WeChat public account development complete tutorial 2

This article introduces the second complete tutorial on WeChat public account development. It has certain reference value. Now I share it with everyone. Friends in need can refer to it

because of work needs , in the past two years, there have been many projects on WeChat public accounts and mini programs. That’s why I plan to write a comprehensive production tutorial. Of course, the best tutorial is the documentation of the WeChat work platform. I'm just going to talk about the production process in my work here. I host the source code of all related articles on my own github. Welcome to follow: Address Click to open the link. Let's start our tutorial.

In the first section above, I talked about turning on the developer mode and simply obtaining the access_token and caching it, as well as simple testing. We will not do this for the time being. You need to use the parameters of this

access_token. Most of the time, we will first talk about that part of our test code and improve it: (I will introduce technologies such as Baidu Maps and Turing Robots), because the company develops We use this technology when we are working, so I will tell you about it: Start:

1. Message acceptance:

When receiving a message, WeChat will send the message according to the user's content. Divide. There are text messages, picture messages, language messages, videos, connections and other messages respectively. When a user interacts with a message on the public platform, each message will request a customized URL address. During the request process, various parameters are transmitted using the xml format. Accepting a message means obtaining relevant data from the WeChat request process.

Variable substitution used in the code uses PHP functions

sprintf

##Everyone You can check it out. Its function is nothing more than to allow variables to be replaced in sequence.

1.1. Accept text messages:

The format is as above: the code is as follows : Text template

#// Text template

$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>";

You have already seen the test results in the first section, and I will not demonstrate again

1.2

Accept picture messages:

code show as below:

// Image template

$picTpl="<xml>
                    <ToUserName><![CDATA[%s]]></ToUserName>
                    <FromUserName><![CDATA[%s]]></FromUserName>
                    <CreateTime>%s</CreateTime>
                    <MsgType><![CDATA[%s]]></MsgType>
                    <Image>
                    <MediaId><![CDATA[%s]]></MediaId>
                    </Image>
                </xml>";

The code is as follows:

The test result is:

1.3: Receptive Language Message:

The template is as follows:

The code is as follows:

}elseif($msgType=="voice"){
$contentStr ="语音消息MediaId为：".$postObj->MediaId.'具体内容为:'.$postObj->Recognition;
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time,'text', $contentStr);
echo $resultStr;
}

The result is as follows: In the above code we used one:

Attached is a picture of my test results:

1.4 Accept video messages:

The documents are as follows:

代码如下：

elseif($msgType=="video"){
$contentStr ="视频消息MediaId为：".$postObj->MediaId;
$resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time,'text', $contentStr);
echo $resultStr;
}

1.5：接受地理位置：

代码：

elseif($MsgType == 'location'){
            $contentStr = "经度为：".$postObj->Location_Y.'维度'.$postObj->Location_X.'具体地址为：'.$postObj->Label;
    $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, 'text', $contentStr);
    file_put_contents('2', $resultStr);
    echo $resultStr;
        }

结果如下：

1.6：接受链接消息：

文档如下：

代码如下：

elseif($MsgType == 'link'){
            $contentStr = '消息的标题为'.$postObj->Title;
    $resultStr = sprintf($textTpl, $fromUsername, $toUsername, $time, 'text', $contentStr);
    file_put_contents('2', $resultStr);
    echo $resultStr;
        }

结果如下：

上述几种情况都是使用的text模板接受的消息。设置微信回复的内容。接下来我们对回复内容的格式进行丰富：

2.消息的回复：

2.1回复文本消息：

格式如下：

代码如下：

2.2：回复图片的消息：

代码如下：

结果如下：

2.3回复语音的消息：

模板:

$voiceTpl="<xml>
            <ToUserName><![CDATA[%s]]></ToUserName>
            <FromUserName><![CDATA[%s]]></FromUserName>
            <CreateTime>%s</CreateTime>
            <MsgType><![CDATA[%s]]></MsgType>
            <Voice>
                <MediaId><![CDATA[%s]]></MediaId>
            </Voice>
            </xml>";

回复代码：

elseif($keyword == '语音'){
                // 关于此MediaId需要从素材库中获得，没有可以临时使用消息返回的媒体ID
                $MediaId = '3XlXZ4-r2OTNYTFAkcmpWv4QjWtwg_15B4PytQJVwOAwHpOfc38mGZTSDkDXx9po';
                $resultStr = sprintf($voiceTpl, $fromUsername, $toUsername, $time, 'voice',$MediaId);
                echo $resultStr;
            }

结果如下：

回复代码如下：

elseif($keyword=="视频"){
//关于此MediaId需要从素材库中获得，没有可以使用临时消息返回的媒体id
$MediaId="xxMyAoPbUt1u3q5Z95xrhafNzyvL3Tg08E-9Ub2m6db_Elj4XAJHr2pUOqLhREyB";
$Title = $Description ="视频还是好看的";
$resultStr = sprintf($VideoTpl, $fromUsername, $toUsername, $time, 'video', $MediaId, $Title,$Description);
echo $resultStr;

回复代码：

elseif($keyword=="图文"){
$data = array(
array('Title'=>'图文消息','Description'=>'效果好像还不错啊','PicUrl'=>'http://mmbiz.qpic.cn/mmbiz_jpg/E3TENE8JsTAqus3ic5qEtt4wl14ibBu4UaobarzTVOP18Awt83hkZM0aI9XStapN4xay6JI4lfm0H7QnKSfxQyVA/0','Url'=>'http://xiaomi.com')
);
file_put_contents('2',$data[0]['Title']);
for ($i=0; $i <count($data); $i++) {
$Articles .="<item>
                                <Title><![CDATA[{$data[$i][&#39;Title&#39;]}]]></Title>

echo $resultStr;
}

结果如下：

到此为止我们对所有的接受和回复的代码进行的书写和演示，所有的源码我会放在我的github上面，大家可以下载和关注，这一节到此为止，下一节开始使用我们的access_token开始我们的自定义菜单。
