Simulation test of WeChat interface and WeChat development test code

To become a developer of a WeChat public account (subscription account or service account), you need to first verify the interface. This can be set after logging in to the WeChat https://mp.weixin.qq.com backend. But I found it troublesome, so I developed an interface class that included verification functions (as well as the function of replying to text messages and graphic messages). In fact, interface verification is useless after becoming a developer.
Upload the code, WeChat base class: weixin.class.php
class Weixin
{
public $token = '';//token
public $debug = false;//Whether the debug status is marked, so that we can record some intermediate data during debugging
public $setFlag = false;
public $msgtype = 'text'; //('text','image' ,'location')
public $msg = array();
public function __construct($token,$debug)
{
$this->token = $token;
$this ->debug = $debug;
}
//Get the message sent by the user (message content and message type)
public function getMsg()
{
$postStr = $GLOBALS[ "HTTP_RAW_POST_DATA"];
if ($this->debug)
{
$this->write_log($postStr);
}
if (!empty($postStr))
{
$this->msg = (array)simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);
$this->msgtype = strtolower($this->msg['MsgType']);
}
}
//Reply text message
public function makeText($text='')
{
$CreateTime = time();
$FuncFlag = $ this->setFlag ? 1 : 0;
$textTpl = "
msg['FromUserName']}]]>
msg['ToUserName']}]]>
{$CreateTime}

%s
";
return sprintf($textTpl,$text,$FuncFlag);
}
//Reply image and text based on array parameters Message
public function makeNews($newsData=array())
{
$CreateTime = time();
$FuncFlag = $this->setFlag ? 1 : 0;
$newTplHeader = "
msg['FromUserName']}]]>
msg['ToUserName']}]]>
{$CreateTime}

%s";
$ newTplItem = "

";
$newTplFoot = "
%s
";
$Content = '';
$itemsCount = count($newsData);
$itemsCount = $itemsCount if ($itemsCount)
{
foreach ($newsData as $key => $item)
{
if ($key {
$Content .= sprintf($newTplItem, $item['Title'],$item['Description'],$item['PicUrl'],$item['Url']);
}
}
}
$header = sprintf($newTplHeader,$newsData['content'],$itemsCount);
$footer = sprintf($newTplFoot,$FuncFlag);
return $header . $Content . $footer;
}
public function reply($data)
{
if ($this->debug)
{
$this->write_log($data);
}
echo $data;
}
public function valid()
{
if ($this->checkSignature())
{
//if( $_SERVER['REQUEST_METHOD'] =='GET' )
//{
echo $_GET['echostr'];
exit;
//}
}
else
{
write_log('Authentication failed');
exit;
}
}
private function checkSignature()
{
$signature = $_GET["signature"];
$timestamp = $_GET["timestamp"];
$nonce = $_GET["nonce"];
$tmpArr = array($this->token, $timestamp, $nonce);
sort ($tmpArr);
$tmpStr = implode( $tmpArr );
$tmpStr = sha1( $tmpStr );
if( $tmpStr == $signature )
return true;
else
return false;
}
private function write_log($log)
{
//This is where you record debugging information. Please improve it for intermediate debugging
}
}
?>

WeChat interface code: weixin.php
header("Content-Type: text/html;charset=utf-8");
include_once('weixin.class.php '); //Refer to the WeChat message processing class just defined
define("TOKEN", "itwatch"); //mmhelper
define('DEBUG', false);
$weixin = new Weixin (TOKEN, DEBUG); //Instantiation
//$weixin->valid();
$weixin->getMsg();
$type = $weixin->msgtype; //Message type
$username = $weixin->msg['FromUserName']; //Which user sent you the message? This $username is encrypted by WeChat, but each user has a one-to-one correspondence
if ($type===='text')
{
//if ($weixin->msg['Content']=='Hello2BizUser')
if ($weixin->msg['Content ']=='Hello')
{ //When a WeChat user follows your account for the first time, your public account will receive a message with the content 'Hello2BizUser'
$reply = $weixin ->makeText('Welcome to the Net Vision Prestige Public Platform');
}
else
{ //Here is the text information entered by the user
$keyword = $weixin->msg[' Content']; //User's text message content
//include_once("chaxun.php"); //Text message calls query program
//$chaxun= new chaxun(DEBUG, $keyword, $username );
//$results['items'] =$chaxun->search(); //Query code
//$reply = $weixin->makeNews($results);
$ arrayCon = array(
array(
"Title"=>"Computer Learning Network",
"Description"=>"One Hundred Thousand Whys-Computer Learning Network",
"PicUrl"=> "http://www.veryphp.cn/datas/userfiles/8bd108c8a01a892d129c52484ef97a0d/images/website13.jpg",
"Url"=>"http://www.why100000.com/"
),
array(
"Title"=>"Very PHP Learning Network",
"Description"=>"Large PHP Learning Sharing Community",
"PicUrl"=>"http://www. veryphp.cn/datas/userfiles/8bd108c8a01a892d129c52484ef97a0d/images/php01.jpg",
"Url"=>"http://www.veryphp.cn/"
)
);
$ results = $arrayCon;
$reply = $weixin->makeNews($results);
}
}
elseif ($type==='location')
{
//The user sends location information which will be processed later
}
elseif ($type===='image')
{
//The user sends an image which will be processed later
} elseif ($type===='voice')
{
//The user sends a voice that will be processed later
}
//
$weixin->reply($reply);
?>

To verify the code of the WeChat interface, use the curl function to complete. You need to open the curl extension of PHP. Just remove the comment from //$weixin->valid(); in the weixin.php file to verify it. When finished, just comment out this sentence.

//header("Content-Type : text/html;charset=utf-8");
//Prepare data
define('TOKEN', 'itwatch');//The token you define is a private key for communication
$ echostr = 'Returning this data indicates correctness. ';
$timestamp = (string)time(); //It is an integer and must be converted to a string
$nonce = 'my-nonce';
$signature = signature(TOKEN, $timestamp , $nonce);

function signature($token, $timestamp, $nonce)
{
$tmpArr = array($token, $timestamp, $nonce);
sort($tmpArr);
$tmpStr = implode($tmpArr);
$tmpStr = sha1($tmpStr);
return $tmpStr;
}
//Submit
$post_data = array(
"signature=$signature",
"timestamp=$timestamp",
"nonce=$nonce",
"echostr=$echostr"
);
$post_data = implode('&',$post_data);
$url='http://www.veryphp.cn/tools/weixin/weixin.php';
$ch = curl_init( );
curl_setopt($ch, CURLOPT_URL, $url.'?'.$post_data); //Simulate GET method
ob_start();
curl_exec($ch);
$result = ob_get_contents();
ob_end_clean();
echo $result;
?>

The above core code is two files weixin.class.php and weixin.php, which I debugged Successfully, it has been deployed on my server. If you want to test, use your mobile phone WeChat to listen to the WeChat ID: itwatch, and then enter "Hello", the string will be returned: Welcome to pay attention to the Net Vision Weixin Public Platform. Just type in and a graphic message will open.

Okay, I admit that the above code is very messy because I am very sleepy and about to go to bed. But the above code does work and is a typical principle implementation test code. I hope to provide an idea to WeChat developers. After understanding it, they can write a fully functional WeChat information background management program in combination with the database. .
If you have a WeChat service account, you can develop a menu on this basis, and then call the message reply system developed based on the above code. It's actually very simple.
This is a real network communication program. It is much more interesting than writing a corporate website, inputting data, and then retrieving it in order and displaying it in pages.
