Basic方法的另一种方法是:

$curl = curl_init();

$public_key = "public_key";
$private_key = "private_key";

curl_setopt_array($curl, array(
CURLOPT_URL => "https://url.endpoint.co/login",
CURLOPT_RETURNTRANSFER => true,
CURLOPT_ENCODING => "",
CURLOPT_MAXREDIRS => 10,
CURLOPT_TIMEOUT => 0,
CURLOPT_FOLLOWLOCATION => true,
CURLOPT_HTTP_VERSION => CURL_HTTP_VERSION_1_1,
CURLOPT_CUSTOMREQUEST => "POST",
CURLOPT_HTTPHEADER => array(
"Content-Type: application/json",
"Authorization: Basic ".base64_encode($public_key.":".$private_key)
),
));
$response = curl_exec($curl);
curl_close($curl);
echo $response;

最简单、最自然的方法是直接使用CURL。

这对我来说很管用:

<?php
$login = 'login';
$password = 'password';
$url = 'http://your.url';
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_RETURNTRANSFER,1);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_USERPWD, "$login:$password");
$result = curl_exec($ch);
curl_close($ch);  
echo($result);

市面上有多种REST框架。我强烈建议你看看Slim mini Framework for PHP 以下是其他一些公司的名单。

Michael Dowling的《Guzzle》便是一个不错的选择。除了优雅的接口、异步调用和符合PSR，它还使REST调用的身份验证头非常简单:

// Create a client with a base URL
$client = new GuzzleHttp\Client(['base_url' => 'http://myservices.io']);

// Send a request to http://myservices.io/status with basic authentication
$response = $client->get('/status', ['auth' => ['username', 'password']]);

去看医生。

你想要的是:

curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);  

Zend有一个REST客户端和zend_http_client，我确信PEAR有某种包装器。 但是你自己做也很容易。

所以整个请求看起来是这样的:

$ch = curl_init($host);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('Content-Type: application/xml', $additionalHeaders));
curl_setopt($ch, CURLOPT_HEADER, 1);
curl_setopt($ch, CURLOPT_USERPWD, $username . ":" . $password);
curl_setopt($ch, CURLOPT_TIMEOUT, 30);
curl_setopt($ch, CURLOPT_POST, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS, $payloadName);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, TRUE);
$return = curl_exec($ch);
curl_close($ch);

如果授权类型是基本认证，并且发布的数据是json，那么这样做

<?php

$data = array("username" => "test"); // data u want to post                                                                   
$data_string = json_encode($data);                                                                                   
 $api_key = "your_api_key";   
 $password = "xxxxxx";                                                                                                                 
$ch = curl_init(); 
curl_setopt($ch, CURLOPT_URL, "https://xxxxxxxxxxxxxxxxxxxxxxx");    
curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 20);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");  
curl_setopt($ch, CURLOPT_POST, true);                                                                   
curl_setopt($ch, CURLOPT_POSTFIELDS, $data_string);                                                                  
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);     
curl_setopt($ch, CURLOPT_USERPWD, $api_key.':'.$password);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC); 
curl_setopt($ch, CURLOPT_HTTPHEADER, array(   
    'Accept: application/json',
    'Content-Type: application/json')                                                           
);             

if(curl_exec($ch) === false)
{
    echo 'Curl error: ' . curl_error($ch);
}                                                                                                      
$errors = curl_error($ch);                                                                                                            
$result = curl_exec($ch);
$returnCode = (int)curl_getinfo($ch, CURLINFO_HTTP_CODE);
curl_close($ch);  
echo $returnCode;
var_dump($errors);
print_r(json_decode($result, true));
