在这篇微信公众平台开发教程中，我们将介绍如何灵活的使用图文消息功能。我们将只介绍被动回复消息中的图文消息，发送客服消息及高级群发消息接口的发送的图文消息与本文介绍的图文消息的各情况基本一致。

本文分为以下四个部分：

 

一、图文消息的定义

在微信公众平台消息中，发送被动响应消息中的图文消息的XML结构如下所示。

<span><</span><span>xml</span><span>></span>
    <span><</span><span>ToUserName</span><span>></span><span><![CDATA[</span><span>toUser</span><span>]]></span><span></</span><span>ToUserName</span><span>></span>
    <span><</span><span>FromUserName</span><span>></span><span><![CDATA[</span><span>fromUser</span><span>]]></span><span></</span><span>FromUserName</span><span>></span>
    <span><</span><span>CreateTime</span><span>></span>12345678<span></</span><span>CreateTime</span><span>></span>
    <span><</span><span>MsgType</span><span>></span><span><![CDATA[</span><span>news</span><span>]]></span><span></</span><span>MsgType</span><span>></span>
    <span><</span><span>ArticleCount</span><span>></span>2<span></</span><span>ArticleCount</span><span>></span>
    <span><</span><span>Articles</span><span>></span>
        <span><</span><span>item</span><span>></span>
            <span><</span><span>Title</span><span>></span><span><![CDATA[</span><span>title1</span><span>]]></span><span></</span><span>Title</span><span>></span> 
            <span><</span><span>Description</span><span>></span><span><![CDATA[</span><span>description1</span><span>]]></span><span></</span><span>Description</span><span>></span>
            <span><</span><span>PicUrl</span><span>></span><span><![CDATA[</span><span>picurl</span><span>]]></span><span></</span><span>PicUrl</span><span>></span>
            <span><</span><span>Url</span><span>></span><span><![CDATA[</span><span>url</span><span>]]></span><span></</span><span>Url</span><span>></span>
        <span></</span><span>item</span><span>></span>
        <span><</span><span>item</span><span>></span>
            <span><</span><span>Title</span><span>></span><span><![CDATA[</span><span>title</span><span>]]></span><span></</span><span>Title</span><span>></span>
            <span><</span><span>Description</span><span>></span><span><![CDATA[</span><span>description</span><span>]]></span><span></</span><span>Description</span><span>></span>
            <span><</span><span>PicUrl</span><span>></span><span><![CDATA[</span><span>picurl</span><span>]]></span><span></</span><span>PicUrl</span><span>></span>
            <span><</span><span>Url</span><span>></span><span><![CDATA[</span><span>url</span><span>]]></span><span></</span><span>Url</span><span>></span>
        <span></</span><span>item</span><span>></span>
    <span></</span><span>Articles</span><span>></span>
<span></</span><span>xml</span><span>></span> 

其参数说明如下.

参数	是否必须	说明
ToUserName	是	接收方帐号（收到的OpenID）
FromUserName	是	开发者微信号
CreateTime	是	消息创建时间 （整型）
MsgType	是	news
ArticleCount	是	图文消息个数，限制为10条以内
Articles	是	多条图文消息信息，默认第一个item为大图,注意，如果图文数超过10，则将会无响应
Title	否	图文消息标题
Description	否	图文消息描述
PicUrl	否	图片链接，支持JPG、PNG格式，较好的效果为大图360*200，小图200*200
Url	否	点击图文消息跳转链接

