微信公众平台消息体加解密实现，公众解密

关键字：微信公众平台消息体签名消息体加解密 encodingaeskey 安全模式

原文 http://www.cnblogs.com/txw1958/p/weixin-aes-encrypt-Decrypt.html

一、消息体加解密

微信公众平台在配置服务器时，提供了3种加解密的模式供开发者选择，即明文模式、兼容模式、安全模式,选择兼容模式和安全模式前，需在开发者中心填写消息加解密密钥EncodingAESKey。

明文模式：维持现有模式，没有适配加解密新特性，消息体明文收发，默认设置为明文模式
兼容模式：公众平台发送消息内容将同时包括明文和密文，消息包长度增加到原来的3倍左右；公众号回复明文或密文均可，不影响现有消息收发；开发者可在此模式下进行调试
安全模式（推荐）：公众平台发送消息体的内容只含有密文，公众账号回复的消息体也为密文，建议开发者在调试成功后使用此模式收发消息

什么是EncodingAESKey？

微信公众平台采用AES对称加密算法对推送给公众帐号的消息体对行加密，EncodingAESKey则是加密所用的秘钥。公众帐号用此秘钥对收到的密文消息体进行解密，回复消息体也用此秘钥加密。AES对称加密算法的原理可以参考 http://www.cnblogs.com/txw1958/p/aes.html

　　加解密的详细技术方案可以参考官方文档 http://mp.weixin.qq.com/wiki/index.php?title=%E6%8A%80%E6%9C%AF%E6%96%B9%E6%A1%88

适用公众账号类型

已认证订阅号
服务号
企业号

不能用于未认证订阅号，因为其没有appid参数

二、开发实现及数据分析

1. 配置

假设本次的开发配置中URL为

http:<span>//</span><span>www.fangbei.org/index.php</span>

接口程序中需要配置以下三项参数

<span>/*</span><span>
    方倍工作室 http://www.cnblogs.com/txw1958/
    CopyRight 2014 All Rights Reserved
</span><span>*/</span>
<span>define</span>("TOKEN", "weixin"<span>);
</span><span>define</span>("AppID", "wxbad0b45542aa0b5e"<span>);
</span><span>define</span>("EncodingAESKey", "abcdefghijklmnopqrstuvwxyz0123456789ABCDEFG"<span>);
</span><span>require_once</span>('wxBizMsgCrypt.php');

2. 加解密实现

当用户向公众账号发送消息时，微信公众账号将会在URL中带上signature、timestamp、nonce、encrypt_type、msg_signature等参数，如下所示

http:<span>//</span><span>www.fangbei.org/aes/index.php?signature=35703636de2f9df2a77a662b68e521ce17c34db4&timestamp=1414243737&nonce=1792106704&encrypt_type=aes&msg_signature=6147984331daf7a1a9eed6e0ec3ba69055256154</span>

同时向该接口推送如下XML消息，即一个已加密的消息

<span><</span><span>xml</span><span>></span>
    <span><</span><span>ToUserName</span><span>></span><span><![CDATA[</span><span>gh_680bdefc8c5d</span><span>]]></span><span></</span><span>ToUserName</span><span>></span>
    <span><</span><span>Encrypt</span><span>></span><span><![CDATA[</span><span>MNn4+jJ/VsFh2gUyKAaOJArwEVYCvVmyN0iXzNarP3O6vXzK62ft1/KG2/XPZ4y5bPWU/jfIfQxODRQ7sLkUsrDRqsWimuhIT8Eq+w4E/28m+XDAQKEOjWTQIOp1p6kNsIV1DdC3B+AtcKcKSNAeJDr7x7GHLx5DZYK09qQsYDOjP6R5NqebFjKt/NpEl/GU3gWFwG8LCtRNuIYdK5axbFSfmXbh5CZ6Bk5wSwj5fu5aS90cMAgUhGsxrxZTY562QR6c+3ydXxb+GHI5w+qA+eqJjrQqR7u5hS+1x5sEsA7vS+bZ5LYAR3+PZ243avQkGllQ+rg7a6TeSGDxxhvLw+mxxinyk88BNHkJnyK//hM1k9PuvuLAASdaud4vzRQlAmnYOslZl8CN7gjCjV41skUTZv3wwGPxvEqtm/nf5fQ=</span><span>]]></span><span></</span><span>Encrypt</span><span>></span>
<span></</span><span>xml</span><span>></span>

这时，程序需要从url中获得以下参数

<span>$timestamp</span>  = <span>$_GET</span>['timestamp'<span>];
</span><span>$nonce</span> = <span>$_GET</span>["nonce"<span>];
</span><span>$msg_signature</span>  = <span>$_GET</span>['msg_signature'<span>];
</span><span>$encrypt_type</span> = <span>$_GET</span>['encrypt_type'];

