我编写的 TcpLink 类有问题。该类连接到数据库，并且可以从 echo 语句接收简单的消息。但是，由于某种原因，TcpLink 类不会发送参数。有人可以帮帮我吗？

通过浏览器运行它会返回正确的结果： "array(1) { ["turtles"]=> string(3) "yes" }

但是，所有 UnrealScript 返回的是“array(0) { }”

PHP代码：

<?php
$response = "";
$response = var_dump($_GET);
echo $response;
?>

虚幻脚本代码：

    class PlayerStatsLinkClient extends TcpLink;

var string TargetHost;
var int TargetPort;
var String TargetPath;
var String RequestText; //Data To Send
var array<String> RequestQueue; //Data Waiting to be sent(used when request is already in progress)
var bool bRequestInProgress; //Currently Sending A Request

var PlayerController PC;

var bool bGetData;

var String RequestType;

//var TestDatabaseServices ServiceProvider; //Owner Service
var int SecurityKey; //Arbitrary number equivalent to what is in .php to check authority(Prevent hacking slightly[Easily hackable])

struct sParam
{
    var String Key;
    var String Value;
};

var array<sParam> ParamList;

delegate OnResponse(String Type, String Data);

function AddParam(string Key, string Value)
{
    local sParam param;

    param.Key = Key;
    param.Value = Value;

    ParamList.AddItem(param);
}

function SetStats(int level, int xp, int xpToNext){
    AddParam("level", string(level));
    AddParam("xp", string(xp));
    AddParam("xpToNext", string(xpToNext));    
}

function GetStatsFromServer(){
    bGetData = true;
    AddParam("COMMAND", "RETRIEVE");
    Execute();
    bRequestInProgress = true;
    `log("========== END GETSTATSFROMSERVER()");
}

function bool Execute()
{
    if(!SetRequest())
    {
        return false;
    }

    Resolve(targethost);

    bRequestInProgress = true;
    return true;
}

{
    local sParam param;
    local String tmpRequestText;

    tmpRequestText="securitykey="$SecurityKey;

    foreach ParamList(param)
    {
        tmpRequestText $= "&" $ param.Key $ "=" $ param.Value;
    }

    ParamList.Remove(0, ParamList.Length);

    if(!bRequestInProgress)
    {
        RequestText = tmpRequestText;
        return true;
    }
    else

这是因为您的Opened方法总是在建立连接后发送查询字符串（即 POST 请求）。应该传入您的 GET 参数TargetPath以使其正常工作。
