php post返回json修改

Question

<?php
$curl = curl_init();
curl_setopt_array($curl, array(
  CURLOPT_URL => 'https://api.xxx.com/api/pool_stats?pool_type=xxx,
  CURLOPT_RETURNTRANSFER => true,
  CURLOPT_SSL_VERIFYPEER => false,
  CURLOPT_ENCODING => '',
  CURLOPT_MAXREDIRS => 10,
  CURLOPT_TIMEOUT => 0,
  CURLOPT_FOLLOWLOCATION => true,
  CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
  CURLOPT_CUSTOMREQUEST => 'GET',
  CURLOPT_HTTPHEADER => array(
    'Authorization: Bearer ' xxxxxxxxxxxxxxxxxxx
  ),
));

$response = curl_exec($curl);

curl_close($curl);
echo $response;

打开返回数据如下
[{"country_code":"ad","country_name":"Andorra","count":102},{"country_code":"ae","country_name":"United Arab Emirates","count":539},{"country_code":"af","country_name":"Afghanistan","count":1},{"country_code":"al","country_name":"Albania","count":431},{"country_code":"am","country_name":"Armenia","count":41},{"country_code":"aq","country_name":"Antarctica","count":1},{"country_code":"ar","country_name":"Argentina","count":411},{"country_code":"at","country_name":"Austria","count":1145},{"country_code":"au","country_name":"Australia","count":7753},{"country_code":"ba","country_name":"Bosnia and Herzegovina","count":55}]

需要修改为一行一个
国家2位代码: "ad " 国家全称:"Andorra" 目前数量:102
国家2位代码: "ae " 国家全称:"United Arab Emirates" 目前数量:539
国家2位代码: "af " 国家全称:"Afghanistan" 目前数量:1

echo $response; 这里怎么写才能达到以上效果

第二个问题
同样的打开PHP返回数据如下
{"id":329859,"label":"datacenter1","login":"xxxxx","password":"xxxxxx","balance":5368033729,"balance_format":"5 GB","threads":400,"sticky_range":{"start":10000,"end":30000},"allowed_ips":["125.1.1.1","60.249.20.180"],"blocked":false,"pool_type":"datacenter","default_pool_parameters":{"countries":["us","it","jp","de"],"cities":[""],"states":[""],"zipcodes":[],"asns":["7922"],"exclude_countries":[],"exclude_asn":[],"anonymous_filter":false,"rotation_interval":10},"blocked_hosts":[]}

需要只保留 allowed_ips":["125.1.1.1","60.249.20.180"]得到以下格式
allowed_ips:
125.1.1.1
60.249.20.180

echo $response; 这里怎么写才能达到以上效果

为了帮助你解决这两个问题，我将逐步引导你如何用PHP来处理从API得到的JSON数据并格式化输出。以下是详细的解答。

第一个问题

目标: 将返回的JSON数据打印为每行一条记录，含有国家代码、国家名称及目前数量。

步骤

1. Decode JSON字符串为PHP数组。
2. 遍历该数组，将每条数据格式化为指定的输出格式。
3. 输出格式化后的字符串。

示例代码

<?php
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => 'https://api.xxx.com/api/pool_stats?pool_type=xxx',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_SSL_VERIFYPEER => false,
    CURLOPT_ENCODING => '',
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 0,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => 'GET',
    CURLOPT_HTTPHEADER => array(
        'Authorization: Bearer xxxxxxxxxxxxxxxxxxx',
    ),
));
$response = curl_exec($curl);
curl_close($curl);
// 解析JSON数据
$data = json_decode($response, true);
// 遍历数据并格式化输出
foreach ($data as $item) {
    $formatted_output = sprintf(
        '国家2位代码: "%s"  国家全称: "%s"  目前数量: %d',
        $item['country_code'],
        $item['country_name'],
        $item['count']
    );
    echo $formatted_output . PHP_EOL; // 输出每一行
}
?>

输出示例

国家2位代码: "ad"  国家全称: "Andorra"  目前数量: 102
国家2位代码: "ae"  国家全称: "United Arab Emirates"  目前数量: 539
国家2位代码: "af"  国家全称: "Afghanistan"  目前数量: 1
...

第二个问题

目标: 从返回的JSON数据中提取allowed_ips并格式化输出。

步骤

1. Decode JSON字符串为PHP数组。
2. 直接访问allowed_ips键，遍历并打印。

示例代码

<?php
$curl = curl_init();
curl_setopt_array($curl, array(
    CURLOPT_URL => 'https://api.xxx.com/api/pool_stats?pool_type=xxx',
    CURLOPT_RETURNTRANSFER => true,
    CURLOPT_SSL_VERIFYPEER => false,
    CURLOPT_ENCODING => '',
    CURLOPT_MAXREDIRS => 10,
    CURLOPT_TIMEOUT => 0,
    CURLOPT_FOLLOWLOCATION => true,
    CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
    CURLOPT_CUSTOMREQUEST => 'GET',
    CURLOPT_HTTPHEADER => array(
        'Authorization: Bearer xxxxxxxxxxxxxxxxxxx',
    ),
));
$response = curl_exec($curl);
curl_close($curl);
// 解析JSON数据
$data = json_decode($response, true);
// 输出allowed_ips
if (isset($data['allowed_ips']) && is_array($data['allowed_ips'])) {
    echo "allowed_ips:\n"; // 输出标头
    foreach ($data['allowed_ips'] as $ip) {
        echo $ip . "\n"; // 输出每一行的IP
    }
}
?>

输出示例

allowed_ips:
125.1.1.1
60.249.20.180

总结

通过使用json_decode()函数将JSON字符串转换为PHP数组，结合简单的循环和字符串格式化功能，我们可以轻松地将API返回的数据转换为所需的格式并输出。这种方式使得处理和输出JSON数据变得简单和有效。你可以根据需要调整请求参数以及URL，确保它满足你的实际需求。
