1、废话不多说,先上图:

2、实现代码:
using System; using System.Collections.Generic; using System.ComponentModel; using System.Data; using System.Drawing; using System.IO; using System.Linq; using System.Net; using System.Text; using System.Threading.Tasks; using System.Windows.Forms; namespace WindowsFormsApplication1 { public partial class Form1 : Form { public Form1() { InitializeComponent(); } private void button1_Click(object sender, EventArgs e) { string fno = textBox_fno.Text; //发件人的号码 string fp = textBox_fp.Text; //发件人密码 string fto = textBox_fto.Text; //收件人号码 string fm = textBox_fm.Text; //短信内容 fm = UrlEncode(fm); string url = "http://quanapi.sinaapp.com/fetion.php?u=" + fno + "&p=" + fp + "&to=" + fto + "&m=" + fm;//破解API string res = getContent(url); MessageBox.Show("短信发送成功!"); } public static string UrlEncode(string str) { StringBuilder sb = new StringBuilder(); byte[] byStr = System.Text.Encoding.Default.GetBytes(str); // for (int i = 0; i < byStr.Length; i++) { sb.Append(@"%" + Convert.ToString(byStr[i], 16)); } return (sb.ToString()); } private static string getContent(string Url) { string strResult = ""; try { HttpWebRequest request = (HttpWebRequest)WebRequest.Create(Url); //声明一个HttpWebRequest请求 request.Timeout = 30000; //设置连接超时时间 request.Headers.Set("Pragma", "no-cache"); HttpWebResponse response = (HttpWebResponse)request.GetResponse(); Stream streamReceive = response.GetResponseStream(); Encoding encoding = Encoding.GetEncoding("GB2312"); StreamReader streamReader = new StreamReader(streamReceive, encoding); strResult = streamReader.ReadToEnd(); streamReader.Close(); } catch { throw; } return strResult; } private void button2_Click(object sender, EventArgs e) { this.Close(); } } }
3、亲测通过,但首先要加飞信好友才能使用,如果您有好的方法或者其它飞信实现的方法,请给我留言,非常感谢。
