如何在cURL POST请求中使用数组 [英] How do I use arrays in cURL POST requests

问题描述

我想知道如何让这个代码支持数组？目前图像数组只是发送第一个值。

I am wondering how do I make this code support arrays? At the moment the images array only seems to send the first value.

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);
?>

这是api收到的资料

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" 
                               } 
         }

图片[] ？

推荐答案

做类似的操作：

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

b $ b

所以，你可以使用的整个代码是：

So, the entire code that you could use would be:

<?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
$field_string = http_build_query($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);
?>
