PHP 登录 REST API

Question

我正在尝试创建一个 REST API 并寻找一种使用 PHP 登录的方法，该文档提供了一个使用 Python 的登录示例，但我不知道如何使用 PHP 执行此操作。我在想下面是否有 Python 代码的 PHP 版本。

见下面代码:

def login():
global sessionID
req = urllib2.Request("https://<host>/appserver/j_spring_security_check")
req.add_data(urllib.urlencode({"j_username" : "admin","j_password" :"demoserver"}))
res = opener.open(req)
sessionID = getCookie("JSESSIONID",cookies)
# Get the value of JSESSIONID cookie
response = res.read()
return

如果我需要使用 PHP 登录 Web 服务(考虑 Python 示例)，我可以使用什么登录脚本(PHP 版本)？

附加信息:

Logging into the web service requires a JSON object as the request body with user name and password:

Successful execution of the method will return a Cookie session Id

Example request JSON: {"j_username" : "username", "j_password":"*******"}

User needs to parse the cookies and extract cookie with key as JSESSIONID. This JSESSIONID value needs to be added manually in all headers of the Rest calls

“Cookie”: “JSESSIONID=“ + cookieValue

另一个使用 Python 的例子:

//Request for All Apps
global sessionID
sID = "JSESSIONID="+sessionID
uri = "https://<hostname>/appserver/portal/api/1.0/apps"
req = urllib2.Request(uri)
req.add_header("Content-Type", "application/json")
req.add_header("Cookie", sID) # Header
req.get_method = "lambda: GET” # Method Type
res = opener.open(req) # URL Call
response = res.read()
return response

请求 header :

当我尝试使用 Linux 进行 curl 时，代码如下。

curl -k -i -H "Content-type: application/x-www-form-urlencoded" -c cookies.txt -X POST https://192.168.100.100:444/appserver/j_spring_security_check -d "j_username=admin&j_password=demoserver"

这是 linux curl 的结果，自从我被路由到欢迎页面后，我相信它已成功连接。

但是当我尝试在代码中使用 PHP curl 时，仍然无法连接。

<?php
$ch = curl_init();
$url  = "https://192.168.100.100:444/appserver/j_spring_security_chec‌​k";
$postData = 'j_username=admin&j_password=demoserver';
curl_setopt($ch, CURLOPT_URL,$url);
curl_setopt($ch, CURLOPT_POST, 1); // -X
curl_setopt($ch, CURLOPT_POSTFIELDS,$postData); // -d
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
    'application/x-www-form-urlencoded'
)); // -H
curl_setopt($ch, CURLOPT_COOKIEJAR, 'cookies.txt'); // -c
curl_setopt($ch, CURLOPT_COOKIEFILE, 'cookies.txt'); // -c
curl_setopt($ch, CURLOPT_HEADER, true); // -i
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false); // -k
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
echo curl_exec ($ch);
curl_close ($ch);

这是我浏览器中生成的 header 。 请求网址:http://localhost/curl.php 请求方式:GET 远程地址:127.0.0.1:80 状态码:200 OK 版本:HTTP

Answer 1

您需要使用 CURL

请求 url :"https://<host>/appserver/j_spring_security_check"

并发布数据:"j_username=admin&j_password=demoserver"

所以你的代码看起来像

<?php
    $ch = curl_init();
    $url  = "https://<host>/appserver/j_spring_security_check";
    $postData = "j_username=admin&j_password=demoserver";
    curl_setopt($ch, CURLOPT_URL,$url);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS,$postData);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    $server_output = curl_exec ($ch);
    echo $server_output;
    curl_close ($ch);
?>
