人人网登陆之C++版（MFC）

人人网需要天天登陆，才能获得持续的登录奖励，但是每次都登录啥的，感觉非常没意思，于是派生出用软件来自动登陆，这样既省时省事，又能获得奖励。

之前没有怎么接触过网络编程，搜索了下，找到参考文章 http://isouth.org/?p=297，这个是用java写的，无奈java不会，用c++写之。

那位博主 老兄已经把细节的东西都说了，登录过程非常简单，就是模拟浏览器发送请求，如果你需要更新状态，需要从返回的请求包中提取出get_check，然后在发送的时候使用这个值就ok了。

当然服务器返回的数据中，使用的是gzip编码，需要进行响应的解码才能得到数据。

别的不多说了，贴C++代码。

环境 Win7 + VS2010， MFC + zlib

 

以下是登陆代码

// 模拟FireFox4.0 登陆网页 bool CLoginDlg::OnPcWebLogin(const CString &email, // username : email const CString &password) // password: { bool ret = false; CInternetSession session; CHttpConnection* pServer; CHttpFile* pf; m_check = ""; try { CString ServerName = "www.renren.com"; INTERNET_PORT nPort = 80; //port CString suffix = "autoLogin=false&origURL=http%3A%2F%2Fwww.renren.com%2Fhome&domain=renren.com"; CString data = "email=" + email + "&password=" + password + "&" + suffix; pServer = session.GetHttpConnection(ServerName, nPort); //拼接头部 pf = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,"/PLogin.do"); pf->AddRequestHeaders("Host: www.renren.com"); pf->AddRequestHeaders("User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:2.0) Gecko/20100101 Firefox/4.0"); pf->AddRequestHeaders("Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"); pf->AddRequestHeaders("Accept-Language: zh-cn,zh;q=0.5"); pf->AddRequestHeaders("Accept-Encoding: gzip, deflate"); pf->AddRequestHeaders("Accept-Charset: GB2312,utf-8;q=0.7,*;q=0.7"); // pf->AddRequestHeaders("Keep-Alive: 115"); // pf->AddRequestHeaders("DNT: 1"); // pf->AddRequestHeaders("Connection:Keep-Alive"); pf->AddRequestHeaders("Referer: http://www.renren.com/SysHome.do"); pf->AddRequestHeaders("Content-Type: application/x-www-form-urlencoded"); pf->SendRequest(NULL, 0, data.GetBuffer(0), data.GetLength()); DWORD statusCode = 0; if(!pf->QueryInfoStatusCode(statusCode) || statusCode != HTTP_STATUS_OK) { CString e; e.Format("PC WEB Login failed, Pls Check. status code = %d/n", statusCode); throw exception(e.GetBuffer()); } DWORD ptrLen = 100 * 1024; // 以下为读取数据 LPSTR ptr = new CHAR[ptrLen]; ZeroMemory(ptr, ptrLen); DWORD len = 0, len2 = 0; do { len = pf->Read(ptr + len2, ptrLen); len2 += len; }while(len != 0); LPSTR ptr2 = new CHAR[ptrLen]; ZeroMemory(ptr2, ptrLen); // 由gzip解压 httpgzdecompress((Byte *)ptr, len2, (Byte *)ptr2, &ptrLen); delete ptr; ptr = NULL; // 寻找校验码 LPSTR checkBeginPos = strstr(ptr2, "get_check:/'"); if(checkBeginPos != NULL) { checkBeginPos += strlen("get_check:/'"); LPSTR checkEndPos = strstr(checkBeginPos, "/'"); if(checkEndPos != NULL) { *checkEndPos = '/0'; m_check = checkBeginPos; ret = true; } } delete ptr2; ptr2 = NULL; } catch(exception e) { TRACE("[ERROR]:%s/n", e.what()); } if(pf != NULL) { pf->Close(); delete pf; pf = NULL; } if(pServer != NULL) { pServer->Close(); delete pServer; pServer = NULL; } session.Close(); return ret; }

 