这些参数将用于加解密过程

收到消息后，先进行解密，解密部分代码如下

<span>$postStr</span> = <span>$GLOBALS</span>["HTTP_RAW_POST_DATA"<span>];
</span><span>if</span> (<span>$encrypt_type</span> == 'aes'<span>){
    </span><span>$pc</span> = <span>new</span> WXBizMsgCrypt(TOKEN, EncodingAESKey,<span> AppID);                
    </span><span>$this</span>->logger(" D \r\n".<span>$postStr</span><span>);
    </span><span>$decryptMsg</span> = "";  <span>//</span><span>解密后的明文</span>
    <span>$errCode</span> = <span>$pc</span>->DecryptMsg(<span>$msg_signature</span>, <span>$timestamp</span>, <span>$nonce</span>, <span>$postStr</span>, <span>$decryptMsg</span><span>);
    </span><span>$postStr</span> = <span>$decryptMsg</span><span>;
}</span>

解密完成后，把解密内容又返回给$postStr，这是为了保证将消息中解密后的内容和明文模式时的消息统一，方便后续处理，解密后的XML如下

<span><</span><span>xml</span><span>></span>
    <span><</span><span>ToUserName</span><span>></span><span><![CDATA[</span><span>gh_680bdefc8c5d</span><span>]]></span><span></</span><span>ToUserName</span><span>></span>
    <span><</span><span>FromUserName</span><span>></span><span><![CDATA[</span><span>oIDrpjpQ8j8mBuQ8nM26HWzNEZgg</span><span>]]></span><span></</span><span>FromUserName</span><span>></span>
    <span><</span><span>CreateTime</span><span>></span>1414243737<span></</span><span>CreateTime</span><span>></span>
    <span><</span><span>MsgType</span><span>></span><span><![CDATA[</span><span>text</span><span>]]></span><span></</span><span>MsgType</span><span>></span>
    <span><</span><span>Content</span><span>></span><span><![CDATA[</span><span>?</span><span>]]></span><span></</span><span>Content</span><span>></span>
    <span><</span><span>MsgId</span><span>></span>6074130599188426998<span></</span><span>MsgId</span><span>></span>
<span></</span><span>xml</span><span>></span>

对消息在自己的原来代码中处理，完成之后，要回复的消息如下

<span><</span><span>xml</span><span>></span>
    <span><</span><span>ToUserName</span><span>></span><span><![CDATA[</span><span>oIDrpjpQ8j8mBuQ8nM26HWzNEZgg</span><span>]]></span><span></</span><span>ToUserName</span><span>></span>
    <span><</span><span>FromUserName</span><span>></span><span><![CDATA[</span><span>gh_680bdefc8c5d</span><span>]]></span><span></</span><span>FromUserName</span><span>></span>
    <span><</span><span>CreateTime</span><span>></span>1414243733<span></</span><span>CreateTime</span><span>></span>
    <span><</span><span>MsgType</span><span>></span><span><![CDATA[</span><span>text</span><span>]]></span><span></</span><span>MsgType</span><span>></span>
    <span><</span><span>Content</span><span>></span><span><![CDATA[</span><span>2014-10-25 21:28:53

http://www.fangbei.org/</span><span>]]></span><span></</span><span>Content</span><span>></span>
<span></</span><span>xml</span><span>></span>

把上述消息进行加密，返回给微信公众账号

<span>//</span><span>加密</span>
<span>if</span> (<span>$encrypt_type</span> == 'aes'<span>){
    </span><span>$encryptMsg</span> = ''; <span>//</span><span>加密后的密文</span>
    <span>$errCode</span> = <span>$pc</span>->encryptMsg(<span>$result</span>, <span>$timeStamp</span>, <span>$nonce</span>, <span>$encryptMsg</span><span>);
    </span><span>$result</span> = <span>$encryptMsg</span><span>;
    </span><span>$this</span>->logger(" E \r\n".<span>$result</span><span>);
}</span>

加密后的内容如下

<span><</span><span>xml</span><span>></span>
    <span><</span><span>Encrypt</span><span>></span><span><![CDATA[</span><span>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</span><span>]]></span><span></</span><span>Encrypt</span><span>></span>

<span></</span><span>xml</span><span>></span>

这样，一个安全模式下的加解密消息就完成了。

微信公众平台怎发消息

微信公众平台的图文消息是这样发的：

1、先在左侧栏目管理栏目下点击素材管理项，然后在中间编辑区选择“单图文消息”或“多图文消息”进入编辑界面。（单图文消息适合一条消息一个主题，多图文消息适合一条消息多个主题）

2、进入编辑界面后添加相应的标题、封面图片、摘要（多图文消息无些项）及消息正文后保存；如果想看看编辑后的效果可选预览，输入自己的个人微信号，让消息发到自己手机上看效果。

3、进入群发功能设置好群发的对像、性别、地区后，在下面的内客选项上选择最后的”图文消息“，然后选择刚才在素材管理中编辑好并保存的图文消息，查看无误后点击下方绿色的群发按键即可发送信息。

如有不明白的欢迎追问或加我。。。
