從頭開(kāi)始為您的Web應(yīng)用程序構(gòu)建用戶身份驗(yàn)證系統(tǒng)可能是一項(xiàng)非常棘手的工作。一開(kāi)始看起來(lái)很簡(jiǎn)單,但是有很多細(xì)節(jié)你必須考慮-正確散列密碼,保護(hù)用戶會(huì)話,提供一種重置忘記密碼的方法。大多數(shù)現(xiàn)代框架都提供了處理所有這些問(wèn)題的樣板代碼,但即使您沒(méi)有使用框架,也不要絕望。在本文中,我將向您展示如何從頭開(kāi)始構(gòu)建一個(gè)PHP應(yīng)用程序(只需依賴一個(gè)外部庫(kù)DotEnv,這樣我們就可以將機(jī)密存儲(chǔ)在代碼庫(kù)外部的.env文件中)。該應(yīng)用程序?qū)⒗肙kta簡(jiǎn)單的OAuth2.0API提供用戶登錄/注銷、新用戶注冊(cè)和“忘記密碼”表單。
所有你需要遵循的教程是一個(gè)Okta開(kāi)發(fā)人員帳戶(你可以免費(fèi)創(chuàng)建一個(gè)),PHP和Composer。
為什么使用Okta進(jìn)行身份驗(yàn)證?
Okta使身份管理比以前更簡(jiǎn)單、更安全、更可擴(kuò)展。Okta是一個(gè)API服務(wù),允許您創(chuàng)建、編輯和安全地存儲(chǔ)用戶帳戶和用戶帳戶數(shù)據(jù),并將它們與一個(gè)或多個(gè)應(yīng)用程序連接。我們的API使您能夠:
對(duì)您的用戶進(jìn)行身份驗(yàn)證和授權(quán)
存儲(chǔ)有關(guān)用戶的數(shù)據(jù)
執(zhí)行基于密碼的社交登錄
使用多因素身份驗(yàn)證保護(hù)您的應(yīng)用程序
等等!有關(guān)更多信息,請(qǐng)查看我們的產(chǎn)品文檔
注冊(cè)一個(gè)永久免費(fèi)的開(kāi)發(fā)人員帳戶,完成后,回來(lái)學(xué)習(xí)如何從頭開(kāi)始使用用戶身份驗(yàn)證構(gòu)建PHP應(yīng)用程序。
創(chuàng)建一個(gè)免費(fèi)的Okta開(kāi)發(fā)者帳戶
在繼續(xù)之前,您需要登錄到您的Okta帳戶(或者免費(fèi)創(chuàng)建一個(gè)新帳戶)并創(chuàng)建一個(gè)OAuth應(yīng)用程序。您需要為應(yīng)用程序獲取客戶機(jī)ID和客戶機(jī)機(jī)密,還需要一個(gè)API令牌,以便應(yīng)用程序可以遠(yuǎn)程注冊(cè)用戶。
以下是逐步說(shuō)明:
轉(zhuǎn)到“應(yīng)用程序”菜單項(xiàng)并單擊“添加應(yīng)用程序”按鈕:
選擇Web并單擊Next。
輸入標(biāo)題,然后設(shè)置http://localhost:8080/作為基本URI和登錄重定向URI,然后單擊“完成”。您可以保留其余的設(shè)置:
從應(yīng)用程序設(shè)置復(fù)制客戶端ID和客戶端機(jī)密。
轉(zhuǎn)到API>;令牌,然后單擊創(chuàng)建令牌:
為您的令牌輸入一個(gè)標(biāo)題,并確保復(fù)制令牌的值并安全地存儲(chǔ)它。你只能看到它一次-如果你丟失了它,你需要?jiǎng)?chuàng)建一個(gè)新的令牌。
注意你的主要組織URL,你也需要這個(gè)。
創(chuàng)建項(xiàng)目骨架
首先在頂層目錄中創(chuàng)建一個(gè)/src目錄和一個(gè)簡(jiǎn)單的composer.json
文件,其中只有一個(gè)依賴項(xiàng):DotEnv庫(kù),它允許我們將Okta身份驗(yàn)證詳細(xì)信息保存在代碼庫(kù)外部的.env
文件中:
composer.json
{
"require": {
"vlucas/phpdotenv": "^2.4"
},
"autoload": {
"psr-4": {
"Src\": "src/"
}
}
}
我們還配置了一個(gè)PSR-4自動(dòng)加載程序,它將自動(dòng)在/src
目錄中查找PHP類。
我們現(xiàn)在可以安裝依賴項(xiàng):
composer install
我們有一個(gè)/vendor
目錄,并且安裝了DotEnv依賴項(xiàng)(我們也可以使用autoloader從/src
加載類,而不需要調(diào)用include()
)。
讓我們?yōu)槲覀兊捻?xiàng)目創(chuàng)建一個(gè).gitignore
文件,其中有兩行,因此/vendor
目錄和本地.env
文件將被忽略:
