我正在创建一个使用开放琐事DB和PHP的问答网络应用程序。我现在的问题是检查用户选择的选项是否正确。我意识到这个程序正在进行另一个API调用，每次都会得到一组完全不同的问题，所以使用所选选项检查的选项完全不同。我是否可以存储API的第一个结果，然后用它检查所选的结果，而不是每次都进行新的调用？

这是我的控制器

代码语言：javascript
复制
public function callAPI($method, $url, $data){
    $curl = curl_init();
    switch ($method){
      case "POST":
         curl_setopt($curl, CURLOPT_POST, 1);
         if ($data)
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
         break;
      case "PUT":
         curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");
         if ($data)
            curl_setopt($curl, CURLOPT_POSTFIELDS, $data);                              
         break;
      default:
         if ($data)
            $url = sprintf("%s?%s", $url, http_build_query($data));
   }
   curl_setopt($curl, CURLOPT_URL, $url);
   curl_setopt($curl, CURLOPT_HTTPHEADER, array(
      'APIKEY:xxxxxx',
      'Content-Type: application/json',
   ));
   curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
   curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
   $result = curl_exec($curl);
   if(!$result){die("Connection Failure");}
   curl_close($curl);
   return $result;
}

    public function quiz()
    {
        $get_data= $this->callAPI('GET', 'https://opentdb.com/api.php?amount=10&category=18', false);
$data = json_decode($get_data, true);
        if($_SERVER["REQUEST_METHOD"]=="POST")
            {
              $sum = 0;  
                 foreach ($data as $key => $value)
                 {
                    foreach ($value as $key => $k)
                    {
                        if($_POST[$key]== $k['correct_answer'])
                        {
                            $sum++;
                        }
                        
echo"The question is ".$k['question']."you answered  $_POST[$key] and the correct answer is  ". $k['correct_answer']. " Your score is $sum"; // I used this line to find out that the problem.
                    }
                    
                 }
  
                    }
        else
        {
        $this->view('quiz', $data);
        }
    }

这是我的观点

代码语言：javascript
复制
<div class="col-md-6 grid-margin stretch-card ">
    <form class="my-auto" id ="regForm" method="POST" action="">
        <div class="card">
            <div class="card-body">
                 <?
                 foreach ($data as $key => $value):
                    foreach ($value as $key => $k):?>
                         <div class="tab">
                             <span><p><? echo $key+1  ?></p></span>
                             <h4 class="card-title"> <? echo $k["question"] .  "<br>";?></h4>
                                 <? foreach ( $k["incorrect_answers"] as $incorrect):
                               ?>
        <div class="form-check">
            <label class="form-check-label" for="radio1"></label>
    <input type="radio" class="form-check-input" id="radio1" name="<? echo $key ?>" value="<? echo " $incorrect"; ?>"> <? echo " $incorrect"; ?>
    
</div>
                    <?endforeach ?>
                   <input type="radio" class="form-check-input" id="rad2" name="<? echo "$key" ?>" value="<? echo $k["correct_answer"]; ?>"> <? echo  $k["correct_answer"]; ?> 
                   
                <div style="overflow:auto;">
                    <div style="float:right;">

好的，您正在执行一个API请求，呈现一个带有问题的页面，然后当用户提交答案时，要重用来自原始API的结果，确认答案是正确的吗？

由于api不允许您使用请求哈希或问题ID检索相同的问题，因此需要在代码中引入一个层，该层存储来自API请求的信息，以便在下一个请求中使用。

查看您的编码级别，最简单的解决方案是开始使用$_SESSION全局存储将问题数组存储到会话中，然后当用户提交他们的答案时检查这个会话信息。

虽然我认为您应该有足够的时间来查看文档并进一步发展，但是让我们把这一点讲一下：

代码语言：javascript
复制
        public function callAPI($method, $url, $data){
    $curl = curl_init();
    switch ($method){
        case "POST":
            curl_setopt($curl, CURLOPT_POST, 1);
            if ($data)
                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            break;
        case "PUT":
            curl_setopt($curl, CURLOPT_CUSTOMREQUEST, "PUT");
            if ($data)
                curl_setopt($curl, CURLOPT_POSTFIELDS, $data);
            break;
        default:
            if ($data)
                $url = sprintf("%s?%s", $url, http_build_query($data));
    }
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_HTTPHEADER, array(
        'APIKEY:xxxxxx',
        'Content-Type: application/json',
    ));
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    $result = curl_exec($curl);
    if(!$result){die("Connection Failure");}
    curl_close($curl);
    $_SESSION['quizQuestions'] = $result;
    return $result;
}

public function quiz()
{
    if($_SERVER["REQUEST_METHOD"]=="POST" && isset($_SESSION['quizQuestions']))
    {
        $sum = 0;
        foreach ($_SESSION['quizQuestions'] as $key => $value)
        {
            foreach ($value as $key => $k)
            {
                if($_POST[$key]== $k['correct_answer'])
                {
                    $sum++;
                }

                echo"The question is ".$k['question']."you answered  $_POST[$key] and the correct answer is  ". $k['correct_answer']. " Your score is $sum"; // I used this line to find out that the problem.
            }

