JSON回應TypeError-'“資料”引數必須是字串型別'

我試圖獲取訪問令牌的 API 為我提供了以下說明（您可以在https://developers.finove.com.br/authentication 自行檢查）：

使用您的“ClientId”和“ClientSecret”獲取訪問令牌，API 身份驗證遵循標準 Oauth 2.0 協議。

API 只接受 JSON 格式的請求，因此所有請求都必須包含標頭“Content-Type: application/json”。

引數在body上：

clientId和clientSecret作為字串

回應 200 將包含訪問令牌，如下所示：

{

訪問令牌：“eyJhbGciOiJSUz...”

}

對，所以我使用以下函式向 API 發布 JSON 請求，獲取回應并獲取“accessToken”值。

<?php
// ignore the $order because its not used in the function, just passed
private function finove_auth($order){ 
        
    $authurl = 'https://api.finove.com.br/api/auth/authenticate';
    $client_id = $this->apiId;
    $client_secret = $this->apiSecret; 

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $authurl);
    curl_setopt($ch, CURLOPT_POST, TRUE);
    curl_setopt($ch, CURLOPT_HTTPHEADER, 'Content-Type: application/json');
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_POSTFIELDS, array(
            'clientId'      => $client_id,
            'clientSecret'  => $client_secret,
    ));

    $data = curl_exec($ch);

        if ( curl_errno( $ch ) ){
            // for printing on console and allowing me to check whats happening
            echo 'Error: ' . curl_error( $ch );
            return $this->finove_payment_processing( $order );
        }
        else {
            curl_close($ch);

            $auth_string = json_decode($data, true);
            print_r($auth_string); // to check the response on the console

            $this->finove_payment_processing( $order );
        }        
}

但是有些東西不起作用。在控制臺上，它回傳了我兩件事。首當其沖

Fixed malformed JSON. Original:

第二個是：

    array(7) {
      ["name"]=>
      string(9) "TypeError"
      ["message"]=>
      string(112) "The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received undefined"
      ["errors"]=>
      array(0) {
      }
      ["table"]=>
      string(0) ""
      ["constraint"]=>
      string(0) ""
      ["paramName"]=>
      string(0) ""
      ["stack"]=>
      string(585) "TypeError [ERR_INVALID_ARG_TYPE]: The "data" argument must be of type string or an instance of Buffer, TypedArray, or DataView. Received undefined

    }

無法弄清楚我做錯了什么，但它看到 clientId 和 ClientSecret 沒有按應有的方式發送。

uj5u.com熱心網友回復：

以下代碼有效：

<?php
private function finove_auth(){
    
// Get the id and secret values
    $clientId = $this->finoveID; 
    $clientSecret =  $this->finoveSecret;       
    $url = "https://api.finove.com.br/api/auth/authenticate";

// encode to json
    $data = array("clientId" => "$clientId", "clientSecret" => "$clientSecret");                                                                    
    $data_string = json_encode($data);   

    // begin the request
    $curl = curl_init();

    curl_setopt_array($curl, [ // request properties
        CURLOPT_URL => $url,
        CURLOPT_RETURNTRANSFER => true,
        CURLOPT_ENCODING => "",
        CURLOPT_MAXREDIRS => 10,
        CURLOPT_TIMEOUT => 30,
        CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
        CURLOPT_CUSTOMREQUEST => "POST",
        CURLOPT_POSTFIELDS => $data_string,
        CURLOPT_HTTPHEADER => [
        "Content-Type: application/json"
        ],
    ]);
    
    $response = curl_exec($curl); // execute the request
    $err = curl_error($curl); // get error if occur
    
    curl_close($curl); // close the request
    
    if ($err) {
        print_r("cURL Error #:" . $err); // print error to log
    } else {
        print_r($response); // print value to log
    }
  
}

它發現問題在于我沒有將資訊放入陣列中并正確使用 Json_decode() 。使用 Insomnia 應用程式：https ://insomnia.rest檢查來自 API 的 JSON 回應也確實有幫助。
