我正在访问“ConnectWise”的 API。数据为 JSON 格式。我能够通过 PHP 将数据解析成表格。但是，JSON 中的空字段会导致未定义索引。例如，某些没有网站或地址的项目会发生这种情况。其余的都很好。任何帮助或输入将不胜感激。

这是我从 Connectwise 获取数据的代码：

function get_companies(){

   $curl = curl_init();
   curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, 1);
   curl_setopt($curl, CURLOPT_URL, "https://api- 
   na.myconnectwise.net/v4_6_release/apis/3.0/company/companies");
   curl_setopt($curl, CURLOPT_RETURNTRANSFER, 1 );
   curl_setopt($curl, CURLOPT_HTTPHEADER, array(

  "Authorization: Basic (OUR KEY)",

   'Content-type: application/json'

       ));

$result = curl_exec($curl);
curl_close($curl);
$decoded =  json_decode($result,true);
return $decoded;
}

并显示数据：

function list_all_accounts(){

    $accounts = get_companies();

    if ( !empty ($accounts)){
            foreach ($accounts as $account) {

                {
        echo "
                    </td>
                    <td>
                        $account[id]
                    </td>
                    <td>
                        $account[name]
                    </td>
                    <td>
                        $account[addressLine1]
                    </td>
                    <td>
                         $account[phoneNumber]
                    </td>
                    <td>
                         $account[website]
                    </td>   
                    <td>
                        $account[name]
                    </td>                       
                    </tr>";
            }
    }
   }
 }

根据您的评论，您在 HTML 中使用的某些属性可能不是您收到的 JSON 的一部分。这意味着您正在访问未设置的数组索引，例如使用$account[website].

我看到了两种解决方案：

  1. 仅在数组中设置数据时才输出数据：

    echo '<td>'.(isset($account['website']) ? $account['website'] : '').'</td>';

  2. 使用具有所有值的默认值的数组作为$account数组的基础并合并它们：

    $base = [
    'website' => 'no website',
    'phoneNumber' => '',
];

foreach ($accounts as $account) {
    // this will override all elements of $base with them of $account,
    // but only if they are present in $account
    $account = array_merge($base, $account);

    // ... your output here ...
}

json_decode()和https://jsonlint.com/都抱怨第 95 行和第 194 行的值后面的逗号。删除它们使其成为有效的 json，之后只要您记得引用关联数组的键值，您的代码就会工作。

我删除了 json 中的两个有问题的逗号并保存为一个文件，然后在数组中添加了对键值的引用，最后删除了 HTML 表等内容（我只是在命令行上运行它以查看输出） . 应该很容易装回去...

<?php

function get_companies() {
    $j = file_get_contents("json.json");
    $jd = json_decode($j, true);
    return $jd;
}

$accounts = get_companies();
if (!empty($accounts)) {
    foreach ($accounts as $account) {
        echo  "\n".$account['id'] . "
              " . $account['name'] . "
              " . $account['addressLine1'] . "
              " . $account['phoneNumber'] . "
              " . $account['website'] . "
              " . $account['name']."\n\n";
    }
}
?>