从中可以知道，图文消息的类型为news，图文消息个数最大为10（注意在编辑模式中，可以设置最大条数为8）。超过10条，微信将不再响应。

多图文消息中会有大图和小图的区别，第一个item中的图片为大图，其他item中的图片为小图。

二、图文消息的实现

根据上述定义，我们定义图文消息的回复代码实现如下：

    <span>//</span><span>回复图文消息</span>
    <span>private</span> <span>function</span> transmitNews(<span>$object</span>, <span>$newsArray</span><span>)
    {
        </span><span>if</span>(!<span>is_array</span>(<span>$newsArray</span><span>)){
            </span><span>return</span><span>;
        }
        </span><span>$itemTpl</span> = "<span>    <item>
        <Title><![CDATA[%s]]></Title>
        <Description><![CDATA[%s]]></Description>
        <PicUrl><![CDATA[%s]]></PicUrl>
        <Url><![CDATA[%s]]></Url>
    </item>
</span>"<span>;
        </span><span>$item_str</span> = ""<span>;
        </span><span>foreach</span> (<span>$newsArray</span> <span>as</span> <span>$item</span><span>){
            </span><span>$item_str</span> .= <span>sprintf</span>(<span>$itemTpl</span>, <span>$item</span>['Title'], <span>$item</span>['Description'], <span>$item</span>['PicUrl'], <span>$item</span>['Url'<span>]);
        }
        </span><span>$xmlTpl</span> = "<span><xml>
<ToUserName><![CDATA[%s]]></ToUserName>
<FromUserName><![CDATA[%s]]></FromUserName>
<CreateTime>%s</CreateTime>
<MsgType><![CDATA[news]]></MsgType>
<ArticleCount>%s</ArticleCount>
<Articles>
</span><span>$item_str</span><span></Articles>
</xml></span>"<span>;

        </span><span>$result</span> = <span>sprintf</span>(<span>$xmlTpl</span>, <span>$object</span>->FromUserName, <span>$object</span>->ToUserName, <span>time</span>(), <span>count</span>(<span>$newsArray</span><span>));
        </span><span>return</span> <span>$result</span><span>;
    }</span>

上述代码中，先将各item连接形成item_str，再将item_str赋值到xml模板中，组装一个图文消息。组装时，将object中的发送、接收方互换位置，计算出图文项的个数。

而在构造图文消息并使用图文回复的代码如下所示

<span>if</span> (<span>strstr</span>(<span>$keyword</span>, "单图文"<span>)){
    </span><span>$content</span> = <span>array</span><span>();
    </span><span>$content</span>[] = <span>array</span>("Title"=>"单图文标题",  "Description"=>"单图文内容", "PicUrl"=>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
}</span><span>else</span> <span>if</span> (<span>strstr</span>(<span>$keyword</span>, "图文") || <span>strstr</span>(<span>$keyword</span>, "多图文"<span>)){
    </span><span>$content</span> = <span>array</span><span>();
    </span><span>$content</span>[] = <span>array</span>("Title"=>"多图文1标题", "Description"=>"", "PicUrl"=>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
    </span><span>$content</span>[] = <span>array</span>("Title"=>"多图文2标题", "Description"=>"", "PicUrl"=>"http://d.hiphotos.bdimg.com/wisegame/pic/item/f3529822720e0cf3ac9f1ada0846f21fbe09aaa3.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
    </span><span>$content</span>[] = <span>array</span>("Title"=>"多图文3标题", "Description"=>"", "PicUrl"=>"http://g.hiphotos.bdimg.com/wisegame/pic/item/18cb0a46f21fbe090d338acc6a600c338644adfd.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
}

</span><span>if</span>(<span>is_array</span>(<span>$content</span><span>)){
    </span><span>if</span> (<span>isset</span>(<span>$content</span>[0]['PicUrl'<span>])){
        </span><span>$result</span> = <span>$this</span>->transmitNews(<span>$object</span>, <span>$content</span><span>);
    }</span><span>else</span> <span>if</span> (<span>isset</span>(<span>$content</span>['MusicUrl'<span>])){
        </span><span>$result</span> = <span>$this</span>->transmitMusic(<span>$object</span>, <span>$content</span><span>);
    }
}</span><span>else</span><span>{
    </span><span>$result</span> = <span>$this</span>->transmitText(<span>$object</span>, <span>$content</span><span>);
}</span>

