咕噜咕噜 400 个错误请求

当我执行 POST 请求时出现以下错误：

客户端错误：POST http://api.hitbox.tv/auth/login导致400 Bad Request响应：{"成功"：true，"错误"：false，"error_msg"："auth_failed"}

我不确定，那是因为我的 guzzle 代码有任何问题

require 'vendor/autoload.php';
use GuzzleHttp'Client;
use GuzzleHttp'Exception'ClientException;
$client = new Client(["base_uri"=>"http://api.hitbox.tv/"]);
$data = ["login"=>"myId","pass"=>"mypassword","rememberme"=>"",];
try{
$response = $client->request("POST","auth/login",["form-params"=>$data,"content-type"=>"application/x-www-form-urlencoded"]);   
}
catch(ClientException $e){
  echo  $e->getMessage();
}
catch(InvalidArgumentException $e){
    echo $e->getMessage();
}
var_dump(json_decode($response,true));

我已经尝试了相同的API与Javascript XMLHttpRequest来发布相同的数据集，在那里我得到了成功的结果。

var xmlhttp;

var data = '{"login":"myId","pass":"myPassword","rememberme":""}';
if(window.XMLHttpRequest){
    xmlhttp = new XMLHttpRequest();      
}
else{              
    xmlhttp = new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function(){
if(xmlhttp.readyState==4 && xmlhttp.status == 200){
    return xmlhttp.responseText;
}
xmlhttp.open('POST','https://api.hitbox.tv/auth/login',false);
xmlhttp.send(data);
