我想与Moodle 2.9的安装进行通信。
以下示例客户端稍作修改:https://github.com/moodlehq/sample-ws-clients/blob/master/PHP-REST/client.php使用Unirest而不是Curl和JSON而不是XML:
$token = 'd1c74d6466daaaaad59b5d99906bfc84';
$domainname = 'http://moodle.example.com';
$functionname = 'core_user_create_users';
// REST RETURNED VALUES FORMAT
$restformat = 'json';
$user1 = new \stdClass();
$user1->username = 'testusername1';
$user1->password = 'testpassword1';
$user1->firstname = 'testfirstname1';
$user1->lastname = 'testlastname1';
$user1->email = '[email protected]';
$user1->auth = 'manual';
$user1->idnumber = 'testidnumber1';
$user1->lang = 'en';
$user1->theme = 'standard';
$user1->timezone = '-12.5';
$user1->mailformat = 0;
$user1->description = 'Hello World!';
$user1->city = 'testcity1';
$user1->country = 'au';
$preferencename1 = 'preference1';
$preferencename2 = 'preference2';
$user1->preferences = array(
array('type' => $preferencename1, 'value' => 'preferencevalue1'),
array('type' => $preferencename2, 'value' => 'preferencevalue2'));
$user2 = new \stdClass();
$user2->username = 'testusername2';
$user2->password = 'testpassword2';
$user2->firstname = 'testfirstname2';
$user2->lastname = 'testlastname2';
$user2->email = '[email protected]';
$user2->timezone = 'Pacific/Port_Moresby';
$users = array($user1, $user2);
$params = array('users' => $users);
/// REST CALL
$serverurl = $domainname . '/webservice/rest/server.php' . '?wstoken=' . $token . '&wsfunction=' . $functionname;
//if rest format == 'xml', then we do not add the param for backward compatibility with Moodle < 2.2
$restformat = ($restformat == 'json') ? '&moodlewsrestformat=' . $restformat : '';
$headers = array('Accept' => 'application/json');
$response = UnirestRequest::post($serverurl . $restformat, $headers, json_encode($params));
执行时我收到一个错误:
“注意:数组转换为字符串”
据称是因为参与体内的参数。所以,我想我必须在发送之前序列化身体,但是当我尝试时:
$response = UnirestRequest::post($serverurl . $restformat, $headers, json_encode($params));
我从Moodle回来了:
{“exception”:“invalid_parameter_exception”,“errorcode”:“invalidparameter”,“message”:“Detectado valor de par \ u00e1metro no v \ u00e1lido”,“debuginfo”:“单个结构中缺少必需的密钥:用户”}◀ “
必须有一些我不了解POST请求必须如何的样子。有什么建议吗?
Moodle希望帖子的主体是URL编码的,所以你的身体必须使用http_build_query($params)
(或任何其他方法来编码你的数据)来构建,例如:
$convertedpostdata = implode('&', $params);//where $params is an array
至于为什么,我真的不记得,我记得前一段时间挣扎着实现,你可以查看[your_moodle_installation.com]/admin/webservice/documentation.php
获取更多文档,另外你这里是我所做的一个例子:
