微信公众号开发分傻瓜模式和开发者模式两种，前者不要考虑调用某些接口，只要根据后台提示傻瓜式操作即可，适用于非专业开发人员。
开发模式当然就是懂程序开发的人员使用的。
下面简单说一下微信公众号开发的简易流程，新手看看会有帮助，高手请一笑而过。
1、配置服务器：
A、首先在本机建立如下结构的文件夹（这里是我自己的习惯，仅供参考）
MMPN:总目录mro message public number 微信公众号
backup:备份目录，主要用于备份php文件，每次修改时将原稿备份到里面去。
images:存放图片
includes:包含文件，包括mysql配置，smarty模板包含文件等等
menu:存放公众号菜单信息，txt文档即可
gr****zx.php:开发文件，即公众号关联的程序文件，也就是配置的url对应的文件
最后的是需求等等的文件
主程序文件：gr****zx.php
1 <?php 2 3 define("TOKEN", "aabbc_lzpt"); 4 5 //获取微信发送数据 6 $postStr = $GLOBALS["HTTP_RAW_POST_DATA"]; 7 //返回回复数据 8 if (!empty($postStr)) 9 { 10 //解析数据 11 $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA); 12 //发送消息方ID 13 $fromUsername = $postObj->FromUserName; 14 //接送消息方ID 15 $toUsername = $postObj->ToUserName; 16 //消息类型 17 $form_MsgType = $postObj->MsgType; 18 19 //事件消息 20 if($form_MsgType=="event") 21 { 22 //获取事件类型 23 $form_Event = $postObj->Event; 24 //订阅事件 25 if($form_Event=="subscribe") 26 { 27 28 //回复欢迎图文信息 29 /* 30 $resultStr = "<xml> 31 <ToUserName><![CDATA[".$fromUsername."]]></ToUserName> 32 <FromUserName><![CDATA[".$toUsername."]]></FromUserName> 33 <CreateTime>".time()."</CreateTime> 34 <MsgType><![CDATA[news]]></MsgType> 35 <ArticleCount>2</ArticleCount> 36 <Articles> 37 <item> 38 <Title><![CDATA[ 欢迎关注***微信服务平台，****]]></Title> 39 <Description><![CDATA[这是简短描述文字]]></Description> 40 <PicUrl><![CDATA[http://a.hiphotos.baidu.com/baike/c0%3Dbaike116%2C5%2C5%2C116%2C38/sign=5cae7405f21f3a294ec5dd9cf84cd754/32fa828ba61ea8d32de5a1df950a304e241f5822.jpg]]></PicUrl> 41 <Url><![CDATA[http://www.baidu.com]]></Url> </item> 42 <item> 43 <Title><![CDATA[最新动态]]></Title> 44 <Description><![CDATA[]]></Description> 45 <PicUrl><![CDATA[http://a.hiphotos.baidu.com/baike/c0%3Dbaike116%2C5%2C5%2C116%2C38/sign=5cae7405f21f3a294ec5dd9cf84cd754/32fa828ba61ea8d32de5a1df950a304e241f5822.jpg]]></PicUrl> 46 <Url><![CDATA[http://www.baidu.com]]></Url> </item> 47 48 </Articles> 49 </xml> "; 50 */ 51 //回复欢迎文字信息 52 53 $reply="您好，欢迎关注******微信公众平台"; 54 $resultStr="<xml> 55 <ToUserName><![CDATA[".$fromUsername."]]></ToUserName> 56 <FromUserName><![CDATA[".$toUsername."]]></FromUserName> 57 <CreateTime>".time()."</CreateTime> 58 <MsgType><![CDATA[text]]></MsgType> 59 <Content><![CDATA[".$reply."]]></Content> 60 </xml>"; 61 } 62 else if($form_Event=="CLICK") 63 { 64 $form_Event_Key = $postObj->EventKey; 65 if($form_Event_Key=="V3002_CONTACT") 66 { 67 /* 68 $resultStr = "<xml> 69 <ToUserName><![CDATA[".$fromUsername."]]></ToUserName> 70 <FromUserName><![CDATA[".$toUsername."]]></FromUserName> 71 <CreateTime>".time()."</CreateTime> 72 <MsgType><![CDATA[news]]></MsgType> 73 <ArticleCount>1</ArticleCount> 74 <Articles> 75 <item> 76 <Title><![CDATA[如何成为本站会员]]></Title> 77 <Description><![CDATA[本栏目介绍详细的加入流程！]]></Description> 78 <PicUrl><![CDATA[http://a.hiphotos.baidu.com/baike/c0%3Dbaike116%2C5%2C5%2C116%2C38/sign=5cae7405f21f3a294ec5dd9cf84cd754/32fa828ba61ea8d32de5a1df950a304e241f5822.jpg]]></PicUrl> 79 <Url><![CDATA[http://www.baidu.com]]></Url> 80 </item> 81 </Articles> 82 </xml> "; 83 */ 84 $reply="我们的地址：黄河东路222号\n我们的热线：0510-88888888"; 85 $resultStr="<xml> 86 <ToUserName><![CDATA[".$fromUsername."]]