调用未定义方法GuzzleHttpCommandResult::getBody()

Question

我试图从json格式的外部API在Drupal中获得响应。我正在使用HTTP客户端管理器Drupal模块。现在我只能在数组中获得stdClass对象格式的响应，所有响应键值都缺失。

我的原始代码:

public function findPosts() {
$client = $this->getClient();
$params = array('client_Id' => "12345",
"client_Secret" => "42452454",
"scope" => "read");
$response = $client->FindPosts($params);
dpm($response);
return ['#markup' => $response];
}

输出下面的代码。我需要它看起来像[access_token] =>[type] =>持票人等。

stdClass Object
(
[__CLASS__] => GuzzleHttpCommandResult
[data:protected] => Array
(
[0] => eyJhbGciOiJIUzUxMiIsIn
[1] => bearer
[2] => 3600
[3] => 2022-11-09T10:48:47+00:00
[4] => read
[5] => MwA1ADkAZAA0AGIAZAA4AC0AOQAzADcA
[6] => 86400
[7] => 2022-11-10T09:48:47+00:00
)
)

当我尝试$response->getBody()或$response->getContent()或任何其他响应方法时，它返回以下错误。

正如@bwaindwain提到的toArray()方法可以代替getBody()。

toArray()方法适用于格式为

的响应。

[
{
"token": "4354iojegdjss"
}
]

然而，使用这种响应格式，所有键仍然消失:

{
"token": "4354iojegdjss"
}   

我对这个问题的修复是在src/api/resources/posts.json中手动添加responseModel:

{
"operations": {
"GetToken": {
"httpMethod": "POST",
"uri": "token",
"summary": "Get token",
},
"responseModel": "Token"
}
}
"models": {
"Token": {
"type": "object",
"location": "json",
"properties": {
"token": {
"location": "json",
"type": "string"
}
}
}
}

如果有人知道更好的修复方法，请评论。
