无法从php中的任何HTTP请求获取参数

Question

我无法从php // input获取请求参数，它总是返回空字符串。$ _POST也总是空的，我可以获取参数的唯一方法是使用$ _REQUEST，但我不确定这是否是解决此问题的正确方法。var_dump(file_get_contents("php://input"));返回：string（0）“”var_dump($_POST);返回：array（0）{}var_dump($_REQUEST);返回：array（2）{[“” ergerg“] => string（6）” ergerg“ [” regergerg“] => string（6）” ergreg“}我在邮递员中的要求如下：POST  /api/ajax.php?ergerg=ergerg&regergerg=ergregresponseStatus:200 OKTime:192 msSize:236 Bajax.php<?phpinclude "config.php";$rest_json = file_get_contents("php://input");$obj = json_decode($rest_json);$request = $obj->request;if($request == 1){    $userData = mysqli_query($con, "select * from rows");    $response = array();    while ($row = mysqli_fetch_assoc($userData)) {        $response[] = $row;    }    echo json_encode($response);}if($request == 2){    $platform   = $data->platform;    $container1 = $data->container1;    $container2 = $data->container2;    $ZPU1       = $data->ZPU1;    $ZPU2       = $data->ZPU2;    $reportId   = $data->reportId;    mysqli_query($con, "INSERT INTO                             rows(platform,container1,container2,                                ZPU1,ZPU2,reportId)                     VALUES('" . $platform . "','" . $container1 . "','" .                             $container2 . "','" . $ZPU1 . "','" . $ZPU2 .                             "','" . $reportId . "')");    echo "Insert successfully";}exit;在配置文件中，只有与mysql数据库的连接：config.php<?php$host = "localhost"; /* Host name */$user = "root"; /* User */$password = "password"; /* Password */$dbname = "dbname"; /* Database name */$con = mysqli_connect($host, $user, $password,$dbname);// Check connectionif (!$con) {  die("Connection failed: " . mysqli_connect_error());}
