夺命雷公狗---微信开发53----网页授权(oauth2.0)获取用户基本信息接口(3)实现世界留言版
前面两节课我们讲的是base型的授权了,那么现在我们开始Userinfo型授权,
先来看下我们的原理图
我们这节课来做一个 世界留言版 系统
1..首先我还是在微信测试平台那里设置好回调页面的域名
2..编写程序create_userinfourl.php,代码如下:
<?php header("Content-Type:text/html;charset=utf-8"); require_once "get_token.php"; require_once "common.php"; //公众号的appid $appid = "wxed89d8f74fa6fc51"; //回调url,也就是第三方页面 $userinfo_redirect_uri = "http://weixin.showtp.com/dream.php"; $url = "https://open.weixin.qq.com/connect/oauth2/authorize?appid={$appid}&redirect_uri={$userinfo_redirect_uri}&response_type=code&scope=snsapi_userinfo&state=STATE#wechat_redirect"; echo "您发送的值是:$url<br />"; //这里可以写得更人性化一点,通过表单post过来即可 $contentStr = $url; //因为是测试蓄意将openid写死了 $fromUsername = 'oB1_6tzeHj-KG7kL8Thmu6VcF2BM'; //因为可能会存在中文所以需要url编码 $contentStr = urlencode($contentStr); //到时候我们我发送的内容我们放到一个数组里面去了 $content_arr = array('content'=>"{$contentStr}"); //这里的意思是将来我要发送消息给这个用户 $reply_arr = array('touser'=>"{$fromUsername}",'msgtype'=>'text','text'=>$content_arr); //下一步就是将编码转成规定的json格式 $post = json_encode($reply_arr); //url解码,如果不解码他将会发来一段二进制代码 $post = urldecode($post); $url = "https://api.weixin.qq.com/cgi-bin/message/custom/send?access_token={$access_token}"; //处理好了直接发送 http_request($url,$post); echo "发送成功咯";
3...编写dream.php来接收发送过来的数据
<?php require_once "common.php"; //获取code,得到access_token和appid $code = $_GET['code']; //公众号的appid $appid = "wxed89d8f74fa6fc51"; //公众号的appsecret $appsecret = 'd4624c36b6795d1d99dcf0547af5443d'; $url = "https://api.weixin.qq.com/sns/oauth2/access_token?appid={$appid}&secret={$appsecret}&code={$code}&grant_type=authorization_code"; $res = http_request($url,null); //json解码 $res = json_decode($res); //获取openid和access_token $openid = $res->openid; $access_token = $res->access_token; //这里是请求过去拉取用户信息这和基本接口的获取是不一样的,详情可以参考手册上的第四步 $url = "https://api.weixin.qq.com/sns/userinfo?access_token={$access_token}&openid={$openid}"; $res = http_request($url,null); //他是通过json返回用户的基本信息的 $res = json_decode($res); $nickname = $res->nickname; //用户昵称 $headimgurl = $res->headimgurl; //用户头像 //因为他放回http://wx.qlogo.cn/mmopen/g3MonUZtNHkdmzicIlibx6iaFqAc56vxLSUfpb6n5WKSYVY0ChQKkiaJSgQ1dZuTOgvLLrhJbERQQ4eMsv84eavHiaiceqxibJxCfHe/46 //所以要处理以下后面的46 $small_head_imgurl = substr($headimgurl,0,-1).'132'; //小头像的地址 //通过access_token和openid获取该用户的详细信息 ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>世界留言板</title> <meta name="viewport" content="width=device-width,height=device-height,inital-scale=1.0, maximum-scale=1.0,user-scalable=no;"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <meta name="format-detection" content="telephone=no"> <link href="./jquery.mobile-1.0.min.css" rel="stylesheet" type="text/css"> <script src="./jquery-1.6.4.min.js" type="text/javascript"></script> <script src="./jquery.mobile-1.0.min.js" type="text/javascript"></script> </head> <body> <div data-role="page" id="page3"> <div data-role="header"> <h1>世界留言板</h1> </div> <div data-role="content"> <form action="post_dream.php" method="post" data-ajax="false" > <div data-role="fieldcontain"> <label for="textarea"><?php echo $nickname; ?>, 请说出您对世界心声:</label> <textarea cols="40" rows="8" name="textarea" id="textarea"></textarea> </div> <!--通过隐藏表单发送我们会用到的参数--> <input type="hidden" name="openid" value="<?php echo $openid; ?>" /> <input type="hidden" name="nickname" value="<?php echo $nickname; ?>" /> <input type="hidden" name="small_head_imgurl" value="<?php echo $small_head_imgurl; ?>" /> <div class="ui-grid-a"> <div class="ui-block-a"> <button type="submit" data-role="button" >提交心声</button> </div> <div class="ui-block-b"> <button type="reset" data-role="button">重输心声</button> </div> </div> </form> </div> </div> </body> </html>
然后我们还需要创建一个post_dream.php来接收以下dream.php传递过来的数据,但是因为我们的数据是入库的,所以我们需要先来创建一张“user_dream”表,如下所示:
