通過幾天研究網上的代碼和謝燦大神的幫忙,今天終於用C#實現了微信公衆號羣發消息,如今整理一下。html
整體思路:1.首先必需要在微信公衆平臺上申請一個公衆號。web
2.而後進行模擬登錄。(因爲我對http傳輸原理和編程不是特別懂,在模擬登錄的地方,不是特別清楚,但願有大神指教)ajax
3.模擬登錄後會得到一個token(令牌)和cookie。正則表達式
4.由於模擬登錄後至關於就進入了微信公衆平臺,在這個裏面就能夠抓取到須要的數據,如公衆好友的暱稱,fakeId。其中的fakeid很是重要,由於傳輸數據必需要知道 對方的fakeid。編程
5.知道對方的fakeid就能夠進行數據的發送了。json
不過裏面還有一些小問題,但願有人繼續修改和討論!也有人說這樣會被封號,因此請謹慎操做微信
講一下我項目裏面的主要內容cookie
//對密碼進行MD5加密
app
static string GetMd5Str32(string str)
{
MD5CryptoServiceProvider md5Hasher = new MD5CryptoServiceProvider();
// Convert the input string to a byte array and compute the hash.
char[] temp = str.ToCharArray();
byte[] buf = new byte[temp.Length];
for (int i = 0; i < temp.Length; i++)
{
buf[i] = (byte)temp[i];
}
byte[] data = md5Hasher.ComputeHash(buf);
// Create a new Stringbuilder to collect the bytes
// and create a string.
StringBuilder sBuilder = new StringBuilder();
// Loop through each byte of the hashed data
// and format each one as a hexadecimal string.
for (int i = 0; i < data.Length; i++)
{
sBuilder.Append(data[i].ToString("x2"));
}
// Return the hexadecimal string.
return sBuilder.ToString();
}
//執行登錄操做