></ToUserName> 87 <FromUserName><![CDATA[".$toUsername."]]></FromUserName> 88 <CreateTime>".time()."</CreateTime> 89 <MsgType><![CDATA[text]]></MsgType> 90 <Content><![CDATA[".$reply."]]></Content> 91 </xml>"; 92 } 93 } 94 95 } 96 else if($form_MsgType=="location"){ 97 $lng1=$postObj->Location_X; 98 $lat1=$postObj->Location_Y; 99 $from_Location_Label=$postObj->Label;100 $reply="地理位置：";101 $reply.="纬度".$lat1."\t经度".$lng1."位置".$from_Location_Label;102 $resultStr = "<xml>103 <ToUserName><![CDATA[".$fromUsername."]]></ToUserName>104 <FromUserName><![CDATA[".$toUsername."]]></FromUserName>105 <CreateTime>".time()."</CreateTime>106 <MsgType><![CDATA[text]]></MsgType>107 <Content><![CDATA[".$reply."]]></Content>108 </xml> "; 109 110 } 111 echo $resultStr;112 exit; 113 }114 else115 {116 echo "";117 exit;118 }119 ?> 临时文件：wx_sample.php
<?php/** * wechat php test *///define your tokendefine("TOKEN", "aabbc_lzpt");$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; } }}?> 注意看两个文件开头都有代码：define("TOKEN", "aabbc_lzpt"); 这是定义token，后面的值自己设置，但是自己要记住，在微信后台配置服务器要用到它。
B、现在开始操作，首先，将gr****zx.php文件中的内容（代码），临时清空，代替以临时文件中的内容（代码），保存。将MMPN项目传到服务器，这时，主程序文件url为“http://www.****.com/MMPN/fy_hzx/grape_fy_hzx.php”这样的形式，确保路径正确，打开微信公众号后台开发者中心，点击下图中“修改配置”，将刚才的url填入相应控件
token就是刚才提到要记住的token的值，要一致。第三个“消息加密密钥”可以随机生成，然后提交。
token正确和url正确以及文件代码无误的话，会提示成功，再点启用。
C、刚才主程序文件中的代码是临时的，只是为了开通注册验证token，成功以后，可以再次清除，恢复成原来的内容。（保存好再上传到服务器）
这样服务器配置工作就结束了。
2、介绍一下主程序文件中的代码
$form_MsgType = $postObj->MsgType;
$form_MsgType消息类型，分为“事件”、“位置”(粉丝发送位置)、“文字类型”、“图片类型”等，具体可查看后台接口文档
$form_Event = $postObj->Event;
$form_Event 事件类型分为“订阅”（subscribe）（也就是点关注）、退订（unsubscribe）、“点击”（CLICK）??点击菜单，但是只针对click类型的菜单，如果是url类型的菜单，则直接打开对应的url，无须在代码中处理。
回复粉丝的内容形式一般为文字或图文两种，代码中都有。
3、菜单配置
菜单配置要知道开发者ID中的AppID（这个可以直接看到）和AppSecret（这个有可能是被隐藏的，要通过公众号管理员验证通过申请查看才能显示完整，显示完整后要及时保存记录，这样下次就不用再找管理员了）。
配置菜单前，首先要拿到access_token，它的有效期为2小时。如图点击获取access_token
然后在右下方点击“使用网页调试工具调试该接口”
输入appid和secret，点“检查问题”提交
拷贝获取到的access_token
重新选择自定义菜单：
将刚获取到的access_token 拷入
如果接口列表选择的是查询菜单，提交的结果是不存在，这就对了，因为我们还没有创建菜单呢
那么，我们就创建一个，将以下json格式代码拷入body中，提交
{ "button": [ { "name": "首页", "sub_button": [ { "type": "view", "name": "注册登录", "url": "http://www.baidu.com", "sub_button": [ ] }, { "type": "click", "name": "娱乐一刻", "key": "V1001_QUERY", "sub_button": [ ] }, { "type": "view", "name": "查看官网", "url": "http://www.baidu.com", "sub_button": [ ] } ] }, { "name": "主页", "sub_button": [ { "type": "view", "name": "注册登录", "url": "http://www.baidu.com", "sub_button": [ ] }, { "type": "click", "name": "娱乐一刻", "key": "V1001_QUERY", "sub_button": [ ] }, { "type": "view", "name": "查看官网", "url": "http://www.baidu.com", "sub_button": [ ] } ] }, { "name": "关注我们", "sub_button": [ { "type": "view", "name": "注册登录", "url": "http://www.baidu.com", "sub_button": [ ] }, { "type": "click", "name": "娱乐一刻", "key": "V1001_QUERY", "sub_button": [ ] }, { "type": "view", "name": "查看官网", "url": "http://www.baidu.com", "sub_button": [ ] } ] } ] } 提交，提示成功菜单即生成。
菜单内容中，有两个类型 （type），一个是view，这个会直接打开相应url链接；一个是click，这个就会在刚才主程序文件中寻找对应key值运行相关的代码。
格式不要弄错就行。
如果要修改菜单，先删除，再创建；一般来说，菜单更改后，公众号须重新关注才能马上看到更改效果，否则要等24小时自动更新。
