count(): Parameter must be an array or an object that implements Countable at LINE 428 error in PHP

Question

我正在尝试将一些数据保存到 API，但我一直收到此错误 count(): Parameter must be an array or an object that implements Countable at LINE 428, API 正在发布数据以接受对象数组，但在我的数据子变量中抛出上述错误..

请帮忙？

$children = '[{"child_name" => "Mmansa" , "child_dob" => "jdhjdhjd" }]'; 

$data = [
      'quote_id' => $quote,
      'country_residence' => $resd,
      'physical_address' => $physical,
      'children' => $children,
];

Post 通过 Curl

$res = $this->global_Curl($data, 'api/travel/save-policy-meta');

卷曲函数

 public function global_Curl($data, $url)
    {
        $ch = curl_init();
        curl_setopt($ch, CURLOPT_URL, (env('API_ENDPOINT_NGINX_IP') . '/' . $url));
        curl_setopt($ch, CURLOPT_HEADER, 0);
        curl_setopt($ch, CURLOPT_POSTFIELDS, $data);
        curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
        curl_setopt($ch, CURLOPT_FRESH_CONNECT, TRUE); 
        $response = json_decode(curl_exec($ch));
        curl_close($ch);
        return $response;
    }

API

所需数据

{
"quote_id":136,
"country_residence":"Japan",
"physical_address":"Tokyo",
"children":[
    {"child_name":"abc","child_dob":"23-05-2015"}
  ]
}

Answer 1

您的 API 需要 JSON 请求，您在 CURLOPT_POSTFIELDS 中将其作为数组发送，并且还有一个字段无效 JSON 字符串

此字符串无效 JSON

'[{"child_name" => "Mmansa" , "child_dob" => "jdhjdhjd" }]'

应该是这样的

'[{"child_name" : "Mmansa" , "child_dob" : "jdhjdhjd" }]'

这里不用写JSON字符串，可以用json_encode()方法将数组转成JSON字符串

改变这个

$children[] = ["child_name" => "Mmansa" , "child_dob" => "jdhjdhjd"]; 

$data = [
  'quote_id' => $quote,
  'country_residence' => $resd,
  'physical_address' => $physical,
  'children' => $children,
];

并试试这个代码

public function global_Curl($data, $url)
{
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, (env('API_ENDPOINT_NGINX_IP') . '/' . $url));
    curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type:application/json'));
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data));
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_FRESH_CONNECT, TRUE); 
    $response = json_decode(curl_exec($ch));
    curl_close($ch);
    return $response;
}
