使用Httphelper获取京东（jd.com）商品价格

站长苏飞

比如要获取这个商品的价格

http://item.jd.com/1178322.html

如果你直接请求这个页面是肯定不行的，因为他的价格是使用Ajax获取的，

网址我找到了直接提供给大家吧

http://d.360buy.com/fittingInfo/ ... mend.cbRecoFittings


看到skuid你应该就明白了，是和上面的数字是对应的，

直接访问这个页面就能提取价格

如下

"price":"119.00",这个就是，其他的大家看情况需要的就用不需要无视之

使用Httphelper提取的方法如下

[C#] 纯文本查看 复制代码

  HttpHelper http = new HttpHelper();
            HttpItem item = new HttpItem()
            {
                URL = "http://d.360buy.com/fittingInfo/get?skuId=1178322&callback=Recommend.cbRecoFittings",//URL     必需项 
                ContentType = "text/html",//返回类型    可选项有默认值 
                ResultType = ResultType.String
            };
            HttpResult result = http.GetHtml(item);
            string html = result.Html;
            string cookie = result.Cookie;

直接分析Html就行了。
