<p>因为工作的需要，这一两年对微信公众号和小程序，项目制作的比较多。所以我才打算写一篇全面的制作教程，当然了，最好的教程是微信工作平台的文档。我这里只是讲述一下我的工作中的制作流程。所有相关文章的源码，我托管在我自己的github上面，欢迎关注：地址点击打开链接。接下来开始我们的教程。</p>
<h2>1.微信与公众平台的区别：</h2>
<p>微信：即时聊天的软件，属于一对一的关系</p>
<p>微信公众平台：属于一对多的关系。</p>
<h2>2.订阅号与服务号的区别：</h2>
<p>订阅号：针对个人或媒体每天可以群发1条信息，默认不具有自定义菜单。服务器号：针对企业或银行每月可以群发4条信息，默认具有自定义菜单。运营主体是组织（比如企业、媒体、公益组织）的，可以申请服务号。运营主体是组织和个人的可以申请订阅号，但是个人不能申请服务号。</p>
<h2>3.公众平台的两种模式：</h2>
<p>1、编辑模式：直接使用微信公众平台所提供的后台操作进行用户交互。编辑模式可以使用在如下的场景：不具备开发能力的运营者，主要是进行品牌宣传、新闻媒体、自助客服的公众账号，运营初期，不需要特别多的功能，开发模式系统升级，故障等特殊情况</p>
<p>2、开发者模式：直接使用接口代码实现用户的交流</p>
<h2>4.微信公众平台前期准备：</h2>
<div>
<p>注册公众平台，拥有线上服务器</p>
</div>
<h2>5.认识一下编辑模式：</h2>
<p>原理:</p>
<p><img src="https://www.pianshen.com/images/149/db2673c7a8d4c6d260bffce5e2635b65.png"></p>
<h4>5.1消息群发：</h4>
<p><img src="https://www.pianshen.com/images/124/797256cf80923d48bd23e314a53f86ec.png"></p>
<p> </p>
<p>选择对象选择素材进行群发：</p>
<p><img src="https://www.pianshen.com/images/843/e2ef03f525896a6dc7aae5e650c64763.png"></p>
<h4>5.2：自定义菜单：</h4>
<p>启用自定义菜单，并开启：</p>
<p><img src="https://www.pianshen.com/images/765/5172fb86dd780af7b951656c986b839d.png"></p>
<p>点击查看，进入设置界面：</p>
<p><img src="https://www.pianshen.com/images/851/6942ea86077f7b9d6477d0c518f6e1b3.png"></p>
<p><img src="https://www.pianshen.com/images/945/2d2020325c606236747d1b6ce56b1e81.png"></p>
<h4>5.3自动回复：</h4>
<p><img src="https://www.pianshen.com/images/349/de8e3ec6b95a3f677178318b14355b95.png"></p>
<p>上述讲述的主要是编辑模式的使用，我想很多人应该都会使用，其实和我们平常在论坛编辑文章和帖子差不多。</p>
<h2>6.开发者模式</h2>
<p>原理：</p>
<p><img src="https://www.pianshen.com/images/407/466ae6c771754e4d15e8783480db7e4f.png"></p>
<p> </p>
<h4>6.1第一步我们要开启开发者模式：</h4>
<p>注意：在开启开发者模式之后编辑模式中部分功能不能正常使用。即开发者模式跟编辑模式存在冲突。进入设置界面：</p>
<p><img src="https://www.pianshen.com/images/740/9f761358ccefaf3f0800c3784957910c.png"></p>
<p>修改配置：</p>
<p><img src="https://www.pianshen.com/images/151/3f46cb246d123f15b2bd540d655de83f.png"></p>
<p>设置结果如下图：填写上你的服务器文件地址，token，点击提交，验证即可。如果提交并验证通过，就进入到开发者模式</p>

