2.wx_sample.php初始代码
<?php
/**
* wechat php test
*/
//define your token
define("token", "weixin");
$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 == $signature ){
return true;
}else{
return false;
}
}
}
?>
3.调用回复信息方法
在wx_sample.php文件中注释掉$wechatobj->valid();，在其下增加一句“$wechatobj->responsemsg();”。
<?php
/**
* wechat php test
*/
//define your token
define("token", "weixin");
$wechatobj = new wechatcallbackapitest();
//$wechatobj->valid();//接口验证
$wechatobj->responsemsg();//调用回复消息方法
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;
}
}
}
?>
4.关键词自动回复和关注回复
$keyword保存着用户微信端发来的文本信息。
官方开发者文档：https://mp.weixin.qq.com/wiki/home/index.html（消息管理-》接收消息-接收事件推送-》1.关注/取消关注事件）
关注事件与一般的文本消息有两处不同，一是msgtype值是event，二是增加了event值是subscribe。由于官方文档（最初的wx_sample.php）没有提取这个参数，需要我们自己提取。在程序中增加两个变量$msgtype和$event。
<?php
/**
* wechat php test
*/
//define your token
define("token", "weixin");
$wechatobj = new wechatcallbackapitest();
//$wechatobj->valid();//接口验证
$wechatobj->responsemsg();//调用回复消息方法
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();
$msgtype = $postobj->msgtype;//消息类型
$event = $postobj->event;//时间类型，subscribe（订阅）、unsubscribe（取消订阅）
$texttpl = "<xml>
<tousername><![cdata[%s]]></tousername>
<fromusername><![cdata[%s]]></fromusername>
<createtime>%s</createtime>
<msgtype><![cdata[%s]]></msgtype>
<content><![cdata[%s]]></content>
<funcflag>0</funcflag>
</xml>";
switch($msgtype){
case "event":
if($event=="subscribe"){
$contentstr = "hi,欢迎关注海仙日用百货!"."n"."回复数字'1',了解店铺地址."."n"."回复数字'2',了解商品种类.";
}
break;
case "text":
switch($keyword){
case "1":
$contentstr = "店铺地址："."n"."杭州市江干艮山西路233号新东升市场地下室第一排.";
break;
case "2":
$contentstr = "商品种类:"."n"."杯子、碗、棉签、水桶、垃圾桶、洗碗巾(刷)、拖把、扫把、"
."衣架、粘钩、牙签、垃圾袋、保鲜袋(膜)、剪刀、水果刀、饭盒等.";
break;
default:
$contentstr = "对不起,你的内容我会稍后回复";
}
break;
}
$msgtype = "text";
$resultstr = sprintf($texttpl, $fromusername, $tousername, $time, $msgtype, $contentstr);
echo $resultstr;
}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;
}
}
}
?>