/vendor
.env
接下來(lái),我們將為Okta身份驗(yàn)證變量創(chuàng)建一個(gè).env.example
文件:
CLIENT_ID=
CLIENT_SECRET=
REDIRECT_URI=http://localhost:8080/
METADATA_URL=https://{yourOktaDomain}/oauth2/default/.well-known/oauth-authorization-server
API_URL_BASE=https://{yourOktaDomain}/api/v1/
API_TOKEN=
以及一個(gè).env
文件,我們將在其中填寫來(lái)自O(shè)kta帳戶的實(shí)際詳細(xì)信息(Git將忽略它,這樣它就不會(huì)出現(xiàn)在我們的存儲(chǔ)庫(kù)中)。
項(xiàng)目將具有以下目錄結(jié)構(gòu)(您現(xiàn)在可以創(chuàng)建其余文件):
/public/index.php
/src
/controllers
/services
/views
bootstrap.php
.env
.env.example
/public/index.php
文件是我們的簡(jiǎn)單前端控制器。它加載bootstrap.php
腳本,然后處理傳入的HTTP請(qǐng)求,將其委托給控制器。以下是初始版本:
/public/index.php
<?php
require('../bootstrap.php');
// view data
$data = null;
view('home', $data);
現(xiàn)在,它只是加載沒(méi)有數(shù)據(jù)的“home”視圖。
bootstrap.php
腳本啟動(dòng)自動(dòng)加載,初始化我們的依賴項(xiàng)(在本例中只有DotEnv),啟動(dòng)會(huì)話并提供用于加載視圖文件的助手函數(shù)view()
(我們已經(jīng)在/public/index.php
中使用了它)。以下是bootstrap.php
文件的完整版本:
bootstrap.php
<?php
require 'vendor/autoload.php';
use DotenvDotenv;
$dotenv = new DotEnv( __DIR__ );
$dotenv->load();
session_start();
function view($title, $data = null)
{
$filename = __DIR__. '/src/views/' . $title . '.php';
if (file_exists($filename)) {
include($filename);
} else {
throw new Exception('View ' . $title . ' not found!');
}
}
/src/controllers
目錄保存我們的控制器類。/src/services
目錄保存服務(wù)層的類。/src/views
目錄保存我們的視圖(我們?cè)谶@個(gè)項(xiàng)目中使用簡(jiǎn)單的PHP視圖,沒(méi)有模板系統(tǒng))。
讓我們開(kāi)始構(gòu)建視圖:
/src/views/home.php
<?php view('header', $data); ?>
<section class="hero">
<div class="hero-body">
<div class="container">
<?php
if (isset($data['thank_you'])) {
?>
<div class="notification is-info">
<?php
echo $data['thank_you'];
?>
</div>
<?php
}
?>
<?php
if (isset($data['loginError'])) {
?>
<div class="notification is-danger">
<?php
echo $data['loginError'];
?>
</div>
<?php
}
?>
<?php
if (isset($_SESSION['username'])) {
?>
<p class="subtitle is-4">
This is some great content for logged in users
<p>
<?php
} else {
?>
<p class="subtitle is-4">
You need to login to access the content!
