Question

我正在尝试从API获取数据，为此我使用的是php curl。

我的API数据如下所示：

{"COLUMNS":["COCD","CONAME","KINDOFACCOUNT","ACCOUNTCODE","ACCOUNTNAME","TELNO","FAX","ADDR","OPENINGBALANCE","DR_AMT","CR_AMT","VOUCHERDATE","SETTLEMENT_NO","CTRCODE","CTRNAME","TRANS_TYPE","VOUCHERNO","NARRATION","BILLNO","CHQNO","EXPECTED_DATE","TRADING_COCD","PANNO","EMAIL","MANUALVNO","BOOKTYPECODE","BILL_DATE","MKT_TYPE","GROUPCODE","BRSFLAG","SETL_PAYINDATE","LAST2SETL","ACCOUNTCODE1","GATEWAYID","PUNCH_TIME","TRANS_TYPE1"],"DATA":[["MCX","","PARTY","TT3405","ANTHONIRAJ P","","","","0","","","","","","","","","","","","","","","","","3","","","","","","","TT3405","","",""],["MCX","","PARTY","TT3405","ANTHONIRAJ P","","","","0","","","","","","","","","","","","","","","","","3","","","","","","","TT3405","","",""],["NSE_FNO","","PARTY","TT3405","ANTHONIRAJ P","","","","0","","","","","","","","","","","","","","","","","3","","","","","","","TT3405","","",""],["NSE_FNO","","PARTY","TT3405","ANTHONIRAJ P","","","","0","","","","","","","","","","","","","","","","","3","","","","","","","TT3405","","",""],["NSE_FNO","","PARTY","TT3405","ANTHONIRAJ P","","","","0","0.00","500.00","","0","0","","OP","0","OPENING BALANCE","0","0","","NSE_FNO","","","0","3","","","","","","","TT3405","","",""],["MCX","","PARTY","TT3405","ANTHONIRAJ P","","","","0","0.00","1192.77","","0","0","","OP","0","OPENING BALANCE","0","0","","MCX","","","0","3","","","","","","","TT3405","","",""]]}

我能够获取数组，即所有COLUMNS名称，但当我尝试仅获取COCD列时，它说：注意：尝试获取非对象的属性

我的代码如下：

<?php
  $url = 'http://myapi.cfm';
  $curl = curl_init();

  curl_setopt_array($curl, array(
      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 => "",
      CURLOPT_HTTPHEADER => array(
        "accept: application/json",
        "cache-control: no-cache",
        "content-type: application/json"
       ),));

  $response = curl_exec($curl);
  $err = curl_error($curl);
  curl_close($curl);

  if ($err) {
      echo "cURL Error #:" . $err;
  } else {
      $characters = json_decode($response, true);
      print_r ($characters['COLUMNS']);

      foreach ($characters as $character) {
         print_r ($character->CONAME . '<br>');
          }
       }
?>

请帮助，我现在很长时间都在寻找答案。

以下是翻译此数据的一种方法......

// Standard JSON decode, no `true` second parameter
$source = json_decode('{"COLUMNS":["COCD","CONAME","KINDOFACCOUNT","ACCOUNTCODE","ACCOUNTNAME","TELNO","FAX","ADDR","OPENINGBALANCE","DR_AMT","CR_AMT","VOUCHERDATE","SETTLEMENT_NO","CTRCODE","CTRNAME","TRANS_TYPE","VOUCHERNO","NARRATION","BILLNO","CHQNO","EXPECTED_DATE","TRADING_COCD","PANNO","EMAIL","MANUALVNO","BOOKTYPECODE","BILL_DATE","MKT_TYPE","GROUPCODE","BRSFLAG","SETL_PAYINDATE","LAST2SETL","ACCOUNTCODE1","GATEWAYID","PUNCH_TIME","TRANS_TYPE1"],"DATA":[["MCX","","PARTY","TT3405","ANTHONIRAJ P","","","","0","","","","","","","","","","","","","","","","","3","","","","","","","TT3405","","",""],["MCX","","PARTY","TT3405","ANTHONIRAJ P","","","","0","","","","","","","","","","","","","","","","","3","","","","","","","TT3405","","",""],["NSE_FNO","","PARTY","TT3405","ANTHONIRAJ P","","","","0","","","","","","","","","","","","","","","","","3","","","","","","","TT3405","","",""],["NSE_FNO","","PARTY","TT3405","ANTHONIRAJ P","","","","0","","","","","","","","","","","","","","","","","3","","","","","","","TT3405","","",""],["NSE_FNO","","PARTY","TT3405","ANTHONIRAJ P","","","","0","0.00","500.00","","0","0","","OP","0","OPENING BALANCE","0","0","","NSE_FNO","","","0","3","","","","","","","TT3405","","",""],["MCX","","PARTY","TT3405","ANTHONIRAJ P","","","","0","0.00","1192.77","","0","0","","OP","0","OPENING BALANCE","0","0","","MCX","","","0","3","","","","","","","TT3405","","",""]]}');

// Loop over each row and turn it into assoc array
foreach( $source->DATA as &$data )
{
  $data = array_combine( $source->COLUMNS, $data );
}

// Get just the COCD column
print_R( array_column( $source->DATA, 'COCD' ) );

//  Array
//  (
//    [0] => MCX
//    [1] => MCX
//    [2] => NSE_FNO
//    [3] => NSE_FNO
//    [4] => NSE_FNO
//    [5] => MCX
//  )
