使用PHP cURL通过REST API获取JSON

我想使用PHP cURL通过REST API检索JSON数据。

使用本文中的PHP代码,我能够通过URL绕过Spring Security页面:

https://<host>/appserver/j_spring_security_check

但是,JSON存在于此URL中,我想要获取它:

https://<host>/appserver/portal/api/1.0/apps

这是我用来自动登录的PHP代码,我尝试使用file_get_contents(url)但它失败了,只有以下代码用于确认登录。

<?php
function login(){
    $headers[]      = "Accept: */*";
    $headers[]      = "Connection: Keep-Alive";
    $headers[]      = "Content-type: application/x-www-form-urlencoded;charset=UTF-8";
    $data           = "j_username=admin&j_password=demoserver";
    $data           = rtrim($data, "&");
    global $sessionid;
    $sessionid      = dirname(__FILE__).'/cookie2.txt'
    $ch                 = curl_init(); 
    $options = array(
        CURLOPT_REFERER             => "https://<host>/appserver/portal/login",
        CURLOPT_HTTPHEADER          => $headers,
        CURLOPT_COOKIEFILE          => $sessionid,
        CURLOPT_COOKIEJAR           => $sessionid,
        CURLOPT_URL                 => "https://<host>/appserver/j_spring_security_check",
        CURLOPT_SSL_VERIFYHOST      => 0,
        CURLOPT_SSL_VERIFYPEER      => false,
        CURLOPT_POST                => true,
        CURLOPT_POSTFIELDS          => $data,
        CURLOPT_HEADER              => true,
        CURLOPT_USERAGENT           => 'Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:51.0) Gecko/20100101 Firefox/51.0');
    curl_setopt_array($ch, $options);
    $content            = curl_exec($ch);
    curl_close($ch);
}
login();
$text = file_get_contents($sessionid);
preg_match('/\w{32}/u', $text, $match);
$jsession = implode($match);

    $headers1[]         = "Accept: */*";
    $headers1[]         = "Connection: Keep-Alive";
    $headers1[]         = "Content-type: application/json";
    $headers1[]         = "Cookie: JSESSIONID=".$jsession;
$url = 'https://<host>/appserver/portal/api/1.0/apps';
$ch2 = curl_init();
curl_setopt($ch2, CURLOPT_URL, $url);
curl_setopt($ch2, CURLOPT_HTTPHEADER, $headers1);
curl_setopt($ch2, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch2, CURLOPT_COOKIEFILE, $sessionid);
curl_setopt($ch2, CURLOPT_COOKIEJAR, $sessionid);
curl_setopt($ch2, CURLOPT_HTTPGET, 1);
$result = curl_exec($ch2);
curl_close($ch2);
// var_dump(json_decode($result, true));
$output = json_decode ( $result );

这是执行PHP代码后的结果:

HTTP/1.1 302 Found Date: Fri, 17 Feb 2017 03:59:00 GMT

如何根据上述cURL选项获取JSON?

1 个答案:

答案 0 :(得分:1)

为什么在使用cookiefile和cookiejar时手动设置cookie标头?这不应该是必需的。

您收到setcookie标头也很可疑,可能服务器不接受您发送的会话cookie。

另外,为什么不在第二个请求中忽略无效的SSL?

最后,为什么不在第二个请求上发送相同的用户代理?

我想如果你解决了这些问题,你会看到预期的行为。