三、图文消息的类型

图文消息从item的个数上来分，可以分为单图文消息和多图文消息，其中单图文消息中item数为1，多图文消息中item数从2~10都包括。

虽然图文消息只有两种类型，但其实可以通过设置不同的参数构造出更多的展示效果。

单图文消息

单图文消息就是一个图文消息。

下面代码定义一个基本的图文消息

<span>$content</span> = <span>array</span><span>();
</span><span>$content</span>[] = <span>array</span>("Title" =>"大学英语四六级成绩查询", 
                   "Description" =>"点击图片进入", 
                   "PicUrl" =>"http://365jia.cn/uploads/13/0301/5130c2ff93618.jpg", 
                   "Url" =>"http://israel.sinaapp.com/cet/index.php?openid=".<span>$object</span>->FromUserName);

它的回复效果如图所示。其特点是标题粗体显示，内容字体则为灰色显示，如果有图片，则同时显示日期。

再看一下不定义图片和链接时的情况，代码如下

<span>$aqiArray</span> = <span>array</span><span>(); 
</span><span>$aqiArray</span>[] = <span>array</span>("Title" =><span>$cityAir</span>[0]['area']."空气质量", 
                    "Description" =>"空气质量指数(AQI)：".<span>$cityAir</span>[0]['aqi']."\n".
                                    "空气质量等级：".<span>$cityAir</span>[0]['quality']."\n".
                                    "细颗粒物(PM2.5)：".<span>$cityAir</span>[0]['pm2_5']."\n".
                                    "可吸入颗粒物(PM10)：".<span>$cityAir</span>[0]['pm10']."\n".
                                    "一氧化碳(CO)：".<span>$cityAir</span>[0]['co']."\n".
                                    "二氧化氮(NO2)：".<span>$cityAir</span>[0]['no2']."\n".
                                    "二氧化硫(SO2)：".<span>$cityAir</span>[0]['so2']."\n".
                                    "臭氧(O3)：".<span>$cityAir</span>[0]['o3']."\n".
                                    "更新时间：".<span>preg_replace</span>("/([a-zA-Z])/i", " ", <span>$cityAir</span>[0]['time_point'<span>]); 
                    </span>"PicUrl" =>"", 
                    "Url" =>"");

其效果如下所示。

可以看到，这时，由于没有图片，所以也不显示日期了，另外没有带链接，所以“查看全文”也不显示了。

多图文

多图文消息一个最大的特点就是：描述内容不会在返回中显示，所以没有必要定义描述了。

下面是一个基本的多图文消息的定义

 <span>$content</span> = <span>array</span><span>();
</span><span>$content</span>[] = <span>array</span>("Title"=>"多图文1标题", "Description"=>"", "PicUrl"=>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
</span><span>$content</span>[] = <span>array</span>("Title"=>"多图文2标题", "Description"=>"", "PicUrl"=>"http://d.hiphotos.bdimg.com/wisegame/pic/item/f3529822720e0cf3ac9f1ada0846f21fbe09aaa3.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
</span><span>$content</span>[] = <span>array</span>("Title"=>"多图文3标题", "Description"=>"", "PicUrl"=>"http://g.hiphotos.bdimg.com/wisegame/pic/item/18cb0a46f21fbe090d338acc6a600c338644adfd.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958");

其实现效果如下

如果觉得首图太大，占地方，也可以不填写。

比如这样的代码

<span>$content</span> = <span>array</span><span>(); 
</span><span>$content</span>[] = <span>array</span>("Title" =>"微信公众平台开发教程", "Description" =>"", "PicUrl" =>"", "Url" =>""<span>);
</span><span>$content</span>[] = <span>array</span>("Title" =>"【基础入门】免费\n1. 申请服务器资源\n2. 启用开发模式\n3. 消息类型详解\n4. 获取接收消息\n5. 回复不同消息", "Description" =>"", "PicUrl" =>"http://e.hiphotos.bdimg.com/wisegame/pic/item/9e1f4134970a304e1e398c62d1c8a786c9175c0a.jpg", "Url" =>"http://m.cnblogs.com/99079/3153567.html?full=1"<span>);
</span><span>$content</span>[] = <span>array</span>("Title" =>"【初级教程】双11六折促销\n1.小黄鸡机器人\n2.英语类公众账号开发", "Description" =>"", "PicUrl" =>"http://g.hiphotos.bdimg.com/wisegame/pic/item/3166d0160924ab186196512537fae6cd7b890b24.jpg", "Url" =>"http://israel.duapp.com/taobao/index.php?id=1");