以下是发送状态的代码

这里面的状态要求是utf8编码，务必请自己转换，

bool CLoginDlg::OnPcWebStatus(const CString &status) // status for update { bool ret = false; if(m_check == "") { TRACE("Pls Login First!/n"); return ret; } CInternetSession session; CHttpConnection* pServer; CHttpFile* pf; CString ServerName = "status.renren.com"; INTERNET_PORT nPort = 80; //port CString data = "c=" + status + "&raw=" + status + "&isAtHome=1&publisher_form_ticket=" + m_check + "&requestToken=" + m_check; pServer = session.GetHttpConnection(ServerName,nPort); //拼接头部 pf = pServer->OpenRequest(CHttpConnection::HTTP_VERB_POST,"/doing/update.do?"); pf->AddRequestHeaders("Host: status.renren.com"); pf->AddRequestHeaders("User-Agent: Mozilla/5.0 (Windows NT 6.1; rv:2.0) Gecko/20100101 Firefox/4.0"); pf->AddRequestHeaders("Accept: text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8"); pf->AddRequestHeaders("Accept-Language: zh-cn,zh;q=0.5"); pf->AddRequestHeaders("Accept-Encoding: gzip, deflate"); pf->AddRequestHeaders("Accept-Charset: GB2312,utf-8;q=0.7,*;q=0.7"); // pf->AddRequestHeaders("Keep-Alive: 115"); // pf->AddRequestHeaders("DNT: 1"); // pf->AddRequestHeaders("Connection:Keep-Alive"); pf->AddRequestHeaders("Content-Type: application/x-www-form-urlencoded; charset=UTF-8"); pf->AddRequestHeaders("Referer: http://status.renren.com/ajaxproxy.htm"); pf->SendRequest(NULL,0,data.GetBuffer(0), data.GetLength()); ret = true; DWORD statusCode = 0; if(!pf->QueryInfoStatusCode(statusCode) || statusCode != HTTP_STATUS_OK) { TRACE("Fuck for error %d/n", statusCode); ret = false; } if(pf != NULL) { pf->Close(); delete pf; pf = NULL; } if(pServer != NULL) { pServer->Close(); delete pServer; pServer = NULL; } session.Close(); return ret; }

转换代码如下：

DWORD ucs2Len = MultiByteToWideChar(CP_ACP, 0, status.GetBuffer(0), status.GetLength(), NULL, 0); PWCHAR ucs2 = new WCHAR[ucs2Len + 1]; ZeroMemory(ucs2, (ucs2Len + 1) * sizeof(WCHAR)); MultiByteToWideChar(CP_ACP, 0, status.GetBuffer(0), status.GetLength(), ucs2, ucs2Len + 1); DWORD utf8Len = WideCharToMultiByte(CP_UTF8, 0, ucs2, ucs2Len, NULL, 0, 0, 0); PCHAR utf8 = new CHAR[utf8Len + 1]; ZeroMemory(utf8, (utf8Len + 1) * sizeof(CHAR)); WideCharToMultiByte(CP_UTF8, 0, ucs2, ucs2Len, utf8, utf8Len, 0, 0); CString newStatus = utf8; delete [] utf8; utf8 = NULL; delete [] ucs2; ucs2 = NULL;

 

最后还有最重要的是，gzip解码代码，这部分代码时参考某位大神提供的gzip的测试代码，具体是哪位大神，没有记录下来，非常的不好意思。

/* HTTP gzip decompress */ int httpgzdecompress(Byte *zdata, uLong nzdata, Byte *data, uLong *ndata) { int err = 0; z_stream d_stream = {0}; /* decompression stream */ static char dummy_head[2] = { 0x8 + 0x7 * 0x10, (((0x8 + 0x7 * 0x10) * 0x100 + 30) / 31 * 31) & 0xFF, }; d_stream.zalloc = (alloc_func)0; d_stream.zfree = (free_func)0; d_stream.opaque = (voidpf)0; d_stream.next_in = zdata; d_stream.avail_in = 0; d_stream.next_out = data; if(inflateInit2(&d_stream, 47) != Z_OK) return -1; while (d_stream.total_out < *ndata && d_stream.total_in < nzdata) { d_stream.avail_in = d_stream.avail_out = 1; /* force small buffers */ if((err = inflate(&d_stream, Z_NO_FLUSH)) == Z_STREAM_END) break; if(err != Z_OK ) { if(err == Z_DATA_ERROR) { d_stream.next_in = (Bytef*) dummy_head; d_stream.avail_in = sizeof(dummy_head); if((err = inflate(&d_stream, Z_NO_FLUSH)) != Z_OK) { return -1; } } else return -1; } } if(inflateEnd(&d_stream) != Z_OK) return -1; *ndata = d_stream.total_out; return 0; }

 

至此，当前时间2011/4/1，这段代码是可以登录校内，并且发状态，部分代码与http://isouth.org/?p=297有所差别，因为他的文章较早，校内部分协议做过修改。
