php - fatal error : Uncaught UnexpectedValueException: The server returned an unexpected value. 应为 "HTTP/1.1 101"，实际为 ""

Question

我是socketIO和elephantIO的新手，我正在尝试从php文件emit_test.php发送到 Node 服务器，如下所示

ini_set("display_errors",5);
include ("vendor/autoload.php");

use ElephantIO\Client;
use ElephantIO\Engine\SocketIO\Version1X;
  $version = new Version1X("http://localhost:3001");
  $client = new Client($version);

     $client->initialize();
     $client->emit("new_order", ["test"=>"test", "test1"=>"test1"]);
     $client->close();

server.js 文件

var socket = require('socket.io');
var express = require('express');
var https = require('https');
var http = require('http');
var logger = require('winston');

logger.remove(logger.transports.Console);
logger.add(logger.transports.Console, {colorize: true, timestamp: true})

logger.info('SocketIO > listening on port ');

var app = express();
var http_server = http.createServer(app).listen(3001);

function emitNewOrder(http_server){
  var io = socket.listen(http_server);

  //first listen to a connection and run the call back function
  io.sockets.on('connection', function (socket) {

    socket.on("new_order", function(data){
      console.log(data);
      //io.emit("new_order", data)
    })

  })
}

emitNewOrder(http_server);

我希望将emit_test.php 文件中的数据记录到接收器php 文件中与代码

<script>

  var socket = io.connect("http://localhost:3001");


  socket.on("new_order", function (data) {
    console.log(data);

  });
  </script>

但是在运行服务器时我收到错误:

fatal error :未捕获UnexpectedValueException:服务器返回意外值。应为“HTTP/1.1 101”，实际为“”

请问有什么帮助吗？

我也遇到了同样的问题。

我通过更改 ElephantIO 的版本修复了该问题。

在emit_test.php中我更改:

use ElephantIO\Engine\SocketIO\Version1X;
$version = new Version1X("http://localhost:3001");

到这个版本

use ElephantIO\Engine\SocketIO\Version2X;
$version = new Version2X("http://localhost:3001");
