如何在cURL POST请求中使用数组

我想知道如何使此代码支持数组？目前，images数组似乎只发送第一个值。

这是我的代码：

<?php
//extract data from the post
extract($_POST);
//set POST variables
$url = 'http://api.example.com/api';
$fields = array(
            'username' => "annonymous",
            'api_key' => urlencode("1234"),
            'images[]' => urlencode(base64_encode('image1')),
            'images[]' => urlencode(base64_encode('image2'))
        );
//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
//execute post
$result = curl_exec($ch);
echo $result;
//close connection
curl_close($ch);
?>

这就是在api上收到的

VAR: username = annonymous
VAR: api_key = 1234
VAR: images = Array
array(3) { 
         ["username"]=> string(10) "annonymous" 
         ["api_key"]=> string(4) "1234" 
         ["images"]=> array(1) { // this should contain 2 strings :( what is happening?
                               [0]=> string(8) "aW1hZ2Uy" 
                               } 
         }

中的第二个值发生了什么images[]？

回答：

您只是错误地创建了数组。您可以使用http_build_query：

$fields = array(
            'username' => "annonymous",
            'api_key' => urlencode("1234"),
            'images' => array(
                 urlencode(base64_encode('image1')),
                 urlencode(base64_encode('image2'))
            )
        );
$fields_string = http_build_query($fields);

因此，您可以使用的整个代码为：

<?php
//extract data from the post
extract($_POST);
//set POST variables
$url = 'http://api.example.com/api';
$fields = array(
            'username' => "annonymous",
            'api_key' => urlencode("1234"),
            'images' => array(
                 urlencode(base64_encode('image1')),
                 urlencode(base64_encode('image2'))
            )
        );
//url-ify the data for the POST
$fields_string = http_build_query($fields);
//open connection
$ch = curl_init();
//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, 1);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);
//execute post
$result = curl_exec($ch);
echo $result;
//close connection
curl_close($ch);
?>
