致命错误：未捕获的意外值异常：服务器返回意外值。预期"HTTP/1.1 101"，有" "

Question

我是socketIO和elephantIO的新手，正在尝试从php文件向节点服务器发出emit_test.php如波纹管

ini_set("display_errors",5);
include ("vendor/autoload.php");
use ElephantIOClient;
use ElephantIOEngineSocketIOVersion1X;
  $version = new Version1X("http://localhost:3001");
  $client = new Client($version);
     $client->initialize();
     $client->emit("new_order", ["test"=>"test", "test1"=>"test1"]);
     $client->close();

服务器.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emit_test.php文件中的数据记录在接收式 PHP 文件中 用代码

<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出现错误：

致命错误：未捕获的意外值异常：服务器返回意外值。预期的"HTTP/1.1 101"，有"

请帮忙吗？

我遇到了同样的问题。

我通过更改ElephantIO的版本来修复它。

在我更改emit_test.php：

use ElephantIOEngineSocketIOVersion1X;
$version = new Version1X("http://localhost:3001");

到此版本

use ElephantIOEngineSocketIOVersion2X;
$version = new Version2X("http://localhost:3001");
