cURL equivalent in JAVA

Question

I am tasked with writing an authentication component for an open source JAVA app. We have an in-house authentication widget that uses https . I have some example php code that accesses the widget which uses cURL to handle the transfer.

My question is whether or not there is a port of cURL to JAVA , or better yet, what base package will get me close enough to handle the task?

Update :

This is in a nutshell, the code I would like to replicate in JAVA:

$cp = curl_init();
$my_url = "https://" . AUTH_SERVER . "/auth/authenticate.asp?pt1=$uname&pt2=$pass&pt4=full";
curl_setopt($cp, CURLOPT_URL, $my_url);
curl_setopt($cp, CURLOPT_RETURNTRANSFER, 1);
$result = curl_exec($cp);
curl_close($cp);

Heath , I think you're on the right track, I think I'm going to end up using HttpsURLConnection and then picking out what I need from the response.

Answer 1

Exception handling omitted:

HttpURLConnection con = (HttpURLConnection) new URL("https://www.example.com").openConnection();
con.setRequestMethod("POST");
con.getOutputStream().write("LOGIN".getBytes("UTF-8"));
con.getInputStream();

Answer 2

I'd use the Commons Http Client . There is a contrib class in the project that allows you to use ssl.

We're using it and it's working well.

Edit: Here's the SSL Guide

Answer 3

jsoup

The jsoup library fetches a URL as the first step in its HTML scraping and parsing duties.

Document doc = Jsoup.connect("http://en.wikipedia.org/").get();

Answer 4

Try Apache Commons Net for network protocols. Free!

Answer 5

如果您需要比Commons Net提供的功能更多的功能，也可以尝试从Apache项目中尝试[ http://hc.apache.org/]（HTTP组件）。

Answer 6

you can try curl-to-java lib to convert curl php code to java code https://github.com/jeffreyning/curl-to-java demo like this

public Object curl(String url, Object postData, String method) {

CurlLib curl = CurlFactory.getInstance("default");
ch = curl.curl_init();
curl.curl_setopt(ch, CurlOption.CURLOPT_CONNECTTIMEOUT, 1000);
curl.curl_setopt(ch, CurlOption.CURLOPT_TIMEOUT, 5000);
curl.curl_setopt(ch, CurlOption.CURLOPT_SSL_VERIFYPEER, false);
curl.curl_setopt(ch, CurlOption.CURLOPT_SSL_VERIFYHOST, false);
String postDataStr = "key1=v1";

curl.curl_setopt(ch, CurlOption.CURLOPT_CUSTOMREQUEST, "POST");
curl.curl_setopt(ch, CurlOption.CURLOPT_POSTFIELDS, postDataStr);
curl.curl_setopt(ch, CurlOption.CURLOPT_URL, "https://xxxx.com/yyy");
Object html = curl.curl_exec(ch);
Object httpCode = curl.curl_getinfo(ch, CurlInfo.CURLINFO_HTTP_CODE);
if (httpCode != null && 200 == Integer.valueOf(httpCode.toString())) {
    return null;
}
return html;
}