我们开始写我们的post_dream.php,来进行数据的处理,代码如下:
<?php $openid = $_POST['openid']; $nickname = $_POST['nickname']; $small_head_imgurl = $_POST['small_head_imgurl']; $content = $_POST['textarea']; $conn = mysql_connect('localhost','root','root') or die('数据库链接失败'); mysql_select_db('wxdb',$conn); mysql_query('set names utf8'); $sql = "insert into user_dream (id,openid,nickname,content,headimgurl) values(null,'{$openid}','{$nickname}','{$content}','{$small_head_imgurl}')"; mysql_query($sql); ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>世界留言板</title> <meta name="viewport" content="width=device-width,height=device-height,inital-scale=1.0,maximum-scale=1.0,user-scalable=no;"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <meta name="format-detection" content="telephone=no"> <link href="./jquery.mobile-1.0.min.css" rel="stylesheet" type="text/css"> <script src="./jquery-1.6.4.min.js" type="text/javascript"></script> <script src="./jquery.mobile-1.0.min.js" type="text/javascript"></script> </head> <body> <div data-role="page" id="page3"> <div data-role="header"> <h1>世界留言板</h1> <a href="show_dream.php" data-role="button" data-icon="arrow-l">看看别人的梦想</a> </div> <div data-role="content">恭喜您! 梦想发布成功!</div> </body> </html>
这里处理完后然后写个页面然他从数据库将里面的内容遍历出来,所以我们写个show_dream.php,代码如下所示:
<?php //链接数据库 $connect = mysql_connect('localhost','root','root'); mysql_select_db('wxdb',$connect); mysql_query('set names utf8'); //分页开工咯,先取个别名counts $sql = "select count(*) as counts from user_dream"; $res = mysql_query($sql); $row = mysql_fetch_assoc($res); //这里的$row_num是总的咨询条数 $row_num = $row['counts']; //我们规定每页显示5条记录 $page_size = 5; //计算总页数 $page_count = ceil($row_num/$page_size); //接收当前用户点击的是第几页 $page_num = $_GET['page_num']; //判断$page_num是否为空,如果是空的默认给他一个1 if(empty($page_num)){ $page_num = 1; } //计算从那条记录开始获取 $begin = ($page_num-1)*$page_size; $sql = "select * from user_dream order by id desc limit {$begin},{$page_size}"; $info_res = mysql_query($sql); ?> ?> <!doctype html> <html> <head> <meta charset="utf-8"> <title>世界留言板</title> <meta name="viewport" content="width=device-width,height=device-height,inital-scale=1.0,maximum-scale=1.0,user-scalable=no;"> <meta name="apple-mobile-web-app-capable" content="yes"> <meta name="apple-mobile-web-app-status-bar-style" content="black"> <meta name="format-detection" content="telephone=no"> <link href="./jquery.mobile-1.0.min.css" rel="stylesheet" type="text/css"> <script src="./jquery-1.6.4.min.js" type="text/javascript"></script> <script src="./jquery.mobile-1.0.min.js" type="text/javascript"></script> </head> <body> <div data-role="page" id="page3"> <div data-role="header"> <h1>世界留言板</h1> </div> <div data-role="content"> <ul data-role="listview"> <?php while($row = mysql_fetch_assoc($info_res)){ ?> <li> <a href="#"><?php echo $row['nickname']; ?><br/> 对世界想说的是:<br/> <font color='red'><?php echo $row['content']; ?></font> <p class="ui-li-aside"> <img width='50px' src="<?php echo $row['headimgurl']; ?>" /> </p> </a> </li> <?php } ?> </ul> </div> <!--增加分页的按钮--> <div data-role="controlgroup" data-type="horizontal"> <?php if($page_num != 1 && $page_num > 1) { ?> <a href="/show_dream.php?page_num=<?php echo $page_num-1; ?>" data-role="button">上一页</a> <?php } ?> <?php if($page_count > $page_num) { ?> <a href="/show_dream.php?page_num=<?php echo $page_num+1; ?>" data-role="button">下一页</a> <?php } ?> </div> </div> </body> </html>
总结:
1...base授权和userinfo授权比较,我们可以发现bases型授权只能获取到用户openid,而userinfo可以获取到更多的信息,比如昵称性别头像等
2...从开发流程看,userinfo在最后还需要拉取用户信息(需要scope为snsapi_userinfo),而base型权限不需要
3...网页授权接口调用凭证的access_token,这access_token与基础支持的access_token不同
4...code作为换取access_token的票据,每次用户授权带上的code将不一样,code只能用一次,5分钟如果还没被使用则自动过期
其实oauth2.0还是有很大前景的噢,嘻嘻
