我得到这个错误帮助我这个我用trson解码没有帮助所以我在哪里错误

Answer 1

$ response有你无法使用的JSON数据和PHP。运算符来获取其密钥。 - 转换为数组 - 访问密钥

因为您的回答是这样的

{ "success": true, "challenge_ts": "2017-02-09T12:18:22Z", "hostname": "localhost" }

做这样的事情：

$response = file_get_contents("https://www.google.com/recaptcha/api/siteverify?secret='PRIVATE'&response=" . $captcha . '&remoteip=' . $_SERVER['REMOTE_ADDR']);
// Convert json to array
$response = ($response) ? json_decode($response, true) : [];
// If array not empty then perform your logic
if ($res) {
   if (!$captcha || $response['success'] == false) {
    echo "Your CAPTCHA response was wrong";
    exit ; 
  } else { 
   // your code 
     .....
      ....
  }
}

这样可行。

Answer 2

使用json_decode()

$response = json_decode($response);

并像这样检查

if (!$captcha || $response->success == false) {
