I recently developed a WeChat official account and learned some new things. I will record them here and hope to help others

<span>public function </span><span>responseMsg</span>()
    {
<span>//        $requestStr = $_REQUEST['mpxml'];  //线下测试放开
</span><span>$requestStr </span>= <span>$GLOBALS</span>[<span>"HTTP_RAW_POST_DATA"</span>]<span>;</span><span>//上线放开
</span><span>if</span>(<span>$requestStr</span>==<span>''</span>)<span>$requestStr </span>= file_get_contents(<span>"php://input"</span>)<span>;</span><span>//上线放开
</span><span>$this</span>-><span>Log</span>-><span>output</span>(<span>'req'</span><span>, </span><span>"请求报文" </span>. <span>$requestStr</span>)<span>;
</span><span>if </span>(!<span>empty</span>(<span>$requestStr</span>)) {
            <span>$postObj </span>= simplexml_load_string(<span>$requestStr</span><span>, </span><span>'SimpleXMLElement'</span><span>, </span><span><em>LIBXML_NOCDATA</em></span>)<span>;
</span><span>$fromUsername </span>= <span>$postObj</span>-><span>FromUserName</span><span>;
</span><span>$toUsername </span>= <span>$postObj</span>-><span>ToUserName</span><span>;
</span><span>$msgType </span>= <span>$postObj</span>-><span>MsgType</span><span>;
</span><span>$keyword </span>= trim(<span>$postObj</span>-><span>Content</span>)<span>;
</span><span>$arr </span>= <span>array</span>(<span>'fromUsername' </span>=> <span>$fromUsername</span><span>, </span><span>'toUsername' </span>=> <span>$toUsername</span><span>, </span><span>'msgType' </span>=> <span>$msgType</span><span>,
</span><span>'keyword' </span>=> <span>$keyword</span><span>, </span><span>'postObj' </span>=> <span>$postObj</span>)<span>;
</span><span>$responseStr </span>= <span>$this</span>-><span>controllers</span>-><span>index</span>(<span>$arr</span>)<span>;
</span><span>$this</span>-><span>Log</span>-><span>output</span>(<span>'res'</span><span>, </span><span>"应答报文" </span>. <span>$responseStr</span>)<span>;
</span><span>echo </span><span>$responseStr</span><span>;
</span>} <span>else </span>{
            <span>echo </span><span>''</span><span>;
</span><span>exit</span><span>;
</span>}
    }

Copy after login

The above is part of the code for processing messages

<span>$requestStr = $_REQUEST['mpxml']; </span>

Copy after login

Needless to say, accept the value of name as mpxml

But after the server code is online, if you write it like this, you should not be able to accept the request message (xml format) sent by WeChat from the server. Both

<span>$requestStr </span>= <span>$GLOBALS</span>[<span>"HTTP_RAW_POST_DATA"</span>]<span>;</span><span>//上线放开</span>

Copy after login

<span>$requestStr </span>= file_get_contents(<span>"php://input"</span>)<span>;</span><span>//上线放开</span>

Copy after login

can receive request messages from WeChat. The second method is recommended. It puts less pressure on memory and does not require any special php.int settings.

The above has introduced the development of WeChat public accounts---the issue of value acquisition on the WeChat request server, including aspects of it. I hope it will be helpful to friends who are interested in PHP tutorials.
