Question

我试图通过网络服务api在Moodle上创建一个新用户。

我尝试使用我在github上找到的example以及另一个php代码

在两者中我收到相同的回复：

“单个结构中缺少必需的密钥：用户”

回应：

{
    "exception":"invalid_parameter_exception",
    "errorcode":"invalidparameter",
    "message":"Invalid parameter value detected",
    "debuginfo":"Missing required key in single structure: users"
}

我尝试通过数组更改对象，但错误仍在继续。

我的代码：

$functionname = 'core_user_create_users';
$user1 = new stdClass();
$user1->id = 1;
$user1->username = 'testusername1';
$user1->password = 'testpassword1';
$user1->firstname = 'testfirstname1';
$user1->lastname = 'testlastname1';
$user1->email = 'testemail1@moodle.com';
$user1->auth = 'manual';
$user1->idnumber = 'testidnumber1';
$user1->description = 'Hello World!';
$user1->city = 'testcity1';
$user1->country = 'BR';



$token = 'mytoken';
$domainname = 'localhost/moodle';
$functionname = 'core_user_create_users';
$restformat = 'json';
$serverurl = $domainname . '/webservice/rest/server.php'. '?wstoken=' . $token . '&wsfunction='.$functionname.'&moodlewsrestformat=' . $restformat;

$users = array($user1);
$params = array('users' => $users); 

$context = stream_context_create(array(
    'http' => array(
        'method' => 'POST',                    
        'header' => 'Content-Type: text/plain',
        'content' => $params                             
    )
));

$contents = file_get_contents($serverurl, null, $context);            

//print_r($contents);

$resposta = json_decode($contents);

我有一个有效的令牌，允许用户使用core_user_create_users功能

Answer 1

与所需密钥'用户'相同的问题用这个=＆gt;

解决问题

$serverurl = $domainname . '/webservice/rest/server.php'. '?wstoken=' . $token . '&wsfunction='.$functionname;
    //require_once('../curl.php');
    $curl = new curl;
    $params = "&users[0][username]=loginnn&users[0][password]=4815162342Qq*&users[0][firstname]=allala&users[0][lastname]=trest&users[0][email]=ty@mail.ru";
    //if rest format == 'xml', then we do not add the param for backward compatibility with Moodle < 2.2
    $restformat = ($restformat == 'json')?'&moodlewsrestformat=' . $restformat:'';
    $resp = $curl->post($serverurl . $restformat, $params);

我认为您必须提高moodle系统的调试级别，我希望您能获得有关此错误的更多有用信息，调试将帮助您解决确切的问题。通过以下路径：

Home ► Site administration ► Development ► Debugging

从Developer level中选择debug messages并保存更改

我有一个类似的问题，根据我的经验，问题是@Component({ selector: 'panel-product-selection', template, providers: [ProductTreeService, UserApi], directives: [ProductTreeComponent] }) export class PanelProductSelectionComponent { private categoriesProductsTree: Collections.LinkedList<CategoryTreeElement>; private productTreeService: ProductTreeService; private userApi: UserApi; constructor(productTreeService: ProductTreeService, userApi: UserApi) { this.productTreeService = productTreeService; this.userApi = userApi; } ngOnInit(): void { //... } } Moodle需要一个大写字母的密码和至少一个像/的simbol。， - _等

尝试新密码也许有效......

Answer 4

不要将ID传递给用户数组，因为它不接受它作为参数。有关更多详细信息，请阅读WebService API文档以在Moodle中创建用户。

Answer 5

今天遇到了同样的需求，我用你的帖子从GitHUB获取代码所以我想我会告诉你我是如何修复错误的：

将您的代码更改为以下内容：

$users = array((array)$user1);
$params = array('users' => (array)$users);

GitHUB $ user1中的代码是一个对象。 Moodle需要一个数组。

以下是从Moodle的文档中复制的。

[users] =>
Array 
    (
    [0] =>
        Array 
            (
            [username] => string                
            [password] => string                
            [firstname] => string                
            [lastname] => string                
            [email] => string                
            [auth] => string                
            [idnumber] => string                
            [lang] => string                
            [calendartype] => string                
            [theme] => string                
            [timezone] => string

            [city] => string                
            [country] => string                
            [firstnamephonetic] => string

            [preferences] =>

                    (
                    [0] =>
                        Array 
                            (
                            [type] => string                                
                            [value] => string                                
                            )
                    )

                            [value] => string                                
                            )
                    )                
            )
    )

在我们的案例中，我们添加了Https支持，但我们仍在调用Moodle url的Http版本。改为Https解决了这个问题。

Answer 7

这已经过测试并且可以在Moodle 3.1.2上运行-我发现这是一个更干净，更容易理解的解决方案，它使用适当的数组（如Moodle期望的那样）本机cURL和http_build_query ...

确保您提供给Moodle的密码符合您的安全要求。

    $moodledata['users'][] = array(
        'username' => 'testuser123', 
        'password' => 'TestPass1!',
        'firstname' => 'Firstname',
        'lastname' => 'Lastname',
        'email' => 'test@test.com',
    );
    
    //open connection
    $token = 'your-token-goes-here';
    $domainname = 'https://yourmoodlesite.tld';
    $functionname = 'core_user_create_users';
    
    $url = $domainname . '/webservice/rest/server.php?wstoken=' . $token . '&wsfunction='.$functionname."&moodlewsrestformat=json";
    $ch = curl_init();

    //set the url, number of POST vars, POST data
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, http_build_query($moodledata));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

    //execute post, and get our JSON as defined above with moodlewsrestformat=json
    $result = curl_exec($ch);
        
    //if you want it in an array
    //$result = json_decode($result, true);

使用Moodle webservice创建用户
