经过几天研究网上的代码和谢灿大神的帮忙,今天终于用C#实现了微信公众号群发消息,现在整理一下。
总体思路:1.首先必须要在微信公众平台上申请一个公众号。
2.然后进行模拟登陆。(由于我对http传输原理和编程不是特别懂,在模拟登陆的地方,不是特别清楚,希望有大神指教)
3.模拟登陆后会获得一个token(令牌)和cookie。
4.因为模拟登陆后相当于就进入了微信公众平台,在这个里面就可以抓取到需要的数据,如公众好友的昵称,fakeId。其中的fakeid非常重要,因为传输数据必须要知道 对方的fakeid。
5.知道对方的fakeid就可以进行数据的发送了。
我整个项目的代码在下载里面有
不过里面还有一些小问题,希望有人继续修改和讨论!也有人说这样会被封号,所以请谨慎操作
讲一下我项目里面的主要内容
//对密码进行MD5加密
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();
}
//执行登陆操作
