我是Valence API和D2L(Brightspace)的新手,我目前在通过WordPress注册表单发送API请求时遇到问题。以下是我想要实现的一些步骤:
下面是用于发送创建的用户信息的格式的副本(RoldId正在D2L站点上使用,我正在使用方法'POST'和'/ d2l / api / lp /的API请求1.4 / users /'):
{
"OrgDefinedId": "SBoateng",
"FirstName": "Samuel",
"MiddleName": "",
"LastName": "Boateng",
"ExternalEmail": "daerdocta@gmail.com",
"UserName": "SBoateng",
"RoleId": 103,
"IsActive": true,
"SendCreationEmail": false
}
这是从请求中返回的内容:
Unexpected non-JSON response from the server:
Array
(
[headers] => Array
(
[cache-control] => private
[content-length] => 0
[server] => Microsoft-IIS/7.5
[x-powered-by] => ASP.NET
[x-xss-protection] => 0
[date] => Tue, 23 Jun 2015 18:35:05 GMT
[connection] => close
)
[body] =>
[response] => Array
(
[code] => 400
[message] => Bad request
)
[cookies] => Array
(
)
[filename] =>
)
答案 0 :(得分:1)
根据documentation for the create-user route,400
状态代码作为响应表示以下两种情况之一:您以某种方式为新用户记录提供了无效数据,或者后端服务是(由于某种原因)无法创建新的用户记录(非常罕见,但它确实发生)。在第二种情况下,您将在错误描述中获得更详细的消息,指示无法创建。由于你没有得到这个,最可能的原因是其中之一:
你没有发送你认为你发送的内容;它的格式很糟糕。
您提供的无效RoleId
- 它在您测试的环境中有效,但在生产环境中,RoleId
不存在。有时会发生这种情况,但在这种情况下,我怀疑没有。要进行验证,请先尝试按Id取回RoleId
,然后查看这些结果。
您提供的系统中已存在UserName
:此属性是您在登录Brightspace系统时用于标识自己的ID,因此它必须是唯一的。有时客户会发现他们正在使用的“临时测试”UserName
已经存在于他们的后端服务中,无论出于何种原因,这可能会导致意外失败。您可以先尝试通过UserName
取回用户来验证您是否已经拥有该用户的记录。

我已经能够在一些帮助下解决这个问题了。下面是我使用的代码,如果有其他人在将来遇到这个代码。
摘录保存表单的PHP:
<input class="required textInput" id="name_first" name="name_first" size="35" maxlength="255" placeholder= "First Name" type="text" value="<?php echo $_SESSION["student_profile"]["name_first"]; ?>" required />
<label class="required_lables" for="name_first"><em></em></label>
<!-- Middle Initial -->
<label for="name_middle"><em></em></label>
<input class="textInput optional" id="name_middle" name="name_middle" size="35" maxlength="255" placeholder= "Middle Name (optional)" type="text" value="<?php echo $_SESSION["student_profile"]["name_middle"]; ?>" />
<!-- Last Name -->
<input class="required textInput" id="name_last" name="name_last" size="35" maxlength="255" placeholder= "Last Name" type="text" value="<?php echo $_SESSION["student_profile"]["name_last"]; ?>" required/>
<label class="required_lables" for="name_last"><em></em></label>
表单提交页面。 Ajax调用在这里进行:
$ _ SESSION [&#39; student_profile&#39;] = $ _POST;
$如first_name = $ _ SESSION [&#39; student_profile&#39;] [&#39; name_first&#39;];
$ middle_name = $ _ SESSION [&#39; student_profile&#39;] [&#39; middle_name&#39;];
$ last_name = $ _ SESSION [&#39; student_profile&#39;] [&#39; last_name&#39;];
$ email = $ _ SESSION [&#39; student_profile&#39;] [&#39; email&#39;];
echo '<script>';
echo 'var data = {"OrgDefinedId": "'. $orgDefinedId .'", "FirstName": "'. $first_name .'", "MiddleName": "'. $middle_name .'", "LastName": "'. $last_name .'", "ExternalEmail": "'. $email .'", "UserName": "'. $uName .'", "RoleId": 103, "IsActive": true, "SendCreationEmail": false};';
echo 'var type = "CREATE";';
echo 'window.$vars = {dataField : data};';
echo 'window.$vartype = {typeField : type};';
echo 'doAPIRequest();';//direction to js file with the ajax call
echo '</script>';
?>
wordpress中使用的Ajax:使用的操作称为example_wordpress_action,它在functions.php中定义
function doAPIRequest() {
var host = "myHostSite.com";
var port = "443";
var scheme = "https";
var req = "/d2l/api/lp/1.4/users/";
var method = "POST";
var typeAPI = window.$vartype.typeField;
var ajaxurl = "/wp-admin/admin-ajax.php";
var data = window.$vars.dataField;
var userName = window.$varsUname.useNameField;
var anon = "";
var appId = myAppID;
var appKey = myAppKey;
$.ajax({
url: ajaxurl,
data: {
action : 'example_wordpress_action',
host: host,
port: port,
scheme: scheme,
anon: anon,
apiRequest: req,
typeapp: typeAPI,
apiMethod: method,
appUser: userName,
data: data,
appId: appId,
appKey: appKey
},
success: function(data) {
var output;
if(data == '') {
output = 'Success!';
return;
} else {
try {
output = JSON.stringify(JSON.parse(data), null, 4);
} catch(e) {
output = "Unexpected non-JSON response from the server: " + data;
}
}
},
error: function(jqXHR, textStatus, errorThrown) {
},
});
}
使用wp_remote_request进行请求的Funcions.php:
function example_wordpress_action_function(){
$host = $_GET['host'];
$port = $_GET['port'];
$scheme = $_GET['scheme'];
$data = $_GET['data'];
$apiMethod = $_GET['apiMethod'];
$appId = $_GET['appId'];
$appKey = $_GET['appKey'];
$appRequest = $_GET['apiRequest'];
$appUserName = $_GET['appUser'];
$data_string = json_encode($data);
$userId = $myUserId;
$userKey = $myUserKey;
$authContextFactory = new D2LAppContextFactory();
$authContext = $authContextFactory->createSecurityContext($appId, $appKey);
$hostSpec = new D2LHostSpec($host, $port, $scheme);
$opContext = $authContext->createUserContextFromHostSpec($hostSpec, $userId, $userKey);
$uri = $opContext->createAuthenticatedUri($appRequest, $apiMethod);
$headers = array( 'authorization' => 'basic ', 'accept' => 'application/json', 'content-type' => 'application/json', 'content-length' => strlen( $data_string ) );
$post = array( 'method' => $apiMethod, 'headers' => $headers, 'body' => $data_string );
$createResponses = wp_remote_request($uri, $post);
die();
}
add_action( 'wp_ajax_example_wordpress_action', 'example_wordpress_action_function' );
add_action("wp_ajax_nopriv_example_wordpress_action", "example_wordpress_action_function");