</p>
<?php
}
?>
</div>
</div>
</section>
<?php view('footer'); ?>
homepage視圖加載頁(yè)眉和頁(yè)腳,并且能夠顯示通知消息和錯(cuò)誤消息。它還根據(jù)用戶是否登錄(通過(guò)檢查$_SESSION['username']
確定)顯示不同的內(nèi)容。
以下是頁(yè)眉和頁(yè)腳視圖的完整版本:
/src/views/header.php

頭部加載bulmacss框架,如果有登錄用戶,則顯示用戶名和注銷鏈接;如果沒(méi)有登錄用戶,則顯示登錄/忘記密碼/注冊(cè)鏈接。
啟動(dòng)內(nèi)置PHP服務(wù)器:
php -S 127.0.0.1:8080 -t public
加載時(shí)http://localhost:8080,您應(yīng)該看到應(yīng)用程序:
實(shí)施Okta登錄/注銷
Okta登錄分為幾個(gè)階段:
建立登錄URL
重定向到URL
遠(yuǎn)程執(zhí)行Okta身份驗(yàn)證,然后重定向回我們的重定向URI
處理響應(yīng)并授權(quán)應(yīng)用程序中的用戶。
我們將public/index.php
修改為處理上面的步驟1和步驟2,并將其添加到view('home');
行的上方:
// build login URL and redirect the user
if (isset($_REQUEST['login']) && (! isset($_SESSION['username']))) {
$_SESSION['state'] = bin2hex(random_bytes(5));
$authorizeUrl = $oktaApi->buildAuthorizeUrl($_SESSION['state']);
header('Location: ' . $authorizeUrl);
die();
}
當(dāng)它收到重定向回(包括來(lái)自O(shè)kta的代碼)時(shí),還要處理步驟4:
if (isset($_GET['code'])) {
$result = $oktaApi->authorizeUser();
if (isset($result['error'])) {
$data['loginError'] = $result['errorMessage'];
}
}
我們還將添加一個(gè)非常簡(jiǎn)單的注銷處理程序,它只是取消設(shè)置會(huì)話變量username
。
新版本如下:
/public/index.php
<?php
require('../bootstrap.php');
use SrcServicesOktaApiService;
$oktaApi = new OktaApiService;
// view data
$data = null;
// build login URL and redirect the user
if (isset($_REQUEST['login']) && (! isset($_SESSION['username']))) {
$_SESSION['state'] = bin2hex(random_bytes(5));
$authorizeUrl = $oktaApi->buildAuthorizeUrl($_SESSION['state']);
header('Location: ' . $authorizeUrl);
die();
}
// handle the redirect back
if (isset($_GET['code'])) {
$result = $oktaApi->authorizeUser();
if (isset($result['error'])) {
$data['loginError'] = $result['errorMessage'];
}
}
if (isset($_REQUEST['logout'])) {
unset($_SESSION['username']);
header('Location: /');
die();
}
view('home', $data);
我們還要構(gòu)建OktaApiService
并添加所需的方法(buildAuthorizeUrl()
和authorizeUser()
):
/src/services/OktaApiService.php
<?php
namespace SrcServices;
class OktaApiService
{
private $clientId;
private $clientSecret;
private $redirectUri;
private $metadataUrl;
private $apiToken;
private $apiUrlBase;
public function __construct()
{
$this->clientId = getenv('CLIENT_ID');
$this->clientSecret = getenv('CLIENT_SECRET');
$this->redirectUri = getenv('REDIRECT_URI');
$this->metadataUrl = getenv('METADATA_URL');
$this->apiToken = getenv('API_TOKEN');
$this->apiUrlBase = getenv('API_URL_BASE');
}
public function buildAuthorizeUrl($state)
{
$metadata = $this->httpRequest($this->metadataUrl);
$url = $metadata->authorization_endpoint . '?' . http_build_query([
'response_type' => 'code',
'client_id' => $this->clientId,
'redirect_uri' => $this->redirectUri,
'state' => $state,
]);
return $url;
}
public function authorizeUser()
{
if ($_SESSION['state'] != $_GET['state']) {
$result['error'] = true;
$result['errorMessage'] = 'Authorization server returned an invalid state parameter';
return $result;
}
if (isset($_GET['error'])) {
$result['error'] = true;
$result['errorMessage'] = 'Authorization server returned an error: '.htmlspecialchars($_GET['error']);
return $result;
}
$metadata = $this->httpRequest($this->metadataUrl);
$response = $this->httpRequest($metadata->token_endpoint, [
'grant_type' => 'authorization_code',
'code' => $_GET['code'],
