最近自己想模拟微博登入（无验证码的情况），想分享一些歌曲。很多代码都是网上找到，现在整理一下。
1、加载我需要分享页面的数据。
var httpReq =
(HttpWebRequest)WebRequest.Create("http://pop.weibo.com/ajax_getdata?type=trend&date=" +
DateTime.Now.ToShortDateString());
httpReq.Referer = "http://pop.weibo.com/"; //指定跳转之前的地址 Referer
Message.Text += Environment.NewLine + @"加载数据开始" + Environment.NewLine;
var httpResp = (HttpWebResponse)httpReq.GetResponse();
var respStream = httpResp.GetResponseStream();
if (respStream != null)
{
var respStreamReader = new StreamReader(respStream, Encoding.UTF8);
var result = respStreamReader.ReadToEnd();
var json1 = (JObject)JsonConvert.DeserializeObject(result);
var mulist = new List<Mulist>();
foreach (var item in json1["list"]["data"])
{
var mu = new Mulist
{
songid = item["songid"].ToString(),
songname = item["songname"].ToString(),
score = int.Parse(item["score"].ToString())
};
mulist.Add(mu);
}
dataGridView1.DataSource = mulist;
Message.Text += Environment.NewLine + @"加载数据成功！" + Environment.NewLine;
}
2、分享，分享之前需要进行模拟登入，但是登入之前需要去请求一个地址，获取登入时需要的参数。
HttpWebRequest request = null;
var tim = ConvertDateTimeInt(DateTime.Now);
var baseun = Convert.ToBase64String(Encoding.Default.GetBytes(username));//请求登入之前账号为base64格式
var slGhttpurl =
"https://login.sina.com.cn/sso/prelogin.php?entry=weibo&callback=sinaSSOController.preloginCallBack&rsakt=mod&checkpin=1&client=ssologin.js(v1.4.18)&_=" +
tim + "&su=" + baseun;//登入之前会去请求这个链接获取登入需要参数
Message.Text += Environment.NewLine + @"请求登入需要参数地址开始：" + slGhttpurl + Environment.NewLine;
request = (HttpWebRequest)WebRequest.Create(slGhttpurl);
request.ContentType = "application/x-www-form-urlencoded";
request.KeepAlive = true;
request.Method = "GET";
var response = (HttpWebResponse)request.GetResponse();
var respStream = response.GetResponseStream();
var respStreamReader = new StreamReader(respStream, Encoding.UTF8);
var slGresult = respStreamReader.ReadToEnd().Substring(34).Replace(")", "").Replace("(", "");
request.GetResponse().Close();
var loginData = JsonConvert.DeserializeObject<LoginData>(slGresult);//密码加密需要用到的参数
3、请求登入地址，登入关键参数还是密码加密，我在网上找了一段js代码，结果调用可以成功登入。。js在demo里面就不放在这里了
//调用JS加密密码 这个需要添加一个dll Interop.MSScriptControl.dll
var scriptControl = new ScriptControl
{
UseSafeSubset = true,
Language = "javascript"
};
scriptControl.AddCode(GetJs());
object obj = scriptControl.Run("getpass", password, loginData.servertime, loginData.nonce, loginData.pubkey);
var pdata = obj.ToString().Trim();
Message.Text += Environment.NewLine + @"调用js密码加密成功：" + pdata + Environment.NewLine;
Message.Text += Environment.NewLine + @"登入开始：" + Environment.NewLine;
//开始登入
var lGhttpurl = "http://login.sina.com.cn/sso/login.php?client=ssologin.js(v1.4.18)&_=" +
tim;
request = (HttpWebRequest)WebRequest.Create(lGhttpurl);
var result1 = "entry=weibo&gateway=1&from=&savestate=0&useticket=1" +
"&pagerefer=http://pop.weibo.com/" +
"&vsnf=1&su=" + baseun + "&service=miniblog&servertime=" + loginData.servertime +
"&nonce=" +
loginData.nonce + "&pwencode=rsa2" +
"&rsakv=" + loginData.rsakv + "&sp= " + pdata +
"&sr=1536*864&encoding=UTF-8&cdult=2&domain=weibo.com&prelt=53&returntype=TEXT";
var bytes = Encoding.UTF8.GetBytes(result1);
request.Method = "POST";
request.KeepAlive = true;
request.CookieContainer = new CookieContainer();
request.ContentLength = bytes.Length;
request.ContentType = "application/x-www-form-urlencoded";
var reqStream1 = request.GetRequestStream();
reqStream1.Write(bytes, 0, bytes.Length);
reqStream1.Close();
request.GetResponse().Close();
Message.Text += Environment.NewLine + @"登入成功，cookie："+ request.CookieContainer.GetCookieHeader(request.RequestUri) + Environment.NewLine;
return request.CookieContainer.GetCookieHeader(request.RequestUri);//获取登入cookie，后面分享需要用到
4、获取分享的地址
public string Fxurl(string songId)
{
HttpWebRequest request2 = null;
var fXhttpurl = "http://pop.weibo.com/share?songid=" + songId;
request2 = (HttpWebRequest)WebRequest.Create(fXhttpurl);
request2.Referer = "http://pop.weibo.com/";
request2.KeepAlive = true;
request2.Host = "pop.weibo.com";
request2.CookieContainer = new CookieContainer();
var response2 = (HttpWebResponse)request2.GetResponse();
var sharereferurl = response2.ResponseUri.OriginalString;
request2.GetResponse().Close();
return sharereferurl;
}
5、开始分享，我用抓包的发现会分享的时候回去请求两个地址，如下。
/// <summary>
/// 开始分享
/// </summary>
/// <param name="sharereferurl">Referer参数</param>
/// <param name="sLGcookies">登入的cookie</param>
/// <returns></returns>
public string Fx(string sharereferurl, string sLGcookies)
{
HttpWebRequest request = null;
var tim = ConvertDateTimeInt(DateTime.Now);
var relist = sharereferurl.Split(‘&‘);
//获取分享内容拼接参数
var result4 = "content=" + relist[2].Split(‘=‘)[1] +
"&styleid=1&from=share&appkey=846367063&visible=0";
var bytes1 = Encoding.UTF8.GetBytes(result4);
//请求分享
request = (HttpWebRequest)WebRequest.Create("http://service.weibo.com/share/aj_share.php");
request.Method = "POST";
request.Referer = sharereferurl;//指定是哪个地址到的分享地址
request.ContentType = "application/x-www-form-urlencoded";
request.ContentLength = bytes1.Length;
request.Headers.Add("Cookie", sLGcookies);//添加之前获取的登入cookie
var reqStream3 = request.GetRequestStream();
reqStream3.Write(bytes1, 0, bytes1.Length);
reqStream3.Close();
request.GetResponse().Close();
request =
(HttpWebRequest)WebRequest.Create(
"http://service.weibo.com/widget/like/aj_like.php?url=&from=thirdparty&app_src=cUcI1A&_t=0&__rnd=" +
tim);
request.Method = "GET";
request.Headers.Add("Cookie", sLGcookies);
request.Referer = sharereferurl;//指定是哪个地址到的分享地址
var response4 = (HttpWebResponse)request.GetResponse();
var respStream4 = response4.GetResponseStream();
var respStreamReader4 = new StreamReader(respStream4, Encoding.UTF8);
var result6 = respStreamReader4.ReadToEnd();
var json3 = (JObject)JsonConvert.DeserializeObject(result6);//分享结果
return json3["code"].ToString();
}
这样就可以分享成功了，在此记录一下。
