Question

我尝试进行微信api集成。通过将文件放在公用文件夹中，它可以工作。这是我的代码

<?php
traceHttp();

define('TOKEN', 'xxxxx');
$wechatObj = new wechatCallbackapiTest();
if (isset($_GET['echostr'])) {
    $wechatObj->valid();
}else{
    $wechatObj->responseMsg();
}

class wechatCallbackapiTest
{
    public function valid()
    {
        $echoStr = $_GET['echostr'];
        if($this->checkSignature()){
            echo $echoStr;
            exit;
        }
    }

    private function checkSignature()
    {
        $signature = $_GET['signature'];
        $timestamp = $_GET['timestamp'];
        $nonce = $_GET["nonce"];

        $token = TOKEN;
        $tmpArr = array($token, $timestamp, $nonce);
        sort($tmpArr);
        $tmpStr = implode( $tmpArr );
        $tmpStr = sha1( $tmpStr );

        if( $tmpStr == $signature ){
            return true;
        }else{
            return false;
        }
    }

    public function responseMsg(){  
        //get post data, May be due to the different environments  
        $postStr = file_get_contents('php://input');     

        //if (!empty($postStr)){  
        /* libxml_disable_entity_loader is to prevent XML eXternal Entity Injection, 
           the best way is to check the validity of xml by yourself */  
        //libxml_disable_entity_loader(true);  

        $postObj = simplexml_load_string($postStr, 'SimpleXMLElement', LIBXML_NOCDATA);     


        switch($postObj->MsgType){              
             case "event":   
                $this->_doEvent($postObj);   
                break;  
             case "text":   
                $this->_doText($postObj);   
                break;  
             case "image":   
                $this->_doImage($postObj);   
                break;  
             case "voice":   
                $this->_doVoice($postObj);   
                break;  
             case "music":   
                $this->_doMusic($postObj);   
                break;  
            case "location":   
                $this->_doLocation($postObj);   
                break;  
             default:   
                break;  
        }    

    }

现在，我想在控制器中创建所有此功能。但是我得到file_get_contents('php://input')的空值。我什至尝试使用$request->getContent()和$request->all()都返回空值。

任何人都可以告诉我这是什么问题？我整天都被这个问题困扰，非常感谢您的帮助。谢谢

下面是我的laravel控制器代码：

public function authenticate(Request $request) {
    $token = 'xxxxxx';
    define("TOKEN", $token);
    if(isset($_GET['echostr'])) {
        $this->valid();
    } else {
        $content = $request->all();      
    }
}

public function valid() {
    $echoStr = $_GET["echostr"];
    if($this->checkSignature()) {
        echo $echoStr;
        exit;
    }
}

private function checkSignature() {
    $signature = $_GET["signature"];
    $timestamp = $_GET["timestamp"];
    $nonce = $_GET["nonce"];

    $token = TOKEN;
    $tmpArr = array($token, $timestamp, $nonce);
    sort($tmpArr);
    $tmpStr = implode( $tmpArr );
    $tmpStr = sha1( $tmpStr );

    if($tmpStr == $signature){
        return true;
    } else {
        return false;
    }
}

结果是验证，微信api将使用GET请求，而发送msg将使用POST请求。

由于我的route.php路由仅为Route :: get，所以我的$request->getContent()返回空。

所以不是Route::get('/wechat-api', 'WController@verify');

我更改为Route::any('/wechat-api', 'WController@verify');

进行更改后，$request->getContent()最终不再为空。

无法在laravel 5.5控制器中检索file_get_contents（'php：// input'）
