一步一步做，肯定能成功 HttpHelper类请从网络上搜索

string postData = getPostData();

HttpHelper ht = new HttpHelper();

HttpItem item = new HttpItem()

{

URL = "https://account.xiaomi.com/pass/serviceLoginAuth2",

Method = "POST",

Postdata = postData,

CookieContainer = new System.Net.CookieContainer(),

ContentType = new MiLoginHttpHelper().contentType,

};

string html = ht.GetHtml(item).Html;

方法：getPostData()

private string getPostData()

{

string name = txtUName.Text.Trim();

string pwd = txtPwd.Text.Trim();

PostParaPair model = new PostParaPair();

model.Add(new PostParaPair() { Key = "_sign", Value = "R4cRs0JL2JfHHaPenjPG2c3Foa4=" });

model.Add(new PostParaPair() { Key = "callback", Value = "https://account.xiaomi.com/sts?sign=6aRtWvCpNNuCwNpKtdu9CEEJOL8%3D&followup=https%3A%2F%2Faccount.xiaomi.com%2Fpass%2FuserInfo&s });

model.Add(new PostParaPair() { Key = "qs", Value = "%3Fcallback%3Dhttps%253A%252F%252Faccount.xiaomi.com%252Fsts%253Fsign%253D6aRtWvCpNNuCwNpKtdu9CEEJOL8%25253D%2526followup%253Dhttps%25253A%25252F%25252Faccount.xiaomi.com%25252Fpass%25252FuserInfo%2526sid%253Dpassport%26sid%3Dpassport" });

model.Add(new PostParaPair() { Key = "pwd", Value = pwd });

model.Add(new PostParaPair() { Key = "serviceParam", Value = "{\"checkSafePhone\":false}" });

model.Add(new PostParaPair() { Key = "sid", Value = "passport" });

model.Add(new PostParaPair() { Key = "user", Value = name });

return model.ToString();

}

类PostParaPair：

public class PostParaPair

{

List<PostParaPair> paraList = new List<PostParaPair>();

public string Key { get; set; }

public string Value { get; set; }

public void Add(PostParaPair para)

{

paraList.Add(para);

}

public override string ToString()

{

string reString = "";

if (paraList.Count != 0)

{

foreach (PostParaPair item in paraList)

{

reString += string.Format("&{0}={1}", item.Key, CommonMethod.GetUrlEncode(item.Value));

}

}

return reString.TrimStart('&');

}

}

CommonMethod.GetUrlEncode：方法

public static string GetUrlEncode(string content)

{

return System.Web.HttpUtility.UrlEncode(content, System.Text.Encoding.UTF8);

}
