微信公眾號開發---微信請求服務端取值問題

最近開發了微信公眾號,學了一些新東西,在這記錄一下,也希望能幫助到別人

<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>}
    }

以上是處理報文的部分代碼

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

這個不用說了,接受name為mpxml的值

但是在服務端程式碼上線之後，這樣寫應該是接受不到微信發送服務端的請求封包（xml格式）的。

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

或

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

都可以接受到微信的請求報文，推薦第二種方法，它給內存帶來的壓力較小，並且不需要任何特殊的php.int設置

以上就介紹了微信公眾號開發---微信請求服務端取值問題，包括了方面的內容，希望對PHP教程有興趣的朋友有所幫助。
