我正在用php构建一个简单的restful api。我可以读取使用GET发送的数据，但不能读取使用POST发送的数据。
$json_array=array(
"userId"=>'',
"refId"=>f(alea()),
"name"=>f($name),
"status"=>'0'
);
$insert = api("MyLists","POST","insertLists",$json_array);
发送请求的Api函数：
function api() {
global $apiKey;
global $apiURL;
// GET
$tab = func_get_args();
if($tab[1] == 'POST') {
// POST
$tab = func_get_args();
global $apiKey;
global $apiURL;
$url = $apiURL.$tab[0]."/".$apiKey."/".$tab[2];
$data = $tab[3];
$data_string = json_encode($data);
$rCURL = curl_init();
curl_setopt($rCURL, CURLOPT_URL, $url);
curl_setopt($rCURL, CURLOPT_POST, 1);
curl_setopt($rCURL, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($rCURL, CURLOPT_RETURNTRANSFER, true);
curl_setopt($rCURL, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($data_string))
);
$aData = curl_exec($rCURL);
curl_close($rCURL);
return json_decode($aData);
}
else {
$url = $apiURL.$tab[0]."/".$apiKey."/".$tab[1];
$i=2;
while(isset($tab[$i])) {
$url.="/".$tab[$i];
$i++;
}
// return $url;
$rCURL = curl_init();
curl_setopt($rCURL, CURLOPT_URL, $url);
curl_setopt($rCURL, CURLOPT_HEADER, 0);
curl_setopt($rCURL, CURLOPT_RETURNTRANSFER, 1);
$aData = curl_exec($rCURL);
curl_close($rCURL);
return json_decode($aData);
}
}
Php函数接收请求： AbstractApi.php
header("Access-Control-Allow-Orgin: *");
header("Access-Control-Allow-Methods: *");
header("Content-Type: application/json");
error_reporting(E_ERROR | E_WARNING | E_PARSE);
$method = $_SERVER['REQUEST_METHOD'];
if($method == "GET" || $method == "POST") {
$type=$_GET['type']."API";
if(file_exists("./".$type.".php")) {
require_once("./".$type.".php");
if (!array_key_exists('HTTP_ORIGIN', $_SERVER)) {
$_SERVER['HTTP_ORIGIN'] = $_SERVER['SERVER_NAME'];
}
try {
$API = new $type($_REQUEST['request'], $_SERVER['HTTP_ORIGIN']);
echo json_encode($API->processAPI());
} catch (Exception $e) {
echo json_encode(Array('error' => $e->getMessage()));
}
}
else {
echo json_encode(Array('error' => "Invalid Type"));
}
}
else {
echo json_encode(Array('error' => "Only accepts GET/POST requests"));
}

现在，对于GET请求，我在PHP类中使用$ this-＆gt; args来检索param并将其用于我的函数。但是当我使用POST时，我得到NULL作为回报，我在这个发布的脚本中检查了很多，但我没有找到检索Post字段的解决方案。 Thx提前:)）

你能尝试使用curl_setopt（$ rCURL，CURLOPT_CUSTOMREQUEST，＆＃34; POST＆＃34;）;而不是curl_setopt（$ rCURL，CURLOPT_POST，1）;在api函数中？，
OtherWise你可以使用file_get_contents设置一些选项，如：
$data_string = json_encode($data);
$result = file_get_contents($apiURL.$tab[0]."/".$apiKey."/".$tab[2], null, stream_context_create(array(
'http' => array(
'method' => 'POST',
'header' => 'Content-Type: application/json' . "\r\n"
. 'Content-Length: ' . strlen($data_string) . "\r\n",
'content' => $data_string,
),
)));