其效果如下所示

$content = array(); $content[] = array("Title" =>"欢迎关注方倍工作室","Description" =>"", "PicUrl" =>"", "Url" =>""); $content[] = array("Title" =>"【1】新闻 天气 空气 股票 彩票 星座\n". "【2】快递 人品 算命 解梦 附近 苹果\n". "【3】公交 火车 汽车 航班 路况 违章\n". "【4】翻译 百科 双语 听力 成语 历史\n". "【5】团购 充值 菜谱 贺卡 景点 冬吴\n". "【6】情侣相 夫妻相 亲子相 女人味\n". "【7】相册 游戏 笑话 答题 点歌 树洞\n". "【8】微社区 四六级 华强北 世界杯\n\n". "更多精彩，即将亮相，敬请期待！";, "Description" =>"", "PicUrl" =>"", "Url" =>""); $content[] = array("Title" =>"回复对应数字查看使用方法\n发送 0 返回本菜单", "Description" =>"", "PicUrl" =>"", "Url" =>"");

其效果如下所示

四、图文消息的回复

因为图文消息有更好的视觉效果，很多朋友都想要实现图文消息的回复。主要有以下几种情况

1. 关注时回复图文消息

放到订阅事件下就行了，代码如下

    <span>//</span><span>接收事件消息</span>
    <span>private</span> <span>function</span> receiveEvent(<span>$object</span><span>)
    {
        </span><span>$content</span> = ""<span>;
        </span><span>switch</span> (<span>$object</span>-><span>Event)
        {
            </span><span>case</span> "subscribe":
                <span>$content</span> = <span>array</span><span>();
                </span><span>$content</span>[] = <span>array</span>("Title"=>"多图文1标题", "Description"=>"", "PicUrl"=>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
                </span><span>$content</span>[] = <span>array</span>("Title"=>"多图文2标题", "Description"=>"", "PicUrl"=>"http://d.hiphotos.bdimg.com/wisegame/pic/item/f3529822720e0cf3ac9f1ada0846f21fbe09aaa3.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
                </span><span>$content</span>[] = <span>array</span>("Title"=>"多图文3标题", "Description"=>"", "PicUrl"=>"http://g.hiphotos.bdimg.com/wisegame/pic/item/18cb0a46f21fbe090d338acc6a600c338644adfd.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
                </span><span>break</span><span>;
            </span><span>case</span> "unsubscribe":
                <span>$content</span> = "取消关注"<span>;
                </span><span>break</span><span>;
        }
        </span><span>if</span>(<span>is_array</span>(<span>$content</span><span>)){
            </span><span>if</span> (<span>isset</span>(<span>$content</span>[0<span>])){
                </span><span>$result</span> = <span>$this</span>->transmitNews(<span>$object</span>, <span>$content</span><span>);
            }</span><span>else</span> <span>if</span> (<span>isset</span>(<span>$content</span>['MusicUrl'<span>])){
                </span><span>$result</span> = <span>$this</span>->transmitMusic(<span>$object</span>, <span>$content</span><span>);
            }
        }</span><span>else</span><span>{
            </span><span>$result</span> = <span>$this</span>->transmitText(<span>$object</span>, <span>$content</span><span>);
        }

