C# 新浪微博群发器

通过新浪微博api群发微博，使用了sina提供的sdk，并对其进行小改，跳过了oauth页面认证。这个sdk用起来挺方便的。下面介绍实现方法，给有这方面需要的一个参考。

由于跳过了oauth页面认证，需要发送一次用户密码，不够安全，大家应该酌情使用。

我小改的sdk下载地址，将下载下来的文件夹复制到项目中：https://files.cnblogs.com/fmnisme/sinaApi.rar

绕过oauth页面认证的方法使用了博客园akita 的方法，在此感谢，关于该方法的博客：http://www.cnblogs.com/btxakita/archive/2011/05/24/2055767.html

新浪对api访问次数有限制：

也就是说：每个账号每小时最多发30条微博。。。。

skd使用方法：

首先修改SDK中GlobalInfo类的appkey,appSecret为你在sina申请到的appKey，appSecret；

var httpRequest = HttpRequestFactory.CreateHttpRequest(Method.GET) as HttpGet;
//因为群发博客，所以用数组存放了用户信息，x代表数组下标。
                httpRequest.GetRequestToken();
                string url = httpRequest.GetAuthorizationUrl();
                GlobalInfo.requestTokens[x] = httpRequest.Token;
                GlobalInfo.requesTokenSecrets[x] = httpRequest.TokenSecret;
                httpRequest.GetVerifier(“用户名[x]”,“密码[x]”x); 
                httpRequest.GetAccessToken();
                GlobalInfo.requestTokens[x] = httpRequest.Token;
                GlobalInfo.requesTokenSecrets[x] = httpRequest.TokenSecret;
                var sendUrl = "http://api.t.sina.com.cn/statuses/update.xml?";
                httpRequest2.Request(sendUrl, "status=" + HttpUtility.UrlEncode(“微博内容”));

下面贴出代码：

using:

using System;
using System.Collections.Generic;
using System.Windows.Forms;
using System.IO;
using LeoShi.Soft.OpenSinaAPI;
using System.Web;
using System.Threading;

读取配置文件并获取相应的accessToken，配置文件的格式为：username&password，每个这样的占一行，使用记事本写就行了。

private void btn_readIni_Click(object sender, EventArgs e)
        {
            if (openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                txt_filePath.Text = openFileDialog1.FileName;
            }

            if (txt_filePath.Text != "")
            {
                FileStream fs = new FileStream(txt_filePath.Text, FileMode.Open, FileAccess.Read);
                StreamReader sr = new StreamReader(fs);
                while(!sr.EndOfStream)
                {
                    string str = sr.ReadLine();;
                    if (str == "")
                        continue;
                    string[] strArr = str.Split('&');
                    userInfoList.Add(new string[2] {strArr[0].Trim(),strArr[1].Trim()});
                }
                sr.Close();
                fs.Close();
            }
            btn_send.Enabled = false;
            initSina();
            btn_send.Enabled = true;
            lb_status.Text = "成功连接微博，初始化完成";
        }

        private void initSina()
        {
            for (int x = 0; x < userInfoList.Count; x++)
            {
                if (userInfoList[x][0]=="")
                    break;
                var httpRequest = HttpRequestFactory.CreateHttpRequest(Method.GET) as HttpGet;
                httpRequest.GetRequestToken();
                string url = httpRequest.GetAuthorizationUrl();
                GlobalInfo.requestTokens[x] = httpRequest.Token;
                GlobalInfo.requesTokenSecrets[x] = httpRequest.TokenSecret;
                httpRequest.GetVerifier(userInfoList[x][ 0], userInfoList[x][ 1],x);
                httpRequest.GetAccessToken();
                GlobalInfo.requestTokens[x] = httpRequest.Token;
                GlobalInfo.requesTokenSecrets[x] = httpRequest.TokenSecret;
            }
        }

                times++;
                for (int x = 0; x < userInfoList.Count; x++)
                {
                    lb_status.Text = userInfoList[x][0] + " " + x.ToString() + "/" + userInfoList.Count;
                    var httpRequest2 = HttpRequestFactory.CreateHttpRequest(Method.POST);
                    httpRequest2.Token = GlobalInfo.requestTokens[x];
                    httpRequest2.TokenSecret = GlobalInfo.requesTokenSecrets[x];
                    var sendUrl = "http://api.t.sina.com.cn/statuses/update.xml?";
                    httpRequest2.Request(sendUrl, "status=" + HttpUtility.UrlEncode(txt_weibo.Text + "  " + times.ToString()));
                    Thread.Sleep(150);
