PHP版微信公共平台消息主动推送,突破订阅号一天只能发送一条信息限制
微信公共平台消息主动推送接口一直是腾讯的私用接口，相信很多朋友都非常想要用到这个功能。
通过学习借鉴朋友的实现方法进行整理，实现了PHP版的微信公共平台消息主动推送。
此方法是通过模拟登录微信公共平台的方法来实现的。

代码如下：
一、登录接口部分代码：
<span>//</span><span>登录</span>
<span>private</span> <span>function</span><span> login(){
</span><span>$url</span> = 'https://mp.weixin.qq.com/cgi-bin/login?lang=zh_CN'<span>;
</span><span>$this</span>->send_data = <span>array</span><span>(
</span>'username' => <span>$this</span>->_account,
'pwd' => <span>md5</span>(<span>$this</span>->_password),
'f' => 'json'<span>
);
</span><span>$this</span>->referer = "https://mp.weixin.qq.com/"<span>;
</span><span>$this</span>->getHeader = 1<span>;
</span><span>$result</span> = <span>explode</span>("\n",<span>$this</span>->curlPost(<span>$url</span><span>));
</span><span>foreach</span> (<span>$result</span> <span>as</span> <span>$key</span> => <span>$value</span><span>) {
</span><span>$value</span> = <span>trim</span>(<span>$value</span><span>);
</span><span>if</span>(<span>preg_match</span>('/"ErrCode": (.*)/i', <span>$value</span>,<span>$match</span>)){<span>//</span><span>获取token</span>
<span>switch</span> (<span>$match</span>[1<span>]) {
</span><span>case</span> -1:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"系统错误"<span>)));
</span><span>case</span> -2:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"帐号或密码错误"<span>)));
</span><span>case</span> -3:
<span>die</span>(<span>urldecode</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=><span>urlencode</span>("密码错误"<span>)))));
</span><span>case</span> -4:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"不存在该帐户"<span>)));
</span><span>case</span> -5:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"访问受限"<span>)));
</span><span>case</span> -6:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"需要输入验证码"<span>)));
</span><span>case</span> -7:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"此帐号已绑定私人微信号，不可用于公众平台登录"<span>)));
</span><span>case</span> -8:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"邮箱已存在"<span>)));
</span><span>case</span> -32:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"验证码输入错误"<span>)));
</span><span>case</span> -200:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"因频繁提交虚假资料，该帐号被拒绝登录"<span>)));
</span><span>case</span> -94:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"请使用邮箱登陆"<span>)));
</span><span>case</span> 10:
<span>die</span>(json_encode(<span>array</span>('status'=>1,'errCode'=><span>$match</span>[1],'msg'=>"该公众会议号已经过期，无法再登录使用"<span>)));
</span><span>case</span> 0:
<span>$this</span>->userFakeid = <span>$this</span>-><span>getUserFakeid();
</span><span>break</span><span>;
}
}
</span><span>if</span>(<span>preg_match</span>('/^set-cookie:[\s]+([^=]+)=([^;]+)/i', <span>$value</span>,<span>$match</span>)){<span>//</span><span>获取cookie</span>
<span>$this</span>->cookie .=<span>$match</span>[1].'='.<span>$match</span>[2].'; '<span>;
}
</span><span>if</span>(<span>preg_match</span>('/"ErrMsg"/i', <span>$value</span>,<span>$match</span>)){<span>//</span><span>获取token</span>
<span>$this</span>->token = <span>rtrim</span>(<span>substr</span>(<span>$value</span>,<span>strrpos</span>(<span>$value</span>,'=')+1),'",'<span>);
}
}
}</span>
二、信息发送部分代码：
<span>//</span><span>单发消息</span>
<span>private</span> <span>function</span> send(<span>$fakeid</span>,<span>$content</span><span>){
</span><span>$url</span> = 'https://mp.weixin.qq.com/cgi-bin/singlesend?t=ajax-response&lang=zh_CN'<span>;
</span><span>$this</span>->send_data = <span>array</span><span>(
</span>'type' => 1,
'content' => <span>$content</span>,
'error' => 'false',
'tofakeid' => <span>$fakeid</span>,
'token' => <span>$this</span>->token,
'ajax' => 1,<span>
);
</span><span>$this</span>->referer = 'https://mp.weixin.qq.com/cgi-bin/singlemsgpage?token='.<span>$this</span>->token.'&fromfakeid='.<span>$fakeid</span>.'&msgid=&source=&count=20&t=wxm-singlechat&lang=zh_CN'<span>;
</span><span>return</span> <span>$this</span>->curlPost(<span>$url</span><span>);
}</span>
三、群发信息代码：
<span>//</span><span>群发消息</span>
<span>public</span> <span>function</span> sendMessage(<span>$content</span>='',<span>$userId</span>=''<span>) {
</span><span>if</span>(<span>is_array</span>(<span>$userId</span>) && !<span>empty</span>(<span>$userId</span><span>)){
