从java打开URL [英] Opening an URL from java

问题描述

我们正在为bigquery编写一个开源的jdbc驱动程序，并遇到了以下问题：

we're writing an open-source jdbc driver for bigquery, and ran into the following problem:

我们想要在安装了Oauth 2的情况下授权我们的驱动程序应用。在Windows XP，Windows 7 x64，Windows 7 x64 + RDP上它工作正常。但是在Windows服务器2008 R2 + RDP的测试平台上，它失败了。

We want to authorize our driver with Oauth 2 as an installed application. On windows xp, windows 7 x64, windows 7 x64 + RDP it works fine. But on the testbench which is a windows server 2008 R2 + RDP it fails.

基本上，我们打开一个Web浏览器，他登录，我们收到回复，并进行身份验证用户。

Basically, we open a web browser, he logs in, we catch the reply, and authenticate the user.

以下是网址开放的代码：

Here's the code for the url opening:

    private static void browse(String url) {
    // first try the Java Desktop
    logger.debug("First try the Java Desktop");
    if (Desktop.isDesktopSupported()) {
        Desktop desktop = Desktop.getDesktop();
        if (desktop.isSupported(Action.BROWSE))
            try {
                desktop.browse(URI.create(url));
                return;
            } catch (IOException e) {
                // handled below
            }
    }
    // Next try rundll32 (only works on Windows)
    logger.debug("Try the rundll32");
    try {
        Runtime.getRuntime().exec(
                "rundll32 url.dll,FileProtocolHandler " + url);
        return;
    } catch (IOException e) {
        // handled below
    }
    // Next try browsers
    logger.debug("Try with browsers");
    BareBonesBrowserLaunch.openURL(url);
}

我想到的是：Bar​​eBonesBrowserLaunch不会打开链接，也不会FileProtocolHandler。

What i figured out is: BareBonesBrowserLaunch doesn't open the link, nor does the FileProtocolHandler.

URL长度略低于250字符。

The URL lenght is a little bit under 250character.

任何帮助都将不胜感激！

Any assistance would be appreciated!

推荐答案

使用 java.net.HttpURLConnection

URL myURL = new URL("http://example.com/");
    URLConnection myURLConnection = myURL.openConnection();
    myURLConnection.connect();
