首先准备一个api.php文件 这个文件可以再微信开发平台网站手册里面下载到
需要配置的是token
微信测试地址
https://mp.weixin.qq.com/debug/
<?php /** * wechat php test */ //define your token define("TOKEN", "这里写你的token"); $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)){ /* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection, the best way is to check the validity of xml by yourself */ libxml_disable_entity_loader(true); $postObj = simplexml_load_string($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() { // you must define TOKEN by yourself if (!defined("TOKEN")) { throw new Exception('TOKEN is not defined!'); } $signature = $_GET["signature"]; $timestamp = $_GET["timestamp"]; $nonce = $_GET["nonce"]; $token = TOKEN; $tmpArr = array($token, $timestamp, $nonce); // use SORT_STRING rule sort($tmpArr, SORT_STRING); $tmpStr = implode( $tmpArr ); $tmpStr = sha1( $tmpStr ); if( $tmpStr == $signature ){ return true; }else{ return false; } } } ?>然后配置你的服务器
输入你设置的token 配置完成就可以进行开发了
首先需要的几个参数
首先你会拥有一个appID和appsecret
然后你需要设置你的接口配置
这里的url填写你的最开始的那个文件路径
token可以随便写
token填到第一个文件里面去
然后保存提交
提交之后便可以开始开发了 这里附上最基本的获取用户头像和用户名的代码
新建一个文件weixin.php
以下有三个参数需要填写
appid填写你的appid
appsecret填写你的appsecret
redirect_uri填写你的回调域名
<meta charset="utf-8"> <?php $appid='填写你的appid'; $appsecret='填写你的appsecret'; $redirect_uri='填写你的域名地址/weixin.php'; $code=isset($_GET['code'])?$_GET['code']:''; $url='https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$appid.'&secret='.$appsecret.'&code='.$code.'&grant_type=authorization_code'; //获取html代码 function getSslPage($url) { $ch = curl_init(); curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, FALSE); curl_setopt($ch, CURLOPT_HEADER, false); curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_REFERER, $url); curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE); $result = curl_exec($ch); curl_close($ch); return $result; } $user=getSslPage($url); // $user=file_get_contents($url); // echo $user;exit; $access_token=explode('access_token":"',$user)[1]; $access_token=explode('"',$user)[0];//access_token $openid=explode('"openid":"',$user)[1]; $openid=explode('"',$openid)[0];//openid $refresh_token=explode('refresh_token":"',$user)[1]; $refresh_token=explode('"',$refresh_token)[0];//refresh_token $aa=json($user); echo $aa->access_token; // $user_info_url='https://api.weixin.qq.com/sns/oauth2/access_token?appid='.$appid.'&secret='.$appsecret.'&code='.$code.'&grant_type=authorization_code'; $use_url='https://api.weixin.qq.com/sns/oauth2/refresh_token?appid='.$appid.'&grant_type=refresh_token&refresh_token='.$refresh_token; $user_cont=getSslPage($use_url); // echo $user_cont;exit; $access_token=explode('access_token":"',$user_cont)[1]; $access_token=explode('"',$access_token)[0];//access_token $openid=explode('"openid":"',$user_cont)[1]; $openid=explode('"',$openid)[0];//openid $refresh_token=explode('refresh_token":"',$user_cont)[1]; $refresh_token=explode('"',$refresh_token)[0];//refresh_token $user_info='https://api.weixin.qq.com/sns/userinfo?access_token='.$access_token.'&openid='.$openid.'&lang=zh_CN;'; $text=getSslPage($user_info); $arr=json_decode($text,true); echo '网名：'.$arr['nickname'].'</br>'; echo '头像：<img src='.$arr['headimgurl'].'></br>';然后微信访问这个weixin.php文件就能看到你的头像和网名了