'redirect_uri' => $this->redirectUri,
'client_id' => $this->clientId,
'client_secret' => $this->clientSecret
]);
if (! isset($response->access_token)) {
$result['error'] = true;
$result['errorMessage'] = 'Error fetching access token!';
return $result;
}
$_SESSION['access_token'] = $response->access_token;
$token = $this->httpRequest($metadata->introspection_endpoint, [
'token' => $response->access_token,
'client_id' => $this->clientId,
'client_secret' => $this->clientSecret
]);
if ($token->active == 1) {
$_SESSION['username'] = $token->username;
$result['success'] = true;
return $result;
}
}
private function httpRequest($url, $params = null)
{
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
if ($params) {
curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($params));
}
return json_decode(curl_exec($ch));
}
}
在OktaApiService
類中發(fā)生了很多事情,讓我來(lái)解釋一下這個(gè)過(guò)程:
在構(gòu)建授權(quán)URL之前,我們生成一個(gè)隨機(jī)值,用于驗(yàn)證響應(yīng):
$_SESSION['state'] = bin2hex(random_bytes(5));
$authorizeUrl = $oktaApi->buildAuthorizeUrl($_SESSION['state']);
方法buildAuthorizeUrl()
使用對(duì)元數(shù)據(jù)URL的調(diào)用來(lái)獲取服務(wù)器的授權(quán)端點(diǎn),然后為該端點(diǎn)構(gòu)建查詢:
$metadata = $this->httpRequest($this->metadataUrl);
$url = $metadata->authorization_endpoint . '?' . http_build_query([
'response_type' => 'code',
'client_id' => $this->clientId,
'redirect_uri' => $this->redirectUri,
'state' => $state,
]);
當(dāng)我們得到重定向回,我們收到的狀態(tài)變量,我們發(fā)送的授權(quán)重定向和代碼從Okta。當(dāng)我們得到一個(gè)代碼時(shí),我們調(diào)用authorizeUser()
方法,首先驗(yàn)證狀態(tài)值是否匹配并且響應(yīng)中沒(méi)有錯(cuò)誤代碼:
if ($_SESSION['state'] != $_GET['state']) {
$result['error'] = true;
$result['errorMessage'] = 'Authorization server returned an invalid state parameter';
return $result;
}
if (isset($_GET['error'])) {
$result['error'] = true;
$result['errorMessage'] = 'Authorization server returned an error: '.htmlspecialchars($_GET['error']);
return $result;
}
然后使用token_endpoint
(來(lái)自元數(shù)據(jù)調(diào)用)將代碼交換為訪問(wèn)令牌:
$metadata = $this->httpRequest($this->metadataUrl);
$response = $this->httpRequest($metadata->token_endpoint, [
'grant_type' => 'authorization_code',
'code' => $_GET['code'],
'redirect_uri' => $this->redirectUri,
'client_id' => $this->clientId,
'client_secret' => $this->clientSecret
]);
if (! isset($response->access_token)) {
$result['error'] = true;
$result['errorMessage'] = 'Error fetching access token!';
return $result;
}
$_SESSION['access_token'] = $response->access_token;
之后,我們使用內(nèi)省端點(diǎn)來(lái)確認(rèn)令牌有效且處于活動(dòng)狀態(tài),并獲取新授權(quán)用戶的用戶名:
$token = $this->httpRequest($metadata->introspection_endpoint, [
'token' => $response->access_token,
'client_id' => $this->clientId,
'client_secret' => $this->clientSecret
]);
if ($token->active == 1) {
$_SESSION['username'] = $token->username;
$result['success'] = true;
return $result;
}
通過(guò)Okta API注冊(cè)新用戶
新用戶注冊(cè)將在UserController
類中處理。前面的控制器需要三個(gè)處理器:
public/index.php
...
use SrcControllersUserController;
...
$userController = new UserController($oktaApi);
...
if (isset($_REQUEST['register'])) {
view('register');
die();
}
if (isset($_REQUEST['command']) && ($_REQUEST['command'] == 'register')) {
$userController->handleRegistrationPost();
die();
}
if (isset($_REQUEST['thankyou'])) {
$data['thank_you'] = 'Thank you for your registration!';
}
...
