json_decode在有效的json上为空

curl json php

Ali Zia · 技术社区 · 7 年前

我的$result里有这条短信

{“meta”:{“code”:400,“message”:“Bad Request”},“error”:“需要用户id。”,“extras”:null}

$json_result = json_decode($result, true);
print_r($json_result);

无效的 . 我已经在任何地方验证了这个文本,它说它是一个有效的json。

<?php

$data = "&userId=";
$data_string = $data;
$url = 'http://apptellect.cloudapp.net/binance/api/v1/get_user_assets/';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo $result = curl_exec($ch);
echo '<hr>';
curl_close($ch);
$json_result = json_decode($result, true);
echo json_last_error_msg();
echo '<hr>';
//$json_result = json_decode( preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $result), true );
print_r($json_result);
?>

我已经解决了这个问题,请检查下面的代码

<?php
// Your code here!
$data = "&userId=";
$data_string = $data;
$url = 'http://apptellect.cloudapp.net/binance/api/v1/get_user_assets/';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo $result = curl_exec($ch);
echo '<hr>';
curl_close($ch);

// This will remove unwanted characters.
// Check http://www.php.net/chr for details
for ($i = 0; $i <= 31; ++$i) { 
    $result = str_replace(chr($i), "", $result); 
}
$result = str_replace(chr(127), "", $result);

// This is the most common part
// Some file begins with 'efbbbf' to mark the beginning of the file. (binary level)
// here we detect it and we remove it, basically it's the first 3 characters 
if (0 === strpos(bin2hex($result), 'efbbbf')) {
   $result = substr($result, 3);
}

$json_result =    json_decode($result, true);

echo json_last_error_msg();
echo '<hr>';
print_r($json_result);

?>

快乐编程

嗨,我在stackoverflow上发现: here

<?php

function removeBOM($data) {
    if (0 === strpos(bin2hex($data), 'efbbbf')) {
       return substr($data, 3);
    }
    return $data;
}

$data = "&userId=";
$data_string = $data;
$url = 'http://apptellect.cloudapp.net/binance/api/v1/get_user_assets/';
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);

$result = curl_exec($ch);
$result = removeBOM($result);
echo $result;

curl_close($ch);
$json_result = json_decode(trim($result), false);
echo json_last_error_msg();
//$json_result = json_decode( preg_replace('/[\x00-\x1F\x80-\xFF]/', '', $result), true );
print_r($json_result);
?>

你只需要在解码你的密码。你会得到一些额外的数据
