在php中要实现用户登录我们一般都会到curl模拟登陆功能,下面我就基于php的curl来实现登录人人网,完整的例子希望对各位有帮助,代码如下:

<?php 
	$cookie_file = dirname(__FILE__)."/renren.cookie"; 
	 
	$login_url = 'http://passport.renren.com/PLogin.do'; 
	 
	$post_fields['email'] = '';//人人的帐号 
	$post_fields['password'] = '';//人人密码 
	$post_fields['origURL'] = 'http%3A%2F%2Fhome.renren.com%2FHome.do'; 
	$post_fields['domain'] = 'renren.com'; 
	 
	 
	$ch = curl_init($login_url); 
	curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5'); 
	curl_setopt($ch, CURLOPT_HEADER, 0); 
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
	curl_setopt($ch, CURLOPT_MAXREDIRS, 1); 
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
	curl_setopt($ch, CURLOPT_AUTOREFERER, 1); 
	curl_setopt($ch, CURLOPT_POST, 1); 
	curl_setopt($ch, CURLOPT_POSTFIELDS, $post_fields); 
	curl_setopt($ch, CURLOPT_COOKIEJAR, $cookie_file); 
	$content = curl_exec($ch); 
	curl_close($ch); 
	//匹配用户的ID 
	$send_url='http://www.renren.com/home'; 
	$ch = curl_init($send_url); 
	curl_setopt($ch, CURLOPT_HEADER, 0); 
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
	curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file); 
	curl_exec($ch); 
	$info = curl_getinfo($ch); 
	curl_close($ch); 
	//获取用户id 
	$tmp = explode('/',$info['redirect_url']); 
	$uid = array_pop($tmp); 
	unset($tmp); 
	 
	//$uid = "305115027"; 
	//获取token和rtk 
	 
	$send_url='http://www.renren.com/'.$uid; 
	$ch = curl_init($send_url); 
	curl_setopt($ch, CURLOPT_HEADER, 0); 
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
	curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file); 
	$tmp = curl_exec($ch); 
	curl_close($ch); 
	preg_match_all("/get_check:'(.*?)',get_check_x:'(.*?)',/is",$tmp,$arr); 
	$token = $arr[1][0];//1121558104 
	$rtk = $arr[2][0];//e9a9cb2 
	 
	//发布信息 
	$poststr['content'] = "这就是一个测试而已！！！"; 
	$poststr['withInfo'] = '{"wpath":[]}'; 
	$poststr['hostid:'] = $uid; 
	$poststr['privacyParams'] = '{"sourceControl": 99}'; 
	$poststr['requestToken'] = $token; 
	$poststr['_rtk'] = $rtk; 
	$poststr['channel'] = "renren"; 
	 
	$head = array( 
	   'Referer:http://shell.renren.com/ajaxproxy.htm', 
	   'X-Requested-With:XMLHttpRequest', 
	  ); 
	$ch = curl_init("http://shell.renren.com/{$uid}/status"); 
	curl_setopt($ch, CURLOPT_USERAGENT, 'Mozilla/5.0 (Windows; U; Windows NT 5.1; zh-CN; rv:1.9.1.5) Gecko/20091102 Firefox/3.5.5'); 
	curl_setopt($ch,CURLOPT_HTTPHEADER,$head); 
	curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 
	curl_setopt($ch, CURLOPT_MAXREDIRS, 1); 
	curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1); 
	curl_setopt($ch, CURLOPT_AUTOREFERER, 1); 
	curl_setopt($ch, CURLOPT_POST, 1); 
	curl_setopt($ch, CURLOPT_POSTFIELDS, $poststr); 
	curl_setopt($ch, CURLOPT_COOKIEFILE, $cookie_file); 
	$content = curl_exec($ch);//开源代码phprm.com 
	curl_close($ch); 
	$data = json_decode($content,true); 
	if($data["code"] == "0"){ 
	 echo "发布成功！"; 
	}else{ 
	 echo "shit !!!"; 
	}