</div>
<p>关于上述代码中的变量来源，微信都有详细的说明，我搭建的公众号使用的是PHP7.0版本，TP5.0框架。在这里说明一下。</p>
<p>上述代码只会执行一次，开启开发者模式之后，就不会在执行，只会执行上述代码中的</p>
<div>responseMsg</div>
<p>方法。</p>
<p>我们先上传一段测试代码试试，回复文本消息，是否有回复，代码如下：</p>
<p> </p>
<div>
<div>public <em>function</em> responseMsg()</div>
<div>{</div>
<div>        //get post data, May be due to the different environments</div>
<div>        $postStr = file_get_contents('php://input');    </div>
<div>  //extract post data</div>
<div>        if (!empty($postStr)){</div>
<div>/* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection,</div>
<div>the best way is to check the validity of xml by yourself */</div>
<div>libxml_disable_entity_loader(true);</div>
<div>  $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);</div>
<div>$fromUsername = $postObj->FromUserName;</div>
<div>$toUsername = $postObj->ToUserName;</div>
<div>$keyword = trim($postObj->Content);</div>
<div>$time = time();</div>
<div>$textTpl = "<xml></div>
<div>                            <ToUserName><!]></ToUserName></div>
<div>                            <FromUserName><!]></FromUserName></div>
<div>                            <CreateTime>%s</CreateTime></div>
<div>                            <MsgType><!]></MsgType></div>
<div>                            <Content><!]></Content></div>
<div>                            <FuncFlag>0</FuncFlag></div>
<div>                            </xml>";</div>
<div>                if(!empty( $keyword ))</div>
<div>{</div>
<div>      $msgType = "text";</div>
<div>    $contentStr = "Welcome to wechat world!";</div>
<div>    $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, $msgType, $contentStr);</div>
<div>    echo $resultStr;</div>
<div>}else{</div>
<div>    echo "Input something...";</div>
<div>}</div>
<br>
<div>}else {</div>
<div>    echo "";</div>
<div>    exit;</div>
<div>}</div>
<div>}</div>

</div>
<p>结果如下：</p>
<p><img src="https://www.pianshen.com/images/967/3447316cfc7925fef8744101f8518ecf.png">，由于微信的网页授权的限制，所以我们可以申请测试账号，我这里使用的就是测试账号。上述的开启开发者模式是一样的。只需要去申请一个测试账号就好。申请的地方：</p>
<p><img src="https://www.pianshen.com/images/357/b796b339d6d6ed56d6dcd9630945358d.png"></p>
<p> </p>
<p>如果出现上述的代码，说明我们已经测试成功。接下来，我们开始获取access_token的值，这个参数对于我们来说很重要。因为</p>
<p>access_token是公众号的全局唯一接口调用凭据，公众号调用各接口时都需使用access_token。开发者需要进行妥善保存。access_token的存储至少要保留512个字符空间。access_token的有效期目前为2个小时，需定时刷新，重复获取将导致上次获取的access_token失效。access_token是身份认证其他接口基本上都需要使用该值进行验证。</p>
<h2>7.access_token获取：（可以在本地测试）</h2>
<h4>7.1查看接口说明:</h4>
<p><img src="https://www.pianshen.com/images/966/68969e8847b431852725d39f32fc6aa6.png"></p>

<h3>获取access_token方式一:</h3>
<p> </p>
<div><img src="https://www.pianshen.com/images/787/db544e28429467910893ce08721b0f3b.png"></div>

<p> </p>
<h3>获取access_token方式二：</h3>
<p> </p>
<div><img src="https://www.pianshen.com/images/315/fd07c4826bce4c74aca826cd0e516c2b.png"></div>
<p>结果如下：</p>
<p><img src="https://www.pianshen.com/images/93/794e6c1da134dfe074ca69eb9b4bf33d.png"></p>
<p>我们开始对上述的代码进行封装，因为access_token，每天只能调用2000次，所以我们要缓存起来，这样才能达到复用的效果，</p>
