PHP開發這門課吧,老師說期末考察就是做一個微信公衆號,所以就此入坑微信公衆平臺開發,哈哈,算是學一點新的東西吧~
本文持續更新中
準備工作
1.在微信公衆平臺 上進行註冊,我這裏註冊的是個人賬號,這裏打個小廣告,我的微信公衆號:不過時光
2.註冊的詳細過程我就不說啦。接入微信公衆號平臺進行開發需要
- 填寫服務器配置
- 驗證服務器地址的有效性
- 依據接口文檔實現業務邏輯
在進行服務器的配置前,需要對服務器進行相關的設置
我在這裏用的是騰訊雲的學生機
Ubuntu16.04 64位
首先需要安裝LAMP環境
mysql 安裝:sudo apt install mysql-server
apache 安裝:sudo apt install apache2
php 安裝:sudo apt install php
apache-php模塊安裝:sudo apt install libapache2-mod-php7.0
然後將sudo chmod 777 /var/www 使得我們可有權對www下的文件進行創建和更改
service apache2 restart
service mysql restart
在目錄下將index.php的內容改爲:
<?php
/**
* wechat php test
*/
//define your token
define("TOKEN", "weixin");//此處爲你自己設置的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;
}
}
}
?>
然後在微信公衆號平臺提交服務器配置就好啦。
