“无法POST /” | curl到nodejs（socket.io） [英] "Cannot POST /" | curl to nodejs (socket.io)

问题描述

我从另一个问题得到了以下代码在这里SO。

  function notifyNode（$ type，$ project_id，$ from_user ，$ data）{
 $ ch = curl_init（）; 
 
 curl_setopt（$ ch，CURLOPT_URL，'http://127.0.0.1'）; 
 
 curl_setopt（$ ch，CURLOPT_HEADER，0）; 
 curl_setopt（$ ch，CURLOPT_HTTPHEADER，array（'Expect：'））; $ b $ c curl_setopt（$ ch，CURLOPT_PORT，3000）; 
 curl_setopt（$ ch，CURLOPT_CONNECTTIMEOUT，2）; 
 
 curl_setopt（$ ch，CURLOPT_POST，true）; 
 
 $ pf = array（'f'=> $ type，'pid'=> $ project_id，'user_from'=> $ from_user，
'data'=& array（））; 
 
 foreach（$ data as $ k => $ v）{
 $ pf ['data'] [$ k] = $ v; 
} 
 
 curl_setopt（$ ch，CURLOPT_POSTFIELDS，http_build_query（$ pf））; 
 
 curl_exec（$ ch）; 
 curl_close（$ ch）; 
} 
 
 $ test = array（）; 
 
 array_push（$ test，first，second，third）; 
 
 notifyNode（test，moretest，user2，$ test）;我的nodejs服务器运行以下代码：
  

$ b

  app.get（'/ posts'，function（req，res）{
 
 if（res.socket.remoteAddress =='127.0.0.1'）{
 console.log（connection received）; 
 if（req.method =='POST'）{
 
 console.log （POST received）; 
 //服务器尝试向我们发送活动消息
 
 var form = new formidable.IncomingForm（）; 
 form.parse ，函数（err，fields，files）{
 
 res.writeHead（200，[[Content-Type，text / plain] 
，[Content-Length 0] 
]）; 
 res.write（''）; 
 res.end（）; 
 
 //sys.puts（sys.inspect field：fields}，true，4））; 
 
 handleServerNotice（fields）; 
}）; 
} 
} 
 
} ）;不幸的是，当我运行php脚本时，我收到一条回复消息Can not POST /...。我正在运行 socket.io在端口3000侦听，但我不知道这是否是标准过程...任何人都可以帮助我在这一个？
解决方案
第1）您的API不接受POST请求，因为app.get，您的API是在GET请求的工作，并且您从POST调用它。
 
 
 
第二）路径是/ posts 
  curl_setopt（$ ch，CURLOPT_URL， 'http://127.0.0.1'）; 
  
使用
  curl_setopt（$ ch，CURLOPT_URL，'http://127.0.0.1:3000/posts'）; 
  
 
I got the following code from another question here in SO.
function notifyNode($type, $project_id, $from_user, $data) {
    $ch = curl_init();

    curl_setopt($ch, CURLOPT_URL, 'http://127.0.0.1');

    curl_setopt($ch, CURLOPT_HEADER, 0);
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Expect:'));
    curl_setopt($ch, CURLOPT_PORT, 3000);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 2);

    curl_setopt($ch, CURLOPT_POST, true);

    $pf = array('f' => $type, 'pid' => $project_id, 'user_from' => $from_user, 
         'data' => array());

    foreach($data as $k => $v) {
        $pf['data'][$k] = $v;
    }

    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($pf));

    curl_exec($ch);
    curl_close($ch);
}

$test = array();

array_push($test,"first","second","third");

notifyNode("test","moretest","user2",$test);
with my nodejs server running the following code:
app.get('/posts', function(req, res){

  if(res.socket.remoteAddress == '127.0.0.1') {
   console.log("connection received");
    if(req.method == 'POST') {

        console.log("POST received");
        // The server is trying to send us an activity message

        var form = new formidable.IncomingForm();
        form.parse(req, function(err, fields, files) {

            res.writeHead(200, [[ "Content-Type", "text/plain"]
                    , ["Content-Length", 0]
                    ]);
            res.write('');
            res.end();

            //sys.puts(sys.inspect({fields: fields}, true, 4));

            handleServerNotice(fields);                
        });
    }
}

});
Unfortunately, when I run the php script I get an echo message "Cannot POST /"... I'm running socket.io listening in port 3000, but I don't know if this is the standard procedure... Can anyone help me in this one?
解决方案
1st ) Your API is not accepting POST request because of app.get, You API is work on GET requiest and you are calling it from POST.

2nd) The route is /posts
  curl_setopt($ch, CURLOPT_URL, 'http://127.0.0.1');
use it like
  curl_setopt($ch, CURLOPT_URL, 'http://127.0.0.1:3000/posts');
