Question

美好的一天，我想使用cURL从URL获取响应，然后将数据分配给PHP变量，但即使URL有数据，我的cURL也会返回NULL值。我搜索并尝试了类似情况下的每个解决方案，但我失败了。希望有人可以帮我解决这个问题。

这是网址＆＃34; http://localhost/sample/testURL.php＆＃34;

的数据

{
  "login": {
    "error": false,
    "user": {
      "br_code": 0,
      "mem_id": 202
    }
  },
  "branch": {
    "error": false,
    "branch_info": {
      "br_id": 0,
      "br_desc": "OFFICE 1",
      "br_add": "Sample Address",
      "br_manager": "John Doe",
      "br_accronym": "",
      "br_trans_date": "2017-08-05"
    }
  },
  "accounts": {
    "error": false,
    "sl_summ": [
      {
        "sl_desc": "Sampe Account",
        "tr_date": "2017-09-04",
        "actual_balance": "100.00",
        "available_balance": "100.0"
      }
    ]
  }
}

这是我的cURL的代码，返回NULL

<?php
session_start();

$url= 'http://localhost/sample/testURL.php';
$ch = curl_init($url);

$br_code= $_SESSION["BR_CODE"];
$client_id= $_SESSION["MEM_ID"];

// set post fields
$post = [
    'br_code' => $br_code,
    'client_id' => $client_id
];

curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_POSTFIELDS, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post);

// execute!
$response = curl_exec($ch);

print_r(curl_getinfo($ch));

if(curl_errno($ch)){
    echo 'Curl error: ' . curl_error($ch);
}

// close the connection, release resources used
curl_close($ch);

$obj= json_decode($response, true);

// do anything you want with your response
var_dump($obj);          //returns NUll
var_dump($br_code);      //returns 0
var_dump($client_id);    //returns 202
?>

使用curl_getinfo（）

返回值

Array

    [url] => http://localhost/coredev_localserver/accountsummary.php
    [content_type] => text/html; charset=UTF-8
    [http_code] => 200

    [redirect_time] => 0
    [redirect_url] => 
    [primary_ip] => ::1
    [certinfo] => Array
        (
        )

    [primary_port] => 80
    [local_ip] => ::1
    [local_port] => 52160
)
NULL           
int(0)        
int(202)

我的cURL有什么问题？
