此文主要是 中国天气网和中国环境监测总站的数据抓取 打算开放全部数据抓取源代码 已在服务器上 稳定运行半个月

中国天气网 没什么 要说的 直接抓取 就可以了 代码如下
7天天气预报 一天发布3次
foreach (int areaId in weatherAreaIds)

{
string res = GetRequest(string.Format(Constant.Weather7DUrl, areaId), "isexist=1");
try
{
JsonForecast jsonForecast = JsonConvert.DeserializeObject<JsonForecast>(res);
Forecast7D forecast7D = Mapper.Map<Qtyb, Forecast7D>(jsonForecast.qtyb);
forecast7D.City = jsonForecast.city;
forecast7D.CityId = areaId;
forecast7D.Time = jsonForecast.ftime;
if (jsonForecast.ftime == weather7DLastGrabTime[areaId])
{
Thread.Sleep();
continue;
}
lock (aqiEntities)
{

中国环境检测总站
通过抓包发现用的是wcf 返回的是二进制xml文档 需要用到 一个 https://github.com/waf/WCF-Binary-Message-Inspector 把数据解析出来 同时他也是fiddler的一个插件 可以在里面直接看出
