多个curl json和json打印 [英] Multiple curl json and json print

问题描述

我想通过curl访问多个URL并打印子输出。我已经看到了：多个cURL并输出JSON？，但我无法使其正常工作...

I want to access multiples urls via curl and print the son output. I've seen this: multiple cURL and output JSON? but I`am not able make it work anyway...

我的代码：

<?php
$urls = Array(
 'URLtoJSON1',
 'URLtoJSON1'
);

for($i = 0; $i < 3; $i++) {
  $curl[$i] = curl_init($urls);
  curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
  curl_setopt($curl, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
  curl_setopt($curl, CURLOPT_USERPWD, "YYY:XXX");
  curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
  curl_setopt($curl, CURLOPT_POST, true);
  curl_setopt($curl, CURLOPT_POSTFIELDS, $curl_post_data);
  $curl_response[$i] = curl_exec($curl);
  curl_close($curl);

  $data = json_decode($curl_response[$i]);
  $name[$i] = $data->fullDisplayName;
  $datum[$i] = $data->timestamp;
  $result[$i] = $data->result;

}

// here I`d love to be able echo output $name[URLtoJSON], etc...
?>

感谢您的帮助。

推荐答案

您可以创建一个 foreach 循环，而不是执行 for 循环通过执行 foreach（$ urls为$ key => $ url）遍历 $ urls 数组。 $ key 将保存数组的索引（从0开始），而 $ url 将保存URL。

Instead of doing a for loop, you can make a foreach loop that iterates over your $urls array by doing foreach ($urls as $key=>$url). $key will hold the index of the array (starting at 0) and $url will hold the URL.

结果代码如下：

$urls = Array(
    'URLtoJSON1',
    'URLtoJSON2'
);

foreach ($urls as $key=>$url) {
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $url); 
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
    curl_setopt($ch, CURLOPT_USERPWD, "YYY:XXX");
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $ch_post_data);
    $ch_response = curl_exec($ch);
    curl_close($ch);

    $data = json_decode($ch_response);
    $name[$key] = $data->fullDisplayName;
    $datum[$key] = $data->timestamp;
    $result[$key] = $data->result;
}

现在，如果要访问 $ name 第一个URL，您只需执行 $ echo $ name [0];

Now if you want to access $name of the first URL, you would just do $echo $name[0];

您也可以通过类似的方式访问 $ datum 或 $ result 。

You can also access $datum or $result in a similar way.
