Question

好日子！我有一个小问题，PHP访问json数组中的第3和第4级数据。根据下面的json数据，我有“servicelist”，从这个servicelist我有一堆信息，如服务器的IP地址和在其下运行的进程。

我的问题是如何使用php循环遍历此IP地址及其下的服务值。

json数据如下：

{
  "format_version": 0,
  "result": {
    "query_time": 1480964905000,
    "cgi": "statusjson.cgi",
    "user": "nagiosadmin",
    "query": "servicelist",
    "query_status": "released",
    "program_start": 1480936959000,
    "last_data_update": 1480964898000,
    "type_code": 0,
    "type_text": "Success",
    "message": ""
  },
  "data": {
    "selectors": {
      "hostgroup": "Premium"
    },
    "servicelist": {
      "104.11.2.25": {
        "DISK": 2,
        "L2TP": 2,
        "LOAD": 2,
        "OPENVPN TCP": 2,
        "OPENVPN UDP": 2,
        "PING": 2,
        "PPTP": 2,
        "PROCESS": 2,
        "USERS": 2,
        "XL2TPD": 2
      },
      "104.44.13.17": {
        "DISK": 2,
        "L2TP": 2,
        "LOAD": 2,
        "OPENVPN TCP": 2,
        "OPENVPN UDP": 2,
        "PING": 4,
        "PPTP": 2,
        "PROCESS": 2,
        "USERS": 2,
        "XL2TPD": 2
      },
      "14.244.15.16": {
        "DISK": 2,
        "L2TP": 2,
        "LOAD": 2,
        "OPENVPN TCP": 2,
        "OPENVPN UDP": 2,
        "PING": 4,
        "PPTP": 2,
        "PROCESS": 2,
        "USERS": 2,
        "XL2TPD": 2
      }
   }
   }
}

我的不完整的PHP代码如下：

    <?php

$username = "thisuser";
$password = "this password";
$url = "http://nagios.services.com/nagios/cgi-bin/statusjson.cgi?query=servicelist&hostgroup=Servers&hoststatus=up+down+unreachable+pending&servicestatus=ok+warning+critical+unknown+pending";
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
$jsonData = json_decode(curl_exec($ch));
curl_close($ch);

foreach($jsonData->data as $thisData){
    foreach($thisData->servicelist as $values)
    {
        foreach($values as $result){
            echo $result->LOAD;
        }
    }  
}

?>

基本上我想要的是将信息放在一个表中，如： Sample HTML Table

你可以试试这段代码：

<?php

     $username = "thisuser";
     $password = "this password";
     $url = "http://nagios.services.com/nagios/cgi-bin/statusjson.cgi?query=servicelist&hostgroup=Servers&hoststatus=up+down+unreachable+pending&servicestatus=ok+warning+critical+unknown+pending";

     $ch = curl_init();

     curl_setopt($ch, CURLOPT_URL, $url);
     curl_setopt($ch, CURLOPT_USERPWD, "$username:$password");
     curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
     curl_setopt($ch, CURLOPT_BINARYTRANSFER, true);
     curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);

     $jsonData = json_decode(curl_exec($ch), true);
     curl_close($ch);

     foreach($jsonData['data']['servicelist'] as $ip => $service_list) {
        echo "<p>IP Address: {$ip}, Load: {$service_list['LOAD']}</p>";
    }

?>

修改

<?php $username = "thisuser"; $password = "this password"; $url = "http://nagios.services.com/nagios/cgi-bin/statusjson.cgi?query=servicelist&hostgroup=Servers&hoststatus=up+down+unreachable+pending&servicestatus=ok+warning+critical+unknown+pending"; $ch = curl_init(); curl_setopt($ch, CURLOPT_URL, $url); curl_setopt($ch, CURLOPT_USERPWD, "$username:$password"); curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); curl_setopt($ch, CURLOPT_BINARYTRANSFER, true); curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1); $jsonData = json_decode(curl_exec($ch), true); curl_close($ch); foreach($jsonData['data']['servicelist'] as $ip => $service_list) { echo "<p>IP Address: {$ip}, Load: {$service_list['LOAD']}</p>"; } $ip_status = array( '1' => 'Pending', '2' => 'OK', '4' => 'Warning', '8' => 'Unknown', '16' => 'Critical' ); ?> <html> <head> <title>IP Data</title> <style> table { border-collapse: collapse; } table th, table tr td { text-align: center; border: 1px solid #ccc; text-transform: uppercase; padding: 10px 20px; } </style> </head> <body> <table> <thead> <th>IP Address</th> <th>Load</th> <th>OpenVPN TCP</th> <th>OpenVPN UDP</th> <th>Users</th> <th>L2TP</th> <th>PPTP</th> <th>XL2TPD</th> </thead> <tbody> <?php if(!empty($jsonData['data']['servicelist'])): ?> <?php foreach($jsonData['data']['servicelist'] as $ip => $service_list): ?> <tr> <td><?= $ip ?></td> <td><?= $ip_status[$service_list['LOAD']] ?></td> <td><?= $ip_status[$service_list['OPENVPN TCP']] ?></td> <td><?= $ip_status[$service_list['OPENVPN UDP']] ?></td> <td><?= $ip_status[$service_list['USERS']] ?></td> <td><?= $ip_status[$service_list['L2TP']] ?></td> <td><?= $ip_status[$service_list['PPTP']] ?></td> <td><?= $ip_status[$service_list['XL2TPD']] ?></td> </tr> <?php endforeach; ?> <?php endif; ?> </tbody> </table>
