php curl get json并解码然后显示，失败不显示

Question

你好，我的老师已经给了我这个星期的工作，我需要从网址获取我的json数据并使用json_decode将其显示为php，我使用url访问的php json文件显示json数组的歌曲并且工作很好，我复制了我的老师卷曲示例来访问网址，但它没有显示我做错了什么？

编辑：我确实需要输入密码和用户名来访问网址，所以我按照说明更改了代码，但仍然没有显示，我更改了密码和用户名以确保安全，但格式和长度相同

<?php
$username = "2foobar90";
$password = "123456";
// Initialise the cURL connection
$connection = curl_init();

curl_setopt($connection, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($connection, CURLOPT_USERPWD, $username . ":" . $password);  
// Specify the URL to connect to - DOUBLE CLICK link to test 
curl_setopt($connection, CURLOPT_URL, "https://edward2.solent.ac.uk/~martine/year3/hits.php?artist=David+Bowie");


// This option ensures that the HTTP response is *returned* from curl_exec(),
// (see below) rather than being output to screen.  
curl_setopt($connection,CURLOPT_RETURNTRANSFER,1);

// Do not include the HTTP header in the response.
curl_setopt($connection,CURLOPT_HEADER, 0);

// Actually connect to the remote URL. The response is 
// returned from curl_exec() and placed in $response.
$response = curl_exec($connection);

// Close the connection.
curl_close($connection);

$data = json_decode($response, true);

for($i=0; $i<count($data); $i++)
{
    echo "Song id " . $data[$i]["songid"] . " " .
         "Title " . $data[$i]["title"] . " " .
         "Artist " . $data[$i]["artist"] . " " .
         "Chart position " . $data[$i]["chart"] . "<br/>";
}
?>

该链接需要基本身份验证。单击链接时，您的浏览器会记住您的用户名/密码。您可以使用chrome检查器查看请求标头。

1. 点击链接
2. 打开浏览器检查器
3. 点击网络部分
4. 查找文件
5. 您可以在“请求标题”下查看授权数据



如果您想使用curl授权，请添加：

for(var i=1; i<=theLastRow; i++)
{
  //table 1
  if(sheetToMoveFrom.getRange(i,columnNumberToWatch1).getValue() == valueToWatchYES)
  {
    rangeToCopy=sheetToMoveFrom.getRange(i,1,1,14);
    var valuesToCopy=rangeToCopy.getValues();
    valuesToCopy.splice(5,2);
    valuesToCopy.splice(9,1);
    rangeToReceiveCopy=sheetToMoveTo1.getRange(theFreeRow1,1,1,11);
    rangeToReceiveCopy.setValues(valuesToCopy);
    theFreeRow1++;
  }
  //table 2
  if(sheetToMoveFrom.getRange(i,columnNumberToWatch21).getValue() == valueToWatchYES || sheetToMoveFrom.getRange(i,columnNumberToWatch22).getValue() == valueToWatchYES || sheetToMoveFrom.getRange(i,columnNumberToWatch23).getValue() == valueToWatchYES)
  {
    rangeToCopy=sheetToMoveFrom.getRange(i,1,1,14);
    var valuesToCopy=rangeToCopy.getValues();
    valuesToCopy.splice(7,2);
    valuesToCopy.splice(9,1);
    rangeToReceiveCopy=sheetToMoveTo2.getRange(theFreeRow2,1,1,13);
    rangeToReceiveCopy.setValues(valuesToCopy);
    theFreeRow2++;
  }
  //table 3
  if(sheetToMoveFrom.getRange(i,columnNumberToWatch3).getValue() == valueToWatchYES)
  {
    rangeToCopy=sheetToMoveFrom.getRange(i,1,1,14);
    var valuesToCopy=rangeToCopy.getValues();
    valuesToCopy.splice(5,2);
    valuesToCopy.splice(9,1);
    rangeToReceiveCopy=sheetToMoveTo3.getRange(theFreeRow3,1,1,11);
    rangeToReceiveCopy.setValues(valuesToCopy);
    theFreeRow3++;
  }
 }