        </span><span>return</span> <span>$result</span><span>;
    }</span>

2. 发送关键字回复图文消息

通过判断关键字既可实现，

<span>//</span><span>接收文本消息</span>
<span>private</span> <span>function</span> receiveText(<span>$object</span><span>)
{
    </span><span>$keyword</span> = <span>trim</span>(<span>$object</span>-><span>Content);
    </span><span>if</span> (<span>strstr</span>(<span>$keyword</span>, "单图文"<span>)){
        </span><span>$content</span> = <span>array</span><span>();
        </span><span>$content</span>[] = <span>array</span>("Title"=>"单图文标题",  "Description"=>"单图文内容", "PicUrl"=>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
    }</span><span>else</span> <span>if</span> (<span>strstr</span>(<span>$keyword</span>, "图文") || <span>strstr</span>(<span>$keyword</span>, "多图文"<span>)){
        </span><span>$content</span> = <span>array</span><span>();
        </span><span>$content</span>[] = <span>array</span>("Title"=>"多图文1标题", "Description"=>"", "PicUrl"=>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
        </span><span>$content</span>[] = <span>array</span>("Title"=>"多图文2标题", "Description"=>"", "PicUrl"=>"http://d.hiphotos.bdimg.com/wisegame/pic/item/f3529822720e0cf3ac9f1ada0846f21fbe09aaa3.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
        </span><span>$content</span>[] = <span>array</span>("Title"=>"多图文3标题", "Description"=>"", "PicUrl"=>"http://g.hiphotos.bdimg.com/wisegame/pic/item/18cb0a46f21fbe090d338acc6a600c338644adfd.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
    }</span><span>else</span><span>{
        </span><span>$content</span> = <span>date</span>("Y-m-d H:i:s",<span>time</span>())."\n技术支持 方倍工作室"<span>;
    }

    </span><span>if</span>(<span>is_array</span>(<span>$content</span><span>)){
        </span><span>if</span> (<span>isset</span>(<span>$content</span>[0]['PicUrl'<span>])){
            </span><span>$result</span> = <span>$this</span>->transmitNews(<span>$object</span>, <span>$content</span><span>);
        }</span><span>else</span> <span>if</span> (<span>isset</span>(<span>$content</span>['MusicUrl'<span>])){
            </span><span>$result</span> = <span>$this</span>->transmitMusic(<span>$object</span>, <span>$content</span><span>);
        }
    }</span><span>else</span><span>{
        </span><span>$result</span> = <span>$this</span>->transmitText(<span>$object</span>, <span>$content</span><span>);
    }
}</span>

3. 点击菜单时回复图文消息

在菜单点击事件中响应即可

<span>//</span><span>接收事件消息</span>
<span>private</span> <span>function</span> receiveEvent(<span>$object</span><span>)
{
    </span><span>$content</span> = ""<span>;
    </span><span>switch</span> (<span>$object</span>-><span>Event)
    {
        </span><span>case</span> "subscribe":
            <span>$content</span> = "欢迎关注方倍工作室 "<span>;
            </span><span>break</span><span>;
        </span><span>case</span> "CLICK":
            <span>switch</span> (<span>$object</span>-><span>EventKey)
            {
                </span><span>case</span> "COMPANY":
                    <span>$content</span> = <span>array</span><span>();
                    </span><span>$content</span>[] = <span>array</span>("Title"=>"多图文1标题", "Description"=>"", "PicUrl"=>"http://discuz.comli.com/weixin/weather/icon/cartoon.jpg", "Url" =>"http://m.cnblogs.com/?u=txw1958"<span>);
                    </span><span>break</span><span>;
                </span><span>default</span>:
                    <span>$content</span> = "点击菜单：".<span>$object</span>-><span>EventKey;
                    </span><span>break</span><span>;
            }
            </span><span>break</span><span>;
    }
    </span><span>if</span>(<span>is_array</span>(<span>$content</span><span>)){
        </span><span>if</span> (<span>isset</span>(<span>$content</span>[0<span>])){
            </span><span>$result</span> = <span>$this</span>->transmitNews(<span>$object</span>, <span>$content</span><span>);
        }</span><span>else</span> <span>if</span> (<span>isset</span>(<span>$content</span>['MusicUrl'<span>])){
            </span><span>$result</span> = <span>$this</span>->transmitMusic(<span>$object</span>, <span>$content</span><span>);

4. 回复多个图文消息

由于回复消息一次只能回复一条，因此要回复多个图文消息，就需要使用其他接口。这需要已经认证的服务号才能拥有权限。

可以回复图文消息的接口有客服接口及高级群发接口，如果被动回复不够，就可使用客服接口来发送。
