authorize.net json返回多余的字符 [英] authorize.net json return extra characters

问题描述

我有这个代码

$ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, $url);
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  curl_setopt($ch, CURLOPT_HTTPHEADER, Array("'Content-Type: application/json; charset=utf-8'"));
  curl_setopt($ch, CURLOPT_HEADER, 0);
  curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($data_str));
  curl_setopt($ch, CURLOPT_POST, 1);
  curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
  $xmlresult = curl_exec($ch);
  $xmlError = $xmlresult;
  $json = json_decode($xmlresult, true);

我进入json但无法转换的答案，因为开头的答案是多余的字符，请参见示例

The answer I get into json but I could not convert because the in the beginning answer is, extra characters See example

п»ї{"customerPaymentProfileIdList":[],"customerShippingAddressIdList":[],"validationDirectResponseList":[],"messages":{"resultCode":"Error","message":[{"code":"E00039","text":"A duplicate record with ID 39223758 already exists."}]}}

由于多余的字符，我无法json_decode字符串.该怎么办?

Because of the extra characters I can not json_decode string. What can be done?

推荐答案

在为我的库开发时，我遇到了相同的问题访问其JSON API .在处理响应的代码中，我不得不剥离这些字符，以便正确地将字符串解码为JSON.

I encountered the same issue when developing my library for accessing their JSON API. In the code that handles the response I had to strip those characters out in order to properly decode the string as JSON.

第113行:

$this->responseJson = preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $responseJson);
