php怎样举行微信民众号开辟

1、设置相干效劳器

（1） 以下，把本身的效劳器ip白名单设置上；

（2） 最先设置令牌，设置令牌时先需要把现成的代码放到本身的效劳器上面，代码内里包括本身的设置的令牌号码，如许才能够设置胜利。

注重：下面这个代码在设置好后，即可从效劳器上面删除代码或许把index.php改一个名字。

url必需是完全的url,比方 http://118.78.176.74/weixin/index.php

<?php
/**
 * wechat php test
 * update time: 20141008
 */

//define your token
//下面的等于你设置的token令牌

define("TOKEN", "zj123456");
$wechatObj = new wechatCallbackapiTest();
$wechatObj->valid();

class wechatCallbackapiTest
{
    public function valid()
    {
        $echoStr = $_GET["echostr"];

        //valid signature , option
        if ($this->checkSignature()) {
            echo $echoStr;
            exit;
        }
    }

    public function responseMsg()
    {
        //get post data, May be due to the different environments
        $postStr = $GLOBALS["HTTP_RAW_POST_DATA"];

        //extract post data
        if (!empty($postStr)) {

            $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
            $fromUsername = $postObj->FromUserName;
            $toUsername = $postObj->ToUserName;
            $keyword = trim($postObj->Content);
            $time = time();
            $textTpl = "<xml>
                            <ToUserName><![CDATA[%s]]></ToUserName>
                            <FromUserName><![CDATA[%s]]></FromUserName>
                            <CreateTime>%s</CreateTime>
                            <MsgType><![CDATA[%s]]></MsgType>
                            <Content><![CDATA[%s]]></Content>
                            <FuncFlag>0</FuncFlag>
                            </xml>";
            if (!empty($keyword)) {
                $msgType = "text";
                $contentStr = "Welcome to wechat world!";
                $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);
                echo $resultStr;
            } else {
                echo "Input something...";
            }

        } else {
            echo "";
            exit;
        }
    }

    private function checkSignature()
    {
        $signature = $_GET["signature"];
        $timestamp = $_GET["timestamp"];
        $nonce = $_GET["nonce"];
        $token = TOKEN;
        $tmpArr = array($token, $timestamp, $nonce);
        sort($tmpArr, SORT_STRING);
        $tmpStr = implode($tmpArr);
        $tmpStr = sha1($tmpStr);

        if ($tmpStr == $signature) {
            return true;
        } else {
            return false;
        }
    }
}

2、设置ok后，接下来就能够完成相干的微信民众号相干功用，比方说自动复兴机器人。

代码包括3部份，固然，自动复兴机器人，下面的代码有些用不到。

(1) 、index.php

<?php 
define("APPID","xxxxxxx");
define("APPSECRET","xxxxxx");
define("TOKEN","zj123456");

require("./wechat.inc.php");
$wechat = new WeChat(APPID,APPSECRET,TOKEN);
$wechat->responseMsg();
?>

(2)、wechat.inc.php

<?php

class WeChat
{
    private $_appid;
    private $_appsecret;
    private $_token;

    public function __construct($appid, $appsecret, $token)
    {
        $this->_appid = $appid;
        $this->_appsecret = $appsecret;
        $this->_token = $token;
    }

    /**

     *@curl:接见的URL

     **/
    private function _request($curl, $https = true, $method = 'get', $data = null, $headers = null)
    {
        $ch = curl_init(); //初始化
        curl_setopt($ch, CURLOPT_URL, $curl); //设置接见的URL
        // curl_setopt($ch, CURLOPT_HEADER, false); //设置不需要头信息
        curl_setopt($ch, CURLOPT_HTTPHEADER, $headers);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true); //只猎取页面内容，但不输出
        if ($https) {
            curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); //不做效劳器认证
            curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false); //不做客户端认证
        }
        if ($method == 'post') {
            curl_setopt($ch, CURLOPT_POST, true); //设置要求是POST体式格局
            curl_setopt($ch, CURLOPT_POSTFIELDS, $data); //设置POST要求的数据
        }
        $str = curl_exec($ch); //实行接见，返回效果
        curl_close($ch); //封闭curl，开释资本
        return $str;
    }

    /**
     *_getAccesstoken()：猎取access token
     **/
    private function _getAccesstoken()
    {
        $file = './accesstoken'; //用于保留access token
        if (file_exists($file)) { //推断文件是不是存在
            $content = file_get_contents($file); //猎取文件内容
            $content = json_decode($content); //json解码
            if (time() - filemtime($file) < $content->expires_in) //推断文件是不是逾期
            {
                return $content->access_token;
            }
//返回access token
        }
        $content = $this->_request("https://api.weixin.qq.com/cgi-bin/token?grant_type=client_credential&appid=" . $this->_appid . "&secret=" . $this->_appsecret); //猎取access token的json对象
        file_put_contents($file, $content); //保留json对象到指定文件
        $content = json_decode($content); //举行json解码
        return $content->access_token; //返回access token
    }

    /**

     **/
    public function _getTicket($expires_secords = 604800, $type = "temp", $scene = 1)
    {

            $data = '{"expire_seconds":' . $expires_secords . ', "action_name": "QR_SCENE", "action_info": {"scene": {"scene_id": ' . $scene . '}}}'; //暂时二维码生成所需提交数据
            return $this->_request("https://api.weixin.qq.com/cgi-bin/qrcode/create?access_token=" . $this->_getAccesstoken(), true, "post", $data, ''); //发出要求并取得ticket
        } else { //永远二维码的处置惩罚

}

注重：想要猎取用户信息必需是认证过了的定阅号或许效劳号！

综上，把如上三个文件，放到你的设置的效劳器上面，即可完成自动复兴机器人功用。
