有空就分析了下百度的登陸協(xié)議。

大家看代碼：

size_t CURLWriteDataCallbak(char *data, size_t size, size_t nmemb, string *writerData) {if (writerData == NULL) return 0; size_t len = size*nmemb; writerData->append(data, len); return len; }void MsgCookie(CURL *curl) {CURLcode cookieRes;struct curl_slist *cookies;struct curl_slist *nc;int i;cookieRes = curl_easy_getinfo(curl, CURLINFO_COOKIELIST, &cookies);if (cookieRes != CURLE_OK) {::MessageBox(NULL,"err get cookie!","",0);return ;}nc = cookies, i = 1;CStdioFile f;//f.Open("c:\\cookie.txt",CFile::modeCreate|// CFile::modeNoTruncate|CFile::modeWrite);while (nc){::MessageBox(NULL,nc->data,"",0);//f.WriteString(nc->data);//f.WriteString("\n");nc = nc->next;i++;}//f.Close();::MessageBox(NULL,"ok","",0);if (i == 1){::MessageBox(NULL,"read cookie err\n","",0);}curl_slist_free_all(cookies);} //主要思路是，先登陸百度首頁，然后登陸百度空間，為啥不直接登陸百度空間等會大家看下面（當然大家可以登陸百度首頁后可以直接訪問百度其他的產(chǎn)品！！嘿嘿）

在此我分享下我的那個百度空間登錄代碼，沒有寫完，最主要的是最后一步我不會js，最后百度空間的跨域檢測！！如果有大牛知道請告訴小弟！
