POST空不管请求

Question

我使用jQuery提交以下请求:

$.ajax({
url: encodeURI('/server/api/user/update.php/'),
method: 'POST',
contentType: 'application/json',
headers: {
'Authorization': 'Bearer ' + utility.getJsonWebToken()
},
data: JSON.stringify(e.model),
dataType: 'json'
})

我有以下PHP代码来验证请求是有效的，并包含必要的正文:

// check for bad method
if ($_SERVER['REQUEST_METHOD'] !== 'POST') {
http_response_code(405);
$returnedJson['error'] = 'The supplied request method is not supported for the requested resource. This resource expects a POST request.';
echo json_encode($returnedJson);
return;
}
// check for bad request
$errors = array();
$user = new UserModel();
foreach (UserModel::$RequiredColumnNames as $property) {
$success = ControllerUtility::isValueInRequest($_POST, $property);
if (!$success) {
array_push($errors, $property);
continue;
}
$user->$property = $_POST[$property];
}
if (count($errors) > 0) {
http_response_code(400);
$returnedJson['error'] = 'Malformed request syntax. The following properties are missing from the request: ' . join(', ', $errors);
echo json_encode($returnedJson);
return;
}

每次我提交请求，我得到400错误与'格式不正确的请求语法。请求中缺少以下属性:…'错误信息。

我重复了$_POST和$_REQUEST，但在两个实例中都返回空数组。

我验证了请求头是POST:

POST /server/api/user/update.php/ HTTP/1.1
Host: localhost
User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:86.0) Gecko/20100101 Firefox/86.0
Accept: application/json, text/javascript, */*; q=0.01
Accept-Language: en-US,en;q=0.5
Accept-Encoding: gzip, deflate
Content-Type: application/json
Authorization: Bearer -removed-
X-Requested-With: XMLHttpRequest
Content-Length: 180
Origin: http://localhost
Connection: keep-alive
Referer: -removed-
Sec-GPC: 1

字段包含在我的请求JSON中:

{
"CreatedBy": null,
"CreatedOn": "2021-02-28 13:53:54",
"DeletedOn": null,
"Email": "-removed-",
"ModifiedBy": "1",
"ModifiedOn": "2021-02-28 16:35:51",
"UserId": "1",
"Username": "Adminn"
}

我甚至从PHP中删除了内容类型头，但没有成功。我还尝试过通过e.model而不是在AJAX请求中调用stringify。在这一点上，我不知道我做错了什么。

//从php返回json字符串://input.

file_get_contents('php://input');