        }
        $_SESSION['quizQuestions'] = null;
        // render view..
    }
    else
    {
        $get_data= $this->callAPI('GET', 'https://opentdb.com/api.php?amount=10&category=18', false);
        $data = json_decode($get_data, true);
        $this->view('quiz', $data);
    }
}

这显然需要更多的工作，但我希望你明白要点。还请注意，$_POST[key]键中的修复将被视为常量，而不是变量。

你的问题不够清晰。我想它应该说

我做了一个API请求来获取问题和答案。我创建了一个带有<form>的HTML页面来问问题。然后，表单向脚本发出post请求，在那里我检查答案。当玩家提交答案时，我需要存储要使用的答案。

根据链接中的API文档，您只能执行GET请求。

因此，post字段不适用。

代码语言：javascript
复制
$request = array();
$request[] = "Accept: application/json";
$ch = curl_init();
curl_setopt($ch, CURLOPT_HTTPHEADER, $request);
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 10);    
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);   
curl_setopt($ch, CURLOPT_URL, 'https://opentdb.com/api.php?amount=10&category=21&difficulty=easy&type=multiple'); 
curl_setopt($ch, CURLOPT_HEADER, false);
curl_setopt($ch, CURLOPT_TIMEOUT,10);
curl_setopt($ch, CURLOPT_FAILONERROR,true);
curl_setopt($ch, CURLOPT_POST, false);
curl_setopt($ch, CURLOPT_HTTPGET, true);
curl_setopt($ch, CURLOPT_ENCODING,"");
curl_setopt($ch, CURLOPT_VERBOSE, true);

$response = json_decode(curl_exec($ch),true);
var_export($response);

上面的内容返回如下：

复制

  'response_code' => 0,

      'correct_answer' => '1-7',

      array (
        0 => '1-5',
        1 => '1-6',
        2 => '2-6',
      ),
    ),
  ),
)

我不明白这点：

$_SERVER["REQUEST_METHOD"]是多余的。

还不清楚这是球员发帖的答案。

如果没有post，脚本就不会运行。

如果您使用的是$_SERVER["REQUEST_METHOD"]，就好像您的curl请求将设置$_SERVER["REQUEST_METHOD"]的值一样，它不会。

这是错误的。

代码语言：javascript
复制
curl_setopt($curl, CURLOPT_HTTPHEADER, array(
      'APIKEY:xxxxxx',
      'Content-Type: application/json',
   ));

除非链接中有更多的文档，否则Content-Type: application/json是不正确的。

API文档说的是

使用此API不需要API密钥，只需生成下面的URL，在您自己的应用程序中使用它来检索琐事问题。

而且我没有发现任何文档表明请求应该是JSON。

我唯一能找到的请求格式是：

代码语言：javascript
复制
https://opentdb.com/api.php?amount=10&category=21&difficulty=medium&type=multiple

这不是POST请求、JSON请求或PUT请求。

这是GET请求。

解压缩结果嵌套数组的方式是有问题的。

这是错误的。

代码语言：javascript
复制
 foreach ($data as $key => $value){
   foreach ($value as $key => $k){

它可能应该像这样($key只使用一次)

代码语言：javascript
复制
 foreach ($data as $value){
   foreach ($value as $key => $k){

不过，第一个预见应该是这样的：

代码语言：javascript
复制
foreach($data['results'] as $key => list(,,,$question,$correctAnswer,$incorrectAnswers){
  $data[$key]['question'] = $question; 
  $data[$key]['correctAnswer'] = $correctAnswer; 
  $data[$key]['incorrectAnserers'] = $incorrectAnswers;

}您应该有一个玩家id，用他们的id保存问题和答案。

我经常使用他们的ip地址作为用户id。

代码语言：javascript
复制
$id= intval(str_replace('.','',$_SERVER['REMOTE_ADDR']));

$jsn = json_encode($data,true);
file_put_contents("$id.jsn",$jsn);

然后为这些问题制作HTML表单。

您确实应该为玩家输入答案的表单提供HTML。因此，我将使用一个非常简化的形式。然后，将$form放到问题HTML中。

代码语言：javascript
复制
$form = '';
$form ."<form action="#" method="post>";
foreach($data as $number =>  list($question,$correctAnswer,$choices){
   $choices[] = $correctAnswer;
   shuffle($choices);
   $form .= "Q$number: $question<br>\n";
   $form .= "<input type=\"radio\" name=\"a$number\"  /> $choice[0]<br>\n";
   $form .= "<input type=\"radio\" name=\"a$number\"  /> $choice[1]<br>\n";       
   $form .= "<input type=\"radio\" name=\"a$number\"  /> $choice[2]<br>\n";       
   $form .= "<input type=\"radio\" name=\"a$number\"  /> $choice[3]<br>\n";
}
$form .= "<input type=\"hidden\" name=\"id\" value="$id\"\n";
$form .= "</form><br>\n";

然后，当答案被提交时，再次得到问题和答案。

代码语言：javascript
复制
$id = intval($_POST['id']);
$data = json_decode(file_get_contents("$is.jsn"),true);
