Question

我有一个连接到页面的cURL脚本：

<?php 
// create curl resource 
$ch = curl_init(); 

// set url 
curl_setopt($ch, CURLOPT_URL, "example.com"); 

//return the transfer as a string 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

// $output contains the output string 
$output = curl_exec($ch); 

// close curl resource to free up system resources 
curl_close($ch);      
?>

该页面的输出如下：

{
  "status" : "fail",
  "data" : {
    "error_message" : "Destination address 37428963298746238 is invalid for Network=BTC."
  }
}

如何使用PHP将“error_message”传递给$error_message？

Answer 1

你可能会收到这样的错误：

$ch = curl_init(); 

// set url 
curl_setopt($ch, CURLOPT_URL, "example.com"); 

//return the transfer as a string 
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

// $output contains the output string 
$output = curl_exec($ch); 

// close curl resource to free up system resources 
curl_close($ch);   
$error = json_decode($output);   
dd($error);
?>

Answer 2

    // create curl resource 
    $ch = curl_init(); 

    // set url 
    curl_setopt($ch, CURLOPT_URL, "example.com"); 

    //return the transfer as a string 
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); 

    // $output contains the output string 
    $output = curl_exec($ch); 

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

    // close curl resource to free up system resources 
    curl_close($ch);

这可能会对您有所帮助：将您的输出传递给json_decode

<?php

$json = '{
  "status" : "fail",
  "data" : {
    "error_message" : "Destination address 37428963298746238 is invalid for Network=BTC."
  }
}';




$obj = json_decode($json);



foreach($obj as $value){

echo $value->error_message;

}

?>