單擊寄存器鏈接時(shí),第一個(gè)處理程序只加載register
視圖:
/src/views/register.php
<?php view('header', $data); ?>
<section class="hero">
<div class="hero-body">
<div class="container">
<form method="post" action="/">
<?php
if ($data && $data['errors']) {
?>
<div class="notification is-danger">
<?php
echo "Errors:";
echo $data['errorMessage'];
?>
</div>
<?php
}
?>
<div class="field">
<label class="label">First Name</label>
<div class="control">
<input class="input" name="first_name" type="text" value="<?php if ($data) { echo $data['input']['first_name']; } ?>">
</div>
</div>
<div class="field">
<label class="label">Last Name</label>
<div class="control">
<input class="input" name="last_name" type="text" value="<?php if ($data) { echo $data['input']['last_name']; } ?>">
</div>
</div>
<div class="field">
<label class="label">Email</label>
<div class="control">
<input class="input" name="email" type="email" value="<?php if ($data) { echo $data['input']['email']; } ?>">
</div>
</div>
<div class="field">
<label class="label">Password</label>
<div class="control">
<input class="input" name="password" type="password" value="">
</div>
</div>
<div class="field">
<label class="label">Repeat Password</label>
<div class="control">
<input class="input" name="repeat_password" type="password" value="">
</div>
</div>
<input type="hidden" name="command" value="register">
<div class="control">
<button class="button is-link">Register</button>
<a class="button is-link" href="/">Cancel</a>
</div>
</form>
</div>
</div>
</section>
<?php view('footer'); ?>
提交表單時(shí),第二個(gè)處理程序?qū)⑽薪o用戶控制器:
/src/controllers/UserController.php
<?php
namespace SrcControllers;
use SrcServicesOktaApiService;
class UserController
{
private $errors = null;
private $errorMessage = null;
public function __construct(OktaApiService $oktaApi)
{
$this->oktaApi = $oktaApi;
}
public function handleRegistrationPost()
{
if ($_SERVER['REQUEST_METHOD'] === 'POST') {
$input = [
'first_name' => $_POST['first_name'],
'last_name' => $_POST['last_name'],
'email' => $_POST['email'],
'password' => $_POST['password'],
'repeat_password' => $_POST['repeat_password'],
];
// local form validation
$this->validateRegistrationForm($input);
if ($this->errors) {
$viewData = [
'input' => $input,
'errors' => $this->errors,
'errorMessage' => $this->errorMessage
];
view('register', $viewData);
return true;
}
// if local validation passes, attempt to register the user
// via the Okta API
$result = $this->oktaApi->registerUser($input);
$result = json_decode($result, true);
if (isset($result['errorCode'])) {
$viewData = [
'input' => $input,
'errors' => true,
'errorMessage' => '<br>(Okta) ' . $result['errorCauses'][0]['errorSummary']
];
view('register', $viewData);
return true;
}
header('Location: /?thankyou');
return true;
}
header('HTTP/1.0 405 Method Not Allowed');
die();
}
private function validateRegistrationForm($input)
{
$errorMessage = '';
$errors = false;
// validate field lengths
if (strlen($input['first_name']) > 50) {
$errorMessage .= "<br>'First Name' is too long (50 characters max)!";
$errors = true;
}
if (strlen($input['last_name']) > 50) {
$errorMessage .= "<br>'Last Name' is too long (50 characters max)!";
$errors = true;
}
if (strlen($input['email']) > 100) {
$errorMessage .= "<br>'Email' is too long (100 characters max)!";
$errors = true;
}
if (strlen($input['password']) > 72) {
$errorMessage .= "<br>'Password' is too long (72 characters max)!";
$errors = true;
}
if (strlen($input['password']) < 8) {
$errorMessage .= "<br>'Password' is too short (8 characters min)!";
$errors = true;
}
// validate field contents
if (empty($input['first_name'])) {
$errorMessage .= "<br>'First Name' is required!";
$errors = true;
}
if (empty($input['last_name'])) {
$errorMessage .= "<br>'Last Name' is required!";
$errors = true;
}
if (empty($input['email'])) {
$errorMessage .= "<br>'Email' is required!";
$errors = true;
} else if (! filter_var($input['email'], FILTER_VALIDATE_EMAIL)) {
$errorMessage .= "<br>Invalid email!";
$errors = true;
}
if (empty($input['password'])) {
$errorMessage .= "<br>'Password' is required!";
$errors = true;
}
if (empty($input['repeat_password'])) {
$errorMessage .= "<br>'Repeat Password' is required!";
$errors = true;
}
if ($input['password'] !== $input['repeat_password']) {
$errorMessage .= "<br>Passwords do not match!";
$errors = true;
}
$this->errors = $errors;
$this->errorMessage = $errorMessage;
}
}
我們還需要將新方法registerUser()
添加到OktaApiService
類:
/src/services/OktaApiService.php
...
