京东联盟C#接口的下载地址为:http://jos.jd.com/doc/channel.htm?id=285
下载后,默认是一个控制台程序,核心库和demo程序在一个项目中。这里我把核心库独立成了Dll项目。
接口使用流程是,初始化DefaultJdClient类,然后调用需要的接口类,传入参数,执行获取返回结果。
注意,使用前请先修改bin目录下的config.json文件,配置appkey等信息,格式如下:
{ "appkey":"11111", "appsecret":"2222", "token":"234345", "webid":"2234234", "unionid":"567567" }
1)初始化
IJdClient client = null; private void init_JDClient() { string url = "https://api.jd.com/routerjson"; this.client = new DefaultJdClient(url, dic["appkey"].ToString(), dic["appsecret"].ToString()); }
其中dic是一个Dictionary类型,保存了appkey等配置信息。
2)获取商品基本信息接口调用
private string request_goodsInfo() { ServicePromotionGoodsInfoRequest req = new ServicePromotionGoodsInfoRequest(); req.skuIds = txtGoodsID.Text;//商品ID值 ServicePromotionGoodsInfoResponse response = client.Execute(req, dic["token"], DateTime.Now.ToLocalTime()); return response.Body; }
其中dic[‘token’]是读取字典中的token值,skuIds属性是商品的ID值,这里Demo中用TextBox输入。
3)获取商品返现链接的接口调用
private string request_goodsRateUrl() { ServicePromotionGetcodeRequest req = new ServicePromotionGetcodeRequest(); req.promotionType = 7; req.materialId = "http://item.jd.com/"+txtGoodsID.Text+".html";//注意,这里是商品的落地页面,即实际链接 req.unionId = long.Parse(dic["unionid"].ToString());//联盟ID req.channel = "PC";//PC电脑端,如果是手机端就是WL req.webId = dic["webid"].ToString();//网站ID //req.extendId = "jingdong"; //req.ext1 = "jingdong"; //req.adttype = "6"; //req.protocol = 0;//1为https,其他为http //req.pid = "jingdong"; ServicePromotionGetcodeResponse response = client.Execute(req, dic["token"], DateTime.Now.ToLocalTime()); return response.Body; }
其中的materialID、unionId、webId是需要修改的,materialId是商品的实际页面。
4)解析返回的数据
返回的数据是json格式的,所以需要引入C# JSON库:Newtonsoft.Json
处理商品返现地址:
string urlinfo = request_goodsRateUrl(); string url = ""; JObject obj = JObject.Parse(urlinfo); string queryjs_result = (string)obj["jingdong_service_promotion_getcode_responce"]["queryjs_result"]; obj = JObject.Parse(queryjs_result); if ((int)obj["resultCode"] == 0) { url = (string)obj["url"]; MessageBox.Show("返现地址:"+url); }
处理商品基本信息:
string goodsinfo = request_goodsInfo(); JObject obj = JObject.Parse(goodsinfo); string getpromotioninfo_result = (string)obj["jingdong_service_promotion_goodsInfo_responce"]["getpromotioninfo_result"]; obj = JObject.Parse(getpromotioninfo_result); if ((bool)obj["sucessed"]) { obj = (JObject)obj["result"][0]; dataGridView1.Rows.Add(new object[] { "商品名称", (string)obj["goodsName"] }); dataGridView1.Rows.Add(new object[] { "商品编号", (string)obj["skuId"] }); dataGridView1.Rows.Add(new object[] { "PC比率", (string)obj["commisionRatioPc"]+"%" }); dataGridView1.Rows.Add(new object[] { "WL比率", (string)obj["commisionRatioWl"]+"%" }); dataGridView1.Rows.Add(new object[] { "PC价格", "¥"+(string)obj["unitPrice"] }); dataGridView1.Rows.Add(new object[] { "WL价格", "¥"+(string)obj["wlUnitPrice"] }); WebRequest webreq = WebRequest.Create((string)obj["imgUrl"]); WebResponse webres = webreq.GetResponse(); using(Stream stream = webres.GetResponseStream()) { pictureBox1.Image = Image.FromStream(stream); pictureBox1.Tag = url; } }
这里使用DataGridView显示商品基本信息,图片使用PictureBox显示。
