,num_iid,seller_nick,buyer_nick,status,receiver_state,receiver_city,receiver_district,receiver_address";
req.PageNo = 1L;
req.PageSize = 40L;
TradesBoughtGetResponse rsp = myclient.Execute(req, sessionKey);
if (rsp != null)
{
//Console.WriteLine(rsp.Trades.Count);
//if (rsp.Trades.Count > 0)
//{
// foreach (Trade item in rsp.Trades)
// {
// Console.WriteLine(ObjectToString(item));
// }
//}
this.winGridView1.DisplayColumns = req.Fields.Replace("_", "");//对应字段的属性没有“_”字符的
this.winGridView1.DataSource = rsp.Trades;
}