</span><span>foreach</span>(<span>$userId</span> <span>as</span> <span>$v</span><span>){
</span><span>$json</span> = json_decode(<span>$this</span>->send(<span>$v</span>,<span>$content</span><span>));
</span><span>if</span>(<span>$json</span>->ret!=0<span>){
</span><span>$errUser</span>[] = <span>$v</span><span>;
}
}
}</span><span>else</span><span>{
</span><span>foreach</span>(<span>$this</span>->userFakeid <span>as</span> <span>$v</span><span>){
</span><span>$json</span> = json_decode(<span>$this</span>->send(<span>$v</span>['fakeid'],<span>$content</span><span>));
</span><span>if</span>(<span>$json</span>->ret!=0<span>){
</span><span>$errUser</span>[] = <span>$v</span>['fakeid'<span>];
}
}
}
</span><span>//</span><span>共发送用户数</span>
<span>$count</span> = <span>count</span>(<span>$this</span>-><span>userFakeid);
</span><span>//</span><span>发送失败用户数</span>
<span>$errCount</span> = <span>count</span>(<span>$errUser</span><span>);
</span><span>//</span><span>发送成功用户数</span>
<span>$succeCount</span> = <span>$count</span>-<span>$errCount</span><span>;
</span><span>$data</span> = <span>array</span><span>(
</span>'status'=>0,
'count'=><span>$count</span>,
'succeCount'=><span>$succeCount</span>,
'errCount'=><span>$errCount</span>,
'errUser'=><span>$errUser</span><span>
);
</span><span>return</span> json_encode(<span>$data</span><span>);
}</span>
四、获取所有用户信息代码片段：
<span>//</span><span>获取所有用户信息</span>
<span>public</span> <span>function</span><span> getAllUserInfo(){
</span><span>foreach</span>(<span>$this</span>->userFakeid <span>as</span> <span>$v</span><span>){
</span><span>$info</span>[] = <span>$this</span>->getUserInfo(<span>$v</span>['groupid'],<span>$v</span>['fakeid'<span>]);
}
</span><span>return</span> <span>$info</span><span>;
}
</span><span>//</span><span>获取用户信息</span>
<span>public</span> <span>function</span> getUserInfo(<span>$groupId</span>,<span>$fakeId</span><span>){
</span><span>$url</span> = "https://mp.weixin.qq.com/cgi-bin/getcontactinfo?t=ajax-getcontactinfo&lang=zh_CN&fakeid={<span>$fakeId</span>}"<span>;
</span><span>$this</span>->getHeader = 0<span>;
</span><span>$this</span>->referer = 'https://mp.weixin.qq.com/cgi-bin/contactmanagepage?token='.<span>$this</span>->token.'&t=wxm-friend&lang=zh_CN&pagesize='.<span>$this</span>->pageSize.'&pageidx=0&type=0&groupid='.<span>$groupId</span><span>;
</span><span>$this</span>->send_data = <span>array</span><span>(
</span>'token'=><span>$this</span>->token,
'ajax'=>1<span>
);
</span><span>$message_opt</span> = <span>$this</span>->curlPost(<span>$url</span><span>);
</span><span>return</span> <span>$message_opt</span><span>;
}
</span><span>//</span><span>获取所有用户fakeid</span>
<span>private</span> <span>function</span><span> getUserFakeid(){
</span><span>ini_set</span>('max_execution_time',600<span>);
</span><span>$pageSize</span> = 1000000<span>;
</span><span>$this</span>->referer = "https://mp.weixin.qq.com/cgi-bin/home?t=home/index&lang=zh_CN&token={<span>$_SESSION</span>['token']}"<span>;
</span><span>$url</span> = "https://mp.weixin.qq.com/cgi-bin/contactmanage?t=user/index&pagesize={<span>$pageSize</span>}&pageidx=0&type=0&groupid=0&token={<span>$this</span>->token}&lang=zh_CN"<span>;
</span><span>$user</span> = <span>$this</span>->vget(<span>$url</span><span>);
</span><span>$preg</span> = "/\"id\":(\d+),\"name\"/"<span>;
</span><span>preg_match_all</span>(<span>$preg</span>,<span>$user</span>,<span>$b</span><span>);
</span><span>$i</span> = 0<span>;
</span><span>foreach</span>(<span>$b</span>[1] <span>as</span> <span>$v</span><span>){
</span><span>$url</span> = 'https://mp.weixin.qq.com/cgi-bin/contactmanage?t=user/index&pagesize='.<span>$pageSize</span>.'&pageidx=0&type=0&groupid='.<span>$v</span>.'&token='.<span>$this</span>->token.'&lang=zh_CN'<span>;
</span><span>$user</span> = <span>$this</span>->vget(<span>$url</span><span>);
</span><span>$preg</span> = "/\"id\":(\d+),\"nick_name\"/"<span>;
</span><span>preg_match_all</span>(<span>$preg</span>,<span>$user</span>,<span>$a</span><span>);
</span><span>foreach</span>(<span>$a</span>[1] <span>as</span> <span>$vv</span><span>){
</span><span>$arr</span>[<span>$i</span>]['fakeid'] = <span>$vv</span><span>;
</span><span>$arr</span>[<span>$i</span>]['groupid'] = <span>$v</span><span>;
</span><span>$i</span>++<span>;
}
}
</span><span>return</span> <span>$arr</span><span>;
}</span>
