PHP发布请求(CURL，JSON)不工作

Question

我带着这个问题谦虚地来到伟大的开发人员面前。以JSON格式向Firebase发送post请求。这是我的代码

$token = $_SESSION['token'];
$data = array(
'id' => 156,
'quizName' => $quizName,
'numberOfQuestions' => $numberOfQuestions, 
'isTimed' => true,                         
'numberOfMinutesToComplete' => $numberOfMinutesToComplete,
'targetedClass' => 'Js One',
'subject' => $subject_name,
'schoolLevel' => $schoolLevel,
'questions' => array('question' => $question, 'questionMark' => $marks, 
'options' => array('option' => 'A', 'answer'=> $optionA, 'option' => 'B', 'answer'=> $optionB, 'option' => 'C', 'answer' => $optionC, 'option' => 'D', 'answer' => $optionD, 'option' => 'E', 'answer' => $optionE),
'hasImage' => true,
'images' => array('images-1' => 'image-1', 'images-2' => 'image-2'),
'correctionOption' => $correct_option
),
'totalValidMarks' => $totalValidMarks,
'validUntil' => $validUntil
);
// API URL
$url = ' ';
// Create a new cURL resource
$ch = curl_init( $url );
# Setup request to send json via POST.
$payload = json_encode( array( "customer"=> $data ) );
curl_setopt( $ch, CURLOPT_POSTFIELDS, $payload );
curl_setopt( $ch, CURLOPT_HTTPHEADER, array('x-access-token:'.$token, 'Content-Type:application/json'));
# Return response instead of printing.
curl_setopt( $ch, CURLOPT_RETURNTRANSFER, true );
# Send request.
$result = curl_exec($ch);
curl_close($ch);
# Print response.
echo "<pre>$result.</pre>";

但我收到一个错误：

"details"：[｛"message"："\"id\"is required"，"path"：["id"]，"type"："any.required"，"context"：｛"label"："id"，"key"："id"｝]｝

请尝试这样发送：

$params = $myDataArray;
$data_string = json_encode($params);
$curl = curl_init();
curl_setopt_array($curl, array(
CURLOPT_URL => $toEndPoint,
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 30,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_POSTFIELDS => $data_string,
CURLOPT_HTTPHEADER => array(
"x-access-token: $token",
"cache-control: no-cache",
"content-type: application/json",
),
));
$response = curl_exec($curl);
$err = curl_error($curl);
curl_close($curl);
if ($err) {
echo "cURL Error #:" . $err;
} else {
echo $response;
}
exit;

@godlovesme，回答您的最新评论：

我真的不喜欢使用While循环，因为它们很容易让你陷入无休止的循环，但你会得到你想要的：

$i = 0;
$questionsArrFormatted = [];
while ($i < count($questionsArr)) {
$hasImage = count($questionsArr[$i]['question']) ? true : false;
$questionsArrFormatted[$i] = [
'question' => $questionsArr[$i]['question'],
'questionMark' => $questionsArr[$i]['marks'],
'options' => $questionsArr[$i]['options'], // options should be an array formatted like in your question
'hasImage' => $hasImage,
'images' => $questionsArr[$i]['images'],
'correctionOption' => $questionsArr[$i]['correct_answer']
];
$i++;
}
$data = array(
'id' => 156,
'quizName' => $quizName,
'numberOfQuestions' => $numberOfQuestions,
'isTimed' => true,
'numberOfMinutesToComplete' => $numberOfMinutesToComplete,
'targetedClass' => 'Js One',
'subject' => $subject_name,
'schoolLevel' => $schoolLevel,
'questions' => $questionsArrFormatted,
'totalValidMarks' => $totalValidMarks,
'validUntil' => $validUntil
);
