Question

我试图发布以下json数据

{"name":"somename","email":"somemail","password":"abcdef"}

在我的api身上，

<?php


require_once 'include/DB_Functions.php';
$db = new DB_Functions();

// json response array
$response = array("error" => FALSE);

if (isset($_POST['name']) && isset($_POST['email']) && 
isset($_POST['password'])) {

// receiving the post params
$name = $_POST['name'];
$email = $_POST['email'];
$password = $_POST['password'];

// check if user is already existed with the same email
if ($db->isUserExisted($email)) {
    // user already existed
    $response["error"] = TRUE;
    $response["error_msg"] = "User already existed with " . $email;
    echo json_encode($response);
} else {
    // create a new user
    $user = $db->storeUser($name, $email, $password);
    if ($user) {
        // user stored successfully
        $response["error"] = FALSE;
        $response["uid"] = $user["unique_id"];
        $response["user"]["name"] = $user["name"];
        $response["user"]["email"] = $user["email"];
        $response["user"]["created_at"] = $user["created_at"];
        $response["user"]["updated_at"] = $user["updated_at"];
        echo json_encode($response);
    } else {
        // user failed to store
        $response["error"] = TRUE;
        $response["error_msg"] = "Unknown error occurred in registration!";
        echo json_encode($response);
    }
}
} else {
$response["error"] = TRUE;
$response["error_msg"] = "Required parameters (name, email or password) is 
missing!";
echo json_encode($response);
}
?>

我的问题是if (isset($_POST['name']) && isset($_POST['email']) && isset($_POST['password']))始终为false且消息为Required parameters (name, email or password) is missing! is shown

在wampserver日志中，错误以

的形式给出

PHP已弃用：自动填充$ HTTP_RAW_POST_DATA 已弃用，将在以后的版本中删除。为了避免这种情况警告在php.ini中将'always_populate_raw_post_data'设置为'-1'并使用改为php：//输入流。在第0行的未知中

Answer 1

如果将发布数据作为json发送，则在api中必须将输入数据解码为数组

$data = json_decode($_POST)

然后继续条件

if (isset($data['name'], $data['email'], $data['password']) {

Answer 2

注意：这是社区维基的答案。

根据$HTTP_RAW_POST_DATA

上的手册

http://php.net/manual/en/reserved.variables.httprawpostdata.php

“通常，应使用php：//输入而不是$ HTTP_RAW_POST_DATA。”。

OP在评论中也指出：

@ Fred-ii-谢谢，它通过添加像这样的$ postdata = file_get_contents（“php：// input”）;

无法在PHP中发布数据