public function registerUser($input)
{
$data['profile'] = [
'firstName' => $input['first_name'],
'lastName' => $input['last_name'],
'email' => $input['email'],
'login' => $input['email']
];
$data['credentials'] = [
'password' => [
'value' => $input['password']
]
];
$data = json_encode($data);
$ch = curl_init($this->apiUrlBase . 'users');
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
'Accept: application/json',
'Content-Type: application/json',
'Content-Length: ' . strlen($data),
'Authorization: SSWS ' . $this->apiToken
]);
return curl_exec($ch);
}
...
注冊(cè)成功后,第三個(gè)處理程序只在儀表板上顯示一條消息“感謝您的注冊(cè)”。
表單如下所示,代碼包括驗(yàn)證和錯(cuò)誤處理(屏幕截圖顯示提交空表單后的輸出):
如果轉(zhuǎn)到用戶>人員,您可以在Okta管理面板中看到新用戶。
通過(guò)Okta API忘記密碼
“忘記密碼”功能將遵循相同的模式:
/public/index.php
中的新處理程序:
...
if (isset($_REQUEST['forgot'])) {
view('forgot');
die();
}
if (isset($_REQUEST['command']) && ($_REQUEST['command'] == 'forgot_password')) {
$userController->handleForgotPasswordPost();
die();
}
if (isset($_REQUEST['password_reset'])) {
$data['thank_you'] = 'You should receive an email with password reset instructions';
}
...
單擊忘記密碼鏈接時(shí),第一個(gè)處理程序加載forgot
視圖:
/src/views/forgot.php
<?php view('header', $data); ?>
<section class="hero">
<div class="hero-body">
<div class="container">
<form method="post" action="/">
<?php
if ($data && $data['errors']) {

提交表單時(shí),第二個(gè)處理程序?qū)⑽薪o用戶控制器:
/src/controllers/UserController.php
... public function handleForgotPasswordPost() { if ($_SERVER['REQUEST_METHOD'] === 'POST') { $input = [ 'email' => $_POST['email'] ]; // validate the email address if (empty($input['email']) || strlen($input['email']) > 100 || (! filter_var($input['email'], FILTER_VALIDATE_EMAIL))) { $viewData = [ 'input' => $input, 'errors' => true, 'errorMessage' => '
Invalid email!' ]; view('forgot', $viewData); return true; } // search for this user via the OktaApi $result = $this->oktaApi->findUser($input); $result = json_decode($result, true); if (! isset($result[0]['id'])) { $viewData = [ 'input' => $input, 'errors' => true, 'errorMessage' => '
User not found!' ]; view('forgot', $viewData); return true; } // attempt to send a reset link to this user $userId = $result[0]['id']; $result = $this->oktaApi->resetPassword($userId); header('Location: /?password_reset'); return true; } header('HTTP/1.0 405 Method Not Allowed'); die(); } ...
控制器使用來(lái)自OktaApiService
的兩種新方法:findUser()
和resetPassword()
:
/src/services/OktaApiService.php
...
public function findUser($input)
{
$url = $this->apiUrlBase . 'users?q=' . urlencode($input['email']) . '&limit=1';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
'Accept: application/json',
'Content-Type: application/json',
'Authorization: SSWS ' . $this->apiToken
]);
return curl_exec($ch);
}
public function resetPassword($userId)
{
$url = $this->apiUrlBase . 'users/' . $userId . '/lifecycle/reset_password';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, []);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, [
'Accept: application/json',
'Content-Type: application/json',
'Authorization: SSWS ' . $this->apiToken
]);
return curl_exec($ch);
}
...
第三個(gè)處理程序在觸發(fā)重置過(guò)程后在儀表板上顯示一條消息。
申請(qǐng)已經(jīng)完成了。您可以在Okta授權(quán)服務(wù)器中注冊(cè)新用戶,在Web應(yīng)用程序中對(duì)其進(jìn)行授權(quán),并遠(yuǎn)程觸發(fā)“重置密碼”例程。
像往常一樣,如果你有任何問(wèn)題,評(píng)論,或?qū)@篇文章的關(guān)注,請(qǐng)隨時(shí)在下面留下評(píng)論。
